Description

Technical Field

[0001] The present invention relates to the field of gypsum board production and manufacturing, and more specifically, to a gypsum board production device and production process. Background Art

[0002] Gypsum board is made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, easy processing, good sound insulation, heat insulation and fire resistance. It is one of the new lightweight panels currently being developed. The production process of gypsum board mainly includes raw material collection, calcination, grinding, mixing, casting and solidification, cooling, cutting, drying, and finished products.

[0003] During the casting process, the gypsum board needs to use a mold to customize a certain size of hollow gypsum board according to the user's production needs;

[0004] The Chinese patent with the authorization announcement number CN207942542U specifically discloses a gypsum board processing mold, which pours the gypsum board slurry and pulls out the perforating rod after the slurry solidifies, and then drags the gypsum board out of the pouring slot through the support plate. The structure is simple and easy to operate; the side groove square steel and the side groove plate are respectively arranged one by one at the upper and lower parts of the pouring slot, which is convenient for processing the side groove notch on the gypsum board; the size of the pouring slot remains unchanged, and the size of the cast gypsum board is uniform and controllable;

[0005] Although this gypsum board processing mold can shorten the gypsum board processing period during specific use, it is difficult to demould the gypsum board because the gypsum board adheres to the inner wall of the mold after solidification. Usually, manual demoulding or demoulding with tools is required. After the gypsum board solidifies, the body is not dried and is relatively fragile. Manual demoulding by knocking and shaking can easily cause the gypsum board to break, which in turn causes the gypsum board casting to fail and produce defective products.

[0006] Therefore, a gypsum board production device and a production process are proposed. Summary of the invention

[0007] In view of the problems existing in the prior art, the purpose of the present invention is to provide a gypsum board production device and production process, which can be achieved.

[0014] Furthermore, slide rails are symmetrically distributed between the lower end surface of the main mold and the base, the main mold is slidably connected to the base via the slide rails, and a movable groove is provided in the middle of the upper end surface of the base.

[0026] (1) This solution pre-adjusts the displacement distance of the movable plates in the demolding mechanisms on both sides by adjusting the components. By pouring gypsum slurry with heat into the casting mold cavity, the heat is transferred to the airbag 2 through the movable plate, so that the ammonia gas expands due to the heat and pushes the movable plate to move.

[0028] (3) The present invention drives the smoothing plate and the moving block by designing a driving mechanism. On the one hand, when the smoothing plate is driven, the excess gypsum slurry in the casting mold cavity can be automatically removed to ensure that the produced gypsum boards have the same size, and the upper side of the gypsum boards can be trimmed by the smoothing plate when the molded gypsum boards are subsequently demolded. On the other hand, the driving mechanism drives the moving block to move in the moving groove, so that the demolding structure that is separated from the main mold and the auxiliary mold frame fixed by the moving block effectively improves the demolding efficiency and reduces the probability of defective products caused by damage to the gypsum board.

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0040] Embodiment 1:

[0041] See also Figures 1 to 8 , a gypsum board production device, comprising a main mold 1 with an opening on the left side, an auxiliary mold frame 4 of an L-shaped structure movably connected to the left side of the main mold 1, a base 3 movably connected to the lower end of the main mold 1, and the base 3 is fixedly connected to the auxiliary mold frame 4, a driving mechanism 5 is arranged on the left side of the auxiliary mold frame 4, a cooling mechanism 6 is arranged between the driving mechanism 5 and the auxiliary mold frame 4, partitions 2 are equidistantly distributed inside the main mold 1, the bottom of the partition 2 is fixed to the bottom end of the main mold 1, the internal space of the main mold 1 is divided into a plurality of casting cavities of the same size by the partition 2, and demoulding mechanisms are arranged on the front and rear sides of the partition 2;

[0042] The demoulding mechanism includes a mounting groove 23 provided on the front side of the partition 2, in which an airbag 22 is installed, and a movable plate 21 is arranged on the front end surface of the airbag 22, and the movable plate 21 is made of heat-conducting copper material. Ammonia is injected into the interior of the airbag 22, and a rubber sealing belt 24 is adhered and fixed around the movable plate 21 and the partition 2, and an adjustment component 25 is arranged in the middle of the upper end surface of the partition 2, and the displacement distance of the movable plate 21 in the demoulding mechanism on both sides is pre-adjusted by the adjustment component 25. By pouring gypsum slurry with heat into the casting cavity, the heat is thermally conducted to the airbag 22 through the movable plate 21, so that the ammonia expands due to the heat and pushes the movable plate 21 to move. After the gypsum slurry is cooled and formed, the ammonia is cooled and recovered, and the movable plate 21 returns to its original position. At this time, there is a demoulding gap between the formed gypsum board and the movable plate 21, so as to facilitate the subsequent better demoulding of the gypsum board.

[0043] By adopting the above technical solution, the displacement distance of the movable plate 21 in the demoulding mechanism on both sides is pre-adjusted by adjusting the component 25, and the heat-containing gypsum slurry is poured into the casting cavity. The heat is transferred to the air bag 22 through the movable plate 21, so that the ammonia expands due to the heat and pushes the movable plate 21 to move. After the gypsum slurry is cooled and formed, the ammonia is cooled and recovered, and the movable plate 21 returns to its original position. At this time, there is a demoulding gap between the formed gypsum board and the movable plate 21, so as to facilitate the subsequent better demoulding of the gypsum board.

[0044] like Figure 1 As shown, the demoulding mechanism also includes a movable hole 26 opened in the center of the airbag 22, and a telescopic rod 27 is movably connected in the movable hole 26. One end of the telescopic rod 27 is fixed to the movable plate 21, and the other end is fixed to the partition 2. The telescopic rod 27 includes a sleeve 272 and a rod body 271. One end of the rod body 271 extends into the sleeve 272 and cannot be detached. The sleeve 272 is fixed to the partition 2, and one end of the rod body 271 is fixed to the movable plate 21. The telescopic rod 27 assists the movable plate 21 to move smoothly and assists the movable plate 21 to reset after the gypsum board is cooled and formed.

[0045] By adopting the above technical solution, since the gypsum slurry itself has a certain temperature, when the gypsum slurry is poured into the casting mold cavity, the movable plates 21 on both sides of the partition 2 in the casting mold cavity contact the gypsum slurry and transfer the heat to the airbag 2 22 through the heat conduction of the movable plates 21. The ammonia in the airbag 22 expands under the action of the temperature. At this time, the movable plate 21 is squeezed by the expansion of the airbag 22 and moves slightly into the casting mold cavity, and cooperates with the rod body 271 to move in a guided manner inside the sleeve 272. At this time, there is a certain gap between the movable plate 21 and the partition 2. In order to prevent the gypsum slurry from entering between the movable plate 21 and the partition 2, a rubber sealing belt 24 is used for sealing here, and the rubber elastic characteristics of the rubber sealing belt 24 can meet the movable displacement distance of the movable plate 21 and meet the sealing conditions at the same time. Subsequently, as the gypsum slurry is cooled and formed, the ammonia is restored, and the airbag 2 22 also returns to its original position from the expanded state. At this time, there is a gap between the formed gypsum board and the movable plate 21, which is the demolding gap, which is convenient for the subsequent demolding of the gypsum board.

[0046] like Figure 1 As shown, an expansion groove 28 is opened inside the partition 2, and an expansion bag 29 is fixed inside the expansion groove 28. The expansion bag 29 is connected to the second airbag 22, and the wall thickness of the expansion bag 29 is twice that of the second airbag 22.

[0047] By adopting the above technical solution, the movable plate 21 is driven to move by the expansion of ammonia. Since ammonia continues to expand due to heat, in order to avoid the influence of excessive expansion of airbag 22 on the size of the formed gypsum board, the adjustment component 25 is designed to limit the movable plate 21 to be able to move only a specified distance, and the pressure of ammonia after continued expansion due to continuous heat cannot be released. In order to avoid the irregular expansion of airbag 22 affecting the movement of the movable plate 21, an expansion bag 29 is added. When airbag 22 cannot expand, the ammonia in airbag 22 flows into the expansion bag 29 to meet the pressure release process of airbag 22. Since the wall thickness of expansion bag 29 is greater than that of airbag 22, the phenomenon of expanding expansion bag 29 without meeting the expansion standard of airbag 22 will not occur.

[0048] like Figure 1 As shown, the adjustment component 25 includes a rotating groove 255 opened in the middle of the upper end surface of the partition 2, and a roller 252 is rotatably connected inside the rotating groove 255. A threaded hole is opened in the middle of the front and rear ends of the roller 252, and a cylinder 254 is threadedly connected in the threaded hole. The front end of the cylinder 254 is movably connected to a limiting rod 253, and the front end of the limiting rod 253 is fixed to the movable plate 21. The limiting rod 253 and the cylinder 254 cannot be separated, and the length of the threaded hole is greater than the length of the cylinder 254. The front end of the cylinder 254 is linearly slidably connected to the partition 2.

[0049] By adopting the above technical solution, when working, the user first adjusts the distance between two adjacent movable plates 21 according to the wall thickness of the cast gypsum board, thereby calculating the wall thickness of the gypsum board according to the subsequent displacement of the movable plate 21 to meet the demoulding of gypsum boards of different wall thicknesses. The user can open the sealing plate 251 sealed on the rotating groove 255, and then use the index finger to drive the roller 252 to rotate forward and reverse. Since the roller 252 is threadedly connected to the cylinder 254 through an internal threaded hole, and one end of the cylinder 254 is linearly slidably connected to the partition 2, it can be adjusted by rotating the roller 252, using the roller 252 to be threadedly connected to the cylinder 254 and slidably connected to the partition 2, the position of the cylinder 254 in the threaded hole can be adjusted, and then the displacement distance of the limit rod 253 movably connected to the cylinder 254 can be adjusted, thereby further limiting the displacement range of the movable plate 21 connected to the limit rod 253, and preventing the transitional displacement of the movable plate 21 from affecting the size of the gypsum board in the casting mold cavity.

[0050] like Figure 1 As shown, the driving mechanism 5 includes a connecting plate 12 fixed to the base 3, a motor 51 is fixed on the upper side of the connecting plate 12, a main transmission rod 57 is fixed to the output shaft of the motor 51, the external spiral transmission of the main transmission rod 57 is connected to the cooling mechanism 6, the outside of the main transmission rod 57 is located on the left side of the cooling mechanism 6 and is adjusted and fixed with a pulley 52 and a pulley 56, the middle part of the upper end surface of the auxiliary mold frame 4 is rotatably connected with a threaded rod 44, the end of the threaded rod 44 close to the motor 51 is also fixed with a pulley 52, a belt 53 is sleeved between the two pulleys 52, the external spiral transmission of the end of the threaded rod 44 is connected to a smoothing plate 42, the smoothing plate 42 is linearly slidably connected to the inner wall of the auxiliary mold frame 4, and a drainage hole 43 is opened on the outside of the auxiliary mold frame 4.

[0051] By adopting the above technical solution, after the gypsum slurry is cast into the casting cavity, there is excess gypsum slurry in the casting cavity, so it is necessary to remove the excess slurry to ensure the size of the gypsum board after molding. Therefore, the user can start the motor 51 to run, and the motor 51 drives the main transmission rod 57 to rotate. At this time, the threaded rod 44 connected by the pulley 52 and the belt 53 rotates synchronously, and the smoothing plate 42 connected to the threaded rod 44 in a spiral transmission moves inside the auxiliary mold frame 4. Since the threaded rod 44 is a reciprocating screw, the smoothing plate 42 will move repeatedly left and right in the auxiliary mold frame 4, and the excess gypsum slurry will be discharged through the drainage hole 43 for recycling. After the subsequent gypsum board is molded, the smoothing plate 42 can be driven to move, and the edge of the lower end surface of the smoothing plate 42 can be used to contact the upper end surface of the molded gypsum board to scrape and smooth the upper end surface of the gypsum board.

[0052] like Figure 1As shown, the interior of the movable groove 32 is rotatably connected with a threaded rod 55, and the exterior of the threaded rod 55 is also sleeved with a fixed pulley 56 at a position corresponding to the pulley 56, and a belt 54 is sleeved between the two pulleys 56, and a one-way bearing is arranged between the pulley 56 and the main transmission rod 57, and the inner ring of the one-way bearing is spirally connected to the main transmission rod 57, and a movable block 58 is fixed to the bottom of the main mold 1, and the movable block 58 is spirally connected to the threaded rod 55, and slide rails 31 are symmetrically distributed between the lower end surface of the main mold 1 and the base 3, and the main mold 1 is slidably connected to the base 3 through the slide rails 31, and a movable groove 32 is opened in the middle of the upper end surface of the base 3.

[0053] By adopting the above technical solution, after the gypsum board is cooled and formed, the motor 51 rotates in the opposite direction to drive the main transmission rod 57 to rotate. When the motor 51 rotates forward, since the pulley 56 is connected to the main transmission rod 57 through a one-way bearing, the pulley 56 will not rotate with the main transmission rod 57. When the motor 51 rotates in the opposite direction, the one-way bearing can be used to cooperate with the main transmission rod 57 through the pulley 56 and the belt to control the rotation of the threaded rod 55. Since the threaded rod 55 is a reciprocating screw, during subsequent resetting, the threaded rod 55 can be driven in only one direction to cooperate with the moving block 58, the moving groove 32 and the slide rail 31 to make the main mold 1 move on the base 3, thereby realizing the combined casting of the main mold 1 and the auxiliary mold frame 4, and the separation and demoulding.

[0054] like Figure 1 As shown, the cooling mechanism 6 includes an extrusion plate 61 which is spirally connected to the main transmission rod 57, an air bag 62 is glued and fixed between the extrusion plate 61 and the left side of the auxiliary mold frame 4, a plug-in copper tube 41 is fixed on the right side of the auxiliary mold frame 4 at an equidistant position corresponding to the casting mold cavity, the plug-in copper tube 41 is connected to the air bag 62, a plug-in hole 11 is opened on the right side of the main mold 1 at a position corresponding to the plug-in copper tube 41, and heat-conducting copper sheets 45 are distributed in a ring shape at equidistant intervals inside the plug-in copper tube 41, an air suction hole connected to the air bag 62 is opened on the outside of the extrusion plate 61, and a one-way air valve is arranged inside the air suction hole and in the plug-in copper tube 41.

[0055] By adopting the above technical scheme, after the gypsum slurry is poured into the casting mold cavity, it is necessary to cool the gypsum slurry as quickly as possible so that it can solidify and form as quickly as possible. Therefore, the motor 51 is started to drive the main transmission rod 57 to rotate. Since the connection area between the main transmission rod 57 and the extrusion plate 61 is a kind of reciprocating screw, the motor 51 rotates to control the extrusion plate 61 to repeatedly move left and right on the main transmission rod 57, thereby squeezing the airbag 62. The gas in the airbag 62 is input into the plug-in copper tube 41. Since the plug-in copper tube 41 and the heat-conducting copper sheet 45 are in the gypsum slurry, the heat of the gypsum slurry is absorbed and the gas is discharged through the right end of the plug-in copper tube 41. In this way, the gypsum slurry in the casting mold cavity is cooled and cooled. The airbag 62 absorbs external air through the suction hole to supplement the internal gas consumption. In order to prevent the extrusion plate 61 from rotating, a slide rail 31 is added to the right end of the extrusion plate 61 and the auxiliary mold frame 4 to limit its linear displacement.

[0056] A gypsum board production process comprises the following steps:

[0057] S1: The main mold 1 and the auxiliary mold frame 4 are combined and closed, and the gypsum slurry is poured into the casting mold cavity in the main mold 1 through the upper end of the auxiliary mold frame 4;

[0058] S2: The demoulding mechanism is used to shape the gypsum slurry in the casting mold cavity and automatically reserve the demoulding gap.

[0059] Since the gypsum slurry itself has a certain temperature, when the gypsum slurry is poured into the casting cavity, the movable plates 21 on both sides of the partition 2 in the casting cavity contact the gypsum slurry and transfer the heat to the airbag 2 22 through heat conduction of the movable plates 21. The ammonia in the airbag 22 expands under the action of the temperature. At this time, the movable plate 21 is squeezed by the expansion of the airbag 22 and moves slightly into the casting cavity, and cooperates with the rod body 271 to move in a guided manner inside the sleeve 272. At this time, there is a certain gap between the movable plate 21 and the partition 2. In order to prevent the gypsum slurry from entering between the movable plate 21 and the partition 2, a rubber sealing belt 24 is used for sealing here, and the rubber elasticity of the rubber sealing belt 24 can The movable plate 21 is moved to a movable displacement distance and the sealing condition is met at the same time. As the gypsum slurry is subsequently cooled and formed, the ammonia is restored, and the airbag 22 is also restored to its original position from the expanded state. The movable plate 21 is pulled to move and reset by the airbag 22. At this time, there is a gap between the formed gypsum board and the movable plate 21, and the gap is the demolding gap, which is convenient for the subsequent demolding of the gypsum board. The movable plate 21 is driven to move by the expansion of ammonia. Since ammonia continues to expand when heated, in order to avoid the influence of the excessive expansion of the airbag 22 on the size of the formed gypsum board, the adjustment component 25 is designed to limit the movable plate 21 to be able to move only a specified distance, and the ammonia continues to expand after being heated. The pressure cannot be released. In order to prevent the irregular expansion of the airbag 22 from affecting the movement of the movable plate 21, an expansion bag 29 is added. When the airbag 22 cannot expand, the ammonia in the airbag 22 flows into the expansion bag 29 to meet the pressure release process of the airbag 22. Since the wall thickness of the expansion bag 29 is greater than that of the airbag 22, the expansion bag 29 will not be expanded when the expansion standard of the airbag 22 is not met. When working, the user first adjusts the distance between the two adjacent movable plates 21 according to the wall thickness of the poured gypsum board, and then calculates the wall thickness of the gypsum board according to the subsequent displacement of the movable plate 21 to meet the demoulding of gypsum boards of different wall thicknesses. The user The sealing plate 251 sealed on the rotating groove 255 can be opened, and then the index finger drives the roller 252 to rotate forward and reverse. Since the roller 252 is threadedly connected to the cylinder 254 through the internal threaded hole, and one end of the cylinder 254 is linearly slidably connected to the partition 2, it can be adjusted by rotating the roller 252, using the roller 252 to be threadedly connected to the cylinder 254 and slidably connected to the partition 2, the position of the cylinder 254 in the threaded hole can be adjusted, and then the displacement distance of the limit rod 253 movably connected to the cylinder 254 can be adjusted, thereby further limiting the displacement range of the movable plate 21 connected to the limit rod 253, and preventing the transitional displacement of the movable plate 21 from affecting the size of the gypsum board in the casting mold cavity;

[0060] S3: The driving mechanism 5 drives the smoothing plate 42 to scrape the excess gypsum slurry on the upper end of the casting mold cavity to remove the excess gypsum slurry and assist in trimming the upper end surface after the gypsum slurry is formed. After the gypsum slurry is cast into the casting mold cavity, there is excess gypsum slurry in the casting mold cavity, so the excess slurry needs to be removed to ensure the size of the gypsum board after molding. Therefore, the user can start the motor 51 to run, and the motor 51 drives the main transmission rod 57 to rotate. At this time, the threaded connection connected by the pulley 52 and the belt 53 is driven. The rod 44 rotates synchronously, and the caressing plate 42 connected to the threaded rod 44 in a spiral transmission moves inside the auxiliary mold frame 4. Since the threaded rod 44 is a reciprocating screw, the caressing plate 42 moves back and forth repeatedly inside the auxiliary mold frame 4, and the excess gypsum slurry is discharged through the drainage hole 43 for recycling. After the subsequent gypsum board is formed, the caressing plate 42 can be driven to move, and the edge of the lower end surface of the caressing plate 42 can be used to contact the upper end surface of the formed gypsum board to scrape and smooth the upper end surface of the gypsum board.

[0061] S4: The driving mechanism 5 drives the cooling mechanism 6 to operate to cool and shape the gypsum slurry in the casting mold cavity, and the motor 51 is started to drive the main transmission rod 57 to rotate. Since the connection area between the main transmission rod 57 and the extrusion plate 61 is a kind of reciprocating screw, the motor 51 rotates to control the extrusion plate 61 to repeatedly move left and right on the main transmission rod 57, thereby squeezing the airbag 1 62, and the gas in the airbag 1 62 is input into the plug-in copper tube 41. Since the plug-in copper tube 41 and the heat-conducting copper sheet 45 are in the gypsum slurry, the heat of the gypsum slurry is absorbed, and the gas is discharged through the right end of the plug-in copper tube 41. In this way, the gypsum slurry in the casting mold cavity is cooled and cooled. The airbag 1 62 absorbs external air through the suction hole to supplement the internal gas consumption. In order to prevent the extrusion plate 61 from rotating, a slide rail 31 is added to the right end of the extrusion plate 61 and the auxiliary mold frame 4 to limit its linear displacement;

[0062] S5: After the gypsum is formed, the driving mechanism 5 drives the main mold 1 to move on the base 3 and disengage from the auxiliary mold frame 4, and cooperates with the demoulding mechanism to realize the demoulding of the main mold 1 and the gypsum board. After the gypsum board is cooled and formed, the motor 51 rotates in the opposite direction to drive the main transmission rod 57 to rotate. When the motor 51 rotates forward, since the pulley 2 56 is connected to the main transmission rod 57 through a one-way bearing, the pulley 2 56 will not rotate with the main transmission rod 57. When the motor 51 rotates in the opposite direction, it can cooperate with the main transmission rod 57 through the pulley 2 56 and the belt through the one-way bearing to control the rotation of the threaded rod 2 55. Since the threaded rod 2 55 is a reciprocating screw, during the subsequent resetting, the threaded rod 2 55 can be driven in only one direction to cooperate with the moving block 58, the moving groove 32 and the slide rail 31 to make the main mold 1 move on the base 3, so as to realize the combined casting of the main mold 1 and the auxiliary mold frame 4 and the separation and demoulding.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
