Tensioning device

Abstract

The invention discloses a tensioning device. The tensioning device comprises a mounting base, a guide sleeve, a guide post, a tensioning wheel, a sliding block and a spring. The mounting base is used for being mounted on body equipment. The guide sleeve is vertically arranged on the mounting base. The guide post is arranged inside the guide sleeve and can move vertically along the guide sleeve. The tensioning wheel is arranged on the guide post and used for making contact with cloth. The sliding block is used for sliding horizontally on the mounting base to get close to or keep away from the guide sleeve. The spring is horizontally arranged to abut against the sliding block in the direction towards the guide sleeve. The sliding block is provided with an oblique plane with the angle of inclination capable of being adjusted. The guide post is provided with a guide part which stretches out of the guide sleeve and travels on the oblique plane, so that the oblique plane forces the guide part to drive the guide post to move vertically. According to the tensioning device, the equivalent elasticity coefficient of the spring can be changed by changing the angle of inclination of the oblique plane, and thus different tension ranges including the high range or the low range can be provided; and moreover, the influence on the elasticity coefficient due to failure of the spring can be reduced by adjusting the angle of inclination.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a tensioning device. Background technique [0002] In the field of textile technology, when the cloth is sorted into rolls, the cloth is generally conveyed on multiple pairs of drive rollers arranged at intervals. Specifically, the cloth is clamped between a pair of driving rollers, so that a certain frictional force is generated between the cloth and the driving rollers, so that the cloth is conveyed by the driving rollers. In order to make the cloth have a certain tension during the conveying process so that the cloth has a certain density after being rolled, usually, a tensioning mechanism is arranged between the two pairs of driving rollers, and the tensioning mechanism causes the cloth to generate a certain tension. [0003] In the prior art, the tensioning mechanism for tensioning the cloth includes a tensioning wheel for abutting against the cloth and for pushing against...

Problems solved by technology

A more prominent disadvantage of this structure is that due to the repeated use of the spring, the spring will fail due to fatigue, so that its elastic coefficient will decrease, and eventually it will not be able to provide enough tension for the cloth, which will affect the density of the cloth after it is rolled.
