Latch needle structure of a hosiery machine

Abstract

The invention is applied to the technical field of hosiery knitters and discloses a latch needle structure for a hosiery knitter. The latch needle structure comprises a needle hook, a needle bar connected with the needle hook, a needle latch pin arranged inside the needle bar as well as a needle latch which can vertically move, wherein a needle hole matched with the needle hook is formed in one end of the needle latch; the other end of the needle latch is connected with the needle latch pin; a shuttle plate is also arranged between the needle hook and the needle latch and comprises a fixed part, a flat plate part connected with the fixed part and a bent part which is downwards bent; a U-shaped groove is formed in the inner side of the connected part between the flat plate part and the bent part; the needle hook penetrates through the U-shaped groove and is matched with the flat plate part to form a self-locking structure of closed line holes. According to the latch needle structure provided by the invention, the structure is reasonable and the application range is wide; the technical problem that the hosiery knitter in the prior art cannot make subsequent response to the condition that the needle hook and the support are bonded is effectively solved; the integral quality of the knitted hosiery is guaranteed; the working efficiency of the hosiery knitter is improved, so that the improvement on the integrated performance and the market competitiveness of the hosiery knitter are facilitated.

Description

【Technical field】 [0001] The invention relates to a latch needle structure of a hosiery machine. 【Background technique】 [0002] The sock knitting machine works normally, the latch needle structure in the needle groove of the sock knitting machine cylinder runs up and down, the needle hook and the bracket form a closed-loop thread hole, under the action of gravity and inertia when the latch needle structure goes up, the thread hole is closed by the needle latch Open, the needle hook hooks back to pick up the knitting thread. When faced with the situation that the needle hook and the bracket are bonded due to unexpected conditions, and the needle latch is difficult to open the thread hole, the needle hook in the closed loop thread hole is difficult to hook the thread. This causes the sock to lack needles and threads, which affects the quality of the sock. 【Content of invention】 [0003] The purpose of the present invention is to overcome the shortcomings of the above-menti...
