Nonwoven fabric cutting device

Abstract

The utility model relates to the technical field of non-woven fabrics, and in particular to a non-woven fabric cutting device, comprising a support frame, a support column, a cutting knife and a working cutting table. The upper end of the support frame is fixedly connected to the support column, and the left end of the support column is fixedly connected to a screw rod. In the utility model, a cutting cylinder, a second connecting plate, a sleeve, a compression spring, a pressure plate assembly, a third anti-skid pad and an anti-skid protrusion are arranged, and the cutting cylinder is started. The cutting cylinder drives the pressure plate assembly and the cutting knife to move downward as a whole through the second connecting plate, so that when the cutting knife and the third anti-skid pad contact the non-woven fabric, they continue to move downward. When the cutting knife cuts the non-woven fabric, the pressure plate assembly squeezes the compression spring upward, and the compression spring provides a reverse force to the pressure plate assembly as a whole, so that the pressure plate assembly effectively fixes the two ends of the non-woven fabric through the third anti-skid pad and the anti-skid protrusion, thereby reducing the looseness of the non-woven fabric during cutting, which causes deviation in the cutting position, and improves the cutting accuracy.
