Novel double-beam rapier loom

Abstract

The invention discloses a novel double-beam rapier loom. The novel double-beam rapier loom comprises a rack, a let-off mechanism, a beating-up mechanism, a driving system and a winding mechanism, wherein a left wallboard and a right wallboard are arranged on the rack, a heald frame mechanism is arranged behind the let-off mechanism, a first let-off beam is horizontally fixed on a beam seat, and two ends of a second let-off beam are fixed on a fixing device independent of the rack. According to the rapier loom, the second let-off beam is arranged below the first let-off beam in parallel through the fixing support independent of the rack, the first and second let-off beams are driven by an independent driving system, and a traditional press roll device is omitted, so that the operation and the inspection treatment by operators are more convenient, and in addition, the tension of the two let-off beams can be well controlled; and the thickness of the left wallboard is larger than that of the right wallboard, so that the instability of left and right gravity centers can be avoided. Compared with the prior art, the novel double-beam rapier loom also has the advantages of simple and reasonable structure, high production efficiency and good cloth cover quality.

Description

【Technical field】 [0001] The invention relates to the technical field of textile processing equipment, in particular to a novel double warp beam rapier loom. 【Background technique】 [0002] As shuttleless looms replace shuttle looms, rapier looms will become the main production machine for woven fabrics. In the single warp beam weaving process of the rapier loom, because some special products have different fabric structures and different structural process requirements, some warp yarns have fewer interweaving points, the weaving shrinks, and the tension is too small, resulting in a high warp breakage rate in this part of the warp yarn process. , roughness and other quality problems, in serious cases, the menopause sheet sinks and the machine cannot be produced. In view of this situation, by adopting double warp beam weaving, the warp yarns with too small tension are independently warped during warping, which effectively solves the above-mentioned problems. However, the str...

Problems solved by technology

In the single warp beam weaving process of the rapier loom, because some special products have different fabric structures and different structural process requirements, some warp yarns have fewer interweaving points, the weaving shrinks, and the tension is too small, resulting in a high warp breakage rate in this part of the warp yarn process. , roughness and other quality problems, in serious cases, the menopause sheet sinks and the machine cannot be produced. In view of this situation, by adopting double warp beam weaving, the warp yarns with too small tension are independently warped during warping, which effectively solves the above-mentioned problems. However, the structure of the let-off device of the rapier loom with double warp beams is relatively complicated at present, the operation of the loom is not stable enough, the tension between the two warp let-off beams cannot be controlled, and the production efficiency is low. For the second double warp beam still can not be effectively fixed
