Constant-tension cloth containing device

Abstract

The invention relates to a cloth containing device, in particular to a constant-tension cloth containing device which mainly comprises a shell, a track, a displacement sensor, a fixed lateral plate, a movable lateral plate and a travel switch. A group of fixed guide rollers which are installed side by side are installed on the fixed lateral plate and located on the upper portion of the inner portion of the shell, a group of movable guide rollers which are installed side by side are arranged on the movable lateral plate and located on the upper portion of the inner portion of the shell, the track is arranged between the center of the fixed lateral plate and the center of the movable lateral plate, the two ends of the track are welded to the fixed lateral plate and the bottom of the shell respectively, the movable lateral plate is in sliding connection with the track, and the fixed lateral plate is connected with the movable lateral plate through a spring. The constant-tension cloth containing device is simple in structure and convenient to install, can effectively achieve tension control over cloth or films, provides enough end connecting time and enough seam connecting time for a prior process, and therefore the phenomena that the cloth or the films are wrinkled and the films are thinned through tension or snapped due to the fact that tension control is unstable are avoided.

Description

technical field [0001] The invention relates to a cloth holding device, more specifically, to a constant tension cloth holding device. Background technique [0002] In the past, in the composite geomembrane production line using the thermal composite process, the tension control of the upper cloth and the membrane during the composite process was either too large or too small. If the tension of the membrane is too high, it is easy to cause the membrane to be broken; if the tension of the membrane is too small, it is easy to cause wrinkles in the membrane, which seriously affects the product quality and later construction. Therefore, the tension control of the upper cloth and the film during lamination has become a key technical problem that needs to be solved urgently. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a constant tension cloth holding device. This device is mainly u...
