[0006] Preferably, the lifting beam is provided with a compressed air structure, one end of the compressed air structure is communicated with the air bag, and the other end is used for cooperating with a pressure reducing valve.

[0007] Preferably, the air bag is in the shape of a strip.

[0008] Preferably, the top surface of the sanding pad is flush with the top surface of the lifting beam.

[0009] Due to the use of the above technical scheme, the utility model has the following advantages compared with the prior art:

[0010] The utility model discloses a heavy -duty sander air bag type sanding pad mechanism, through setting up the structure that air bag cooperates with sanding pad, adjusts the pressure in the air bag through pressure reducing valve, changes the hardness of the sanding pad installed above the air bag, realizes that different hardness requirements can be adapted without replacing accessories, thereby improve production efficiency, can reduce sanding pad spare parts simultaneously, effectively reduce production cost. BRIEF DESCRIPTION OF DRAWINGS

[0011] The technical solution of this utility model will be further described below with reference to the accompanying drawings:

[0012] Appendix Figure 1 This is a schematic diagram of the structure of an airbag-type sanding pad mechanism for a heavy-duty sander according to the present invention;

[0013] Appendix Figure 2 For the appendix Figure 1 Enlarged view of point A in the middle.

[0014] In the diagram: 1. Guide roller; 11. Sanding belt; 2. Workpiece; 3. Lifting beam; 31. Groove structure; 32. Compressed air interface; 4. Airbag; 5. Sanding pad. Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] As attached Figures 1-2 As shown, the present invention provides a pneumatic sanding pad mechanism for a heavy-duty sander, comprising a guide roller 1 and a lifting beam 3; two guide rollers 1 are provided, and the two guide rollers 1 are rotatably mounted on the sander, and sanding belts 11 are sleeved on the two guide rollers 1, which are used to sand the workpiece 2. In this embodiment, the workpiece 2 is a sheet metal.

[0017] The lifting beam 3 is installed on the sander and is located between two sets of guide wheels. The lifting beam 3 has a groove structure 31, in which an airbag 4 and a sanding pad 5 are installed. The airbag 4 is located below the sanding pad 5. The sanding belt 11 is in contact with the top surface of the sanding pad 5. The workpiece 2 is engaged with the sanding belt 11 located on the top surface of the sanding pad 5. The top surface of the sanding pad 5 is flush with the top surface of the lifting beam 3 to fit the bottom surface of the workpiece 2. The airbag 4 is used to adjust the hardness of the sanding pad 5. In this embodiment, the airbag 4 is strip-shaped.

[0018] The lifting beam 3 is equipped with a compressed air interface 32. One end of the compressed air interface 32 is connected to the airbag 4, and the other end is used to cooperate with the pressure reducing valve. The pressure inside the airbag 4 is adjusted by adjusting the pressure reducing valve to change the volume of the airbag 4. When the air pressure inside the airbag 4 increases, the airbag 4 presses tightly against the sanding pad 5, which increases the hardness of the sanding pad 5. When the air pressure inside the airbag 4 decreases, the contact between the airbag 4 and the sanding pad 5 is looser, which reduces the hardness of the sanding pad 5, thereby adapting to different hardness requirements.

[0019] This application sets up a structure in which an airbag 4 and a sanding pad 5 cooperate. By adjusting the pressure inside the airbag 4 through a pressure reducing valve, the hardness of the sanding pad 5 installed above the airbag 4 can be changed. This allows for adaptation to different hardness requirements without the need to replace parts, thereby improving production efficiency and reducing the need for spare sanding pads 5, effectively lowering production costs.

[0020] The above is only a specific application example of the present application, and does not constitute any limitation on the protection scope of the present application; any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the present application.
