A Study Of JF Type Drafting Equipment Performance On Ring Spinning Machine

The equipment on ring spinning machine came to the fore various types since dozens of years, but there are four types were the most mature, SKF type, INA-V type,R2P type and HP type, these equipment made by the foreign nation. In spite of created the various drafting equipment on the ring spinning by the domestic researcher and the spinning accessories plants, example R2V types, but all derived form the four types aforesaid. The JF type equipment is the patent product invented by KUN SHAN JING FENG MACHINE CO.LTD. Created the new structure of the top and bottom apron cradle, as well as the element of the press structure on this equipment. The JF type equipment have excelled performance on part probation. As a new type drafting equipment ,there is few analysis and summary on the theory and art at present. This paper analyzes and mimics the theory and of the JF type equipment structure, and making comparison between JF type and SKF type, found the best-art and the rang applied to. which will provide later science study and the production with guidance.The main content of the paper is:(1) Analyzes and mimics the theory of the JF type equipment structure, include the calculate of the floating zone distance, friction force zone distribution and fiber speed change point mathematic model of the JF type drafting equipment on the ring spinning machine.(2)Spinning testing and art optimum.(3) Making comparison between JF type and SKF type.
