[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The double-sided spraying equipment for automobile wheel hubs involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] This utility model provides a double-sided spraying equipment for automobile wheel hubs, such as... Figure 1 - Figure 4 As shown, the device includes an operation box 1 and two doors 2 fixedly connected to one end of the operation box 1. Two hinges 3 are provided at the connection between the operation box 1 and the doors 2. A torsion spring 4 is provided in the middle of the hinge 3. A base plate 5 is fixedly connected to the bottom of the operation box 1. A support assembly 6 for placing the wheel hub is provided at the top of the base plate 5. A drying box 12 is fixedly installed at the top of the operation box 1. Two drying fans 13 are fixedly installed at the bottom of the drying box 12. After the wheel hub is painted, it is directly dried by the drying fans 13 to avoid accidental contact during movement, which would damage the painted surface.

[0022] Furthermore, such as Figure 2 and Figure 3 As shown, the support assembly 6 includes a support plate 61 located at the top of the base plate 5. A support frame 62 is fixedly installed at the top of the support plate 61. Slider 63 is fixedly connected to both ends of the support plate 61. A storage tray 64 is fixedly connected to the top of the support frame 62. The wheel hub to be painted is placed on the top of the storage tray 64, and the support frame 62 provides support.

[0023] Furthermore, such as Figure 2 and Figure 3 As shown, a groove is provided in the middle of the bottom of the operation box 1. Guide rails 7 are fixedly connected to both sides of the inner wall of the groove. The support plate 61 is located in the inner cavity of the groove, and the slider 63 is movably connected to the guide rails 7.

[0024] Furthermore, such as Figure 4As shown, a motor 65 is fixedly installed at the bottom of the support plate 61, and a cylinder 66 is fixedly installed at the other end of the control box 1. The output end of the motor 65 passes through the support plate 61 and is fixedly connected to the bottom end of the support frame 62. During the spraying process, the motor 65 is started, which causes the support frame 62 to rotate, driving the hub to rotate at a uniform speed, ensuring that the surface of the hub can be sprayed evenly. The extended end of the cylinder 66 passes through the control box 1 and is fixedly connected to one end of the support plate 61. The cylinder 66 pushes the support plate 61 to move. During the movement of the support plate 61, the slider 63 slides on the surface of the guide rail 7, ensuring the stability of the movement of the support plate 61. At the same time, the push of the support plate 61 causes the box door 2 to open. After the hub on the support assembly 6 is removed, the cylinder 66 retracts, causing the support plate 61 to return to its original position. The box door 2 then automatically rebounds and closes through the torsion spring 4 in the middle of the hinge 3, effectively reducing manual intervention and contact, and preventing the spray generated during the spraying process from spreading everywhere.

[0025] Furthermore, such as Figure 1 As shown, an exhaust fan 8 is fixedly installed on one side of the inner cavity of the control box 1. The output end of the exhaust fan 8 is fixedly connected to an exhaust pipe 9. Since a large amount of spray will be generated during the spraying process, it will be centrally discharged and treated through the exhaust fan 8 and the exhaust pipe 9.

[0026] Furthermore, such as Figure 1 and Figure 2 As shown, two spray guns 10 are fixedly installed on the other side of the inner cavity of the control box 1. The input end of the spray gun 10 is fixedly connected to the connecting pipe 11, which is connected to the output end of the external paint storage device. The installation height of one of the spray guns 10 is adapted to the height of the tray 64, and the other spray gun 10 is set to tilt. When the motor 65 drives the hub to rotate at a constant speed, one spray gun 10 sprays the side of the hub, and the tilted spray gun 10 sprays the top surface of the hub, thus completing the double-sided spraying operation at the same time, which effectively improves the spraying efficiency.

[0027] Furthermore, such as Figure 2 and Figure 3 As shown, a baffle 14 is provided above the guide rail 7, and the baffle 14 is fixedly connected to the inner cavity of the operation box 1.

[0028] The working principle of this utility model is as follows: First, the cylinder 66 is activated, and its extended end extends to its maximum length, pushing the support plate 61 to move. The support plate 61 then causes the door 2 to rotate and open. Next, the wheel hub to be sprayed is placed on top of the tray 64. After placement, the cylinder 66 is activated again, causing its extended end to retract to its shortest length. As the cylinder 66 moves the support plate 61, the slider 63 slides on the surface of the guide rail 7, ensuring the stability of the support plate 61's movement. When the support plate 61 moves into the operating box 1, the door 2 automatically closes via the torsion spring 4 in the middle of the hinge 3, preventing the spray generated during spraying from scattering. Before spraying, the connecting pipe 11 is connected to the external paint storage device. At the outlet, spraying is performed using spray guns 10. One spray gun 10 sprays the side of the wheel hub, while the tilted spray gun 10 sprays the top surface of the wheel hub, completing the double-sided spraying operation simultaneously, effectively improving spraying efficiency. During the spraying process, motor 65 is started, which drives the wheel hub to rotate at a constant speed to ensure the uniformity of the spraying. The large amount of spray generated during the spraying process is centrally discharged through exhaust fan 8 and exhaust pipe 9. After the wheel hub is sprayed, it is directly dried by drying fan 13 to avoid accidental contact during movement, which could damage the sprayed surface. After drying, cylinder 66 is started again to push support plate 61, moving the wheel hub out of the operation box 1, effectively reducing manual intervention and contact.

[0029] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
