Description

Technical Field

[0001] The present invention relates to the processing technology of thermal insulation and sound insulation boards, and particularly relates to a pressure-holding mechanism for the forming of thermal insulation and sound insulation boards. Background Art

[0002] The thermal insulation and sound insulation board is composed of a casting layer and a precast core board. During processing, first, cement slurry is injected into the mold. Before the slurry solidifies, the core board is pressed on the slurry, and then the mold is sent into the pressure-holding mechanism to apply a certain pressure to the core board and maintain it for a period of time. After the slurry solidifies, a thermal insulation and sound insulation board with a double-layer composite structure can be formed.

[0003] In the Chinese invention patent with the publication number CN113733334A, a production line for thermal insulation and sound insulation boards is disclosed. In this production line for thermal insulation and sound insulation boards, the front and rear ends of the mold are simultaneously clamped by the first pressurizing unit and the second pressurizing unit to prevent the end of the core board from warping due to local pressure. The first pressurizing unit and the second pressurizing unit apply pressure to the core board to make the core board settle to a specified height, facilitating the mold to enter the downstream pressure-holding equipment. During the pressurizing process, the first pressurizing unit feeds synchronously with the mold, while the second pressurizing unit remains stationary, so that the mold gradually enters the downstream pressure-holding mechanism during the pre-pressurization process, reducing the pre-pressurization waiting time and improving production efficiency.

[0004] When the existing equipment is in use, the core board is pressed by the pressure-holding equipment. However, if it bears too much pressure at the beginning, it is easy to cause the front end of the core board to settle and the tail to warp, resulting in the core board shifting relative to the mold. At the same time, when the front end and the tail of the core board are subjected to force extrusion, the pressure distribution on them is uneven, resulting in too much or too little local pressure, making the forming of the thermal insulation and sound insulation board uneven. Therefore, a pressure-holding mechanism for the forming of thermal insulation and sound insulation boards has been developed. Summary of the Invention

[0005] The purpose of the present invention is to provide a pressure-holding mechanism for the forming of thermal insulation and sound insulation boards to solve the above deficiencies in the prior art.

A docking block is clamped at the lower end of the guiding block. The heat-insulating and sound-insulating board is pressed by the docking block.

[0010] As a further optimized solution of the present invention, a limiting block is fixedly installed on one side of the limiting block. An adjusting block is clamped at the lower end of the limiting block. At the same time, one side of the adjusting block is slidably connected to the side surface of the guiding block.

[0011] As a further optimized solution of the present invention, protective plates are fixedly installed at both ends of the lower end of the docking block. At the same time, a balance plate is rotatably installed at the middle position of the lower end of the docking block.

[0012] As a further optimized solution of the present invention, a moving block is slidably installed between the two protective plates. At the same time, a connecting block is fixedly installed between the two protective plates and on one side of the moving block. A telescopic member is fixedly installed at the end of the moving block. The end of the telescopic member away from the moving block is fixedly connected to the connecting block.

[0013] As a further optimized solution of the present invention, support rods are slidably installed at the ends of the moving block and the connecting block. The ends of the two support rods respectively penetrate and extend to the lower ends of the moving block and the connecting block.

[0014] At the same time, an elastic member is sleeved on the outer surface of the support rod. One end of the elastic member is fixedly connected to the ends of the moving block and the connecting block, and the other end is fixedly connected to the end of the support rod.

[0015] As a further optimized solution of the present invention, a pressing plate is fixedly installed at the lower end of the support rod. The heat-insulating and sound-insulating board is extruded by the pressing plate. At the same time, the upper end of the support rod is attached to the lower end of the balance plate.

[0016] As a further optimized solution of the present invention, the positioning component includes a bottom plate fixedly installed on one side of the base.

[0020] Compared with the prior art, a pressure maintaining mechanism for the forming of a heat preservation and sound insulation board provided by the present invention has the following beneficial effects: When one of the pressing plates first comes into contact with the heat preservation and sound insulation board, the balance plate is driven to rotate around the lower end of the docking block by the support rod, and then the support rod at the other end drives the other pressing plate to move downward. When the entire docking block slowly moves downward, the two pressing plates are gradually brought into a balanced state, so that the core plates are evenly distributed on the heat preservation and sound insulation board, thereby ensuring the quality of the heat preservation and sound insulation board.

[0021] An adjusting column is arranged between the two clamping plates, and a pressing plate is fixedly mounted at the lower end of the adjusting column. One side of the pressing plate is clamped with the outer surface of the pressing plate. Thus, after the pressing plate moves to the optimal position, the pressing plate is synchronously driven to move.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings.

Therefore, it should not be construed as a limitation to the present invention; the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Example: Please refer to Figures 1-8 , a pressure-holding mechanism for the forming of heat-insulating and sound-insulating boards, including a base 1. A support column 12 is fixedly installed at the upper end of the base 1, and a pressing assembly 2 is provided at the end of the support column 12. The heat-insulating and sound-insulating board is preliminarily extruded by the pressing assembly 2. At the same time, a mold 11 is attached to one side of the base 1.

[0036] In this solution, a component with a telescopic function such as an electric telescopic rod is fixedly arranged on the base 1 and is connected to an external control device. This component is fixedly connected to the support column 12, and the pressing assembly 2 arranged at its end is driven by the support column 12 to adjust the height so as to be applicable to the current scenario.

[0037] Furthermore, among them, the pressing assembly 2 includes a fixing plate 21 fixedly connected to the support column 12. A driving member 211 is fixedly installed at the lower end of the fixing plate 21. At the same time, a rotating plate 22 is fixedly installed at the output end of the driving member 211. Driving plates 23 are rotatably installed at both ends of the rotating plate 22, and positioning blocks 24 are rotatably installed at both ends of the driving plates 23.

[0038] In this embodiment, the driving member 211 is a device with power output such as a motor and is connected to an external control device. At the same time, when the driving member 211 is started, the rotating plate 22 arranged at its output end is synchronously driven to rotate. Since driving plates 23 are rotatably installed at both ends of the rotating plate 22, and in cooperation with the positioning blocks 24 rotatably installed on the driving plates 23, the rotating plate 22 drives the driving plates 23 to drive the positioning blocks 24 to move along the inner wall of the sliding groove 26 until the positioning blocks 24 reach the optimal position and then stop.

[0039] Furthermore, a limiting block 25 is fixedly installed at the lower end of the fixing plate 21. A sliding groove 26 is formed on one side of the limiting block 25. A slider 241 is slidably installed on the inner wall of the sliding groove 26. The upper end of the slider 241 is fixedly connected to the lower end of the positioning block 24. A slanting block 242 is fixedly installed at the lower end of the slider 241. A guiding block 281 is slidably installed on one side of the slanting block 242. A docking block 29 is clamped at the lower end of the guiding block 281. The heat-insulating and sound-insulating board is pressed by the docking block 29.

[0040] Specifically, when the positioning block 24 moves, the slider 241 fixedly installed at its lower end is synchronously driven to move. Since the outer surface of the slider 241 is slidably connected to the inner wall of the sliding groove 26, the slider 241 is limited, so that the slider 241 moves along the inner wall of the sliding groove 26.

[0041] For this explanation, the opposite sides of the slanting block 242 and the guiding block 281 are both inclined surfaces. When the slider 241 moves, the slanting block 242 fixedly installed at its lower end is driven to move. A guiding block 281 is slidably installed on one side of the slanting block 242, and one side of the guiding block 281 is longitudinally slidably installed on the adjusting block 28. Therefore, when the slanting block 242 moves, the guiding block 281 is driven to slowly move downward along the outer surface of the adjusting block 28.

[0042] Furthermore, a limiting block 27 is fixedly installed on one side of the limiting block 25. The lower end of the limiting block 27 is clamped with an adjusting block 28. At the same time, one side of the adjusting block 28 is slidably connected to the side surface of the guiding block 281.

[0043] Specifically, a plurality of docking holes are formed at the lower end of the limiting block 27. According to different scenarios, the adjusting block 28 is installed at a suitable position, and the docking holes and the adjusting block 28 are in interference fit, clamping the adjusting block 28 tightly in the docking holes, so as to cooperate with the slanting block 242 to squeeze the guiding block 281, making it suitable for different scenarios.

[0044] A guiding groove is formed on one side of the adjusting block 28, and elastic components such as springs are arranged on the inner wall of the guiding groove. The inner wall of the guiding groove is slidably connected to the outer surface of the guiding block 281, and one end of the spring is connected to the inner wall of the guiding groove, and the other end is connected to the end of the guiding block 281. Therefore, after the guiding block 281 is squeezed by the slanting block 242, the guiding block 281 can be restored to the initial position by the acting force of the spring.

[0045] Furthermore, protective plates 291 are fixedly installed at both ends of the lower end of the docking block 29. At the same time, a balance plate 292 is rotatably installed at the middle position of the lower end of the docking block 29.

[0046] A moving block 293 is slidably installed between two protective plates 291. At the same time, a connecting block 294 is fixedly installed between the two protective plates 291 and on one side of the moving block 293. One end of the moving block 293 is fixedly installed with a telescopic member 298, and the end of the telescopic member 298 away from the moving block 293 is fixedly connected to the connecting block 294.

[0047] Specifically, a moving groove is formed between the two protective plates 291, and the inner wall of the moving groove is slidably connected to the outer surface of the moving block 293, so that the moving block 293 remains stable as a whole when moving.

[0048] The telescopic member 298 is an existing telescopic rod with a spring body built therein, which is used to limit the moving block 293 and the connecting block 294. The moving block 293 and the connecting block 294 remain stable during operation, and the distance between the moving block 293 and the connecting block 294 can be adjusted according to the actual situation to make it suitable for the current scenario.

[0049] Further, support rods 295 are slidably installed at the ends of the moving block 293 and the connecting block 294 respectively. The ends of the two support rods 295 respectively penetrate and extend to the lower ends of the moving block 293 and the connecting block 294. At the same time, an elastic member 296 is sleeved on the outer surface of the support rod 295. One end of the elastic member 296 is fixedly connected to the ends of the moving block 293 and the connecting block 294, and the other end is fixedly connected to the end of the support rod 295.

[0050] Specifically, the elastic member 296 is an elastic component such as a spring. By limiting the support rod 295 with the elastic member 296, when the support rod 295 cooperates with the pressing plate 297 to fit with the thermal insulation and sound insulation board, it tightly presses on its surface, and both ends of the pressing are kept horizontal. Ensure that the pressure distribution at the front end and the tail end of the thermal insulation and sound insulation board is consistent.

[0051] Further, a pressing plate 297 is fixedly installed at the lower end of the support rod 295. The thermal insulation and sound insulation board is squeezed by the pressing plate 297. At the same time, the upper end of the support rod 295 is in contact with the lower end of the balance plate 292.

[0052] Specifically, the thermal insulation and sound insulation board is pressed by the pressing plate 297, so that the core board is evenly distributed on the thermal insulation and sound insulation board, thereby ensuring the quality of the thermal insulation and sound insulation board.

[0053] When one of the pressing plates 297 comes into contact with the thermal insulation and sound insulation board first, the balance plate 292 is driven by the support rod 295 to rotate around the lower end of the docking block 29, and then the support rod 295 at the other end drives the other pressing plate 297 to move downward. When the entire docking block 29 moves downward slowly, the two pressing plates 297 are driven to be gradually in a balanced state.

[0054] Further, a positioning component 3 is assembled on one side of the base 1. Meanwhile, the positioning component 3 is located above the mold 11, and the pressed heat-insulating and sound-insulating board is limited by the positioning component 3. The positioning component 3 includes a bottom plate 31 fixedly installed on one side of the base 1. A power component 32 is fixedly installed at the end of the bottom plate 31, and a power plate 33 is fixedly installed at the output end of the power component 32.

[0055] In this embodiment, the power component 32 is a device with a telescopic function such as an electric telescopic rod, and is connected to an external control device. Meanwhile, when the power component 32 is started, the power plate 33 arranged at its output end is synchronously driven to move.

[0056] Further, movable blocks 34 are symmetrically and slidably installed on the outer surface of the power plate 33. One end of each movable block 34 is rotatably installed with a movable rod 35, and the end of the movable rod 35 far from the movable block 34 is rotatably connected to the outer surface of the bottom plate 31.

[0057] Specifically, when the power plate 33 moves, the movable blocks 34 slidably installed on its outer surface are synchronously driven to move. Since the movable rod 35 is rotatably installed on the movable block 34, the movement of the power plate 33 cooperates with the movable rod 35 to drive the movable block 34 to slide on the power plate 33.

[0058] Further, a push rod 36 is rotatably installed at one end of the movable block 34 and on one side of the movable rod 35. Meanwhile, a moving rod 38 is rotatably installed at the end of the push rod 36. One end of the bottom plate 31 is fixedly installed with a sliding plate 37, and the inner wall of the sliding plate 37 is slidably connected to the outer surface of the moving rod 38.

[0059] Specifically, when the movable block 34 moves, the push rod 36 rotatably installed at its end is driven to move. Since the end of the push rod 36 is rotatably connected to the outer surface of the moving rod 38, when the push rod 36 moves, the moving rod 38 is driven to move along the inner wall of the sliding plate 37, so that the two sliding plates 37 move towards the middle or move towards both sides synchronously.

[0060] Further, a clamping plate 39 is fixedly installed at the end of the moving rod 38, and the pressed heat-insulating and sound-insulating board is locked by the clamping plate 39.

[0061] Specifically, when the moving rod 38 moves, the clamping plate 39 fixedly installed at its end is driven to move towards the middle or move towards both sides.

[0062] An adjusting column is arranged between the two clamping plates 39. The lower end of the adjusting column is fixedly installed with an extrusion plate, and one side of the extrusion plate is clamped with the outer surface of the pressing plate 297. Thus, after the pressing plate 297 moves to the optimal position, the extrusion plate is synchronously driven to move. After the movement, the adjusting column on the extrusion plate is fixed by the clamping plate 39, thereby ensuring the overall accuracy and consistency.

[0063] The control device can select a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which consists of an arithmetic unit, a controller, a memory, input and output devices, etc., and is equivalent to a mini computer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes more on self-supply (without external hardware) and cost savings. Its greatest advantage is its small size, which can be placed inside the instrument, but it has a small storage capacity, simple input and output interfaces, and low power consumption.

[0064] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
