Full-breadth cloth supporting device of rapier jacquard loom

Abstract

The invention discloses a full-breadth cloth supporting device of a rapier jacquard loom. The device includes a box body, a motor is fixedly connected to the outer wall of one side of the box body through bolts, a first leftward rotated lead screw is rotatably connected to one end of the motor through a rotating shaft, a first rightward rotated lead screw is welded to the end, away from the motor,of the first leftward rotated lead screw, and the first leftward rotated lead screw is screwed into a first extrusion base through a thread; a smooth roller is installed on the inner wall of one sideof the first extrusion base, and the first rightward rotated lead screw is screwed into a second extrusion base through a thread. On the one hand, a full-bread cloth is effectively flattened by a transverse tensile force generated when the smooth roller moves towards two sides, the problem that the full-breadth cloth is creased and folded during conveying is avoided, it is ensured that the full-breadth cloth stays at a smooth and straight state when entering the jacquard loom, and the quality of jacquard patterns is improved; on the other hand, through the transverse tensile force, transversevibration of a part of the full-breadth cloth can be offset to avoid broken picks of the full-breadth cloth.

Description

technical field [0001] The invention belongs to the technical field of jacquard looms, and in particular relates to a full-width fabric support device of a rapier jacquard loom. Background technique [0002] The jacquard loom is specially used to weave jacquard fabrics, which are large-scale patterns woven by jacquard machines. The number of warp yarns in the complete pattern weave ranges from a few hundred to as many as thousands. Jacquard is mostly based on one weave. And use another or several different organizations to show patterns on it, such as plain weave and satin weave. Sometimes warp and weft yarns of different colors can also be used to make the fabric present a large colorful pattern. [0003] In the Chinese patent with the patent number CN201410541579.2, the full-width cloth support device of the rapier jacquard loom is mentioned, which completely changes the existing left and right cloth support structures and only plays a limited role on the left and right s...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a full-width cloth support device for a rapier jacquard loom, so as to solve the problems that the full-width cloth is prone to wrinkles, folds and broken warp and weft when the full-width cloth support device of the above-mentioned rapier jacquard loom is in use. question
