Technical Field

Background
The coating is one of the most critical links in the color coating process, and the quality determines the performance and apparent effect reflected by the product. Among the existing color coating industries, the coating modes are various, such as three-roller coating, three-roller back coating, four-roller coating and four-roller back coating, and different coating effects can be achieved by combining different feeding modes and performance requirements of rollers. The roller used in the coating process is generally a chrome-plated iron roller or a rubber roller, or is provided with a scraper mode. The choice of process is also linked to the coating chosen. At present, the paint used in the color coating industry is mainly based on lipid.
As the products required by the existing clients are higher, the requirements on coating construction are very high, and the precoated products of the household appliances have very high requirements on the appearance. At present, precoated products in the family of household appliances still have some problems, especially small shrinkage cavities, which are not only apparent influences, but also potential risks for performance products.
The shrinkage cavities are formed by the materials in the material tray in the coating process, and because the materials are in a state of stirring and blanking for a long time, bubbles are generated due to contact with air in the process, if the bubbles pass through the metering roller smoothly, the bubbles are transferred to the coating roller, the air forms tiny bubbles in the coating, the coating with the tiny bubbles is coated on the substrate to form shrinkage cavities, and the shrinkage cavities are very tiny in the appearance of the product, and can be found under the premise of a magnifying glass in part. However, the shrinkage cavities can cause the problems that the appearance of products is directly affected due to the large grain size of the shrinkage cavities, the shrinkage cavities are through coating holes, namely, the coating has no protection function, and the substrate is directly contacted with the external environment, so that the huge quality risk of rust exists.
For this reason, it is necessary to design a coating mechanism for avoiding shrinkage cavity products.
