[0002] In the bicycle manufacturing industry, the rim painting process is crucial for improving the product's aesthetics, corrosion resistance, and overall quality.

[0003] Most existing bicycle wheel rim coating equipment is only applicable to rims of specific sizes, lacking versatility and affecting production efficiency.

Regarding coating recycling, existing equipment lacks effective recycling devices, and excess coating generated during the coating process is often directly discharged, which not only wastes the coating and increases production costs but also pollutes the environment.

[0029] The working principle of this utility model is as follows: First, the wheel rim body 5 is clamped. The first motor 22 is started, which drives the first bidirectional lead screw 21 to rotate, causing the two first threaded sleeves 24 to move towards or away from each other. At the same time, the first sliding sleeve 25 on the guide rod 23 moves synchronously with the first threaded sleeves 24 to ensure the stability of the movement. The moving plate 26 at the lower end of the first threaded sleeves 24 and the first sliding sleeves 25 moves accordingly, adjusting the roller 214 to a position that roughly corresponds to the wheel rim body 5 in the horizontal direction. Then, the first electric telescopic rod 27 is started to extend and retract, driving the first mounting plate 28 to move up and down, further adjusting the vertical position of the roller 214 to match the height of the wheel rim. Then, the second motor 210 is started, which drives the second bidirectional lead screw 29 to rotate. The second bidirectional lead screw 29 drives the second threaded sleeves 211 on both sides to move towards each other, thereby causing the roller 214 on the connecting plate 212 to clamp the wheel rim body 5 from both sides. Next, the inner and outer spraying structures are adjusted. The second electric telescopic rod 34 is activated to extend it upwards, raising the inner spray nozzle 37 on the connecting block 35 and the first mounting block 36 to the corresponding spraying position inside the wheel rim body 5. Then, the third electric telescopic rod 39 is activated to raise the second mounting plate 310 to a suitable height, aligning the outer spray nozzle 315 with the outer surface of the wheel rim. The angle of the outer spray nozzle 315 can then be adjusted using the full gear 311, the fourth motor 312, and the partial gear 313. Next, the third motor 213 is activated, driving the roller 214 to rotate. The roller 214 contacts the wheel rim body 5, thereby causing the wheel rim body 5 to rotate. Finally, the spraying mechanism 3 is activated, causing the inner and outer spraying structures to spray the inner and outer surfaces of the wheel rim body 5, respectively. During the spraying process, excess paint flows into the workbench 11 through the through hole 112 on the top surface of the workbench 11. The paint first passes through the filter screen 41, which filters out impurities in the paint. The filtered paint then flows into the recycling bin 42 below, thus realizing the recycling and reuse of the paint.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
