Description

Technical Field

[0001] The utility model belongs to the technical field of re-pressing devices, and in particular relates to a re-pressing device for a composite film. Background Art

[0002] At present, most of the existing composite films are rolled and laminated. However, during the use of most rolling devices, the raw material on the raw material roller will become less and less, causing the tension of the laminating roller on the raw material to become looser and looser, resulting in wrinkles on the raw material, resulting in unqualified products and a waste of resources.

[0003] The patent with application number 202220620061.8 discloses a laminating device for a triple-proof fabric composite film, including a laminating box, one end of the laminating box is provided with two raw material rollers from top to bottom, one side of the laminating box is provided with two feed ports from top to bottom, and two tensioning mechanisms for preventing wrinkles from appearing in the raw materials are provided in the laminating box from top to bottom, both sides of the laminating box are provided with slide grooves for facilitating the movement of the tensioning mechanism, one side of the laminating box is provided with a laminating mechanism for laminating the raw materials, one end of the laminating box is provided with a discharge port, and support feet are provided around the bottom of the laminating box.

[0004] The above technical solution adjusts the tension of the composite film by adjusting the position of the tensioning mechanism. Since the above technical solution lacks positioning of the raw material roller, the tension increases during the adjustment process, resulting in an increase in the conveying speed of the raw material roller. In addition, the two raw material rollers are affected by their own friction and cannot ensure completely synchronous rotation, making it impossible for the two raw material rollers to maintain exactly the same conveying speed, affecting the relaxation of the raw material during the pressing process.
