Example Embodiment

[0037] Example one

[0038] See attached picture. The compound needle in this embodiment includes a main needle 1 and a needle cover 2 sleeved on the main needle; the main needle 1 is elongated, and the head is provided with a hook 11, and the direction in which the hook is bent is now defined as On the right side, the opposite direction of the hook bending is defined as the left side, and the two planes of the main needle are defined as the front and back sides; below the hook, the right side of the main needle is provided with an outwardly protruding boss 12, opposite to its position The left side of the main needle is bent inward 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 A recessed containing groove 14 is used to place the top corner of the needle sleeve.

Example Embodiment

[0047] Example two

[0048] The composite needle in this embodiment includes a main needle and a needle sleeve sleeved on the main needle; the right side of the main needle is provided with an outwardly protruding boss, and the front and rear sides of the boss are provided with concave accommodating grooves. Place the top corner of the needle sleeve. The downwardly extending side of the boss is provided with convex points, and the needle sleeve is provided with an uneven track surface on the side facing the main needle. The track surface is composed of a plurality of smooth concave and convex surfaces. The convex points on the main needle and the needle sleeve The upper and lower track surfaces are in contact with each other, and the main needle can be provided with two upper and lower bumps. The two bumps are used to support the sliding of the needle sleeve under pressure, reducing the contact area, thereby reducing the friction, and facilitating the needle sleeve Smooth slidin...

[0049] Example three

[0050] The composite needle in this embodiment includes a main needle and a needle sleeve sleeved on the main needle; the right side of the main needle is provided with an outwardly protruding boss, and the front and rear sides of the boss are provided with concave accommodating grooves. Place the top corner of the needle sleeve. The downwardly extending side surface of the boss is provided with an undulating first track surface, and the side of the needle sleeve facing the main needle is provided with an undulating second track surface. Utilize the cooperation between the undulating first track surface on the main needle, the bumps on the main needle and the same undulating second track surface on the needle sleeve to change the distance between the needle sleeve and the main needle. When the top angle is at the position of the needle groove of the main needle, the distance between the two is the shortest. Then during the upward movement of the needle sle...

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...
