Abstract

The utility model relates to a trimming shears, comprising a pedestal, a winding up roller, a reeling up roller a first metal roller, a first rubber roller, an upper roller, a second rubber roller, a second metal roller and a trimming shearing shade; wherein the winding up roller is arranged on the pedestal and is driven by a first electromotor synchronically, and the reeling up roller is driven by a second electromotor synchronically; the first rubber roller, the upper roller, the second rubber roller and the second metal roller are arranged on a bracket between the winding up roller and the reeling up roller from the right side to the left side in turn; and the trimming shearing shade is arranged on the bracket in a shifting way. The trimming shearing shade moves to the position contacted with the up roller after an air cylinder is pressurized pneumatically, so that the trimming shearing shade rotates by following the rotation of the up roller under the driving of an emery cloth belt, so as to realize the trimming shearing. When the trimming shearing process is finished, the first electromotor and the second electromotor drive the winding up roller and the reeling up roller to rotate reversely, thus facilitating the quality inspection of the emery cloth belt. Compared with the prior art, the utility model does not need to assemble and disassemble the emery cloth belt again, thus saving the manual labor and improving the working efficiency.
