Velveteen air jet loom

Abstract

The invention relates to a velveteen air jet loom. The velveteen air jet loom comprises a machine frame, a numerical control velveteen let-off mechanism, a velveteen shaft let-off mechanism, a bottom shaft let-off mechanism, a warp stop mechanism, an opening mechanism, a beating-up mechanism, an air jet weft insertion mechanism, a reeling mechanism, a batching mechanism and an electric control box. The velveteen shaft let-off mechanism lets pile warp off through the numerical control velveteen let-off mechanism, lets ground warp off through the bottom shaft let-off mechanism, the warp are conveyed into the air jet weft insertion mechanism from the opening mechanism through the warp stop mechanism, the air jet weft insertion mechanism is driven by the beating-up mechanism to complete weaving of double-layer velveteen, and then the double-layer velveteen is conveyed to a double-layer cutting mechanism, cut apart, and reeled through the reeling mechanism so as to be conveyed to the batching mechanism for collection.

Description

technical field [0001] The invention relates to a loom, in particular to a velveteen air-jet loom. Background technique [0002] Velveteen fabric is a relatively high-grade product among cotton fabrics and has broad market prospects. On the traditional velveteen loom, the change of the tight weft tension of weft beating occurs in an instant after the loose weft filling used to form the pile, which affects the pile quality of the pile warp yarn. The traditional rapier loom sets the leaf spring tension adjustment and the raising roller sequentially on the let-off route of the pile warp beam, but with the replacement of the air-jet loom, the pile warp yarn has a lower The resulting tension is different in the width direction of the leaf spring. The leaf spring is easily deformed after long-term high-speed use, which affects the tension control and leads to a decrease in weaving quality. [0003] Traditional velveteen looms mostly use vulgar rapier weft insertion, which has lo...
