Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to a coating machine that can achieve uniform coating. Background Technology

[0002] A coating machine is a mechanical device used to uniformly coat liquid or semi-liquid substances such as paints, inks, adhesives, and slurries onto the surface of various substrates. It is widely used in many industries, such as printing, packaging, electronics, photovoltaics, automotive manufacturing, and construction. The basic function of a coating machine is to apply paint to the surface of a substrate, ensuring the uniformity, quality, and thickness of the coating to meet the product's usage requirements. Classification by coating method: Blade coating machine: Uses a blade to uniformly coat the paint; typically suitable for thicker coatings. Roller coating machine: Uses multiple rollers to uniformly coat the substrate surface; suitable for thin coatings and large-area coatings. Spray coating machine: Uses high pressure to atomize paint into small droplets and spray them onto the substrate surface; suitable for substrates with complex or irregular shapes. Dip coating machine: Dips the substrate directly into a paint tank; the coating process is simple and suitable for mass production. Blade-roller coating machine: Combines the functions of a blade and a roller, enabling control of the coating thickness; suitable for applications requiring high coating precision.

[0003] In existing technologies, some coating machines require manual addition of the coating material to be applied by inspectors directly above the coating roller during operation. Due to the limited material capacity above the coating roller, some areas consume coating material faster than others. If the material is not added in time, a material vacuum period can easily occur in that area, resulting in the substrate surface corresponding to that area not being coated with the required material, thus causing uneven coating on the substrate surface.
