Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of roll coating machines, and specifically relates to a UV roll coating machine. BACKGROUND

[0002] The UV roll coating machine is a device for coating processing, which cures paint by using an ultraviolet (UV) lamp, uniformly applies liquid paint on the surface of a substrate by roll coating, and then rapidly cures the coating by a UV light source. The roll coating process ensures the uniformity and smoothness of the coating thickness. The main advantages of the UV roll coating machine include rapid curing, environmental protection (no solvent required), high efficiency, energy saving, high coating hardness, good wear resistance, etc. It is widely used in the furniture manufacturing, building materials, printing, electronic products and other industries.

[0003] A UV roll coating machine is disclosed in the utility model patent with the publication number CN217342068U, which relates to the technical field of roll coating machines. The utility model comprises a bottom plate, a roll coating machine body is arranged on the top of the bottom plate, a drive motor is arranged on the side of the roll coating machine body, a roller is arranged on the output end of the drive motor, the roller extends into the roll coating machine body and is rotationally connected with the roll coating machine body. The utility model can drive the brush to move horizontally and circularly on the surface of the roller by the cooperation of the stepping motor, the first tooth, the second tooth, the connecting plate, the brush, the annular sleeve and the air cylinder. The brush can remove the paint attached to the surface of the roller, avoiding manual cleaning of the paint and improving the cleaning efficiency of the roller.

[0004] However, in actual use, it is found that the device removes the paint attached to the surface of the roller by moving the brush to improve the cleaning degree of the roller.

Even when the glue has not solidified, the brush will be contaminated with a large amount of paint during the cleaning process, which will affect the subsequent cleaning effect. Therefore, a UV roll coating machine is provided. UTILITARIAN CONTENT
