Description

Technical Field

[0001] The utility model relates to the technical field of entrance doors, in particular to a door leaf side spray painting processing operation line. Background Art

[0002] With the gradual improvement of living standards, the appearance of various products has become a key point that cannot be ignored. The existing door panels need to be painted before processing, which can not only improve the aesthetic performance, but also protect the internal structure of the door panels and extend the service life of the door panels. The current painting process is mostly to manually spray the paint on the door panels through a spray gun, and then place them in a heating furnace for drying. This method not only has high labor and transportation costs, but also has poor uniformity in manual spraying, which seriously affects the appearance of the door panels. At the same time, after spraying the paint, it is necessary to wait for the paint to dry, which takes a long time to make, with low work efficiency and is not easy to spray paint evenly. When thicker door panels are processed in the painting process, not only the front and back sides need to be painted, but also the sides need to be painted. Traditional painting processes often require multiple flipping, loading and unloading, clamping, etc. to achieve side processing. Traditional side painting processes for door panels not only have the problems of low efficiency and long construction period, but also the problems of lack of flatness and fullness on the side of the door panels.
