[0027] 1. In the present invention, by setting up a vibration linkage assembly, when the movable sealing plate flips, it drives the vibration pipe to drop through mechanical transmission for vibration. At the same time, the moving speed of the hopper is used to control the moving stroke of the counterweight ball, thereby changing the overall polarization distance of the vibration pipe, causing the vibration amplitude of the vibration pipe to change. Through the mechanical linkage design of the movable sealing plate and the vibration pipe, the synchronous action of the opening of the discharge pipe and the downward probing of the vibration pipe is achieved. When the movable cylinder drives the discharge pipe to open, the vibration pipe automatically penetrates into the mold for vibration compaction without the intervention of an additional control unit, significantly improving the automation level of the production line and production efficiency. The change in the moving speed of the hopper directly drives the change in the rotational speed of the transmission gear, and different centrifugal forces are generated by the rotating sleeve to drive the counterweight ball, realizing the adaptive adjustment of the eccentricity. When pouring at high speed, the amplitude is increased to ensure the density, and when at low speed, the amplitude is reduced to avoid excessive disturbance, enabling the vibration parameters to adapt to the process conditions in real time and improving the stability of the finished product quality.

[0028] 2. In the present invention, by setting up a leveling assembly, multiple electric push rods drive the leveling roller to be flush with the forming mold through the top plate. The driving motor cooperates with the reciprocating lead screw and the lead screw seat to move the leveling roller to one side, and the leveling roller rotates by itself, enabling the leveling roller to level the cement in the forming mold. The electric push rod adjusts the height of the top plate to accurately align the leveling roller with the mold; the reciprocating lead screw drives the leveling roller to move horizontally, combined with the self-rotation function, to achieve all-round leveling and avoid local unevenness. At the same time, through the coordinated action of the conveying roller, electric push rod, reciprocating lead screw, and driving gear, automatic leveling after cement pouring is realized, reducing manual intervention and improving production efficiency.

[0029] 3. In the present invention, by setting up a residual material collection assembly, when the travel block moves to the end of the travel groove, the lead screw seat drives the collection hopper to continue moving. The travel block drives the sliding bar to move in the hollow pipe and drives the collection hopper to flip through the fixed shaft, causing the residual material cement in the collection hopper to fall into the collection box. Through the synchronous movement design of the collection hopper and the leveling roller, combined with the closed collection-dumping process, it effectively prevents cement splashing, realizes the real-time dynamic collection of residual materials, avoids the shutdown problem caused by traditional intermittent cleaning, significantly improves the processing efficiency. At the same time, the precise control of the travel block, travel groove, sliding bar, and reciprocating lead screw automatically triggers the flipping action at the end of the movement to complete the dumping of residual materials, improving the automation level of this production line.

The fixed sliding rod 202 is connected to the fixed frame 1.

[0048] The implementation method is specifically as follows: By setting the vibration linkage component 2, when the movable sealing plate 214 flips, the vibration tube 203 is driven to fall for vibration through the mechanical transmission belt 507. At the same time, the moving speed of the hopper 3 is used to change the moving stroke of the counterweight ball 217, thereby changing the overall polarization distance of the vibration tube 203, making the vibration amplitude of the vibration tube 203 change. Through the mechanical linkage design of the movable sealing plate 214 and the vibration tube 203, the synchronous action of the opening of the discharge pipe 10 and the downward extension of the vibration tube 203 is realized. When the movable cylinder 211 drives the discharge pipe 10 to open, the vibration tube 203 automatically penetrates into the inside of the forming die for vibration compacting, without the intervention of an additional control unit, significantly improving the automation degree of the production line and the production efficiency. The change in the moving speed of the hopper 3 directly drives the change in the rotation speed of the transmission gear 206, and different centrifugal forces are generated on the counterweight ball 217 by driving the rotating sleeve 208, realizing the adaptive adjustment of the eccentricity. When pouring at high speed, the amplitude is increased to ensure the density, and when at low speed, the amplitude is reduced to avoid excessive disturbance, making the vibration parameters adapt to the process conditions in real time and improving the stability of the finished product quality.

A lead screw seat 505 is drivingly connected to the outer surface of the reciprocating lead screw 510. The bottom of the lead screw seat 505 is connected with two symmetrically arranged side plates. A leveling roller 504 for leveling cement is rotatably connected between the two side plates through a rotating shaft. Driving wheels 509 are rotatably connected to both sides of the lead screw seat 505. One end of the rotating shaft extends to the other side of the side plate and is connected with a driven wheel 506. A transmission belt 507 is drivingly connected between the driven wheel 506 and the driving wheel 509. A driving gear 508 is connected to one side of the driving wheel 509.

Two electric push rods 502 are connected to both sides of the bottom of the top plate 501. The other end of the electric push rod 502 is connected with a fixed support plate 6.

[0050] The implementation method is specifically as follows: By setting the leveling component 5, multiple electric push rods 502 drive the leveling roller 504 to be flush with the forming die through the top plate 501. The driving motor 503 cooperates with the reciprocating lead screw 510 and the lead screw seat 505 to move the leveling roller 504 to one side, and the leveling roller 504 rotates by itself, so that the leveling roller 504 levels the cement in the forming die. The electric push rod 502 adjusts the height of the top plate 501 to accurately align the leveling roller 504 with the die. The reciprocating lead screw 510 drives the leveling roller 504 to move horizontally. Combining with the self-rotation function, it realizes all-round leveling, avoiding local unevenness. At the same time, through the coordinated action of the conveying roller 8, the electric push rod 502, the reciprocating lead screw 510 and the driving gear 508, it realizes the automatic leveling after cement pouring, reduces manual intervention and improves production efficiency.

[0051] The surplus material collection component 9 includes a collection hopper 907 that can be flipped. The collection hopper 907 is attached to one side of the leveling roller 504. Two symmetrically arranged connecting seats 906 are connected to the top of the collection hopper 907. A fixed shaft 905 is connected inside the connecting seat 906. One side of the fixed shaft 905 is rotatably connected to a mounting seat, and the mounting seat is connected to one side of the lead screw seat 505. One end of the fixed shaft 905 is connected to a hollow tube 904. A sliding bar 903 is slidably connected inside the hollow tube 904.

Travel grooves 901 are opened at both ends of the top plate 501, and the travel block 902 is slidably connected inside the travel grooves 901.

[0052] The implementation method is specifically as follows: By setting the surplus material collection component 9, when the travel block 902 moves to the end of the travel groove 901, the lead screw seat 505 drives the collection hopper 907 to continue moving. The travel block 902 drives the sliding bar 903 to move inside the hollow tube 904, and drives the collection hopper 907 to flip through the fixed shaft 905, so that the surplus cement in the collection hopper 907 falls into the collection box 908. Through the synchronous movement design of the collection hopper 907 and the leveling roller 504, combined with the closed collection-dumping process, it effectively prevents cement splashing, realizes the real-time dynamic collection of surplus materials, avoids the shutdown problem caused by traditional intermittent cleaning, significantly improves the processing efficiency. At the same time, with the precise control of the travel block 902, the travel groove 901, the sliding bar 903 and the reciprocating lead screw 510, the flipping action is automatically triggered at the end of the movement to complete the dumping of surplus materials, improving the automation degree of this production line.

[0053] Working principle: During use, the staff conveys cement into the hopper 3 through an external feeding mechanism. The staff places the forming mold on the conveying roller 8 through external equipment. When the conveying roller 8 transports the forming mold to directly below the hopper 3, the conveying roller 8 stops rotating. The movable cylinder 211 drives the connecting frame 210 to move downward. The connecting frame 210 drives the connecting rod 212 to move downward. The connecting rod 212 drives the movable sealing plate 214 to expand outward through the rotating hinge frame 213, so that the discharge pipe 10 is opened. Cement enters the forming mold through the discharge pipe 10. Moreover, the linear module 4 drives the discharge pipe 10 to reciprocate through the hopper 3 and evenly pour into the forming mold. During this process, the movable cylinder 211 drives the vibration pipe 203 to penetrate into the forming mold through the connecting frame 210 and the fixed ring 204. Moreover, during the movement of the discharge pipe 10, it drives the transmission gear 206 to move on the fixed rack 201, so that the transmission gear 206 rotates self. The transmission gear 206 drives the rotating rod 207 to rotate. The rotating rod 207 drives the rotating sleeve 208 to rotate. The rotating sleeve 208 drives the deflection box 216 to rotate. Through the deflection rotation of the deflection box 216, the vibration pipe 203 vibrates. The vibration pipe 203 vibrates the cement poured into the forming mold, thereby reducing the air volume in the cement. And according to the change of the moving speed of the hopper 3, the rotation speed of the transmission gear 206 changes. The transmission gear 206 drives the rotation speed of the rotating sleeve 208 to change, so that the centrifugal force received by the counterweight ball 217 changes, thereby changing the eccentricity of the eccentric rotation inside the vibration pipe 203, and thus changing the amplitude of the vibration pipe 203.

[0054] After completing the pouring and vibrating compaction of the cement in the forming mold, the conveying roller 8 drives the forming mold to continue moving to the bottom of the top plate 501. The conveying roller 8 stops rotating. Multiple electric push rods 502 drive the top plate 501 to move downward and make the leveling roller 504 flush with the forming mold. The drive motor 503 drives the reciprocating lead screw 510 to rotate. The reciprocating lead screw 510 drives the lead screw seat 505 to move from one side to the other side. During this process, the drive gear 508 rotates self under the drive of the drive rack 511. The drive gear 508 drives the driving wheel 509 to rotate. The driving wheel 509 drives the driven wheel 506 to rotate through the transmission belt 507. The driven wheel 506 drives the leveling roller 504 to rotate, so that the leveling roller 504 levels the cement in the forming mold. After completing the leveling, the reciprocating lead screw 510 cooperates with the lead screw seat 505 to drive the leveling roller 504 to reset.

[0055] During the leveling process, when the leveling roller 504 levels the cement, excess cement will be rolled and splashed into the collection hopper 907. Moreover, the collection hopper 907 always moves with the leveling roller 504 to collect the surplus material. During this process, the travel block 902 moves within the travel groove 901. When the collection hopper 907 moves close to one side of the collection box 908, the travel block 902 moves to the end of the travel groove 901. At this time, the lead screw seat 505 drives the collection hopper 907 to continue moving. The travel block 902 drives the sliding bar 903 to move within the hollow tube 904 and drives the collection hopper 907 to flip through the fixed shaft 905, so that the surplus cement in the collection hopper 907 falls into the collection box 908, completing the collection of the excess cement.
