Technical Field
[0001] The utility model belongs to the technical field of backpack strap processing, and specifically refers to a trimming device for processing double-shoulder backpack straps. Background Technique
[0002] The double-shoulder backpack strap is a strap used to evenly distribute the load between the two shoulders. During the processing, it is usually necessary to cut the edge of the fabric to ensure that the edge is neat, thereby improving the overall aesthetics of the strap. The existing trimming devices for processing double-shoulder backpack straps, such as a trimming device for processing schoolbag straps disclosed in the application number CN202320825476.3, when cutting, the pressing plate of the stabilizing component first contacts the strap, and the strap is stably pressed through the supporting spring. And through the setting of the pressing plate, while stabilizing the position of the strap to avoid cutting errors caused by movement, through the pressing of the strap by the pressing plate, when the cutting blade cuts the heated strap, it avoids the situation that the burning and scalding range expands and causes defects in the strap. The cutting is stable and easy to adjust.
[0003] However, in the actual processing process, the trimming device in the above-mentioned prior art trims the strap by lowering the cutting tool, the working steps are cumbersome, and the cutting efficiency is low. Especially when cutting a long strap, continuous feeding of the strap cannot be achieved, resulting in the need to repeat voltage stabilization. Repeated positioning is likely to cause misalignment of the two cutting seams, affecting the aesthetics. Moreover, after the edge is cut, the waste cannot be exported in time, affecting the next work. For this reason, we propose a trimming device for processing double-shoulder backpack straps to solve the above problems. Content of the Utility Model
[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a trimming device for processing double-shoulder backpack straps, which effectively solves the problems of low cutting efficiency and inability to continuously cut the existing trimming devices for processing double-shoulder backpack straps, and solves the problem that repeated voltage stabilization is likely to cause misalignment of the cutting seams when cutting long straps. Especially, it solves the problem that it is inconvenient to clean the cutting waste and affects the next work.
