[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides an automobile exterior primer spraying device, as Figure 1 、 Figure 2 and Figure 3 shown. The spraying device includes a workbench 1, a paint box 2 fixedly installed on the workbench 1, a plurality of spraying pipes 3 fixedly installed inside the paint box 2, a plurality of paint spraying heads 4 fixedly installed on the spraying pipes 3, a fixing block 5 fixedly installed on the workbench 1, and a flipping assembly arranged on the fixing block 5 for flipping the automobile exterior.

[0026] The flipping assembly includes a first redirecting piece 6 fixedly installed on the fixing block 5, a second redirecting piece 7 fixedly installed on the fixing block 5, a threaded block 9 slidably installed inside a groove on the fixing block 5, a flipping block 10 fixedly installed on the threaded block 9, a rotating rod 11 rotatably installed inside the flipping block 10, a gear 12 fixedly installed on the rotating rod 11, a limit pin 13 slidably installed on the workbench 1, and a rack 15 fixedly installed on the fixing block 5. The gear 12 meshes with the rack 15.

[0027] When the user sprays the primer on the exterior of the car, after placing the car exterior at a position that can be sprayed by the spray head 4, when the threaded block 9 moves forward, the forward movement of the threaded block 9 drives the flipping block 10 to move forward. The forward movement of the flipping block 10 drives the rotating rod 11 and the gear 12 inside the flipping block 10 to move forward. During the movement, the car exterior is sprayed by the spray head 4. When the gear 12 passes by the rack 15 fixedly installed on the fixed block 5, since the number of teeth on the rack 15 is half of the number of teeth on the gear 12, the gear 12 will rotate 180 degrees to turn over the car exterior. Then the threaded block 9 continues to drive the flipping block 10 to move forward. When the limit pin 13 touches the second deflecting piece 7, the limit pin 13 slides along the special-shaped groove opened on the second deflecting piece 7. As the pin 13 slides, it drives the rotating rod 11 to slide a certain distance, and the rotating rod 11 drives the gear 12 to slide a certain distance. Then when the threaded block 9 moves backward, the backward movement of the threaded block 9 drives the flipping block 10 to move backward. The backward movement of the flipping block 10 drives the rotating rod 11 and the gear 12 inside the flipping block 10 to move backward. Since the gear 12 slides a certain distance, the gear 12 will not touch the rack 15 during the backward movement, and the car exterior always remains in the reverse state and moves backward. The reverse side of the car exterior is sprayed by the spray head 4. When the limit pin 13 touches the first deflecting piece 6, the limit pin 13 slides reversely along the special-shaped groove opened on the first deflecting piece 6. As the pin 13 slides, it drives the rotating rod 11 to slide reversely a certain distance, and the rotating rod 11 drives the gear 12 to slide reversely a certain distance, returning to the initial state to prepare for spraying the next car exterior.

[0028] Further, to facilitate the movement of the threaded block 9, as Figure 1 、 Figure 2 and Figure 3 shown, a threaded rod 8 is rotatably connected inside the groove of the fixed block 5, and the threaded block 9 is screwed onto the threaded rod 8. One side of the fixed block 5 is fixedly connected with a motor 14, and the output end of the motor 14 is fixedly connected to the threaded rod 8.

[0029] When the user sprays the primer on the exterior of the car, by starting the motor 14, the output end of the motor 14 rotates forward. The forward rotation of the output end of the motor 14 drives the threaded rod 8 to rotate forward. The forward rotation of the threaded rod 8 drives the threaded block 9 to move forward. By the output end of the motor 14 rotating backward, the backward rotation of the output end of the motor 14 drives the threaded rod 8 to rotate backward. The backward rotation of the threaded rod 8 drives the threaded block 9 to move backward.

[0030] Even further, to clamp and fix the car exterior, asFigure 1 , Figure 4 and Figure 5 As shown in Figure 1 , Figure 4 and Figure 5 , a fixing frame 16 is fixedly connected to one end of the rotating rod 11 away from the gear 12. A plurality of springs 17 are fixedly connected inside the fixing frame 16. Two baffles 18 are slidably connected inside the chute on the fixing frame 16. One end of the spring 17 away from the fixing frame 16 is fixedly connected to the baffle 18.

[0031] By manually placing the automotive exterior in the fixing frame 16, the resilience of the spring 17 drives the two baffles 18 to move towards each other, thereby fixing the automotive exterior. When removing the automotive exterior, the two baffles will return to their initial positions.

[0032] Among them, in order to recycle the paint, as Figure 1 , Figure 3 and Figure 5 shown, a paint storage tank 19 is fixedly connected to the bottom of the workbench 1, and a water pump 20 is fixedly connected to one side of the paint storage tank 19.

[0033] A liquid delivery pipe 21 is fixedly connected to the water pump 20, and a liquid distribution pipe 22 is fixedly connected to the liquid delivery pipe 21. The inner cavity of the liquid distribution pipe 22 is connected to the inner wall of the liquid delivery pipe 21.

[0034] A plurality of spraying pipes 3 are fixedly connected to the liquid distribution pipe 22, and the inner cavity of the liquid distribution pipe 22 is connected to the spraying pipes 3.

[0035] Before the user sprays the primer on the automotive exterior, the paint is poured into the paint storage tank 19. When spraying the primer on the automotive exterior, by starting the water pump 20, the paint in the paint storage tank 19 is pumped into the liquid delivery pipe 21, and then flows into the liquid distribution pipe 22. The paint is evenly distributed into each spraying pipe 3 through the liquid distribution pipe 22, and then the paint is sprayed onto the automotive exterior through the paint spraying head 4. The paint that is not sprayed onto the automotive exterior by the paint spraying head 4 flows back into the paint storage tank 19 through the opening provided on the workbench 1.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
