The three paint spray devices 41 are respectively arranged on the top of the first supporting frame 1 and on the front and rear outer walls of the first supporting frame 1. The paint spray device 41 adopts an existing device and will not be repeated here. The paint spray device 41 on the top of the first supporting frame 1 is connected with a nozzle group 1 42, and the nozzle group 1 42 corresponds to the first component 3111, the second component 3112 and the third component 3113. The paint spray devices 41 on the front and rear sides of the second supporting frame 2 are connected with a nozzle group 2 43 and a nozzle group 3 44. The two nozzle groups 2 43 are arranged correspondingly, and the two nozzle groups 3 44 are also arranged correspondingly. At the same time, the nozzle group 2 43 corresponds to the part of the first component 3111 located inside the first supporting frame 1, and the nozzle group 3 44 corresponds to the third component 3113.

[0059] The first air-drying component 5 includes two U-shaped air ducts 51 and a first air duct 52. The two U-shaped air ducts 51 are respectively arranged on the outer walls of the front and rear sides of the first supporting frame 1. The two U-shaped air ducts 51 are symmetrically arranged, and the U-shaped air ducts 51 correspond to the fourth component 3114; one end of each U-shaped air duct 51 is closed and the other end is connected to the first air inlet 53, and one end of the first air duct 52 is closed and the other end is also connected to the first air inlet 53. The first air inlet 53 is used to connect to an external hot air source, so as to introduce gas into the U-shaped air duct 51, and the first air inlet 53 is provided with a An electromagnetic control valve is provided; a plurality of first air nozzles 54 are connected to each U-shaped air duct 51, and the plurality of first air nozzles 54 on the U-shaped air duct 51 are arranged at intervals along the length direction of the U-shaped air duct 51; the first air duct 52 is arranged at the top of the first support frame 1, and a plurality of first air nozzles 54 are also provided on the first air duct 52, and the plurality of first air nozzles 54 on the first air duct 52 are arranged at intervals along the length direction of the first air duct 52; in addition, each first air nozzle 54 penetrates the first support frame 1, and each first air nozzle 54 is used to spray hot air flow into the first support frame 1.

At this time, the two ends of the wheel hub are not painted. In the process of the wheel hub passing through the second component 3112, the wheel hub rolls, which is conducive to the natural drying of the paint on the surface of the wheel hub, making it easier for the paint to adhere to the wheel hub, while the circumference of the wheel hub continues to be painted to ensure that the contact parts of the arc protrusion 1 32 and the arc protrusion 2 33 with the wheel hub can adhere to the paint; when the wheel hub passes through the third component 3113, the second paint nozzle 431 included in the nozzle group 3 44 sprays paint on the two ends of the wheel hub again, and the first paint nozzle 421 corresponding to the third component 3113 continues to spray paint on the circumference of the wheel hub to ensure that all parts of the wheel hub are sprayed, thereby improving the painting effect.

[0061] When the wheel hub passes through the fourth component 3114, a hot air flow is sprayed through the multiple first air nozzles 54 to accelerate the drying of the paint liquid; finally, the wheel rolls through the arc transition section 312 and rolls upward along the inclined section 2 313 for a distance, and then rolls downward again. Relying on the action of gravity, the wheel hub can roll back and forth between the inclined section 2 313 and the inclined section 1 311, so that the wheel hub stops on the arc transition section 312, and the painted wheel hub can be taken out through the material taking port 21.

[0062] In this embodiment, the wheel hub is rolled along the guide plate assembly 3 by the cooperation with the wheel hub, so that the wheel hub is sprayed and dried. In this process, there is no need to use other power mechanisms to drive the wheel hub to operate, which improves the convenience of the spraying operation; during the rolling process of the wheel hub, it helps to accelerate the drying of the paint liquid; in addition, cooperating with the spray assembly 4 can also facilitate improving the spraying effect.
