Fixing mode of jacquard shift needle

Abstract

The invention discloses a fixing mode of a jacquard weave shifting needle used for a tricot machine; a groove 4 and a groove 6 which are equally spaced in a group are respectively arranged at the upper end and the lower end of a needle seat 1, the section of a needle chip carrier 3 is a tabular shape, needle bars 7 of a needle chip 2 are respectively embedded into the groove 4 and the groove 6 that are arranged at the upper end and the lower end of the needle seat 1, the needle chip carrier 3 protrudes outside the groove 4 arranged at the upper end of the needle seat 1, the adjacent left and right needle chip carriers 3 are closely matched with each other, the needle chip 2 can be reliably fixed only by gelatinizing on the sides of the needle chip carriers 3, and the needle chip 2 can be replaced only by removing the glue on sides of the needle chip carriers 3; as glue-spread is less, the glue can be conveniently removed, and the needle chip 2 can be easily replaced. Therefore, single needle chip can be exchanged without replacing the components of the needle chip 2 and the needle seat 1, and the using cost can be greatly reduced.

Description

technical field [0001] The invention relates to a fixing method of a jacquard displacement needle, in particular to a fixing method of a jacquard displacement needle used in a warp knitting machine, and belongs to the field of knitting machinery. Background technique [0002] The jacquard shifting needles on the warp knitting machine are installed on the needle base, and at least one set of jacquard shifting needle needles with more than 2 pieces can be installed on one needle base. There are 8, 12, and 16 pieces in each group on the existing market. piece, 24 pieces, etc., there are corresponding slots on the needle seat for installing needle pieces and switch wires. At present, after the needle pieces of the jacquard shifting needle are installed on the needle base, there is a large gap between the adjacent left and right needle pieces carriers, and the needle pieces are fixed by applying glue to the gap, and formed in this group of needle pieces. Continue to apply glue o...

AI Technical Summary

Problems solved by technology

At present, after the needle pieces of the jacquard shifting needle are installed on the needle base, there is a large gap between the adjacent left and right needle pieces carriers, and the needle pieces are fixed by applying glue to the gap, and formed in this group of needle pieces. Continue to apply glue on the surface of the needle to further fix it, so that a firm bond is formed between the needle pieces. This kind of fixing method makes it difficult to take out the damaged needle piece as long as one piece is damaged. If you want to take it out, it will damage the adjacent needle piece. The pins and lines between the left and right cannot be replaced by a single pin, that is, a single pin is not interchangeable, and this group of components containing multiple pins and needle seats can only be scrapped at the same time and replaced. A complete set of needle blade and needle seat assembly

At present, the value of such a set of needle pieces and needle holders on the market is several thousand yuan, and a warp knitting machine generally has 100 to 200 sets of needle pieces and needle holders. The problem of damage, but the entire needle piece and needle seat assembly is scrapped just because of the damage of one needle piece, which has caused huge waste, resulting in high costs for enterprises to use warp knitting machines, directly affecting the economic benefits of production enterprises
