Abstract

The invention discloses a tensioning device. A sliding block of the tensioning device is provided with a slope with the inclination angle being adjustable. A guiding column is provided with a guiding part which extends out of a guiding sleeve and travels on the slope, so that the slope forces the guiding part to drive the guiding column to move vertically, and a tensioning wheel is driven to move. An equivalent elastic coefficient of a spring is changed by changing the inclination angle of the slope, thus, different tension ranges, namely the high range or the low range, are provided, and the defect that the spring fails and consequently the elastic coefficient is influenced can be overcome by adjusting the inclination angle; and changes of tensile caused by pressure changes between transmission rollers are adjusted through an adjusting mechanism, so that the tensile is basically kept constant.

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...

Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 and figure 2 As shown, the embodiment of the present invention discloses a tensioning device for providing tension to the cloth 15 between two pairs of driving rollers 14 . The tensioning device specifically includes: a mounting base 1, a guide sleeve 2, a guide column 3, a tensioning wheel 4, a slider 5, a first spring 19, a second spring 6 and an adjustment mechanism. The mounting seat 1 is fixed on the overall equipment for conveying the cloth 15, and is located below the cloth 15 between two pairs of drive rollers 14; the guide sleeve 2 is fixed vertically on the mounting seat 1, and along the axial direction of the guide sleeve 2 A vertical groove is set on the cover wall; the guide column 3 is arr...
