Two-needle bar electronic Jacquard warp knitting machine

Abstract

A double needle bar electronic jacquard warp-knitting machine comprises a looping device, a guide bar assembly and a transmission device. The guide bar assembly is provided with at least a piezoelectric ceramic jacquard guide bar; the front needle bar transmission mechanism and the rear needle bar transmission mechanism, the front deposition transmission mechanism and the rear deposition transmission mechanism, the guide chase comb upper pendulum transmission mechanism and the guide chase comb lower pendulum transmission mechanism in the transmission device are all eccentric wheel linkage transmission mechanism. Due to the adoption of the piezoelectric ceramic jacquard guide bar needle, the warp-knitting machine provided by the present invention can weave more complicated patterns, conveniently change patterns and simplify the structure. All transmission structures of the present invention adopt the eccentric linkage mechanism. Compared with the original cam linkage mechanism, the eccentric linkage mechanism has more complicated moving track, large moving traverse, high precision and more suitability for more complicated patterns. The rotation speed of the machine can be further increased, which is conducive to increasing the production efficiency.

Description

technical field [0001] The invention relates to a double needle bed electronic jacquard warp knitting machine. Background technique [0002] Double needle bed electronic jacquard warp knitting machine includes loop forming device, bar device and transmission device.

AI Technical Summary

Problems solved by technology

And in the double-needle bed warp knitting machine, the above-mentioned transmission mechanisms generally adopt a cam mechanism, or a combined transmission of a cam or a cam and an eccentric wheel mechanism. The relevant transmission disclosed in the publication specification of the invention patent application for the swing position adjustment device of the guide bar in the warp knitting machine adopts a cam transmission. Since the cam and the follower are in line or point contact, the pressure is strong, Easy to wear, not suitable for high speed, and difficult to process and manufacture, low precision
