After using the coating machine for a long time, some malfunctions may occur, and uneven weight distribution of the positive electrode plate is the most common situation, which can lead to the phenomenon of thick middle and thin sides, seriously affecting production progress. The many factors that affect coating uniformity roughly include: material, viscosity of the slurry, uniformity of the slurry, and uniformity of the substrate thickness; In terms of equipment, the smoothness of the radial circle of the scraper and coating roller, the flatness of the axial direction, and the parallelism of the installation of the scraper and coating roller, etc.

The coating roller is an anilox roller, with a diameter of generally Φ 20mm- Φ Between 50mm, it is called micro gravure coating, which is a directional and contact coating method. The rotation direction of the micro coating roller is opposite to the direction of the material film, and the material film is not pressurized by the pressure roller on the coating roller. Traditional gravure coating methods, whether direct or reverse coating, are used. Generally, there are back pressure rubber rollers and mesh rollers with roughly the same diameter as the rubber. Due to the material film being pressed between the rubber roller and the mesh roller, there is a high possibility of defects such as wrinkles and cracks appearing on the coating surface. The contact point between the two rollers during pressing can affect the coating quality due to mechanical, pneumatic, and other factors.
