[0001] The utility model relates to the technical field of paperboard laminating processing equipment, in particular to a laminating device used for paperboard processing. Background Art

[0002] Cardboard is a paper material commonly used in modern life and production. However, due to its characteristics, cardboard is easily affected by moisture or faded during use, causing deformation and damage of the material or affecting its appearance, which in turn affects its use. With the advancement of technology and the discovery of various materials with different properties, people gradually realize that cardboard can be coated with membrane structures of different materials, which can give the cardboard new properties, such as waterproof and scratch-resistant, and can maintain the quality of the cardboard for a long time. Therefore, the cardboard lamination process has been gradually promoted.

[0003] Most of the existing cardboard laminating equipment currently only has basic laminating and extrusion reinforcement functions, but lacks the cardboard dust removal function during the laminating process. Once there is a lot of dust on the cardboard surface, it will seriously affect the laminating effect and reduce the quality of the laminated cardboard. In addition, the single non-adjustable extrusion roller cannot adapt to cardboards of different thicknesses, and the extrusion reinforcement effect is still insufficient.

[0004] In order to solve the above problems, we have made improvements and proposed a laminating device for cardboard processing. Utility Model Content
