A velvet loom with flexible large rapier

Abstract

The invention provides a velvet loom with a large flexible rapier, which belongs to the technical field of textile machinery. Its uniformly accelerated heald shedding device is designed according to the special curve principle of the eccentric cam. In its picking and beating-up device, there is a flexible sword belt reciprocating to connect and send the weft to complete the picking movement. The cross-section of the flexible sword belt has a slightly convex arc shape when entering the shed. The reciprocating motion of the flexible sword belt is driven by the sprocket of the sword transmission gear box of the rapier loom. The chain hole in the belt is completed, and the base at the two ends of the linear guide rail of the velvet cutting velvet device has an adjustable device for swinging back and forth, left and right, and up and down. The invention not only solves the key problem that the double-layer, double-shed, double-rapier velvet loom cannot weave thin velvet, but also breaks through the problem of single layer, double-shed, double-rapier cut velvet, and solves the problem of single-layer, single-shuttle At the beginning, there are problems of low output, poor quality, and one more weft-rolling process of shuttle velvet looms.

Description

technical field [0001] The invention relates to a textile machine, in particular to a velvet loom with a large flexible rapier. Background technique [0002] Now velvet looms are in a state of polarization. The advanced ones are double-layer double-shed double-rapier velvet looms, but most of them are produced by Van de Weel in Belgium, and the price is very expensive. The looms are only suitable for weaving medium-weight and heavy-weight velvets. They occupy a large area and have been developed by several factories in China. However, single-layer single-shed velvet looms with shuttles are still thriving now. One is that they are cheap, and the other is that they can weave thin velvets that are difficult to weave with double rapiers, and they occupy a small area. Their common feature is that there is a velvet feeding device necessary for weaving velvet, and the shed channel is clean and free of obstacles. The difference between them is that the double rapier loom weaves th...

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of velvet loom with flexible large rapier, because it is a velvet loom with single-layer single-shed flexible large rapier, which solves the problem of double-layer double-shed double rapier velvet loom. The key problem of weaving thin velvet can also break through the problem of single layer, double shed, double rapier cut velvet surface, and solve the problem of low output, poor quality, and one more weft roll of single layer single shed shuttle velvet loom The problem of the process, and the price is low, which makes up for the blank of the middle-grade velvet loom, and is very popular in the market.
