Description

Technical Field

[0001] This invention relates to the field of energy-saving building materials production technology, and in particular to an energy-saving gypsum board production device based on thermal insulation fiber cloth. Background Technology

[0002] Gypsum board is a common building interior wall and partition material. To further improve the thermal insulation performance of gypsum board, insulating fiber cloth (such as glass fiber cloth, polymer fiber cloth, etc.) is usually composited with gypsum substrate as a reinforcing layer during the gypsum board production process. The existing fiber cloth composite gypsum board production process generally involves laying the fiber cloth directly on continuously conveyed gypsum slurry (or board), and then pressing it with devices such as pressing rollers. Existing gypsum board production equipment also adopts energy-saving structures such as waste heat recovery, frequency conversion drive, and hot air management. However, the existing pressing process still has the following obvious defects: Due to the dense structure of the fiber cloth itself and the limited fluidity of the gypsum slurry, gypsum cannot fully and evenly penetrate into the internal gaps and interlacing points of the fiber cloth during the pressing process. This results in only a surface bond between the fiber cloth and the gypsum substrate, with material differences at the bonding interface and weak interface bonding strength. In subsequent use, the two materials are prone to delamination and peeling, which seriously affects the quality of the gypsum board. Summary of the Invention

[0003] In order to overcome the shortcomings mentioned in the background art, the present invention provides an energy-saving gypsum board production device based on thermal insulation fiber cloth.

[0004] The technical solution is as follows: An energy-saving gypsum board production device based on thermal insulation fiber cloth, comprising a conveying base, two symmetrically distributed support frames mounted on the conveying base, a presser jointly mounted between the two support frames, an electric roller jointly rotatably connected between the two support frames, a fixed frame jointly fixed between the two support frames, a connecting shell fixedly connected to the fixed frame, a rotating cylinder rotatably connected to the connecting shell, a plurality of circumferentially distributed first through holes on the rotating cylinder, a plurality of brushes on the rotating cylinder, an inner shaft fixedly connected to the fixed frame and sealed and rotatably connected to the rotating cylinder, a plurality of spaced second through holes on the inner shaft, all second through holes respectively used to connect to corresponding first through holes, a symmetrically distributed feed pipe connected to the inner shaft, the inner shaft used to connect all second through holes to all feed pipes.

[0005] To further explain, the diameter of all the first through holes increases sequentially from the middle to both ends of the rotating cylinder, and the diameter of all the second through holes increases sequentially from the middle to both ends of the inner shaft.

[0006] To further explain, the fixed frame is rotatably connected to a pressure roller, and the electric roller, the rotating cylinder, and the pressure roller are driven by a belt drive structure.

[0007] To further explain, the cross-sectional area of ​​the pressure roller gradually decreases from its middle part to both ends.

[0008] To further explain, the middle part of the pressure roller is made of elastic material, the support frame is provided with an electromagnetic slide rail, an electromagnetic slider is slidably connected inside the electromagnetic slide rail, the electromagnetic slider is fixedly connected to a sliding frame, and the sliding frame is rotatably connected to the pressure roller.

[0009] To further explain, the feed pipe is equipped with a regulating valve, and the regulating valve is connected to the adjacent sliding frame via a transmission component.

[0010] To further explain, the fixing frame is fixedly connected to a support plate located below the connecting shell.

[0011] To further explain, a motor is installed inside the support plate, and the output shaft of the motor is fixedly connected to a rotating shaft that is rotatably connected to the support plate. The rotating shaft is fixedly connected to a flexible sleeve.

[0012] To further explain, the flexible sleeve is fixed with circumferentially evenly distributed convex strips.

[0013] To further explain, the upper side of the support plate is convex, and the fixing frame is fixed to a collection shell located below the support plate.

[0014] The beneficial effects of this invention are as follows: By pre-spraying a portion of gypsum onto the surface of the fiber cloth and then brushing the gypsum into the interior of the fiber cloth using a brush, the uniformity of gypsum penetration into the fiber cloth is improved. This ensures that the surfaces of the fiber cloth and gypsum adhere more easily during subsequent pressing, increasing the strength of the bonding interface between the gypsum and fiber cloth, thereby guaranteeing the quality of the gypsum board after production. By varying the apertures of all the first and second through holes, the amount of gypsum sprayed on the fiber cloth varies, adapting to the uneven accumulation and distribution of gypsum on the conveyor base, improving the flatness of the fiber cloth pressing, and thus improving the quality of the gypsum board after production. This is achieved by adjusting the conveyor... The condition of the plaster surface on the base is adjusted accordingly to change the shape of the pressure roller. The pressure roller is used to level the plaster on the surface of the fiber cloth after it has been brushed by the brush, and to control the distribution of the pre-sprayed plaster on the fiber cloth. This facilitates the pressing of the fiber cloth with the plaster on the conveyor base, improving the quality of the pressed fiber cloth. The rotating flexible sleeve supports the fiber cloth located at the brush, and all the convex strips intermittently squeeze the fiber cloth, ensuring the brush's pre-coating force on the plaster on the fiber cloth and improving the penetration efficiency of the plaster on the fiber cloth. Furthermore, the rotation of the flexible sleeve and all the convex strips reduces the friction on the fiber cloth during the support process, ensuring the quality of the fiber cloth after production.

Detailed Implementation

[0017] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0018] Example 1 The existing pressing process still has the following obvious defects: due to the dense structure of the fiber cloth itself and the limited fluidity of the gypsum slurry, the gypsum cannot fully and evenly penetrate into the internal gaps and interlacing points of the fiber cloth during the pressing process. This results in only a surface bond between the fiber cloth and the gypsum substrate. There is a material difference at the bonding interface, and the interface bonding strength is weak. In subsequent use, the two materials are prone to delamination and peeling, which seriously affects the quality of the gypsum board.

[0019] An energy-saving gypsum board production device based on thermal insulation fiber cloth, such as Figures 1-6As shown, the device includes a conveying base 1, which is equipped with a control terminal (not shown in the figure). Two symmetrically distributed support frames 2 are mounted on the conveying base 1. The conveying base 1 is used for continuous conveying of gypsum. A presser 3 is installed between the two support frames 2. The presser 3 is electrically connected to the control terminal and is used to press the insulating fiber cloth onto the surface of the gypsum. An electric roller 4, which is electrically connected to the control terminal, is rotatably connected between the two support frames 2. The electric roller 4 is used to convey the fiber cloth. When this device is used to produce gypsum board, the fiber cloth is wrapped around the electric roller 4 and the presser 3 and bonded to the gypsum. The two support frames 2 are then fixed together. A fixed frame 5 is connected to a connecting shell 6, which is rotatably connected to a rotating cylinder 7. The rotating cylinder 7 has several circumferentially distributed first through holes 701 and several brushes 8. Rotation of the rotating cylinder 7 drives all the brushes 8 to rotate. When the height of the brushes 8 below the rotating cylinder 7 is lower than the lower side of the connecting shell 6, the brushes 8 below the rotating cylinder 7 are in contact with the surface of the fiber cloth during gypsum board production. The fixed frame 5 is fixed to an inner shaft 9, which is rotatably and sealingly connected to the rotating cylinder 7. The inner shaft 9 has several spaced-apart second through holes 901, all of which are used to connect to the... The inner shaft 9 is connected to symmetrically distributed feed pipes 10 through the first through hole 701. The feed pipes 10 are connected to an external injection device (not shown in the figure) for injecting plaster into the feed pipes 10. The plaster is then fed into the inner shaft 9 through the feed pipes 10. The plaster passes through all the second through holes 901 and enters all the first through holes 701, causing the plaster to be sprayed onto the brush 8 and the surface of the fiber cloth. The brush 8 is used to brush the plaster into the interior of the fiber cloth, allowing it to penetrate the fiber cloth evenly. This improves the uniformity of plaster penetration and ensures that the bonding interface material between the fiber cloth and plaster is the same during subsequent pressing, thus increasing the strength of the bonding interface between the plaster and the fiber cloth. To ensure the quality of gypsum board production, the inner shaft 9 connects all the second through holes 901 to all the feed pipes 10. The diameter of all the first through holes 701 increases sequentially from the middle to both ends of the rotating cylinder 7, and the diameter of all the second through holes 901 increases sequentially from the middle to both ends of the inner shaft 9. Through the changes in the diameter of all the first through holes 701 and all the second through holes 901, less gypsum is sprayed in the middle of the fiber cloth, while more gypsum is sprayed on the front two sides of the fiber cloth. This is to accommodate the situation where the gypsum on the conveying base 1 accumulates in the middle due to its poor fluidity, thereby improving the flatness of the fiber cloth pressing and thus improving the quality of the gypsum board after production.

[0020] like Figure 2 and Figure 6As shown, the fixed frame 5 is rotatably connected to the pressure roller 11. The cross-sectional area of ​​the pressure roller 11 gradually decreases from the middle to both ends. The pressure roller 11 is used to level the plaster on the surface of the fiber cloth after it has been brushed by the brush 8, so that the fiber cloth can be pressed together with the plaster on the conveying base 1. The electric roller 4, the rotating cylinder 7 and the pressure roller 11 are driven by a belt drive structure. The corresponding pulley of the belt drive structure on the pressure roller 11 is rotatably connected to the fixed frame 5. When the electric roller 4 rotates, the electric roller 4 drives the rotating cylinder 7 and the pressure roller 11 to rotate through the belt drive structure.

[0021] The specific workflow is as follows: When the operator needs to use this device to produce gypsum board, the operator continuously conveys the gypsum through the conveying base 1, and passes the fiber cloth around the electric roller 4 and the presser 3 and puts it into contact with the gypsum on the conveying base 1 (the gypsum on the conveying base 1 moves from right to left, and when the fiber cloth passes around the electric roller 4 and the presser 3, it also moves to the left along the surface of the gypsum on the conveying base 1). Then, the operator turns on the electric roller 4 and the presser 3 through the control terminal. The electric roller 4 drives the fiber cloth to move, and the presser 3 presses the fiber cloth onto the surface of the gypsum.

[0022] During the pressing process of the fiber cloth, the operator injects gypsum into the feed pipe 10 through an external injection device. The feed pipe 10 feeds the gypsum into the inner shaft 9. The gypsum passes through all the second through holes 901 and enters all the first through holes 701, so that the gypsum is sprayed onto the brush 8 and the surface of the fiber cloth. At the same time, when the electric roller 4 rotates, the electric roller 4 drives the rotating cylinder 7 and the pressure roller 11 to rotate through the belt drive structure. The rotating cylinder 7 drives all the brushes 8 on it to rotate. The brushes 8 are used to brush the gypsum into the interior of the fiber cloth. The gypsum penetrates into all parts of the fiber cloth, improving the uniformity of the gypsum penetration into the fiber cloth. It also ensures that when the fiber cloth and gypsum are pressed together, the bonding interface material of the two surfaces is the same, improving the strength of the bonding interface between the gypsum and the fiber cloth, thereby ensuring the quality of the gypsum board after production.

[0023] During the process of the electric roller 4 driving the pressure roller 11 to rotate through the belt drive structure, the pressure roller 11 flattens the gypsum on the surface of the fiber cloth after it has been brushed by the brush 8, so that the fiber cloth can be pressed together with the gypsum on the conveying base 1. After the above pretreatment, the fiber cloth is pressed onto the gypsum surface by the presser 3, thereby realizing the production of gypsum board.

[0024] When the operator needs to stop using this device to produce gypsum board, the conveyor base 1 will no longer convey gypsum. The operator will then turn off the electric roller 4 and the press 3 via the control terminal and clean the device for the next use.

[0025] Example 2 Based on Example 1, such as Figure 2 and Figure 6As shown, the middle part of the pressure roller 11 is made of an elastic material, such as rubber. In this embodiment, the pressure roller 11 is connected to the corresponding pulley spline on the belt drive structure. The conveying base 1 is equipped with a laser monitoring structure for monitoring the flatness of the plaster surface. This laser detection structure is an existing device and is not shown in the figure. The support frame 2 is equipped with an electromagnetic slide rail electrically connected to the control terminal. An electromagnetic slider 13 is slidably connected inside the electromagnetic slide rail. A sliding frame 12 is fixedly connected to the electromagnetic slider 13. The sliding frame 12 is rotatably connected to the pressure roller 11. The electromagnetic slider 13 is used to drive the sliding frame 12 to move, so as to squeeze and pull the pressure roller 11 through the two sliding frames 12. When the pressure roller 11 slides relative to the corresponding pulley on the belt drive structure, after the laser monitoring structure detects the surface condition of the gypsum on the conveying base 1, if the height difference between the middle and the front and rear sides of the gypsum on the conveying base 1 is small, the two sliding frames 12 are moved in opposite directions, the pressure roller 11 is stretched, and the height difference between the middle and the front and rear sides of the pressure roller 11 decreases synchronously. If the height difference between the middle and the front and rear sides of the gypsum on the conveying base 1 is large, the two sliding frames 12 are moved in opposite directions, the pressure roller 11 is deformed under pressure, and the height difference between the middle and the front and rear sides of the pressure roller 11 increases synchronously. According to the surface condition of the gypsum on the conveying base 1, the distribution state of the pre-sprayed gypsum on the fiber cloth is adjusted accordingly.

[0026] like Figure 6 As shown, the feed pipe 10 is equipped with a regulating valve 14. The regulating valve 14 is connected to the adjacent sliding frame 12 by a transmission component. The transmission component consists of a rack fixed to the sliding frame 12 and a gear fixed to the valve stem of the regulating valve 14. If the drop between the middle and the front and rear sides of the gypsum on the conveying base 1 is small, the two sliding frames 12 move in opposite directions. The sliding frame 12 drives the valve stem of the adjacent regulating valve 14 to rotate through the transmission component, thereby reducing the flow rate of the regulating valve 14 and reducing the amount of gypsum entering the feed pipe 10. If the drop between the middle and the front and rear sides of the gypsum on the conveying base 1 is large, the two sliding frames 12 move in opposite directions. The sliding frame 12 drives the valve stem of the regulating valve 14 to rotate through the transmission component, thereby increasing the flow rate of the regulating valve 14 and increasing the amount of gypsum entering the feed pipe 10. When the drop between the middle and the front and rear sides of the gypsum on the conveying base 1 is large, more gypsum is pre-added to the front and rear sides of the fiber cloth to accommodate the amount of gypsum that can be squeezed after the pressure roller 11 is deformed.

[0027] Example 3 Based on Example 2, such as Figures 3-5 and Figure 7As shown, the fixing frame 5 is fixedly connected to a support plate 15 located below the connecting shell 6. The upper side of the support plate 15 is convex. The fixing frame 5 is fixedly connected to a collection shell 20 located below the support plate 15. The plaster dripping from the connecting shell 6 onto its upper surface is guided into the collection shell 20 through the convex surface of the support plate 15, so as to facilitate the recycling of the dripping plaster. A motor 16 electrically connected to the control terminal is installed inside the support plate 15. The output shaft of the motor 16 is fixedly connected to a rotating shaft 17 rotatably connected to the support plate 15. The rotating shaft 17 is located below all the brushes 8. A flexible sleeve 18 is fixedly connected to the rotating shaft 17. The flexible sleeve 18 is fixed with circumferentially evenly distributed convex strips 19. The output shaft of the motor 16 is used to drive the rotating shaft 17 to rotate, so that the flexible sleeve 18 drives all the convex strips 19 on it to rotate. The rotating flexible sleeve 18 supports the lower side of the fiber cloth located at the brush 8. All the convex strips 19 intermittently squeeze the fiber cloth, ensuring the strength of the brush 8 in pre-coating the gypsum on the fiber cloth, improving the penetration efficiency of the gypsum on the fiber cloth, and using the rotation of the flexible sleeve 18 and the rotation of all the convex strips 19 to reduce the friction force on the fiber cloth during the support process, ensuring the quality of the fiber cloth after production.

[0028] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
