Description

Technical Field

[0001] This invention relates to the field of gypsum board production equipment technology, specifically to a gypsum board wedge edge forming device with adjustable depth. Background Technology

[0002] During the production of gypsum board, in accordance with the national standard GBT9775-2008, wedge-shaped edges need to be added to both sides of the front of the gypsum board. The depth and width of the wedge-shaped edges need to be made to the corresponding dimensions according to the enterprise standard requirements.

[0003] In related technologies, the wedge-shaped edge of paper-faced gypsum board is formed by secondary shaping via a wedge belt during the conveying process after the gypsum board is extruded and formed on the forming table, and then leveled by a leveling structure to obtain a more standardized wedge-shaped edge.

[0004] However, obtaining wedge-shaped gypsum board through two or three shaping processes is cumbersome and not conducive to improving production efficiency. Although existing technologies have solved the above problems to some extent, the thickness and position of the wedge-shaped belt are fixed, making it difficult to adjust the forming depth and width of the wedge-shaped edge of the gypsum board. Furthermore, during the secondary shaping process, due to the softness of the board, the edges are prone to warping, bending, and rounding, resulting in quality defects in the finished product that cannot meet customer requirements. Therefore, there is an urgent need to solve this problem. Summary of the Invention

[0005] The purpose of this invention is to provide a depth-adjustable gypsum board wedge edge forming device to solve the technical problems in the prior art where step-by-step gypsum board forming and wedge edge forming are not conducive to improving efficiency, and the depth and width of the wedge edge obtained by secondary forming are difficult to adjust.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0007] A depth-adjustable gypsum board wedge edge forming device includes a forming base mounted above a gypsum board conveying mechanism and an extrusion plate mounted on the forming base. Correction edges are provided on both sides of the extrusion plate, and a wedge edge forming mechanism is provided at the bottom of the extrusion plate. The wedge edge forming mechanism is provided on both sides of the conveying mechanism.

[0008] The forming base controls the extrusion plate to move downwards to extrude and shape the gypsum board. At the same time, the wedge-shaped edge forming mechanism bevels the edge of the gypsum board to form a wedge-shaped edge. When the extrusion plate presses the gypsum board downwards, it cooperates with the wedge-shaped edge forming mechanism on the bottom side to extrude the gypsum board to prevent the edge of the gypsum board from warping. The correcting edge corrects and flattens the formed wedge-shaped edge to avoid rounding the edge.

[0009] As a preferred embodiment of the present invention, the molding base includes a molding platform support and a lifting drive unit installed on the molding platform support. The extrusion plate is disposed at the bottom of the lifting drive unit, and the extrusion plate is lifted and lowered under the drive of the lifting drive unit to extrude and flatten the gypsum board.

[0010] The wedge-shaped edge forming mechanism includes a chamfering section and a shifting component for driving the chamfering section to move. The shifting component drives the chamfering section to move in order to adjust the depth of the chamfering section in forming the wedge-shaped edge of the gypsum board.

[0011] The extrusion plate presses the sheet material downwards, while the chamfering part extrudes and plastically shapes the two sides of the sheet material to form a wedge-shaped edge. When the extrusion plate and the chamfering part work together to extrude the sheet material, warping at the wedge-shaped edge is avoided.

[0012] As a preferred embodiment of the present invention, the corrected edge includes a flat plate and wedge rollers installed on both sides of the conveying mechanism. The wedge rollers are fitted to the wedge-shaped edge of the gypsum board. The flat plate is disposed above the edge of the board and the ends of the flat plate are fixedly connected to the wedge rollers. The wedge rollers and the flat plate cooperate to fit the board and correct the wedge-shaped edge.

[0013] In a preferred embodiment of the present invention, the displacement assembly includes a mounting base, and the chamfered portion includes a wedge plate mounted on the mounting base and an angle-adjusting power rod. The wedge plate can rotate under the drive of the angle-adjusting power rod to change the tilt angle of the wedge plate, thereby adjusting the depth or width of the wedge edge of the gypsum board.

[0014] In a preferred embodiment of the present invention, the extrusion platform includes a lifting rod and an extrusion plate disposed at the bottom of the lifting rod. The lifting drive unit drives the lifting rod and the extrusion plate to move up and down as a whole through a fixing frame. The fixing frame is installed on the top of the lifting rod.

[0015] As a preferred embodiment of the present invention, a telescopic part and a vertical edge plate are provided on the hoisting rod. The shaping length of the vertical edge plate on the side of the gypsum board is adjusted by the telescopic part. The vertical edge plate flattens the edge of the gypsum board, and the sum of the shaping length of the vertical edge plate and the depth of the wedge edge is equal to the thickness of the gypsum board.

[0016] As a preferred embodiment of the present invention, the longitudinal section shape of the extrusion plate is set to trapezoidal, and the extrusion plate, the wedge plate and the vertical edge plate cooperate with each other to extrude the plate to form the gypsum board and the wedge edge on the gypsum board in one step.

[0017] In a preferred embodiment of the present invention, a lifting groove is provided on the lifting rod, and a plate groove is provided on the side of the opening of the lifting groove. The telescopic part is installed in the lifting groove, and the vertical side plate is installed at the bottom of the telescopic part. The telescopic part retracts into the lifting groove, and the vertical side plate is stored in the plate groove.

[0018] As a preferred embodiment of the present invention, a driving member for driving the mounting base to move is provided at the bottom of the mounting base. The driving member drives the mounting base and the chamfered edge portion to move in the vertical direction as a whole. The depth of the wedge edge is adjusted by changing the position of the chamfered edge portion in the vertical direction.

[0019] As a preferred embodiment of the present invention, a support frame is provided at the bottom of the wedge-shaped edge forming mechanism, and the two sides of the wedge-shaped edge forming mechanism are mounted on the support frame. The driving component is mounted on the support frame through a telescopic shaft, and the horizontal position of the wedge plate is adjusted by telescopic adjustment through the telescopic shaft.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] This invention improves production efficiency by setting a forming base and an extrusion plate at the top of the gypsum board conveying mechanism, and setting a correction edge and a wedge edge forming mechanism on both sides and the bottom of the extrusion plate.

[0033] 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.

[0034] This invention relates to the field of gypsum board production technology, specifically to a gypsum board forming system. By setting up a forming table, an extrusion table, a wedge-shaped edge forming mechanism, and a trimming edge, the system simultaneously extrudes and shapes the gypsum board, thereby improving efficiency.

[0035] like Figure 1 and Figure 2 As shown, the present invention provides a depth-adjustable gypsum board wedge edge forming device, including a forming base 1 mounted above a gypsum board conveying mechanism and an extrusion plate 2 mounted on the forming base 1. Correction edges 3 are provided on both sides of the extrusion plate 2, and a wedge edge forming mechanism 4 is provided at the bottom of the extrusion plate 2. The wedge edge forming mechanism 4 is provided on both sides of the conveying mechanism 8.

[0036] The forming base 1 controls the extrusion plate 2 to move downward to extrude and shape the gypsum board. At the same time, the wedge-shaped edge forming mechanism 4 bevels the edge of the gypsum board to form a wedge-shaped edge. When the extrusion plate 2 extrudes the gypsum board downward, it cooperates with the wedge-shaped edge forming mechanism 4 on the bottom side to extrude the gypsum board to avoid the edge of the gypsum board from warping. The edge correction 3 corrects and flattens the formed wedge-shaped edge to avoid the edge from warping.

[0037] While the extrusion plate 2 extrudes the gypsum board downwards to flatten and shape it, the wedge-shaped edge forming mechanism 4 and the correction edge part 3 on both sides beveling and forming wedge-shaped edges on the gypsum board. The board forming and wedge-shaped edge forming are integrated and formed in one step, eliminating the need for secondary shaping and adjustment of the gypsum board, thus improving production efficiency. After the gypsum board is formed, the correction edge part 3 on both sides can fix and consolidate the wedge-shaped edge shape of the board, maintaining the wedge-shaped edge state during forming and preventing the gypsum board from collapsing and deforming due to its wet state during transportation.

[0038] Specifically, the molding base 1 includes a molding platform support 11 and a lifting drive unit 12 installed on the molding platform support 11. The extrusion plate is located at the bottom of the lifting drive unit 12. The extrusion plate 2 is lifted and lowered by the lifting drive unit 12 to extrude and flatten the gypsum board.

[0039] The lifting drive unit 12 of the forming base 1 is electrically connected to the control system of the gypsum board production line and is controlled by the control system. The control system controls the lifting drive unit 12 to drive the extrusion table 2 to move up and down to extrude and form the board.

[0040] The wedge forming mechanism 4 includes a chamfering part 41 and a shifting component 42 for driving the chamfering part 41 to move. The shifting component 42 drives the chamfering part 41 to move to adjust the depth of the chamfering part in forming the wedge edge of the gypsum board. The shifting component 42 and the chamfering part 41 of the wedge forming mechanism 4 are electrically connected to the control system and are controlled by the control system.

[0041] The extrusion plate 2 presses the sheet material downwards, while the chamfered part 41 extrudes and plasticizes the two sides of the sheet material to form a wedge-shaped edge. When the extrusion plate 2 and the chamfered part 41 work together to extrude the sheet material, warping at the wedge-shaped edge is avoided.

[0042] In related technologies, gypsum board is shaped into wedges through secondary shaping. The gypsum board passes through wedge belts on both sides, forming wedges on both sides. However, since there is no limiting shaping above the wedges, the lower wedges are easily formed, causing the edges of the gypsum board to curl upwards, which can easily lead to breakage of the gypsum board in subsequent production processes.

[0043] In this embodiment, the forming of the gypsum board and the forming of the wedge edge are carried out simultaneously. The extrusion plate 2 presses downward, and the chamfered edges 41 on both sides of the board simultaneously press the two sides of the board. The two extrusions limit and support each other, preventing the gypsum board from warping.

[0044] After the gypsum board body and wedge edges are formed, the gypsum board is corrected and shaped by edge correction 3 to maintain the wedge edge state of the gypsum board during transportation; specifically, such as Figure 5 As shown, the corrected edge 3 includes a flat plate 32 and wedge rollers 31 installed on both sides of the conveying mechanism. The wedge rollers 31 fit the wedge-shaped edge of the gypsum board. The flat plate 32 is set above the edge of the board and the two ends of the flat plate 32 are fixedly connected to the wedge rollers 31. The wedge rollers 31 and the flat plate 32 cooperate to fit the board and correct the wedge-shaped edge to maintain its state, preventing the wedge-shaped edge of the gypsum board from collapsing and deforming, which would cause the gypsum board to have rounded or bent edges.

[0045] In detail, such as Figure 4 As shown, the shifting assembly 42 includes a mounting base 421, and the chamfered portion 41 includes a wedge plate 411 mounted on the mounting base 421 and an angle adjustment power rod 412. The wedge plate 411 can rotate under the drive of the angle adjustment power rod 412 to change the tilt angle of the wedge plate 411, thereby adjusting the depth or width of the wedge edge of the gypsum board.

[0046] The bottom of the wedge plate 411 is rotatably connected to the mounting base 421 at the bottom. There are many ways to rotatably connect it, such as by hinge. The angle adjustment power rod 412 acts as a power rod to drive the wedge plate 411 to rotate. The angle adjustment power rod 412 adopts a rotation drive shaft, such as a lifting rod. Adjusting the tilt angle of the wedge plate 411 can adjust the width of the wedge edge formed by the wedge plate 411 at the edge of the gypsum board. The displacement component 42 drives the wedge plate 411 and the angle adjustment power rod 412 to move up and down as a whole, changing the position of the wedge edge formed at the edge of the gypsum board, thereby changing the depth of the wedge edge.

[0047] A drive component 422 for moving the mounting base 421 is provided at the bottom of the mounting base 421. The drive component 422 is configured as a cylinder piston, a lifting mechanism, or other forms. The drive component 422 drives the mounting base 421 and the chamfered edge 41 to move vertically as a whole. The depth of the wedge edge is adjusted by changing the position of the chamfered edge 41 in the vertical direction.

[0048] A support frame 5 is provided at the bottom of the wedge-shaped edge forming mechanism 4. The wedge-shaped edge forming mechanism 4 is mounted on the support frame 5 on both sides. The drive component 422 is mounted on the support frame 5 through the telescopic shaft 6. The horizontal position of the wedge plate 411 is adjusted by telescopically extending and retracting the telescopic shaft 6. Changing the position of the wedge-shaped edge forming mechanism 4 can adjust the contact position between the wedge plate 411 and the edge of the gypsum board, thereby changing the width and depth of the wedge-shaped edge of the gypsum board 7.

[0049] The extrusion platform 2 includes a lifting rod 21 and an extrusion plate 22. The extrusion plate 22 is located at the bottom of the lifting rod 21. The lifting drive unit 12 drives the lifting rod 21 and the extrusion plate 22 to move up and down as a whole through the fixing frame 23. The fixing frame 23 is installed on the top of the lifting rod 21.

[0050] In order not to affect the normal transportation and forming process of gypsum board, a telescopic part 24 and a vertical edge plate 25 are provided on the hoisting rod 21. The shaping length of the vertical edge plate 25 on the side of the gypsum board is adjusted by the telescopic part 24. The vertical edge plate 25 flattens the edge of the gypsum board.

[0051] In detail, such as Figure 3 As shown, a lifting groove 211 is provided on the lifting rod 21, and a plate groove 212 is provided on the side of the groove opening of the lifting groove 211. The telescopic part 24 is installed in the lifting groove 211, and the upright side plate 25 is installed at the bottom of the telescopic part 24. The telescopic part 24 retracts into the lifting groove 211, and the upright side plate 25 is stored in the plate groove 212.

[0052] Furthermore, the sum of the shaping length of the upright edge plate 25 and the depth of the wedge edge is equal to the thickness of the gypsum board. Especially when the depth of the wedge edge is less than the thickness of the gypsum board, that is, when the wedge edge of the gypsum board is multi-faceted, it is necessary to use the upright edge plate 25 to level the thick side wall of the gypsum board to avoid rounding the edge and thus ensure the edge beveling quality.

[0053] The longitudinal section of the extrusion plate 22 is set to a trapezoidal shape. The bottom edge of the extrusion plate 22 is longer so as to completely cover the width of the gypsum board 7, so as to better provide upper limiting support for the wedge plates 411 on both sides when they are working. The extrusion plate 22, the wedge plates 411 and the vertical edge plate 25 cooperate with each other to extrude the gypsum board and the wedge edges on the gypsum board in one step.

[0054] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. 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.
