Therefore, under the action of the casters 2 and the handle 3, the base 1 can be conveniently pushed and moved, that is, the spraying device can be conveniently pushed and moved by the user. One end of the top of the base 1 near the handle 3 is fixedly provided with a paint can 4. The user can add the paint required for spraying and processing the outer surface of the advertising signboard into the paint can 4 through a feed port (not marked in the figure). The bottom end of the side of the paint can 4 is fixedly communicated with a discharge pipe 5. A stop valve 6 is fixed on the pipe body of the discharge pipe 5. A stirring assembly is fixed on the paint can 4. The end of the discharge pipe 5 is fixedly communicated with a spraying assembly. One end of the top of the base 1 away from the handle 3 is fixedly provided with an adjusting assembly. The spraying assembly is fixedly connected with the adjusting assembly;

[0022] The stirring assembly includes a speed reducer 7. It should be noted that a speed reducer is a transmission device for low-speed and high-torque. The power of the high-speed operation of the motor is reduced by the meshing of the gear with fewer teeth on the input shaft of the speed reducer and the large gear on the output shaft. The bottom of the speed reducer 7 is fixed at the center of the top of the paint tank 4. A stirring motor 8 is fixed on the top of the speed reducer 7. The output shaft of the stirring motor 8 is fixedly connected to the input shaft of the speed reducer 7. The output shaft of the speed reducer 7 vertically penetrates the top of the paint tank 4, and a stirring paddle 9 is fixed on the output shaft of the speed reducer 7. That is, under the deceleration effect of the speed reducer 7, when the stirring motor 8 operates, it can drive the stirring paddle 9 to slowly rotate in the paint tank 4, so as to stir the paint added to the paint tank 4, which is beneficial to keep the paint fluid. The stirring paddle 9 is located in the paint tank 4. Connecting plates 10 are symmetrically fixed at the ends of the stirring paddle 9. Rubber scraping plates 11 are fixed on the surfaces of the connecting plates 10. The surfaces of the rubber scraping plates 11 are all in contact with the side wall of the inner wall of the paint tank 4. Specifically, when the stirring motor 8 operates to drive the stirring paddle 9 to slowly rotate, it can drive the rubber scraping plates 11 to rotate synchronously through the connecting plates 10, so that the rubber scraping plates 11 can scrape the side wall of the inner wall of the paint tank 4, effectively preventing the paint from adhering to the side wall of the inner wall of the paint tank 4;

[0023] The spraying assembly includes a material pumping pump 12. The bottom of the material pumping pump 12 is fixed on the top of the base 1. The input end of the material pumping pump 12 is fixedly connected with a material pumping pipe 13. The end of the material pumping pipe 13 is fixedly connected with the end of the discharge pipe 5.

The top end of the material conveying hose 14 is fixedly communicated with a material conveying pipe 15. A spray head 16 is fixed at the end of the material conveying pipe 15. Specifically, when the stop valve 6 is opened and the material pumping pump 12 operates, the paint in the paint tank 4 can be pumped out through the discharge pipe 5, then pumped into the material conveying pipe 15 through the material conveying hose 14, and then sprayed out through the spray head 16, so as to achieve the effect of spraying the outer surface of the advertising sign;

[0024] The adjusting assembly includes a vertically arranged electric push rod 17. It should be noted that an electric push rod is a power-driven device that converts the rotary motion of a motor into the linear reciprocating motion of a push rod. The bottom of the electric push rod 17 is fixed at one end of the top of the base 1 away from the handle 3. The top end of the output shaft of the electric push rod 17 is horizontally fixed with a lifting plate 18. Specifically, when the electric push rod 17 operates, it can drive the lifting plate 18 to lift and adjust;

[0025] A moving base 19 is horizontally fixed at the top of the lifting plate 18. That is, the moving base 19 can be lifted and adjusted synchronously with the lifting plate 18. A servo motor 20 is fixed at the side end of the moving base 19. The output shaft of the servo motor 20 penetrates through the end of the moving base 19, and a lead screw 21 is fixed to the output shaft of the servo motor 20. A moving sleeve 22 is threadedly connected to the surface of the lead screw 21. A limiting slide plate 23 is vertically fixed to the top of the moving sleeve 22. A strip-shaped limiting slide hole 24 is formed at the top of the moving base 19. The top end of the limiting slide plate 23 vertically penetrates through the strip-shaped limiting slide hole 24, and the surface of the limiting slide plate 23 is in contact with the hole wall of the strip-shaped limiting slide hole 24. A moving plate 25 is horizontally fixed to the top end of the limiting slide plate 23. Specifically, under the combined limiting action of the limiting slide plate 23 and the strip-shaped limiting slide hole 24, when the servo motor 20 operates to drive the lead screw 21 to rotate forward and backward in the moving base 19, the moving sleeve 22 threadedly connected to the surface of the lead screw 21 can move linearly back and forth, thereby driving the moving plate 25 to move linearly back and forth synchronously.

[0026] A support rod 26 is vertically fixed to the top of the moving plate 25. The top end of the support rod 26 is fixed to the bottom of the material conveying pipe 15. Specifically, when the servo motor 20 operates to control the linear reciprocating movement of the moving plate 25, the material conveying pipe 15 can be driven to move linearly back and forth synchronously through the support rod 26, that is, the spray head 16 can be controlled to move linearly back and forth, so as to realize the function of adjusting the spraying position of the spray head 16. And when the electric push rod 17 operates to drive the lifting plate 18 to lift and adjust, the material conveying pipe 15 can be driven to lift and adjust synchronously, so as to control the lifting adjustment of the spray head 16, and the function of adjusting the spraying height of the spray head 16 can be realized. Therefore, it can be well applied to the spraying processing of the outer surfaces of advertising signs of different sizes, and has a wide application range.

[0027] It should be noted that this device is electrically connected to an external main controller and 220V mains electricity, and the main controller can be an existing technical device such as a computer that plays a control role.

[0028] The use process of the present utility model is as follows: The user first pushes the spraying device to the required position, then adds the paint required for the spraying processing of the outer surface of the advertising sign into the paint tank 4 through the feed port, and turns on the stirring motor 8 to control the stirring paddle 9 to stir the paint in the paint tank 4. Then, the feeding pump 12 is operated to pump out the paint and spray it through the spray head 16, so as to realize the function of spraying the outer surface of the advertising sign. During the spraying process, the user can operate the electric push rod 17 and the servo motor 20 to control the linear reciprocating movement and lifting adjustment of the spray head 16, so as to realize the function of adjusting the spraying position and spraying height of the spray head 16. Therefore, it can be well applied to the spraying processing of the outer surfaces of advertising signs of different sizes, and has a wide application range.

[0029] The above are only the preferred embodiments of the present utility model.
