[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 and Figure 2 An embodiment of this utility model provides: a quick-change grinding head for a grinding machine, including a cabinet 1 and a slider 9. A grinding machine 11 is fixedly connected to the lower surface of the slider 9. A clamping block 12 is fixedly connected to the output end of the grinding machine 11. A bolt 13 is threadedly connected inside the clamping block 12. A clamping block 14 is rotatably connected to the outer wall of the bolt 13. A sliding pin 15 is slidably connected inside the clamping block 12. A spring 16 is sleeved on the outer wall of the sliding pin 15. One end of the spring 16 is fixedly connected to the outer wall of the sliding pin 15, and the other end of the spring 16 is fixedly connected to the outer wall of the clamping block 12. A slot is opened inside the clamping block 12. A slot is opened inside the clamping block 14. A grinding head assembly is provided inside the clamping block 12. The grinding head assembly includes a clamping plate 17. The clamping plate 17 is slidably connected inside the slot of the clamping block 12. The clamping plate 17 is slidably connected inside the slot of the clamping block 14. A grinding head column 18 is fixedly connected to the lower surface of the clamping plate 17. A grinding head plate 19 is fixedly connected to the output end of the grinding head column 18.

[0024] Specifically, the clamping plate 17 is placed in the slot inside the clamping block 14 and the holding block 12. The bolt 13 is rotated, which causes the clamping block 14 to move closer to the holding block 12. This further pushes the sliding pin 15 into the interior of the holding block 12 and compresses the spring 16, thereby clamping and fixing the clamping plate 17 inside the clamping block 14 and the holding block 12. If disassembly is required, the bolt 13 is rotated, which causes the clamping block 14 to move and separate from the holding block 12. The spring 16 plays a resetting role, so that the clamping plate 17 is not clamped and fixed inside the clamping block 14 and the holding block 12, thus achieving the effect of facilitating quick replacement of the grinding head on the grinding machine.

[0025] Reference Figure 1 and Figure 2 A cover 2 is fixedly connected to the upper surface of the cabinet 1. A lifting frame 3 is fixedly connected to the lower surface of the cover 2. A motor 4 is fixedly connected to the outer wall of the lifting frame 3. A worm gear 5 is fixedly connected to the output end of the motor 4. A connecting column 6 is rotatably connected inside the lifting frame 3. A worm wheel 7 is fixedly connected to the lower surface of the connecting column 6. The worm wheel 7 meshes with the worm gear 5. A threaded rod 8 is fixedly connected inside the worm wheel 7. The threaded rod 8 is threadedly connected to the inside of the slider 9. A retaining strip 10 is fixedly connected to the outer wall of the slider 9. The retaining strip 10 is slidably connected to the inside of the lifting frame 3. A grinding groove 20 is opened inside the cabinet 1.

[0026] Specifically, the motor 4 is started, which drives the worm gear 5 to rotate. During the rotation of the worm gear 5, the worm wheel 7 rotates, which in turn drives the connecting column 6 and the threaded rod 8 to rotate. During the rotation of the threaded rod 8, the slider 9 and the clamping strip 10 rise and fall together, thereby driving the grinding machine 11 to rise and fall, achieving the effect of easy automatic lifting and adjustment.

[0027] Reference Figure 1 and Figure 3 A vacuum cleaner 21 is fixedly connected to the inner wall of the casing 2. A vacuum cleaner 22 is fixedly connected to the inside of the vacuum cleaner 21. A dust discharge pipe 23 is fixedly connected to the inside of the vacuum cleaner 21. The dust discharge pipe 23 is fixedly connected to the inside of the casing 2. A material pump 24 is fixedly connected to the inside of the cabinet 1. A water spray pipe 26 is fixedly connected to the output end of the material pump 24. A water tank 25 is fixedly connected to the inside of the cabinet 1. The material pump 24 is fixedly connected to the inside of the water tank 25. A water inlet pipe 27 is fixedly connected to the inside of the water tank 25. The water inlet pipe 27 is fixedly connected to the inside of the cabinet 1.

[0028] Specifically, dust is easily generated during the grinding process. The vacuum cleaner 21 is started, and the dust generated during grinding is sucked into the vacuum cleaner 21 through the suction pipe 22 and then discharged through the dust discharge pipe 23, achieving the effect of automatic dust removal. After grinding is completed, the material pump 24 can be started to extract water from the water tank 25 and spray it out through the water spray pipe 26, which can clean the inside of the grinding tank 20 and cool the grinding head plate 19. Water can be added to the inside of the water tank 25 through the water inlet pipe 27, thereby achieving the effect of automatic cleaning and cooling.

[0029] Working principle: When using the grinder, first place the raw material to be ground into the grinding tank 20, start the motor 4, which drives the worm gear 5 to rotate, then the worm gear 5 drives the worm wheel 7 to rotate, and the worm wheel 7 drives the threaded rod 8 to rotate. During the rotation of the threaded rod 8, the slider 9 moves up and down, and the sliding block 9 moves up and down, causing the clamping strip 10 to move up and down as well. The clamping strip 10 acts as a limit switch, thereby driving the grinding machine 11 to move up and down, achieving an automatic lifting and adjustment effect. Then start the grinding machine 11 to drive the clamping block 12 to rotate, thereby driving the grinding head column 18 and the grinding head plate 19 to rotate, achieving an automatic grinding effect. When the grinding head needs to be replaced, first turn the bolt 13. During the rotation, the bolt 13 slowly moves away from the inside of the clamping block 12, thereby causing the clamping block 14 to separate from the clamping block 12. At this time, the grinding head can be removed. Remove the head column 18 and grinding head plate 19, and replace them with brand new grinding head column 18 and grinding head plate 19. Place the grinding head column 18 in the slot inside the clamping block 14 and the holding block 12. Turn the bolt 13 to move the clamping block 14 closer to the holding block 12, thereby clamping and fixing the grinding head column 18 inside, achieving the effect of easy disassembly and replacement of the grinding head. Dust is easily generated during the grinding process. Start the vacuum cleaner 21 and suck the dust into the vacuum cleaner 21 through the vacuum pipe 22, and then discharge it through the dust discharge pipe 23. After grinding is completed, since the inside of the grinding tank 20 is relatively dirty and the temperature of the grinding head plate 19 is also high, start the material pump 24 to extract the water in the water tank 25. Clean and cool the grinding tank 20 and the grinding head plate 19 through the water spray pipe 26. When the water in the water tank 25 is used up, water can be injected into the water tank 25 through the water inlet pipe 27.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
