Description

Technical Field

[0001] This invention relates to the field of sheet manufacturing and processing, specifically to a pressing and laminating equipment and process for a magnesium oxide board composite layer. Background Technology

[0002] Magnesium oxide board possesses superior physical properties such as high temperature resistance and flame retardancy, sound absorption and shock absorption, waterproofing and moisture resistance, insect resistance, lightweight and corrosion resistance, colorless, odorless and pollution-free, high strength, toughness, and the ability to be sawed, nailed, and glued. It meets the national Class A fire-resistant decoration standards, making it an ideal substrate for interior and exterior decoration. However, due to its rough surface, magnesium oxide board lacks decorative effect and can only be used as a base material for walls, requiring the entire board to be installed before applying a decorative surface. In actual construction, this method of applying the decorative surface after installation results in poor integrity between the surface layer and the base layer, generally exhibiting low bonding strength with the substrate. After a period of use, the decorative surface may separate from the substrate, leading to undesirable conditions such as bulging and cracking of the wall. Furthermore, compared to integrated finished decorative panels, this method of applying the decorative surface after installation has a longer construction period, higher cost, and is less energy-efficient and environmentally friendly. Therefore, a method has emerged on the market where magnesium oxide board and decorative panels are first pressed together to form a composite board, which is then installed on the wall to solve the problem of uneven bonding between the magnesium oxide board and the decorative panel.

[0003] However, existing composite pressing methods for magnesium oxide boards lack a mechanism for feeding the magnesium oxide boards and decorative panels one by one. This results in a significant waste of time between composite pressing steps, where the magnesium oxide boards and decorative panels need to be placed, stacked, and aligned one by one to facilitate hot pressing of the composite board. This numerous preliminary steps can affect the efficiency of hot pressing in actual use. Summary of the Invention

[0004] The purpose of this invention is to provide a pressing and laminating device and its laminating process for magnesium oxide board composite layers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0009] A placement plate is disposed inside the device box and is used to support the magnesium oxide board and the decorative panel. The device box is also provided with a third drive assembly for driving the placement plate to move.

[0010] Preferably, the third drive assembly includes a first motor installed inside the device housing, and the output end of the first motor is connected to a first gear via a rotating rod. The third drive assembly also includes a first lead screw rotatably connected to the inner side wall of the device housing. A second gear meshing with the first gear is sleeved at the middle position of the first lead screw. Two first sliders are also threaded onto the first lead screw, and the tops of the two first sliders are connected to the bottom of the placement plate.

[0011] Preferably, a cylinder is installed at the center of the top of the device box, and the output end of the cylinder is connected to an upper pressure plate.

[0012] Preferably, both the placement plate and the upper pressure plate are provided with heating wires inside, and the heating wires are distributed in a serpentine structure.

[0013] Preferably, both the first drive assembly and the second drive assembly include a connecting plate disposed on the side of the device box. The bottom of the connecting plate is connected to a second lead screw extending into the device box. A second slider is threaded onto the second lead screw. The bottom of the second slider is connected to a first actuating block or a second actuating block. A second motor is also installed at the bottom of the connecting plate, and the output end of the second motor is connected to one end of the second lead screw.

[0014] Preferably, the first drive assembly and the second drive assembly each have two second lead screws, and the two second lead screws are connected by a transmission assembly.

[0015] Preferably, the transmission assembly includes transmission wheels sleeved on two second lead screws, and the two transmission wheels are connected by a transmission belt.

[0016] Preferably, the placement plate has an internal cavity, and the bottom of the cavity is connected to two rotating shafts that extend to the bottom of the placement plate. A cam is fitted on the outside of each of the two rotating shafts. The top of the placement plate has clearance holes on both sides that communicate with the cavity. The two sides inside the cavity are hinged with clamps that pass through the clearance holes by pins. A third spring is provided on both sides of the inner wall of the cavity, and the other end of the third spring is connected to the clamp. A third gear is provided at the bottom of each of the two rotating shafts. A rack that meshes with the third gear is provided on the inner wall of the device box.

[0017] Preferably, both the first and second storage boxes are provided with a top plate, and the bottom of the top plate is provided with casters.

[0018] This invention also provides a composite process for a magnesium oxide board composite layer, comprising the following steps:

[0019] Step 1: Dry the magnesium oxide board substrate to remove moisture, and then sand one or both sides of the dried magnesium oxide board substrate to smooth it and remove dust.

[0020] Step 2: Apply a thermosetting resin film to the surface of the magnesium oxide board that has been sanded smooth in Step 1; then apply a thermosetting resin film to the underside of the decorative panel as well.

[0021] Step 3: Place the covered magnesium oxide board from Step 2 into the first storage box, and place the covered decorative panel into the second storage box.

[0022] Step 4: Place the magnesium oxide board inside the first storage box and the decorative panel inside the second storage box into the device box one by one, and then heat-press them together.

[0023] Step 5: Packaging yields the finished composite board.

[0024] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0025] 1. The first or second drive mechanism can push the top layer of magnesium oxide board or decorative panel into the device box for composite hot pressing. Since both magnesium oxide board and decorative panel have a certain weight, when too many magnesium oxide board or decorative panel are stacked, the first spring will be compressed. When the number of magnesium oxide board or decorative panel gradually decreases, the first spring gradually recovers its deformation, which can make the magnesium oxide board or decorative panel at the highest point. The lower layer of magnesium oxide board or decorative panel will be automatically replenished, ensuring the continuity of material feeding.

[0026] 2. By driving the second drive component on the second storage box, the second toggle block moves the decorative panel toward the placement board, thereby allowing the topmost decorative panel to move onto the placement board; the combination of the two allows the magnesium oxide board and the decorative panel to be stacked on top of each other, and the thermosetting resin film on the upper part of the magnesium oxide board and the thermosetting resin film on the lower part of the decorative panel can overlap each other, ensuring the adhesion between the magnesium oxide board and the decorative panel and achieving a better adhesive effect;

[0027] 3. When hot pressing is required between the magnesium oxide board and the decorative panel, the second drive component moves the placement plate laterally to the center of the device box, so that the magnesium oxide board and the decorative panel are aligned with the upper pressure plate. At this time, the drive cylinder lowers the upper pressure plate to contact the top of the decorative panel. The heating wires inside the upper pressure plate and the placement plate can melt the thermosetting resin film, thereby enabling the magnesium oxide board and the decorative panel to bond together, resulting in a better composite effect.

[0040] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0041] Please see Figures 1-8 A pressing and laminating device for a magnesium oxide board composite layer includes a device box 1, and further includes:

[0042] The storage assembly includes a first storage box 2 and a second storage box 3. The first storage box 2 is located on the left side of the device box 1, and the second storage box 3 is located on the right side of the device box 1. A through hole is provided at the connection between the first storage box 2 and the device box 1, and a through hole is also provided at the connection between the second storage box 3 and the device box 1. A first spring 4 is provided at the inner bottom of the first storage box 2, and a first sliding plate 5 is connected to the top of the first spring 4. The outer side of the first sliding plate 5 is in contact with the inner sidewall of the first storage box 2. Several magnesium oxide boards 6 are stacked on the top of the first sliding plate 5 along the height direction of the first storage box 2. A second spring 8 is provided at the inner bottom of the second storage box 3, and a first sliding plate 6 is connected to the top of the second spring 3. The second slide plate 9 is attached to the inner wall of the first storage box 2. Several decorative panels 10 are stacked on the top of the second slide plate 9 along the height direction of the second storage box 3. The top of the magnesium oxide board 6 and the bottom of the decorative panels 10 are both covered with thermosetting resin film 7. Since the magnesium oxide board 6 and the decorative panels 10 have a certain weight, when too many magnesium oxide boards 6 or decorative panels 10 are stacked, the first spring 4 will be compressed. When the number of magnesium oxide boards 6 or decorative panels 10 gradually decreases, the first spring 4 gradually recovers its deformation, so that the magnesium oxide boards 6 or decorative panels 10 are at the highest point. The lower layer of magnesium oxide boards 6 or decorative panels 10 will be automatically replenished to ensure the continuity of material feeding.

[0043] The actuating mechanism includes a first actuating block 11 disposed above the first storage box 2 and a second actuating block 12 disposed above the second storage box 3. A first driving assembly 13 for driving the first actuating block 11 to move is disposed above the first storage box 2, and a second driving assembly 14 for driving the second actuating block 12 to move is disposed above the second storage box 3. The first driving mechanism or the second driving mechanism can push the uppermost magnesium oxide board 6 or decorative panel 10 into the interior of the device box 1 for composite hot pressing.

[0044] The placement plate 15 is located inside the device box 1 and is used to support the magnesium oxide board 6 and the decorative panel 10. The device box 1 is also provided with a third drive assembly 16 for driving the placement plate 15 to move.

[0045] Please refer to this carefully. Figure 2 , Figure 3 and Figure 4As shown, the third drive assembly 16 includes a first motor 161 installed inside the device housing 1, and the output end of the first motor 161 is connected to a first gear 162 via a rotating rod. The third drive assembly 16 also includes a first lead screw 164 rotatably connected to the inner wall of the device housing 1. Specifically, the two ends of the first lead screw 164 are rotatably connected to the inner wall of the device housing 1 via bearings. A second gear 163 that meshes with the first gear 162 is sleeved at the middle position of the first lead screw 164. Two first sliders 165 are also threadedly connected to the first lead screw 164. The tops of the two first sliders 165 are connected to the bottom of the placement plate 15. When it is necessary to drive the placement plate 15 to rotate, the first motor 161 can drive the first gear 162 to rotate. Since the first gear 162 meshes with the second gear 163, the second gear 163 drives the first lead screw 164 to rotate along with the rotation of the first gear 162. The rotation of the first lead screw 164 enables the first slider 165, which is threaded onto it, to move laterally, thereby allowing the placement plate 15 to move laterally. When the rotation of the first lead screw 164 drives the placement plate 15 to move to the left to its maximum extent, as... Figure 2 As shown, at this time, the placement plate 15 can receive the magnesium oxide board 6 on the left. By driving the first drive assembly 13 on the first storage box 2, the first actuating block 11 drives the magnesium oxide board 6 to move towards the placement plate 15, thereby allowing the uppermost magnesium oxide board 6 to move onto the placement plate 15; and when the rotation of the first lead screw 164 drives the placement plate 15 to move to the right to its maximum extent, as... Figure 4 As shown, at this time, the placement plate 15 can receive the decorative panel 10 on the right. By driving the second drive component 14 on the second storage box 3, the second toggle block 12 drives the decorative panel 10 to move towards the placement plate 15, thereby allowing the uppermost decorative panel 10 to move onto the placement plate 15. The combination of the two allows the magnesium oxide board 6 and the decorative panel 10 to be stacked vertically, while the thermosetting resin film 7 at the upper end of the magnesium oxide board 6 and the thermosetting resin film 7 at the lower end of the decorative panel 10 can be stacked on top of each other, ensuring the adhesion between the magnesium oxide board 6 and the decorative panel 10, and the adhesive effect is better.

[0046] Please refer to this carefully. Figure 2 and Figure 5As shown, a cylinder 17 is installed at the center of the top of the device box 1, and the output end of the cylinder 17 is connected to an upper pressure plate 18. Heating wires 19 are installed inside both the placement plate 15 and the upper pressure plate 18, and the heating wires 19 are distributed in a serpentine structure. When it is necessary to hot press the magnesium oxide board 6 and the decorative panel 10, the second drive assembly 14 causes the placement plate 15 to move laterally to the center of the device box 1, so that the magnesium oxide board 6 and the decorative panel 10 are aligned with the upper pressure plate 18. At this time, the upper pressure plate 18 is lowered to contact the top of the decorative panel 10 by the drive cylinder 17. The heating wires 19 inside the upper pressure plate 18 and the placement plate 15 can melt the thermosetting resin film 7, thereby enabling the magnesium oxide board 6 and the decorative panel 10 to bond together, resulting in a better composite effect.

[0047] Please refer to this carefully. Figure 1 As shown, both the first drive assembly 13 and the second drive assembly 14 include a connecting plate 20 disposed on the side of the device housing 1. The bottom of the connecting plate 20 is connected to a second lead screw 21 extending into the device housing 1. A second slider 22 is threaded onto the second lead screw 21. The bottom of the second slider 22 is connected to either the first actuating block 11 or the second actuating block 12. A second motor 23 is also mounted on the bottom of the connecting plate 20, and the output end of the second motor 23 is connected to one end of the second lead screw 21. Figure 1 (The second motor 23 in the second drive assembly 14 is not shown). By starting the second motor 23, the second lead screw 21 can be rotated. Since the second lead screw 21 is threadedly connected to the second slider 22, the rotation of the second lead screw 21 can cause the second slider 22 to slide along the length of the second lead screw 21, thereby causing the second slider 22 to drive the first actuating block 11 or the second actuating block 12 to move, so that the first actuating block 11 can push the magnesium oxide board 6 into the device box 1, or the second actuating block 12 can push the decorative panel 10 into the device box 1.

[0048] Please refer to this carefully. Figure 1As shown, the number of second lead screws 21 in both the first drive assembly 13 and the second drive assembly 14 is two, and the two second lead screws 21 are connected by a transmission assembly 24. By setting two second lead screws 21, the number of first actuating blocks 11 and second actuating blocks 12 can both be two. The two first actuating blocks 11 are symmetrically arranged, and the two second actuating blocks 12 are also symmetrically arranged. They are linked by the transmission component 24, so that the first actuating block 11 can push the front and rear ends of the side of the magnesium oxide board 6, and the second actuating block 12 can push the front and rear ends of the side of the decorative panel 10, making the magnesium oxide board 6 and the decorative panel 10 more stable when being pushed. Furthermore, in order to facilitate better contact between the magnesium oxide board 6 and the decorative panel 10 and the placement plate 15, the front and rear end faces of the placement plate 15 can be closely attached to the front and rear end faces of the inner wall of the device box 1, and the front and rear widths of the magnesium oxide board 6 and the decorative panel 10 are the same as or only slightly smaller than the front and rear widths of the placement plate 15, so that the front and rear positions of the magnesium oxide board 6 and the decorative panel 10 will not deviate when being pushed left and right, so as to facilitate subsequent hot pressing and the hot pressing effect will be better.

[0049] Please refer to this carefully. Figure 1 As shown, the transmission assembly 24 includes transmission wheels sleeved on two second lead screws 21, and the two transmission wheels are connected by a transmission belt. The transmission assembly 24 is conventional prior art, and is only shown in the figure to enable the two second lead screws 21 to be synchronously driven by a second motor 23. Its specific structure is prior art and will not be described in detail here.

[0050] Please refer to this carefully. Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the placement plate 15 has an internal cavity 25, and two rotating shafts 26 extending to the bottom of the placement plate 15 are connected to the inner bottom of the cavity 25. Cams 28 are fitted onto the outside of each of the two rotating shafts 26. Relief holes 31 communicating with the inside of the cavity 25 are opened on both sides of the top of the placement plate 15. Clamping plates 30, passing through the relief holes 31, are hinged to both sides of the inside of the cavity 25 via pins. Third springs 29 are installed on both sides of the inner wall of the cavity 25, and the other end of each third spring 29 is connected to the clamping plate 30. Third gears 27 are installed at the bottom of each of the two rotating shafts 26. A rack 32 meshing with the third gears 27 is installed on the inner wall of the device box 1. When the placement plate 15 is... Figure 2 Move the center position to the right Figure 3When the gear reaches this position, the third gear 27 will slowly mesh with the rack 32 until it reaches this position, at which point the placement plate 15 is directly below the upper pressure plate 18. At this point, the third gear 27 is exactly in the middle of the rack 32. Since the number of teeth on the rack 32 is half the number of teeth on the third gear 27, when the third gear 27 moves to the middle position of the rack 32, the gear can rotate a quarter turn, thereby causing the rotating shaft 26 to drive the cam 28 to rotate ninety degrees. Figure 7 It can be seen that in the initial position, the narrow edge of the cam 28 corresponds to the clamping plate 30, but does not contact it. Under the action of the third spring 29, the clamping plate 30 is in a position where... Figure 2 In the middle state, when the placement plate 15 moves to the middle position of the device box 1, the cam 28 rotates ninety degrees, which can make the clamping plate 30 be in the middle position. Figure 3 In the vertical state, the clamping plate 30 clamps the two sides of the magnesium oxide board 6. When the placement plate 15 moves to the rightmost end, the third gear 27 disengages from the rack 32. Under the action of the third spring 29, the clamping plate 30 returns to the expanded state. At this time, it is convenient for the decorative panel 10 to slide onto the placement plate 15. Then, the placement plate 15 moves to the middle position of the device box 1, and the cam 28 turns the clamping plate 30 into a vertical state again. At this time, the descent of the upper pressure plate 18 can be used to perform composite hot pressing on the two magnesium oxide boards 6 and the decorative panel 10 clamped by the clamping plate 30. The clamping plate 30 makes the magnesium oxide board 6 aligned with the side of the decorative panel 10, resulting in a better hot pressing effect.

[0051] Please refer to this carefully. Figure 8 As shown, both the first storage box 2 and the second storage box 3 are equipped with a top plate 33, and the bottom of the top plate 33 is equipped with rollers 34. The rollers 34 rotate in the following directions: Figure 8 As shown, and as Figure 2 As shown, each first actuating block 11 and each second actuating block 12 has two actuating points, which are parallel to each other. The first actuating point is used to push the magnesium oxide board 6 or decorative panel 10. After the first actuating point pushes the magnesium oxide board 6 or decorative panel 10, the bottom end of the next actuating point contacts the top end of the next magnesium oxide board 6 or decorative panel 10. When the first actuating point completely pushes the magnesium oxide board 6 or decorative panel 10 onto the mounting plate 15, the bottom end of the first actuating point does not actually contact the top end of the next magnesium oxide board 6 or decorative panel 10. At this time, in order for the first actuating block 11 or the second actuating block 12 to return to its initial position, the second actuating point is set for this purpose. In addition, as Figure 2When the first actuating block 11 or the second actuating block 12 does not push the magnesium oxide board 6 or the decorative panel 10, they do not contact the magnesium oxide board 6 or the decorative panel 10. At this time, the roller 34 is designed to abut against the uppermost magnesium oxide board 6 or the decorative panel 10. The design of the roller 34 also facilitates the sliding of the magnesium oxide board 6 or the decorative panel 10. The roller 34 and the first actuating block 11 or the second actuating block 12 are staggered and there is no movement conflict between them.

[0052] A composite process for a magnesium oxide board composite layer includes the following steps:

[0053] Step 1: Dry the magnesium oxide board 6 substrate to remove moisture, then sand one or both sides of the dried magnesium oxide board 6 substrate to smooth it and remove the dust.

[0054] Step 2: Apply thermosetting resin film 7 to the upper surface of the magnesium oxide board 6 that has been sanded smooth in Step 1; then apply thermosetting resin film 7 to the lower surface of the decorative panel 10. The thermosetting resin film 7 is made of non-woven fabric as the base film and is formed by at least one resin film impregnation and drying process.

[0055] Step 3: Place the covered magnesium oxide board 6 from Step 2 into the inside of the first storage box 2, and place the covered decorative panel 10 into the inside of the second storage box 3.

[0056] Step 4: The magnesium oxide board 6 inside the first storage box 2 and the decorative panel 10 inside the second storage box 3 are fed into the device box 1 one by one, and then the two are hot-pressed together. The hot-pressing conditions are 150°C, 1450psi, and 100min.

[0057] Step 5: Packaging yields the finished composite board.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
