Multilayer film laminating machine

Abstract

The invention discloses a multilayer film laminating machine which comprises a first center unwinding machine, a second center unwinding machine, a third center unwinding machine, a primary laminatingdevice, an embossing device and a dual-station winding device, all of which are arranged on a rack in sequence. Films are output by the first center unwinding machine, the second center unwinding machine and the third center unwinding machine, various layers of films are subjected to primary pressing-laminating forming on the primary laminating device, the composite film is conveyed to the embossing device to be subjected to pattern hot pressing, and the finally-output composite film is wound on the winding device. According to the multilayer film laminating machine, through the primary laminating device, the multiple layers of films are subjected to primary laminating in the laminating device, bubbles are removed effectively, it is guaranteed that no gas exists in an interlayer, the various layers of films are fully laminated firmly, the laminating effect is improved, and the yield is increased.

Description

technical field [0001] The invention relates to a film production technology, in particular to a laminating machine for multi-layer film materials. Background technique [0002] At present, various plastic films have been widely used in various aspects of people's lives, involving fields such as medical and health care, electronic appliances, industry and sports. In the prior art, the film is usually prepared by a laminating device. The coiled material is unwound by an unwinding roll, and then the film is flattened by a traction roll, cooled, and then wound by a winding roll to obtain a finished film. [0003] Films of different materials have different properties. In some special use environments, it is necessary to combine the properties of films of different materials and require double-layer or multi-layer films. Ordinary laminating devices cannot meet actual needs because they can only produce one layer of film. At present, in the production of double-layer or multi-l...

AI Technical Summary

Problems solved by technology

Due to repeated bonding in the prior art, bubbles and unevenness are prone to occur, and the yield rate is reduced, which greatly limits the production and development of this type of film

[0004] In addition, the existing unwinding machine needs to replace the unwinding roll after the unwinding is completed. Due to the large volume and weight of each roll of fabric, it needs to be hoisted by the crane. It takes a long time to replace the fabric roll and restart the machine after a shutdown.

In addition, to replace the cloth roll in the prior art, the bearing seat needs to be disassembled, and the bearing of the rotating shaft machine is pulled out and then installed, which is very inconvenient

[0005] The existing embossing device heats the film material by feeding heat transfer oil through the roller, and then embosses, but the heating method is single, and the heating effect is not satisfactory, which cannot meet the needs of the embossing process of the product

[0006] The winding process of the existing winding device is as follows: the printed or laminated film material is guided by the guide rubber roller, and the film material is continuously wound on the winding roll through the rotation of the winding roller. The distance between some rewinding rollers and guide rollers remains unchanged, while the diameter of the rewinding roller becomes larger and larger as the rewinding progresses, and the tension of the film becomes larger and larger, which may easily cause the film to not be flat Easy to roll, easy to wrinkle
