Description

Technical Field

[0001] This utility model relates to the field of plastic film processing technology, and in particular to a plastic film flattening device. Background Technology

[0002] Films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins are used for packaging and as coating layers. Plastic packaging and plastic packaging products are gaining an increasingly larger market share, especially composite plastic flexible packaging, which is widely used in the food, pharmaceutical, and chemical industries. Food packaging accounts for the largest proportion, including beverage packaging, frozen food packaging, retortable food packaging, and fast food packaging. These products have brought great convenience to people's lives.

[0003] Plastic film flattening devices are mainly used to flatten plastic films during production or processing, removing wrinkles, bubbles, and irregular shapes from the film surface to ensure a smooth and uniform surface. Films treated in this way are better suited for subsequent processing, such as printing and packaging, ensuring production quality. The main functions of plastic film flattening devices are: Removing wrinkles and ripples: Through the pressing action of rollers, wrinkles and ripples on the film surface can be eliminated, ensuring the film's flatness. Uniform surface: The flattening device ensures a smooth and uniform film surface, suitable for subsequent processing operations such as printing, coating, and packaging.

[0004] Improved processing precision: A smooth film improves the processing precision in subsequent production stages, ensuring the film is less prone to tearing and deformation during processing. Enhanced visual appeal: A smoother film surface enhances its appearance, especially important for transparent films where surface smoothness significantly impacts visual quality.

[0005] In the present technology, plastic films are prone to wrinkling after production, resulting in unevenness and air bubbles after winding, which is not convenient for subsequent use. Therefore, we propose a plastic film flattening device to solve the above-mentioned problems. Utility Model Content

At this time, adjust the height of the pressure roller 5 according to the usage requirements, and first push the pressure rod 6 to rotate. At this time, the rotation of the pressure rod 6 will drive the connecting shaft 7 to move, thereby pushing the connecting groove, so that the moving frame 8 moves forward. The forward movement of the moving frame 8 will drive the moving plate 9 to move forward. The guide frame 12 can conveniently limit the moving plate 9, so that the moving plate 9 moves back stably. When the moving plate 9 moves, it will compress the spring 11 and drive the positioning plate 13 to move back. At this time, the moving positioning plate 13 will disengage from the positioning groove, thus fixing the rod. 3. Unlock. At this time, a positioning groove is opened at the corresponding position of the fixing rod 3 according to the height of the plastic film. By pushing the fixing rod 3 down, the pressure roller 5 will move down. When it moves to the appropriate height, push the pressure rod 6 to rotate and reset. The rotation of the pressure rod 6 will drive the connecting shaft 7 to move. The movement of the connecting shaft 7 will drive the moving frame 8 to reset. At the same time, the spring 11 loses its restraint and pushes the moving plate 9 to move backward and reset. The moving plate 9 will drive the positioning plate 13 to move and engage with the positioning groove to fix the fixing rod 3, so that the pressure roller 5 is fixed at the current height. By pushing the plastic film on the base plate 1 to move laterally, the pressure roller 5 can be used to flatten the plastic film.
