On the morning of April 28, 2022 was held to celebrate the May 1st International Labor Day and the National May 1st Labor award and the National worker pioneer commendation meeting. The National Labor Congress won the 1st and 5th national labor award in 2022. 200 units won the title of National May 1st labor certificate, 966 employees won the title of National May 1st Labor Medal, and 956 collectives won the title of national worker pioneer.

What is particularly noteworthy is that in the list of winners of the "National May Day Labor Medal" in 2022, five comrades, namely Pei Baolin, Qian Qinfang, Jiang Zhengtao, Che Shehai and Guo Chao, who have won the honor of "China's textile craftsman" in the textile industry, are happy to be on the list of "National May Day Labor Medal".

　　 Pei Baolin Jingwei intelligent textile machinery Co., Ltd. spindle factory tool equipment repair team leader, senior technician

Won the title of "Chinese textile craftsman" in 2021

Won the title of "National May 1st Labor Medal" in 2022

"If you have any problems, find master Pei. He is the" know it all "in our factory. This is a common saying of workers in the spindle factory of Jingwei intelligent company. It is also a great affirmation of Pei Baolin, the head of the tool and equipment repair class.

Pei Baolin, 52, has been in the first line for 30 years. He is now the head of the tool and equipment repair class of Jingwei intelligent company spindle factory. He is modest and easy-going. Wherever there are technical problems, he will be able to solve the problems in his hands, whether it is equipment debugging, technical guidance, program optimization and quality control.

In 1990, Pei Baolin graduated from technical school and was assigned to the special parts division of Jingwei intelligent company, becoming an ordinary lathe worker. His technical measures group is responsible for the design and manufacturing of cotton textile special parts machine, which is a team with strong comprehensive skills. Pei Baolin, who had been busy with the turning process several times, watched the masters busy like a top one by one, but he could only do it in a hurry. This made him determined to attack the skills of various types of work such as tongs milling and grinding in the shortest possible time. He is diligent, studious and progressive, so that the masters like to teach each other their unique skills. Xu Kui, an old technician who has been away from Jingwei for more than 20 years, said with pride: "this child is smart and diligent, and is a rare good worker.".

"Success depends on ambition, and industry is extensive and diligent." After years of hard work and hard work, Pei Baolin has gradually grown into an excellent technical worker with excellent skills and rich professional knowledge. He has won the championship of the company's lathe worker skills competition for many times, and has stepped out of the longitude and latitude to go to all kinds of competitive venues, taking the lead in the technical competition. Nowadays, in Jingwei intelligent company, as long as it involves parts processing problems, everyone will think of Pei Baolin for the first time, and he will always overcome the problems with various "unique skills".

In 2008, Pei Baolin was transferred to be the group leader of the steel ingot plate group. The characteristic of the ingot plate group is the uniform numerical control processing equipment, but Pei Baolin has never been in touch with numerical control, and does not know what G code and M code. Therefore, he handled the class work during the day, while learning and operating at night. In two months, he got the basic theory and programming technology of numerical control. He and his team members tried to integrate process flow, change processing methods, innovate self-made tooling, and improve performance management, so that the efficiency of pressing yarn cutter in the key process of steel spindle disc group was increased by 4 times in 3 months, making the steel spindle plate the first inspection free product in spindle factory of special service department of Jingwei intelligent company.

Pei Baotou always insists on "innovation in the process of on-site innovation" and "subsequent innovation". Once upon a time, the ingot foot cleaning machine of the assembly team would be stuck five or six times a day, which seriously affected the overall work efficiency of the team. Pei Baolin squatted on the scene for three days in a row, analyzed the main causes of the problem, and boldly changed the position of fixing parts from suspended guidance mode to base fixation, and the problem of material jam was solved quickly. However, the variety of parts and single fixed tooling can not meet the demand of variety diversity. He insisted on continuous improvement and skillfully set a tooling outside the ring-shaped tooling to ensure the effective fixation of various types and models of parts.

It is with this kind of courage to change skillfully that Pei Baolin becomes the "problem terminator" who competes with the front-line teams for advice. According to incomplete statistics, up to now, Pei Baolin has 11 independent improvement projects, such as self-made assembly line of ingot and gall joint, assembly of ingot foot cleaning machine, design and manufacture of elastic tube deburring special machine, which has won awards at all levels and created economic value of more than 4 million yuan for the company.

A single flower is not a spring, but a hundred flowers are in full bloom. In 2014, Jingwei intelligent company established the first innovation studio named after an individual - "Pei Baolin Innovation Studio". How to use the studio platform to help young people become talents and better serve the production has become a subject that Pei Baolin has been thinking about and constantly exploring. Since its establishment for 8 years, "Pei Baolin Innovation Studio" has played an irreplaceable role in the key work of spindle technology and product production of Jingwei intelligent company. It has achieved more than 200 innovative achievements and trained a number of technical talents for the enterprise.

With the three "golden keys" of diligent study, courage to change and dare to challenge, Pei Baolin has gradually grown from an ordinary lathe worker to a "craftsman type talent" praised by the whole company.

　　 Qian Qinfang Group leader, senior engineer, production technology department of Shenghong Group Co., Ltd

Won the title of "Chinese textile craftsman" in 2021

Won the title of "National May 1st Labor Medal" in 2022

Qian Qinfang's first impression came from her plain and generous work clothes and her easy-going smile.

Entering Qian Qinfang's office, all kinds of work supplies on the desk are placed in an orderly manner, and the master's standardized style is revealed everywhere. In the cabinet against the wall, half of the cabinet work log is neatly placed, and a copy is opened casually, which records the problems encountered in work, solutions and test results. Qian Qinfang has accumulated more than 50 notebooks like this. Pile upon pile of notes, Qian Qinfang nearly 30 years of dyeing career struggle and persistence.

In 1992, as a "seedling", Qian Qinfang was selected by enterprises to study in the dyeing and finishing college class held by Suzhou University for two years. From then on, Qian Qinfang embarked on the road of textile dyeing development.

In 2000, pingqin Hong became the first choice of the company's color matching consulting company. In order to help the branch plant improve the first-time success rate, Qian Qinfang and the team members spent more than two years on the systematic proofing and analysis of hundreds of dyes in the whole company. From this time on, Qian Qinfang's heart buried the desire to do standardized color matching technology.

In 2010, Qian Qinfang proposed the concept of "central color database". However, foreign color equipment manufacturers at that time did not agree to open the data interface. At the same time, the information level of the company could not reach the level of data exchange. Qian Qinfang is not discouraged. She firmly believes that the automation level of the electronic information industry can also be achieved in the traditional textile printing and dyeing industry, and there can be "lighthouse factories" in the printing and dyeing industry. Since then, Shenghong printing and dyeing has opened the curtain of the biggest self transformation since the establishment of the factory. As high as the ideal, the difficulty is. Shenghong printing and dyeing Co., Ltd. not only has its own branch factory, but also has merged branch factory and cooperative branch factory. At the same time, it implements the development strategy of "one factory, one product". The equipment model is complex, the product types are various, and the development degree and automation level of each branch factory are not the same. Qian Qinfang has a lot of work ahead of him. The "massive" basic data need to be collected, sorted out, analyzed, discussed and formulated, New problems will be encountered at any time, and new sub projects will be formed to be solved. Over the past few years, Qian Qinfang has led the technology and information team to overcome all difficulties. Focusing on the "integration of industrialization and industrialization", Qian has successively carried out more than 70 key projects, inspected and imported more than 600 sets of equipment, and developed information systems such as MES and CRM. The company's overall automation and informatization has changed dramatically.

In 2016, Qian Qinfang, who has been entrusted with great responsibility by the group with outstanding innovation achievements, thinks that the time has come to promote the color management system. She once again proposed the optimized "textile color big data system". The color matching module of the system gives up the mode of color matching based on the dye properties of foreign color equipment manufacturers, and chooses to develop the color finding system independently. Based on more than 400 dyes, more than 26000 kinds of fabric substrates, and more than 2 million color formulas added each year, a huge basic database was formed, and the color search function was developed to solve the problem that the software of foreign equipment manufacturers could not be applied to various substrates; The color correction algorithm based on experience is developed to solve the problem that the tristimulus matching algorithm is not applicable, which breaks the long-term monopoly of foreign companies in this field.

At present, Shenghong group has realized the automation of proofing equipment, intelligent formula and intelligent process. The first-time success rate of color matching has reached more than 90%, and the difficulty of proofing operation has been reduced. Compared with a few years ago, the color matching efficiency has been improved by more than 40%, and the labor intensity has been reduced by at least 50%.

Now, Qian Qinfang spends most of her mind and energy on "helping and guiding". In her opinion, it is the key to cultivate more high-level technicians to realize standardized operation, and the continuous improvement of one-time dyeing success rate is the key. With outstanding achievements, Qian Qinfang's team was awarded "Jiangsu worker pioneer".

　　 Jiang Zhengtao Weft knitting worker and senior technician of Jifa Group Co., Ltd

Won the title of "Chinese textile craftsman" in 2017

Won the title of "National May 1st Labor Medal" in 2022

Jiang Weitao, a 40 year old craftsman in the textile industry, has gone from a master craftsman to a master craftsman.

Weft knitting workers in the textile industry were called "weavers" in ancient times, and most of them were skillful women workers. After graduating from high school, Jiang Zhengtao entered Jifa group and became a textile worker. At that time, there were not many male textile workers. Jiang Zhengtao was the one who dared to eat "crab". Jiang Zhengtao said that weft knitting workers are engaged in many processes, such as yarn hanging, connector, tail yarn connection, needle changing and cloth laying, which are important links in the whole textile industry. Whether the fabric is woven well or not is an important criterion for a weft knitting worker.

When he first entered the factory, Jiang Zhengtao started as an apprentice. Sometimes, he had many problems. However, he was a clumsy bird and flew first. He came to the company early every day to practice basic skills. He began to practice repeatedly from the connector. He humbly asked his master for advice. When he came home at night, he summarized the skills he had learned in the day. Slowly, he started hanging yarn, connecting connector, connecting tail yarn, identifying yarn count, etc From the operation of two looms to the operation of 4-5 looms, from apprentice to skilled weft knitting worker, the annual quality index reaches more than 99.8%, and the quality and output are higher than the average value of the whole factory.

In Yihe company of Yifa group, a large textile and garment enterprise in China, Jiang Zhengtao is a "skilled craftsman" among many weft knitting workers. With his skilled skills and hard research, he has created a number of outstanding achievements among the "needle and thread brain", and the products produced by him and his workers are also sold to the international market. 　　

In the workshop where Jiang Zhengtao works, dense cotton yarn lingers above the machine. According to Jiang Zhengtao, the cotton cloth woven on this machine is 2 meters wide, which requires 102 cotton yarns. Each cotton yarn has a fixed position, and it is not possible to make a wrong one.

"It sounds like a very simple job, but in the eyes of weft knitting workers, it is a technical work. If the thread ends are connected quickly, more cloth will be woven; if the thread ends are small, there will be no defects on the cloth surface." Jiang Zhengtao said that if the thread is broken and the tail yarn is replaced, they will have to pick up four or five hundred threads a day. While the connector sounds like a small thing, it is actually a "big job" in textile work. It can connect the broken thread head in time, and it is necessary to determine the position of the broken needle by observing the defects on the cloth surface and replace it in time. Each loom has 90 yarn feeders and 2000-3000 knitting needles. If you don't observe carefully, you can't see the cotton thread finer than the hair. At the same time, you have to observe the defects on the cloth surface through the glass all the time. This kind of working state will last for 8 hours or even longer. You can imagine its test to the eyes. At present, Jiang Zhengtao is very skilled in the techniques of connector, needle mounting and yarn hanging. For example, ordinary workers can load about 10 pieces at a time, while Jiang Zhengtao can load about 20 pieces at the same time, which only takes less than 10 seconds.

Another "unique job" of weft knitting workers is "looking for bad needles". Take the cloth surface with a width of 2 meters as an example. The machine needs to install 2640 needles to work at the same time. These needles are arranged in order, and each has a designated position and number. Due to long-term friction, these needles are prone to problems. Weft knitting workers need to find out the fabric defects by naked eyes, find out which needle to find, and then repair or replace them. If the processing is not timely, a meter long remnant can be woven in one minute. As the woven fabric rotates all the time under the machine, the weft Weaver has to look through the glass to see if there are any defects on the cloth surface, which naturally increases the difficulty. In 2011, Jiang Zhengtao won the eighth place in the national textile industry weft knitting professional skills competition. In 2014, he once again participated in the national textile industry weft knitting professional skills competition, won the first good result, and won the honorary title of "national technical expert". In 2016, Jiang Zhengtao won the honor of "national textile industry model worker" at the national textile industry advanced collective, labor model and advanced worker commendation meeting held in the Great Hall of the people in Beijing.

As a worker, Jiang Tao should continue to work hard to improve his skills.

　　 Che Shehai Chief designer and senior engineer of Qingdao Hongda Textile Machinery Co., Ltd

Won the title of "Chinese textile craftsman" in 2021

Won the title of "National May 1st Labor Medal" in 2022

In the eyes of employees of Qingdao Hongda Textile Machinery Co., Ltd., cheshehai is the leader and chief designer of the core technology of the company's products. There is an unyielding strength in cheshehai's bones, which makes his dream of textile machinery experts come true.

From October 2007 to June 2008, the technical team led by Che Shehai issued a military order, broke through a number of technical blockades, and successfully developed the fine contact automatic winder. As one of the ten new complete sets of key equipment of textile machinery supported by the state during the Eleventh Five Year Plan period, the project was paid attention to by all walks of life in 2011 at the national major scientific and technological achievements exhibition.

In recent years, Che Shehai has led the technical team to continue to tackle key problems, and has achieved milestone achievements.

One is an efficient intubation device. This technology fills in the gap at home and abroad and belongs to the international leading level. The winder is generally equipped with 60-72 spindles, especially for the production of Coarse Count Yarn less than 21 inch count, it needs to be equipped with three sets of generating mechanism, and the intubation speed has become the bottleneck of the whole winder. Foreign counterparts have successively developed double intubation mechanism with complex structure and corresponding patent protection. After nearly one year's research, cheshehai and the technical team have developed an efficient intubation device. The device has simple structure, and the speed of intubation is nearly double that of the original intubation mechanism. The number of intubation tubes in one set of intubation mechanism can reach that of two sets of foreign intubation mechanisms. Moreover, it completely solves the requirements of the original intubation mechanism on the yarn forming, low efficiency, and high efficiency The actual intubation speed is more than 55 / min. At present, the device has obtained four national invention patents, three Japanese invention patents, three Italian invention patents and three German invention patents.

The second is the trolley. This device fills in the gap in China. The original winders are all manually dropped. Due to the continuous reduction of labor force in textile enterprises, it is required to use a trolley to drop the drum. Through continuous efforts, the kelp team of cheshe has designed and developed three generations of drop tube cars. The first generation is mainly mechanical, belonging to the initial stage. The second generation trolley fully realizes the mechanical and electrical integration, and invents a new pipe laying device, which solves the problem of high requirements for single ingot of the pipe laying device, and greatly improves the success rate of pipe laying. The new branch mechanism and automatic detection and diagnosis device have improved the stability and reliability of the dropping barrel trolley. Now, it has been widely used in automatic winding machine. The third generation of doffing trolley has realized intellectualization, which can realize mutual tube borrowing between single spindles, separate branch pipe, separate yarn grabbing, automatic head formation when there is no bobbin yarn, yarn quality tracking and fault self diagnosis, etc., which reduces the debugging difficulty of the drop drum trolley and further improves the success rate of dropping tube.

At the same time, it solves the problem of single bobbin jam in the production of the whole machine.

At the end of 2020, the VCrO type automatic winder jointly developed by Che Shehai and the team stood out in several selection projects and won the first prize of science and technology progress award of China Textile Industry Federation.

When it comes to work, Che Shehai said with a smile, "in this life, people should constantly strive, keep running, and master a skill on the ground. Even if it is an ordinary post, it will shine because of hard work."

　　 Guo Chao Hengtian Heavy Industry Co., Ltd. processing division welder class leader, senior technician

Won the title of "Chinese textile craftsman" in 2018

Won the title of "National May 1st Labor Medal" in 2022

Guo Chao, 36, has the title of senior welding technician and is also a special equipment operation skill teacher of Hengtian Heavy Industry Co., Ltd. From 2016 to 2020, he was employed as the "chief employee" of the company for five consecutive years and the first batch of "chief technician" in 2021. Guo Chao sticks to his position as a welder. With hard work, hard core technology and dedication, he shows the unique style and charm of welding workers in the new era.

In 2003, Guo Chao, who studied in technical school, entered Hengtian heavy industry and began his welding practice career. In order to master the post skills as soon as possible, Guo Chao always takes the welding master as an example, practices the basic skills diligently, and studies the single side welding and double side forming technology in each spatial position; In order to solve the welding problems he encountered, he did his best to turn over the information, ask colleagues, keep thinking and repeatedly weld. If the problem can not be solved, he absolutely "will not stop work" or "do not let go". With this tenacity, Guo Chao solved one welding problem after another, and his own welding technology was constantly improved. He was rated as an excellent student of the company in his internship.

Guo Chao not only practiced basic skills, but also made full use of the technology competition platform to compete with his peers. He even drove hundreds of miles to seek advice from welding experts from inside and outside the industry, and exchanged skills in the process of welding. Guo Chao summed up a set of operation methods suitable for himself. He got excellent results in the welder group of the 5th and 7th skill competitions of China Hengtian Group Company, and won the fifth place in the 14th "Zhenxing Cup" national vocational skills competition Henan Province.

Welding is a kind of technology, but for Guo Chao, welding is an art with unspeakable charm. As the head of the welding team of the second work department of the processing business department, he devoted himself to the research of titanium alloy welding technology for new materials. Through the improvement of tooling, the reduction of heat input, and the self-made protective cover of various shapes and sizes, the test could only be carried out on a 300 mm test plate, It is successfully applied to the actual welding process with a single weld length of 2800 mm, which makes the silver white rate of the weld surface reach more than 98%, which provides valuable reference for titanium alloy welding of the company. Guo Chao's welding work is "striving for perfection". The green fiber complete set equipment project is the environmental protection and green emerging chemical fiber products promoted by the company in the next 10 years, which has a good market prospect. Among them, the melt pipeline in the green fiber project starts from the evaporation and dissolving machine, passes through the premixing tank, filter, booster pump, and is distributed to the spinning machine, covering the whole system. It is responsible for the whole process of raw liquid transportation, and is responsible for the feeding supply of all equipment. It is called the "meridians" of the green fiber project. The melt pipeline of filter section is the core part of the whole pipeline, which is divided into two layers of rubber inlet and outlet. After the pipeline is welded with 8 filters, the horizontal error of filter should be controlled within 0.1mm. As a cold weldment, such a high tolerance requirement is the first time in the company. Compared with other parts, the shape and structure of this section of pipeline are more complex, and the space position of flange surface is inconsistent; Secondly, it is very difficult to assemble and weld the flange one by one, and to ensure that the assembly of the filter is very difficult. In order to ensure that the filter can meet the production process requirements, the pipeline section is welded by manual argon arc welding, and all dimensions need to be ensured by reserving shrinkage in advance and controlling deformation during welding. The first filter section pipeline of hongtaiding took more than half a year from the beginning of welding to the end of assembly. In order to ensure the high quality and high efficiency production of the subsequent filter section pipeline, Guo Chao and the team recorded the shrinkage of each weld and found that under the same welding parameters, the different welding sequence had a great impact on the welding shrinkage and deformation. Through the optimization and improvement of welding process and the control of welding deformation in the welding process, compared with the previous, the construction period of the in and out rubber pipe road is shortened to 1 month, the overall assembly level error is controlled within 0.1 mm range, and the difficulty coefficient of precision dimension control of cold welding technicians is constantly updated. Guo Chao used the ordinary welding in his hands to lead the welder team members to create an "extraordinary achievement" belonging to them.

"To be an expert in welders" has always been Guo Chao's career pursuit. He not only practiced hard, but also studied hard. He passed the pass time and again on the road of "obtaining certificates". He obtained the pressure vessel operation certificate in 2004, the senior welder qualification certificate in 2008, the technician qualification certificate in 2014, the special equipment operation skill teacher certificate in 2015, and the senior technician qualification certificate in 2018, In 2017, we completed the remote training of team leader's post ability in Tsinghua University. Seeing the excellent colleagues with undergraduate and postgraduate diplomas around him, Guo Chao began to quietly use his spare time to learn knowledge other than welding. In 2010, he passed the self-study examination for information technology application and management specialty in Information Technology University of PLA, and became a new era worker with a bachelor's degree in four and a half years.

In 2018, "Guo Chao Labor Model Innovation Studio" was established. Guo Chao and the members of the studio cherish the rare learning opportunities. Through the joint efforts of four key research groups, namely cold welding group, turning and grinding group, boring and milling group and special technology group, by the end of 2021, the studio has completed 37 innovative achievements, 30 achievements transformation, 7 working methods and 9 process optimization suggestions, Promote the application of titanium alloy welding process, gantry welding robot, green fiber melt pipeline one-sided welding and two-sided forming technology to textile machinery and equipment products, which has reduced the cost and increased the economic value of the company by 10.4512 million yuan. "Guo Chao Labor Model Innovation Studio" has been successively rated as Zhengzhou model and craftsman talent innovation studio, Henan Province demonstration "model worker and craftsman talent innovation studio".

With his ingenuity, Guo Chao interprets the craftsman's spirit in every detail of welding technology.
