Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a geomembrane cutting device for preventing a film roll from deflecting. Background Art

[0002] Geomembrane is a geotechnical anti-seepage material made of plastic film as the anti-seepage base material and composited with non-woven fabric. The anti-seepage performance of the new material geomembrane mainly depends on the anti-seepage performance of the plastic film. The main principle of geomembrane is to use the impermeability of plastic film to block the leakage channel of earth dam, and to withstand water pressure and adapt to the deformation of dam body with its large tensile strength and elongation. In the process of using geomembrane, it is necessary to use a cutting device to cut it.

[0003] Publication No. CN217072490U discloses a geomembrane cutting device, including a base, a replacement structure and a geomembrane roll, a cutting assembly is installed on the upper surface of the base, a replacement structure is provided on the upper surface of the base, the replacement structure includes two fixed plates, the lower surfaces of the two fixed plates are fixedly connected to the base, the surfaces of the two fixed plates are slidably inserted with pull rods, the ends of the two pull rods away from each other are fixedly connected with handles, the ends of the pull rods away from the handles are fixedly connected with circular plates, the ends of the circular plates away from the pull rods are fixedly connected with clamping rods, and the arc surface of the clamping rod is clamped with a geomembrane roll. Although the device solves the problem that the replacement of the geomembrane roll of the traditional geomembrane cutting device is relatively cumbersome, the operator needs to spend a lot of time to replace it, which not only delays time, but also reduces the efficiency of geomembrane cutting, but the device does not have a limiting structure, which is easy to cause displacement in the process of cutting the geomembrane roll, thereby affecting the accuracy of geomembrane cutting, increasing the use cost of geomembrane, and inconvenient to use the cutting device, so it needs to be improved.
