[0002] In the production and processing of metal products, coating the side of the metal product is a crucial process. Coating not only improves the appearance of the metal product, but also enhances its corrosion resistance, wear resistance and other properties, prolonging the service life of the metal product. However, the current metal product side coating process faces a serious problem. In the actual production environment, there are a large number of dust particles in the air. When the metal product is being coated, these dusts are easily attached to the surface of the side of the metal product;

Secondly, and more importantly, the attached dust will form small gaps or cavities inside the coating. During the drying and curing process of the coating, these gaps or cavities will cause a series of problems, the most common of which is the appearance of bubbles. Bubble bulging not only seriously affects the appearance of the metal product, making the product surface rough and uneven, and reducing the product's grade, but also damages the integrity of the coating, weakens the protective effect of the coating on the metal product, and makes the metal product more susceptible to environmental erosion, shortening its service life.
