Double-pulling cloth laying mechanism of protective clothing cloth laying machine

Abstract

The invention relates to the technical field of cloth laying machine equipment production, and discloses a double-pulling cloth laying mechanism of a protective clothing cloth laying machine. The mechanism comprises mounting racks symmetrically arranged on the cloth laying machine, the two mounting racks are respectively provided with a roll shaft I, a roll shaft II and a roll shaft III, and the roller shaft II exerts in negative pressure on the surface of the cloth, is blocked by the tension degree of the cloth and is kept at the station. According to the double-pulling cloth laying mechanism of the protective clothing cloth laying machine, an induction unit detects the change of the roller shaft II, drives a stepping motor on a self-locking transfer assembly to drive an eccentric wheel to rotate by a certain angle, and drives a connecting rod assembly to slide, so that the roller shaft I and the roller shaft III make a response, that is, the roller shaft I and the roller shaft III get close to each other or get away from each other, and the cloth tension degree is driven to change, the roller shaft II is reset, the purpose that the tensioning degree can be changed in a self-adaptive mode is achieved, and the problems that the cloth slipping phenomenon occurs and cloth is contaminated by engine oil or wrinkles or rolls are solved.

Description

technical field [0001] The invention relates to the technical field of fabric spreading machine production, in particular to a double-pull fabric spreading mechanism of a protective clothing fabric spreading machine. Background technique [0002] The cloth spreading machine is used in the cloth cutting industry to cut the cloth. Before cutting the cloth, it is necessary to lay the cloth on the cloth spreading table of the cloth spreading machine, and then the roller rotates at a preset speed under the control of the controller. Combined with the movement of the machine head, the cloth is laid down at the corresponding linear speed, and the cloth is laid flat on the spreading table. At present, the spreading methods adopted by spreading machines on the market mainly include single-draw spreading and double-draw spreading. [0003] According to the patent number CN201810003896.7, a double-pull spreading mechanism of a spreading machine is disclosed, which includes a base plat...

AI Technical Summary

Problems solved by technology

[0004] When operating the spreading machine with double pull to spread the cloth, since the spacing of multiple groups of cloth guide rollers is fixed, the actual thickness of the cloth produced is different, and the rollers on the rollers will be replaced due to the needs of production during the production process. Cloth roll, which makes it difficult to maintain the tension of the cloth when it passes through the cloth guide roller, resulting in the phenomenon of cloth slipping
