Abstract:

According to the complicated mechanical processing architecture and high energy consumption of the knitting pattern of conventional rircular jacquard knitting machine, it presented weaving pattern using electromagnetic-permanent directly driving dnitting needle, and simplifying conventional mechanical transmission structure of circular weft knitting machine. This paper analyzed permanent knitting needle force model driven by electromagnetic force on the bais of previous work, revealed the law of multi-needle suspension motion in axial direction, established suspension knitting needle axially driving model and control algorithm, realized conventional circular machine knitting process in "trip-work station" and drove needles in "zero-transmission" in lossless model, explored multi-needle suspension driving woven in particular way, and provided theoretical guidance for further exploring suspension driving needle to replace conventional technology in weaving process and for the realization of control and adjustment in whole kniting process.

Key words: high speed axial suspension needle, trip-position knitting technology, zero transmission, motion trajectory
