Yarn guide of textile machinery

Abstract

The invention discloses a yarn guide of textile machinery. The yarn guide of textile machinery structurally comprises two rollers, supports, a partition plate and yarn guide grooves, wherein the two rollers are fixed between the two supports in an up-down arrangement mode, the partition plate is installed at the bottom of the roller at the bottom layer, more than two yarn guide grooves are horizontally arranged on the partition plate, the yarn guide grooves are provided with air pumps, air devices, outer grooves and inner grooves, the air pumps are installed on the outer grooves, an installation cavity is arranged between each inner groove and the corresponding outer groove, layering separation grooves, exhaust grooves and an air guide port are arranged in each installation cavity throughthe corresponding air device, a yarn passing through each inner groove is stably fed in a state that the yarn does not contact with the inner wall of the groove by using gas generated by a plurality of densely-distributed bowl-shaped exhaust grooves, and the yarn is prevented from being damaged due to different degrees of abrasion generated in the yarn guide.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a textile machinery yarn guide. Background technique [0002] The yarn guide is an integral part of the flat knitting machine. When knitting on the flat knitting machine, the yarn to be knitted enters the needle hook of the knitting needle through the yarn guide for knitting. According to the different requirements of various braided fabrics, different yarn guide holes, such as one hole, two holes or three holes, are respectively set on a yarn guide to intersperse different yarn varieties, and then use the height of the holes to make different yarns The yarns are interwoven while weaving to meet the fabric design requirements. On the textile circular weft machine, the yarn guides usually used are made of hard tool steel. According to the speed and the friction of the yarns used, the yarn guides will Different degrees of wear. The "notch" on the yarn guide caused by the friction ...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a yarn guide for textile machinery to solve the problem that the commonly used yarn guide is made of hard tool steel. According to the speed and the friction of the yarn used, the yarn guide will produce different The degree of wear and tear. The "notch" on the yarn guide caused by the friction of the yarn will damage the yarn and reduce the quality of the fabric.
