[0002] The coating process involves coating a paste polymer, a molten polymer or a polymer melt on a substrate such as paper, cloth, or a plastic film to obtain a composite material or a film, improve the surface function of the substrate, or protect the substrate. Micro-concave coating is a more common coating method, in which a micro-concave roller having a micro-concave texture on the surface is rotated in a silo so that the coating is filled in the micro-concave texture of the micro-concave roller, and the substrate is tangentially contacted with the rotating micro-concave roller, and the substrate moves against the micro-concave roller, so that the coating is transferred to the substrate. In existing patent applications, there are also many coating devices, such as the Chinese invention patent with publication number CN106436460B, which discloses a paper coating device, which uses a sprayer for spraying. In order to ensure uniform spraying, multiple sprayers need to be set along the length direction of the printing roller, resulting in a complex spraying system. Utility Model Content
