Weft insertion rapier driving device of medium speed rapier loom

Abstract

The invention relates to a weft insertion rapier driving device of a medium speed rapier loom. The weft insertion rapier driving device comprises a rapier tape guide rail, a rapier tape guider and a weft insertion guide rail. The rapier tape guider drives the rapier tape guide rail to drive a rapier, and the rapier tape guide rail drives the weft insertion guide rail to achieve weft insertion. According to the weft insertion rapier driving device, the defect of an existing rapier loom weft insertion technology is overcome; compared with the existing weft insertion technology, a rapier driving box is fixed, weft insertion loads are greatly reduced, and the energy-saving effect is achieved; during weft insertion, rapier head rapier tape can only move left and right and cannot swing back and forth, and abrasion is reduced; the number of weft insertion mechanical parts is smaller compared with an existing low-speed rapier loom, and the reliability is good; the weft insertion rapier driving device is in an open type, maintenance is convenient, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a weft insertion and sword transfer device for a medium-speed rapier loom, and belongs to the technical field of improvement of the weft insertion mechanism of a rapier loom. Background technique [0002] In the field of rapier looms today, there are two distinct types of rapier looms, one is a low-speed rapier loom with crankshaft beating-up and connecting rod weft insertion; the other is cam beating-up, or connecting rod, Or a cam, or a high-speed rapier loom with weft insertion by a propeller. Low-speed rapier looms are mainly 747 and 736 models, with a speed of 200 rpm and a price of less than 40,000 yuan; high-speed rapier looms are mainly imported with G6300, GT-MAX, and R88 Generally at 500 rpm, the price is generally more than 180,000 yuan, and the price of domestic imitation high-speed rapier looms is generally more than 150,000 yuan. [0003] The price difference between the above two types of rapier looms has reach...

AI Technical Summary

Problems solved by technology

The biggest defect is that the part of the sword transmission box has to swing back and forth together with the sley, which increases the load of weft beating and limits the speed increase of the loom

However, the weft insertion and transmission devices of high-speed rapier looms are all enclosed in the box. If they are fixed, either space connecting rods, cams, or propellers are used for weft insertion. The manufacturing accuracy and manufacturing cost are very high. The speed can be increased, but maintenance is very troublesome
