Working principle: Put the solid electrolyte material to be crushed into the crushing box 1, start the first motor 3, and then the crushing shaft 4 rotates and the electric crushing rod 2 rotates, so as to crush the material inside the crushing box 1. After the crushing is completed , open the valve 6, and the material located inside the crushing box 1 enters the inside of the second outer box 10 from the discharge pipe, and the material enters the inside of the second outer box 10 from the rectangular opening at the top of the second outer box 10, along with the second As the material inside the outer box 10 continues to increase, the vertical plate 20 moves downward. When the raw material inside the second outer box 10 reaches the preset value, the pressure rod 5 just comes into contact with the switch 12, and the valve 6 is closed, blocking the material from entering the second outer box 10. The inside of the second outer box 10 drives the fourth motor 7 to rotate, which can drive the second outer box 10 to rotate along the third hinge shaft, so that the side where the baffle plate 9 is located is downward, and the second electric push rod 23 is started, Then the scraper 22 moves to the side where the baffle plate 9 is located, and the baffle plate 9 at this moment contacts the spherical protrusion 24, so that the side plate 21 moves away from the side where the baffle plate 9 is located, and moves away from the side where the baffle plate 9 is located. When the side plate 21 is close to the side where the rectangular groove 25 is located, it moves away from the side where the clamping hole is located. Finally, the clamping column 38 leaves the inside of the clamping hole, and then the baffle plate 9 rotates along the hinge, and the opening on the second outer box 10 is opened, the material enters the inside of the first outer box 16 from the opening on the second outer box 10, the material enters the inside of the first outer box 16 from the top of the first outer box 16, starts the second motor 17, then the second The second motor 17 can drive the cover plate 39 to rotate along the axial direction of the second hinge shaft to realize the closing of the cover plate 39. At this time, the fifth motor 44 is driven forward and reverse, and the gear 15 rotates thereupon. The bar 37 is meshed, and the sliding cylinder 45 is not in contact with the gear 15. At this time, the gear 15 can reciprocate along the axial direction of the rack 37, and the grinding roller 36 moves with the gear 15, so that the The material is ground, and the third motor 13 is driven at a very small forward and reverse angle during grinding, so that when the grinding roller 36 is grinding, the first outer box 16 itself shakes, and the material inside the first outer box 16 is shaken to improve the grinding speed. effect, the distance between the bottom plate 50 and the grinding roller 36 can be gradually reduced during grinding, so that the material can be ground more fully. After the grinding is completed, the third motor 13 is started to drive the first outer box 16 to rotate to a vertical position. When the side where the first screen 26 and the second screen 28 are located is vertically downward, start the first electric push rod 48, the first electric push rod 48 stretches and drives the first outer box 16 to vibrate, and the material particles that meet the requirements are released from the The filter hole 33 that the first screen cloth 26 and the second screen cloth 28 inner chambers offer is poured out, and the unqualified material still stays in the inside of the first outer box 16, and the material particle size of discharging like this is consistent, and all meet the requirements , you can.
