Description

Technical Field

[0001] The utility model relates to the technical field of film laminating devices, in particular to a laser film laminating device. Background Art

[0002] Laser film is a technology that uses a laser printer to output digital images directly onto film. A laser printer can print images directly onto film through a laser beam, thereby achieving high-quality graphic printing. Laser film is widely used in the printing industry, and its lamination treatment is an important means to improve film quality and protect the film. Specifically, the lamination treatment has the advantages of protecting the film surface, improving film operability, and enhancing film durability. When laminating laser film, it is usually performed on a corresponding laminating device. There are many types of laminating devices on the market, and most of them use suction cups to adsorb the film body and then stick it to the film for lamination.

[0003] However, when using a suction cup for adsorption, the adsorption process of the suction cup easily causes the film to be not smooth enough, resulting in wrinkles on the surface of the film. In addition, the use of a suction cup for adsorption also requires the use of a corresponding transmission part that moves up and down. The up and down movement process will relatively delay time, affect the laminating efficiency, and bring inconvenience to the user. In view of this, we propose a laminating device for laser film.
