Abstract

This invention discloses a gypsum board edge leveling device, comprising an edge leveling component disposed above the gypsum board and capable of abutting against both sides of the gypsum board; an integrated frame fixedly connected to both ends of the edge leveling component; a drive mechanism disposed below the edge leveling component, with the actuating end of the drive mechanism fixedly connected to the center of the integrated frame; and a gear height adjustment component connected to the drive mechanism. This invention, by setting up a drive mechanism and a gear height adjustment component, and having them work together on the edge leveling component, uses the drive mechanism for primary position adjustment to adjust the edge leveling component to its approximate position, and then uses the gear height adjustment component for secondary position adjustment to more precisely adjust the position of the edge leveling component.

Description

Technical Field

[0001] This invention relates to the field of gypsum board production technology, specifically to a gypsum board edge leveling device. Background Technology

[0002] In actual production, paper-faced gypsum board often exhibits a phenomenon where the side facing paper curls up, causing a deviation in the verticality of the side edge.

[0003] To address this issue, a stainless steel triangular pressure iron with dimensions of 50*140*205* and a thickness of 5mm is currently suspended from the plasterboard on the production line. During production, this triangular pressure iron is lowered and pressed against the side of the plasterboard to be formed, thereby leveling the edge of the plasterboard.

[0004] However, in actual operation, the position of the triangular pressure iron is not precise enough, and the gap between the triangular pressure iron and the production line surface is often too large or too small.

[0005] If the gap between the bottom of the triangular pressure iron and the surface of the production line is too large, the protective paper on the edge of the gypsum board cannot be completely flattened after flowing through this gap, resulting in poor edge flattening effect.

[0006] If the gap between the triangular pressure iron and the production line surface is too small, the edge thickness of the gypsum board after molding will be less than the middle thickness, resulting in poor quality of the finished product. Summary of the Invention

[0007] The purpose of this invention is to provide a gypsum board edge leveling device to solve the technical problem in the prior art where the poor quality of gypsum board after molding is caused by the inaccurate falling position of the triangular pressure iron.

[0008] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0009] A gypsum board edge leveling device, comprising:

[0010] An edge leveling component is disposed above the gypsum board and can abut against the two sides of the gypsum board. The edge leveling component includes a support base tube and a shaped leveling plate. The two ends of the support base tube protrude from both sides of the gypsum board production line. The shaped leveling plate is disposed at the end of the support base tube. The bottom surface of the shaped leveling plate abuts against the top surface of the edge of the gypsum board to be formed for leveling.

[0011] The zigzag-shaped gypsum board includes a main part and wings. The wings are disposed on both sides of the main part, and the main part and the wings are integrally formed to form a zigzag shape. The main part movably overlaps the top surface of the end of the supporting base tube. There are movable gaps between the two sides of the zigzag-shaped gypsum board and the two sides of the supporting base tube. The bottom surface of the wings abuts against the edge of the gypsum board.

[0012] An integrated frame is fixedly connected to both ends of the edge leveling component. The integrated frame includes a support beam and support sides disposed on both sides of the support beam. The support beam is located below the gypsum board production line. One end of the support side is connected to the support beam, and the other end is fixedly connected to the edge leveling component.

[0013] A drive mechanism is provided below the edge leveling component. The working end of the drive mechanism is fixedly connected to the center of the support beam, and the working end of the drive mechanism is fixedly connected to both ends of the support base tube through the support beam. The drive mechanism enables the integrated frame and the edge leveling component to move as a whole in the vertical direction.

[0014] A gear height adjustment assembly, connected to the drive mechanism, is used to adjust the height of the drive mechanism in the vertical direction.

[0015] As a preferred technical solution of the present invention, a circular platform is provided in the middle of the support beam, and a frustum stabilizer is provided on the circular platform. The cross-section of the frustum stabilizer in the vertical direction is trapezoidal.

[0017] As a preferred technical solution of the present invention, the gear height adjustment assembly includes a mounting base, a sliding assembly, and a height adjustment component. The mounting base is fixedly installed below the edge leveling assembly. The driving mechanism is disposed on the mounting base through the sliding assembly. The height adjustment component is connected to the sliding assembly. The height adjustment component is used to drive the sliding assembly to slide on the mounting base to drive the driving mechanism to move in the vertical direction.

[0018] As a preferred technical solution of the present invention, the sliding component includes a strip-shaped groove formed on the top of the mounting base, a cover sleeve disposed inside the strip-shaped groove, and a connector connected to the cover sleeve. A slide rail is formed on the inner wall of the strip-shaped groove. One end of the connector is slidably connected to the slide rail, and the other end is mounted on the cover sleeve. The tail end of the drive mechanism is fixedly mounted inside the cover sleeve.

[0019] The height adjustment component includes a rotating gear and teeth formed on the outer surface of the cover sleeve. The rotating gear meshes with the teeth and is connected to the output end of a drive motor, which drives the rotating gear to rotate.

[0020] The height adjustment component drives the cover to slide longitudinally within the strip groove, thereby moving the drive mechanism.

[0021] As a preferred technical solution of the present invention, the gear height adjustment assembly further includes a first bevel gear and a second bevel gear. The first bevel gear is coaxially and fixedly connected to the rotating gear. The first bevel gear is meshed with the second bevel gear.

[0026] This invention incorporates a drive mechanism and a gear height adjustment component, which work together on an edge leveling component. The drive mechanism adjusts the edge leveling component to its approximate position initially, and then the gear height adjustment component performs a secondary adjustment to precisely position the edge leveling component. This ensures that the final position of the edge leveling component better meets the standards, thus effectively leveling the edges without crushing the edges of the gypsum board to be formed, thereby improving the production quality of the product.

[0035] 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.

[0036] like Figures 1 to 5 As shown, the present invention provides a gypsum board edge leveling device. In the actual production process, due to the unbalanced lateral wet expansion of the upper and lower protective papers on the edge of the gypsum board, the edge curls up, that is, the protective paper on the edge of the gypsum board curls up, which increases the scrap rate of gypsum board production.

[0037] Therefore, a flattening device is installed on the gypsum board production line to flatten the raised edges of the gypsum board using a flat plate, thereby improving product quality.

[0038] like Figure 1 As shown, this device includes an edge leveling component 1, which is positioned above the plasterboard and can abut against both sides of the plasterboard.

[0039] The integrated frame 2 is fixedly connected to both ends of the edge leveling component 1.

[0040] A drive mechanism 3 is disposed below the edge leveling component 1. The working end of the drive mechanism 3 is fixedly connected to the center of the integrated frame 2, and it enables the integrated frame 2 and the edge leveling component 1 to move as a whole in the vertical direction.

[0041] The gear height adjustment component is connected to the drive mechanism 3 and is used to adjust the height of the drive mechanism 3 in the vertical direction.

[0042] This device is installed above a normal gypsum board production line. Gypsum board production line 1 typically includes support legs, a line frame, roller sets, a conveyor belt, a facing paper laying device, etc. During the production process, the main workflow of the production line is as follows: first, the lower facing paper is laid on the conveyor belt of the production line; then, gypsum board slurry (a water-based fluid that will solidify with the upper and lower facing papers after subsequent molding) is poured onto the lower facing paper; finally, the upper facing paper is laid on the slurry.

[0043] The laying of the upper and lower facing papers and the pouring of the pulp are all operated by specialized equipment, and these devices are already mature in existing technology centers. In this example, these devices are included in production line 1.

[0044] Furthermore, the laying of the facing paper and the pouring of the pulp both occur during the moving process. That is, the conveyor belt moves continuously under the action of the rollers. After the lower facing paper is placed on the conveyor belt, as the conveyor belt continues to lengthen (the facing paper is rolled into a roll and placed above the production line; as the conveyor belt moves, the facing paper roll continuously rotates and lengthens, causing the facing paper to be continuously laid along the length of the conveyor belt), the pouring of the pulp is also a continuous process, until the lower facing paper is completely laid.

[0045] This device is installed after the top protective paper has been laid and the gypsum board has been initially formed. As the gypsum board moves along the production line, it is flattened by the edge leveling component.

[0046] A leveling device typically works by placing a flat surface above the gypsum board to be formed, creating a certain gap between this surface and the production line surface. This gap is usually equal to the thickness of the gypsum board. As the gypsum board moves downstream along the production line, its edges automatically touch the flat surface, thus achieving leveling.

[0047] The edge leveling component includes a support base tube 19 and a shaped leveling plate. The two ends of the support base tube 19 protrude from both sides of the gypsum board production line. The shaped leveling plate is set at the end of the support base tube 19. The bottom surface of the shaped leveling plate abuts against the top surface of the edge of the gypsum board to be formed for leveling. The working end of the drive mechanism 3 is fixedly connected to both ends of the support base tube 19.

[0048] This device mounts a geometrically shaped leveling plate for edge leveling on the support base tube 19, allowing it to be placed more stably on the edge of the gypsum board as it moves with the support base tube 19, thus pressing it firmly against the edge of the gypsum board and better leveling it.

[0049] Furthermore, the zigzag flat plate includes a main part 20 and wings 21. The wings 21 are located on both sides of the main part 20, and the main part 20 and the wings 21 are integrally formed to form a zigzag shape. The main part 20 is movably connected to the top surface of the end of the support base tube 19. There is a movable gap between the two sides of the zigzag flat plate and the two sides of the support base tube 19. The bottom surface of the wings 21 abuts against the edge of the gypsum board.

[0050] The edge of the wing 21 curves upwards at an angle to form a raised edge 22, and the angle between the raised edge 22 and the main body of the wing 21 is between 150° and 160°.

[0051] When large particles in the gypsum board slurry cause severe protrusions on the gypsum board surface (i.e., facing paper), if the shaped flat plate is set between the support base tubes 19 but there is no gap between them, when the wing 21 comes into contact with the protrusion, the surface of the facing paper will be scratched due to the interference of the protrusion and the immovability of the shaped flat plate itself, resulting in an increase in the scrap rate of the production process.

[0052] When there are large particles in the gypsum board slurry, the particles will cause the facing paper on the surface of the gypsum board to form protrusions. When the protruding facing paper comes into contact with the flat board, the wings 21 will squeeze the protrusions and make them sink into the slurry.

[0053] However, when larger particles encounter significant resistance in the slurry (such as when the slurry is highly viscous or when there is a hard object blocking the particles), the raised face paper may tear when it comes into rigid contact with the fixed wing 21.

[0054] Therefore, a wing 21 is provided in this device. When there are large particles forming protrusions inside the gypsum board, the gypsum board wing 4 first contacts the protrusion and presses it down, squeezing the protrusion downwards a certain distance. However, when the protrusion encounters great resistance and cannot move down in the slurry, the gypsum board will lift up, so that the protrusion is located below the wing.

[0055] During the subsequent movement of the gypsum board, the protrusions are pressed down again by the weight of the shaped slab 2, so that they are completely submerged in the slurry, thus completing the leveling work.

[0056] The raised edge 22 creates a bend in the wing 21, preventing the plasterboard from being punctured by the right angle of the wing 21 when it enters the wing 21. This ensures the stability of the device and helps improve the leveling quality of the product.

[0057] However, when the production line stops due to production completion or paper breakage, the edge leveling device will be moved upwards, and then lowered back down for leveling after production resumes.

[0058] This process is usually adjusted manually by production line staff, which can lead to improper adjustment, such as the leveling device being too low or too high. If the gap between the bottom of the gypsum board and the production line surface is too large, the protective paper on the edge of the gypsum board cannot be completely flattened after flowing through this gap, resulting in poor edge leveling.

[0059] If the gap between the gypsum board and the production line surface is too small, the edge thickness of the gypsum board after molding will be less than the middle thickness, resulting in poor quality of the finished product and unnecessary defective products.

[0060] Therefore, in this device, a drive mechanism 3 and a gear height adjustment component are also provided. The drive mechanism 3 is connected to the edge leveling component through the integrated frame 2. Then, the drive mechanism 3 drives the edge leveling component to move up or down, thereby adjusting the position of the edge leveling component.

[0061] The drive mechanism 3 can be a lifting cylinder, which is automatically operated by external control to control the position of the gear height adjustment component. Then, the gear height adjustment component controls the movement of the drive mechanism 3. At this time, the drive mechanism 3 drives the movement of the edge leveling device through the integrated frame 2, thereby achieving the function of secondary adjustment of the position of the edge leveling component.

[0062] The purpose of the gear height adjustment component is to enable more precise positional movement. By adjusting individual teeth of the gear, it can make secondary movements more precise than primary movements.

[0063] Among them, such as Figure 2 As shown, the integrated frame 2 includes a support beam 4 and support edges 5 disposed on both sides of the support beam 4. The support beam 4 is located below the gypsum board production line. One end of the support edge 5 is connected to the support beam 4, and the other end is fixedly connected to the edge leveling component 1. In this device, the integrated frame, the circular stabilizing platform, and the edge leveling component can be made of lightweight materials, resulting in a lighter overall weight, which facilitates subsequent operation.

[0064] Furthermore, the diagram does not show the complete production line for gypsum board. In actual setup, the edge leveling components directly contact the gypsum board, which is placed on the conveyor belt of the gypsum board production line.

[0065] The function of the integrated frame 2 is to connect the two ends of the support base tube 19 to form a whole, so as to keep them at the same height and prevent uneven flatness on both sides during normal use.

[0066] If the integrated frame 2 is not used, and the two ends of the support base tube 19 are connected and supported by the drive mechanism 3 respectively, there is a possibility of uneven tilting due to the different strokes of the drive mechanism 3. Especially after long-term use, the working end of the drive mechanism 3 may wear or shake, causing the two drive mechanisms 3 to rise to different positions, resulting in uneven positions of the two shaped flat plates and thus poor leveling effect.

[0067] Therefore, in this device, the two ends of the support base tube 19 are connected by the integrated frame 2 to form a whole, and a drive mechanism 3 is used to connect and push it, so that it can reach the same height.

[0068] Furthermore, a circular platform 6 is provided in the middle of the support beam 4, and a frustum stabilizer 7 is provided on the circular platform 6. The cross-section of the frustum stabilizer 7 in the vertical direction is trapezoidal.

[0069] The large bottom surface of the frustum stabilizer 7 is connected to the circular platform 6, and the small bottom surface of the frustum stabilizer 7 is connected to the working end of the drive mechanism 3.

[0070] By using the frustum stabilizer 7 to connect the working end of the drive mechanism 3 to the integrated frame 2, the driving of the drive mechanism 3 can be made more stable. Through its larger connection area with the integrated frame 2, the force transmission can be wider, resulting in a better driving effect.

[0071] As shown in Figure 2, the gear height adjustment assembly includes a mounting base 8, a sliding assembly, and a height adjustment assembly. The mounting base 8 is fixedly installed below the side leveling assembly 1. The drive mechanism 3 is set on the mounting base 8 through the sliding assembly. The height adjustment assembly is connected to the sliding assembly. The height adjustment assembly is used to drive the sliding assembly to slide on the mounting base 8 so as to drive the drive mechanism 3 to move in the vertical direction.

[0072] The sliding assembly includes a strip-shaped groove 9 formed on the top of the mounting base 8, a cover sleeve 10 disposed inside the strip-shaped groove 9, and a connector 11 connected to the cover sleeve 10. A slide rail 12 is formed on the inner wall of the strip-shaped groove 9. One end of the connector 11 is slidably connected to the slide rail 12, and the other end is mounted on the cover sleeve 10. The tail end of the drive mechanism 3 is fixedly mounted inside the cover sleeve 10.

[0073] The height adjustment assembly includes a rotating gear 14 and teeth 13 formed on the outer surface of the cover sleeve 10. The rotating gear 14 is meshed with the teeth 13. The rotating gear 14 is connected to the output end of the drive motor, and the drive motor drives the rotating gear 14 to rotate.

[0074] The height adjustment component drives the drive mechanism 3 to move by sliding the drive cover 10 longitudinally within the strip groove 9.

[0075] In this device, in addition to using the lifting function of the drive mechanism 3 itself to move the edge leveling component, a gear height adjustment component is also used to adjust the position of the edge leveling component a second time. The purpose is to more accurately fix the position of the lower edge leveling component.

[0076] In the gear height adjustment assembly, a rotary motor can be installed to drive the rotation of the rotary gear 14. When the rotary gear 14 rotates, it causes the cover sleeve 10, which meshes with it, to slide up and down within the strip groove 9, thereby driving the drive mechanism 3 to move up and down. This achieves secondary adjustment.

[0077] Furthermore, such as Figure 4 As shown, the gear height adjustment assembly also includes a first bevel gear 15 and a second bevel gear 16. The first bevel gear 15 is coaxially and fixedly connected to the rotating gear 14. The first bevel gear 15 is meshed with the second bevel gear 16. An extension rod 17 is coaxially and fixedly provided on one side surface of the second bevel gear 16. The extension rod 17 extends to the side of the gypsum board production line and is connected to a rotating handle.

[0078] The first bevel gear 15 and the second bevel gear 16 allow the rotating gear 14 to be rotated manually, thereby driving the movement of the cover sleeve 10. The second bevel gear 16 is extended to one side of the production line via an extension rod 17, allowing workers located on the side of the production line to manually drive it, thus enabling more flexible secondary adjustments.

[0079] like Figure 4 As shown, multiple vertically extending stabilizing support rods 18 are also provided on the top surface of the mounting base 8. The multiple stabilizing support rods 18 are arranged in a circular array with the longitudinal central axis of the frustum-shaped stabilizing seat 7 as the rotation center line. One end of the stabilizing support rod 18 is installed on the top surface of the mounting base 8, and the other end is set on the side surface of the frustum-shaped stabilizing seat 7. The stabilizing support rod 18 is a telescopic support rod.

[0080] The function of the stabilizing support rod 18 is to enable the edge leveling component to be connected more stably to the drive mechanism 3. It needs to be a telescopic support rod, which can be set to be made of two support rods sleeved together, or it can be a pneumatic rod, which can stabilize the overall device while also playing a telescopic role.

Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
