Abstract
Description
Technical Field
[0001] This invention relates to the field of gypsum board production technology, specifically to a gypsum board forming thickness adjustment device and adjustment method. Background Technology
[0002] Gypsum board is a building material made primarily from gypsum. During production, the gypsum is calcined, and the calcined gypsum powder is mixed with various ingredients and water in a specific ratio to form a slurry. This slurry is then conveyed onto a lower protective paper on a belt conveyor. After initial solidification, the protective paper is covered onto the discharged slurry. The process involves extrusion, gluing, solidification, separation, drying, edge sawing, and edge sealing to produce gypsum board. To meet the production requirements of gypsum board in different specifications, thickness adjustment devices are often used to adjust the distance between the forming belt and the forming table, thereby regulating the extruded thickness of the gypsum board, ensuring accuracy in thickness, and improving product quality.
[0003] Existing gypsum board forming thickness adjustment equipment and methods have drawbacks. Because the gypsum slurry is not fully shaped during extrusion, the gypsum board that has just been extruded from the forming board will undergo surface expansion and deformation due to the release of internal stress. In severe cases, cracking may even occur. This will cause the actual thickness of the gypsum board to exceed the thickness value set during adjustment. Therefore, not only is the forming thickness of the gypsum board not accurately adjusted, but the forming quality of the gypsum board is also reduced. Summary of the Invention
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this invention provides a gypsum board molding thickness adjustment device and method, which solves the problem that because the gypsum slurry is not fully shaped during extrusion, the gypsum board immediately after extrusion from the molding plate will undergo surface expansion and deformation due to the release of internal stress, and in severe cases, even cracking. This will cause the actual thickness of the gypsum board to exceed the thickness value set during adjustment, thus not only making the gypsum board molding thickness adjustment inaccurate, but also reducing the molding quality of the gypsum board.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, the present invention provides the following technical solution: a gypsum board forming thickness adjustment device and its adjustment method, comprising a base, an extrusion conveyor belt fixedly mounted on the top of the base, a support roller fixedly mounted on the top of the base, the support roller abutting against the bottom of the extrusion conveyor belt, a bracket fixedly connected to the top of the base, the bracket located on the top side of the extrusion conveyor belt, a central controller fixedly connected to the front of the bracket, a hydraulic cylinder fixedly mounted on the top of the bracket, a hydraulic rod fixedly connected to the output end of the hydraulic cylinder, an adjusting plate fixedly connected to the bottom end of the hydraulic rod, an extrusion plate disposed on the bottom side of the adjusting plate, an electric telescopic rod fixedly connected between the adjusting plate and the extrusion plate, a stress relief mechanism disposed on one side of the top of the extrusion plate, a cooling mechanism disposed at the output end of the extrusion plate, the cooling mechanism being located on one side of the stress relief mechanism, the stress relief mechanism comprising a release component and a drying component, the release component being disposed on one side of the top of the extrusion plate. The drying component is located on top of the release component. In this invention, when the gypsum board is formed, the required thickness of the gypsum board is first adjusted. During adjustment, the hydraulic cylinder activates the hydraulic rod to move the adjusting plate. After moving to the approximate position, the electric telescopic rod moves the extrusion plate until it reaches the appropriate position. At this point, the distance between the extrusion plate and the extrusion conveyor belt is the thickness of the gypsum board. During the adjustment process, a height sensor monitors the process in real time to facilitate real-time adjustment of the gypsum board thickness. After adjustment, gypsum slurry is transported to the input end of the extrusion plate by external equipment. Due to the continuous rotation of the extrusion conveyor belt, the gypsum slurry passes through the extrusion plate and is extruded to obtain the gypsum board. Before the gypsum board is output from the extrusion plate, the stress release mechanism releases the stress on the surface of the unformed gypsum board to prevent deformation during the extrusion process. Furthermore, the cooling mechanism cools the surface of the gypsum board to prevent thermal expansion caused by the heating in the previous process.
[0008] Preferably, the release assembly includes a fixed shell, which is fixedly connected to the top side of the extrusion plate. Pressure sensors are fixedly connected to both sides inside the fixed shell, and a first elastic telescopic rod is fixedly connected to the bottom of the pressure sensor. The bottom ends of the two first elastic telescopic rods are fixedly connected to a mounting plate.
[0009] Preferably, the surface of the extrusion plate is provided with a through hole, the through hole is located on the bottom side of the fixed shell, and two second elastic telescopic rods are fixedly connected to the bottom sides of the mounting plate, and a roller shaft is rotatably connected between the bottom ends of the two second elastic telescopic rods.
[0010] Preferably, the second elastic telescopic rod and the roller are provided in multiple sets, and the bottom of the multiple sets of rollers is located on the same horizontal plane as the bottom of the through hole.
[0011] In this invention, when the stress on the surface of the gypsum board is released by the release component, the roller is pressed against the surface of the gypsum board by the action of the first and second elastic telescopic rods, thereby releasing the stress on the surface of the gypsum board onto the surface of the roller. The pressure sensor monitors the pressure on the roller, and when the accumulated pressure is too large, the operation stops to release the force on the roller. The double-row roller arrangement allows for secondary release, making the stress on the surface of the gypsum board more thorough. The first elastic telescopic rod can quickly release the overall stress of the gypsum board, and then the multiple rollers on the second elastic telescopic rod can release the minute stresses at different locations accordingly, making the release more precise. The release component can quickly and roughly release most of the stress, and then precisely release the minute stresses, so that the stress on the surface of the gypsum board is released, preventing the gypsum board from expanding and deforming due to stress when it is extruded.
[0012] Preferably, the drying assembly includes an air distribution shell, which is fixedly connected to the top of a fixed shell. An air outlet pipe is fixedly connected to the bottom of the air distribution shell. The number of air outlet pipes is set to multiple, and the bottom ends of the multiple air outlet pipes pass through the top wall of the fixed shell and extend into the interior of the fixed shell.
[0013] Preferably, a fan is fixedly installed on the top of the regulating plate, a flexible hose is connected to the output end of the fan, a heating shell is fixedly connected to one side of the air distribution shell, one end of the flexible hose is connected to the surface of the heating shell and communicates with the heating shell, and a heater is fixedly connected inside the heating shell.
[0014] In this invention, the drying component can dry the moisture on the surface of the gypsum board to a certain extent, making it less prone to hydration reaction. During drying, the fan is turned on and blows air through a hose into the heating shell, then into the air distribution shell, and finally blown onto the surface of the gypsum board through the air outlet pipe to dry the surface of the gypsum board. At the same time, the blown air is heated by the heater, so that the hot air blown out of the air outlet pipe dries the surface of the gypsum board faster, so that the gypsum board can be quickly dried as it passes quickly over the bottom side of the fixed shell.
[0015] Preferably, a motor is fixedly installed at one end of the air distribution shell, the output end of the motor passes through the outer wall of the air distribution shell and is fixedly connected to a bidirectional lead screw, one end of the bidirectional lead screw is rotatably connected to the inner wall of the air distribution shell, and air distribution perforated plates are meshed on both sides of the surface of the bidirectional lead screw.
[0016] In this invention, a motor drives a bidirectional lead screw to rotate back and forth repeatedly. The bidirectional lead screw drives the air distribution plates on both sides to rotate back and forth, thereby dispersing the air blown out by the fan back and forth. This allows the blown air to be evenly distributed, so that the blown air can be blown more evenly onto the surface of the gypsum board, making it dry more evenly and improving the drying effect.
[0017] Preferably, the cooling mechanism includes a flat plate, which is fixedly connected to the output end of the extrusion plate. The flat plate is made of a thermally conductive material, and a height sensor is fixedly connected to the top of the flat plate. The detection end of the height sensor is located on the same horizontal plane as the bottom of the flat plate.
[0018] Preferably, a condenser pipe is fixedly connected inside the flat plate, a fixing plate is fixedly connected to one side of the top of the flat plate, a cooler is fixedly installed on one side of the fixing plate, and both ends of the condenser pipe pass through the inner wall of the flat plate and are connected to the bottom of the cooler.
[0019] In this invention, the cooling mechanism can cool the surface of the gypsum board to prevent it from expanding and deforming due to heating in the previous process. During operation, the refrigeration unit is activated to cool the refrigerant in the condenser tube. The cooled condenser tube cools the heat-conducting flat plate, thereby absorbing the heat from the gypsum board surface and achieving a certain cooling effect. At the same time, the flat plate can also make the surface of the gypsum board smoother and keep the thickness of the gypsum board as consistent as possible, thus making the thickness adjustment more precise.
[0020] A method for adjusting the thickness of a gypsum board forming device includes the following steps:
[0021] S1. First, the hydraulic rod drives the adjusting plate and the extrusion plate to move downwards together for coarse adjustment. Then, the electric telescopic rod is started to drive the extrusion plate to continue moving for fine adjustment. During the coarse and fine adjustment, the thickness of the gypsum board is monitored by the height sensor until the required thickness is achieved.
[0022] S2. After adjustment, the gypsum slurry is extruded and shaped by the extrusion plate. The stress on the surface of the gypsum board is released by the release component. Before the gypsum board is output from the bottom of the extrusion plate, the stress on the surface of the gypsum board is released to the surface of the roller, and then transmitted to the pressure sensor through the second elastic telescopic rod and the first elastic telescopic rod. The stress value is monitored by the pressure sensor.
[0023] S3. While releasing stress, the surface of the gypsum board to be output is lightly dried by the drying component to temporarily increase the hardness of the gypsum board surface and prevent it from being easily deformed. During drying, the air blown out by the fan is heated by the heater to form hot air. The hot air passes through the through hole and blows onto the surface of the gypsum board for a certain drying treatment.
[0024] S4. After drying reduces the moisture on the surface of the gypsum board, the surface of the gypsum board is cooled by a cooling mechanism. The refrigerant in the condenser is cooled by a refrigeration unit. Due to the thermal conductivity of the flat plate, the temperature of the flat plate is reduced, so that the gypsum board can be cooled and leveled when passing through the flat plate.
[0025] S5. After stress relief, the gypsum board is less prone to expansion and deformation during extrusion. After being leveled by a flat plate, it becomes more level and even. Finally, the thickness measured by the height sensor is more accurate.
[0026] (III) Beneficial Effects
[0027] This invention provides a gypsum board forming thickness adjustment device and method. It has the following beneficial effects:
[0028] (I) The gypsum board forming thickness adjustment equipment and its adjustment method, through the setting of the stress release mechanism, can release the stress on the surface of the gypsum board, prevent the deformation caused by stress release during the extrusion of the gypsum board, and at the same time dry the moisture on the surface of the gypsum board by blowing air, reduce the hydration reaction and enhance the toughness of the gypsum board surface, reduce the possibility of gypsum board expansion and deformation, make the surface of the gypsum board smoother, and make its actual thickness closer to the adjusted thickness, thereby improving the accuracy of thickness adjustment and improving the forming quality of the gypsum board.
[0029] (II) The gypsum board forming thickness adjustment equipment and its adjustment method, through the setting of the first elastic telescopic rod, the second elastic telescopic rod and the double-row cutting multiple sets of rollers, the first elastic telescopic rod can quickly release most of the stress of the gypsum board as a whole, and then the multiple second elastic telescopic rods and rollers can release the corresponding minor stress at different positions, which is more precise and prevents the situation where local minor stress is not released, further reducing the possibility of deformation during gypsum board extrusion and improving the forming quality.
[0030] (III) The gypsum board forming thickness adjustment equipment and its adjustment method, through the setting of the drying components, enable the hot air blown by the fan to better dry the surface of the gypsum board, reduce the moisture on the surface of the gypsum board, and make it less prone to deformation. Furthermore, through the setting of the air distribution shell, air distribution perforated plate, etc., the blown air can be made more uniform, thereby enabling the surface of the gypsum board to dry evenly, improving the drying effect, preventing deformation caused by uneven drying of the gypsum board surface, and improving the production quality of gypsum board.
[0031] (iv) The gypsum board forming thickness adjustment equipment and its adjustment method, through the setting of the cooling mechanism, can cool down the temperature that rises during the previous drying and heating process, prevent the gypsum board surface from expanding and deforming due to heat, and improve the forming quality of the gypsum board. At the same time, through the action of the leveling plate, the flatness of the gypsum board surface is improved, and the gypsum board surface is further leveled, so that the measured thickness of the gypsum board is more accurate and closer to the adjusted thickness, and further improves the accuracy of gypsum board thickness adjustment.

[0042] 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.
[0043] See Figure 1-9 This invention provides a technical solution: a gypsum board forming thickness adjustment device, the structure of which includes a base 1, an extrusion conveyor belt 2 fixedly installed on the top of the base 1, a support roller 3 fixedly installed on the top of the base 1, the support roller 3 abutting against the bottom of the extrusion conveyor belt 2, a bracket 4 fixedly connected to the top of the base 1, the bracket 4 located on the top side of the extrusion conveyor belt 2, a central controller 5 fixedly connected to the front of the bracket 4, a hydraulic cylinder fixedly installed on the top of the bracket 4, a hydraulic rod 6 fixedly connected to the output end of the hydraulic cylinder, an adjusting plate 7 fixedly connected to the bottom end of the hydraulic rod 6, an extrusion plate 8 arranged on the bottom side of the adjusting plate 7, an electric telescopic rod 9 fixedly connected between the adjusting plate 7 and the extrusion plate 8, a stress release mechanism 10 arranged on one side of the top of the extrusion plate 8, a cooling mechanism 11 arranged on the output end of the extrusion plate 8, the cooling mechanism 11 located on one side of the stress release mechanism 10, the stress release mechanism 10 including a release component 101 and a drying component 102, the release component 101 arranged on one side of the top of the extrusion plate 8, and the drying component 102 arranged on the top side of the extrusion plate 8. On the top of component 101, specifically, during the gypsum board forming process, the required thickness of the gypsum board is first adjusted. During adjustment, the hydraulic cylinder activates the hydraulic rod 6 to move the adjusting plate 7. After moving to the approximate position, the electric telescopic rod 9 moves the extrusion plate 8 until it reaches the appropriate position. At this point, the distance between the extrusion plate 8 and the extrusion conveyor belt 2 is the thickness of the gypsum board. During the adjustment process, the height sensor 112 monitors in real time to facilitate real-time adjustment of the gypsum board thickness. After adjustment, gypsum slurry is transported to the input end of the extrusion plate 8 through external equipment. Due to the continuous rotation of the extrusion conveyor belt 2, the gypsum slurry passes through the extrusion plate 8 and is extruded to obtain the gypsum board. Before the gypsum board is output from the extrusion plate 8, the stress release mechanism 10 releases the stress on the surface of the unformed gypsum board to prevent deformation during the extrusion process. Furthermore, the cooling mechanism 11 cools the surface of the gypsum board to prevent the gypsum board from expanding due to the heating in the previous process.
[0044] The release assembly 101 includes a fixed shell 1011, which is fixedly connected to the top side of the extrusion plate 8. Pressure sensors 1012 are fixedly connected to both sides inside the fixed shell 1011. A first elastic telescopic rod 1013 is fixedly connected to the bottom of the pressure sensor 1012. The bottom ends of the two first elastic telescopic rods 1013 are fixedly connected to a mounting plate 1014.
[0045] The extrusion plate 8 has a through hole 1015 on its surface, which is located on the bottom side of the fixed shell 1011. Two second elastic telescopic rods 1016 are fixedly connected to the bottom sides of the mounting plate 1014, and a roller 1017 is rotatably connected between the bottom ends of the two second elastic telescopic rods 1016.
[0046] The second elastic telescopic rod 1016 and the roller 1017 are provided in multiple sets, and the bottom of the multiple sets of rollers 1017 is on the same horizontal plane as the bottom of the through hole 1015.
[0047] Specifically, when the stress on the gypsum board surface is released by the stress release component 101, the action of the first elastic telescopic rod 1013 and the second elastic telescopic rod 1016 causes the roller 1017 to press against the surface of the gypsum board, thereby releasing the stress on the surface of the gypsum board onto the surface of the roller 1017. The pressure sensor 1012 monitors the pressure on the roller 1017, and if the accumulated pressure is too high, the system will stop to release the force on the roller 1017. Furthermore, the double-row roller 1017 configuration allows for secondary stress release, ensuring the stress on the gypsum board surface is effectively relieved. The stress is released more thoroughly, and the first elastic telescopic rod 1013 can quickly release the stress of the entire gypsum board. Then, the multiple second elastic telescopic rods 1016 and multiple rollers 1017 can release the minute stresses at different locations accordingly, making the release more precise. The release component 101 can quickly and roughly release most of the stress, and then precisely release the minute stresses, so that the stress on the surface of the gypsum board is released, avoiding expansion and deformation of the gypsum board due to stress when it is extruded.
[0048] The drying assembly 102 includes an air distribution shell 1021, which is fixedly connected to the top of the fixed shell 1011. An air outlet pipe 1022 is fixedly connected to the bottom of the air distribution shell 1021. The number of air outlet pipes 1022 is set to multiple, and the bottom ends of the multiple air outlet pipes 1022 pass through the top wall of the fixed shell 1011 and extend into the interior of the fixed shell 1011.
[0049] Among them, a fan 1023 is fixedly installed on the top of the regulating plate 7, and a hose 1024 is connected to the output end of the fan 1023. A heating shell 1025 is fixedly connected to one side of the air distribution shell 1021. One end of the hose 1024 is connected to the surface of the heating shell 1025 and communicates with the heating shell 1025. A heater 1026 is fixedly connected inside the heating shell 1025.
[0050] Specifically, the drying component 102 can dry the moisture on the surface of the gypsum board to a certain extent, making it less prone to hydration reaction. During drying, the fan 1023 is turned on to blow air, which enters the heating shell 1025 through the hose 1024, then enters the air distribution shell 1021, and finally blows onto the surface of the gypsum board through the air outlet 1022 to dry the surface of the gypsum board. At the same time, the heater 1026 heats the blown air, so that the hot air blown out of the air outlet 1022 dries the surface of the gypsum board faster, so that the gypsum board can be quickly dried when it passes the bottom side of the fixing shell 1011.
[0051] Among them, a motor 1027 is fixedly installed at one end of the air distribution shell 1021. The output end of the motor 1027 passes through the outer wall of the air distribution shell 1021 and is fixedly connected to a bidirectional lead screw 1028. One end of the bidirectional lead screw 1028 is rotatably connected to the inner wall of the air distribution shell 1021. Air distribution perforated plates 1029 are meshed on both sides of the surface of the bidirectional lead screw 1028.
[0052] Specifically, the motor 1027 drives the bidirectional lead screw 1028 to rotate back and forth repeatedly. The bidirectional lead screw 1028 drives the air distribution plates 1029 on both sides to rotate back and forth, thereby dispersing the air blown out by the fan 1023 back and forth. This allows the blown air to be evenly distributed, so that the blown air can be blown more evenly onto the surface of the gypsum board, making it dry more evenly and improving the drying effect.
[0053] The cooling mechanism 11 includes a flat plate 111, which is fixedly connected to the output end of the extrusion plate 8. The flat plate 111 is made of thermally conductive material. A height sensor 112 is fixedly connected to the top of the flat plate 111, and the detection end of the height sensor 112 is on the same horizontal plane as the bottom of the flat plate 111.
[0054] The plate 111 has a condenser pipe 113 fixedly connected inside, a fixing plate 114 fixedly connected to one side of the top of the plate 111, a cooler 115 fixedly installed on one side of the fixing plate 114, and the two ends of the condenser pipe 113 pass through the inner wall of the plate 111 and are connected to the bottom of the cooler 115.
[0055] Specifically, the cooling mechanism 11 can cool the surface of the gypsum board to prevent it from expanding and deforming due to heating in the previous process. During operation, the cooler 115 is activated to cool the refrigerant in the condenser tube 113. The cooled condenser tube 113 cools the heat-conducting flat plate 111, thereby absorbing the heat from the gypsum board surface that passes through the flat plate 111, achieving a certain cooling effect. At the same time, the flat plate 111 can also make the surface of the gypsum board smoother and keep the thickness of the gypsum board as consistent as possible, thus making the thickness adjustment more precise.
[0056] A method for adjusting the thickness of a gypsum board forming device includes the following steps:
[0057] S1. First, the hydraulic rod 6 drives the adjusting plate 7 and the extrusion plate 8 to move downward together for coarse adjustment. Then, the electric telescopic rod 9 is started to drive the extrusion plate 8 to continue moving for fine adjustment. During the coarse and fine adjustment, the thickness of the gypsum board is monitored by the height sensor 112 until the required thickness is achieved.
[0058] S2. After adjustment, the gypsum slurry is extruded and formed by the extrusion plate 8. The stress on the surface of the gypsum board is released by the release component 101. Before the gypsum board is output from the bottom of the extrusion plate 8, the stress on the surface of the gypsum board is released to the surface of the roller 1017, and then transmitted to the pressure sensor 1012 through the second elastic telescopic rod 1016 and the first elastic telescopic rod 1013. The stress value is monitored by the pressure sensor 1012.
[0059] S3. While releasing stress, the surface of the gypsum board to be output is lightly dried by the drying component 102 to temporarily increase the hardness of the gypsum board surface and prevent it from being easily deformed. During drying, the air blown out by the fan 1023 is heated by the heater 1026 to form hot air. The hot air passes through the through hole 1015 and blows onto the surface of the gypsum board for a certain drying treatment.
[0060] S4. After drying reduces the moisture on the surface of the gypsum board, the surface of the gypsum board is cooled by the cooling mechanism 11. The refrigerant in the condenser 113 is cooled by the refrigerator 115. Due to the thermal conductivity of the flat plate 111, the temperature of the flat plate 111 is reduced, so that the gypsum board can be cooled and leveled when passing through the flat plate 111.
[0061] S5. After stress relief, the gypsum board is less prone to expansion and deformation during extrusion. After being leveled by the flat plate 111, it becomes more level and even. Finally, the thickness measured by the height sensor 112 is more accurate.
