Description

  The present invention relates to a mechanism of a circular knitting machine and parts thereof, and more particularly to a mechanism and a sinker that are applied to a circular knitting machine to assist loop knitting and detachment from a cylinder.

  As is clearly shown in FIGS. 1 and 2, the known loop knitting cylinder disengaging mechanism technology of the circular knitting machine is a cylinder 4a in which a knitting needle 5a is vertically disposed in the loop knitting cylinder disengaging mechanism 1a in the drawings. A plurality of correction grooves 41 are always provided above the cylinder 4a. Further, a sinker board 10a is provided on the outer edge of the cylinder 4a, and a plurality of sinker grooves 11a are horizontally arranged. A sinker 3a is arranged on each sinker groove 11a, and a plurality of guide bodies 20a are provided above the sinker 3a. Arranged, the guide body 20a follows the sinker 3a and reciprocates it. Among them, the sinker 3a includes a slide area 31a, and the slide area 31a includes a slide portion 310a that slides in the sinker groove 11a. The loop knitting cylinder disengagement auxiliary area 32a extends upward from one side of the slide portion 310a and then extends outward. In the loop knitting cylinder disengagement auxiliary area 32a, the knitting needle 5a knitting a loop and disengages from the cylinder. A thread pressing groove 320a having a shape recessed inward in a horizontal state for assisting is formed. The driven area 30a positioned above the slide area 31a and driven by the guide body 20a includes a protruding portion 300a extending upward from the slide portion 310a. The correction area 34 formed by extending downward from the loop knitting cylinder separation assist area 32a is inserted into the correction groove 41, and the knitting needle 5a knitting the loop under the restriction of the correction groove 41. It accurately assists withdrawing from the cylinder. Thereby, when the sinker 3a performs a reciprocating flat movement, the left side surface, the right side surface, and the bottom surface of the correction area 34 are necessarily limited to the correction groove 41, and three-surface contact friction occurs in the correction groove 41. To do.

As described above, although the known technique has a function of assisting loop knitting of the knitting needle and cylinder detachment, the following drawbacks still exist in practice.
(1) About the loop knitting cylinder detachment mechanism 1a and the sinker 3a of a known circular knitting machine. Since the sinker 3a includes the correction area 34, the complexity and difficulty in the machining process are increased on the structure of the cylinder 4a. Therefore, the quality and yield of the cylinder 4a are greatly reduced, and intangible materials and personnel costs are increased.
(2) About the loop knitting cylinder disengaging mechanism 1a and the sinker 3a of a known circular knitting machine. Since the sinker 3a has the correction area 34, the correction area 34 inevitably continues to reciprocate in the correction groove 41 provided in the cylinder 4a and repeats frictional contact while the sinker 3a repeats reciprocating flat movement. As a result, there arises a problem in the sinker 3a that the temperature becomes high due to long-term friction and the temperature cannot be lowered. Further, if the sinker 3a continues to work for a long time in a high temperature environment, it causes extreme wear, deformation or damage, and greatly affects the service life of the sinker 3a. In addition, the load amount of electric power is increased, the effectiveness of the loop knitting cylinder disengaging mechanism 1a is impaired, and the entire environmental pollution problem is caused.
