The drive tube 31 is connected to the airway in the fixed column 2, and the airway in the fixed column 2 is connected to the air pump through a pipeline. The fixed column 2 is provided with a fixed ring 32 connected to the airway therein, and a number of bottom tubes 33 connected to the fixed ring 32 are evenly distributed along the fixed ring 32. The bottom tube 33 is obliquely arranged on the fixed ring 32, and a telescopic tube 34 is slidably inserted on each bottom tube 33. The telescopic tube 34 is evenly distributed on the side of the fixed column 2 with a number of air outlet holes 341, a retaining ring 342 is provided on the outer side of the lower end of the telescopic tube 34, and a funnel-shaped derivation tube 343 is provided on the inner side of the telescopic tube 34.

[0024] In addition, the spraying mechanism 4 includes a cylinder 1 41, a nozzle 47, an adjustment component 46 and a motor 48. The cylinder 1 41 is installed on the top of the box body 1 and a lifting frame 42 is provided at the lower end of its piston rod. The lifting frame 42 is provided with a guide rod 43 slidably connected to the box body 1. A gear 1 44 is rotatably connected in the lifting frame 42.

The adjustment component 46 includes a cylinder 2 462 and an adjustment plate 461. One end of the adjustment plate 461 is hinged to the fixed plate 45 through a pin shaft, and the other end of the adjustment plate 461 is connected to the bracket 463 on the nozzle 47. The cylinder body of the cylinder 2 462 is hinged to the fixed plate 45 through a pin shaft, and the piston rod end of the cylinder 2 462 is hinged to the adjustment plate 461 through a pin shaft.

[0026] Specific implementation and principle:

[0027] S1, placing the valve 5 on the ball 35 at the top of the fixed column 2 through the groove on the valve plate inside the valve 5 for positioning;

[0028] S2. Next, turn on the air pump, and the gas enters the bottom tube 33 through the air passage in the fixed column 2 and the fixed ring 32, and drives the push tube 343 in the telescopic tube 34 to drive the telescopic tube 34 to extend from the bottom tube 33, and sprays the gas toward the valve 5 through the air outlet 341 on the telescopic tube 34. At the same time, the gas is blown toward the valve 5 through the drive tube 31 on the side of the fixed column 2, driving the valve 5 to rotate on the ball 35, and blowing and cleaning the impurities on the upper surface of the valve 5;

[0029] S3. When the surface of the valve 5 is cleaned, the air pump is turned off, the telescopic tube 34 is retracted into the bottom tube 33, and the valve 5 stops rotating;

[0030] S4, then, the piston rod of the control cylinder 1 41 is extended to drive the lifting frame 42 and the nozzle 47 to move down to a suitable position;

[0031] S5. Then, the piston rod of the control cylinder 2 462 drives the adjustment plate 461 to rotate, so that the nozzle 47 rotates to the corresponding position, and the powder coating is sprayed from the nozzle 47 to the valve 5 through the feed pump. At the same time, the gear 2 481 on the output shaft of the motor 48 drives the nozzle 47 on the gear 1 44 to rotate, and the valve 5 is sprayed.

[0032] To summarize, the present application positions the valve 5 through the ball 35 on the cleaning mechanism 3, and then sprays gas toward the valve 5 through the bottom tube 33 and the telescopic tube 34. At the same time, the driving tube 31 on the side of the fixed column 2 rotates the valve 5 on the ball 35 of the fixed column 2, thereby blowing and cleaning the impurities on the surface of the valve 5.
