[0024] Reference Figure 1 In this embodiment, a hinge 15 is provided between one end of the top cover 2 and one side of the grinding box 1, and a connecting block 16 is provided between the other end of the top cover 2 and the other side of the grinding box 1. A fixing bolt 17 is provided between the two connecting blocks 16. The hinge 15 allows the top cover 2 to rotate on the top of the grinding box 1. After rotating and opening the top cover 2, the internal equipment of the grinding box 1 can be maintained. The fixing bolt 17 passes through the two connecting blocks 16 and is used to fix the top cover 2 to the top of the grinding box 1.

[0025] Reference Figure 2In this embodiment, inclined slides are provided on both sides of the support platform. Two filter frames 18 are slidably fitted inside the grinding box 1. The two filter frames 18 are located below the two inclined slides, and the two filter frames 18 correspond to the two recovery pipes 11. The filter frames 18 can filter single metal shavings in the cooling water. Pulling the filter frames 18 can remove them from the grinding box 1 for cleaning.

[0026] Reference Figure 3 In this embodiment, an annular baffle 19 is provided at the top of the annular channel 3. The two ends of the annular baffle 19 are respectively connected to the two sides of the movable block 4. The annular baffle 19 is made of rubber. The annular baffle 19 can block the annular channel 3 and prevent cooling water from entering the annular channel 3. The movement of the movable block 4 can drive the annular baffle 19.

[0027] Reference Figure 4 In this embodiment, the moving component 6 includes a motor 20 mounted on the bottom of the moving block 4, a gear 21 mounted on the output end of the motor 20, two racks 22 and two half-tooth rings 23 mounted in the annular groove 3. The two ends of the half-tooth rings 23 are respectively connected to one end of each of the two racks 22. The gear 21 meshes with the two racks 22 and the two half-tooth rings 23. The motor 20 drives the gear 21 to rotate, causing the gear 21 to mesh with the two racks 22 and the two half-tooth rings 23, thus moving the gear 21 along the racks 22 and the two half-tooth rings 23. The gear 21 drives the motor 20, which in turn drives the moving block 4, causing the moving block 4 to move along the annular groove 3. A cylinder is provided at the bottom of the annular groove 3, and the cylinder slides within the annular groove 3.

[0028] Reference Figure 5 The clamping assembly 9 in this embodiment includes a bidirectional lead screw 24 rotatably fitted within a fixed frame 8 and two clamping plates 25 slidably fitted within the fixed frame 8. Both ends of the bidirectional lead screw 24 are equipped with rotating wheels 26, and the bidirectional lead screw 24 is threadedly engaged with the two clamping plates 25. By rotating the rotating wheels 26, the bidirectional lead screw 24 can rotate, causing the two clamping plates 25 to move towards each other, thus clamping and fixing the blade.

[0029] Working principle: In use, first place the blade to be sharpened into the fixed frame 8, and use the clamping component 9 to clamp and fix the blade. At this time, the blade edge is facing down and passes through the slot 7. Multiple blades can be fixed into multiple fixed frames 8 respectively. Then, start the sharpening machine 5 and the moving component 6. The sharpening machine 5 will drive the sharpening wheel to rotate. The moving component 6 will drive the moving block 4 to move along the annular groove 3. The movement of the moving block 4 will drive the sharpening machine 5 to move, so that the sharpening machine 5 sharpens one side of the blade edge. At the same time, the water pump 13 is started to draw cooling water from the water tank 10, so that the cooling water is discharged through the connecting pipe 14 to the spray nozzle. The cooling water sprayed from the condenser 12 cools the blades and the grinding area of ​​the grinder 5. After the cooling water falls, it is recycled back to the water tank 10 through the recovery pipe 11. The grinder 5 can grind one side of the blade edge of multiple blades by moving. Then, the moving block 4 moves the grinder 5 from one side of the blade to the other side of the blade along the annular groove 3, so that the grinder 5 grinds the other side of the blade edge of multiple blades. When it is necessary to remove the ground blade, the clamping and fixing of the blade can be released after the grinder 5 moves away from the blade, the ground blade can be removed, and the blade to be ground can be put back in for grinding. The grinder 5 does not need to be stopped during the process.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
