Sinker abrasion-resistant device for weaving machine

Abstract

The invention relates to the technical field of knitting machines, in particular to a sinker abrasion-resistant device for a weaving machine. A needle cylinder with the abrasion-resistant device comprises a needle cylinder, wherein a sinker through groove matched with a sinker plate at outer edge is molded on the top of needle cylinder; an annular groove is formed on the surface of the top of the needle cylinder; an abrasion-resistant steel wire is arranged in the groove; and the sinker is rubbed with the abrasion-resistant steel wire along the through groove in the process of reciprocating. Due to the adoption of the technical scheme, the annular groove is formed on the surface of the top of the needle cylinder with the through groove, and the annular abrasion-resistant steel wire is arranged in the groove so as to ensure that the surface hardness of the through groove and the hardness of the sinker are uniform. Usually, the hardness of the abrasion-resistant steel wire is higher than that of the sinker, so that the abrasion-resistant steel wire cannot be abraded for a long time. In addition, the sinker abrasion-resistant device can ensure that sinkers in the sinker plate groove can be more smoothly woven after adopting the technical scheme, ensures the quality of woven cloth and prolongs the service life of the needle cylinder and the sinker plate.

Description

Technical field: [0001] The invention relates to the technical field of knitting machines, in particular to a wear-resistant device for a squeegee of a knitting machine. Background technique: [0002] Circular knitting machines (or knitting machines) have a circular needle cylinder, see figure 1 As shown, the needle cylinder 1 is in the shape of a cylinder, and needle grooves 11 for accommodating knitting needles are evenly opened on its outer peripheral surface. Run up and down. The top of the syringe 1 is formed with a through groove 13 for matching with the green sheet 14 . [0003] On the outer side of the syringe 1 is provided a gram plate 15 for carrying the gram sheet 14, the upper end of the gram plate 15 is provided with a chute 151 for accommodating the gram sheet 14, and the chute 151 corresponds to the top of the syringe The through groove 13 is in a straight line. [0004] During work, when the knitting needle 12 runs up and down, the knitting needle hook ab...

AI Technical Summary

Problems solved by technology

[0007] 1. During the continuous reciprocating operation, the gram sheet will rub against the through groove on the top of the needle cylinder. The bottom of the through groove and the bottom surface of the knitting needle will be worn due to friction, resulting in errors in matching accuracy, which will affect the quality of the final cloth weaving , it is easy to cause uneven weaving density, wrinkling, and unevenness of the cloth surface

[0008] 2. Although the hardness of the syringe can be enhanced by heat treatment, the heat treatment process is complicated and the operation is troublesome, resulting in an increase in product cost

In addition, even if the needle cylinder is subjected to heat treatment to increase its hardness, the heat treatment of the needle cylinder is likely to cause deformation of the needle cylinder itself due to heat and cold shrinkage effects, which is not ideal
