Cloth tensioning mechanism

Abstract

The invention relates to a cloth tensioning mechanism. The cloth tensioning mechanism comprises a first chain wheel set, a second chain wheel set, a guide chain wheel set, chains and chain plates; the first chain wheel set and the second chain wheel set are arranged in a spaced mode; the chains surround the first chain wheel set and the second chain wheel set by a circle in a closed mode; each chain comprises a first chain part and a second chain part, and the guide chain wheel set is located on the first chain parts; each first chain part comprises a cloth pressing part and a cloth tensioning part, and the guide chain wheel set is located at the connecting positions of the cloth pressing parts and the corresponding cloth tensioning parts; and the number of the chains is at least two, the chain plates are located between the chains, the two ends of the chain plates are fixedly connected with the corresponding chains, and a clamping assembly is arranged on each chain plate. According to the mechanism, the cloth can be tensioned in the width direction, the problem that the cloth cannot be continuously stretched in the width direction in the cloth advancing process in the prior art is solved, the tensioning efficiency is improved, and the cloth quality is improved.

Description

technical field [0001] The invention belongs to the technical field of cloth production equipment, and relates to a cloth tensioning mechanism. Background technique [0002] my country's textile industry has generally adopted automated textile machinery. The fabric is stretched by the tensioning mechanism and then cut by the cloth cutting machine. The cut fabric must be smooth and coherent to ensure the quality of the product after the remaining processes. The tensioning mechanism of the existing cutting machine only realizes the tensioning of the cloth through the tensioning assembly composed of the cylinder and the roller body. In the fabric production process, it is generally guided to another step or rolled up by pulling. When pulling, the existing technology mostly uses stretching in the length direction of the fabric. Since the fabric itself is criss-crossed Weaving, therefore, during the pulling process, the length direction of the cloth pulling will be relatively el...

Problems solved by technology

The cloth passes through the support roller and the opening roller in turn, and the opening roller drives it to rotate through the driving mechanism. At this time, the opening pattern of the spiral structure opens the cloth to the edge direction, so as to achieve the purpose of allowing the cloth to open, so that the cloth When stretching, the two sides of the fabric will not shrink too much. In addition, the open pattern will be extended to both ends in the opposite direction, so that the fabrics on both sides can be opened, so that the degree of fabric shrinkage inward is reduced. Small, so that the overall width of the cloth remains basically unchanged, but in the process of opening the cloth by the opening roller in this device, the cloth is spread horizontally by using the rotation direction of the opening pattern on the opening roller, and the gap between the opening pattern and the cloth There will be friction between them, causing the local temperature of the fabric to heat up rapidly, affecting the quality of the fabric
