[0001] The utility model relates to the technical field of paper box processing, in particular to a film laminating device for color paper box production. Background Technique

[0002] In the production process of color paper boxes, the film laminating technology is a crucial link. It can not only enhance the appearance texture of the paper box but also effectively protect the surface of the paper box from abrasion and pollution. However, in actual applications, traditional film laminating devices often have some problems, especially the problem that the protective film and the paper box are not closely attached after film lamination, which directly affects the final quality of the product and its market acceptance.

[0003] In addition, there are also many inconveniences in replacing the used film roll with traditional film laminating devices. It takes a long time to replace, and the replacement process is cumbersome, which not only reduces the production efficiency but also increases the labor intensity of the operators. Moreover, the fixing method of the existing film roll is not reasonably designed, which will cause the film roll to shake during rotation during use, further affecting the film lamination effect.

[0004] In order to solve the above problems, during processing, it can effectively improve the connection between the protective film and the paper box, thereby ensuring that the film lamination is more flat, avoiding the appearance of wrinkles, and facilitating the quick replacement of the used film roll during use, thereby improving the production efficiency of film lamination processing. For this reason, we have proposed a film laminating device for color paper box production. Content of the Utility Model
