[0029] See Figure 3 and Figure 4 The side wall of the air nozzle 19 is fixedly equipped with an abutment plate 24, and the abutment plate 24 and the support plate 13 are distributed on both sides of the sanding belt body 7. The storage box 23 is located below the slot 17, and the sanding belt body 7 is arranged on the inner wall of the slot 17, so that the abutment plate 24 can abut one side of the sanding belt body 7 to ensure that the sanding belt body 7 will not be concave when the sanding workpiece is squeezed. It can form an effective support for the sanding belt body 7, and the debris dropped by the sanding belt body 7 when the sanding belt body 7 is grinding the workpiece can directly fall into the inner cavity of the storage box 23 through the slot 17 for collection, ensuring that it will not fall at will.

[0030] See Figure 1The inner walls of the two frames 8 are each provided with a through hole, and the inner walls of the through holes are threadedly connected with a self-tightening bolt 16. The self-tightening bolt 16 passes through the through hole and is threadedly connected to the inner wall position of the connecting hole 15, so that the self-tightening bolt 16 can be used to cooperate with the connecting hole 15 to stably install the slide bar 1 9 and the slide bar 2 14 on the inner wall position of the two frames 8, and the position of the slide bar 1 9 and the slide bar 2 14 on the inner wall of the frame 8 can be slid to adjust the tightness of the sanding belt body 7.

[0031] See Figure 2 and Figure 3 The top of the positioning plate 2 is fixedly equipped with a support arm 3, the inner wall of the support arm 3 is fixedly equipped with a ball bearing, and the inner wall of the ball bearing is fixedly connected to the auxiliary wheel 1 4, and the sanding belt body 7 is sleeved on the outer edge of the auxiliary wheel 1 4 and the two auxiliary wheels 2 11, so that the stability of the sanding belt body 7 when running at the outer edge of the auxiliary wheel 1 4 can be guaranteed, and it can be ensured that it will not easily fall off, and the sanding belt body 7 can be used at the outer edge of the auxiliary wheel 2 11 to grind arc-shaped workpieces, thereby improving the scope of use.

[0032] See Figure 5 The sealing cover 20 is arranged at the top position of the dust collecting bin 22. The inner cavity of the dust collecting bin 22 is provided with an air pump, and the output end of the air pump is fixedly connected to the end of the air pipe 18 close to the sealing cover 20. There are several air outlet holes distributed in a ring on the top of the sealing cover 20, and the filter cotton plate 21 is arranged at the bottom position of the several air outlet holes. The dust collecting bin 22 is arranged at the top position of the base plate 1, so that the air pump can be driven to operate and the air nozzle 19 can be used to absorb the dust generated when the workpiece is polished into the inner cavity of the dust collecting bin 22 through the air pipe 18, and then the dust absorbed into the inner cavity of the dust collecting bin 22 is filtered through the filter cotton plate 21. The filtered clean gas can be discharged to the outside through the air outlet to ensure that dust will not fly all over the sky during polishing, and to prevent the staff from inhaling it into the lungs and threatening their lives.

[0034] See Figure 3 and Figure 4 The sizes of slide bar 1 9 and slide bar 2 14 are adapted to the inner wall size of frame 8 , so that when slidingly adjusting the positions of slide bar 1 9 and slide bar 2 14 , slide bar 1 9 and slide bar 2 14 will not slide easily and can maintain stable translation.

[0035] Working principle: When using this device, the workpiece to be polished can be placed on the top of the support plate 13, and the plane of the workpiece can be polished by using the vertical sanding belt body 7, and the arc-shaped workpiece can be polished by using the sanding belt body 7 on the outer edge of the auxiliary wheel 2 11, which increases the scope of use. The debris during polishing can directly fall into the inner cavity of the storage box 23 through the notch 17 for collection, ensuring that it will not fall at will. At the same time, the air pump can be driven to run, and the dust generated when polishing the workpiece can be absorbed into the air pipe 18 by using the air nozzle 19. The inner cavity of the dust collecting bin 22 is filtered through the filter cotton plate 21 to process the dust absorbed in the gas in the inner cavity of the dust collecting bin 22. The filtered clean gas can be discharged to the outside through the air outlet to ensure that the dust will not fly all over the sky during grinding, and to prevent the staff from inhaling it into the lungs and threatening their life safety. After removing the self-tightening bolt 16, the sliding slide bar 1 9 and the sliding slide bar 2 14 can be moved to the position of the inner wall of the frame 8, so as to adjust the tightness of the sanding belt body 7, and it is convenient to remove the sanding belt body 7 for replacement, so there is no need to pull it hard, which improves the convenience of replacement.
