Description

Technical Field

[0001] The invention relates to a needle plate and knitting needle combination structure for a flat knitting machine, and is particularly suitable for a needle plate structure of a flat knitting machine for full-molded knitting, and has practical significance for the development of ultra-fine needle gauges. 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 with a base plate, which is mainly used to produce fully-formed high-end products. Sweater manufacturers use ordinary two-needle plate flat knitting machines to achieve 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 line are high, which cannot achieve the overall effect of the sweater knitted by the normal needle gauge. The development of high machine gauge is to meet the needs of cashmere sweaters and high-end T-shirts. The production needs; the inquiry of a published needle plate needle combination and needle selection mechanism for a flat knitting machine (patent number is CN 111334923), although it has advantages over the alternate needle, the existing patent technology analysis shows that the needle output is unstable, which is easy to cause fine needles. The rear end of the one-slot double needle adopts the method of controlling the needle clock switching, which has a complex structure. The complex structure is prone to occasional loss of control in actual operation, resulting in quality problems of the grey cloth. The method of controlling the needle clock switching requires the running machine head to move out of the weaving area when doing full-bed knitting, which greatly delays the production efficiency of knitting. The needle plate insert (commonly known as the needle plate insert) structural parts analysis of its structure is difficult to process, the insert cost is high, the insert is installed in large numbers on the needle plate, and the cost of the needle plate assembly is greatly increased. In order to overcome the disadvantages of the above-mentioned patent (CN 111334923), it is necessary to continuously improve and study the existing flat knitting machine needle plate needle combination structure, and design a needle plate needle combination structure that is simple in structure and low in cost, stable in turning needle output, and can improve the knitting efficiency.
