[0028] The working principle of the present application is: The prepared various raw materials of the aluminum-cement carbon brick are respectively poured into the inside of the inner guide hopper 202 and the outer guide hopper 203, the lightweight aggregate with larger particle size and other substances with larger particle size fall into the inside of the inner cylinder 302, and other lightweight raw materials enter the inside of the outer cylinder 303 along with the outer guide hopper 203, and are driven to rotate along with the output end of the drive motor 6, so that the transmission plate 311 and the disintegration sleeve 314 start to rotate, the harder and larger particle size raw materials are crushed by the crushing blocks on the outer surface of the disintegration sleeve 314, and then the crushed raw materials are mixed with the remaining raw materials flowing in the outer cylinder 303; With the rotation of the transmission plate 311 and the driving of the crushing plate 306 through the sealing sleeve 305, the crushing plate 306 repeatedly moves up and down under the action of the corrugated ring 310, and further crushes the raw materials above the sieve plate 307, and realizes the mixing effect of the raw materials, and then the crushed raw materials flow down along the sieve holes on the outer surface of the sieve plate 307, and then fall into the inside of the mixing cylinder 4; At this time, the raw materials falling from the decomposition sleeve 314 fall above the isolation umbrella 403, and as the raw materials accumulate, the isolation umbrella 403 and the supporting plate 502 move downward, and then move downward with the supporting plate 502, so that the connecting ring 501 also moves downward at the same time, and the passive sleeve 402 also moves downward at the same time, and drives the connecting sleeve 405 to move, and then the connecting sleeve 405 is in contact with the outer surface of the pressure receiving sleeve 407, and as the raw materials accumulated above the isolation umbrella 403 increase, the pressure receiving spring 412 inside the pressure receiving sleeve 407 is compressed, and as the pressure receiving sleeve 407 moves downward, the pressure receiving spring 412 is completely compressed, and the passive pipe 406 continuously moves downward, so that the spiral groove on the outer surface of the pressure receiving sleeve 407 drives the unlocking ring 503 to rotate, and as the unlocking ring 503 rotates, the limiting rod 504 moves away from the supporting plate 502, at this time the supporting plate 502 is no longer limited, and starts to rotate, allowing the aluminum carbon brick raw materials above the isolation umbrella 403 to fall along the edge of the center cylinder 308 (the supporting plate 502 can only rotate at a small angle, which can allow the raw materials accumulated above the isolation umbrella 403 to fall slowly), which falls on the raw materials inside the mixing cylinder 4 to achieve more sufficient mixing effect, avoid uneven mixing and high porosity phenomenon; Then the raw materials in the center cylinder 308 enter the inside of the movable bin 106 along the guide pipe 107, and then the movable bin 106 moves to the upper side of the mold box 105, at this time the raw materials in the movable bin 106 enter the inside of the mold box 105, and then the movable bin 106 returns to the initial position, and then the mold box 105 is sealed by the pressing cover 104, and then the raw materials in the mold box 105 are extruded by the hydraulic machine 101 to form the aluminum carbon brick semi-finished product, and then the pressing cover 104 is opened, and the semi-finished product is pushed to the upper side of the supporting plate 3 by the push plate 108; At this time, due to the decrease of the raw materials above the isolation umbrella 403, the pressure receiving sleeve 407 moves upward under the elastic force of the pressure receiving spring 412, and then the supporting plate 502 also returns to the initial position under the action of the torsional spring, and at this time the unlocking ring 503 moves upward under the elastic force of the auxiliary spring 505, so that the unlocking ring 503 returns to the initial position, and the unlocking ring 503 moves upward and starts to rotate in the opposite direction of the initial downward direction, and drives the limiting rod 504 to return to the initial position, and waits for the next trigger.
