Spray device, system and method of using it on spray container pallet part

Abstract

A spray finishing device includes at least one spray gun, a fixing frame used for fixing the spray gun, a swing mechanism fixed with the fixing frame and used for adjusting the angle of the spray gun frame; and a differential device which respectively drives the swing mechanism and the fixing frame through a first chain and a second chain with different speeds. The swing mechanism includes a swing block fixed at the bottom part of the fixing frame, a swing shaft, one end part of which passes through the swing block and is fixed with the swing block; and a swing arm fixed with the other end of the swing shaft. In order to optimizing the structure, the spray finishing device also includes a moving block provided with a through hole and fixed with the swing block; among which, the swing shaft passes through the through hole. The first chain and the second chain can be respectively coupled to the bottom parts of the swing block and the moving block, thus allowing the spray finishing device of the invention to automatically adjust the swing angle of the spray gun; thereby being capable of design the swing angle and the swing direction according to detail application.

Description

technical field [0001] The invention relates to a spraying equipment, in particular to an automatic spraying system used for container spraying and a method for spraying the inside or outside of a panel. Background technique [0002] For containers that have been widely used, the external spraying process has already achieved mechanized automatic spraying. Due to various reasons, the sprayers in the box are still in the manual process stage. Although various attempts have been made for realizing the automatic spraying in the case, so far, no ideal scheme can be seen. [0003] For the paint spraying outside the box, generally use the existing automatic paint spraying machine 200a, such as Figure 1A As shown, the automatic painting machine 20 is arranged outside the box of the container 10, and can move along the longitudinal direction B of the container (ie, the horizontal direction). The roof spraying device 21 of the automatic paint spraying machine 20 is fixed on the to...

Problems solved by technology

The disadvantage of spraying with this method is that the coverage between paint and paint is extremely uneven, and the difference in film thickness is too large, resulting in more paint loss

[0004] On the other hand, the paint sprayed by the spray gun of the existing automatic paint spraying machine is a flat fan, and its effect is the same as that of the paint brush. ,like Figure 1B Shown is a schematic view of one end of the container 10, wherein the corners 14 and 15 of the bottom formed after the bottom plate 13 is connected with the two side plates 12, and the top corners 16 and 15 formed after the side plate 12 is connected with the top plate 11 17. Both the inner and outer sides of these corners become the dead zone of spraying operation, because the spraying operation surface of this prior art is only a flat fan surface

In addition, the automatic paint spraying machine of the above-mentioned prior art is complex in structure, expensive in use, frequent in use, and high in maintenance cost
