[0025] Example 1

[0026] The technical solution in the embodiment of the present application is to effectively solve the technical problems of low precision and low working efficiency of the existing transmission belt side grinding device during use. The overall idea is as follows:

[0027] A device for grinding the side of a transmission belt, the grinding device comprises a workbench 4; a fixing mechanism, fixedly mounted on the upper surface of the workbench 4, the fixing mechanism comprising a hollow cylindrical rod 8, an L-shaped pillar 7, a solid cone 14, a telescopic rod 20 and a buckle 21, the hollow cylindrical rod 8 is movably embedded in the interior of the workbench 4, the number of the L-shaped pillars 7 is multiple, and the multiple L-shaped pillars 7 are regularly and movably embedded in the interior of the hollow cylindrical rod 8, one end of the multiple L-shaped pillars 7 is fixedly connected to the telescopic rod 20, one end of the telescopic rod 20 is fixedly connected to the buckle 21, the outlet diameter of the hollow cylindrical rod 8 near the top is an internal thread, which cooperates with the external thread of the solid cone 14; wherein, a transmission belt 6 is arranged around the outer surface of the multiple L-shaped pillars 7, and the length of the telescopic rod 20 is changed by the spiral up and down movement of the solid cone 14, so that the transmission belt 6 is firmly sleeved on the outer surface of the L-shaped pillar 7 to achieve a fixing effect.

[0028] In some examples, a connecting shaft 18 is fixedly disposed on the upper surface of the solid cone 14, and a rotating disk 15 is fixedly mounted on one end of the connecting shaft 18. Figure 5 As shown, the solid cone 14 can be made to perform spiral motion with less effort. A motor 19 for driving the hollow cylindrical rod 8 to rotate is fixedly mounted on the lower surface of the workbench 4. Figure 1 As shown, under the action of the motor 19, the hollow cylindrical rod 8 is driven to rotate, and then when the sharpening knife 9 is stationary, the transmission belt 6 realizes the grinding of the edge by self-rotation.

[0029] During the specific implementation process, when it is necessary to grind the edge of the transmission belt 6, the transmission belt 6 is first sleeved on the outer surface of the L-shaped pillar 7, and then the turntable 15 is rotated to make the solid cone 14 and the hollow cylindrical rod 8 spirally move, thereby changing the diameter of the arc formed by multiple L-shaped pillars 7 to firmly support and fix the transmission belt 6. At this time, the motor 19 is connected to the external power supply to realize the rotation of the hollow cylindrical rod 8, that is, the relative rotation of the transmission belt 6 is realized. Finally, the staff rotates the rocker handle 1, and through the cooperation of the external thread of the threaded rod 2 and the internal thread of the threaded block 17, under the action of the limit block 12, the grinder 9 is moved closer to the transmission belt 6, thereby realizing the grinding of the side of the transmission belt 6.

Figure 2 As shown, the sharpener 9 is connected to the fixed rod 11 and moves in the movable groove 13, which not only frees the hands of the staff, but also allows the sharpener 9 to move toward the support plate 3 during the removal of the transmission belt 6 to protect the personal safety of the staff. A threaded rod 2 is movably embedded in the interior of the fixed rod 11, one end of the threaded rod 2 is fixedly connected to the rocker handle 1, and the other end of the threaded rod 2 is threadedly connected to the inner wall of the fixed rod 11, and the outer surface of the threaded rod 2 is sleeved with a threaded block 17, as shown in FIG. Figure 4 As shown, the position of the sharpening knife 9 can be moved more labor-savingly and accurately.

The lower surface of the threaded block 17 is fixedly connected to the first connecting rod 10, and the bottom of the first connecting rod 10 is fixedly installed with a sharpening knife 9. Figure 4 As shown, when the threaded rod 2 rotates, the threaded block 17 drives the grinding knife 9 to move.
