The slide bar 15 is fixedly connected to the movable block 13. When the first gear 10 rotates, it will drive the slide bar 15 to make a circular motion. The slide bar 15 will squeeze the inner wall of the second slide groove 14, thereby driving the cross plate 7 to swing back and forth. The cross plate 7 finally drives the fan-shaped gear 6 to rotate back and forth. The internal rotation of the operating table 1 is connected with a rotating rod 16. The top of the rotating rod 16 is fixedly connected with a rotating disk 17. A clamping assembly is provided on the rotating disk 17. By screwing the screw, the clamping plate can be driven to clamp the plastic part placed on the rotating disk 17. The outside of the rotating rod 16 is fixedly connected with a second gear 18. The second gear 18 is meshed with the first gear 10. The motor 9 drives the first gear 10 to rotate. The first gear 10 cooperates with the second gear 18 to drive the rotating rod 16 to rotate. The rotating rod 16 will most drive the rotating disk 17 and the plastic part placed on the rotating disk 17 to rotate, so as to achieve the purpose of fully spraying paint on the plastic parts.

[0023] A paint box 19 is fixedly connected to the top of the operating table 1, and a paint pump 20 is fixedly connected to the top of the operating table 1 and on one side of the paint box 19. The feed port of the paint pump 20 is connected to the paint box 19 through a pipeline, and the discharge port of the paint pump 20 is connected to the paint nozzle 4 through a pipeline. The pipeline connecting the discharge port of the paint pump 20 and the paint nozzle 4 is a telescopic hose, which will not affect the back and forth movement of the paint nozzle 4. The paint pump 20 draws out the paint in the paint box 19 and transports it to the paint nozzle 4, and finally sprays it onto the plastic parts for surface painting of the plastic parts.

[0024] A guide rod 21 is slidably connected inside the vertical plate 3 , and the guide rod 21 is fixedly connected to the operating table 1 . The guide rod 21 limits the vertical plate 3 so that the vertical plate 3 can only move back and forth in the first sliding groove 2 .

[0025] A control panel 22 is fixedly connected to the outside of the operating table 1, and the motor 9 and the paint pump 20 are electrically connected to the control panel 22. The electrical equipment is powered by an external power supply, and the motor 9 and the paint pump 20 are controlled by the control panel 22. The above is an existing well-known technology and will not be elaborated on here.

[0026] The lower surface of the movable block 13 fits with the upper surface of the first gear 10, and the movable block 13 is slidably connected with the first gear 10. The lower surface of the movable block 13 fits with the upper surface of the first gear 10 to limit the movable block 13. When the user screws the threaded rod 12, the movable block 13 is limited, so that the rotating threaded rod 12 can drive the movable block 13 to move on the first gear 10, thereby adjusting the distance between the slide bar 15 on the movable block 13 and the center of the first gear 10, thereby changing the amplitude of the horizontal plate 7 to swing back and forth through the second slide groove 14 and the slide bar 15 when the first gear 10 rotates, thereby changing the angle of each rotation of the fan gear 6, cooperating with the rack 5 to change the range of the paint nozzle 4 on the vertical plate 3 driven by the rack 5 to move back and forth, so as to achieve the purpose of adjusting the position of the paint nozzle 4 moving back and forth for plastic parts of different sizes.

[0027] The outer wall of the vertical plate 3 fits with the inner wall of the first chute 2, which can prevent the vertical plate 3 from tipping over and ensure that the paint nozzle 4 on the vertical plate 3 is always facing the rotating disk 17.

[0028] The utility model uses the following steps: When the surface treatment equipment for engineering plastics is in use, the plastic parts are placed on the rotating disk 17, and after clamping, the motor 9 is started through the control panel 22 to drive the first gear 10 to rotate, and the first gear 10 drives the rotating rod 16 to rotate through the second gear 18, and the rotating rod 16 drives the rotating disk 17 and the plastic parts on the rotating disk 17 to rotate. When the first gear 10 rotates, it drives the slide bar 15 to make a circular motion. During the process, the slide bar 15 squeezes the inner wall of the second slide groove 14, driving the horizontal plate 7 to swing back and forth, and the horizontal plate 7 drives the fan gear 6 to rotate back and forth. Finally, the fan gear 6 drives the vertical plate 3 and the paint nozzle 4 on the vertical plate 3 to move back and forth through the rack 5, and the paint pump 20 is started to pump the paint in the paint box 19 to the paint nozzle 4 , the paint nozzle 4 sprays the paint onto the plastic parts. Since the plastic parts rotate with the rotating disk 17, the back and forth movement of the paint nozzle 4 can achieve the purpose of spraying paint on the surface of the plastic parts in an all-round manner, and the paint spraying is uniform. For plastic parts of different sizes, if the range of back and forth movement of the paint nozzle 4 is too large, the sprayed paint cannot be effectively sprayed onto the surface of the plastic parts with smaller volumes. The threaded rod 12 on the first gear 10 can be screwed after the machine is stopped to control the movable block 13 to drive the sliding rod 15 to move toward the center of the first gear 10. At this time, the first gear 10 rotates again to drive the horizontal plate 7 to swing back and forth, and the amplitude will be reduced. Correspondingly, the range of back and forth movement of the vertical plate 3 and the paint nozzle 4 will also be reduced, thereby improving the adaptability of the equipment.
