Zhejiang Wanli "Key to Intelligent High Speed ​​Rapier Loom Driven by Switched Reluctance Motors

On June 28, 2019, commissioned by China National Textile and Apparel Council, China Textile Machinery Association was hosted by Zhejiang Wanli Textile Machinery Co., Ltd., Zhejiang Institute of Technology, Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences, Zhejiang Zhongzi Electromechanical Control Technology Co., Ltd. participated in the research and development of the "Key Technology and Application of Intelligent High Speed ​​Rapier Loom Driven by Switched Reluctance Motor". Wang Shutian, honorary president of China Textile Machinery Association, attended the meeting. The appraisal meeting invited seven experts from Tianjin University of Technology, Professor Jiang Xiuming and Shanghai Textile Engineering Society, to form an appraisal committee.

The key technology and application of the intelligent high-speed rapier loom driven by switched reluctance motor has developed a switched reluctance motor suitable for high-speed rapier looms. The parameters and structure optimization are carried out based on the research of motor structure and performance. . The project innovatively designed the hydraulic drive mechanism to realize the search for the main drive system. It optimized the spindle structure with static balance effect and improved the speed of the loom. The phase-adjustable weft insertion mechanism was designed with the amplitude-modulus spatio-temporal motion unchanged. The characteristics of the weft yarn transfer are reduced; the large-span, high-torque vertical shaft transmission mechanism has been developed to solve the problem of high-density and heavy-duty jacquard opening transmission. The project adopts the precise positioning control technology of the loom spindle to realize the automatic adjustment and weft finding of the heald time; the automatic calibration and adjustment of the parameters of the loom, the monitoring and management technology of the loom operation information are developed, and the intelligent level of the loom is improved. . At the same time, it has also developed technologies such as adjustable coil winding pressure technology, active driving thin weft dense fabric conveying technology, independent bobbin storage and other tension retraction techniques, which have improved the adaptability of the loom, and have a market in the industrial field. Technical advantages.

The experts of the appraisal committee inspected the site, listened to the technical development summary report, inspection and new report, user report, etc. of the project undertaker, and reviewed the project identification data. After the inquiry and discussion, the appraisal committee considered that “switched reluctance motor drive The key technology and application of the intelligent high-speed rapier loom has reached the international advanced level. It agrees that the project will pass the scientific and technological achievements appraisal and proposes to accelerate the marketing application.
