Description

Technical Field

[0001] The invention relates to the technical field of electrochemical aluminum production, and in particular to a coating device for a coating layer capable of improving the weather resistance of electrochemical aluminum. Background Art

[0002] The hot stamping process is a process of hot stamping anodized aluminum onto the surface of an object under a certain temperature and pressure. In order to improve the weather resistance of anodized aluminum, acrylic copolymer resin is usually added to the coloring layer of the hot stamping foil to increase the weather resistance; for example, patent application number CN201810908662.7 discloses an anodized aluminum cold stamping film. This patent mainly improves the weather resistance of anodized aluminum by using acrylic copolymer resin with excellent fullness, gloss, hardness, solvent resistance and weather resistance. The acrylic copolymer resin does not change color or turn yellow when baked at high temperature, and the thermoplastic acrylic resin does not undergo further cross-linking during the film forming process;

[0003] In the production process of hot stamping foil, the hot stamping foil on the substrate layer needs to be transferred to the surface of the plastic label. This step is mainly completed by a laminating machine;

[0004] For example, patent application number CN202011149377.5 discloses a hot laminating machine and its hot stamping process. The operator of the patent rolls the plastic label to be hot stamped onto the unwinding roller, then loads the hot stamping film onto the unwinding roller, and then sticks the plastic label and the hot stamping film tightly together, and passes them through the compacting roller and the hot pressing roller together. The distance between the hot pressing roller and the compacting roller is adjusted by the adjusting device, and then the pressure between the hot pressing roller and the compacting roller is adjusted, so that the pattern on the hot stamping film can be compacted and pasted onto the plastic label, and then the pattern on the hot stamping film is hot stamped onto the plastic label by heating the hot pressing roller, so as to realize a continuous and uninterrupted cyclic hot stamping process. At the same time, due to the rotation of the hot pressing roller, the plastic label and the hot stamping film are evenly heated, so that the plastic label and the hot stamping film are evenly heated, thereby improving the flatness of the surface of the plastic label after hot stamping, which has the effect of improving the quality of the plastic label after hot stamping.

[0005] However, during the lamination process, this patent lacks preheating of the hot stamping foil. At the same time, once the hot pressing roller, compaction roller, and adjustment device in this patent fail, it is difficult to repair them. At the same time, the unwinding roller, film unwinding roller, film winding roller, and winding roller are all unidirectionally positioned, and their stability is poor after long-term rotation. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a laminating device for the laminating layer which can improve the weather resistance of electrochemical aluminum, so as to solve the problems of inconvenient maintenance, lack of preheating and poor stability of the laminating device of the hot stamping foil in the prior art described in the background technology.
