Description
Technical Field
[0001] This utility model belongs to the field of plastic prototype technology, specifically a plastic prototype model spraying device. Background Technology
[0002] With the acceleration of product development and the trend towards more refined surface finishes, the prototype model industry has placed higher demands on the efficiency and quality of spraying. Traditional manual spraying is inefficient and inconsistent, and small-batch production scenarios require the adaptation to automated equipment, which drives the development of dedicated spraying devices.
[0003] Traditional manual spraying relies on experience and has drawbacks such as low efficiency, unstable quality, and environmental hazards. Early industrial spraying equipment was also unable to meet the needs of multi-shaped, small-batch spraying of prototype models due to its large size, complex debugging, and high paint waste rate.
[0004] Traditional manual spraying relies on experience and has drawbacks such as low efficiency, unstable quality, and environmental hazards. Early industrial spraying equipment was also unable to meet the needs of multi-shaped, small-batch spraying of prototype models due to its large size, complex debugging, and high paint waste rate.
[0005] Therefore, this utility model provides a plastic hand model spraying device. Utility Model Content

The top of the inner wall of the rotating disk is fixedly mounted to the rotating rod. The geared motor is fixedly mounted on the top of the L-shaped support frame near the rotating rod, and the output end of the geared motor is fixedly mounted to the rotating rod. The combined use of the rotating disk, rotating rod, and geared motor enables rotation, allowing the user to fix the handpieces sequentially. Furthermore, the rotation of the rotating disk allows workers to place multiple handpieces from a single position, reducing space requirements and labor consumption.

The end of the spring away from the first L-shaped clamp is fixedly installed with the push plate. The side of the push plate away from the spring is fixedly installed with the second anti-slip pad. In this scheme, the combined use of the spring, the push plate, and the second anti-slip pad can clamp the hand plate with the pushing force of the spring, so that it can remain stable and prevent loosening during the spraying process.
[0010] Preferably, the adjustment mechanism includes a shaft frame, a stepper motor, and a storage tank.

[0011] Preferably, the spraying assembly includes partitions and spray nozzles. Several sets of partitions are arranged in a ring and fixedly installed on the inner wall of the storage tank. Several sets of spray nozzles are arranged in a ring and fixedly installed on the surface of the storage tank. In this scheme, the partitions can isolate the space inside the storage tank, so that various colors can be stored in the storage tank. The spray nozzles can spray the pigments inside the storage tank onto the hand plate.
[0012] Preferably, the filling assembly includes an isolation cylinder and a conveying pipe. The isolation cylinder is fixedly installed on the inner wall of the storage tank and is fixedly installed with a partition. Several sets of conveying pipes are provided, and the several sets of conveying pipes are fixedly installed in a ring on the inner wall of the isolation cylinder. The conveying pipes pass through the isolation cylinder to the inner wall of the storage tank. In this scheme, the combined use of the isolation cylinder and the conveying pipes can realize the filling of the inside of the storage tank. At the same time, the design of multiple sets of conveying pipes can prevent color mixing during filling.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. The plastic hand model spraying device of this utility model, through the arrangement of a rotating disk, a rotating rod and a reduction motor, enables the rotating disk, rotating rod and reduction motor to rotate so that the user can fix the hand model in sequence. At the same time, because the rotating disk rotates, the worker only needs to stand in one position to place multiple hand models, reducing the activity space and labor consumption.

The rotating disk 41 is rotatably mounted on the top of the operating table 2 away from the L-shaped support frame 3. The top of the inner wall of the rotating disk 41 is fixedly mounted to the rotating rod 42. The reduction motor 43 is fixedly mounted on the top of the L-shaped support frame 3 near the rotating rod 42, and the output end of the reduction motor 43 is fixedly mounted to the rotating rod 42. The clamping mechanism 5 includes a first L-shaped clamping plate 51, a second L-shaped clamping plate 52, and a first anti-slip pad 53. The first L-shaped clamping plate 51 and the second L-shaped clamping plate 52 are each provided with several sets. Several sets of first L-shaped clamping plates 51 are fixedly mounted in a ring on the surface of the rotating disk 41, and several sets of second L-shaped clamping plates 52 are fixedly mounted in a ring on the inner wall of the rotating disk 41. The inner side of the clamping plate 52 is fixedly installed with the first anti-slip pad 53. The tightening mechanism 6 includes a spring 61, a push plate 62, and a second anti-slip pad 63. The spring 61 is fixedly installed on the side of the first L-shaped clamping plate 51 near the second L-shaped clamping plate 52. The end of the spring 61 away from the first L-shaped clamping plate 51 is fixedly installed with the push plate 62. The side of the push plate 62 away from the spring 61 is fixedly installed with the second anti-slip pad 63. The adjusting mechanism 7 includes a shaft frame 71, a stepper motor 72, and a storage tank 73. The shaft frame 71 is fixedly installed on the top of the inner wall of the L-shaped support frame 3. One side of the shaft frame 71 is fixedly installed with the stepper motor 72. The inner wall of the shaft frame 71 is fixedly installed with the storage tank 73. The stepper motor 72... The output end is fixedly installed with the storage tank 73. The spraying assembly 8 includes a partition 81 and a nozzle 82. Several sets of partitions 81 are provided and are fixedly installed in a ring on the inner wall of the storage tank 73. Several sets of nozzles 82 are provided and are fixedly installed in a ring on the surface of the storage tank 73. The filler assembly 9 includes an isolation cylinder 91 and a conveying pipe 92. The isolation cylinder 91 is fixedly installed on the inner wall of the storage tank 73 and is fixedly installed with the partition 81. Several sets of conveying pipes 92 are provided and are fixedly installed in a ring on the inner wall of the isolation cylinder 91. The conveying pipe 92 passes through the isolation cylinder 91 to the inner wall of the storage tank 73.
[0027] like Figures 1 to 5As shown, the combined use of the rotating disk 41, rotating rod 42, and reduction motor 43 enables rotation, allowing the user to fix the handpiece sequentially. Simultaneously, the rotation of the rotating disk 41 allows workers to place multiple handpieces from a single position, reducing space requirements and labor consumption. The combined use of the first L-shaped clamp 51 and the second L-shaped clamp 52 clamps the handpiece, ensuring it fits perfectly inside the clamps. The first anti-slip pad 53 prevents the handpiece from slipping during painting. The combined use of the spring 61, push plate 62, and second anti-slip pad 63 uses the pushing force of the spring 61 to press the handpiece firmly, maintaining its position. To ensure stability and prevent loosening during the spraying process, the shaft bracket 71 provides stable support for the stepper motor 72 and the storage tank 73. The combined use of the stepper motor 72 and the storage tank 73 allows the orientation of different color nozzles 82 to be adjusted by rotating the storage tank 73, enabling different colors to be sprayed on the prototype and improving its appearance. The partition 81 isolates the internal space of the storage tank 73, allowing various colors to be stored in the storage tank 73. The nozzles 82 spray the pigment inside the storage tank 73 onto the prototype. The combined use of the isolation cylinder 91 and the feed pipe 92 allows for filling the inside of the storage tank 73. At the same time, the design of multiple feed pipes 92 prevents color mixing during filling.
[0028] Working principle: During operation, first place the base plate 1 on a flat surface, then start the reduction motor 43 to drive the rotating rod 42 to rotate. The rotation of the rotating rod 42 will drive the rotating disk 41 to rotate slowly. After the rotating disk 41 rotates, the user places the hand-shaped model into the first L-shaped clamp 51. When placing it, the user must first hold the hand-shaped model, then place it in the gap between the push plate 62 and the second L-shaped clamp 52, and press down to widen the opening. At the same time, the spring 61 will be compressed. The user then pushes the hand-shaped model towards the push plate 62 so that the entire hand-shaped model can be horizontally fixed within the first L-shaped clamp 51 and the second L-shaped clamp 52. When the hand-shaped model moves to below the storage tank 73, the stepper motor 72 needs to be started to drive the storage tank... The material tank 73 rotates, causing the nozzle 82 to face the handpiece downwards. At this time, the nozzle 82 is activated to spray the paint inside the material tank 73 onto the handpiece. The user can rotate the material tank 73 to spray the handpiece with the nozzle 82 at different positions, thereby achieving different colors. When it is necessary to load the material, the user needs to connect the material delivery pipe 92 to the raw material and transport the raw material of different colors into the material tank 73 through the material delivery pipe 92. Since there are partitions 81 inside the material tank 73, the colors will not mix. The user can increase or decrease the number of partitions 81 to increase the amount of color that the material tank 73 can store, thereby increasing the color richness of the handpiece after spraying.
