Wool yarn looping auxiliary device of circular knitting loom and wool top knitting loom provided with the wool yarn looping auxiliary device

Abstract

The invention discloses a wool yarn looping auxiliary device of a circular knitting loom, which comprises a wool yarn looping auxiliary plate, a position adjusting block of the wool yarn looping auxiliary plate and an adjusting base, wherein the wool yarn looping auxiliary plate is an irregular polygon plate provided with a knife, the adjusting block is a strip plate and the adjusting base is an L-shaped plate with rectangular cross section. The invention further discloses a wool top knitting loom provided with the wool yarn looping auxiliary device of the circular knitting loom, comprising upper and lower cylinders provided with a needle groove on each of the cylinders, an upper needle in the needle groove of the upper cylinder and a positive bearded needle in the needle groove of the lower cylinder. When using, the wool yarn looping auxiliary plate is located outside the opening of the upper cylinder and on the reverse side of the positive bearded needle, and further the wool yarn looping auxiliary plate stands on the opening of the lower cylinder. According to the invention, the wool top knitting loom combines the functions of the wool yarn looping auxiliary device, the current positive bearded needle and a dummy slider, thereby increasing the stability of yarn feeding, knockover, looping and the like of the wool yarn and the effectiveness of the control after the wool yarn looping, and having a good effect of retaining the quality of the wool top fabrics and increasing the productivity under the condition of high feeders and rotating speed.

Description

technical field [0001] The invention relates to a top knitting machine accessory and a top knitting machine, in particular to a wool yarn loop forming auxiliary device for a circular knitting machine and a top knitting machine with the device. Background technique [0002] Existing top knitting machine is to use a kind of reverse crochet needle without needle latch, as Figure 8 As shown, the reverse crochet needle 3b does not have a latch, and the hook direction of the needle hook is on the same surface as the stitch pin and is in the opposite direction. The hook goes down to the center of the needle cylinder, when the yarn is fed, the hook of the anti-crocheting needle is inward and moves in the same direction as the upper knitting needle when it eats the yarn (see Figure 3-2 ), it is obvious that when feeding the yarn, it is easy to cause the anti-hooking needle or the upper knitting needle to fail to hook the yarn or the hooking yarn is unstable, which will cause qualit...

Problems solved by technology

[0002] Existing top knitting machine is to use a kind of reverse crochet needle without needle latch, as Figure 8 As shown, the reverse crochet needle 3b does not have a latch, and the hook direction of the needle hook is on the same surface as the stitch pin and is in the opposite direction. The hook goes down to the center of the needle cylinder, when the yarn is fed, the hook of the anti-crocheting needle is inward and moves in the same direction as the upper knitting needle when it eats the yarn (see Figure 3-2 ), it is obvious that when feeding the yarn, it is easy to cause the anti-hooking needle or the upper knitting needle to fail to hook the yarn or the hooking yarn is unstable, which will cause quality problems on the cloth surface; Figure 3-2 As shown, when the lower anti-hook knitting needle hooks the wool yarn and then forms a loop, the wool yarn is naturally unhooked to form a loop when the anti-hook knitting needle moves upward under the action of the triangle; because the wool yarn is a soft material, the anti-hook The upper and lower strokes of the knitting needle are very large, and sometimes the length of the wool is more than 40mm, that is to say, the stroke of the reverse hook knitting needle must reach more than 40mm. There are great limitations; therefore, in order to make up for the above two defects, the existing top knitting machines all adopt low speed, low number of paths and thick needles to reduce the cloth surface defects caused by the above defects; In order to complete the yarn feeding and knitting action of the knitting machine, the production efficiency of the top knitting machine is sacrificed.
