An independent polishing working chamber 10 and a wheel dressing and waxing working chamber 20 are provided inside the device main body 1. The device main body 1 is provided with a first dust suction port 43 and a second dust suction port 44. The first dust suction port 43 communicates with the polishing working chamber 10, and the second dust suction port 44 communicates with the wheel dressing and waxing working chamber 20; the polishing assembly is arranged in the polishing working chamber 10; the wheel dressing and waxing assembly is arranged in the wheel dressing and waxing working chamber 20; the polishing cloth wheel 2 is adapted to be switched between the polishing working chamber 10 and the wheel dressing and waxing working chamber 20; the dust suction port switching assembly 40 is connected to the device main body 1 and is used to control the opening and closing of the first dust suction port 43 and the second dust suction port 44 to achieve separate dust suction for the polishing working chamber 10 and the wheel dressing and waxing working chamber 20.

[0038] For the dust suction device 500 for polishing according to an embodiment of the present application, the polishing working chamber 10 and the polishing cloth wheel 2 cooperate to realize the polishing start of the workpiece 4 on the polishing working chamber 10, and then the wheel dressing and waxing working chamber 20 performs contour trimming and waxing treatment on the polishing cloth wheel 2. The opening and closing of the first dust suction port 43 and the second dust suction port 44 are switched and controlled through the dust suction port switching assembly 40 to complete separate dust suction and recycling treatment for the polishing working chamber 10 and the wheel dressing and waxing working chamber 20, reducing the safety risk, preventing artificial inhalation of dust, further protecting the physical health of workers, and finally meeting the environmental protection requirements of green manufacturing.

[0039] It can be understood that the independent polishing working chamber 10 and the wheel dressing and waxing working chamber 20 effectively avoid the mutual contamination of the dust generated during the polishing process and the possible wax chips generated during the wheel dressing and waxing process, ensuring the processing quality and the cleanliness of the equipment.

[0040] During the polishing process, a large amount of dust and debris will be generated. Through the dust suction port switching component 40, it can be ensured that when polishing operations are carried out in the polishing working chamber 10, the first dust suction port 43 is opened and effective dust suction is carried out; while when dressing and waxing operations are carried out in the dressing and waxing working chamber 20, the second dust suction port 44 is opened and effective dust suction is also carried out. This design not only improves the dust suction efficiency, but also avoids the accumulation of dust inside the device, reducing the safety risk.

[0041] The dust suction port switching component 40 can precisely control the opening and closing of the first dust suction port 43 and the second dust suction port 44, ensuring that the dust suction operations of each working chamber can be carried out independently, and the dust suction area can be flexibly adjusted according to the actual processing requirements, thereby improving the dust suction effect of the polishing working chamber 10 and the dressing and waxing working chamber 20 and avoiding dust diffusion. There is no need to additionally increase dust suction equipment or use a vacuum cleaner 700 with a larger air volume, reducing the equipment procurement and maintenance costs.

[0042] In one embodiment, please refer to Figures 1 to 5 , the polishing component includes a special fixture 3, the special fixture 3 is arranged inside the polishing working chamber 10, and the special fixture 3 is used to clamp the workpiece 4 to be processed.

The outlet of the dust suction channel 30 is the first dust suction port 43, and the first dust suction port 43 and the second dust suction port 44 are arranged on the same side of the device main body 1.

[0044] When the polishing dust suction device 500 is externally connected to a vacuum cleaner 700, the dust generated in the polishing working chamber 10 first passes through the dust discharge port and then reaches the first dust suction port 43 along the dust suction channel 30. The first dust suction port 43 and the second dust suction port 44 are arranged on the same side of the device main body 1, reducing the switching difficulty of the dust suction port switching component 40, where the "switching difficulty" can be understood as the complexity of the dust suction port switching component 40 in operation, maintenance and technical implementation.

[0045] For example, since the first dust suction port 43 and the second dust suction port 44 are located on the same side of the device main body 1, the dust suction port switching component 40 can adopt a simpler mechanical structure (such as a sliding valve or a rotary baffle) to realize the opening and closing of the first dust suction port 43 and the second dust suction port 44. This design not only reduces the manufacturing cost of the equipment, but also improves the reliability of the switching operation. On the other hand, the same-side arrangement of the dust suction ports enables the switching of the first dust suction port 43 and the second dust suction port 44 to be completed at the same position, without moving the equipment or adjusting the connection position of the vacuum cleaner 700.

The dust suction port switching box 41 is connected to the device main body 1, and the dust suction port switching box 41 is provided with an outlet; the switching slide plate 46 is slidably connected to the dust suction port switching box 41, and the switching slide plate 46 is provided with an opening; the driving assembly 45 is adapted to drive the switching slide plate 46 to slide to switch between a first state and a second state. In the first state, the switching slide plate 46 retracts, the switching slide plate 46 does not block the first dust suction port 43, and at the same time, the opening on the switching slide plate 46 is not communicated with the second dust suction port 44, so that the first dust suction port 43 is communicated with the outlet, and the connection between the second dust suction port 44 and the outlet is disconnected. In the second state, the switching slide plate 46 extends, the switching slide plate 46 blocks the first dust suction port 43, and at the same time, the opening on the switching slide plate 46 is communicated with the second dust suction port 44, so that the opening is communicated with the second dust suction port 44 and the outlet, and the connection between the first dust suction port 43 and the outlet is disconnected.

[0067] According to the dust suction port switching unit for polishing in the embodiment of the present application, through the sliding control of the switching slide plate 46, the dust suction port switching unit for polishing can concentrate the dust suction air volume in one area (such as the polishing area or the waxing area of the wheel repair), thereby improving the dust suction effect in this area and avoiding dust diffusion. There is no need to additionally increase dust suction equipment or use a vacuum cleaner 700 with a larger air volume, reducing the equipment procurement and maintenance costs. The rapid switching of the dust suction port is realized through the driving assembly 45, the operation is simple, the dust suction area can be flexibly adjusted according to the actual processing requirements, the dust can be effectively collected, the environmental pollution is reduced, the risk of the operator inhaling dust is reduced, and the health is guaranteed.

[0068] It can be understood that the dust suction port switching box 41 is internally provided with an outlet, a first dust suction port 43, and a second dust suction port 44. The outlet is used to connect to the vacuum cleaner 700 or the dust suction pipe of the vacuum cleaner 700. Specifically, it can be connected to the internal dust suction pipeline 50 of the machine through an adapter 42, and then connected to the vacuum cleaner 700 through the internal dust suction pipeline 50 of the machine. The first dust suction port 43 and the second dust suction port 44 are used to collect dust generated in different areas. In one embodiment, one of the first dust suction port 43 and the second dust suction port 44 corresponds to the polishing working chamber 10, and the other corresponds to the waxing working chamber 20 of the wheel repair.

[0069] The switching slide plate 46 is slidably connected inside the dust suction port switching box 41.

At the same time, the opening is not aligned with the second dust suction port 44, so that the dust in the polishing area enters the dust suction port switching box 41 through the first dust suction port 43 and is transported to the vacuum cleaner 700 through the outlet. At this time, the second dust suction port 44 is disconnected from the outlet, improving the dust suction efficiency of the first dust suction port 43.

[0070] When dressing the polishing cloth wheel 2 and waxing it, the switching slide plate 46 slides to the second state, the switching slide plate 46 extends, so that the opening is aligned with the second dust suction port 44. At the same time, other parts of the switching slide plate 46 cut off the connection between the first dust suction port 43 and the outlet, so that the dust in the dressing and waxing area enters the dust suction port switching box 41 through the second dust suction port 44 and is transported to the vacuum cleaner 700 through the outlet. At this time, the first dust suction port 43 is disconnected from the outlet, improving the dust suction efficiency of the second dust suction port 44.

[0078] In one embodiment, the driving cover plate 47 is in a plate-like structure. The receiving space is surrounded by the inner wall of the driving cover plate 47 and the dust suction port switching box 41. When the driving component 45 works, it drives the switching slide plate 46 to slide in the receiving space to control the communication state between the opening and the first dust suction port 43 or the second dust suction port 44.

[0079] In one embodiment, the driving cover plate 47 is fixed to one side of the dust suction port switching box 41 by bolts, buckles or other connection means to form a closed receiving space.
