Color separation and masking device for multi-color gradient spraying of aluminum alloy wheel hub

Abstract

This utility model discloses a color separation and masking device for multi-color gradient spraying of aluminum alloy wheel hubs, including a support frame. Inside the support frame, a color separation and masking mold plate, a second housing, and a first housing are sequentially installed. In use, starting a stepper motor, in conjunction with the transmission action of a worm gear and worm wheel, drives the air guide pipe and the wheel hub fixing rod to rotate. This causes the aluminum alloy wheel hub product, which is adsorbed and fixed on the wheel hub fixing rod, to rotate accordingly. Furthermore, with the real-time position feedback of the stepper motor shaft from the encoder, the stepper motor can achieve quantized angle drive through pulses. This allows the user to pre-input the rotation angle of the stepper motor to the PLC controller, enabling the drive mechanism to drive the aluminum alloy wheel hub product to rotate at precise angles, ensuring that the color separation areas sequentially align with the spraying nozzles, thereby improving color separation accuracy and efficiency.

[0002] Aluminum alloy wheels are widely used in automobiles and motorcycles due to their beautiful appearance, lightweight and high strength. In order to meet different appearance requirements, aluminum alloy wheels often need to be treated with multi-color gradient spraying. In order to improve the spraying quality during the multi-color gradient spraying process, color separation and masking devices are required.

[0003] Existing color separation and masking devices for multi-color gradient spraying of aluminum alloy wheels require manual operation using tools such as tape and paper. These manual color separation and masking structures are cumbersome, inefficient, time-consuming, and labor-intensive. Based on this, we propose a new type of color separation and masking device for multi-color gradient spraying of aluminum alloy wheels. Utility Model Content

[0007] Preferably, the bottom of the color separation masking mold plate is provided with fixing posts on both sides that engage with the support frame, and the support frame is provided with fixing slots that engage with the fixing posts.

[0008] Preferably, bearings are provided between the worm and the worm wheel and the inner wall of the second housing.

[0009] Preferably, a rubber limiting ring is fitted onto the fixing rod for the wheel hub.

[0010] Preferably, the air duct extends laterally through both ends of the second housing.

[0012] Preferably, the material of the color separation masking mold plate is polypropylene plastic, which makes the color separation masking mold plate low in cost and easy to clean the paint adhering to it.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The multi-color gradient spraying device for aluminum alloy wheel hubs is equipped with a stepper motor, which optimizes the device’s performance. When the stepper motor is started, the transmission action of the worm and worm wheel can drive the air pipe and the fixed rod for the wheel hub to rotate. This can drive the aluminum alloy wheel hub product that is adsorbed and fixed on the fixed rod for the wheel hub to rotate. With the real-time position feedback of the stepper motor shaft by the encoder, the stepper motor can achieve quantitative driving of the angle through pulses. This makes it easy for the user to input the rotation angle of the stepper motor to the PLC controller in advance, so that the drive mechanism can drive the aluminum alloy wheel hub product to rotate at a precise angle, so that the color separation area on it faces the spraying port in sequence. This facilitates the automated color separation spraying of different color areas of the aluminum alloy wheel hub product, improving the color separation accuracy and efficiency. In addition, the self-locking effect of the worm wheel relative to the worm also ensures the smooth performance when the stepper motor drives the fixed rod for the wheel hub with the product to rotate.

[0015] (2) The multi-color gradient spraying device for aluminum alloy wheels optimizes its structure by installing a wheel hub fixing rod, etc. On the one hand, the user selects a wheel hub fixing rod with a corresponding diameter according to the size of the middle opening of the aluminum alloy wheel product and threads it to the front end of the air guide pipe. In actual operation, the wheel hub fixing rod is inserted into the middle hole of the aluminum alloy wheel product, and then the air pump is started to extract the gas inside the wheel hub fixing rod through the Y-shaped connecting pipe and the air guide pipe, so that the rubber suction cups on the surface of the wheel hub fixing rod are subjected to negative pressure to spray the aluminum alloy wheel product. The firm adhesion and fixation facilitates quick positioning and fixation of aluminum alloy wheel products. On the other hand, users can select the corresponding color separation masking mold plate according to the shape of the aluminum alloy wheel product to be painted, and then use the snap-fit ​​fixing action formed by the fixing pins and fixing slots to assemble the color separation masking mold plate on the carrier frame. The spraying nozzle on the color separation masking mold plate will be aligned with a color gradient spraying area on the aluminum alloy wheel product. With the help of the masking baffle to shield and protect the edge of the spraying nozzle, it is convenient to assist users in color separation and zoning masking spraying when performing multi-color gradient spraying on aluminum alloy wheels.

With the help of the masking baffle 9 to shield and protect the edge of the spray coloring port 10, it is convenient to assist the user in performing color separation and zoning masking spraying when multi-color gradient spraying of aluminum alloy wheel.

A Y-shaped connecting pipe 18 connects the air intake pump 17 and the air exhaust pump 19. A rotary pipe joint 16 is provided between one end of the Y-shaped connecting pipe 18 and the air guide pipe 6. A pressure sensor 20 is installed on the Y-shaped connecting pipe 18.

[0032] The air guide pipe 6, the hub fixing rod 1, and the Y-shaped connecting pipe 18 are internally connected, and the Y-shaped connecting pipe 18 and the air guide pipe 6 form a rotatable connection.

[0033] In use, the user pre-selects the corresponding diameter wheel fixing rod 1 according to the size of the middle opening of the aluminum alloy wheel product and threads it to the front end of the air guide tube 6. In actual operation, the wheel fixing rod 1 is then inserted into the middle hole of the aluminum alloy wheel product.

In specific operation, starting the stepper motor 15, in conjunction with the transmission action of the worm gear 12 and worm wheel 14, can drive the air guide pipe 6 and the wheel hub fixing rod 1 to rotate. This can drive the aluminum alloy wheel product, which is adsorbed and fixed on the wheel hub fixing rod 1, to rotate accordingly. In addition, with the real-time position feedback of the stepper motor 15's shaft by the encoder 13, the stepper motor 15 can achieve quantitative driving of the angle through pulses. This allows the user to pre-input the rotation angle of the stepper motor 15 for each time into the PLC controller 21, so that the drive mechanism can drive the aluminum alloy wheel product to rotate at precise angles, so that the color separation areas on it face the spraying port 10 in sequence.
