[0025] As Figures 1 to 4 shown, an embodiment of the present utility model provides a device for coloring the surface of a billboard, including a placement rack 1:

[0026] Three groups of vertical double rods 2 are symmetrically arranged at the top of the placement rack 1. Sliding sleeves 4 are slidably arranged on the outer walls of the vertical double rods 2. A connecting frame 6 is fixedly arranged between the two sliding sleeves 4. A central axis seat 12 is fixedly arranged on one side of each connecting frame 6. A first rotating shaft 13 is rotatably arranged inside the central axis seat 12. A first U-shaped seat 14 is fixedly arranged at one end of the first rotating shaft 13. An auxiliary connecting rod 15 is rotatably arranged inside each of the two first U-shaped seats 14. The bottom ends of the two auxiliary connecting rods 15 are rotatably connected to the inside of the corresponding second U-shaped seat 16. One end of each of the two second U-shaped seats 16 is fixedly connected to one end of a second rotating shaft 8. The second rotating shaft 8 is rotatably connected to the inside of the corresponding fixing frame 10. The three fixing frames 10 are evenly distributed at the edge position of the outer wall of the middle plate 9.

[0027] Specifically, the bottom ends of the vertical double rods 2 are fixedly connected to the bottom end of the top seat 3. A servo motor 5 is fixedly arranged at the top end of the top seat 3. The output end of the servo motor 5 is fixedly connected to the top end of the lead screw 7. The outer wall of the lead screw 7 is threadedly connected to the threaded hole at the middle position of the connecting frame 6.

[0028] Specifically, a paint spraying device 11 is arranged inside the middle plate 9.

[0029] Specifically, the three groups of vertical double rods 2 are arranged in a circumferential array, with an angular interval of 120 degrees.

[0030] Specifically, a switch panel is arranged on the placement rack 1. A servo motor switch is fixedly arranged on the surface of the switch panel. The servo motor 5 is electrically connected to an external power supply through the servo motor switch.

[0031] Working principle: When in use, place the billboard above the placement rack 1. When coloring a certain area of the billboard, turn on any one of the three servo motors 5. The output end of the servo motor 5 drives the corresponding lead screw 7 to rotate. The lead screw 7 is threadedly connected to the corresponding connecting frame 6, thereby driving the two sliding sleeves 4 to slide downward on the vertical double rods 2. During the downward sliding process, since the first U-shaped seat 14 and the second U-shaped seat 16 are rotatably connected to the corresponding auxiliary connecting rod 15, the paint spraying device 11 on the middle plate 9 can be pushed directly above the area of the billboard that needs to be painted with paint. To avoid paint splashing due to excessive height, the servo motors 5 can be turned on simultaneously. When the three groups of servo motors 5 are started simultaneously, the height of the paint spraying device 11 on the middle plate 9 can be adjusted.

[0032] Each embodiment in this specification is described in a progressive manner. For the same or similar parts among the embodiments, reference can be made to each other. Each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and for the relevant parts, reference can be made to the partial description of the method embodiment.

[0033] The above are only the embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
