Multilayer cloth multi-shed water jet loom

Abstract

The invention relates to a multilayer cloth multi-shed water jet loom, which comprises a front rack and a rear rack, wherein a multi-arm mechanism is arranged above the front rack, a heald frame assembly controlled by the multi-arm mechanism is arranged below the front rack, the left side of the front rack is provided with a weft insertion mechanism, and the rear part of the front rack is provided with a ground warp weaving shaft; and a seam warp weaving shaft and a tension compensating device are arranged on the rear rack. The multi-arm mechanism enables warps passing through harness wires in a seam warp heald frame to form six warp positions and five sheds; the weft insertion mechanism can simultaneously jet five wefts in the five sheds up and down, and multilayer cloth of less than or equal to five layers can be woven by weft insertion and battening; and the seam warp weaving shaft and the tension compensating device enable seam warps to be conveyed at a constant speed and subjected to seam warp tension compensation in a single seam warp heald frame so as to meet weaving of the multilayer cloth of less than or equal to five layers with a comparatively complex tissue structure. The multilayer cloth multi-shed water jet loom has the advantages of doubled production efficiency, production variety increment, wide application and the like.

Description

technical field [0001] The invention relates to a textile machine, in particular to a water-jet loom with multiple layers of cloth and multiple sheds. Background technique [0002] Today's looms, whether they are shuttles in the past or modern shuttleless looms, are mostly single-shed looms, that is, the warp has only two positions, the upper and the lower, to form a shed, and the weft is drawn from a shed or a single shed. Or a few or changing colors or changing counts or changing materials through the "single shuttle box", "single jet" and so on, passing through one by one weft by weft, and weaving into the required weaving through weft insertion and weft beating. cloth. When a multi-layer fabric with more than two layers is required, such as velvet, two sheds are required, and the warp yarn needs three positions in the upper, middle, and lower positions; while five-layer industrial fabrics need to form five sheds, and the warp yarn needs to be in six upper and lower posi...

AI Technical Summary

Problems solved by technology

When a multi-layer fabric with more than two layers is required, such as velvet, two sheds are required, and the warp yarn needs three positions in the upper, middle, and lower positions; while five-layer industrial fabrics need to form five sheds, and the warp yarn needs to be in six upper and lower positions. , the existing single shed loom can only weave one weft yarn and one weft yarn in turn in a shed formed by changing positions of warp yarns from top to bottom and from bottom to top, which has low efficiency, poor quality and few varieties. Simpler style

And foreign countries have successfully developed and produced a double-shed rapier loom, which can weave double-layer cloth such as velvet. The warp can have three positions, upper, middle and lower to form two sheds. Double rapier loom inserts and beats up two weft yarns in the upper and lower sheds at the same time, but the price is very expensive, which is 50 to 100 times the price of ordinary shuttleless single shed looms

At the same time, there is no weaving machine that can have more than three sheds up and down, and the warp yarn can have more than four sheds with more than four warp positions up and down.
