Description

Cloth burr trimming mechanism Technical Field The utility model relates to the technical field of cloth processing apparatuses, in particular to a cloth burr trimming mechanism. Background In the textile manufacturing and finished fabric processing processes, the problems of exposed thread ends and accumulated burrs are easy to occur at the edges of the fabric in the cutting, sewing or transporting processes, so that the appearance quality of the finished fabric is affected, the problems of thread off, breakage and the like are possibly caused in the subsequent use, and the product grade is reduced or reworking treatment is caused in severe cases. Therefore, efficient trimming of the edge thread ends and burrs of the cloth becomes an indispensable procedure in the textile industry. At present, the cloth burr trimming tools commonly used in the industry mainly comprise the following types: the manual scissor type pruning tool is simple to operate and convenient to manually prune, but has low shearing efficiency, high shearing quality, high dependence on manual experience and poor consistency and low efficiency.
