Device assembly for loom with weft yarn untwisting function

Abstract

The invention discloses a device assembly for a loom with a weft yarn untwisting function, and relates to the technical field of various looms such as water jet looms, air jet looms and rapier looms.The device assembly comprises a bottom plate and an upright post fixedly connected onto the bottom plate, wherein a servo motor and a speed reducer are arranged on the bottom plate; an output shaft ofthe servo motor is fixedly connected with an input end of the speed reducer through a first transmission mechanism; a weft yarn support rod is arranged at the side surface of the upright post; a rotating shaft of the weft yarn support rod is rotationally connected with the upright post; the output end of the speed reducer is installed and connected with the rotating shaft of the weft yarn supportrod through a second transmission mechanism; the positive and reverse rotation on-off operation of the servo motor is controlled so that the servo motor rotates in a reverse direction; therefore theweft yarn support rod rotates in the reverse direction, so that the weft yarn untwisting function is achieved. After the twisting degree of the weft yarn is reduced, weft yarns enter the fabric; the cloth surface can be smoother. The device assembly solves the problem that most weft yarns are not flat when entering into the fabric. The weaving effect is better.

Description

technical field [0001] The invention relates to the technical fields of various looms such as water-jet looms, air-jet looms, and rapier looms, in particular to a device assembly for looms with the function of untwisting weft yarns. Background technique [0002] The looms traditionally used for weaving with yarn can be divided into two broad categories: weaving and knitting. Machine looms include original shuttle looms and new shuttleless looms, and shuttleless looms mainly include rapier looms, air-jet looms, water-jet looms and projectile looms. Knitting machines are divided into two categories: warp knitting and weft knitting, and there are many subcategories under them. In the knitting category, the product development of China's weaving machinery is uneven. Among them, circular knitting machines and warp knitting machines develop rapidly, flat knitting machines and hosiery machines develop relatively slowly, and crochet machines develop rapidly. Domestic circular knit...

AI Technical Summary

Problems solved by technology

[0003] The existing device assembly for moving the weft yarn of the loom can only move the weft yarn toward the forward direction, but cannot make the weft yarn retreat to untwist, so the weft yarn is not smooth enough after entering the fabric, The cloth surface is not smooth enough, which reduces the quality of the product
