Research on the Needle Selecting Machine of Computerized Jacquard Circle Knitting Machine Based on Piezoelectric Ceramics

In order to overcome the shortage in the traditional mechanical needle selecting machine of jacquard circle knitting machine, a new needle selecting machine based on piezoelectric ceramics is designed. This paper expands on the structure of needle selecting machine and its principle. The piezoelectric ceramics have a micro-displacement with the different flower type. The movement is enlarged by the needle piece and the needle moves to the requested location. Therefore, the three movements of needle selecting machine are realized such as the loop formation, loop accumutional and float adjustment loop.
