Description

Technical Field

[0002] Plastic bags are bags made of plastic (commonly used plastics include polypropylene, polyester, nylon, etc.) as the main raw material. They are indispensable items in people's daily lives and are often used to hold other items. They are widely used because of their low price, extremely light weight, large capacity and easy storage.

[0003] When in use, the existing plastic bag hot cutting devices mostly manually lay the plastic bags flat on the top of the cutting table and then directly perform hot cutting. If the plastic bags are blown by wind during hot cutting, the plastic bags may be offset, resulting in an error in the hot cutting position, affecting the quality of the finished product. At the same time, after the hot cutting is completed, the plastic bags may adhere to the upper end of the hot cutting knife, affecting the subsequent cutting. The practicability is low and it brings certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a hot cutting device for plastic bag production. Utility Model Content
