An adjusting bolt 7 is provided inside the adjusting table 6, and the right side of the adjusting bolt 7 extends into the inside of the lifting groove 5. A lifting plate 8 is provided inside the lifting groove 5, a top frame 9 is installed at the top end of the lifting plate 8, and a second rotating shaft 10 is installed on the left side of the top frame 9. A grinding belt 11 is provided on the outer sides of the first rotating shaft 4 and the second rotating shaft 10;

[0025] Specifically, as Figure 1 , Figure 2 and Figure 3As shown in the figure, when in use, turn the two sets of adjusting bolts 7 at the top right of the frame 2 until they are loose, and the fixation of the inner lifting plate 8 can be released. At this time, the lifting plate 8 can move up and down along the lifting groove 5. By means of the up and down movement of the lifting plate 8, the height of the upper second rotating shaft 10 can be adjusted, thereby adjusting the distance between the second rotating shaft 10 and the first rotating shaft 4. After the adjustment is completed, tighten the adjusting bolt 7 again. As the front end of the adjusting bolt 7 abuts against the surface of the lifting plate 8, the lifting plate 8 is fixed;

[0026] Receiving grooves 12 are provided on the outer side walls of the first rotating shaft 4 and the second rotating shaft 10. A number of receiving grooves 12 are provided on the outer side walls of the first rotating shaft 4 and the second rotating shaft 10, and the number of receiving grooves 12 are distributed in a ring shape. A sliding groove 13 is provided on the left side of the receiving groove 12, a slider 14 is provided inside the sliding groove 13, the right side of the slider 14 extends into the receiving groove 12, a limiting plate 15 is installed on the right side of the slider 14, and two sets of springs 16 are installed at the bottom end of the limiting plate 15. The two sets of springs 16 are symmetrically distributed;

[0027] Specifically, as Figure 1 , Figure 2 and Figure 4 shown, when in use, with the assistance of the spring 16, the limiting plate 15 protrudes from the outer surfaces of the first rotating shaft 4 and the second rotating shaft 10. With the help of the limiting plate 15, the position of the grinding belt 11 can be limited. By sliding the outer slider 14, the position of the limiting plate 15 can be driven to move. After moving the limiting plate 15 to the inside of the receiving groove 12 for hiding, the installation or disassembly operation of the grinding belt 11 can be carried out;

[0028] A clamping block 17 is provided at the front end of the frame 2. A placing table 18 is fixed on the left side of the clamping block 17, a fixing table 19 is fixed on the right side of the clamping block 17. A fixing bolt 20 is provided inside the fixing table 19, the left side of the fixing bolt 20 extends to the inside of the clamping block 17, internal threads are provided inside the fixing table 19, and external threads are provided on the surface of the fixing bolt 20;

[0029] Specifically, as Figure 2 and Figure 5 shown, when in use, the cross-section of the clamping block 17 is slightly larger than the cross-section of the frame 2. After the clamping block 17 is stuck on the frame 2, it can slide up and down along the frame 2 to adjust the height position of the placing table 18. After adjusting the placing table 18 to the appropriate height, tighten the fixing bolt 20. The inner side of the fixing bolt 20 abuts against the surface of the frame 2 to fix the positions of the clamping block 17 and the placing table 18;

After driving the limiting plate 15 to move inside the storage groove 12, the grinding belt 11 can be sleeved outside the first rotating shaft 4 and the second rotating shaft 10 for installation. After the installation is completed, the slider 14 is released, and the limiting plate 15 moves to the outside with the assistance of the spring 16. With the aid of multiple protruding limiting plates 15, the grinding belt 11 can be limited to prevent the grinding belt 11 from falling off. After that, the adjusting bolt 7 at the top right of the frame 2 can be loosened, and the lifting plate 8 is moved up and down to adjust the height position of the upper second rotating shaft 10. By adjusting the distance between the second rotating shaft 10 and the first rotating shaft 4, the tightness of the outer grinding belt 11 is adjusted. After the adjustment is completed, the adjusting bolt 7 is tightened. Finally, the installation of the placement table 18 can be carried out. During installation, first, the clamping block 17 is clamped on the frame 2 and then moved up and down along the frame 2. After the height adjustment is completed, the fixing bolt 20 at the side end is tightened. After the clamping block 17 is fixed, the product to be ground is placed on the placement table 18 and moved towards the grinding belt 11 along the placement table 18. When the motor 3 drives the first rotating shaft 4 to rotate, the outer grinding belt 11 can be driven to rotate. When the surface of the product comes into contact with the rotating grinding belt 11, grinding treatment can be carried out.
