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

Embodiment 1

[0038]See attached picture. The compound needle described in this embodiment includes a main needle 1 and a needle sheath 2 fitted on the main needle; the main needle 1 is elongated and has a needle hook 11 on the head, and the bending direction of the needle hook is now defined as On the right side, the opposite direction of the needle hook bending is defined as the left side, and the two planes of the main needle are defined as the front and rear sides; under the needle hook, there is an outwardly protruding boss 12 on the right side of the main needle, opposite to it The left side of the main needle bends inwardly to form a concave avoidance groove 13, so that the size of the coil sliding range on the main needle is kept within a certain range, which is convenient for the movement of the coil on the main needle; the front and rear sides of the boss are provided with There is a recessed accommodating groove 14 for placing the top corner of the needle cover.

Embodiment 2

[0048] The compound needle described in this embodiment includes a main needle and a needle cover set on the main needle; an outwardly protruding boss is provided on the right side of the main needle; to place the top corner of the socket. There are convex points on the side of the convex platform extending downward, and the side of the needle sleeve facing the main needle is provided with an undulating track surface. The track surface is composed of a plurality of smooth concave-convex surfaces. The upper and lower track surfaces are in contact with each other, and two convex points can be set on the main needle. The two convex points are used to support the sliding of the needle sleeve under pressure, which reduces the contact area, thereby reducing the friction force and facilitating the needle sleeve. Smooth sliding in the needle groove. The track surface of the needle cover is located on the side of the middle piece facing the main needle. The track surface is undulating...

Embodiment 3

[0050] The compound needle described in this embodiment includes a main needle and a needle cover set on the main needle; an outwardly protruding boss is provided on the right side of the main needle; to place the top corner of the socket. An undulating first track surface is provided on the side extending downward of the boss, and an undulating second track surface is provided on the side of the needle sleeve facing the main needle. The distance between the needle sleeve and the main needle can be changed by using the mutual cooperation between the undulating first track surface on the main needle, the bump on the main needle and the second undulating track surface on the needle sleeve. The distance between the two is the shortest when the apex angle is at the position of the needle groove of the main needle, and then during the upward movement of the needle sleeve, as the protruding positions of the first track surface and the second track surface are opposite, the distance ...

Abstract

The invention discloses a compound needle in a flat knitting machine. The compound needle comprises a main needle and a needle sleeve which sleeves the main needle; the main needle is thin and long, and the head of the main needle is provided with a needle hook; a top angle is arranged on the top of the needle sleeve, the side, facing the main needle, of the needle sleeve is provided with a firstbuckling member and a second buckling member, first concave faces and second concave faces are arranged on the upper sections of front and rear side faces of the main needle respectively, and the first buckling member and the second buckling member are buckled on the first and second concave faces; the side face, facing the needle sleeve, of the main needle cooperatively abuts against the side face, facing the main needle, of the needle sleeve to allow the top angle to move to the needle hook of the sealed main needle from an accommodation groove of the main needle when the needle sleeve moves. The knock-over resistance of a thread on the compound needle is small, the loop withdrawal stroke is short, the knitting speed is fast, a knitting needle at an opposite position can be guided into aneedle turning position, needle turning is reliable, the motion is simple and brief, the compound needle can smoothly slide in the needle groove, and a cloth surface is flat.

Description

technical field [0001] The invention belongs to the technical field of knitting machinery, in particular to a compound needle in a flat knitting machine. 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 down str...
