[0037] The control cabinet is fixed on the base 7; the first motor 2, the second motor 101, the third motor, the sandblasting unit are electrically connected to the control cabinet.

[0038] Installation and Preparation:

[0039] Equipment Arrangement: Place the base 7 steadily at the designated ground position to ensure that the base 7 is stable and does not shake. Subsequently, install components such as the processing chamber 3, the sandblasting unit, the polishing unit 8, the rotating unit 10, and the control cabinet onto the base 7 one by one according to the design drawings, and tighten all connecting parts to ensure the connection between components is firm and reliable.

[0040] Power Supply Connection: Connect the main power cable of the processing device to the power interface of the control cabinet, and check whether the power voltage meets the equipment requirements. At the same time, supply power to each motor and control component in the control cabinet to ensure that the equipment can start and operate normally.

[0041] Debugging and Inspection: Before formally processing the wheels, conduct a comprehensive debugging and inspection of the equipment. This includes checking whether components such as the sandblasting gun, the polishing block 83, and the motors are operating normally, adjusting parameters such as the sandblasting volume and polishing intensity to the appropriate range, and confirming whether the various functions of the control cabinet are in good condition.

[0042] Wheel Installation and Fixation:

[0043] Wheel Positioning: Place the aluminum alloy wheel to be processed on the positioning shaft rod 105 of the rotating unit 10 to ensure that the center of the wheel is aligned with the center of the positioning shaft rod 105. By rotating the pressing head 104 on the positioning shaft rod 105, make the pressing head 104 closely contact the rim or spoke of the wheel, and use the cooperation of the threaded column and the threaded groove to firmly fix the wheel on the positioning shaft rod 105.

[0044] Angle Adjustment: According to the shape of the wheel and the parts to be processed, start the second motor 101 through the control cabinet to drive the bent rod 103 and the support seat 106 to rotate, thereby adjusting the angle of the wheel relative to the sandblasting gun and the polishing block 83. Ensure that all parts of the wheel can be evenly processed.

[0045] Sandblasting Processing Stage:

[0046] Start the Sandblasting Unit: After confirming that the wheel is firmly fixed and the angle is adjusted, start the sandblasting unit through the control cabinet. The abrasive in the sandblasting hopper 1 is ejected through the sandblasting gun under the action of air pressure to conduct sandblasting on the wheel surface.

[0048] Polishing process stage:

[0049] Lower the polishing block 83: After the sandblasting process is completed, start the first motor 2 through the control cabinet to drive the screw rod 85 to rotate. The rotation of the screw rod 85 causes the slider 84 to descend along its threaded track until the polishing block 83 contacts the wheel surface. At this time, start the motor or pneumatic device on the polishing block 83 to polish the wheel surface with the polishing block 83.

[0050] Multi-angle polishing: To ensure that all parts of the wheel can be evenly polished, repeatedly adjust the angle and position of the wheel. By controlling the coordinated operation of the second motor 101 and the third motor, the wheel rotates at different angles and positions while keeping the contact and polishing force of the polishing block 83 unchanged. In this way, the polishing block 83 can comprehensively polish all parts of the wheel.

[0051] In this embodiment, a discharge port is provided at the bottom of the processing chamber 3; a discharge bin 5 is installed on the discharge port; a vertical partition 13 is fixedly arranged inside the discharge bin 5 to divide the interior of the discharge bin 5 into a left discharge channel 12 and a right discharge channel 14; the bottom of the left discharge channel 12 is connected to a left discharge hopper 6; the bottom of the right discharge channel 14 is connected to a right discharge hopper 4; an adjustment hole is provided on the vertical partition 13; a gate plate 11 is installed in the adjustment hole; a pin shaft is fixedly arranged at the bottom of the gate plate 11; the gate plate 11 is hinged to the discharge bin 5 through the pin shaft; a fourth motor 15 is fixedly arranged outside the discharge bin 5, and the output shaft of the fourth motor 15 is connected to the pin shaft.

[0052] Cleaning and discharging:

[0053] Clean the processing chamber 3: After completing the surface treatment of all wheels, turn off all motors and the sandblasting unit. Use a vacuum cleaner or a high-pressure air gun to clean the sand residue and dust impurities inside the processing chamber 3 to keep the interior of the equipment clean and hygienic.

[0054] Discharging operation: Open the gate plate 11 on the discharge port to make the processed wheels slide out of the discharge bin 5. According to the flow direction and quantity requirements of the waste, it is possible to choose to discharge from the left discharge channel 12 or the right discharge channel 14 and control the discharge speed and flow rate by adjusting the position of the gate plate 11. Finally, collect the processed wheels for subsequent assembly or use.

[0055] In this embodiment, the polishing unit 8 further includes a first protective cover 81; the first protective cover 81 is fixedly connected to the processing chamber 3; the first protective cover 81 is buckled outside the screw rod 85; a chute 82 adapted to the slider 84 is provided on the first protective cover 81; the length direction of the chute 82 is parallel to the axis direction of the screw rod 85; the screw rod 85 is protected by the first protective cover 81.

[0056] In this embodiment, the rotating unit 10 further includes a second protective cover 107; the second protective cover 107 is fixed on the support base 106, and the third motor is arranged inside the second protective cover 107; the third motor is protected by the second protective cover 107.

[0057] In this embodiment, the diameter of the positioning shaft rod 105 gradually decreases from the end close to the third motor to the other end, which is adapted to fix wheels of different models.

[0058] In this embodiment, a threaded post is fixedly arranged on the pressing head 104; a threaded groove adapted to the threaded post is provided on the positioning shaft rod 105, and the threaded post is detachably installed in the threaded groove.

[0059] The working principle is as follows:

[0060] Installing and fixing the wheel: First, install the aluminum alloy wheel to be processed on the positioning shaft rod 105 of the rotating unit 10. By rotating the pressing head 104 on the positioning shaft rod 105, the wheel is firmly fixed on the positioning shaft rod 105.

[0061] Sandblasting treatment: Start the sandblasting unit, and the sandblasting gun will spray sand from the sandblasting material bin 1 to perform sandblasting treatment on the surface of the wheel. The purpose of sandblasting is to remove the oxide layer and dirt on the surface of the wheel, and at the same time increase the surface roughness to prepare for the subsequent polishing treatment. The sandblasting gun is fixed inside the processing chamber 3 and above the horizontal partition net 9, so that the sandblasting can evenly cover the surface of the wheel.

[0062] Angle adjustment: During the sandblasting process, start the second motor 101 through the control cabinet to drive the bent rod 103 to rotate, thereby changing the angle of the wheel relative to the sandblasting gun. In this way, the sandblasting gun can evenly sandblast each angle of the wheel to ensure that the entire surface of the wheel is fully processed.

[0063] Wheel rotation: Start the third motor to drive the positioning shaft rod 105 to rotate. When the positioning shaft rod 105 rotates, the wheel fixed on it also rotates accordingly. The speed and direction of the wheel rotation can be controlled through the control cabinet to ensure the uniformity of sandblasting and polishing.

[0064] Polishing treatment: After the sandblasting treatment is completed, start the first motor 2 to drive the screw 85 to rotate. When the screw 85 rotates, the slider 84 moves along the thread track of the screw 85. A polishing block 83 is fixed on the slider 84. When the slider 84 descends to the appropriate position, the polishing block 83 will be located on one side of the wheel. At this time, start the polishing block 83 to polish the wheel. The purpose of polishing is to further flatten the surface of the wheel to make it smooth and bright.

[0065] Multi-angle polishing: To ensure that all parts of the wheel can be evenly polished, by controlling the coordinated operation of the second motor 101 and the third motor, the wheel rotates at different angles and positions. In this way, the polishing block 83 can comprehensively polish all parts of the wheel to ensure that the final surface treatment effect is uniform and of high quality.

[0066] Control and monitoring: The entire surface treatment process is uniformly managed by the control cabinet. The control cabinet controls the start and stop of the first motor 2, the second motor 101, the third motor and the sandblasting unit respectively through electrical connections. The operator can monitor and adjust the working status of each unit in real time through the control cabinet to ensure the accuracy and efficiency of the wheel surface treatment.
