During the rotation of the bolt body 6, the nozzle 12 sprays paint on it.

[0039] During the painting process, the negative pressure fan 102 is started by the controller, and the negative pressure fan 102 generates negative pressure. The harmful gas emitted by the paint inside the frame 3 is collected through the air inlet pipe 105 and transmitted to the inside of the purification box 104. The odor is adsorbed when passing through the activated carbon adsorption net 103, so that the device can effectively purify the paint odor, protecting the environment while protecting the health of the workers. When the device is finished working, the pull plate is pulled outward, and the pull plate drives the activated carbon adsorption net 103 to move outward. The movement of the activated carbon adsorption net 103 drives the plug block 1031 to move, so that the plug block 1031 is separated from the slot 1041, until the activated carbon adsorption net 103 is taken out from the inside of the purification box 104 and replaced, thereby improving the purification effect of the device.
