Description

Technical Field

[0001] The invention relates to a needle plate assembly for a flat knitting machine. Background Art

[0002] The development trend of modern computer flat knitting machines is towards intelligence, fine needle gauge, high efficiency, multi-function and simplification. The guided type of computer flat knitting machines is still compact and has a base plate. It is mainly used to produce fully-formed high-end products. Sweater manufacturers use the ordinary two-needle plate flat knitting machine to make one-time garments, that is, the body, sleeves and collar are all knitted out at one time, which is also called fully-formed knitting. However, the needle gauge formed by the needle gauge cannot reach the standard needle gauge of ordinary flat knitting machines. The needle gauge increases exponentially, the arc between the coils is long, the density cannot be made tight, and the requirements for the knitting thread are high, which cannot achieve the whole sweater knitted with normal needle gauge. The overall effect requires that the needle plate needle pitch is getting smaller and smaller. The smaller the needle pitch, the knitting needle is subject to the "knitting" three-station (five-station or seven-station) process requirements. The knitting needle cannot "become smaller" indefinitely, otherwise it will affect the normal knitting requirements, which causes the inserts on the needle plate to "become thinner and thinner". The inserts are getting thinner and thinner. In actual use, the knitting needles under the action of the machine head triangle are easily damaged by unstable factors such as impact. It is necessary to design a non-rocking structure between the inserts to ensure the stability between the inserts, so as to stabilize the operation of the knitting needles; at the same time, the unstable swing of the sinker in the sinker groove and other problems must also be overcome.
