Compound needle for flat knitting machine

Abstract

The invention discloses a compound needle for a flat knitting machine. The compound needle comprises a main needle and a needle sleeve mounted on the main needle in a sleeving mode; the main needle isin a long and thin shape, and a needle hook is arranged at the head of the main needle; a top corner is arranged at the top end of the needle sleeve, the side, facing the main needle, of the needlesleeve is of an open groove structure, the front side face and the rear side face of the main needle are sunken inwards to form concave faces, and the needle sleeve is clamped onto the concave faces of the main needle through an open groove; and a salient point is arranged on one of the side face, facing the needle sleeve, of the main needle and the side face, facing the main needle, of the needlesleeve, a track face is arranged on the other one of the side face, facing the needle sleeve, of the main needle and the side face, facing the main needle, of the needle sleeve, the salient point ismatched with the track face, and thus when the needle sleeve moves, the top corner moves to the needle hook for closing the main needle from an accommodating groove of the main needle. The compound needle is small in knockover resistance, small in knockover stroke and high in weaving speed; a knitting needle at the relative position can be guided to enter the needle overturning position, needle overturning is reliable, and the action is simple; and the compound needle smoothly slides in a needle groove, and a cloth cover is flat.

Description

technical field [0001] The invention belongs to the technical field of knitting machinery, in particular to a compound needle used for flat knitting machines. Background technique [0002] At present, the use of compound needles on flat knitting machines is becoming more and more common. Better actions can be achieved through the mutual cooperation of various components in the compound needles, but the structure is complex, which increases the processing difficulty to a certain extent, increases the scrap rate, and increases Cost of production. The latch needle in the prior art has a rotatable latch on the needle bar. Through the opening and closing of the latch, it cooperates with the main needle and the yarn to complete the loop forming, stripping, tucking and unlooping of the loop latch. , transfer, stitching and other actions, because the latch rotation requires space, the main needle transfer is provided with a reed, so that this kind of needle needs a large up and dow...

AI Technical Summary

Problems solved by technology

However, the structure of the main needle is too complicated, and the processing accuracy of the main needle and the needle sleeve is high.

At the same time, the top angle of the needle sleeve is inclined towards the main needle, so that when the top angle closes the needle hook, the width of the closed part increases, so that the passed loop becomes larger, which affects the knitting effect
