Description

Technical Field

[0001] The utility model relates to the technical field of flattening mechanisms, in particular to a casting online film belt flattening mechanism. Background Art

[0002] The production methods of plastic film generally include film blowing, extrusion, cast film, etc. The film produced by cast film technology is too thin to wrinkle when it is rolled up, and cannot be rolled up directly.

[0003] At present, a tension-controlled flattening device for casting equipment is disclosed in a Chinese patent announcement with the announcement number CN217867272U, which includes a frame and a roller rotatably connected to the frame, wherein the frame is slidably connected to two telescopic movable rods in the vertical direction, and the two movable rods are respectively located at the two ends of the roller, and the movable rod is rotatably connected to one end of the movable rod close to the roller to cooperate with the roller to press the side of the film, and the frame is provided with a driving assembly for driving the movable rod to slide at both ends of the roller. Under the pressing action of the movable pulley and the roller, the present application makes it difficult for the two sides of the film to deviate, thereby achieving the flattening effect of the film during the traction process.

[0004] In actual use, it is found that when wrinkles have already occurred in the film during transmission or wrinkles have occurred at the edge of the film, the pulleys and rollers are unable to flatten the wrinkles that have already occurred or the wrinkles at the edge due to the limited traction and compression range. Therefore, we proposed a cast-film online film belt flattening mechanism to solve the above problems. Utility Model Content
