Tension-free cloth storing frame

Abstract

The invention discloses a tension-free cloth storing frame which can lead a fabric which passes through the tension-free cloth storing frame to run in a tension-free way. The tension-free cloth storing frame comprises a main frame body, wherein a plurality of lower large cloth guide rollers and lower driving motors are respectively arranged on two sides at the lower end of the main frame body, a plurality of upper large cloth guide rollers and upper driving motors are evenly arranged at the upper end of the main frame body, a plurality of upper balance driving chain wheels are arranged among the adjoining upper large cloth guide rollers at the upper end of the main frame body, a plurality of lower balance driving chain wheels which are matched with the upper balance driving chain wheels are arranged at the lower end of the main frame body, a plurality of balance driving chains are arranged between the upper balance driving chain wheels and the lower balance driving chain wheels, a plurality of small cloth guide rollers are arranged on one side of each balance driving chain, the small cloth guide rollers are arranged in a plurality of driving roller guide grooves matched with the small cloth guide rollers, a plurality of bob-weight blocks matched with the small cloth guide rollers are arranged on the other sides of the balance driving chains, and a plurality of upper limiting sensors and lower limiting sensors, which are mutually matched with the small cloth guide rollers, are respectively arranged on the main frame body.

Description

technical field [0001] The invention relates to a cloth storage device, in particular to a tension-free cloth storage rack. Background technique [0002] In the textile post-processing industry, many processes such as fabric compounding and surface coating treatment require that the production process cannot be stopped and the fabric runs without tension, which requires the use of a cloth storage rack. There are many types of cloth storage racks used in traditional fabric compounding machines or coating machines, including those with magnetic powder to control the tension of the fabric, those with hydraulic cylinders to control the tension, and those with air cylinders to control the tension. The structure of these tension control mechanisms is complicated, and the produced fabrics often have edge curling and lamination after aging treatment, and the cost of these tension control mechanisms is relatively high, and the operation is inconvenient, especially the tension control...

AI Technical Summary

Problems solved by technology

The structure of these tension control mechanisms is complicated, and the produced fabrics often have edge curling and lamination after aging treatment, and the cost of these tension control mechanisms is relatively high, and the operation is inconvenient, especially the tension control must be adjusted according to the set value. Different from frequent adjustments and high labor intensity, it is impossible to run the fabric without tension, but can only run with constant tension, which cannot well meet the requirements of the production process
