Description

Technical Field

[0001] The invention relates to the technical field of sculpture coloring, and in particular to a device for coloring the surface of a sculpture and a method of using the device. Background Art

[0002] Sculptures made of gypsum, cement, and fiberglass often lack artistic appeal due to their lack of individuality. They often need to have artificial textures on their surfaces or use coloring methods to imitate the texture of other materials in order to change the visual effect and enhance the aesthetic value.

[0003] Application number: 2023207035951, discloses a sculpture surface uniform coloring treatment device, through the arrangement of a nozzle, a curved pipe, a support arm, a rotating motor and a conduit, the conduit is used to guide the paint on the inner wall of the liquid storage tank into the inner wall of the curved pipe, and then the paint is transmitted to the inner wall of the nozzle through the curved pipe, the nozzle is used to spray the paint on the sculpture, and the rotating motor drives the support arm to perform universal rotation, which is convenient for changing the position angle of the nozzle. The sculpture is more evenly colored, and the dead corners are easy to color, which improves work efficiency, thereby achieving the best use effect.

[0004] Although this design enables circumferential coloring around the sculpture, the pipe rotates around the sculpture, causing the distance between the nozzle and the sculpture surface to change constantly, making it impossible to ensure uniform coloring at each location, resulting in overspraying in some areas and underspraying in others. In addition, the height limit of the pipe limits the spraying to the upper half of the sculpture, failing to reach the bottom and lower areas, further leading to uneven coloring. Therefore, this design is not suitable for all types of sculptures, especially those that require uniform coloring all around. Summary of the invention

7. The device for coloring the surface of a sculpture according to claim 1, characterized in that: Two mounting rods (31) are arranged in the placement box (13), a connecting plate (12) is arranged on the two mounting rods (31), springs (38) are arranged on the two mounting rods (31), one end of the two springs (38) is connected to the side of the connecting plate (12), one end of the two springs (38) away from the connecting plate (12) is connected to the side wall of the placement box (13), the connecting plate (12) is connected to a plurality of support rods (29) at equal intervals, one end of the support rods (29) passes through the side wall of the placement box (13) and is connected to a fixing seat (43), and the brush (25) is connected to the fixing seat (43).

8. The device for coloring the surface of a sculpture according to claim 6, characterized in that: Two fixing plates (7) are connected to the top plate (6), and the fixing plates (7) and the supporting plates (8) are connected via first connecting ribs.

9. A method for using a device for coloring the surface of a sculpture, characterized in that: The device for coloring the sculpture surface according to claim 6 comprises the following steps: S1: The bracket (1) drives the two support seats (4) to move so that the sculpture is located between the two support seats (4), the hydraulic cylinder (9) drives the moving seat (2) to move, and the moving seat (2) drives the two support seats (4) to move to the top of the sculpture; S2: The first motor (46) drives the first active bevel gear (39) to rotate, and the first active bevel gear (39) drives the first driven bevel gear (40) to rotate, thereby controlling the forward and reverse threaded rods (44) to rotate, and the forward and reverse threaded rods (44) control the two support seats (4) to move toward the sculpture, so that the spray gun (28) is first aimed at the position of the sculpture that needs to be colored; S3: At this time, the spray gun (28) starts to spray paint on the sculpture, and at the same time, the second motor (20) drives the disc (34) to rotate. The disc (34) drives the adjustment plate (16) to move up and down through the adjustment rod (33). The adjustment plate (16) drives the push rod (11) to move up and down. When the push rod (11) moves up and down, it will move the two movable plates (14) left and right through the corresponding connecting rod (10). The movable plate (14) drives the spray gun (28) to move together, so that the sculpture is evenly sprayed with paint. At the same time, the movable plate (14) also drives the brush (25) to move to apply paint to the colored position; S4: The second motor (20) drives the toothed disc (18) to rotate, and the teeth on the toothed disc (18) mesh with the two gears (19) respectively, so that the sleeve (22) rotates in the forward and reverse directions respectively, and the sleeve (22) drives the second active bevel gear (41) to rotate through the moving rod (23), and the second active bevel gear (41) drives the second driven bevel gear (42), and the second driven bevel gear (42) drives the forward and reverse rotating plate (27) to rotate through the transmission shaft (26), and the rotating plate (27) controls the angle of the spray gun (28), so that the pigment is more evenly distributed on the surface of the sculpture; S5: The hydraulic cylinder (9) controls the movable seat (2) to move downward, and the spray gun (28) gradually sprays paint on the lower part of the sculpture.
