When the workpiece moves with the second conveyor belt 23 and enters the drying box 25, the drying box 25 dries the outer wall of the workpiece.

[0035] By providing the nozzle 24 and the drying box 25, after the workpiece is cleaned, the surface and inner wall of the workpiece are dried, so as to facilitate the subsequent transportation or processing of the workpiece.

[0036] Working principle: During operation, the workpiece is placed on the first conveyor belt 1, and the workpiece moves with the first conveyor belt 1. The outer surface of the workpiece is cleaned through the nozzle 5, and the waste water generated by the cleaning flows into the water collecting tank 4 through the water permeable hole 6. The positioning rod 7 limits the workpiece during the movement of the workpiece. Since the positioning rod 7 is divided into two sections and is staggered, the part of the workpiece blocked by the positioning rod 7 will change during the cleaning process, so that the surface of the workpiece is fully cleaned. After the workpiece moves to one end of the first conveyor belt 1, it will be pushed into the limiting groove 9. When the workpiece completely enters the limiting groove 9, the electric turntable 8 drives the workpiece to rotate 90 degrees. At this time, the workpiece faces the second conveyor belt 23, and then the motor 14 starts , so that the moving block 15 moves along the slide groove 12, at this time, the push plate 16 moves with the moving block 15 and drives the connecting frame 18 to move through the push plate 16, so that the fixed column 21 is inserted into the workpiece, and the nozzle 22 cleans the inner wall of the workpiece. The nozzle 24 moves with the fixed column 21, and pushes the water on the inner wall of the workpiece to one side through the air flow to remove the water attached to the inside of the workpiece. When the connecting frame 18 moves a certain distance, the connecting frame 18 is limited by the positioning groove 17 and stops moving. The moving block 15 continues to drive the push plate 16 to move forward, pushing the workpiece out of the limiting groove 9 and falling on the surface of the second conveyor belt 23. When the workpiece moves with the second conveyor belt 23 and enters the drying box 25, the drying box 25 dries the outer wall of the workpiece.
