[0002] As we all know, laminating and slitting device is a kind of equipment used for laminating and slitting materials. It is usually used to coat a layer of film on the surface of the material to enhance the performance of the material or improve the appearance, and cut the laminating material according to a certain size or requirement to make it a product of specific specifications. This device is widely used in packaging, printing and other industries.

[0003] At present, there are various types of laminating and slitting devices, many of which use a multi-blade (i.e., blade) slitting structure for slitting. This multi-blade slitting structure can usually slitting composite film materials, such as paper, plastic film, metal foil, etc. Slitting is usually required in the following situations: (1) To meet the requirements of different product specifications: when the material needs to be cut into different sizes or shapes. (2) To improve production efficiency: in order to complete the slitting of multiple materials at one time.

[0004] However, in the existing laminating and slitting device technology, some multi-blade head (i.e., blade disc) slitting structures are relatively fixedly mounted on the blade holder during slitting. It is difficult to adjust the spacing between the blade heads according to the actual slitting needs during the slitting process, resulting in greater limitations in use, a smaller scope of application, and difficulty in adapting to the needs of use in different slitting situations. Therefore, the utility model designs a laminating and slitting device to solve the above problems. Utility Model Content
