Technical Field

[0001] The invention relates to the technical field of laminated wallboard production equipment, and in particular to a laminating device for preparing laminated wallboards and a use method thereof. Background Art

[0002] With the development of civil construction, higher requirements are put forward for the diversification of architectural design. The plane size of the composite wall panel is flexible, which is convenient for opening holes on the wall panel. It can adapt to the requirements of building span, depth and opening, and has good building functions. The composite wall panel is an assembled integral wall panel composed of prefabricated panels and cast-in-place reinforced concrete layers. The composite floor slab has good integrity, high rigidity, and can save templates.

[0003] When the composite wall panels are pressed together, hydraulic cylinders are often used to push the pressing plates to squeeze the concrete in the mold. However, when the concrete is poured into the mold, it may be difficult to fully fill the mold, which may cause local depressions in the concrete. It is usually difficult to completely eliminate these depressions during the pressing process. The depressions will cause the composite wall panels to have an uneven structure and affect the quality of the composite wall panels. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a laminating device for preparing laminated wall panels, comprising a placing table, a wall panel mold is slidably connected to the top of the placing table, a fixed table is fixedly connected to the top of the placing table, a hydraulic cylinder is fixedly connected to the top of the fixed table, and a limit block is fixedly connected to the top of the placing table;

[0005] The pressing mechanism includes a laminated wallboard, an extrusion plate 1 for pressing the laminated wallboard, a pressing plate, a spring return rod 1, and a roller pressing assembly for pressing the laminated wallboard more evenly;

[0006] The outer wall of the composite wall panel is placed on the inner wall of the wall panel mold, the top of the extrusion plate 1 is fixedly connected to the bottom output end of the hydraulic cylinder, the number of spring return rods 1 is four, the top of the pressing plate is fixedly connected to the bottom of the four spring return rods 1, and the outer walls of the four spring return rods 1 are slidably connected to the inner wall of the extrusion plate 1. When in use, the staff pulls out the wall panel mold and pours concrete into the wall panel mold to initially form the composite wall panel. After the pouring is completed, the wall panel mold is pushed to contact the limit block to position the wall panel mold, and then The hydraulic cylinder is started to extend, pushing the extrusion plate 1 down, and synchronously driving the extrusion plate 2 down, and driving the pressing plate to descend through the spring return rod 1, to initially press the concrete in the wall panel mold, and then the electric telescopic rod is started to extend and retract reciprocally. When the electric telescopic rod is extended, it will push the fixed frame to move toward the oil storage frame, driving the roller to roll on the pressing plate, squeezing the pressing plate until the roller contacts the spring pressing plate, pushing the spring pressing plate to squeeze the hydraulic oil 1 in the oil storage frame, and the squeezed hydraulic oil 1 will mix with the hydraulic oil 2 in the oil pipeline The spring ball rod is combined, thereby pushing the spring ball rod to move and separate from the bevel ring, allowing the spring ball rod to accumulate resilience. Since the contact surface between the bevel ring and the spring ball rod is an inclined surface, a gap will leak out between the two after the spring ball rod moves, and the hydraulic oil 2 will push the piston rod down through the gap, thereby driving the extrusion plate to move down, causing the spring return rod 2 to accumulate resilience, allowing the fixed frame to move down, increasing the extrusion force of the roller on the pressing plate, at this time, the electric telescopic rod will retract, allowing the fixed frame to move to the left again, allowing the roller to separate from the spring pressure plate, and the resilience of the spring pressure plate will be released. Release, let the spring pressure plate return to its position, the extrusion pressure on hydraulic oil one disappears, the rebound force of the spring ball rod is released, let the spring ball rod return to its position, contact with the bevel ring again, block hydraulic oil two, prevent hydraulic oil two from flowing back, let the extrusion plate return to its position, ensure the stability of the increased extrusion force, first perform preliminary extrusion through the pressing plate, which can make the concrete initially formed in the wall panel mold, and when the roller rolls, the extrusion pressure is indirectly increased, so that the pressure is diffused inside the concrete, so that the concrete is gradually dispersed, and the dispersed concrete can fill its concave parts.

[0007] Preferably, the rolling assembly comprises an extrusion plate 2 arranged at the bottom of the extrusion plate 1, the top of the extrusion plate 2 is fixedly connected with two spring return rods 2, the outer walls of the two spring return rods 2 are slidably connected with the inner wall of the extrusion plate 1, and the side wall of the extrusion plate 2 is fixedly connected with an electric telescopic rod;

[0008] Among them, the bottom of the extrusion plate 2 is slidably connected to a fixing frame, the inner wall of the fixing frame is rotatably connected to a roller, and the side wall of the fixing frame is fixedly connected to the output end of the side wall of the electric telescopic rod.

[0009] Preferably, the rolling assembly further comprises an oil storage frame fixedly connected to one side wall of the extrusion plate, a spring pressure plate is slidably connected to the inner wall of the oil storage frame, hydraulic oil is arranged on the inner wall of the oil storage frame, and three oil delivery pipes are connected through the side wall of the oil storage frame;

[0011] Preferably, the rolling assembly further comprises a fixed sleeve fixedly connected to the inner wall of the oil pipeline, the inner walls of the three fixed sleeves are all slidably connected with spring round ball rods, the inner walls of the three oil pipelines are all slidably connected with piston rods, and the bottoms of the three piston rods are all fixedly connected to the top of the second extrusion plate;

[0012] Among them, a transverse rod is arranged on the top of the extrusion plate 2, and the side walls of the transverse rod are fixedly connected with the side walls of the three spring ball rods.

[0013] Preferably, the extrusion assembly includes a connecting frame arranged at the bottom of the extrusion plate 2, a concave-convex plate is fixedly connected to the inner wall of the extrusion plate 2, a spring return rod 3 is fixedly connected to the top of the connecting frame, and the outer wall of the spring return rod 3 is slidably connected to the inner wall of the fixed frame;

[0014] Among them, the top of the spring return rod three is slidably connected to the bottom of the concave-convex plate, and two extrusion plates three are slidably connected to the inner wall of the extrusion plate two. The tops of the two extrusion plates three are rotatably connected with connecting rods. When the fixed frame moves, it will also drive the connecting frame to move, allowing the spring return rod three to slide at the bottom of the concave-convex plate. When the spring return rod three contacts the convex point of the concave-convex plate, the spring return rod three will be squeezed and moved down, causing the connecting frame to move down. When the spring return rod three contacts the concave position of the concave-convex plate again, the rebound force of the spring return rod three will be released, causing the connecting frame to rise, until the spring return rod three contacts the convex point of the concave-convex plate again, and the connecting frame will move down again, and so on.

[0015] Preferably, the extrusion assembly further comprises a spring rod fixedly connected to the inner wall of the extrusion plate, two sliding frames are arranged on the top of the pressing plate, the inner walls of the two sliding frames are slidably connected to the outer wall of the spring rod, and the inner walls of the two sliding frames are rotatably connected to three rollers;

[0016] Among them, the tops of the two sliding frames are rotatably connected with roller two, and two inclined blocks are fixedly connected to the side walls of the fixed frame. The bottoms of the connecting frames are slidably connected to the inner walls of the two connecting rods. A pushing component is provided at the bottom of the connecting frame. When the connecting frame descends, it will push the connecting rod to rotate, so that the connecting rod pushes the extrusion plate three to move toward the direction of the pressing plate until the extrusion plate three contacts the wall panel mold and squeezes both sides of the wall panel mold. At the same time, the movement of the extrusion plate three will also drive the sliding frame to move, so that the roller two contacts the inclined surface of the inclined block, so that the roller two is squeezed and descends, driving the sliding frame to descend, and squeezing the spring rod. The descent of the sliding frame will make the roller one contact with the pressing plate, and the extrusion plate three continues to move, and the extrusion force between the roller one and the pressing plate will increase, so that during the movement of the roller one, the two sides of the pressing plate are laterally squeezed.

[0017] Preferably, the pushing assembly comprises two fixed rings fixedly connected to the side walls of the fixed frame, two rotating rings are rotatably connected to the inner wall of the connecting frame, the top of the rotating ring is rotatably connected to a universal rod, and the inner wall of the fixed ring is rotatably connected to the top of the universal rod;

[0018] Among them, a counterweight block is fixedly connected to the bottom of the rotating ring, and a threaded rod is fixedly connected to the bottom of the rotating ring. When the connecting frame descends, the rotating ring will also be driven to descend, so that the distance between the rotating ring and the fixed ring will increase, and the universal rod will rotate on the fixed ring and the rotating ring. After the distance between the two increases, the ball on the universal rod on the rotating ring will approach the ball on the fixed ring, thereby pushing the rotating ring to rotate.

[0019] Preferably, the pushing assembly further comprises two spring extrusion blocks slidably connected to the inner wall of the connecting frame, a threaded ring is threadedly connected to the outer wall of the threaded rod, and the bottoms of the two spring extrusion blocks are fixedly connected to a pressing plate;

[0020] Among them, the tops of the two spring extrusion blocks are fixedly connected to the bottoms of the two threaded rings, and an injection assembly is arranged on the top of the pressing plate. Since a counterweight block is installed on the left side of the rotating ring, the gravity generated by the counterweight block will generate a torque on the rotating ring, and the rotating ring will rotate toward the direction of the counterweight block, so that the rotating ring will rotate counterclockwise, driving the threaded rod to rotate, causing the threaded ring to descend, pushing the spring extrusion block to descend, and at the same time, when the connecting frame descends, it will also drive the spring extrusion block to descend, causing the spring extrusion block to squeeze the pressing plate and contact the pressing plate, thereby squeezing the pressing plate and cooperating with the rotation of the rotating ring to allow the spring extrusion block to descend a longer distance.

[0021] Preferably, the jet assembly includes an air collecting frame fixedly connected to the right side of the fixing frame, a push plate is slidably connected to the inner wall of the air collecting frame, eight air holes are opened on the inner wall of the air collecting frame, two connecting rods are fixedly connected to the side wall of the push plate, and the outer walls of the two connecting rods are slidably connected to the side walls of the two rotating rings;

[0022] Among them, a guide plate is fixedly connected to the side wall of the air collecting frame, and a spring blocking plate is rotatably connected to the inner wall of the guide plate. When the rotating ring rotates counterclockwise, it will drive the connecting rod to move toward the drum, thereby moving the pushing plate. When the pushing plate moves and covers the air hole, the pushing plate continues to move, which will squeeze the gas in the air collecting frame. At this time, the squeezed gas will be blocked by the spring blocking plate, so the gas pressure will increase.

[0023] A method for using a pressing device for preparing a composite wallboard comprises the following steps:

[0024] S1: Model casting: The staff pulls out the wall panel mold and pours concrete into the wall panel mold to initially shape the composite wall panel;

[0025] S2: Wall panel pressing: After pouring is completed, the wall panel mold is pushed to contact the limit block to position the wall panel mold, and then the hydraulic cylinder is started to extend, pushing the extrusion plate down, and the pressing plate is driven down by the spring return rod to perform preliminary pressing on the concrete in the wall panel mold.

[0026] The present invention has the following beneficial effects:

[0027] (1) When the present invention is used, the staff pulls out the wall panel mold and pours concrete into the wall panel mold to initially form the composite wall panel. After the pouring is completed, the wall panel mold is pushed to contact the limit block to position the wall panel mold, and then the hydraulic cylinder is started to extend, pushing the extrusion plate 1 down, and synchronously driving the extrusion plate 2 to descend, and driving the pressing plate to descend through the spring return rod 1 to initially press the concrete in the wall panel mold. Then, the electric telescopic rod is started to extend and retract reciprocally. When the electric telescopic rod is extended, it will push the fixed frame to move toward the oil storage frame, driving the roller to roll on the pressing plate to press the pressing plate until the roller contacts the spring pressing plate, pushing the spring pressing plate to squeeze the hydraulic oil 1 in the oil storage frame. The squeezed hydraulic oil 1 will mix with the hydraulic oil 2 in the oil pipeline, thereby pushing the spring ball rod to move and separate from the inclined ring, allowing the spring ball rod to accumulate resilience. Since the contact surface between the inclined ring and the spring ball rod is an inclined surface, After the spring ball rod moves, a gap will leak out between the two, and hydraulic oil 2 will push the piston rod down through the gap, thereby driving the extrusion plate 2 to drop, causing the spring return rod 2 to accumulate rebound force, allowing the fixed frame to drop, and increasing the extrusion pressure of the roller on the pressing plate. At this time, the electric telescopic rod will retract, allowing the fixed frame to move to the left again, allowing the roller to separate from the spring pressure plate, and the rebound force of the spring pressure plate will be released, allowing the spring pressure plate to return to its position, and the extrusion pressure on hydraulic oil 1 will disappear. The rebound force of the spring ball rod will be released, allowing the spring ball rod to return to its position and contact the bevel ring again to block hydraulic oil 2 and prevent hydraulic oil 2 from flowing back, allowing extrusion plate 2 to return to its position, ensuring the stability of the increased extrusion pressure. First, preliminary extrusion is carried out through the pressing plate, which can make the concrete initially formed in the wall panel mold. When the roller rolls, the extrusion pressure is indirectly increased, causing the pressure to diffuse inside the concrete, thereby allowing the concrete to gradually disperse, and the dispersed concrete can fill its concave parts.

[0028] (2) When the fixing frame moves, the present invention also drives the connecting frame to move, allowing the spring return rod three to slide at the bottom of the concave-convex plate. When the spring return rod three contacts the convex point of the concave-convex plate, the spring return rod three will be squeezed and lowered, causing the connecting frame to lower. When the spring return rod three contacts the concave position of the concave-convex plate again, the resilience of the spring return rod three will be released, causing the connecting frame to rise until the spring return rod three contacts the convex point of the concave-convex plate again, and the connecting frame will lower again. This reciprocating process will push the connecting rod to rotate when the connecting frame is lowered, causing the connecting rod to push the extrusion plate three to move toward the direction of the pressing plate until the extrusion plate three contacts the wall panel mold, thereby squeezing both sides of the wall panel mold. At the same time, the movement of the extrusion plate three will also drive the sliding frame to move, causing the roller two to contact the inclined surface of the inclined surface block, thereby causing the roller two to be squeezed. When the roller moves back and forth, the roller will exert a smaller pressure on the edge of the pressing plate, which may cause the concrete to spread to the two sides of the wall panel mold. The extrusion plate three squeezes the two sides of the wall panel mold, which can laterally constrain the concrete in the wall panel mold. The lateral extrusion of the two sides of the pressing plate by the roller pair can further limit the lateral movement of the concrete, effectively preventing the concrete from excessively spreading to the two sides of the wall panel mold.

[0029] (3) When the connecting frame of the present invention descends, it also drives the rotating ring to descend, so that the distance between the rotating ring and the fixed ring increases, and the universal rod rotates on the fixed ring and the rotating ring. After the distance between the two increases, the ball of the universal rod on the rotating ring will approach the ball on the fixed ring, thereby driving the rotating ring to rotate. Since a counterweight block is installed on the left side of the rotating ring, the gravity generated by the counterweight block will generate a torque on the rotating ring, and the rotating ring will rotate in the direction of the counterweight block, thereby causing the rotating ring to rotate counterclockwise, driving the threaded rod to rotate. The threaded ring is lowered to push the spring extrusion block down. At the same time, when the connecting frame is lowered, the spring extrusion block is also driven to lower, so that the spring extrusion block can squeeze the pressing plate and contact with the pressing plate to squeeze the pressing plate. The rotating ring is rotated to make the spring extrusion block descend a longer distance, thereby enhancing the extrusion force of the pressing plate and pre-tightening both sides of the pressing plate. The concrete on both sides of the pressing plate becomes tighter than other parts under the pressure generated by the pre-extrusion, thereby reducing the flow of concrete to both sides when the roller squeezes the pressing plate later.

[0030] (4) When the rotating ring of the present invention rotates counterclockwise, it will drive the connecting rod to move toward the roller, thereby moving the push plate. When the push plate moves and covers the air hole, the push plate continues to move and squeezes the gas in the gas collecting frame. At this time, the squeezed gas will be blocked by the spring blocking plate, so the gas pressure will increase. As the push plate continues to move, the protruding position of the push plate will contact the spring blocking plate, thereby pushing the spring blocking plate to rotate, so that the spring blocking plate accumulates rebound force. After the spring blocking plate rotates, a gap will leak out between the spring blocking plate and the guide plate. The gas will spray out from the gap through the guide plate toward the contact surface between the roller and the pressing plate, thereby reducing its temperature and effectively preventing the gradually increasing extrusion pressure between the roller and the pressing plate, which will increase the friction between the two and increase their temperature, affecting the stability of the roller extrusion.

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] For example, see Figure 1 - Figure 6 The present invention is a laminating device for preparing a laminated wallboard, comprising a placing table 1, a wallboard mold 11 is slidably connected to the top of the placing table 1, a fixing table 13 is fixedly connected to the top of the placing table 1, a hydraulic cylinder 14 is fixedly connected to the top of the fixing table 13, and a limiting block 12 is fixedly connected to the top of the placing table 1;

[0047] The pressing mechanism 2 includes a laminated wall panel 21, a pressing plate 22 for pressing the laminated wall panel 21, a pressing plate 23, a spring return rod 24, and a rolling assembly 3 for pressing the laminated wall panel 21 more evenly;

[0048] The outer wall of the composite wall panel 21 is placed on the inner wall of the wall panel mold 11, the top of the extrusion plate 22 is fixedly connected to the bottom output end of the hydraulic cylinder 14, the number of the spring return rods 24 is four, the top of the pressing plate 23 is fixedly connected to the bottom of the four spring return rods 24, and the outer walls of the four spring return rods 24 are slidably connected to the inner wall of the extrusion plate 22. When in use, the staff pulls out the wall panel mold 11, pours concrete into the wall panel mold 11, and makes the composite wall panel 21 initially formed. After the pouring is completed, the wall panel mold 11 is pushed to contact the limit block 12 to position the wall panel mold 11, and then the hydraulic The cylinder 14 extends out, pushing the extrusion plate 1 22 down, and synchronously driving the extrusion plate 2 31 down, driving the pressing plate 23 down through the spring return rod 1 24, and performing preliminary pressing on the concrete in the wall panel mold 11, and then starting the electric telescopic rod 32 to extend and retract reciprocally. When the electric telescopic rod 32 extends out, it will push the fixed frame 33 to move toward the oil storage frame 35, driving the roller 34 to roll on the pressing plate 23, and pressing the pressing plate 23 until the roller 34 contacts the spring pressure plate 351, pushing the spring pressure plate 351 to squeeze the hydraulic oil 1 in the oil storage frame 35, and the squeezed hydraulic oil 1 will contact the hydraulic oil 2 in the oil pipe 36 The mixture pushes the spring ball rod 363 to move and separate from the bevel ring 361, allowing the spring ball rod 363 to accumulate resilience. Since the contact surface between the bevel ring 361 and the spring ball rod 363 is an inclined surface, a gap will leak out between the two after the spring ball rod 363 moves, and the hydraulic oil 2 will push the piston rod 364 down through the gap, thereby driving the extrusion plate 21 to move down, so that the spring return rod 211 accumulates resilience, allowing the fixed frame 33 to move down, increasing the extrusion pressure of the roller 34 on the pressing plate 23. At this time, the electric telescopic rod 32 will retract, allowing the fixed frame 33 to move to the left again, allowing the roller 34 to separate from the spring pressure plate 351. The resilience of the spring pressure plate 351 will be released, allowing the spring pressure plate 351 to return to its original position, and the extrusion pressure on the hydraulic oil one will disappear. The resilience of the spring spherical rod 363 will be released, allowing the spring spherical rod 363 to return to its original position and contact the bevel ring 361 again to block the hydraulic oil two and prevent the hydraulic oil two from flowing back, allowing the extrusion plate 2 31 to return to its original position, thereby ensuring the stability of the increased extrusion pressure. The initial extrusion is first performed through the pressing plate 23, so that the concrete can be initially formed in the wall panel mold 11. When the roller 34 rolls, the extrusion pressure is indirectly increased, so that the pressure is diffused inside the concrete, thereby allowing the concrete to gradually disperse, and the dispersed concrete can fill its concave parts.

The extrusion plate 3 43 moves and the sliding frame 45 moves, so that the roller 2 47 contacts the inclined surface of the inclined surface block 48, thereby the roller 2 47 is squeezed and moved down, driving the sliding frame 45 to move down, squeezing the spring rod 44, and the sliding frame 45 descends to make the roller 1 46 contact the pressing plate 23. The extrusion plate 3 43 continues to move, and the extrusion force between the roller 1 46 and the pressing plate 23 increases, so that the roller 1 46 moves and the two sides of the pressing plate 23 are laterally squeezed.

[0059] The pushing assembly 5 includes two fixed rings 51 fixedly connected to the side walls of the fixed frame 33, two rotating rings 52 are rotatably connected to the inner wall of the connecting frame 41, the top of the rotating ring 52 is rotatably connected to the universal rod 53, and the inner wall of the fixed ring 51 is rotatably connected to the top of the universal rod 53;

[0060] Among them, a counterweight block 521 is fixedly connected to the bottom of the rotating ring 52, and a threaded rod 54 is fixedly connected to the bottom of the rotating ring 52. When the connecting frame 41 descends, the rotating ring 52 will also be driven to descend, so that the distance between the rotating ring 52 and the fixed ring 51 increases, and the universal rod 53 will rotate on the fixed ring 51 and the rotating ring 52. After the distance between the two increases, the ball on the universal rod 53 on the rotating ring 52 will approach the ball on the fixed ring 51, thereby pushing the rotating ring 52 to rotate.

[0061] The pushing assembly 5 further includes two spring extrusion blocks 56 slidably connected to the inner wall of the connecting frame 41, a threaded ring 55 is threadedly connected to the outer wall of the threaded rod 54, and a pressing plate 57 is fixedly connected to the bottom of the two spring extrusion blocks 56;

[0062] Among them, the tops of the two spring extrusion blocks 56 are fixedly connected to the bottoms of the two threaded rings 55, and the top of the pressing plate 23 is provided with an injection assembly 6. Since a counterweight block 521 is installed on the left side of the rotating ring 52, the gravity generated by the counterweight block will generate a torque on the rotating ring 52, and the rotating ring 52 will rotate in the direction of the counterweight block 521, so that the rotating ring 52 rotates counterclockwise, driving the threaded rod 54 to rotate, allowing the threaded ring 55 to descend, and pushing the spring extrusion block 56 to descend. At the same time, when the connecting frame 41 descends, it will also drive the spring extrusion block 56 to descend, and the spring extrusion block 56 will squeeze the pressing plate 57 to contact the pressing plate 23, squeeze the pressing plate 23, and cooperate with the rotation of the rotating ring 52 to make the spring extrusion block 56 descend a longer distance.

[0063] The jet assembly 6 includes an air collecting frame 61 fixedly connected to the right side of the fixing frame 33, a push plate 62 is slidably connected to the inner wall of the air collecting frame 61, eight air holes 611 are opened on the inner wall of the air collecting frame 61, two connecting rods 63 are fixedly connected to the side wall of the push plate 62, and the outer walls of the two connecting rods 63 are slidably connected to the side walls of the two rotating rings 52;

[0064] Among them, a guide plate 64 is fixedly connected to the side wall of the air collecting frame 61, and a spring blocking plate 65 is rotatably connected to the inner wall of the guide plate 64. When the rotating ring 52 rotates counterclockwise, it will drive the connecting rod 63 to move toward the roller 34, thereby moving the push plate 62. When the push plate 62 moves and covers the air hole 611, the push plate 62 continues to move, which will squeeze the gas in the air collecting frame 61. At this time, the squeezed gas will be blocked by the spring blocking plate 65, so the gas pressure will increase.

[0065] There is no limitation on the number of the above components, and relevant technicians in the field can freely set them according to actual needs, as long as the above components are installed at the connection positions of the corresponding components.

[0066] The method for using the laminating device for preparing the laminated wallboard comprises the following steps:

[0067] S1: Model casting: The staff pulls out the wall panel mold 11 and pours concrete into the wall panel mold 11 to initially shape the composite wall panel 21;

[0068] S2: Wall panel pressing: After pouring is completed, the wall panel mold 11 is pushed to contact the limit block 12 to position the wall panel mold 11, and then the hydraulic cylinder 14 is started to extend, pushing the extrusion plate 22 down, and the pressing plate 23 is driven down by the spring return rod 24 to perform preliminary pressing on the concrete in the wall panel mold 11.

[0069] A specific application of this embodiment is as follows: when the present invention is used, the staff pulls out the wall panel mold 11, pours concrete into the wall panel mold 11, and preliminarily forms the composite wall panel 21. After the pouring is completed, the wall panel mold 11 is pushed to contact the limit block 12 to position the wall panel mold 11, and then the hydraulic cylinder 14 is started to extend, pushing the extrusion plate 1 22 down, and synchronously driving the extrusion plate 2 31 down, and driving the pressing plate 23 down through the spring return rod 1 24, and preliminarily pressing the concrete in the wall panel mold 11, and then starting the electric telescopic rod 32 The electric telescopic rod 32 extends and retracts reciprocatingly. When the electric telescopic rod 32 extends, it pushes the fixing frame 33 to move toward the oil storage frame 35, driving the roller 34 to roll on the pressing plate 23 to squeeze the pressing plate 23 until the roller 34 contacts the spring pressing plate 351, pushing the spring pressing plate 351 to squeeze the hydraulic oil 1 in the oil storage frame 35. The squeezed hydraulic oil 1 will mix with the hydraulic oil 2 in the oil delivery pipe 36, thereby pushing the spring ball rod 363 to move and separate from the bevel ring 361, allowing the spring ball rod 363 to accumulate resilience. The contact surface of the ball rod 363 is an inclined surface. After the spring ball rod 363 moves, a gap will leak out between the two, and the hydraulic oil 2 will push the piston rod 364 down through the gap, thereby driving the extrusion plate 21 to descend, so that the spring return rod 211 accumulates resilience, allowing the fixed frame 33 to descend, increasing the extrusion force of the roller 34 on the pressing plate 23. At this time, the electric telescopic rod 32 will retract, allowing the fixed frame 33 to move to the left again, allowing the roller 34 to separate from the spring pressure plate 351, and the resilience of the spring pressure plate 351 will be released, allowing the spring pressure plate 351 to return to its original position. The squeezing force of the hydraulic oil 1 disappears, and the resilience of the spring ball rod 363 is released, so that the spring ball rod 363 returns to its original position and contacts the bevel ring 361 again, thereby blocking the hydraulic oil 2 and preventing the hydraulic oil 2 from flowing back. The squeezing plate 21 returns to its original position, thereby ensuring the stability of the increased squeezing force. The concrete is initially squeezed by the pressing plate 23, so that the concrete can be initially formed in the wall panel mold 11. When the roller 34 rolls, the squeezing force is indirectly increased, so that the pressure is diffused inside the concrete, thereby gradually dispersing the concrete, and the dispersed concrete can fill the concave part.

[0070] When the pressing is completed, the electric telescopic rod 32 drives the fixed frame 33 to return to its original position, and then the electric telescopic rod 32 is retracted again, driving the fixed frame 33 to contact the transverse rod 37, thereby driving the transverse rod 37 to move, and the transverse rod 37 pulls the spring ball rod 363 to move, and a gap is formed between the spring ball rod 363 and the bevel ring 361, so that the hydraulic oil can enter the oil storage frame 35 through the gap, and the rebound force of the spring return rod 311 will be released, so that the extrusion plate 21 returns to its original position, and then the extrusion plate 22 brought by the retracted hydraulic cylinder 14 and the pressing plate 23 rise and separate from the wall panel mold 11, so that the wall panel mold 11 can be pulled out, the mold can be replaced, and the next laminated wall panel 21 can be pressed;

[0071] Secondly, when the fixing frame 33 moves, the connecting frame 41 is also driven to move, so that the spring return rod 3 411 slides on the bottom of the concave-convex plate 42. When the spring return rod 3 411 contacts the convex point of the concave-convex plate 42, the spring return rod 3 411 is squeezed and moves down, causing the connecting frame 41 to move down. When the spring return rod 3 411 contacts the concave position of the concave-convex plate 42 again, the resilience of the spring return rod 3 411 is released, causing the connecting frame 41 to move up, until the spring return rod 3 411 is pushed down. 11 contacts the convex point of the concave-convex plate 42 again, and the connecting frame 41 will descend again, and so on. When the connecting frame 41 descends, it will push the connecting rod 431 to rotate, so that the connecting rod 431 pushes the extrusion plate 3 43 to move toward the pressing plate 23, until the extrusion plate 3 43 contacts the wall panel mold 11, and squeezes both sides of the wall panel mold 11. At the same time, the movement of the extrusion plate 3 43 will also drive the sliding frame 45 to move, so that the roller 2 47 contacts the inclined surface of the inclined surface block 48, so that the roller The second 47 is squeezed and descends, driving the sliding frame 45 to descend and squeeze the spring rod 44. The descent of the sliding frame 45 will make the roller 1 46 contact with the pressing plate 23. The squeezing plate 3 43 continues to move, and the squeezing force between the roller 1 46 and the pressing plate 23 will increase. During the movement of the roller 1 46, the two sides of the pressing plate 23 are laterally squeezed, and the front and back sides of the mold are squeezed by the squeezing plate 3 43. At the same time, the roller 1 46 squeezes the pressing plate 23 laterally, effectively preventing the roller 34 from rolling back and forth. The squeezing force of the roller 34 on the edge of the pressing plate 23 is small, which may cause the concrete to spread to the two sides of the wall panel mold 11. The squeezing plate 3 43 squeezes the two sides of the wall panel mold 11, which can laterally constrain the concrete in the wall panel mold 11. The lateral squeezing of the two sides of the pressing plate 23 by the roller 1 46 can further limit the lateral movement of the concrete, effectively preventing the concrete from excessively spreading to the two sides of the wall panel mold 11.

[0072] Secondly, when the connecting frame 41 descends, it will also drive the rotating ring 52 to descend, so that the distance between the rotating ring 52 and the fixed ring 51 increases, and the universal rod 53 will rotate on the fixed ring 51 and the rotating ring 52. After the distance between the two increases, the ball of the universal rod 53 on the rotating ring 52 will approach the ball on the fixed ring 51, thereby pushing the rotating ring 52 to rotate. Since a counterweight block 521 is installed on the left side of the rotating ring 52, the gravity generated by the counterweight block will generate a torque on the rotating ring 52, and the rotating ring 52 will rotate in the direction of the counterweight block 521, so that the rotating ring 52 rotates counterclockwise, driving the threaded rod 54 to rotate. The spring extrusion block 56 is moved to move, so that the threaded ring 55 descends, and pushes the spring extrusion block 56 to descend. At the same time, when the connecting frame 41 descends, the spring extrusion block 56 is also driven to descend, so that the spring extrusion block 56 squeezes the pressing plate 57 to contact with the pressing plate 23, and squeezes the pressing plate 23. With the rotation of the rotating ring 52, the spring extrusion block 56 is allowed to descend a longer distance, thereby enhancing the extrusion force of the pressing plate 57, and pre-pressing the two sides of the pressing plate 23. The concrete on both sides of the pressing plate 23 becomes more compact under the pressure generated by the pre-extrusion than other parts, and the flow of concrete to both sides is reduced when the roller 34 squeezes the pressing plate 23 later.

[0073] Secondly, when the rotating ring 52 rotates counterclockwise, it will drive the connecting rod 63 to move toward the roller 34, so that the pushing plate 62 moves. When the pushing plate 62 moves and covers the air hole 611, the pushing plate 62 continues to move, which will squeeze the gas in the gas collecting frame 61. At this time, the squeezed gas will be blocked by the spring blocking plate 65, so the pressure of the gas will increase. As the pushing plate 62 continues to move, the protruding position of the pushing plate 62 will contact the spring blocking plate 65, thereby pushing the spring blocking plate 65 to rotate, so that the spring blocking plate 65 accumulates a rebound force. After the spring blocking plate 65 rotates, a gap will leak out between the guide plate 64, and the gas will be ejected from the gap through the guide plate 64 toward the contact surface between the roller 34 and the pressing plate 23, so that its temperature is reduced, and the extrusion pressure between the roller 34 and the pressing plate 23 is effectively prevented from gradually increasing, resulting in an increase in the friction between the two, which increases their temperature and affects the stability of the extrusion of the roller 34.

[0074] When the connecting frame 41 returns, the rotating ring 52 will rotate clockwise to drive the connecting rod 63 to return, thereby allowing the pushing plate 62 to return. After the pushing plate 62 returns, the gas in the gas collecting frame 61 will be replenished through the air hole 611.
