[0024] 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.

[0025] Reference Figures 1 to 5An airtight structure for a grinding machine and the grinding machine itself, comprising a housing 2, a grinding barrel 10 embedded in the upper surface of the housing 2, a connecting plate 13 located at the lower end near the midpoint of the inner surface of the grinding barrel 10, a first grinding plate 12 rotatably mounted on the upper surface of the connecting plate 13, an upper sealing cap 11 threadedly mounted at the midpoint of the upper surface of the first grinding plate 12, a second grinding plate 16 rotatably mounted on the lower surface of the connecting plate 13, and a lower sealing cap 15 threadedly mounted at the midpoint of the lower surface of the second grinding plate 16;

[0026] A fixed housing 19 is embedded and fixed at the midpoint of the connecting plate 13. A second servo motor 23 is fixedly installed inside the fixed housing 19. A second bevel gear 22 is fixedly installed at the output end of the second servo motor 23. A fixed rod 18 is rotatably embedded on one side of the upper end face of the fixed housing 19. A connecting rod 20 is rotatably embedded on one side of the lower end face of the fixed housing 19. A cover plate 1 is snapped onto the upper end face of the fixed housing 19.

[0027] Specifically, after the connecting plate 13 is positioned at the lower end of the midpoint of the inner surface of the grinding barrel 10, the first grinding plate 12 and the second grinding plate 16 can be rotatably mounted on the upper and lower ends of the connecting plate 13, respectively. The gap between the rotatably mounted first grinding plate 12 and the inner top surface of the grinding barrel 10 gradually decreases from top to bottom, and the gap between the second grinding plate 16 and the inner bottom surface of the grinding barrel 10 also gradually decreases from top to bottom. This allows the first grinding plate 12 and the second grinding plate 16 to better grind the material. Meanwhile, on the first grinding plate 12... The upper sealing cover 11 and the lower sealing cover 15, which are respectively rotatably embedded on the end face and the lower end face of the second grinding plate 16, can effectively seal the connection between the first grinding plate 12 and the second grinding plate 16, thereby preventing the dust generated during grinding from affecting the drive structure of the grinding machine. After the second servo motor 23 is installed in the fixed housing 19 embedded at the midpoint of the upper end face of the connecting plate 13, the second servo motor 23 can drive the first grinding plate 12 and the second grinding plate 16 to rotate simultaneously, thereby better grinding the material.

[0028] Reference Figure 5 The lower end face of the fixed rod 18 and the upper end face of the connecting rod 20 are both fixedly provided with a first bevel gear 17. The two first bevel gears 17 are respectively meshed with the upper end and the lower end of the second bevel gear 22.

[0029] Specifically, after the first bevel gear 17 is fixedly installed on the lower end face of the fixed plate and the upper end face of the connecting rod 20, it can mesh with the second bevel gear 22 fixedly installed on the output end of the second servo motor 23. This allows the second servo motor 23 to drive the first grinding plate 12 and the second grinding plate 16 to rotate better. At the same time, when the second bevel gear 22 rotates, the two second bevel gears 22 can drive the first grinding plate 12 and the second grinding plate 16 to move in opposite directions, thereby better grinding the material.

[0030] Reference Figure 5 The first grinding plate 12 is fixedly sleeved on the upper part of the outer surface of the fixed rod 18. Four threaded rods 21 are fixedly installed on the lower end face of the connecting rod 20. All four threaded rods 21 are threaded through the midpoint of the lower end face of the second grinding plate 16.

[0031] Specifically, after the first grinding plate 12 is fixedly sleeved on the outer surface of the fixing rod 18, the first grinding plate 12 and the fixing rod 18 can be further fixed by bolts. At the same time, after the lower end face of the connecting plate 13 is fixedly embedded through the midpoint of the upper end face of the second grinding plate 16, the second grinding plate 16 can be rotated more effectively. Meanwhile, the nut sleeved on the outer surface of the threaded rod 21 can better fix the second grinding plate 16 and the connecting rod 20.

[0032] Reference Figure 3 and Figure 4 Fixing blocks 14 are fixedly installed on the outer surface of the connecting plate 13 at the front end, rear end and both sides. The four fixing blocks 14 are fixedly installed on the inner surface of the grinding barrel 10 on the side away from the connecting plate 13.

[0033] Specifically, by fixing the fixing blocks 14 on the outer surface of the connecting plate 13 near the front end, the rear end, and both sides, the connecting plate 13 can be better fixed on the inner surface of the grinding barrel 10.

[0034] Reference Figure 1 and Figure 2 A fixing frame 7 is fixedly installed at the midpoint of the upper surface of the equipment shell 2. A first servo motor 5 is fixedly installed at the midpoint of the upper surface of the fixing frame 7. A rotating shaft 8 is fixedly installed at the output end of the first servo motor 5.

[0035] Specifically, after the mounting bracket 7 is fixedly installed on the upper surface of the equipment housing 2, the first servo motor 5 can be embedded and fixedly installed on the upper surface of the mounting bracket 7. At the same time, the output end of the first servo motor 5 can be fixedly connected to the rotating shaft 8, so that the first servo motor 5 can drive the rotating shaft 8 to rotate.

[0036] Reference Figure 2The rotating shaft 8 rotates through the upper surface of the cover plate 1. The outer shell of the rotating shaft 8 is fixedly fitted with a stirring blade 9 at the lower end. The upper surface of the cover plate 1 is embedded and fixedly fitted with a feed hopper 4 at the rear end.

[0037] Specifically, after the rotating shaft 8 is rotated through the upper end face of the cover plate 1, the stirring blade 9 can be fixedly sleeved on the outer surface of the rotating shaft 8 inside the equipment housing 2. When the rotating shaft 8 rotates, it can drive the stirring blade 9 to stir and transport the material in the grinding barrel 10. At the same time, the fixedly embedded feed hopper 4 can better put the material into the grinding barrel 10 for grinding.

[0038] Reference Figure 1 A storage box 6 is movably embedded in the lower end of the front face of the fixed outer shell 19, and foot pads 3 are fixedly installed on both sides of the lower end face of the fixed outer shell 19 near the front and rear ends.

[0039] Specifically, after the storage box 6 is movably embedded in the lower end of the front face of the equipment shell 2, the ground material powder can be stored. After the storage box 6 is pulled out, the material powder can be discharged and used more effectively. The foot pad 3 fixedly installed on the lower end face of the equipment shell 2 can support the grinder and prevent slippage.

[0040] Working principle: During use, the user can put the material to be ground into the grinding barrel 10 embedded inside the outer shell 2 of the equipment through the feeding hopper 4. At the same time, the user can start the first servo motor 5 to drive the stirring blade 9 to rotate, so that the material is stirred and conveyed at the upper end of the grinding barrel 10. After starting the second servo motor 23, the first grinding plate 12 and the second grinding plate 16 can be driven to rotate through the second bevel gear 22, so that the put-in material can be ground. The ground material powder can be discharged into the storage box 6 for storage.

[0041] 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.
