Technical Field

[0001] This utility model relates to the field of packaging material processing equipment technology, and in particular to an automatic edge cutting device for processing express delivery bags. Background Technology

[0002] An edge trimming device is a device used to remove excess material from the edges. It is commonly used in the processing of various materials, such as laminating, paper, woven bags, and self-adhesive labels. Edge trimming devices come in a variety of designs and can be customized according to specific application scenarios and needs.

[0003] Currently, most express delivery bags are made of plastic rolls. After being thermoformed, excess material on both sides needs to be removed. Traditional edge-cutting devices have unstable edge quality and are prone to skewing during cutting. At the same time, workers have direct contact with the cutting tools, which poses a high safety hazard. Therefore, we propose an automatic edge-cutting device for express delivery bag processing to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] An automatic edge-cutting device for processing express delivery bags employs a cutting assembly combining a guide rail and an adjustable blade holder. This ensures the disc cutter moves precisely along a preset path, avoiding the skewing problems caused by traditional manual cutting. Simultaneously, the cut flatness is improved by over 90%, meeting the requirements of high-precision express delivery bag processing. Continuous feeding is achieved through the upper and lower rollers of the feeding assembly, with adjustable speed. Waste collection recycles edge material, reducing downtime for cleaning.
