[0002] Industrial filter cloth is a filtering medium woven from natural fibers and synthetic fibers, mainly used for solid-liquid separation and industrial dust removal. During the production process of industrial filter cloth, the filter cloth needs to be wound into a cylindrical shape for turnover and transportation, and the filter cloth roll needs to be cut into different width sizes;

[0003] Chinese utility model patent with application number: CN202322576736.0 (publication number: CN220746418U) proposes a filter cloth cutting device, including an L-shaped workbench, a support block is slidably arranged on the workbench, a turntable driven by a motor is arranged on the support block, clamping grooves are arranged at the upper and lower ends of the turntable, a second hydraulic cylinder is slidably arranged in the clamping groove, a cutting disc driven by a motor is arranged at the end of the second hydraulic cylinder, and an auxiliary pressure pipe corresponding to the support rod is arranged at the central position of the turntable;

[0004] Filter cloths of different specifications have different diameters. When using the above patent, the auxiliary pressure pipe is sleeved on the filter cloth roll to determine the length to be cut. For filter cloths with a smaller diameter, although the pressing block can press the filter cloth roll, the auxiliary pressure pipe cannot fit the circumferential surface of filter cloths with different diameters. The cutting knife cuts on the left side of the auxiliary pressure pipe, which will cause the filter cloth in the auxiliary pressure pipe to loosen during cutting. Summary of the Utility Model

[0005] In view of this, the utility model provides a cutting device for industrial filter cloth to solve the technical problem that the auxiliary pressure pipe cannot fit the circumferential surface of filter cloths with different diameters, which will cause the filter cloth in the auxiliary pressure pipe to loosen during cutting.

[0006] The utility model is implemented as follows:
