Description

A yarn feeder disc turning anti-twisting device for hosiery machine

technical field

The utility model relates to the technical field of knitting equipment, in particular to a yarn feeder disc overturning anti-thread entanglement device for a hosiery machine.

Background technique

With the continuous development of industrial automation technology, the field of sock knitting machine is gradually developing towards the direction of automatic sock toe sewing (sock knitting and toe toe integrated sock machine). When grabbing the socks to sew the toe in the automatic sewing head integrated sock machine, the yarn feeder disc must be lifted to make the grabbing device enter above the knitting needle cylinder of the sock machine. There are two existing techniques for lifting the yarn feeder disc. One is vertical lifting, and the other is turning up around an axis. During the upward turning of the yarn feeder disc, the yarn will be loosened or the yarn worn between the yarn feeder discs will be stretched. The former is turned up. During the process, the thread is tangled, and the latter is caused by the stretching and relaxation of the yarn when the yarn feeder is turned down to the initial position. At this time, it will cause yarn breakage when entering the next knitting cycle again. Thereby, the knitting efficiency and knitting yield of the hosiery machine are greatly reduced. So far, there has not been an effective solution to the problem of thread entanglement caused by the overturning of the yarn feeder disc, which restricts the development of the automatic sewing head integrated sock machine.
