Description

Technical Field

[0001] The present invention relates to the technical field of gypsum-based board materials, and in particular to a gypsum-based board processing system and method. Background Art

[0002] Gypsum board is widely used in the construction industry as a covering material for building components such as walls and ceilings. Its production process usually includes multiple steps such as the production of gypsum powder, mixing with water, pouring, and curing. Existing gypsum board substrate processing methods mostly rely on traditional manual operations, which are inefficient. In addition, due to the brittleness of gypsum materials, the production process is prone to waste of raw materials and equipment wear. Traditional gypsum-based boards are used as the base material for partition walls and suspended ceilings, and require secondary decoration. They also require puttying, painting, and wallpapering. The construction period is long, the labor cost is high, the construction environment is poor, and it may also cause secondary pollution.

[0011] A method for processing a gypsum board substrate, which is applied to the gypsum-based board processing system described above, includes the following steps:

[0012] S1. Raw material preparation;

[0013] S2. Edge treatment: Perform UV edge coating on the side of the gypsum board to make the edges and corners of the gypsum-based board smooth and beautiful, and the gypsum powder is cured and does not shed powder;

[0014] S3. Gluing the gypsum board: Uniformly roll-coat the adhesive on the front of the gypsum board and sweep it flat with a leveling roller;

[0015] S4. Heating the gypsum board in a constant-temperature oven;

[0016] S5. Gluing the PET film: When covering three sides, uniformly apply the adhesive on both sides of the back of the PET film; when flatly pasting on both sides, the PET film is not glued;

[0017] S6. Drying and reaction: Perform preliminary drying on the glued gypsum board and PET film or let the adhesive react with moisture to remove excess solvent or moisture or preliminarily cure the adhesive;

[0018] S7. Flat pasting and covering pasting treatment;

[0019] S8. Edge trimming: Remove the excess PET film at the edges.

[0020] Preferably, the edge treatment in step S2 includes the following steps:

[0021] S21. Edge coating with UV paint: When using the three-sided coating method for film laminating, apply white or UV paint of the same color as the surface decorative film material to the four corners of the gypsum board for edge coating treatment to ensure smooth and beautiful corners, solidify the gypsum powder, and prevent powder shedding; when using the double-sided flat laminating method for film laminating, apply UV paint of the same color as the surface decorative film material to the four corners of the gypsum board for edge coating treatment to ensure smooth and consistent color corners, solidify the gypsum powder, and prevent powder shedding;

[0022] S22. Curing: Use a UV lamp for rapid curing.

[0023] Preferably, step S7 includes the following steps:

[0024] S71. Positioning: When using the three-sided coating method, accurately place the PET film with adhesive evenly applied on both sides of the back on the gypsum board; when using the double-sided flat laminating method, directly place the PET film accurately on the gypsum board to ensure no bubbles and wrinkles;

[0025] S72. Pressurizing: Apply a certain pressure to the PET film using a roller or a press to make it closely adhere to the gypsum board;

[0026] S73. Heat curing or reactive curing: Through hot pressing, infrared heating, or the reaction of the reactive adhesive with water, make the adhesive completely cured, improve the adhesion between the PET film and the gypsum board, and ensure that the PET film is flat and wrinkle-free on both the front and back sides and the two side surfaces of the gypsum board.

[0027] Preferably, when the thickness of the PET film is 0.14 mm - 0.25 mm, use the three-sided coating method for film laminating. The three-sided coating method is that for the flat lamination of the front part, glue is applied to the surface of the gypsum board and the film material is not coated with glue. When it comes to pressure lamination, the film material is flat laminated. Before flat lamination, apply glue to both sides of the back of the film material. After flat lamination, enter the coating wheel to achieve the lamination of the side and back of the gypsum board. Before three-sided coating, apply UV paint to the four sides of the gypsum board to solidify the gypsum powder on the four sides of the gypsum board, prevent powder shedding, and make the surface decorative film material firmly adhere to the gypsum board.

[0028] When the thickness of the PET film or other material films is 0.25 mm - 0.3 mm and above, use the double-sided flat laminating method for film laminating. The double-sided flat laminating method is to apply glue on the gypsum board. Before double-sided flat lamination, apply UV paint of the same color to the four sides of the gypsum board to achieve a uniform color throughout the gypsum-based board.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The PET film is a material with good decorative properties, touch, tensile strength and moisture resistance. Combined with the gypsum substrate (gypsum board) as the surface layer, it helps to enhance the decorative, moisture-proof, waterproof and anti-fouling capabilities of the gypsum substrate, transforming the gypsum-based board from a basic board into a decorative board. Gypsum powder is the main component of the gypsum substrate, providing the hardness and stability of the gypsum substrate. The performance of the gypsum substrate is adjusted through additives, such as enhancing strength, improving moisture resistance, and enhancing workability, etc., to optimize the overall performance of the gypsum substrate. The gypsum powder and additives are mixed and dried to make the gypsum substrate. After cutting the PET film to a size suitable for the gypsum substrate according to the specified thickness, it is set on the outer surface of the gypsum substrate. There are upper facing paper and lower facing paper on the outside of the gypsum substrate, which are used to provide strength, support and protection for the gypsum substrate, enhance the durability of the substrate, and prevent the gypsum substrate from cracking or wearing. The ratio of the upper facing paper, lower facing paper, gypsum powder, and additives has been adjusted through experiments, and the impact resistance, hardness, and fracture load are significantly stronger than those of the existing ordinary gypsum-based boards.

[0040] The present invention provides the following embodiments

[0041] Embodiment 1

[0042] An embodiment of the present invention provides a gypsum-based board processing system, as Figures 1-3 shown, including: a support frame 3, a conveyor assembly 4 is provided on the support frame 3, a gypsum mixing assembly 6 is provided above the conveyor assembly 4, a pressing structure 31 is provided at the end of the forward direction of the conveyor assembly 4, and a gypsum cleaning assembly 8 is provided on one side of the forward direction of the conveyor assembly 4.

[0043] The working principle and beneficial effects of the above technical solution are as follows: when it is necessary to produce gypsum-based panels, the conveying assembly 4 is started, and the lower face paper is conveyed through the conveying assembly 4. When the lower face paper is conveyed to the gypsum stirring assembly 6, gypsum powder, water and additives are input into the gypsum stirring assembly 6. The gypsum stirring assembly 6 is started to output the gypsum mixture onto the lower face paper. Subsequently, the conveying assembly 4 conveys the lower face paper and the gypsum mixture to the pressing structure. The pressing structure presses the upper face paper, the lower face paper and the gypsum mixture into a board. When the gypsum stirring assembly 6 stops conveying the gypsum mixture, the gypsum cleaning assembly 8 cleans the output end of the gypsum stirring assembly 6.

[0044] The present invention utilizes the conveying component 4 to convey the lower face paper. This design can ensure that the lower face paper remains stable during the conveying process and ensure the flatness of the gypsum-based board pressed by the pressing structure. The all-round mixing effect of the gypsum stirring component 6 can ensure the uniformity of the gypsum mixture, thereby improving the quality of the gypsum-based board. The design of the gypsum cleaning component 8 avoids the solidification of the gypsum at the output end of the gypsum stirring component 6 after shutdown, resulting in a reduction in the output flow of the gypsum stirring component 6.

[0045] Example 2

[0046] On the basis of Example 1, Figures 1-3 As shown, the conveying assembly 4 includes two driving rollers 41, and the two driving rollers 41 are symmetrically rotated and connected to the support frame 3. A number of receiving rollers 42 are provided between the driving rollers 41, and the number of receiving rollers 42 are rotatably connected to the support frame 3. The two driving rollers 41 are connected by a belt 43, and the belt 43 and the number of receiving rollers 42 roll relative to each other. One end of the driving roller 41 is connected to the driving motor 44 through a deceleration structure, and the driving motor 44 is bolted to the bottom of the support frame 3. The belt at the bottom of the support frame 3 is provided with a tensioning structure 5.

[0047] The tensioning structure 5 includes a tensioning frame 51, which is bolted to the supporting frame 3. Support rods 52 are symmetrically fixedly connected to the tensioning frame 51, and tensioning sleeves 53 are slidably connected to the support rods 52. An elastic compression member 54 is provided between the support rods 52 and the tensioning sleeves 53. A tensioning roller 55 is rotatably connected to the tensioning sleeve 53, and the tensioning roller 55 slides relative to the belt 43.

[0048] The working principle and beneficial effects of the above technical solution are as follows: the two drive rollers 41 are connected to the support frame 3 in a symmetrical rotation manner, and are connected by a belt 43. One end of the drive roller 41 is connected to the drive motor 44 through a reduction structure. When the drive motor 44 is started, it transmits power to the drive roller 41 through the reduction structure, causing the drive roller 41 to start rotating. Since the two drive rollers 41 are connected by a belt 43, when the drive roller 41 rotates, the belt 43 will also rotate. At the same time, the belt 43 rolls relative to a number of receiving rollers 42, which support and guide the belt 43. The function is to ensure that the belt 43 remains stable and continuous during the conveying process. During the conveying process of the belt 43, the tensioning structure 5 is used to adjust the tension of the belt 43 to ensure that the belt 43 will not be too loose or too tight during the conveying process. The tensioning frame 51 is bolted to the supporting frame 3, and a tensioning sleeve 53 is slidably connected to the support rod 52. An elastic compression member 54 is provided between the support rod 52 and the tensioning sleeve 53 to provide an outward thrust for the tensioning sleeve 53 so that it is always close to the belt 43. A tensioning roller 55 is rotatably connected to the tensioning sleeve 53, and the tensioning roller 55 slides relative to the belt 43 to further ensure the smooth operation of the belt 43.

[0049] The present invention realizes continuous and stable transportation of the gypsum mixture and the lower face paper through the coordinated action of the driving roller 41, the receiving roller 42 and the belt 43, thereby improving production efficiency. The design of the receiving roller 42 can avoid the sagging problem of the belt 43 due to its material characteristics during transportation, and can also utilize the synchronization of the belt 43 transportation. The design of the tensioning structure 5 allows the tension of the belt 43 to be adjusted as needed, ensuring that the belt 43 maintains appropriate tension during transportation, avoiding problems such as unstable transportation or damage to the belt 43 caused by being too loose or too tight. The structure of the entire conveying assembly 4 is relatively simple, with fewer parts, and is easy to install and maintain.

[0050] Example 3

[0051] On the basis of Example 2, Figures 1-3As shown, the gypsum stirring assembly 6 includes a circular stirring hopper 61, which is bolted to the support frame 62. The support frame 62 is arranged on both sides of the support rack 3. A closed top cover 63 is spirally connected to the top of the circular stirring hopper 61. A stirring wheel 64 is arranged between the circular stirring hopper 61 and the closed top cover 63. A rotating shaft 65 is key-connected to the stirring wheel 64. The rotating shaft 65 passes through and is rotatably connected to the closed top cover 63. A stirring motor 66 is bolted to the side of the support frame 62. Pulley 67 is key-connected to both the rotating shaft 65 and the working end of the stirring motor 66. The pulleys 67 are connected by a transmission belt 68. A feeding pipe 69 passes through and is connected to the closed top cover 63. A discharge structure 7 is arranged on the side of the circular stirring hopper 61.

[0052] The discharge structure 7 includes a discharge pipe 71, which is bolted to the circular stirring hopper 61. A discharge port 72 is arranged between the discharge pipe 71 and the circular stirring hopper 61. A discharge drag pipe 73 is bolted to the discharge port 72. A pull rod 74 is nested at the output end of the discharge drag pipe 73. The pull rod 74 is bolted to the pick rod 75. The pick rod 75 is fixedly connected to the support frame 62.

[0053] The working principle and beneficial effects of the above technical solution are as follows: When it is necessary to stir materials such as gypsum, first start the stirring motor 66. The pulley 67 is key-connected to the working end of the stirring motor 66, and this pulley 67 is connected to the pulley 67 on the rotating shaft 65 through the transmission belt 68. Therefore, when the stirring motor 66 rotates, its power is transmitted to the rotating shaft 65 through the transmission belt 68. The rotating shaft 65 passes through and is rotatably connected to the closed top cover 63, and the stirring wheel 64 is key-connected to the rotating shaft 65. Therefore, when the rotating shaft 65 rotates, the stirring wheel 64 will also rotate accordingly. Then, open the feeding pipe 69 to convey gypsum powder and its additives into the circular stirring hopper 61. When the stirring wheel 64 rotates in the circular stirring hopper 61, it will drive the gypsum powder and its additives to be mixed. Due to the rotation of the stirring wheel 64 and the shape design of the circular stirring hopper 61, the materials will have a complex movement trajectory in the circular stirring hopper 61, so as to achieve all-round mixing. When the stirring is completed, the gypsum mixture is thrown out from the discharge port 72 under the action of centrifugal force, and then enters the discharge drag pipe 73 through the discharge pipe 71. After the speed of the gypsum mixture is reduced in the discharge drag pipe 73, it is discharged outwards. The pull rod 74 and the pick rod 75 make the discharge drag pipe 73 suspended, avoiding contact with the lower facing paper;

[0054] The present invention drives the stirring wheel 64 to rotate through the stirring motor 66, which can achieve the rapid and uniform mixing of materials such as gypsum, improve the stirring efficiency, and the sealing design between the closed top cover 63 and the circular stirring hopper 61 can prevent the leakage of materials during the stirring process, maintaining the cleanliness and safety of the working environment. Moreover, the design of the discharge structure 7 enables the gypsum mixture to be thrown out by centrifugal force without the need for pumping, ensuring the output efficiency of the gypsum mixture. In addition, the pull rod 74 and the pick rod 75 can prevent the discharge drag pipe 73 from disturbing the lower facing paper.

[0055] Embodiment 4

[0056] On the basis of Embodiment 3, as Figures 1-3 shown, the gypsum cleaning assembly 8 includes a gantry 81. Both ends of the bottom of the gantry 81 are rotatably connected with rollers 82, and the rollers 82 are slidably connected to the support frame 3. A lead screw 83 penetrates and is threadedly connected to the gantry 81. The top of the lead screw 83 is bolted with a handwheel 84. The bottom of the lead screw 83 is rotatably connected with a collection bin 85. Both sides of the collection bin 85 are slidably connected in a limit groove 86, and the limit groove 86 is arranged on the gantry 81. A high-pressure water spray pipe 87 penetrates and is fixedly connected to the collection bin 85.

[0057] The working principle and beneficial effects of the above technical solution are as follows: After the gypsum stirring assembly 6 stops working, push the gantry 81 to make the rollers 82 roll forward along both sides of the support frame 3 until reaching the discharge drag pipe 73. Then rotate the handwheel 84 to make the lead screw rotate and descend relative to the gantry 81. During the rotation of the lead screw, the collection bin 85 descends along the limit groove 86. When the high-pressure water spray pipe on the collection bin 85 aligns with the discharge drag pipe 73, push the gantry 81 to insert the high-pressure water spray pipe into the discharge drag pipe 73, and the high-pressure water flow flushes the solidified gypsum into the collection bin 85;

[0058] The present invention can quickly and effectively remove the solidified gypsum in the discharge drag pipe 73 by means of high-pressure water flow flushing, improving the cleaning efficiency. The design of the gantry 81 and the collection bin 85 enables the gypsum cleaning assembly 8 to flexibly move to the position where cleaning is required and can adjust the height and angle according to the actual situation to ensure the cleaning effect. The flushed gypsum is directly collected into the collection bin 85, avoiding the problems of gypsum scattering and environmental pollution, and at the same time facilitating subsequent treatment and disposal. The entire cleaning process mainly relies on two simple operations of pushing the gantry 81 and rotating the handwheel 84, without the need for complex equipment and professional skills, reducing the operation difficulty and cost. Moreover, by cleaning the discharge drag pipe 73, it can prevent the blockage of the discharge drag pipe 73 by the solidified gypsum mixture and ensure the output flow rate of the discharge drag pipe 73.

[0059] Embodiment 5

[0060] Based on Embodiment 4, as Figure 4 shown, a processing method for gypsum-based boards, which is applied to a gypsum-based board processing system described in any one of the above, includes the following steps:

[0061] S1. Preparation of raw materials;

[0062] S2. Edge treatment: Perform UV edge coating on the side of the gypsum board to make the edges and corners of the gypsum-based board smooth and beautiful, and the gypsum powder is cured and does not shed powder;

[0063] S3. Glue coating on the gypsum board: Uniformly roll coat the adhesive on the front of the gypsum board and sweep it flat with a leveling roller;

[0064] S4. Heat the gypsum board in a constant-temperature oven;

[0065] S5. Glue coating on the PET film: When three-sided covering, uniformly apply the adhesive on both sides of the back of the PET film; when double-sided flat sticking, the PET film is not coated with glue;

[0066] S6. Drying and reaction: Perform preliminary drying on the glue-coated gypsum board and PET film, or react the adhesive with moisture to remove excess solvent or moisture or preliminarily cure the adhesive;

[0067] S7. Flat sticking and covering sticking treatment;

[0068] S8. Edge trimming treatment: Remove the excess PET film at the edges.

[0069] The working principle and beneficial effects of the above technical solution are as follows: Select appropriate all constituent materials such as gypsum powder, PET film, additives, etc., and perform pre-treatment to ensure that the material quality meets the production requirements. First, perform UV edge coating on the side of the gypsum board (gypsum base board) to make the edges and corners of the gypsum board smooth and beautiful, and the gypsum powder is cured and does not shed powder. When three-sided covering, apply the adhesive on the front surface of the gypsum board and both sides of the back of decorative films such as PET film, so that decorative films such as PET film can effectively bond with the front, both sides and the back of the gypsum board to form a strong composite structure. By drying to remove the moisture or solvent on the surface of decorative films such as PET film or through the chemical reaction of the adhesive with moisture, ensure the bonding effect between the glue-coated gypsum board and the film, bond the PET film to the surface, both sides and the back of the gypsum base board, ensure its firm bonding, and remove air bubbles and wrinkles. Finally, process the excess PET film at the edge part of the gypsum base board to ensure the aesthetics and stability of the product.

[0070] Embodiment 6

[0071] Based on Embodiment 5, the edge treatment in step S2 includes the following steps:

[0072] S21. Edge coating with UV coating: When using the three-sided coating method for film lamination, at the four corners of the gypsum board, use white or UV coating of the same color as the surface decorative film material for edge coating treatment to ensure smooth and beautiful corners, solidify the gypsum powder, and prevent powder shedding. When using the double-sided flat lamination method for film lamination, at the four corners of the gypsum board, use UV coating of the same color as the surface decorative film material for edge coating treatment to ensure smooth and consistent color at the corners, solidify the gypsum powder, and prevent powder shedding.

[0073] S22. Curing: Use a UV lamp for rapid curing.

[0074] The working principle and beneficial effects of the above technical solution are as follows: For edge coating with UV coating at the four corners of the gypsum substrate, when using the three-sided coating method, use white or UV coating of the same color as the surface decorative film material for edge coating to ensure smooth edges of the gypsum substrate, solidify the gypsum powder, and prevent powder shedding. When using the double-sided flat lamination method, use UV coating of the same color as the surface decorative film material for edge coating to ensure consistent overall color and smooth edges. Use a UV lamp for rapid curing to ensure good curing effect of the coating and the durability of the edges. This step ensures the aesthetics and practicality of the gypsum-based board, makes the edge treatment of the product smooth, and has better visual and tactile effects.

[0075] Example 7

[0076] Based on Example 6, step S7 includes the following steps:

[0077] S71. Positioning: When using the three-sided coating method, precisely place the PET film with evenly applied adhesive on both sides of the back on the gypsum board. When using the double-sided flat lamination method, directly place the PET film precisely on the gypsum board to ensure no bubbles and wrinkles.

[0078] S72. Pressurization: Use a roller or press to apply a certain pressure to the PET film to make it closely adhere to the gypsum substrate.

[0079] S73. Heat curing or reactive curing: Through hot pressing, infrared heating, or the reaction of the reactive adhesive with water, completely cure the adhesive to improve the adhesion between the PET film and the gypsum board, and ensure that the PET film is flat and wrinkle-free on both the front and back sides and both sides of the gypsum board.

[0080] The working principle and beneficial effects of the above technical solution are as follows: Positioning can ensure the precise position of the PET film on the gypsum substrate, avoid bubbles or wrinkles, and ensure the laminating effect. Pressurization can apply pressure using a press or rollers to ensure close contact between the PET film and the gypsum substrate. Heat curing or reactive curing can cure the adhesive by means of hot pressing, infrared heating, or the reaction of the reactive adhesive with moisture, ensuring firm bonding between the PET film and the gypsum substrate and guaranteeing a flat surface. The key to this step lies in ensuring the close combination of the PET film and the gypsum substrate, the flatness of the gypsum board substrate, the coating method of the adhesive, the laminating method of the gypsum board and the PET film, the viscosity and open time of the adhesive, and avoiding unevenness to ensure the durability of the gypsum-based board.

[0081] Example 8

[0082] Based on Example 7, when the thickness of the PET film is 0.14 mm - 0.25 mm, the three-sided lamination method is used for film lamination. In the three-sided lamination method, for the flat lamination on the front side, glue is applied to the surface of the gypsum board and no glue is applied to the film material. When it comes to pressing, the film material is flat laminated. Before flat lamination, glue is scraped on both sides of the back of the film material. After flat lamination, it enters the covering wheel to achieve the covering of the sides and back of the gypsum board. Before three-sided lamination, UV coating is applied to the four sides of the gypsum board to cure the gypsum powder on the four sides of the gypsum board so that it does not shed powder and make the surface decorative film material firmly bonded to the gypsum board. When the thickness of the PET film or other material films is 0.25 mm - 0.3 mm and above, the double-sided flat lamination method is used for film lamination. In the double-sided flat lamination method, glue is applied to the gypsum board. Before double-sided flat lamination, UV coating of the same color is applied to the four sides of the gypsum board to achieve the same color throughout the gypsum-based board.

[0083] The working principle and beneficial effects of the above technical solution are as follows: For PET films with a thickness of 0.14 mm - 0.25 mm, the three-sided lamination method is adopted. By applying glue on both sides of the film and using the covering wheel to achieve the covering of the sides and back of the gypsum board. For PET films or other material films with a thickness of 0.25 mm - 0.3 mm and above, the double-sided flat lamination method is adopted, directly applying glue on the gypsum board and performing double-sided film lamination. This different film lamination method ensures the optimization of the production process according to the different thicknesses of the film materials and improves the quality of the final product.
