Description

Technical Field

[0001] The utility model relates to the technical field of coating and leveling, in particular to a leveling device for coating liquid media. Background Art

[0002] Sweeping rollers are equipment components used on specific production lines. They are mainly used to smooth materials or slabs, especially in artificial board production lines, metal sheet processing, and plastic film production. Their main function is to eliminate the unevenness of the material or slab surface through rotation and smoothing action, thereby improving the quality and appearance of the product.

[0003] The existing sweeping roller will reverse and destroy the material that was originally swept when it is not powered. Therefore, when the sweeping roller is not powered or the material breaks during the sweeping process, the position of the sweeping roller needs to be locked. In addition, the distance between the sweeping roller and the adjacent roller is different, and the contact area between the sweeping roller and the material is also different. It is necessary to adjust the distance between the rollers under different materials to increase the friction between the material and the sweeping roller to avoid idling when the sweeping roller contacts the material. The liquid medium cannot be coated on the material. The existing liquid medium coating is sprayed on the surface of the material, and the flatness of the coated liquid cannot be guaranteed.
