[0002] Plastic packaging and plastic packaging products are taking up an increasingly larger share of the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion.

[0003] Since plastic film is a consumable, two film reels are usually arranged in the film splicing device on the packaging machine. When the plastic film on one of the film reels is used up, the plastic film on the other film reel is butted together by "film splicing" to achieve the replacement of the plastic film. However, the butt joint of the plastic film is often thicker, resulting in an overly thick edge seam at the butt edge and burrs on the edge of the film, which affects the appearance of the plastic film. The existing solution is to scrape the butt joint of the plastic film with a scraper to remove the burrs. However, the scraper is generally fixedly installed and cannot be disassembled, making it difficult to replace the scraper. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a plastic film automatic replacement structure, which solves the problem that the scraper on the existing plastic film automatic replacement structure is generally fixedly installed and cannot be disassembled, resulting in difficulty in replacing the scraper.
