Description

Technical Field

[0001] The utility model relates to the technical field related to wheel rim processing, in particular to a continuous spraying device for processing carbon fiber bicycle wheel rims. Background Art

[0002] A bicycle rim refers to the supporting component of a bicycle tire. The tire is positioned by snapping it into the rim. The rim is driven by a chain and can rotate the tire through the rim, thereby moving the bicycle. It is one of the essential accessories of a bicycle. During the production process of the rim, in order to maintain its aesthetics, the rim is generally painted. Therefore, a continuous spraying device is required to process the rim.

[0003] After searching, the patent with publication number CN214811968U discloses a continuous spraying device for processing carbon fiber bicycle rims;

[0004] By providing a spray box and a spray gun assembly, several groups of spray guns on the spray gun assembly are connected to several groups of liquid storage cavities inside the spray box through pipelines. The same group of coatings can be sprayed to different positions of the carbon fiber bicycle rim by multiple groups of spray guns, and different coatings can also be sprayed continuously. The spraying speed is fast and the spraying efficiency is relatively high. By providing a rotating device and a limiting assembly, when in use, the limiting assembly is installed on the rotating disk, and the carbon fiber bicycle rim is installed on the limiting assembly. The rotating device can change the direction of the rotating disk, thereby adjusting the direction of the carbon fiber bicycle rim. In conjunction with the mechanical arm, the entire carbon fiber bicycle rim can be better sprayed. By providing a driving device and a limiting device, the carbon fiber bicycle rim is installed on the limiting assembly. The limiting assembly can change the height of the carbon fiber bicycle rim so that the carbon fiber bicycle rim contacts the driving wheel. The angle of the carbon fiber bicycle rim is changed by friction, thereby ensuring that the spraying of the carbon fiber bicycle rim has no dead angle, further improving the spraying effect of the carbon fiber bicycle rim. In addition, the continuous spraying device for processing the entire carbon fiber bicycle rim has a simple structure, low cost, good use effect, can be used in large-scale production, and is relatively practical.

[0005] However, this patent still has certain defects in actual use. For example, this patent uses a spray gun assembly to paint the wheel rim, but the spray gun assembly is completely exposed to the air. When the wheel rim is painted, some paint mist will float in the air, which will not only affect the health of the workers, but also fall on the unprocessed wheel rim surface to form paint spots. When spraying these wheel rims with paint spots, these paint spots will affect the overall painting effect of the wheel rim, making the paint spraying on the wheel rim surface uneven, thereby reducing the processing quality of the wheel rim.

[0023] The spraying assembly 5 includes a U-shaped frame 501, the lower surface of which is fixedly connected to a material storage box 502, the front of which is connected to a material feed pipe 503, the inner bottom wall of the U-shaped frame 501 is fixedly connected to a paint pump 504, the output end of the paint pump 504 is connected to a tee 505, the other two ends of the tee 505 are connected to a delivery pipe 506, the front and rear inner walls of the U-shaped frame 501 are provided with circular holes, the inner walls of the circular holes are fixedly connected to a nozzle 507, and the lower surface of the processing table 2 is connected to two return pipes 508.

[0024] Furthermore, the width of the strip plate 303 and the two baffles 304 is the same as the width of the spray tank 4. The strip plate 303 is transported by the transport track 1 and can be stuck on the top of the spray tank 4. At the same time, the two baffles 304 can be stuck on the left and right sides of the spray tank 4, so that a sealed space is formed in the spray tank 4.

[0025] Furthermore, the rear end of the screw 306 is rotatably connected to the inner wall of the chute, and the movable block 307 is threadedly connected to the screw 306.

[0028] Furthermore, the ends of the two return pipes 508 away from the processing table 2 are connected to the interior of the storage box 501. The paint remaining in the spray tank 4 will form a liquid, pass through the surface of the baffle 304 and the inner wall of the spray tank 4, flow downward, and enter the storage box 502 through the return pipe 508, completing the recycling of the paint.

[0029] Furthermore, the auxiliary component 7 includes a positioning frame 701, and the left and right sides of the positioning frame 701 are fixedly connected with mounting plates 702. The lower surfaces of the two mounting plates 702 are threadedly connected with two mounting bolts 703.

The strip plate 303 is stuck in the position above the spray tank 4, and cooperates with the two baffles 304 to seal the spray tank 4. When spraying paint, the fan 704 can blow air downward and blow the paint mist to the bottom of the spray tank 4. At this time, the paint mist forms a liquid state and flows back into the storage box 502 through the return pipe 508, ensuring that the paint mist will not float in the air and affect the unprocessed painted rims, while also reducing the impact of the paint mist on the staff.

[0030] Working principle: First, clamp the wheel rim on the circular shaft 311 and contact the clamping ring 312. At this time, rotate the screw 306 to make the movable block 307 drive the top plate 308 to move successively, so that the top plate 308 drives the rubber sleeve 309 to clamp into the surface of the circular shaft 311, and at the same time, tighten the wheel rim. The transmission track 1 drives the strip plate 303 to move to the position of the processing table 2 through the slider 301 and the connecting rod 302. The two baffles 304 can be clamped on the inner wall of the spray tank 4. At the same time, the strip plate 303 is clamped on the top of the spray tank 4. At this time, the servo motor 310 starts and drives the circular shaft 311 to rotate. Since the rubber sleeve 309 can press the wheel rim against the circular shaft 311, the wheel rim can follow the circular shaft 311. 11 rotates, at this time the paint pump 504 transports the paint in the storage box 502 to the nozzle 507 through the tee 505 and the two delivery pipes 506, and then sprays it onto the wheel rim surface through the nozzle 507 to realize the painting processing operation of the wheel rim. At the same time, during the painting process, the paint forms paint mist in the spray tank 4. At this time, the fan 704 is started, which can blow the paint mist in the spray tank 4 downward, so that the paint mist forms a liquid in the spray tank 4, and at the same time flows back into the storage box 502 through the two return pipes 508, and will not float in the air and adhere to the unpainted wheel rim surface, thereby greatly improving the spraying quality of the wheel rim, while also improving the protection of the staff in the workshop and reducing paint waste.
