[0027] Example

[0028] Please refer to Figure 1 This embodiment provides a powder blowing device for the center hole of a wheel, including a powder blowing pipe 1, a lifting motor 2, a compressed air pipe 3, a powder extraction pipe 4, and a powder extraction fan 5. A powder blowing hole 110 is formed on the side wall of the powder blowing pipe 1. The powder blowing pipe 1 is installed in the center hole 101 of the wheel 100, and air is blown through the powder blowing hole 110 to blow powder into the center hole 101 of the wheel 100 after powder spraying. The lifting motor 2 is connected to the powder blowing pipe 1 and is used to drive the powder blowing pipe 1 to move up and down. The compressed air pipe 3 is connected to the powder blowing pipe 1 and is used to provide compressed air to the powder blowing pipe 1 for powder blowing.

The powder extraction fan 5 is located at the outlet of the powder extraction pipe 4 and is used to provide a suction power source to the powder extraction pipe 4.

[0029] In this embodiment, the wheel center hole powder blowing device is used with the wheel 100 positioned at the powder blowing station. The powder blowing pipe 1 is installed inside the center hole 101 of the wheel 100. Both ends of the compressed air pipe 3 are connected to a compressed air source and the powder blowing pipe 1, respectively. Compressed air is supplied to the powder blowing pipe 1 through the compressed air pipe 3 and ejected through the powder blowing hole 110, thus blowing powder into the center hole 101 of the wheel 100 after powder spraying. The powder blowing pipe 1 can be moved up and down by the lifting motor 2, allowing for adjustment of the powder blowing height according to actual needs, making it suitable for wheels 100 of different heights and ensuring powder blowing effect and efficiency. The powder extraction fan 5 provides suction power to the powder extraction pipe 4, enabling the powder extraction pipe 4 to extract the powder blown from the powder blowing pipe 1, preventing secondary contamination of the center hole 101 of the wheel 100 by the powder.

[0030] Please refer to Figure 2 Specifically, the powder blowing device for the center hole of the wheel also includes a camera recognition component 6, which includes a camera, a memory, and a processor. The processor is connected to the camera and the memory respectively. The camera is used to capture images of the wheel 100 and send them to the processor. The memory is used to store the wheel type database. The processor is used to analyze and process the images, obtain the diameter and height data of the wheel 100, and compare the data with the data in the wheel type database to obtain the model of the wheel 100.

[0031] In this embodiment of the wheel center hole powder blowing device, an identification station is set up in front of the powder blowing station of the wheel 100, and the camera identification component 6 is set at the identification station. When the wheel 100 is located at the identification station, the camera captures an image of the wheel 100 and sends the image to the processor; the processor compares the image with the data in the wheel type database stored in the memory to obtain the model of the wheel 100. The camera identification component 6 can be a product of existing technology for identifying the wheel type of the wheel 100.

[0032] Figure 2 The hollow arrow indicates the direction of travel of wheel 100. Figure 2 The right side represents the front, and the left side represents the rear.

[0033] Specifically, there are at least two powder blowing holes 110, and the multiple powder blowing holes 110 are evenly distributed along the circumference of the powder blowing tube 1.

[0034] The multiple powder blowing holes 110 distributed circumferentially help to ensure the powder blowing effect and efficiency.

[0035] Specifically, the powder blowing holes 110 are arranged in at least four rows along the length of the powder blowing tube 1, and the multiple rows of powder blowing holes 110 are evenly distributed along the length of the powder blowing tube 1.

[0036] By using multiple rows of powder blowing holes 110 distributed along the length of the powder blowing pipe 1, the height of the powder blowing holes 110 can be easily adjusted, better meeting the different height requirements of the center hole 101 of different wheels 100.

[0037] Specifically, the powder blowing hole 110 is located on the top side wall of the powder blowing tube 1.

[0038] The powder blowing hole 110 provided at the top of the powder blowing pipe 1 facilitates the blowing of powder into the center hole 101 of the wheel 100.

[0039] Specifically, the power output end of the lifting motor 2 is set as a ring structure, which is sleeved on the outside of the powder blowing pipe 1; a connecting hose 7 is sleeved on the outside of the powder blowing pipe 1, and the connecting hose 7 is connected to the ring structure and the outer wall of the powder blowing pipe 1 respectively.

[0040] The annular structure can be fixedly connected to the powder blowing pipe 1. Alternatively, the annular structure can be movably sleeved on the outside of the powder blowing pipe 1 and connected to the annular structure of the lifting motor 2 and the powder blowing pipe 1 respectively through the connecting hose 7. This can achieve a flexible connection between the lifting motor 2 and the powder blowing pipe 1, which helps to avoid stress concentration at the connection between the lifting motor 2 and the powder blowing pipe 1, improves the stability of the connection, and prevents breakage.

[0041] Specifically, the bottom end of the powder blowing pipe 1 is connected to the top end of the compressed air pipe 3.

[0042] The top end of the compressed air pipe 3 is connected to the bottom end of the powder blowing pipe 1, which facilitates the connection between the compressed air pipe 3 and the powder blowing pipe 1, and facilitates the supply of compressed air to the powder blowing hole 110 of the powder blowing pipe 1 through the compressed air pipe 3 for powder blowing.

[0043] Specifically, the top of the powder extraction tube 4 is set as the inlet, and the bottom is set as the outlet; the inlet is located below the powder blowing hole 110.

[0044] The powder extraction tube 4, through an inlet located below the powder blowing hole 110, facilitates the intake of powder through the top inlet and the discharge of powder through the bottom outlet.

[0045] Specifically, the inlet is designed as an inverted tapered tube.

[0046] The inverted conical inlet of the powder extraction tube 4 facilitates the collection of powder blown off by the powder blowing hole 110, preventing powder from splashing out.

[0047] Specifically, the powder blowing pipe 1 and the powder extraction pipe 4 are arranged coaxially.

[0048] The powder blowing tube 1 is coaxially sleeved inside the powder extraction tube 4, which facilitates the powder extraction tube 4 to collect the powder blown off by the powder blowing hole 110, thus preventing powder leakage.

[0049] Please refer to the reference. Figure 1 and Figure 2 The powder blowing device for the wheel center hole in the above embodiment can also specifically be configured such that the wheel 100 is an aluminum alloy wheel, i.e., a wheel hub. The center hole 101 is a circular through hole at the center of the wheel 100.

[0050] The powder blowing pipe 1 is a vertical circular pipe. In use, the powder blowing pipe 1 is installed inside the central hole 101, and the top end of the powder blowing pipe 1 is located below the top end of the central hole 101. The diameter of the powder blowing pipe 1 is less than or equal to φ32mm.

[0051] The powder blowing hole 110 is a square hole. The powder blowing hole 110 is located on the top side wall of the powder blowing tube 1. That is, the powder blowing hole 110 is also located inside the central hole 101, and its height is lower than the top height of the central hole 101.

[0052] The lifting motor 2 is located below the wheel 100, and the annular structure is a circular ring that is movably fitted around the outside of the powder blowing pipe 1.

[0053] The connecting hose 7 is configured as a retractable hose; for example, the connecting hose 7 is configured as a corrugated hose.

[0054] The connecting hose 7 is sleeved on the outside of the powder blowing pipe 1. The two ends of the connecting hose are connected to the annular structure and the powder blowing pipe 1, respectively. For example, the connecting hose 7 is located below the annular structure, with the top end of the connecting hose 7 connected to the bottom end of the annular structure and the bottom end connected to the outer wall of the powder blowing pipe 1.

[0055] The compressed air pipe 3 is configured as a circular pipe, for example, it can be configured as a corrugated pipe. The top end of the compressed air pipe 3 is connected to the bottom end of the powder blowing pipe 1, and the bottom end is connected to the compressed air source.

[0056] The powder extraction tube 4 is a circular tube. The inlet of the powder extraction tube 4 is an inverted conical tube.

[0057] The powder blowing station is located behind the identification station. After the model of the wheel 100 is identified by the identification station, it arrives at the powder blowing station for powder blowing.

[0058] The camera is set to a 2D camera. The camera is mounted on a bracket, which is set at the recognition station.

[0059] The processor is connected to the controller, and the controller is connected to the lifting motor 2. Based on the model of the wheel 100, the processor obtains the direction and distance information of the lifting direction and movement of the powder blowing hole 110 on the powder blowing pipe 1 driven by the lifting motor 2, and sends this information to the controller. The controller then controls the lifting motor 2 to drive the powder blowing pipe 1 and the powder blowing hole 110 to move vertically and horizontally based on this information.

[0060] The wheel center hole powder blowing device of the above embodiment is designed to perform a base powder coating and a top transparent powder coating operation on the wheel 100. By opening a powder blowing hole 110 on the powder blowing pipe 1, powder is blown into the center hole 110 of the powder-coated aluminum alloy wheel. The airflow mixed with powder is drawn away through the powder extraction pipe 4 to avoid secondary pollution.

[0061] Due to the height difference of different wheels 100, the powder blowing hole 110 is driven by the lifting motor 2 to move the powder blowing pipe 1 up and down, which is beneficial for powder blowing operations applicable to various wheels 100.

[0062] To facilitate switching between products with different wheels 100 on-site, a camera recognition component 6 is installed to scan and identify wheel types before powder blowing onto the wheels 100. The corresponding height values ​​for each wheel type 100 are pre-set and stored in the wheel type database. After the camera captures an image of the wheel 100, the processor calls a program to analyze and process the image, confirm the wheel type parameters, and then controls the lifting motor 2 to move the powder blowing pipe 1 and the powder blowing hole 110 up and down, adjusting the height of the powder blowing hole 110 to match the height of the wheel type 100, thus enabling powder to be blown from the center hole 101 of different wheels 100.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
