Description

Technical Field

[0001] The utility model relates to the technical field of film production, in particular to a film annealing and shaping device with a film storage function. Background Art

[0002] Currently, films are increasingly used in our daily lives and production. Films are generally made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, and are used for packaging and as coatings. Plastic packaging and plastic packaging products are occupying an increasingly large market share and have been widely used in the food, pharmaceutical, chemical, and other fields. Food packaging accounts for the largest proportion, such as beverage packaging, frozen food packaging, steamed food packaging, and fast food packaging. These have brought great convenience to people's lives. During the existing film forming process, after a film roll is wound and the reel is replaced and rewound, it is usually cut using a flying knife or a serrated knife. During this time, the film is still in high-speed production, and wrinkles often form inside the reel. For films made of harder materials such as PP, especially thicker films, permanent wrinkles will occur, resulting in the inner 50 or even 200 meters of each roll being unusable after each roll change. This is especially true for self-adhesive co-extruded protective films, which cannot be delivered directly and require rewinding, increasing costs and extending working time. To achieve a wrinkle-free tube bottom, a film storage device is provided.

[0003] At present, almost all existing cast films adopt intermittent winding, which makes the produced film in a relaxed state. It takes 24 hours before it can be slit and rewound for shipment. The reason is that the polyethylene or polypropylene used both have a large shrinkage rate. Direct contact winding will cause shrinkage deformation when the film thickness deviation is unknown, seriously affecting the flatness of the film. As for self-adhesive protective film, because there is stickiness inside the roll, the film in a relaxed state adheres to the back layer in different conditions, which can easily lead to film deformation or lines on the film surface. Therefore, an annealing device is set to solve the problem of film deformation after winding, so that the film can be packaged and shipped after it is unloaded from the machine.

[0004] The film storage device in the existing technology directly drives the film storage roller to move up and down through the cylinder. The cylinder is installed at the top or bottom of the film storage equipment, and installation space needs to be reserved. In addition, the film needs to be annealed during the production process. The traditional method is to use multiple annealing rollers to anneal the surface of the film by external blowing. Air impurities affect the cleanliness of the film.

[0005] Therefore, how to provide a thin film annealing and shaping device with a film storage function to solve the problems existing in the prior art is of great significance to its application. Utility Model Content
