[0034] In use, the paint spraying pump 104 and the high-voltage electrostatic generator 9 are turned on, the paint in the paint cavity 105 is drawn out by the paint spraying pump 104, the paint enters the inside of the annular spray head 7 through the paint drawing pipe 107 and the hose 106, and is sprayed onto the aluminum rod. The paint particles entering the inside of the annular spray head 7 are negatively charged by the high-voltage electrostatic generator 9 and adhere to the aluminum rod. At this time, the aluminum rod is connected to the ground through the positioning L-shaped block 505, the L-shaped connecting block 503, the sliding block 502, and the grounding rod 506 to form a positive electrode. At this time, an electrostatic field is formed between the nozzle and the aluminum rod. Under the action of the electrostatic field, the negatively charged paint particles are attracted to the aluminum rod and are thus adsorbed onto the surface of the aluminum rod. Then the electric telescopic rod 201 is controlled to retract, thereby driving the annular spray head 7 to rise upwards along the aluminum rod, so as to realize spraying on the outside of the aluminum rod.

[0035] When it is necessary to clean the annular spray head 7, the electric telescopic rod 201 is controlled to drive the annular spray head 7 to move to the top of the aluminum rod. Then the two servo motors a202 are controlled to rotate the two threaded rods 203 at the same time, so as to drive the sliding block a2 to move along the threaded rod 203 towards the cleaning cavity 3, thereby moving the annular spray head 7 above the cleaning roller 302 and aligning the center of the annular spray head 7 with the center of the cleaning roller 302. Then the electric telescopic rod 201 is controlled to extend, so as to insert the cleaning roller 302 into the center of the annular spray head 7. The electric motor 301 is turned on to rotate the cleaning roller 302, thereby cleaning the paint remaining on the annular spray head 7 to prevent the paint from solidifying and causing the annular spray head 7 to be blocked.

[0036] The paint spraying pump 104 is connected with the hose 106, one end of the hose 106 extends into the spraying cavity 101, and the annular spray head 7 is connected to the hose 106. The paint drawing pipe 107 is connected to the bottom of the paint spraying pump 104, and the bottom end of the paint drawing pipe 107 extends into the paint cavity 105. In use, the paint in the paint cavity 105 is drawn out by the paint spraying pump 104, so that the paint enters the inside of the annular spray head 7 through the paint drawing pipe 107 and the hose 106 and is sprayed onto the aluminum rod.

[0037] The working principle is as follows:

[0038] In use, the chuck 6 is placed against one side of the positioning L-shaped block 505, and the electric telescopic rod 201 is controlled to extend, driving the fixed block 204 and the annular spray head 7 to move downward, so that the bottom of the annular spray head 7 is in contact with the top of the chuck 6. Then one end of the aluminum bar is inserted into the clamping groove 601 at the top of the chuck 6, and the knob 604 is twisted to drive the screw rod 603 to drive the rubber plate 602 to limit the bottom end of the aluminum bar. Then the paint pump 104 and the high-voltage electrostatic generator 9 are turned on, the paint in the paint cavity 105 is drawn out through the paint pump 104, and the paint enters the inside of the annular spray head 7 through the paint extraction pipe 107 and the hose 106, and is sprayed onto the aluminum bar. The high-voltage electrostatic generator 9 can give the paint particles entering the inside of the annular spray head 7 a negative charge, so that they adhere to the aluminum bar. At this time, the aluminum bar is connected to the ground through the positioning L-shaped block 505, the L-shaped connecting block 503, the sliding block 502 and the grounding rod 506 to form a positive electrode. At this time, an electrostatic field is formed between the nozzle and the aluminum bar. Under the action of the electrostatic field, the negatively charged paint particles are attracted to the aluminum bar and are adsorbed onto the surface of the aluminum bar. Then the electric telescopic rod 201 is controlled to retract, driving the annular spray head 7 to rise along the aluminum bar, thereby realizing the spraying of the outside of the aluminum bar.

[0039] When it is necessary to clean the annular spray head 7, the electric telescopic rod 201 is controlled to drive the annular spray head 7 to move above the aluminum bar, and then the two servo motors a202 are controlled to rotate the two threaded lead screws 203 at the same time, so that the sliding block a2 moves along the threaded lead screw 203 towards the cleaning cavity 3, thereby moving the annular spray head 7 above the cleaning roller 302 and aligning the center of the annular spray head 7 with the center of the cleaning roller 302. Then the electric telescopic rod 201 is controlled to extend, so that the cleaning roller 302 is inserted into the center of the annular spray head 7, and the electric motor 301 is turned on to rotate the cleaning roller 302, thereby cleaning the paint remaining on the annular spray head 7 to prevent the annular spray head 7 from being blocked due to the solidification of the paint.

[0040] Further, after the spraying of the aluminum bar is completed, the servo motor b5 can be controlled to rotate the lead screw 501, driving the sliding block 502 to move along the moving slot 504 towards the transmission mechanism body 8, until the chuck 6 and the aluminum bar are moved to the top of the transmission mechanism body 8, and then are conveyed to the next process by the transmission mechanism body 8 to complete the unloading of the aluminum bar. Then the servo motor b5 is reversed to reset the positioning L-shaped block 505, and a new chuck 6 is placed against one side of the positioning L-shaped block 505, so that the next aluminum bar can be sprayed.
