Description

TECHNICAL FIELD

[0001] The utility model relates to the field of film production technology, especially to a film production edge turning and flattening device. BACKGROUND

[0002] During the production and winding of the film, as the winding diameter increases, the pulling force increases, which causes the film edges to turn up. Therefore, the film edges need to be flattened during the film processing.

[0003] For example, a patent with the application number 202420345928.2 discloses a film edge turning and flattening device. The device includes a base, two clamps symmetrically installed on the top side of the base, a rotating shaft installed between the two clamps, a winding roller on the rotating shaft, a sliding slot on the side of the two clamps above the winding roller, and a sliding rod installed between the two sliding slots. When the film is wound, the device adjusts the speed of the winding roller through the driving element and the connecting rod, ensuring that the speed of the film being wound remains unchanged. When the film edges are flattened, the device prevents uneven heating of the film caused by the increase in winding speed, which may lead to incomplete flattening of the film and affect the quality of the film.

[0004] According to the description in paragraph

[0026] , when the film is processed and wound, the film edges are flattened by the flattening piece 12, and then the rotating shaft 3 is driven to rotate by the driving element 11, which in turn drives the winding roller 4 to rotate, thereby winding the processed film.

[0005] As shown in the above content and the accompanying drawings, the flattening piece of the device is fixed in position, and it can only flatten the film once, which is not very effective. Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. UTILITY MODEL CONTENT

[0010] The driving assembly comprises a driving motor fixedly connected with the rack, a cam fixedly installed at an end of a driving shaft of the driving motor, and a connecting rod hingedly connected with the cam at one end, and the other end of the connecting rod is hingedly connected with the mounting plate.

[0011] Further, a guide slide rail is mounted on the surface of the rack, and the bottom of the mounting plate is slidingly connected with the guide slide rail.
