Description

Technical Field

[0001] This invention relates to the field of gypsum board production, and more particularly to a molding device for gypsum board production. Background Technology

[0002] Gypsum board is a material made primarily from building gypsum. It is a lightweight, high-strength, thin, easy-to-process building material with good sound insulation, heat insulation, and fire resistance properties. The extrusion molding process of gypsum board involves pouring a fixed amount of gypsum slurry into a closed mold with upper and lower molds, and then pressing the slurry in the mold into the required shape and density under great pressure.

[0003] Existing gypsum board production molding equipment usually requires demolding to remove the gypsum board, which is not easy to remove the pressed gypsum board, affecting the production efficiency of gypsum board. It is also not easy to spread the gypsum evenly in the molding mold, and the pressing device is prone to sticking residual gypsum. During production, air bubbles and gaps are easily left in the gypsum, thus affecting the production quality of gypsum board. Summary of the Invention

[0004] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides a molding device for gypsum board production, which can easily remove the pressed gypsum board blank, facilitate the uniform rolling and tapping of gypsum, and facilitate the cleaning of sticky residual gypsum material, thereby effectively improving the production efficiency and quality of gypsum board.

[0005] The technical solution is as follows: A molding device for gypsum board production includes a frame, fixed rods, electric push rods, a mounting frame, and a molding die. Four fixed rods are installed on the frame, and two electric push rods are installed on the frame. The two electric push rods are symmetrically arranged, and the telescopic rods of both electric push rods extend out. A mounting frame is installed on both electric push rods. The mounting frame is slidably connected to the four fixed rods. A molding die is fixedly connected to the frame, and the mounting frame is located above the molding die.

[0006] Furthermore, it also includes a molding mechanism, which is installed on the frame. The molding mechanism includes a pressure plate, a support block, a movable frame, and a support plate. The pressure plate is installed at the bottom of the mounting frame. The support block is fixedly connected to the frame. The movable frame is slidably connected to the frame. The support plate is fixedly connected to the movable frame. The support plate is located in the upper part of the molding mold and below the pressure plate.

[0007] Furthermore, the movable frame is equipped with a sliding groove, and the support block is located in the sliding groove of the movable frame, so that the support block will disengage from the movable frame.

[0008] Furthermore, it also includes a scraping mechanism, which is mounted on the frame. The scraping mechanism includes a swing frame, a torsion spring, a rotating roller, and a collection trough. Two swing frames are rotatably connected to the mounting frame and are arranged symmetrically. Two torsion springs are connected between each swing frame and the mounting frame. A rotating roller is rotatably connected to each swing frame and is located between the pressure plate and the support plate. Two collection troughs are fixedly connected to the frame and are arranged symmetrically. The two collection troughs are located on both sides of the forming mold and are located below the rotating roller.

[0009] Furthermore, it includes a cleaning mechanism mounted on the frame. The cleaning mechanism includes limit rods, sliding frames, guide plates, and scrapers. Two limit rods are fixedly connected to the mounting frame and are symmetrically arranged. Two sliding frames are slidably connected to the two limit rods. Two sets of guide plates are mounted on the frame and are symmetrically arranged. Each guide plate has an inclined groove. The two sliding frames are slidably connected to the inclined grooves of the two sets of guide plates respectively. Each sliding frame is equipped with a scraper, and each scraper contacts the bottom of the pressure plate.

[0010] Furthermore, it also includes a striking mechanism, which is mounted on the frame. The striking mechanism includes a rack, a rotating shaft, meshing gears, protrusions, a limiting bracket, a movable rod, a support spring, a sliding rod, a return spring, and striking blocks. Two racks are fixedly connected to the mounting bracket and are symmetrically arranged. A rotating shaft is rotatably connected to the frame, and two meshing gears are fixedly connected to the rotating shaft. Two protrusions are fixedly connected to the rotating shaft and are symmetrically arranged. Two limiting brackets are fixedly connected to the frame and are symmetrically arranged. Two movable rods are slidably connected to the two limiting brackets and are symmetrically arranged. Two support springs are connected between each movable rod and the two limiting brackets. A sliding rod is slidably connected to each movable rod. A return spring is connected between each sliding rod and each movable rod. Three striking blocks are mounted on each movable rod.

[0011] Furthermore, the two racks will mesh with the two meshing gears respectively, and the striking block will contact the bottom of the support plate.

[0012] The beneficial effects are as follows: when the support block moves to contact the movable frame, the support block drives the movable frame and the support plate to move upward together, and the support plate pushes out the gypsum board blank in the forming mold, making it easier to remove the pressed gypsum board blank and improving the production efficiency of gypsum board.

[0013] Two rotating rollers roll and flatten the gypsum material in the forming mold, and roll the excess gypsum material in the forming mold into the collection groove, so that the gypsum material in the forming mold is more evenly distributed, which is conducive to the extrusion forming of gypsum board blanks and improves the production quality of gypsum boards.

[0014] Two scrapers repeatedly scrape away the plaster material adhering to the bottom of the press plate, ensuring that the bottom of the press plate remains clean before and after pressing the plasterboard blank. This reduces the amount of plaster material adhering to the bottom of the press plate and effectively improves the production quality of the plasterboard.

[0015] The striking block impacts the support plate several times, causing the gypsum material on the support plate to vibrate, reducing air bubbles and gaps in the gypsum material on the support plate, and further improving the production quality of the gypsum board. Attached Figure Description

Detailed Implementation

[0031] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Example 1 A molding device for gypsum board production, such as Figures 1-14 As shown, it includes a frame 1, fixed rods 2, electric push rods 3, mounting bracket 4, and molding mold 5. Four fixed rods 2 are installed on the frame 1, and two electric push rods 3 are installed on the frame 1. The two electric push rods 3 are symmetrically arranged, and the telescopic rods of the two electric push rods 3 extend out. The mounting bracket 4 is installed on both electric push rods 3. The mounting bracket 4 is slidably connected to the four fixed rods 2. The molding mold 5 is fixedly connected to the frame 1. The molding mold 5 is used for molding gypsum board, and the mounting bracket 4 is located above the molding mold 5.

[0033] It also includes a molding mechanism, which is installed on the frame 1. The molding mechanism includes a pressure plate 61, a support block 62, a movable frame 63, and a support plate 64. The pressure plate 61 is installed at the bottom of the mounting frame 4. The pressure plate 61 is used to press the gypsum material. The support block 62 is fixedly connected to the frame 1. The movable frame 63 is slidably connected to the frame 1. The support plate 64 is fixedly connected to the movable frame 63. The support plate 64 is located in the upper part of the molding mold 5 and is located below the pressure plate 61.

[0034] The movable frame 63 is provided with a sliding groove, and the support block 62 is located in the sliding groove of the movable frame 63. The support block 62 will disengage from the movable frame 63.

[0035] The operator activates two electric push rods 3. The telescopic rods of the two electric push rods 3 retract, causing the mounting frame 4 to move downwards. The mounting frame 4 then moves the pressure plate 61 and support block 62 downwards together. The movable frame 63 and support plate 64 move downwards under gravity. The support plate 64 moves to the bottom of the molding mold 5 and contacts the frame 1. The support block 62 disengages from the movable frame 63. The operator then stops the two electric push rods 3. The telescopic rods of the two electric push rods 3 stop retracting, and the mounting frame 4, pressure plate 61, and support block 62 stop moving downwards. Next, the operator pours plaster material onto the support plate 64. The operator then activates the two electric push rods 3 again. The telescopic rods of the two electric push rods 3 continue to retract, and the mounting frame 4, pressure plate 61, and support block 62 continue to move downwards. The pressure plate 61 moves to contact the gypsum material in the forming mold 5. The pressure plate 61, support plate 64, and forming mold 5 work together to compress the gypsum material into a gypsum board blank. Then, the operator controls the extension rod of the electric push rod 3 to extend. The extension rod of the electric push rod 3 drives the mounting frame 4, pressure plate 61, and support block 62 to move upward. The support block 62 moves to contact the movable frame 63. The support block 62 drives the movable frame 63 and support plate 64 to move upward together. Finally, the extension rod of the electric push rod 3 drives the mounting frame 4, pressure plate 61, support block 62, movable frame 63, and support plate 64 to move back to their original positions. The support plate 64 pushes out the gypsum board blank in the forming mold 5, making it easier to remove the pressed gypsum board blank and improving the production efficiency of gypsum board.

[0036] Example 2 Based on Example 1, such as Figures 4-11 As shown, it also includes a scraping mechanism, which is installed on the frame 1. The scraping mechanism includes a swing frame 71, a torsion spring 72, a rotating roller 73, and a collection trough 74. Two swing frames 71 are rotatably connected to the mounting frame 4. The two swing frames 71 are symmetrically arranged. Two torsion springs 72 are connected between each swing frame 71 and the mounting frame 4. A rotating roller 73 is rotatably connected to each swing frame 71. The rotating roller 73 is located between the pressure plate 61 and the support plate 64. The rotating roller 73 is used to roll the gypsum material in the forming mold 5. Two collection troughs 74 are fixedly connected to the frame 1. The two collection troughs 74 are symmetrically arranged and located on both sides of the forming mold 5. The collection troughs 74 are located below the rotating roller 73. The collection troughs 74 are used to collect excess gypsum material.

[0037] Mounting bracket 4 moves the swing brackets 71, torsion spring 72, and rotating roller 73 downwards together. The two swing brackets 71 move until they contact the top of the molding mold 5. Mounting bracket 4 then pushes the two swing brackets 71 further downwards. The molding mold 5 pushes the lower parts of the two swing brackets 71 to slide away from each other, and the two rotating rollers 73 slide away from each other. The torsion spring 72 is twisted, and the two rotating rollers 73 roll and flatten the plaster material inside the molding mold 5. The two rotating rollers 73 slide to both sides of the molding mold 5, and the two rotating rollers 73 flatten the molding mold. Excess gypsum material in mold 5 is rolled into the collection trough 74, making the gypsum material distribution in mold 5 more uniform. This is beneficial for the extrusion molding of gypsum board blanks and improves the production quality of gypsum board. After the gypsum board is pressed and molded, the mounting frame 4 drives the swing frame 71, torsion spring 72 and rotating roller 73 to move in opposite directions. The torsion spring 72 drives the two swing frames 71 to swing back to their original positions in opposite directions. The two swing frames 71 drive the rotating roller 73 to swing back to its original positions in opposite directions. Finally, the mounting frame 4 drives the swing frame 71, torsion spring 72 and rotating roller 73 to move upward together to their original positions.

[0038] Example 3 Based on Example 2, such as Figures 5-9 As shown, it also includes a cleaning mechanism, which is installed on the frame 1. The cleaning mechanism includes a limit rod 81, a sliding frame 82, a guide plate 83, and a scraper 84. Two limit rods 81 are fixedly connected to the mounting frame 4. The two limit rods 81 are symmetrically arranged. Two sliding frames 82 are slidably connected to the two limit rods 81. Two sets of guide plates 83 are installed on the frame 1. The two sets of guide plates 83 are symmetrically arranged. Each guide plate 83 is provided with an inclined groove. The two sliding frames 82 are slidably connected to the inclined grooves of the two sets of guide plates 83 respectively. Each sliding frame 82 is equipped with a scraper 84. Each scraper 84 is in contact with the bottom of the pressure plate 61. The scraper 84 is used to scrape off the plaster residue adhering to the bottom of the pressure plate 61.

[0039] The mounting frame 4 moves the two limiting rods 81 downwards together, and the two limiting rods 81 move the two sliding frames 82 and the scraper 84 downwards together. The two sets of guide plates 83 push the two sliding frames 82 to move away from each other. The two sliding frames 82 move the two scrapers 84 away from each other. The two sliding frames 82 and the two scrapers 84 move to both sides of the pressure plate 61. The two scrapers 84 disengage from the pressure plate 61. After the gypsum board is pressed and formed, the mounting frame 4 moves the two limiting rods 81 upwards, and the two sliding frames 82 move closer to each other. The two scrapers 84 move closer to each other and contact the bottom of the pressure plate 61. The mounting frame 4 moves the limiting frame 95, the sliding frames 82 and the scrapers 84 in the opposite direction to reset. The two scrapers 84 scrape off the gypsum material adhering to the bottom of the pressure plate 61, so that the bottom of the pressure plate 61 remains clean before and after the gypsum board blank is pressed. This reduces the amount of residual gypsum material adhering to the bottom of the pressure plate 61 and effectively improves the production quality of the gypsum board.

[0040] Example 4 Based on Example 3, such as Figures 5-9 As shown, it also includes a striking mechanism, which is mounted on the frame 1. The striking mechanism includes a rack 91, a rotating shaft 92, meshing gears 93, protrusions 94, a limiting bracket 95, a movable rod 96, a support spring 97, a sliding rod 98, a return spring 99, and a striking block 10. Two racks 91 are fixedly connected to the mounting bracket 4, and the two racks 91 are symmetrically arranged. A rotating shaft 92 is rotatably connected to the frame 1. Two meshing gears 93 are fixedly connected to the rotating shaft 92, and two protrusions 94 are fixedly connected to the rotating shaft 92, and the two protrusions 94 are symmetrically arranged. The frame 1 is fixedly connected to two limiting frames 95, which are symmetrically arranged. Two movable rods 96 are slidably connected to the two limiting frames 95. The two movable rods 96 are symmetrically arranged. Two support springs 97 are connected between each movable rod 96 and the two limiting frames 95. A sliding rod 98 is slidably connected to each movable rod 96. A return spring 99 is connected between each sliding rod 98 and the movable rod 96. Three striking blocks 10 are installed on each movable rod 96. The striking blocks 10 are used to strike the support plate 64.

[0041] The two racks 91 will mesh with the two meshing gears 93 respectively, and the striking block 10 will contact the bottom of the support plate 64.

[0042] Mounting bracket 4 moves the two racks 91 downwards a certain distance. After the plaster is poured in, mounting bracket 4 continues to move the two racks 91 downwards. The two racks 91 contact and mesh with the two meshing gears 93 respectively. The two racks 91 drive the two meshing gears 93 and the rotating shaft 92 to rotate. The rotating shaft 92 drives the two protrusions 94 to rotate. The two protrusions 94 push the two movable rods 96 and the two sliding rods 98 downwards respectively. The return spring 99 and the striking block 10 move downwards together. The support spring 97 is compressed. The striking block 10 disengages from the bottom of the support plate 64. The protrusions 94 rotate until they disengage from the sliding rods 98. The support spring 97 pushes the movable rods 96, sliding rods 98, return spring 99 and striking block 10 to quickly return to their original positions. The striking block 10 quickly returns to its original position and re-contacts the support plate 64. This process is repeated several times. The two racks 91 disengage from the two meshing gears 93 respectively. The striking block 10 then... 4. After several impacts, the gypsum material on the support plate 64 vibrates, reducing air bubbles and gaps in the gypsum material and further improving the production quality of the gypsum board. After the gypsum board blank is pressed, the mounting frame 4 drives the two racks 91 to move upward. The two racks 91 mesh with the two meshing gears 93 again. The two racks 91 drive the two meshing gears 93 to rotate in the opposite direction. The rotating shaft 92 and the two protrusions 94 rotate in the opposite direction. The two protrusions 94 push the two sliding rods 98 to move horizontally. The two return springs 99 are compressed, and the two protrusions 94 and the two sliding rods 98 are disengaged. The two return springs 99 push the two sliding rods 98 to return to their original positions. This process is repeated several times until the two racks 91 disengage from the two meshing gears 93. The meshing gears 93, rotating shaft 92 and protrusions 94 then stop rotating. The mounting frame 4 drives the two racks 91 to move in the opposite direction to their original positions.
