Steel plates are divided into thin steel plates <4 mm (the thinnest is 0.2 mm), medium and thick steel plates 4~60 mm, and extra thick steel plates 60~115 mm according to thickness. Steel plates are divided into hot rolling and cold rolling according to rolling. The width of thin plates is 500~1500 mm; the width of thick plates is 600~3000 mm. Thin plates are divided into ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron thin plates according to steel types; according to professional uses, there are plates for oil drums, enamel plates, bulletproof plates, etc.; according to surface coatings, there are galvanized thin plates, tin-plated thin plates, lead-plated thin plates, plastic composite steel plates, etc. After searching, a device for spraying paint on the surface of a machined steel plate was disclosed with the publication number CN110976145A; There are still certain problems in the use of the above-mentioned preparation equipment. For example, in the process of processing the steel plate, although the surface of the steel plate has been ground and polished, there are still certain defects on its surface. Sometimes even some debris will adhere to the surface, affecting the spraying effect of the steel plate. After spraying it, a drying and heating structure is often set inside the spraying equipment, such as a heating wire, to dry and heat the paint just sprayed on the surface of the steel plate. After long-term use, the heating wire is easily damaged and it is very inconvenient to replace. Summary of the invention
