Description

Technical Field

[0001] The invention relates to the technical field of color coating machine cleaning, and in particular to automatic cleaning equipment and a cleaning process for a coating machine used in a color coating continuous unit. Background Art

[0002] Coating performance is one of the most important characteristics of color-coated steel sheets. It is not only related to the production process of color-coated steel sheets, but also closely related to the quality of the coating itself. Therefore, the cleanliness of the coating on the roller and in the paint tray is a key factor affecting the quality of color-coated steel strip coating.

[0003] At present, the color coating unit is cleaned manually or with the cooperation of manual cleaning. Since color coating coatings are mostly toxic materials, which are harmful to the environment and human body, the color coating machine is set in the paint room. In addition, different types and / or colors of paint need to be applied according to different color coating requirements during the color coating production process, and personnel need to enter the paint room to work. When changing the type and / or color of paint, it is necessary to use paint cleaning agent to clean the belt roller, coating roller, paint tray and other areas, and then add new paint to the paint tray. Since the cleaning agent is a harmful substance that is more harmful to the human body, and the cleaning work time is long and the work content is multi-tasking, the painting cleaning is a high-risk process. At present, manual cleaning before changing the paint requires wearing protective equipment according to the operating instructions before entering the paint room to work.
