Description

Technical Field

[0001] The utility model relates to the technical field of processing devices, in particular to a plastic bag processing and hot cutting device. Background Art

[0002] Plastic bags, made from plastic (common materials include polypropylene, polyester, and nylon), play an indispensable role in our daily lives. They are not only widely used to carry a variety of items, but are also popular for their low price, light weight, spacious capacity, and convenient storage. In the plastic bag production process, thermal cutting machines are key equipment for precise cutting, ensuring that each bag is cleanly cut to the desired size and shape.

[0003] Because plastic bags are typically thin, the high temperatures generated during thermal cutting can melt the plastic at the cut and easily adhere to the cutter. This adhesion not only makes it difficult to cleanly separate the cut plastic bag, but also seriously affects the quality of subsequent cutting operations. The plastic residue adhering to the cutter must be promptly removed. Furthermore, the plastic bag must be secured during the cutting process to prevent displacement. Especially with the diverse sizes and widths of plastic bags today, securing these bags has become a pressing issue. Therefore, a plastic bag processing and thermal cutting device is needed to address this issue. Utility Model Content
