Description

Technical Field

[0001] The invention relates to the technical field of packaging processing, in particular to a medical device packaging bag processing and cutting device. Background Art

[0002] Blister is a transparent plastic with a specific convex shape made from a transparent plastic sheet using the blister process. It is covered on the surface of the product to protect and beautify the product. It is also called blister or vacuum cover. In the field of aseptic packaging of medical devices, blister (also called blister cover, blister, etc.) is a common packaging form. This packaging is usually made of hard plastic and formed into a specific convex shape through hot / cold processing. Then the blister is filled with medicines or other items and sealed with covering materials such as aluminum foil. The main function of the blister is to protect the surface of the product while beautifying and protecting the product.

[0003] At present, when blister packaging is performed on surgical medical devices and injection tools, it is necessary to cut the rolled blister sheets, cut the blister sheets into shapes, and then adsorb them into a blister machine for molding. Existing blister sheet cutting is performed by punching cutting, so that the cut of the blister sheet is smooth, but punching cutting may produce sheet debris. At this time, the workshop operator will hold a high-pressure air gun to clean the processing table and use the high-pressure air gun to clean the generated debris. However, when the high-pressure air gun is used to blow and clean, the position of the sheet will be shifted, which increases the subsequent labor. In addition, a low cleaning frequency leads to a decrease in the quality of sheet cutting, and a high cleaning frequency increases the labor intensity of the operator. Summary of the invention
