[0002] Metal chains are parts used for transmission and transportation. After the metal chains are processed, their surfaces need to be painted to improve the protection of the outer wall of the metal chains and prevent rust.

[0003] In the prior art, the chain is usually closed in a loop, and the chain is fully sprayed with paint through the closed-loop cyclic rotation of the chain.

Most common ones are driven by a driving wheel. When the chain length changes, the size of the driving frame cannot adapt to the length of the chain, and a sprocket gap is set in the chain. Due to the different structures of the chain, it is difficult to ensure that the teeth of the driving wheel are adapted to the gap of the sprocket, which affects the application range of the painting device.

[0037] The upper and lower end surfaces of the chain 11 are fully sprayed with paint by the upper spray head 2 and the lower spray head 7 .

[0038] A pair of left-right symmetrical guide wheels 15 are distributed on both sides of the paint spraying rack 1, and the guide wheels 15 are rotatably installed on the rotating rack 32. An insertion rod 13 is laterally arranged on the outer side of the rotating rack 32. A fixed sleeve 10 is fixedly welded to the front and rear outer walls of the paint spraying rack 1. The end of the insertion rod 13 is slidably inserted in the fixed sleeve 10 through a piston, and a second air valve 31 connected to an external air pump is arranged on the upper end of the fixed sleeve 10.
