Problems solved by technology
A large amount of volatile solvents are used in the gravure printing process, and the solvent is released during the drying process, which has caused great harm to the environment and the health of the staff
The digital printing process is to directly light-cure after printing the UV ink on the surface of the sample, which greatly improves the environmental protection. However, the current production basically adopts the single-board production method, which is relatively low in efficiency, and the research and development costs of coil production are high, and most enterprises cannot invest in it.

Abstract
The invention provides production equipment and a production method for environment-friendly printing of a color-coated sheet. The production equipment comprises a watermark film unwinding mechanism, a spraying mechanism, a film covering mechanism, a drying mechanism, a UV roller coating mechanism, a light curing mechanism and a conveying chain used for conveying the color-coated sheet, wherein the watermark film unwinding mechanism is arranged above the conveying chain, the spraying mechanism is arranged above the watermark film unwinding mechanism, and the film covering mechanism and the conveying chain are located on the same horizontal line. During printing of the color-coated sheet, the spraying mechanism uniformly sprays cold water on the surface of a watermark film with an ink layer, the film covering mechanism transfers the ink layer to the surface of the color-coated sheet, the drying mechanism performs baking treatment on the color-coated sheet, the UV roller coating mechanism coats the surface of the color-coated sheet with a UV coating, and the light curing mechanism performs light curing treatment on the color-coated sheet. According to the production equipment and the production method, the color-coated sheet is produced in a rolling manner, a cold water pasting technology is adopted in the printing and color-coating process, the diversity of appearance patterns can be achieved, and the environmental requirement of production can be thoroughly met.
Description
technical field [0001] The application relates to the technical field of color-coated board printing, in particular to a production equipment and production method for environmentally friendly printed color-coated boards. Background technique [0002] Traditional PCM color-coated board, as one of the existing boards, is widely used in the fields of construction, home furnishing and home appliances. It is mainly used in the decoration of household electrical equipment shells, such as refrigerator door side panels, water heater shells, TV back panels, washing machine panels, etc. . [0003] At present, color-coated boards are generally printed, so that various characters and patterns are attached to the surface of the color-coated boards, so as to increase the aesthetics of the appearance of home appliances. [0004] There are two main printing processes in the domestic color-coated board industry, one is gravure ink printing, and the other is digital printing. A large amoun...
