Description

Technical Field

[0001] The utility model relates to an aluminum foil coating machine, in particular to an aluminum foil coating mechanism with a glue leveling roller. Background Art

[0002] At present, the existing aluminum foil coating equipment uses an anilox roller and a glue pressure roller to coat the aluminum foil product. A layer of glue with specific functions is applied on the surface of the substrate and then rolled up after drying.

[0003] When applying glue, because the anilox roller is formed by laser engraving into mesh pits, glue is stored in the mesh pits. The glue in the mesh pits is transferred to the substrate film through the pressure of the anilox roller and the glue pressure roller. The transferred glue has convex spots, which causes uneven coating height, uneven coating surface, uneven thickness, and visually flowery surface, affecting product quality. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the purpose of the utility model is to provide an aluminum foil coating mechanism with a glue-leveling roller, which can perform secondary coating to make the coating more uniform.

[0006] Furthermore, the glue leveling roller is connected to a glue leveling roller arm, and the glue leveling roller arm fixes the unit frame.

[0007] Furthermore, the glue leveling roller is connected to the glue leveling roller arm through a bearing and a shaft with an elastic retaining ring.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: the aluminum foil coating machine of the utility model adds a glue leveling roller, which performs secondary coating on the surface of the aluminum foil coating through the glue leveling roller, further smoothes the coating on the surface of the aluminum foil, makes the coating uniform, eliminates the phenomenon of flowery and uneven coating on the surface of the aluminum foil, improves product quality, and the frequency conversion motor can control the rotation speed of the glue leveling roller to make it consistent with the travel speed of the aluminum foil.
