[0043] Working principle: first place the auto parts on the placement table 6, cover the box cover 2, then start the synchronous electric telescopic rod 7, fix the auto parts in the center on the placement table 6, then start the motor 5, so that the placement table 6 drives the auto parts to rotate together, and then start the electric threaded rod 10 to move the turntable 1 9 toward the turntable 2 11, prompting the swivel 8 to rotate, driving the slider 15 to move toward the shaft 14, and the push rod 19 pushes the piston plate 18 to move toward the shaft 14, so that the liquid inside the piston box 17 is sprayed on the auto parts through the nozzle 24, and at the same time the cleaning roller 12 moves toward the auto parts on the placement table 6, and the auto parts are washed because they are rotating.

[0044] When washing is completed, the electric threaded rod 10 is rotated in the reverse direction to make the turntable 1 9 move away from the turntable 2 11, so as to cause the swivel 8 to rotate in the reverse direction, drive the slider 15 to move toward the cleaning roller 12, and the push rod 19 pulls the piston plate 18 to move toward the cleaning roller 12, so that the liquid in the liquid storage tank 4 is sucked into the piston box 17, and the cleaning roller 12 is also away from the automobile parts on the placement table 6. Then the hot air blower is started, and the hot air passes through the ventilation hose 27 and the duct 23 and is sprayed out through the nozzle 24, so as to dry the cleaned automobile parts.

[0045] After the drying is completed, the hot air blower is turned off, and the booster pump in the storage box 25 is started, so that the paint therein passes through the paint hose 26 and the conduit 23 and is sprayed out through the nozzle 24, thereby spraying the automobile parts. After the spraying is completed, the booster pump is turned off, and the hot air blower is started again to dry the sprayed automobile parts. After the drying is completed, the hot air blower and the motor 5 are turned off, the sprayed and dried automobile parts are taken out, and then the electric threaded rod 10 is started again to squeeze the liquid in the piston box 17 to the conduit 23 and the nozzle 24 again and then spray it out, thereby cleaning the sprayed conduit 23 and the nozzle 24.
