[0002] Powder spraying equipment is a relatively commonly used one in aluminum profile surface treatment equipment. It is a device that sprays powder onto workpieces with a spray gun, so that the powder adheres to the surface of the workpieces to achieve functions such as anti-corrosion.

[0003] In the prior art, a Chinese patent with the publication number of CN215655893U discloses a horizontal aluminum profile powder spraying equipment, which adopts the scheme of "including a Z-direction linear module, a spray gun assembly, an aluminum profile hanging rack, and a hanging auxiliary assembly. The technical key points are: the hanging auxiliary assembly includes two connecting hooks, a U-shaped connecting piece for hooking the end of the aluminum profile, and a counterweight assembly for hooking the lowest aluminum profile. One end of the U-shaped connecting piece is inserted into the end of the upper aluminum profile, and the other end is inserted into the end of the lower aluminum profile; the spray gun assembly includes a fixed frame, a plurality of spray guns, a lower connecting rod group and an upper hinged ear group arranged at the rear of the fixed frame, and a telescopic cylinder hinged to the upper hinged ears corresponding to the upper hinged ears one by one. The lower connecting rod is hinged to the lower connecting ear on the slider of the Z-direction linear module, and the cylinder body of the telescopic cylinder is hinged to the upper connecting ear on the slider of the Z-direction linear module".
