DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4 A pulverizing device specially used for automatic spraying of molybdenum disulfide comprises a grinding barrel 1, a first grinding block 2 is fixedly installed in the grinding barrel 1, a U-shaped support frame 3 is installed on the grinding barrel 1, a rotating hole is opened on the support frame 3, a rotating column 4 is inserted in the rotating hole, and a second grinding block 5 is fixedly installed at the lower end of the rotating column 4;

[0023] A rectangular plate 6 is rotatably sleeved on the rotating column 4, and two positioning blocks 7 are fixedly sleeved on the rotating column 4. The two positioning blocks 7 are rotatably connected to the upper and lower surfaces of the rectangular plate 6 respectively. Circular holes are symmetrically opened on the support frame 3, and threaded rods 8 are slidably inserted in the two circular holes. The lower ends of the two threaded rods 8 are fixedly connected to the rectangular plate 6. Adjustment blocks 9 are threadedly sleeved on the two threaded rods 8, and the lower surface of the adjustment block 9 contacts the upper surface of the support frame 3.

[0024] When it is necessary to adjust the gap between the first grinding block 2 and the second grinding block 5, the two adjusting blocks 9 can be rotated at the same time. Since the adjusting block 9 is threadedly sleeved on the threaded rod 8, the threaded rod 8 will be driven to move up and down in the circular hole while the adjusting block 9 is rotated. The lower surface of the adjusting block 9 contacts the upper surface of the support frame 3, and the two threaded rods 8 drive the rotating column 4 to move up and down in the rotating hole through the rectangular plate 6, thereby driving the second grinding block 5 to move up and down through the rotating column 4, and then adjusting the gap between the first grinding block 2 and the second grinding block 5. Molybdenum disulfide particles of different coarsenesses can be ground by one device, effectively improving the practicality of the device.

[0025] A conical groove is formed on the lower surface of the second grinding block 5, a feeding hole connected to the conical groove is formed on the upper end of the rotating column 4, and a shaking handle 10 is fixedly mounted on the rotating column 4;

[0026] During grinding, the molybdenum disulfide to be ground can be put into the gap between the first grinding block 2 and the second grinding block 5 through the feed hole, and then the second grinding block 5 is driven to rotate by turning the crank handle 10 to achieve grinding and crushing of the molybdenum disulfide.

[0027] The grinding barrel 1 is symmetrically fixed with mounting blocks 11, and rectangular slots are provided on the two mounting blocks 11. The two ends of the support frame 3 are respectively inserted into the two slots. The support frame 3 can be disassembled by taking out the two ends of the support frame 3 from the two slots, so as to facilitate the cleaning of the first grinding block 2 and the second grinding block 5 after grinding.

[0028] The grinding barrel 1 is provided with a mounting hole, in which a square plate 12 is fixedly installed, one end of the square plate 12 is fixedly connected to the first grinding block 2, the upper surface of the square plate 12 is flush with the upper surface of the first grinding block 2, a moving rod 13 is vertically slidably installed on the grinding barrel 1 through an elastic component, the lower end of the moving rod 13 is flush with the lower surface of the second grinding block 5, and a transmission component for driving the moving rod 13 to move downward is provided on the grinding barrel 1, and the elastic component includes a fixed block 14 fixedly installed on the grinding barrel 1, a fixed sleeve The round block 15 on the moving rod 13 and the telescopic spring 16 sleeved on the moving rod 13, the fixed block 14 is provided with a moving hole, the moving rod 13 is slidably installed in the moving hole, the two ends of the telescopic spring 16 are respectively fixedly connected to the fixed block 14 and the round block 15, the transmission assembly includes a Z-shaped rod 17 fixedly installed on the upper end of the moving rod 13 and a retaining ring 18 fixedly sleeved on the second grinding block 5, one end of the Z-shaped rod 17 is located directly below the retaining ring 18, and the lower end of the moving rod 13 is flush with the lower surface of the Z-shaped rod 17;

[0029] Under the action of the elastic force of the telescopic spring 16, the moving rod 13 tends to move vertically upward, and in the process of the movement of the second grinding block 5, the retaining ring 18 will contact one end of the Z-shaped rod 17. Under the obstruction of the retaining ring 18, the lower surface of the Z-shaped rod 17 is flush with the lower surface of the second grinding block 5, and the lower end of the moving rod 13 is flush with the lower surface of the Z-shaped rod 17, so that the distance from the moving rod 13 to the square plate 12 is equal to the gap between the first grinding block 2 and the second grinding block 5. The gap between the first grinding block 2 and the second grinding block 5 can be judged by observing the gap between the bottom end of the moving rod 13 and the upper surface of the square plate 12. The observation is simple, so that the gap size control is more accurate.

[0030] In the utility model, when the gap between the first grinding block 2 and the second grinding block 5 needs to be adjusted, the two adjustment blocks 9 can be rotated at the same time to drive the threaded rod 8 to move up and down in the circular hole, and the two threaded rods 8 can then drive the rotating column 4 to move up and down in the rotating hole through the rectangular plate 6, thereby driving the second grinding block 5 to move up and down through the rotating column 4, thereby adjusting the gap between the first grinding block 2 and the second grinding block 5. Molybdenum disulfide particles of different coarsenesses can be ground through one device, effectively improving the practicality of the device.

[0031] In general, with respect to the technical problem: the existing powder grinding device can only grind molybdenum disulfide into particles of the same diameter during grinding. When it is necessary to grind it into particles of other diameters, it is necessary to replace a different crushing and grinding device, which is of low practicality. A technical solution is adopted: the gap between the first grinding block 2 and the second grinding block 5 can be adjusted by the mutual cooperation of the support frame 3, the rotating column 4, the rectangular plate 6, the threaded rod 8 and the adjusting block 9; because the implementation process of the technical solution is: when it is necessary to adjust the gap between the first grinding block 2 and the second grinding block 5, the two adjusting blocks 9 can be rotated at the same time to drive the threaded rod 8 to move up and down in the circular hole, and the two threaded rods 8 then drive the rotating column 4 to move up and down in the rotating hole through the rectangular plate 6, thereby driving the second grinding block 5 to move up and down through the rotating column 4, and then adjusting the gap between the first grinding block 2 and the second grinding block 5; so the technical problem can definitely be solved, and the technical effect achieved is: molybdenum disulfide particles of different coarsenesses can be ground through one device, effectively improving the practicality of the device.
