[0041] After the raw materials of the concrete aerated brick are processed and stirred, slurry is formed and injected into the inner wall of the mold box 219, and then the cover plate control mechanism 4 is started to cover the cover plate 47 to the top of the mold box 219, and the slurry is formed on the inner wall of the mold box 219. After the forming is completed, the cover plate control mechanism 4 is started to lift the cover plate 47 off the top of the mold box 219, and then the double-axis motor 36 is started to make the conical gear 37 drive the second conical gear 38 to rotate, and then drive the screw 39 to rotate. With the rotation of the screw 39, the transmission block 310 moves on the screw 39, pushing the push plate 34 to move to the left, and the push plate 34 pushes the push plate 312 to move to the left on the inner wall of the slide plate 31 through the push plate push rod 311;

[0042] When the two transmission blocks 310 and the push plate 34 push the push plate 312 to move leftward on the inner wall of the slide plate 31, the two transmission blocks 310 drive the push-pull rod connecting rod 35 to move leftward, and the push-pull rod connecting rod 35 drives the two push-pull rods 226 to move leftward. The leftward movement of the push-pull rod 226 causes the slide bar 225 to slide on the top inner wall of the slide groove plate 212, and then the inclined surface of the inclined slide plate 223 and the reverse inclined slide groove plate 224 cooperate, so that the bottom plate connecting rod 222 drives the bottom plate 221 of the mold box to move upward, and the formed mixed The aerated concrete brick is pushed out of the inner wall of the mold box 219. When the formed aerated concrete brick rises to the top of the mold box 219 and is parallel to the top of the U-shaped plate 11 along with the bottom plate 221 of the mold box, the push plate 34 of the push mechanism 3 has moved to the leftmost side of the slide plate 31. At this time, the push plate 312 has also reached the limit of its travel. At the same time, the aerated concrete brick on the bottom plate 221 of the mold box has completely broken away from the constraint of the mold box 219 and is pushed to the top of the cutting table 5 by the push plate 312, and then the cutting device 6 is started.

[0043] Carry out subsequent processing operations.

[0044] like Figure 7-8As shown, the cover plate control mechanism 4 includes two cover plate transmission uprights 41, the bottoms of the two cover plate transmission uprights 41 are respectively fixedly connected to the front and rear sides of the top of the U-shaped plate 11, and the opposite sides of the two cover plate transmission uprights 41 are provided with transmission chutes 44. The inner walls of the second screw rods 45 opened by the two cover plate transmission uprights 41 are slidably connected with T-shaped transmission rods 46, and the bottom of the middle part of the T-shaped transmission rod 46 is fixedly connected with a cover plate 47, and the cover plate 47 is aligned with the top of the mold box 219. The top of the rear cover plate transmission upright 41 is fixedly connected with a motor placement block 42, and the inner wall of the motor placement block 42 is fixedly connected with a motor 43, and the output end of the motor 43 extends to the inner wall of the cover plate transmission upright 41. The cover plate 47 is fixedly connected with a second screw rod 45, the bottom of which is movably connected to the bottom of the inner wall of the transmission chute 44 provided on the rear cover plate transmission vertical plate 41, and the outer wall of the second screw rod 45 is threadedly connected to the rear inner wall of the T-shaped transmission rod 46. The cover plate 47 includes a cover plate body 471, and the front and rear sides of the bottom of the cover plate body 471 are respectively fixedly connected with bottom pressure plate chute rods 472, and the left and right sides of the inner walls of the two bottom pressure plate chute rods 472 are slidably connected with sliders 473, and the bottoms of the two groups of sliders 473 are rotatably connected with rotating rods 474, and the opposite surfaces of the two groups of rotating rods 474 are fixedly connected with springs 475, and the bottoms of the two groups of rotating rods 474 are rotatably connected with the bottom of the bottom cover plate 476;

[0045] When it is necessary to cover the top of the mold box 219, the motor 43 is started, and the output end of the motor 43 drives the second screw rod 45 to rotate. Since the T-shaped transmission rod 46 is threadedly connected to the second screw rod 45, the T-shaped transmission rod 46 moves downward along the conveying chute 44, thereby driving the cover plate 47 to move downward until the bottom of the cover plate 47 is completely in contact with the top of the mold box 219, thereby achieving the closure of the mold box 219;

[0046] During the process of the cover plate 47 descending, the bottom cover plate 476 first contacts the slurry in the mold box 219. While the cover plate 47 continues to descend, the bottom cover plate 476 rotates through the rotating rod 474 and slides to both sides on the inner wall of the bottom pressure plate slide rod 472 through the top slider 473. At this time, the spring 475 is deformed due to being squeezed, and the bottom of the bottom cover plate 476 is completely in contact with the surface of the slurry in the mold box 219 and continues to squeeze downward, thereby making the slurry surface smoother, ensuring the surface quality of the concrete aerated brick after molding. At the same time, the design of the bottom cover plate 476 can also effectively prevent the slurry from overflowing from the mold box 219 during the molding process.

[0047] In addition, the present invention also relates to a concrete aerated brick production device and a production method, comprising the following steps:

[0048] Step 1: Prepare the raw materials and stir them to ensure the uniformity and mixing effect of the raw materials, providing a high-quality slurry foundation for the subsequent molding process.

[0049] Step 2: Inject the stirred slurry into the mold box 219 to ensure that the slurry is filled evenly without bubbles or impurities.

[0050] Step 3: Start the cover plate control mechanism 4 and steadily cover the cover plate 47 on the top of the mold box 219 to ensure that the mold box 219 is completely closed so that the slurry can be stably formed in the mold box 219.

[0051] Step 4: Wait for the slurry to fully solidify in the mold box 219 to form the initial shape of the concrete aerated brick. During this process, the ambient temperature and humidity can be adjusted as needed to promote the solidification of the slurry.

[0052] Step 5: After the initial curing of the aerated concrete brick is completed, the dual-axis motor 36 and the pushing mechanism 3 are started, and the push plate 34 is pushed to move to the left through the transmission of the screw rod 39 and the transmission block 310. The push plate 34 pushes the push plate 312 to move to the left through the push plate push rod 311, thereby driving the mold box bottom plate 221 to move upward.

[0053] Step 6: As the mold box bottom plate 221 rises, the formed aerated concrete bricks are gradually pushed out of the mold box 219 and pushed to the top of the cutting table 5. During this process, the pushing plate 312 pushes the aerated concrete bricks smoothly to the designated position.

[0054] Step 7: After the aerated concrete bricks are pushed to the top of the cutting table 5, the cutting device 6 is started to cut and shape the aerated concrete bricks to meet different size and specification requirements.

[0055] Working principle of the present invention: After the raw materials of the aerated concrete brick are processed and stirred, slurry is formed and injected into the inner wall of the mold box 219, and then the cover plate control mechanism 4 is started to cover the cover plate 47 to the top of the mold box 219, and the slurry is formed on the inner wall of the mold box 219. After the forming is completed, the cover plate control mechanism 4 is started to lift the cover plate 47 off the top of the mold box 219, and then the double-axis motor 36 is started to make the conical gear 37 drive the second conical gear 38 to rotate, and then drive the screw rod 39 to rotate. As the screw rod 39 rotates, the transmission block 310 moves on the screw rod 39, pushing the push plate 34 to move left, and the push plate 34 pushes the push plate 312 to move left on the inner wall of the slide plate 31 through the push plate push rod 311. When the two transmission blocks 310 and the push plate 34 push the push plate 312 to move left on the inner wall of the slide plate 31, the two transmission blocks 310 drive the push-pull rod connecting rod 35 to move left, and the push-pull rod 35 moves left. The rod connecting rod 35 drives the two push-pull rods 226 to move leftward. The leftward movement of the push-pull rod 226 makes the slide rod 225 slide on the top inner wall of the slide slot plate 212, and then the inclined slide plate 223 cooperates with the inclined surface of the reverse inclined slide slot plate 224, so that the bottom plate connecting rod 222 drives the mold box bottom plate 221 to move upward, and pushes the formed concrete aerated brick out of the inner wall of the mold box 219. When the formed concrete aerated brick rises to the top of the mold box 219 and is parallel to the top of the U-shaped plate 11 along with the mold box bottom plate 221, the push plate 34 of the pushing mechanism 3 has moved to the leftmost side of the slide plate 31. At this time, the push plate 312 has also reached the limit of its travel. At the same time, the concrete aerated bricks on the mold box bottom plate 221 have completely broken away from the restraint of the mold box 219 and are pushed to the top of the cutting table 5 through the push plate 312, and then the cutting device 6 is started to perform subsequent processing operations.

[0056] When it is necessary to cover the top of the mold box 219, the motor 43 is started, and the output end of the motor 43 drives the second screw rod 45 to rotate. Since the T-shaped transmission rod 46 is threadedly connected to the second screw rod 45, the T-shaped transmission rod 46 moves downward along the conveying chute 44, thereby driving the cover plate 47 to move downward until the bottom of the cover plate 47 is completely in contact with the top of the mold box 219, thereby closing the mold box 219. During the descent of the cover plate 47, the bottom cover plate 476 first contacts the slurry in the mold box 219, and then the cover plate 47 is moved downward. While the bottom cover plate 476 continues to descend, it rotates through the rotating rod 474 and slides to both sides on the inner wall of the bottom pressure plate slide rod 472 through the top slider 473. At this time, the spring 475 is deformed due to being squeezed, and the bottom of the bottom cover plate 476 is completely in contact with the slurry surface in the mold box 219 and continues to squeeze downward, so that the slurry surface is smoother, ensuring the surface quality of the concrete aerated brick after molding. At the same time, the design of the bottom cover plate 476 can also effectively prevent the slurry from overflowing from the mold box 219 during the molding process.
