High-speed magnetic suspension type driving Jacquard knitting needle circular weft knitting machine

Abstract

The invention provides a high-speed magnetic suspension type driving Jacquard knitting needle circular weft knitting machine, which is characterized by comprising a machine frame, a transmission system, a large table top, a conducting sliding ring, a needle tube device and a sinker assembly, wherein the large table top is arranged on the machine frame, the transmission system is fixedly arranged on the large table top, the needle tube device is fixedly arranged on an output gear of the transmission system, a sinker ring of the sinker assembly is fixedly arranged on the needle tube device, a triangular ring of the sinker of the sinker assembly is fixedly arranged on the large table top through support feet, the annular needle tube device is of a split structure and consists of a plurality of needle tube components, dense magnetic suspension type driving knitting needles are distributed in the needle tube device, and are distributed in three circles including the inner circle, the middle circle and the outer circle, the angle between the two adjacent knitting needles on the middle circle are divided into three equal parts by the inner and outer knitting needles, the uniform space of the knitting needles is ensured, and the conducting sliding ring is arranged on the large table top. The high-speed magnetic suspension type driving Jacquard knitting needle circular weft knitting machine has the advantages that the contact and the friction are avoided in the suspension knitting needle movement, the efficiency is high, the reaction speed of the knitting needles driven in a magnetic suspension type driving mode is high, the needle selection frequency is high, the precision requirement of the mechanical processing is greatly reduced through the split structure, and in addition, the assembly and the maintenance are convenient.

Description

technical field [0001] The invention relates to a novel knitting jacquard weft circular machine and an electronic needle selection device for magnetic levitation driven knitting needles, in particular to a structural device for multiple magnetic levitation driven knitting needles. technical background [0002] The development of knitting machinery in our country is relatively slow, and the core device technology in knitting machinery has not been broken through. The needle selection driving method of the traditional knitting jacquard circular weft machine is to realize the specific motion track of the jacquard knitting needle ("three positions") through mechanical multi-stage transmission (triangular cam, knitting needle, needle jack, jacquard piece, etc.) , but because the existing knitting jacquard machine adopts the friction and wear of the mutual moving parts of the multi-stage mechanical mechanism, the impact of the knitting needle in the cam (cam), etc., seriously rest...
