A few days ago,Qingdao Dongjia Textile Machinery (Group) ** Chief Engineer Ji HejuAwarded by the China National Textile and Apparel Council and the China Finance and Trade Tobacco Textile Trade Union".China's textile master craftsman"Honorable title. Since joining Qingdao Jiaonan Textile Machinery Factory (the predecessor of Qingdao Dongjia Textile Machinery (Group)**), Chief Engineer Jiheju has been focusing on the design and research and development of textile equipment carding machinery for 40 years.
Qingdao Dongjia Textile Machinery (Group) has a complete processing and assembly of the whole process of machinery manufacturing technology, is the current domestic production scale, a full range of textile carding machinery professional manufacturing enterprises. The main production and operation of cotton spinning and carding equipment and pre-spinning unit equipment, wool and semi-worsted carding equipment, chemical fiber carding and non-woven complete sets of equipment, special fiber carding and blended carding equipment, shuttleless looms and other five series of nearly 100 specifications of products, carding machinery products production and sales in the forefront. The company's products were exported to Bangladesh for the first time in 1996, and after nearly 30 years of foreign market development, the products are exported to more than 30 countries and regions in Southeast Asia, South America, Africa, Central Asia and Eastern Europe, and foreign sales account for 30%.
Qingdao Dongjia Textile Machinery (Group)** has won many awards for its outstanding performance in the field of textile machinery. The company's technology center is a state-level enterprise technology center, a research and development center for cashmere carding combined machine products in China's textile machinery industry, an engineering technology research center in Shandong Province, and an industrial design center in Shandong Province. The company has successively won the National Textile Industry Quality Award, the leading backbone enterprise of Shandong Province high-quality textile machinery production base, and the Shandong Province Technology Innovation Demonstration Enterprise.
Behind these achievements is the hard work and wisdom of the company's technical talents, and Ji Heju is one of the outstanding representatives. Jiheju is good at tackling technical problems, especially in the research of special fiber carding, and is the technical leader of the enterprise, and has made outstanding contributions to the combination, serialization, modularization and automation, intelligence, complete set and high efficiency, low consumption and flexible carding of products. In recent years, it has trained more than 200 technical backbones and high-skilled talents. In the past 40 years, he has been unremittingly researching textile equipment carding machinery technology, and his innovative technological achievements have won 158 national authorized patents, including 36 international and domestic invention patents; He has won 1 second prize of the National Science and Technology Progress Award and 13 provincial and ministerial science and technology progress awards.
Solve the problem of fiber carding and lead the market trend
Through in-depth market research, different customers use different raw materials to comb, to provide fast production services and simple replacement of varieties, shorten the manufacturing supply cycle of accessories and reduce costs, while improving efficiency. Ji Heju believes that the confusion and pain points of customers are the direction of product development. When the customer reported that the fiber damage of the traditional carding machine was a "headache", Ji Heju visited and investigated a number of customers, inspected the fiber production in the operation of the equipment, consulted the relevant technical data and repeatedly deduced, calculated the speed of each component in detail, and the test results finally met the standard design requirements. He used the respective advantages of wool roller carding and cotton cover carding, coupled with novel and reasonable structural innovation and card clothing research, invented a patented technology product and applied it to new spinning equipment, which improved the spinning efficiency and reduced the fiber damage rate by 7% on average.
With the changes in the market, the market demand for specialty fiber products is increasing day by day. Jiheju puts the goal of research and development on special fiber semi-worsted carding equipment, opens up a precedent for new and multi-component fiber flexible carding, solves the carding problems of some special fibers such as cashmere, bamboo raw fiber, chitosan, seaweed, aramid, silk, kapok fiber, etc., and realizes the industrialization of high-quality semi-worsted yarn of special fibers. A domestic customer has purchased equipment from the company for 4 times, and the order has reached 60 units. Seeing that the results of his careful research and development have been recognized by customers, Ji Heju is more confident, and he has made the machine able to adapt to the good carding of the fiber length range of 8 mm to 88 mm, and to adapt to the worsted yarn from ultra-short fiber towel yarn, recycled cotton to ultra-long fiber. Especially in recent years, the spinning of long fibers has gradually become the trend of the market, the traditional carding machine and carding machine is difficult to achieve the ideal long fiber carding, Ji Heju led the technical team to launch the new equipment, to achieve the fine carding of 88 mm long fiber, not only better to retain the length and the wool particles are almost zero. The product won the patent award and the second prize of scientific and technological progress of China National Textile and Apparel Council. At present, Ji Heju is tackling the fine carding of fiber length of more than 120mm, which is his new goal of technical research.
As a technical leader of the enterprise, Ji Heju for the perfect design and trial production of complete sets of glass fiber nonwovens products, he stayed at the user's production site for more than 20 days, against the summer heat and the itching of glass fiber, he lay next to the machine to carefully observe and study the problem of fiber transfer difficulties in the carding process, after repeated pondering, changed the size of the leakage, adjusted the entrance angle and accelerated the transfer speed, and finally solved the problem of transfer, after the success of the test, this production line quickly entered the market, It has created good economic benefits for the enterprise.
Ji Heju believes that textile carding is a systematic project, which is related to product design, raw material opening and pretreatment, impurity removal and health preservation. Therefore, in addition to the structural innovation in the design of the unit, the key is how to achieve the optimization of the whole process equipment is the key research topic of his research. He innovatively applied the fine start-up machine and single axial flow of cotton spinning to the cashmere opening process, which increased the impurity removal efficiency by 50% and greatly reduced the total number of carding passes. In order to study the carding indicators of cashmere carding equipment, he repeatedly tested various process parameters, and sometimes for a data, he could stay at the workshop production site for 24 hours continuously. He studied the carding process, systematically optimized the card clothing, speed ratio, spacing, feeding amount, workshop temperature and humidity, the angle of the fleece board and the working surface, and finally overcame the problem of low yield, high consumption and large damage to cashmere for many years. In recent years, Jiheju's innovative intelligent combined cashmere automatic circulation carding equipment has won a number of national invention patents, reducing labor by 50%, improving carding efficiency by 30%, and reducing fiber damage by 2%.
Ji Heju has no festival (holiday) days all year round, and he leads the company's technical personnel to continue to innovate and forge ahead. The industry-university-research cooperation project he participated in, "Construction and Practice of the Continuous and Progressive Training System of Mechanical Research and Craftsman with "Three Connections, Four Synergies and Five Penetrations", won the second prize of Shandong Provincial Teaching Achievement Award. The project of "Key Technologies and Applications for Efficient Utilization and Reduction of Coolant in Quasi-Dry Manufacturing Process of Parts" won the first prize of Science and Technology Progress Award of China Federation of Commerce. The cooperative project "New and Efficient Combined Cashmere Carding Complete Equipment" won the second prize of Science and Technology Progress Award of China Chamber of Commerce.
