Description

Technical Field

[0001] This utility model relates to the field of wheel hub spraying technology, specifically a wheel hub surface coating spraying device. Background Technology

[0002] Wheel hub surface coating spraying equipment is specifically designed for spraying coatings (such as anti-rust coatings, decorative coatings, etc.) onto the surface of wheel hubs. It is commonly used in the manufacturing and repair of wheel hubs in the automotive, motorcycle, and bicycle industries, providing improved aesthetics, durability, and corrosion resistance. Spraying equipment typically consists of a main body, a paint supply system, and an air compression system. The main body usually comprises a spray gun, spray nozzles, and a spray chamber, responsible for spraying and applying the paint. The paint supply system delivers the paint from the storage container to the spray gun and controls the paint flow and pressure to ensure optimal spraying results. A stable air compression system is required to drive the atomization process of the spray gun.

[0003] Most spraying nozzles are atomizing nozzles, and the nozzle design determines the spray width, atomization effect, and spray volume. Different coatings require different nozzle sizes to control the uniformity of the coating. Automated spraying equipment is mostly installed above a conveyor, which transports rotating hubs. Starting the spraying equipment allows for spraying the upper part of the hub. However, due to the different designs of each hub, especially the spokes, various spoke shapes can easily lead to spraying dead zones. To increase the spraying area and reduce spraying dead zones, a hub surface coating spraying device is provided. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wheel hub surface coating spraying device, comprising a top cover and a turntable;

[0006] The turntable is rotatably connected to the lower end of the top cover. The lower end of the turntable is connected to a nozzle, which is set at an angle. The top cover is installed above the conveyor via a truss. The upper end of the top cover is connected to a pump, and a motor for driving the turntable to rotate is installed at the upper end of the top cover.

[0007] As a preferred technical solution of this utility model, the top cover includes two spliced ​​shells.

[0008] As a preferred technical solution of this utility model, a side strip is fixedly connected to the upper end of the splicing point of the two shells, and the side strips of the two shells fit together.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention uses a motor to drive a turntable to rotate, which in turn drives the spray head to rotate synchronously. The pump is started, and the paint enters the spray head through the top cover and the turntable. The atomized paint is then sprayed onto the surface of the wheel hub through the spray head. The spray head can be tilted towards the wheel hub to increase the spraying angle, thereby reducing spraying dead angles. This solves the problem of multiple spraying dead angles that are easy to occur in existing wheel hub spraying equipment. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This embodiment provides a wheel hub surface coating spraying device, including a top cover 1, such as... Figure 1 As shown, the top cover 1 is mounted above the conveyor via a truss. Multiple hubs are rotatably mounted on the conveyor, which is equipped with a motor to drive the hubs. This allows the hubs below the top cover 1 to rotate at a stable speed during spraying, facilitating even coating of the paint onto their surfaces. The top cover 1 consists of two semi-circular shells joined together, with grooves formed at the joint surface. Adhesive strips are installed within these grooves to seal the two shells, preventing paint leakage during spraying and ensuring that paint is only sprayed onto the hub surface through the nozzles 3, reducing paint waste and contamination.

[0025] like Figure 1 and Figure 5 As shown, two side strips 11 are fixedly connected to the upper end of the shell splice. The two shell side strips 11 fit together, and a cover 12 is engaged on the outer wall of the two fitting side strips 11, making the two side strips 11 fit tightly together. The cover 12 and the two side strips 11 are connected by multiple screws, thereby effectively limiting the joint area, ensuring the connection stability of the top cover 1, and further improving the durability of the equipment.

[0026] like Figure 1 and Figure 2 As shown, the upper end of the top cover 1 is connected to multiple connecting frames 13 by screws. The connecting frames 13 are then connected to the truss by screws. The multiple connecting frames 13 connect the spraying device to the truss while stabilizing the entire spraying device.

[0027] like Figure 2 and Figure 4 As shown, a turntable 2 is rotatably mounted on the lower end of the top cover 1, and a motor is fixedly mounted on the upper end of the top cover 1 via a bracket. The output shaft of the motor is inserted into the top cover 1, and one end of the output shaft is fixedly connected to the upper end of the turntable 2. By starting the motor, the turntable 2 is driven to rotate at the lower end of the top cover 1. A sealed rotating shaft is installed at the connection between the motor output shaft and the top cover 1. The sealed rotating shaft ensures a sealed connection between the motor output shaft and the top cover 1 while also ensuring the rotation of the motor output shaft.

[0028] A pump is connected to the upper end of the top cover 1 via a pipeline. The pump includes a paint supply system and an air compression system. Starting the pump will deliver the paint through the pipeline into the top cover 1. Figure 3 and Figure 4 As shown, a drain port is provided at the lower edge of the turntable 2, and a nozzle 3 is connected to the drain port at the lower end of the turntable 2 via a corrugated pipe 31. A mounting bracket 32 ​​is fixedly connected to the lower end of the turntable 2. The nozzle 3 is rotatably connected to the mounting bracket 32 ​​by a screw. The rotation angle of the nozzle 3 can be fixed by tightening the screw. The corrugated pipe 31 extends and retracts as the nozzle 3 rotates. The nozzle 3 is an atomizing nozzle; after the paint is discharged from the nozzle 3 through the drain port, it can spray out an umbrella-shaped atomized liquid.

[0029] The conveyor for transporting wheel hubs is equipped with multiple rotating frames, with the wheel hubs fixedly connected to the upper ends of the rotating frames. When the spraying device is in use, the conveyor is controlled to move a rotating frame without a wheel hub directly below the top cover 1. Then, the nozzle 3 is adjusted so that it is tilted and aligned with the rotating frame below. After the motor on the conveyor is started, the rotating frame drives the wheel hub to rotate. The motor on the upper end of the top cover 1 is controlled to make the turntable 2 rotate in the opposite direction to the rotating frame. The pump and conveyor are started, and while the conveyor transports the wheel hub, the spraying device performs the spraying. The tilted and rotating nozzle 3 increases the spraying angle of the wheel hub, further expanding the sprayed area while reducing spraying dead zones.

[0030] After spraying, to prevent paint buildup inside the top cover 1, such as... Figure 6 As shown, the upper end of the turntable 2 has an inclined surface that slopes towards the drain outlet. The liquid accumulated on the turntable 2 will slide on the turntable 2 by its own gravity to the drain outlet and be completely discharged.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
