Technical Field

[0001] The utility model relates to the field of plastic film production, in particular to a calendering device for plastic films. Background Art

[0002] Before the last century, due to the backward production technology, we could not produce more convenient items for storage and packaging. We mostly used lotus leaves or oiled paper to pack goods, which had a relatively high cost and was inconvenient. It was not until the emergence of plastic films in the last century that brought great convenience to our lives. Plastic films are made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, used for packaging and as a laminating layer. The share of plastic packaging and plastic packaging products in the market is increasing, especially composite plastic flexible packaging, which has been widely used in the fields of food, medicine, chemical industry, etc.

[0003] During the production process of plastic films, a calender is usually used to calender the plastic films and calender them to the required thickness. However, when winding up the plastic films, when cutting the plastic films, it is usually the staff who manually cut the calendered plastic films, which increases the workload of the staff and may cause the cutting edges of the plastic films to be uneven. During the cutting process, the plastic films will be damaged greatly, thus affecting the production quality of the plastic films.

The plurality of rotating rollers 9 can calender the plastic film and guide the plastic film;

[0035] The cutting table 3 for cutting plastic films is located in the middle of the top side of the workbench 1. A groove is provided at the right end of the top side of the cutting table 3. A moving block 5 is arranged in the groove. A lead screw 16 is threadedly connected to the bottom side of the moving block 5. The front and rear ends of the lead screw 16 are rotatably connected to the cutting table 3. By rotating the lead screw 16, the moving block 5 on its outer wall can be driven to move. When the moving block 5 moves, the connecting rod 6 can be driven to move. When the connecting rod 6 moves, the cutting knife 7 can be driven to cut the plastic film after calendering. A first motor 4 is installed at the rear end of the cutting table 3. The first motor 4 can drive the lead screw 16 to rotate. The driving end of the first motor 4 is fixedly connected to the rear end of the lead screw 16. The left end of the top side of the moving block 5 is fixedly connected to a connecting rod 6. The left end of the connecting rod 6 is rotatably connected to a cutting knife 7.

[0036] The number of rotating rollers 9 is three, among which:

[0037] The number on the adjacent sides of the two mounting blocks 2 on the right side is two. Through these two rotating rollers 9, the plastic film can be calendered. And a second motor 8 is arranged at the rear end of the bottom rotating roller 9. The driving end of the second motor 8 is fixedly connected to the rotating roller 9. The second motor 8 can drive the rotating roller 9 at the bottom right end to rotate. The non-driving end of the second motor 8 is fixedly connected to the rear mounting block 2.
