Figure 1 As shown, it includes a base frame 3, a spraying bracket 4 and an aluminum ring bracket 1. The spraying bracket 4 is detachably installed on the top of the base frame 3. The aluminum ring bracket 1 is rotatably installed at the center of the upper surface of the base frame 3. The spraying bracket 4 is an annular structure. Movable brackets 8 are installed on both sides above the spraying bracket 4. One end of the movable bracket 8 faces the center of the spraying bracket 4. A U-shaped spray plate frame 11 for spraying is installed on the end of the movable bracket 8 facing the center of the spraying bracket 4. A plurality of spray heads are evenly distributed on the inner side of the U-shaped spray plate frame 11. A spray pipe 6 is inserted on one side of the spraying bracket 4.

[0026] A first motor 2 is installed at the bottom center of the bottom frame 3 , and an output shaft of the first motor 2 passes through the bottom frame 3 and is connected to the bottom of the aluminum ring bracket 1 .

[0027] A fixed plug plate 5 is installed on the front surface of the spray bracket 4 , and the spray pipe 6 passes through the fixed plug plate 5 .

[0028] By adopting the above technical solution:

[0029] In the device, the aluminum ring bracket 1 is rotatably mounted at the center of the upper surface of the bottom plate frame 3, and a first motor 2 is mounted at the bottom center of the bottom plate frame 3. The output shaft of the first motor 2 passes through the bottom plate frame 3 and is connected to the bottom of the aluminum ring bracket 1, so that when the aluminum ring is installed, the bottom plate frame 3 can be rotated by controlling the first motor 2, which facilitates the installation of the aluminum ring;

[0030] The device used for spraying the aluminum ring in the device is a U-shaped spray plate frame 11, and a plurality of spray heads are evenly distributed on the inner side of the U-shaped spray plate frame 11. Such a spraying structure arrangement enables the U-shaped spray plate frame 11 to half-wrap the aluminum ring in a ring shape when the device is spraying the aluminum ring, making the aluminum ring more comprehensive and convenient to spray.

[0031] Embodiment 2:

[0032] This embodiment provides a specific structure of a spray coating device for processing bicycle aluminum rims. Figure 1 As shown, the aluminum rim bracket 1 is a U-shaped structure, and a dynamic clamp 16 and a fixed clamp 17 for clamping the bicycle aluminum rim are installed on the inner side above the two vertical ends of the aluminum rim bracket 1.

[0033] A hydraulic cylinder 15 and a third motor 18 are installed on the upper outer side of the aluminum ring bracket 1. The hydraulic cylinder 15 is located on the side of the aluminum ring bracket 1 close to the dynamic clamp 16. The free end of the piston rod of the hydraulic cylinder 15 is rotatably connected to one side of the dynamic clamp 16 through a bearing. The third motor 18 is located on the side of the aluminum ring bracket 1 close to the fixed clamp 17. The output shaft of the third motor 18 is connected to one side of the fixed clamp 17.

[0034] By adopting the above technical solution:

[0035] The aluminum rim bracket 1 is a U-shaped structure, and a dynamic clamp 16 and a fixed clamp 17 for clamping the bicycle aluminum rim are arranged on the inner side of the aluminum rim bracket 1, wherein the dynamic clamp 16 can be horizontally moved by the control of the hydraulic cylinder 15, so that the distance between the dynamic clamp 16 and the fixed clamp 17 can be changed, so that the device can be suitable for fixed spraying of aluminum rims of different widths. When the third motor 18 is running, it can drive the aluminum rim to rotate on the aluminum rim bracket 1. Such a structural setting makes the spraying device more uniform during spraying, thereby improving the spraying quality.

[0036] Embodiment 3:

[0037] This embodiment provides a specific structure of a spray coating device for processing bicycle aluminum rims. Figure 1As shown, a first U-shaped groove 12 is opened at one end of the movable bracket 8, and a second U-shaped groove 13 is opened at the other end of the movable bracket 8. The U-shaped spray plate rack 11 is fixed to the inner wall of the first U-shaped groove 12, and the opening of the U-shaped spray plate rack 11 coincides with the opening of the first U-shaped groove 12. The second U-shaped groove 13 is clamped on the spray bracket 4, and the spray bracket 4 is rotatably connected to one end of the movable bracket 8 through a rotating shaft 14.

[0038] A second motor 10 is installed on the top of the spraying bracket 4. The output shaft of the second motor 10 is connected to the rotating shaft 14 through a transmission belt 9. One end of the rotating shaft 14 is also provided with a blocking plate 7 to prevent the transmission belt 9 from slipping.

[0039] There are two movable brackets 8 in total, and the rotating shafts 14 on the two movable brackets 8 are both transmission-connected to the second motor 10 . The two movable brackets 8 are symmetrical to each other about the vertical center line of the spraying bracket 4 .

[0040] By adopting the above technical solution:

[0041] The second motor 10 adopts a stepper motor. When the second motor 10 is running, the two rotating shafts 14 are driven to rotate through the transmission belt 9. When the rotating shafts 14 rotate, the movable bracket 8 rotates, thereby achieving the effect of the two vertical ends of the U-shaped spray plate frame 11 being sleeved on the outside of the aluminum ring and moved out of the outside of the aluminum ring. Such a structural setting can facilitate the installation and disassembly of the aluminum ring.

[0042] Embodiment 4:

[0043] This embodiment provides a specific structure of a spray coating device for processing bicycle aluminum rims. Figure 1 As shown, the upper surface of the base frame 3 is provided with a card slot 19 at both sides of the aluminum ring bracket 1. The card slot 19 adopts a slope structure that gradually deepens from the two ends of the base frame 3 to the center. Two plug plates 21 are symmetrically installed at the bottom of the spray bracket 4. The plug plates 21 are inserted into the card slot 19. A flap cover 20 is installed on the upper surface of the card slot 19 through a hinge. The bottom of the flap cover 20 is pressed against the surface of the plug plate 21 and fixed by bolts.

[0044] By adopting the above technical solution:

[0045] The aluminum ring bracket 1 can be disassembled by opening the flap cover 20. Such a structural arrangement allows a component of the device to be repaired or replaced by disassembling the aluminum ring bracket 1 when it is damaged, and also facilitates the transportation of the device.

[0046] Working principle: Refer to Figure 1-4, the two movable brackets 8 are in the initial position, and the initial position is that one end of the two movable brackets 8 is outside the aluminum ring. When the device is in use, first the first motor 2 runs to drive the aluminum ring bracket 1 to rotate, so that the clamping side of the aluminum ring bracket 1 faces outward, and then the center of the aluminum ring is placed on the movable clamp 16 and the fixed clamp 17, and the hydraulic cylinder 15 is opened to move the movable clamp 16, and cooperate with the fixed clamp 17 to clamp and fix the aluminum ring, and then the first motor 2 runs again until the aluminum ring and the spray bracket 4 are in the same plane, and the second motor 10 runs, and drives the movable bracket 8 to rotate through the transmission belt 9 until the U-shaped spray plate frame 11 on the movable bracket 8 is half-wrapped and clamped on the aluminum ring, and finally the third motor 18 runs, and at the same time, the nozzle on the U-shaped spray plate frame 11 starts spraying, achieving the effect of rotary spraying, and completing the operation and use of the device.

[0047] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
