Description

Technical Field

[0001] The utility model relates to the technical field of metal plate processing equipment, in particular to a surface coating equipment for metal plates. Background Art

[0002] Metal sheets are important basic materials for modern urban construction and production and life. They are widely used in construction, hardware and other fields. Metal sheets usually refer to regular rectangular materials of different sizes and thicknesses produced by metal or alloy materials after cutting and other processes. The properties of different metal alloy sheets are also different. With modern technology, metal sheets can be coated to add new properties that the metal sheets did not originally have. The principle of coating is mainly to change its optical, physical or chemical properties by forming a thin film on the surface of the material. The coating methods include thermal evaporation coating, sputtering coating, electroplating and chemical vapor deposition. Among them, large plates are usually coated with evaporation vacuum coating machines.

[0003] Most of the existing coating equipment cannot coat multiple large plates at a time. Although the evaporative vacuum coating machine can coat multiple large plates at a time, the lifting of the top cover is usually done by hoisting. The continuous shaking during the lifting process is very unstable and poses certain safety hazards. In addition, the plates often need to be tied and fixed with tools, and there is no support at the bottom. There is a risk of the plates falling off and falling into the coating tank, which may lead to safety accidents or loss of the plates.

[0004] In order to solve the above problems, we have made improvements and proposed a surface coating equipment for metal sheets. Utility Model Content
