Description

Technical Field

[0001] The utility model belongs to the technical field of film folding processing equipment, and particularly relates to a folding film edge pressing device. Background Art

[0002] As we all know, folded film is a kind of roll film that is folded and closed on one side and opened on the other side and rolled up in a certain rolling direction. It is mainly used for packaging. Folded film has the advantages of transparency and easy operation. It is mostly used in books, electronics, circuit boards, hospitals and other units.

[0003] Since the folded film is a roll film that is folded and closed on one side and opened on the other side and rolled up in a certain rolling direction, the thickness of the two sides will be unbalanced because one side is folded and the other side is open. Therefore, edge accumulation is likely to form on one side of the folded film during the folding process, and a pressing device will be used in the rolling process of the folded film. The pressing device of the folded film mainly has the function of pressing the two ends of the film material during the rolling process, so that the folded position of the film material will not deviate during the rolling process. The flatter the folded side of the film material is compacted, the easier it is to roll the film neatly. The working principle of most pressing equipment is to adjust the pressing edges on both sides to a suitable height, place the two side ends of the film material under the two pressing plates, and then lift the pressing plates downward. The pressing plates press the film material without affecting the movement of the film material, thereby achieving the pressing effect.

[0004] At present, most of the edge pressing devices for making folded films on the market include structures such as a workbench, a lifting mechanism, and a pressing plate. Although the two sides of the film material can be pressed well, the device is not convenient for adjusting the distance between the two pressing plates, and thus is not convenient for pressing folded films of different widths, which greatly reduces the wide range of use of the device and thus narrows the scope of application of the device. In addition, the existing edge pressing device for folded films still adjusts the lifting and lowering of the pressing plate by manually rotating the screw rod. This process is relatively slow and the clamping force is small, which seriously affects the edge pressing effect. Utility Model Content
