Description

Technical Field

[0001] The invention belongs to the technical field of injection molding equipment, and in particular relates to a surface treatment device for preparing a high-gloss injection molding panel. Background Art

[0002] In the preparation process, the injection-molded panel is firstly injection-molded by the injection molding machine, and then enters the next surface treatment process. The surface treatment of the injection-molded panel mainly adopts the use of spraying equipment to spray the surface of the injection-molded panel so that the injection-molded panel can reach the desired color. At present, the spraying method of injection-molded panels in the production workshop is mainly sprayed by manual hand-held spray guns. The size of injection-molded panels is small and the output is large. If it is simply relied on manual spraying, the production efficiency of the workshop will be greatly affected and it will not meet the needs of automated assembly line production. The general assembly line spraying device cannot spray the injection-molded panel on both sides. The injection-molded panel needs to be turned over and sprayed again to spray the surface of the injection-molded panel evenly. Summary of the invention
