Description

Technical Field

[0001] This invention relates to the field of energy-saving building material production equipment technology, specifically to an automated continuous production equipment for prefabricated thermal insulation and soundproofing panels. Background Technology

[0002] As people's requirements for living environments increase, so do their demands for the thermal insulation and sound insulation functions of precast slabs, leading to the widespread use of thermal insulation and sound insulation panels. The sound insulation and thermal insulation functions of floor slabs are receiving increasing attention in building design. Generally, precast slabs (assembled modules) are laid on the floor first, facilitating the later installation of wooden planks or tiles for finishing. During the manufacturing process of thermal insulation and sound insulation panels, semi-liquid gypsum or cement slurry is typically injected into molds, and a chain conveyor is used to circulate the molds, thus completing the injection and demolding process.

[0003] Currently, prefabricated thermal insulation and sound insulation panels, as one of the core materials for energy-saving buildings, still rely on traditional semi-automated or manual-assisted production methods, which presents the following problems: When injecting cement slurry into the mold, existing production equipment mostly adjusts the injection volume by manually controlling valve opening and closing or by simple timing, lacking a precise quantitative material distribution structure; the functional panels (such as polystyrene foam boards, rock wool insulation boards, etc.) in the thermal insulation and sound insulation panels need to be placed manually, and manual operation may cause the functional panels to be placed at an angle, affecting the bonding strength between the functional panels and the slurry, and the labor cost is high; traditional panel placement machines lack the function of subsequent leveling and inspection of functional panels, and manual inspection is still required for each panel placement.

[0004] For example, patent CN119188958A discloses a production device and method for modular thermal insulation and soundproofing panels for floors and ground. This device includes a chain conveyor, multiple flexible molds, and a hopper. The chain conveyor drives the multiple flexible molds sequentially under the hopper. The chain conveyor is equipped with a baffle device, which includes a first connecting frame, a baffle hopper, and a first drive cylinder. The first drive cylinder switches the baffle hopper between a baffle position and a discharge position. This invention ensures that the slurry does not flow onto the molds or into the gaps between the molds while the hopper continuously discharges material. By setting up the chain conveyor, flexible molds, and flattening components, automatic demolding is achieved, reducing production costs and improving production efficiency. However, this production device relies on manual labor to place each functional layer and mesh fabric into the slurry of the flexible molds one by one during the production of thermal insulation and soundproofing panels. Furthermore, manual pre-flattening of each functional layer placed in the slurry layer is performed multiple times, resulting in high labor costs, low automation, and the risk of tilting due to manual pressing. Therefore, the present invention provides an automated continuous production equipment for prefabricated thermal insulation and sound insulation panels to achieve more comprehensive automated continuous production. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the above-mentioned background technology and to provide an automated continuous production equipment for assembled thermal insulation and sound insulation panels.

[0006] The present invention achieves the above-mentioned objectives through the following technical solution: an automated continuous production equipment for prefabricated thermal insulation and soundproofing panels, comprising a chain conveyor, a plurality of flexible molds spaced apart on the chain conveyor, and a hopper for injecting slurry into the flexible molds. The chain conveyor drives the plurality of flexible molds to sequentially circulate below the hopper. The hopper is equipped with an equal-volume dispensing component to inject an equal amount of slurry into each of the flexible molds. An automatic plate-laying mechanism is provided across the top of the chain conveyor housing, spanning the flexible molds. As the chain conveyor moves, the automatic plate-laying mechanism places functional plates into each of the flexible molds that have been injected with slurry. A leveling and detection mechanism is provided downstream of the automatic plate-laying mechanism to perform at least one pre-leveling and position detection on the functional plates in each of the flexible molds.

[0007] Furthermore, the equal-volume material distribution assembly includes a cylindrical material cavity disposed at the bottom of the injection hopper, a cross-shaped material distribution plate rotatably installed inside the material cavity, the material distribution plate will come into close contact with the arc surfaces on both sides of the material cavity when rotating to form a sealed cavity, the sealed cavity containing a quantitative amount of slurry injected into the soft mold; a geared motor is installed on the outer side of the injection hopper, the output end of the geared motor is connected to the rotating shaft of the material distribution plate.

[0008] Furthermore, the automatic plate-laying mechanism includes a plate-laying frame, in which multiple functional plates are stacked. Plate-laying assemblies are provided on both sides of the plate-laying frame. Each plate-laying assembly includes a connecting plate connected to the bottom of the plate-laying frame. A fixing plate is provided on one side of the connecting plate and perpendicularly connected to the side of the plate-laying frame. A first gear and a second gear meshing with each other are rotatably provided on the side of the fixing plate. A second cylinder is hinged to the connecting plate. The output end of the second cylinder is connected to the central shaft of the first gear through a connecting rod. A baffle and a plate-laying plate are respectively fixedly connected to the ends of the central shafts of the first gear and the second gear.

[0009] Furthermore, the leveling and detection mechanism includes an adjusting plate, a main connecting rod hinged at the middle section of the side of the adjusting plate, and two auxiliary connecting rods hinged at the tail section of the side of the adjusting plate. An installation cavity is opened inside the housing of the chain conveyor. A third gear is rotatably mounted on the side surface of the installation cavity. A rack is connected to one side of the third gear via a transmission connection. A third cylinder is located on one side of the rack, and the output end of the third cylinder is connected to the rack. The other end of the main connecting rod is connected to the central shaft of the third gear. The other ends of the two auxiliary connecting rods are both hinged to the side surface of the installation cavity. Detection sensors are provided at both ends of the bottom surface of the adjusting plate, and sensing points corresponding to the detection sensors are installed on the blocks between two adjacent soft molds.

[0010] Furthermore, both the main connecting rod and the auxiliary connecting rod are electric push rods to adjust the lateral distance of the adjusting plate when it is pressed up and down twice in the direction of movement of the soft mold. This allows the leveling and detection mechanism to perform two leveling operations on the same functional plate at the front and back.

[0011] Furthermore, the production equipment also includes a flattening assembly for flattening the blank on the soft mold. The flattening assembly includes a first drive wheel, a first driven wheel corresponding to the first drive wheel, and a belt arranged in an annular shape between the first drive wheel and the first driven wheel. When the soft mold passes through the flattening assembly driven by the chain conveyor, the belt presses on the blank. The flattening assembly also includes a first bracket connected to both the first drive wheel and the first driven wheel. The first bracket is also equipped with a plurality of support wheels for supporting the belt.

[0012] Furthermore, the first support is connected to a height adjustment component for adjusting the height of the flattening component. The height adjustment component includes a protruding plate fixedly connected to the side of the first support. A hydraulic cylinder is installed on the outer side of the chain conveyor housing at a position corresponding to the protruding plate, and the output end of the hydraulic cylinder is connected to the protruding plate.

[0013] Furthermore, the chain conveyor is provided with a mounting frame on the feeding side, and a first cylinder is mounted on the mounting frame. One end of the telescopic rod of the first cylinder is connected to a sealing plate for sealing the discharge port of the feeding hopper, and the sealing plate is slidably connected to the bottom of the feeding hopper.

[0014] Furthermore, a mesh plate is adhered to the bottom of the functional panel.

[0015] Furthermore, the flattening assembly also includes a plurality of auxiliary pressure rollers disposed on the first support.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The cylindrical material cavity at the bottom of the hopper cooperates with the cross-shaped material distribution plate. When the material distribution plate rotates, it forms a sealed cavity with the arc surface of the material cavity. The volume of the sealed cavity can be accurately determined by controlling the volume of the sealed cavity. The first cylinder on the material injection side of the chain conveyor drives the sealing plate to slide. After the material distribution is completed, the outlet is immediately sealed to prevent residual slurry from dripping into the mold gap or detection sensing point, reduce the frequency of equipment cleaning, and reduce the risk of detection failure caused by slurry contamination.

[0018] 2. The automatic plate-laying mechanism uses a second cylinder to drive a connecting rod, which in turn drives the meshing first and second gears to rotate in opposite directions. This controls the synchronous movement of the baffle (supporting the functional plate) and the feeding plate (guiding the material drop), achieving precise control of "one plate at a time." A grid plate can be pre-attached to the bottom of the functional plate. The automatic plate-laying mechanism simultaneously places the grid plate into the slurry while placing the functional plate. The grid plate not only enhances the connection stability between the functional plate and the slurry but also suppresses the risk of cracking after product molding, thus extending the product's service life.

[0019] 3. The leveling and detection mechanism uses a third cylinder to drive a rack and pinion transmission, which in turn drives the main connecting rod and auxiliary connecting rod to smoothly press the leveling plate against the surface of the functional plate. The downward pressure overcomes the buoyancy of the slurry, pressing the functional plate to a preset height and correcting the tilt angle. This ensures the functional plate smoothly enters the subsequent leveling stage, avoiding production interruptions. The detection sensor on the bottom of the leveling plate works in conjunction with the sensing point of the stop block between the molds to achieve dual detection: first, detecting whether the functional plate is misaligned, avoiding batches of defective products; second, detecting the fitting accuracy between the leveling plate and the mold, promptly correcting equipment linkage errors, and improving production stability.

[0020] 4. The flattening component adopts a "drive wheel + driven wheel + ring belt" structure. The belt is closely attached to the surface of the blank under the action of the support wheel, and continuous rolling is achieved as the mold moves, which completely eliminates the problem of unevenness of the functional board caused by slurry expansion. The convex plate on the side of the first support is connected to the hydraulic cylinder. The convex plate is driven to rise and fall by the hydraulic cylinder, which can quickly adjust the height of the flattening component to meet the production needs of thermal insulation and sound insulation boards of different thicknesses.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] First, it should be noted that the chain conveyor 1 and the multiple soft molds 2 arranged on the chain conveyor 1 for cyclic transmission in this invention are both existing technical solutions. Therefore, the specific embodiments of this invention do not involve a detailed description of the specific chain conveyor solution. For specific solutions, please refer to the relevant content of the prior art described in the background section.

[0038] The flexible mold 2 of this invention includes a rectangular frame and four side strips disposed on the rectangular frame. The side strips are disposed on the top side of the rectangular frame and integrally connected to the rectangular frame. The rectangular frame has a receiving cavity for accommodating the blank. The rectangular frame is square, and the size of the receiving cavity is 60cm×60cm (the receiving cavity can be set in various sizes according to actual needs, such as 30cm×60cm, 40cm×40cm, 50cm×50cm, 40cm×80cm, etc.). The blank is formed into a 60cm×60cm heat-insulating and sound-absorbing board. The flexible mold 2 of this invention is made of silicone material, which facilitates demolding after the blank is formed.

[0039] Combination Figures 1 to 13 The automated continuous production equipment for prefabricated thermal insulation and soundproofing panels includes a chain conveyor 1, multiple flexible molds 2 spaced apart on the chain conveyor 1, and a hopper 3 for injecting slurry into the flexible molds 2. The chain conveyor 1 drives the multiple flexible molds 2 to circulate sequentially below the hopper 3. The hopper 3 is equipped with an equal-volume dispensing component 4 to inject an equal amount of slurry into each flexible mold 2. An automatic plate-laying mechanism 5 is provided across the top of the shell of the chain conveyor 1 across the flexible molds 2. As the chain conveyor moves, the automatic plate-laying mechanism 5 places functional plates 6 into each flexible mold 2 that has been injected with slurry. Downstream of the automatic plate-laying mechanism 5, a leveling and detection mechanism 7 is provided to perform at least one pre-leveling and position detection on the functional plates 6 in each flexible mold 2.

[0040] like Figure 1 As shown, in Figure 1 The platform frame is equipped with a chain conveyor 1 below it, and a large mixing equipment (omitted in the figure) is arranged on the platform frame. The mixing equipment is used to obtain slurry (such as cement slurry) for the production of prefabricated thermal insulation and sound insulation board modules. The slurry flows from the mixing equipment into the injection hopper 3, and then through the injection hopper 3 into multiple soft molds 2.

[0041] The blank in this invention includes a functional board 6 and a curing slurry. The functional board 6 is made of lightweight insulation material, such as polystyrene foam board, graphite polystyrene board, XPS extruded polystyrene board, polyurethane insulation board, rock wool insulation board, foam glass insulation board, or phenolic insulation board. The functional board 6 serves the functions of insulation and sound insulation. The curing slurry is an existing cement-based slurry, which flows out of the injection hopper 3 and enters the flexible mold 2 to form the blank. The contact surface between the functional board 6 and the slurry is a "plane". Because this "plane" is relatively rough and has many pits, it can stably connect with the slurry. A grid plate 10 can also be placed between the functional board 6 and the slurry. The grid plate 10 makes the connection between the functional board 6 and the slurry more stable and also plays a role in crack resistance. During the advance of the flexible mold 2 with the existing slurry, the grid plate 10 and the functional board 6 are placed in. After the slurry solidifies, the blank can form an insulation and sound insulation board.

[0042] Example 1

[0043] Combination Figure 1-2 As shown, the feeding side of the chain conveyor 1 is provided with a mounting frame 31, on which a first cylinder 32 is mounted. One end of the telescopic rod of the first cylinder 32 is connected to a sealing plate 33 for sealing the discharge port of the feeding hopper 3. The sealing plate 33 is slidably connected to the bottom of the feeding hopper 3. In use, when the soft mold 2 moves with the chain plate on the chain conveyor 1 to below the discharge port at the bottom of the feeding hopper 3, the first cylinder 32 is activated to pull the sealing plate 33 to slide, opening the discharge channel. The slurry will immediately flow downward from the discharge port into the soft mold 2. After the slurry flows downward for a certain period of time, when the soft mold 2 is about to leave below the feeding hopper 3, the first cylinder 32 is activated again to push the sealing plate 33 out to block the discharge port, thereby closing the slurry outflow channel. In this embodiment, the amount of slurry flowing into the soft mold 2 each time is controlled by controlling the flow time of the slurry, thereby injecting slurry into each soft mold 2 in sequence.

[0044] Example 2

[0045] In this embodiment, an equal-volume distribution component 4 is installed at the bottom of the injection hopper 3, which can directly realize the quantitative and precise injection of slurry:

[0046] The equal-volume material distribution component 4 includes a cylindrical material cavity 41 located at the bottom of the injection hopper 3. A cross-shaped material distribution plate 42 is rotatably installed inside the material cavity 41. When the material distribution plate 42 rotates, it will come into close contact with the arc surfaces on both sides of the material cavity 41 to form a sealed cavity 43. The sealed cavity 43 contains a quantitative amount of slurry injected into the soft mold 2. A reduction motor 44 is installed on the outer side of the injection hopper 3. The output end of the reduction motor 44 is connected to the rotating shaft of the material distribution plate 42.

[0047] like Figure 2As shown, the cross-shaped distribution plate 42 initially has an X-shape. Its two side plates on the horizontal side form a sealed cavity 43 with the arc wall of the material cavity 41. When the reduction motor 44 starts, it will drive the distribution plate 42 to rotate each time. As the distribution plate 42 rotates, the slurry in the injection hopper 3 is first transferred to the sealed cavity 43. Then, as it rotates, the slurry flows down from the outlet into the soft mold 2. After repeated rotation, a certain amount of slurry in the cavity is accurately injected into the soft mold 2 below. The slurry capacity can be controlled by controlling the size of the sealed cavity 43, and a sealing strip can be set on the end face of the distribution plate 42 to prevent the slurry in the sealed cavity 43 from leaking out. In addition, the speed of the reduction motor 44 can be adjusted according to the conveying speed of the chain conveyor 1 to ensure that each soft mold 2 receives an equal amount of slurry when it passes by.

[0048] Example 3

[0049] Combining Embodiment 1 and Embodiment 2, a sealing plate 33 and an equal-volume dispensing component 4 are installed at the bottom of the hopper 3. In this embodiment, driven by the reduction motor 44, the dispensing plate 42 dispenses the slurry and injects an equal amount of slurry into the soft mold 2. After the slurry flows out, the first cylinder 32 is immediately activated to push out the sealing plate 33 and block the outlet. This prevents the last remaining slurry on the surface of the dispensing plate 42 from dripping down onto the block between two adjacent soft molds 2. This would cause problems with the operation and cleaning of the soft mold 2 and the chain conveyor 1 over a long period of time. Furthermore, if the slurry drips onto the sensing point 78 on the block between two adjacent soft molds 2, it would cause a detection malfunction in the leveling detection mechanism 7. Therefore, this embodiment combines the two to complete the quantitative injection of slurry and prevent slurry from dripping. The residual slurry blocked by the sealing plate 33 will continue to flow into the soft mold 2 with a large amount of slurry as the sealing plate 33 is pulled open the next time.

[0050] In this invention, an automatic plate-laying mechanism 5 is designed to automate the placement of the functional plate 6. This mechanism is installed on top of the housing of the chain conveyor 1 and spans across the soft mold 2.

[0051] like Figure 3-6As shown, the automatic plate-laying mechanism 5 includes a plate-laying frame 51, in which multiple functional plates 6 are stacked. The side walls of the plate-laying frame 51 limit the movement of the functional plates 6. Plate-laying assemblies are provided on both sides of the plate-laying frame 51. Each plate-laying assembly includes a connecting plate 52 connected to the bottom of the plate-laying frame 51. A fixing plate 53 is provided on one side of the connecting plate 52 and perpendicularly connected to the side of the plate-laying frame 51. A first gear 54 and a second gear 55 are rotatably mounted on the side of the fixing plate 53 and mesh with each other. A second cylinder 56 is hinged on the connecting plate 52. The output end of the second cylinder 56 is connected to the central axis of the first gear 54 through a connecting rod 57. The output end of the second cylinder 56 is hinged to the connecting rod 57. A baffle 58 and a plate-laying plate 59 are fixedly connected to the ends of the central axes of the first gear 54 and the second gear 55, respectively. The central axes of the first gear 54 and the second gear 55 are both fixedly connected to the gears.

[0052] like Figure 4 As shown, multiple functional boards 6 are stacked inside the board placement frame 51 of the automatic board placement mechanism 5, in the initial state ( Figure 4 The baffles 58 on both sides support the bottom functional plate 6; when the soft mold 2 containing slurry moves to directly below the plate-laying frame 51, the second cylinder 56 is activated, driving the first gear 54 to rotate via the connecting rod 57. Since the first gear 54 and the second gear 55 mesh with each other, the rotation of the first gear 54 synchronously drives the second gear 55 to rotate in the opposite direction, such as... Figure 5 As shown, the rotation of the first gear 54 causes the baffle 58, which is fixedly connected to its central shaft, to rotate downwards and tilt. Meanwhile, the rotation of the second gear 55 in the opposite direction also causes the feeding plate 59, which is fixedly connected to its central shaft, to rotate upwards and tilt. At this time, due to the downward tilt of the baffle 58, the stacked functional plates 6 fall one plate position (the thickness of one functional plate 6) over the baffle 58 and are supported by the upwardly tilted feeding plate 59. Then, the second cylinder 56 resets, thereby causing the baffle 58 to rotate upwards via the first gear 54. At this time, the end of the baffle 58 is inserted obliquely into the bottom of the second-to-last functional plate 6 as it rotates. Figure 5 As the baffle 58 continues to rotate, it lifts up multiple stacked functional plates 6 (except for the bottom functional plate 6). Simultaneously, while the first gear 54 drives the baffle 58 to rotate upwards, the second gear 55 drives the discharge plate 59 to rotate downwards. As the discharge plate 59 rotates, the tilt angle gradually increases, and the bottom functional plate 6 passes over the discharge plate 59 and begins to fall downwards. Figure 6Finally, the material falls vertically onto the slurry in the soft mold 2, thus completing the feeding process. Afterwards, the baffle 58 and feeding plate 59 return to their initial positions, supporting the remaining functional plates 6 above, awaiting the arrival of the next soft mold 2. This feeding process utilizes the automatic feeding mechanism 5 in conjunction with the chain conveyor 1 to accurately place the functional plates 6 into the soft mold 2. Furthermore, through-holes are provided on both sides of the feeding frame 51. The baffle 58 and feeding plate 59 swing within these through-holes, thereby confining multiple stacked functional plates 6 within the feeding frame 51, preventing them from protruding from the bottom of the feeding frame 51. The through-holes also facilitate the installation and setting of the baffle 58 and feeding plate 59.

[0053] Example 4

[0054] When it is necessary to place the grid plate 10 in the grout to make the connection between the functional plate 6 and the grout more stable and also to play a role in crack resistance, the grid plate 10 can be pre-bonded to the bottom of the functional plate 6 (e.g., Figure 5 Then, they are stacked in the plate-laying rack 51, and as the automatic plate-laying mechanism 5 sequentially feeds the functional plates 6, they are placed together into the slurry in the soft mold 2; and after the bottom grid plate 10 of the functional plate 6, the distance between two adjacent functional plates 6 increases, making it easier for the end of the baffle 58 to be inserted into the bottom of the second to last functional plate 6.

[0055] After the automated automatic plate-feeding mechanism 5 of this invention feeds the material into the moving soft mold 2, the equipment cannot automatically and promptly pre-level the functional plate 6. This results in the functional plate 6 being obstructed when entering the subsequent flattening assembly 8 due to excessive floating height in the slurry, or warping due to tilting. Furthermore, it is difficult to quickly detect whether the functional plate 6 is accurately placed into the soft mold 2. Therefore, this invention utilizes a leveling detection mechanism 7 to perform leveling detection on the functional plate 6:

[0056] like Figure 7-11 As shown, the leveling and detection mechanism 7 includes a leveling plate 71. A main connecting rod 72 is hinged at the middle section of the side of the leveling plate 71, and two auxiliary connecting rods 73 are hinged at the tail section of the side of the leveling plate 71. An installation cavity is opened inside the housing of the chain conveyor 1. A third gear 74 is rotatably installed on the side cavity surface of the installation cavity. A rack 75 is connected to one side of the third gear 74 through a transmission. A third cylinder 76 is provided on one side of the rack 75. The output end of the third cylinder 76 is connected to the rack 75. The other end of the main connecting rod 72 is connected to the central shaft of the third gear 74. The other ends of the two auxiliary connecting rods 73 are both hinged to the side cavity surface of the installation cavity. Detection sensors 77 are provided at both ends of the bottom surface of the leveling plate 71. Sensing points 78 corresponding to the detection sensors 77 are installed on the blocks between two adjacent soft molds 2.

[0057] In such Figure 7 In this system, the leveling and testing mechanism 7 is basically installed inside the housing of the chain conveyor 1, while its drive unit (third cylinder 76, third gear 74, rack 75, main connecting rod 72, auxiliary connecting rod 73) can also be installed outside the housing of the chain conveyor 1, which facilitates maintenance.

[0058] The working process of the leveling and testing mechanism 7 is as follows: When the soft mold 2, carrying the functional plate 6, is about to move to a specific position, the third cylinder 76 is activated, pushing the rack 75 to move horizontally. The bottom of the rack 75 is provided with a limiting plate to slide and limit it. The rack 75 meshes with the third gear 74, driving the third gear 74 to rotate. Then, through the main connecting rod 72, the leveling plate 71 is pulled to rotate around the hinge point. At the same time, the two auxiliary connecting rods 73 on the side of the leveling plate 71 cooperate with the main connecting rod 72 to ensure that the leveling plate 71 descends smoothly and fits against the surface of the functional plate 6. The downward pressure of the leveling plate 71 presses down on the functional plate 6 in the slurry to level it. The leveling reduces the floating height of the functional plate 6 in the slurry and makes the functional plate 6 overcome tilting and keep the plate surface level.

[0059] The detection sensors 77 at both ends of the bottom surface of the adjusting plate 71 work synchronously. By sensing the sensing points 78 on the blocks between two adjacent soft molds 2, they determine whether the front-back and left-right positions of the functional plate within the mold meet the standards. For example, when the automatic plate-laying mechanism 5 is laying the plate, if the functional plate 6 is misaligned forward or backward, the functional plate 6 will block the sensing point 78. As a result, the detection sensor 77 cannot transmit signals to the sensing point 78, and the equipment can issue a signal to remind the machine to stop and adjust. In this invention, the detection sensors 77 and sensing points 78 are only provided on the front and rear blocks of the adjusting plate 71 and the soft mold 2. In actual production, if the functional plate 6 deviates from its left-right or other positions during plate laying, detection sensors 77 and sensing points 78 can be added at the corresponding positions.

[0060] The setting of the detection sensor 77 and the sensing point 78 can detect whether the automatic plate-laying mechanism 5 is correctly laying the plate (i.e., whether the functional plate 6 is properly placed in the soft mold 2). On the other hand, it can detect whether the leveling plate 71 in the leveling detection mechanism 7 is correctly pre-pressing and leveling the functional plate 6, so as to avoid the difference between the pressing position of the leveling plate 71 and the specific position of the movement of the soft mold 2 (i.e., the error in the coordination between the automatic plate-laying mechanism 5 and the chain conveyor 1), which would cause the functional plate 6 to tilt due to the pressing of the leveling plate 71.

[0061] Example 5

[0062] like Figure 10As shown, driven by the third cylinder 76, the main connecting rod 72 and the auxiliary connecting rod 73 cooperate to enable the adjusting plate 71 to pre-level and confirm the position of the functional plate 6. The output end of the third cylinder 76 can be selected to perform either an ejection-reset or a retraction-reset action. In this embodiment, when the output end of the third cylinder 76 is used for ejection, it drives the adjusting plate 71 to level and detect the functional plate 6 that has reached a specific position upstream. When the output end of the third cylinder 76 is used for retraction, it drives the adjusting plate 71 to level and detect the functional plate 6 that has reached a specific position downstream. Since the chain conveyor 1 drives the functional plate 6 in a moving state, both methods in this embodiment only perform one leveling and detection operation on the functional plate 6 within a single soft mold 2 that has passed through a specific upstream or downstream position.

[0063] Example 6

[0064] Compared to Embodiment 5, if the functional plate 6 within a single soft mold 2 is leveled only once, it is not possible to completely level the functional plate 6 within the soft mold 2. Therefore, it is necessary to use the leveling plate 71 in the leveling detection mechanism 7 to perform a second pressing and leveling on the same functional plate 6.

[0065] In this embodiment, both the main connecting rod 72 and the auxiliary connecting rod 73 are electric push rods, which are used to adjust the lateral distance of the adjusting plate 71 when it is pressed up and down in the moving direction of the soft mold 2; for example Figure 11 As shown, firstly, both the main connecting rod 72 and the auxiliary connecting rod 73 are in an extended state. Driven by the third cylinder 76, the adjusting plate 71 levels and inspects the functional plate 6 within the upstream soft mold 2. After the first leveling inspection, the main connecting rod 72, driven by the cylinder, returns from an upstream tilted state to a vertical state. Subsequently, the main connecting rod 72 and the auxiliary connecting rod 73 retract in length and rotate and tilt downstream as the third gear 74 reverses, thus pressing down and leveling the same functional plate 6 again. After the second leveling, the leveling inspection mechanism 7 resets (both the main connecting rod 72 and the auxiliary connecting rod 73 return to their extended state), and then performs the initial leveling of the next functional plate 6 upstream. This cycle of leveling and inspection is repeated. This allows the functional plate 6 within the same soft mold 2 to be leveled and inspected twice, ensuring that the leveling inspection mechanism 7 can fully level the plate to meet the pre-pressing state required for entering the flattening assembly 8. This avoids the need for repeated pressing and leveling after manual placement of the board, as well as the possibility of tilting or substandard functional board 6 due to manual leveling. The sensing point 78 can be set on the blocks added to the front, back, or sides of the soft mold 2.

[0066] In this invention, when the functional plate 6 is pressed onto the slurry, the slurry layer expands slightly due to the generation of air bubbles during the curing process, causing the functional plate 6 to become uneven. Therefore, this invention utilizes a flattening assembly 8 to continuously press it down. Within the flattening assembly 8, a belt 83 presses down on the functional plate 6. Compared to the adjusting plate 71, the belt 83 allows the uneven areas of the functional plate 6 to be continuously pressed downwards. After passing through the belt 83, the functional plate 6 is flattened, ensuring the consistency and flatness of the overall blank after molding, and guaranteeing the finished quality of the thermal insulation and soundproofing board.

[0067] like Figure 12 As shown, the flattening assembly 8 includes a first drive wheel 81, a first driven wheel 82 corresponding to the first drive wheel 81, and a belt 83 arranged in an annular shape between the first drive wheel 81 and the first driven wheel 82. When the soft mold 2 passes through the flattening assembly 8 driven by the chain conveyor 1, the belt 83 presses on the blank. The flattening assembly 8 also includes a first bracket 84 connected to both the first drive wheel 81 and the first driven wheel 82. The first bracket 84 is also equipped with a plurality of support wheels 85 for supporting the belt 83. The flattening assembly 8 also includes a plurality of auxiliary pressure rollers 86 arranged on the first bracket 84.

[0068] like Figure 13 As shown, after the functional plate 6 inside the soft mold 2 is pre-pressed and leveled by the leveling and detection mechanism 7, the billet (slurry + functional plate 6) moves to below the flattening assembly 8. The reduction motor installed on the outside of the first bracket 84 drives the annular belt 83 through the first drive wheel 81. Supported by the first driven wheel 82 and multiple support wheels 85, the belt 83 is tightly pressed against the surface of the billet. As the soft mold 2 moves, the belt 83 continuously and evenly rolls the billet, eliminating air bubbles inside the billet, making the surface of the billet flat, and at the same time enhancing the bonding strength between the slurry and the functional plate and the grid plate. In addition, multiple auxiliary pressure rollers 86 installed on the first bracket 84 further compact the billet, improving the overall flattening effect.

[0069] In addition, the present invention provides multiple sets of flattening components 8, which are arranged adjacent to each other in the length direction of the chain conveyor 1 housing. Since the working section of the belt 83 is short, the belt 83 will not deform, resulting in a better flattening effect on the blank on the soft mold 2.

[0070] In this invention, a height adjustment component 9 is also provided for adjusting the height of the flattening component 8 when producing thermal insulation and sound insulation boards of different thicknesses, such as... Figure 12As shown, the height adjustment component 9 includes a protruding plate 91 fixedly connected to the side of the first support 84. A hydraulic cylinder 92 is installed on the outer side of the chain conveyor 1 housing at the position corresponding to the protruding plate 91. The output end of the hydraulic cylinder 92 is connected to the protruding plate 91. Two hydraulic cylinders 92 are provided on both sides of each flattening component 8. When producing thermal insulation and sound insulation boards of different thicknesses, the hydraulic cylinders 92 of the height adjustment component 9 are activated. The output end of the hydraulic cylinder 92 pushes the protruding plate 91 to move up and down, thereby driving the first support 84 and the entire flattening component 8 to rise and fall, so that the contact pressure between the belt 83 and the blank is always kept within the optimal range, ensuring the flattening quality of products of different specifications.

[0071] Since the chain conveyor in this invention has a sufficient length (greater than 90 meters), the flattened billet continues to move with the soft mold 2. During the movement, the slurry enters a solidified state. Finally, the billet is demolded and unloaded from the tail of the chain conveyor. The empty soft mold 2 after unloading returns to the bottom of the injection hopper with the chain conveyor to start the next round of production, realizing fully automated continuous production.

[0072] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0073] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
