Velvet loom with flexible large rapier

Abstract

The invention provides a velvet loom with a flexible large rapier, and belongs to the technical field of textile machinery. A uniform acceleration heald lifting opening device is designed and manufactured according to the special curve principle of an eccentric cam; in a picking and beating-up device, a flexible rapier belt reciprocates to enable a rapier head to receive and send wefts so as to complete picking motion; the cross section, entering a shed part, of the flexible rapier belt is in a slightly-protruding arc shape; the reciprocating motion of the flexible rapier belt is completed by driving a chain hole in the rapier belt through a chain wheel of a rapier transmission gear box of the rapier loom; and devices capable of adjusting front-back swinging and left-right lifting are arranged on bases at the two ends of a linear guide rail of a velvet cutting device for velvet. The velvet loom not only solves the key problem that a double-layer double-shed double-rapier velvet loom cannot weave thin velvet, but also can break through the problem that the double-layer double-shed double-rapier velvet cutting surface is single, and also solves the problems that a single-layer single-shed shuttle velvet loom is low in yield and poor in quality and a weft winding process is added.

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.
