Description

Technical Field

[0001] This application relates to the field of gypsum board production technology, specifically to a gypsum board substrate production device with adjustable thickness. Background Technology

[0002] In the gypsum board production industry, as a widely used building decoration material, the production quality and efficiency of gypsum board are of paramount importance. Currently, the production process of gypsum board typically employs a backing paper conveying method on a conveyor belt. Specifically, the backing paper moves continuously under the drive of the conveyor belt. During the backing paper conveying process, gypsum slurry is added to its surface, followed by the top paper. Then, a pressing device, in conjunction with the operation of the conveyor, presses the three together. This process aims to ensure that the gypsum slurry is evenly spread between the top and backing papers and achieves the expected thickness standard, thereby ensuring that the final gypsum board has good quality and performance.

[0003] In common production lines, the cladding boards mostly adopt a fixed structure and are numerous. When faced with the production needs of gypsum boards of different thicknesses, it is extremely inconvenient to adjust them. When producing gypsum boards of different thicknesses, it is difficult to accurately control the thickness of the gypsum boards because the cladding boards cannot quickly and effectively adjust the spacing between them and the face paper and back paper. This not only affects production efficiency but may also lead to uneven gypsum board thickness, thus affecting the overall quality of the product. In addition, the fixed structure of the cladding boards lacks an effective limiting and guiding mechanism when conveying face paper and back paper of different sizes, which can easily cause the face paper and back paper to shift during the conveying process, further reducing the production quality of the gypsum boards. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an adjustable-thickness gypsum board substrate production apparatus, which has advantages such as easy adjustment and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: an adjustable thickness gypsum board substrate production device, including a conveyor, a feeding pipe and several pressing components, wherein the feeding pipe is disposed above one end of the conveyor, and a T-shaped pipe is rotatably connected to the bottom end of the feeding pipe, and feeding holes are uniformly opened on the outer surface of the T-shaped pipe along its axial direction.

[0006] Several of the pressing components are arranged side by side at equal intervals along the conveying direction of the conveyor, and the several pressing components move synchronously in the vertical direction to adjust their distance from the conveyor;

[0007] Each of the pressing components includes a frame, with a pressure roller rotatably connected between the front and rear inner sidewalls of the bottom of the frame. Two shaft plates are fixedly connected to the upper surface of the frame, and a bidirectional lead screw is rotatably connected between the two shaft plates. Guide plates are threaded to both ends of the bidirectional lead screw, and built-in spring telescopic rods are fixedly connected to both ends of the two guide plates. Each built-in spring telescopic rod is perpendicular to the conveyor belt, and a side plate is fixedly connected to the movable end of each built-in spring telescopic rod. Several limit wheels are rotatably connected to the side of each side plate near the conveyor.

[0008] Furthermore, a support frame is provided at one end of the conveyor, a mixing tank is fixedly installed at the top of the support frame, the bottom of the mixing tank is fixedly connected to the discharge pipe, an agitator is rotatably connected to the top of the mixing tank, the agitator is located inside the mixing tank, the top of the agitator is connected to an external power source, a flow meter is provided in the middle of the discharge pipe, and an electric valve is installed at the bottom of the mixing tank.

[0009] The above scheme controls the degree of closure of the electric valve and, in conjunction with a flow meter, the amount of slurry falling can be controlled, thereby controlling the flow rate of the slurry according to the thickness of the gypsum board.

[0010] Furthermore, a power plate is fixedly connected to the bottom end of the discharge tube, a power shaft is rotatably connected to the bottom of the power plate, gears are fixedly connected to the top of both the power shaft and the T-shaped tube, the two gears are meshed together, a motor is installed on the upper surface of the power plate, and the output end of the motor is fixedly connected to the power shaft.

[0011] The above solution enables the T-tube to rotate, thereby flexibly adjusting the positions of both ends of the T-tube according to the needs of producing gypsum boards of different widths.

[0012] Furthermore, both sides of the conveyor are equipped with base plates, and electric push rods are installed on the upper surface of the two base plates. Each electric push rod has a lifting plate fixedly connected to its output end, and one end of each frame is fixedly connected to the lifting plate adjacent to it.

[0013] The above scheme uses electric actuators to move the lifting plate up and down, which in turn moves the pressing assembly up and down, thereby controlling the distance between the frame and the conveyor, controlling the distance between the pressure roller and the face paper, and ultimately controlling the thickness of the gypsum board.

[0014] Furthermore, a set of guide rods is fixedly connected to the bottom of each of the two lifting plates, and each guide rod is slidably inserted into the bottom plate adjacent to it.

[0015] The above scheme and settings provide guidance for the vertical movement of the lifting plate, ensuring its stability during movement and preventing deviation, thereby ensuring that the pressing components can accurately control the thickness of the gypsum board.

[0016] Furthermore, one end of each of the bidirectional lead screws is connected to an external power source.

[0017] The above solution uses an external power source to drive a bidirectional lead screw to rotate, which can move the two guide plates closer or further apart, thereby adjusting the distance between the two guide plates. This limits the movement of face paper and back paper of different sizes, preventing deviation during conveying and ensuring the production quality of gypsum board.

[0018] Furthermore, a conveyor frame is fixedly connected to the upper surface of each of the two lifting plates near the material drop pipe, and a composite roller is rotatably connected between the two conveyor frames.

[0019] The above scheme achieves the purpose of conveying the face paper by setting up a paper feeder above the composite roller in conjunction with the composite roller, thereby placing the pulp between the face paper and the back paper. The composite roller can also be used to guide the face paper.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] This adjustable-thickness gypsum board substrate production device uses an electric actuator to move a lifting plate up and down, which in turn moves the entire pressing assembly. It can easily control the distance between the frame and the conveyor, thereby precisely adjusting the distance between the pressure roller and the face paper, achieving flexible control of the gypsum board thickness. When facing the production needs of gypsum boards of different thicknesses, there is no need to make cumbersome adjustments to a large number of fixed-structure pressing boards as in traditional production lines. Thickness adjustment can be quickly completed by simply operating the electric actuator, greatly improving production efficiency.

[0022] By cooperating with the bidirectional screw and guide plate, the distance between the two guide plates can be flexibly adjusted according to the different sizes of face paper and back paper. In addition, the built-in spring telescopic rod ensures that the limit wheel is always in contact with the conveyor belt, providing effective limiting and guiding for the conveying of face paper and back paper. This effectively prevents the face paper and back paper from shifting during the conveying process, ensuring the accurate alignment of each layer of material in the gypsum board production process and further improving the production quality of gypsum board.

[0023] The bottom of the feeding tube is connected to a T-shaped tube. The power shaft is driven by a motor, and the T-shaped tube is rotated by gear meshing. When producing gypsum boards of different widths, the positions of the two ends of the T-shaped tube can be flexibly adjusted so that it is located between the two sides of the backing paper, ensuring that the slurry falls accurately between the face paper and the backing paper, thus improving the adaptability of the device to the production of gypsum boards of different widths.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Please see Figure 1 , Figure 2 and Figure 3This embodiment of an adjustable-thickness gypsum board substrate production device includes a conveyor 1, a feeding pipe 2, and several pressing components 3. The feeding pipe 2 is located above one end of the conveyor 1, and a T-shaped pipe 4 is rotatably connected to the bottom end of the feeding pipe 2. The outer surface of the T-shaped pipe 4 has feeding holes 5 evenly distributed along its axial direction. By rotating the T-shaped pipe 4, when producing gypsum boards of different widths, its two ends can be positioned between the two sides of the backing paper. A support frame 6 is provided at one end of the conveyor 1. A mixing tank 7 is fixedly installed at the top of the support frame 6. The bottom of the mixing tank 7 is fixedly connected to the discharge pipe 2. An agitator 8 is rotatably connected to the top of the mixing tank 7. The agitator 8 is located inside the mixing tank 7. The top of the agitator 8 is connected to an external power source. A flow meter 9 is installed in the middle of the discharge pipe 2. An electric valve 10 is installed at the bottom of the mixing tank 7. By controlling the degree of closure of the electric valve 10 and cooperating with the flow meter 9, the discharge amount of slurry can be controlled, thereby controlling the flow rate of the slurry according to the different thicknesses of gypsum boards.

[0035] Please see Figure 1 , Figure 2 and Figure 3 A power plate 11 is fixedly connected to the bottom end of the material drop tube 2. A power shaft 12 is rotatably connected to the bottom of the power plate 11. Gears 13 are fixedly connected to the top ends of the power shaft 12 and the T-tube 4. The two gears 13 mesh with each other. A motor 14 is installed on the upper surface of the power plate 11. The output end of the motor 14 is fixedly connected to the power shaft 12, which can drive the T-tube 4 to rotate, thereby flexibly adjusting the position of both ends of the T-tube 4 according to the needs of producing gypsum boards of different widths.

[0036] Please see Figure 1 , Figure 4 and Figure 5Several pressing components 3 are arranged side-by-side at equal intervals along the conveying direction of the conveyor 1. Each pressing component 3 includes a frame 301. A pressure roller 302 is rotatably connected between the front and rear inner sidewalls of the bottom of the frame 301. Two shaft plates 303 are fixedly connected to the upper surface of the frame 301. A bidirectional lead screw 304 is rotatably connected between the two shaft plates 303. Guide plates 305 are threaded to both ends of the bidirectional lead screw 304. Built-in spring telescopic rods 306 are fixedly connected to both ends of the two guide plates 305. Specifically, the built-in spring telescopic rods 306 are mainly realized by an internal spring or air pressure device. The internal spring accumulates energy when compressed and releases energy when extended, thereby realizing the telescopic function. The design of the telescopic rod is based on the parallelogram principle to ensure stability during the telescopic process and prevent bending or twisting. Each built-in spring telescopic rod 306 has... Perpendicular to the belt of conveyor 1, each built-in spring telescopic rod 306 has a side plate 307 fixedly connected to its movable end. Several limiting wheels 308 are rotatably connected to the side of each side plate 307 closest to conveyor 1. By controlling the distance between the control frame 301 and conveyor 1, the distance between the pressure roller 302 and the face paper can be controlled, thereby controlling the thickness of the gypsum board. The built-in spring telescopic rod 306 ensures that the limiting wheels 308 are always in contact with the belt of conveyor 1. One end of each bidirectional screw 304 is connected to an external power source. By driving the bidirectional screw 304 to rotate through the external power source, the two guide plates 305 can be moved closer or further apart, thereby adjusting the distance between the two guide plates 305. This allows for the limiting of face paper and back paper of different sizes, preventing deviation during conveying and ensuring the production quality of the gypsum board.

[0037] Please see Figure 1 , Figure 4 and Figure 5Both sides of the conveyor 1 are equipped with base plates 15, and electric actuators 16 are installed on the upper surface of both base plates 15. Each electric actuator 16 has a lifting plate 17 fixedly connected to its output end. One end of each frame 301 is fixedly connected to the lifting plate 17 closest to it. The electric actuators 16 can drive the lifting plate 17 to move up and down, thereby driving the pressing assembly 3 to move up and down as a whole, thus controlling the distance between the frame 301 and the conveyor 1, controlling the distance between the pressure roller 302 and the face paper, and ultimately controlling the thickness of the gypsum board. A set of guide rods 18 are fixedly connected to the bottom of each of the two lifting plates 17. Each guide rod 18 is connected to... The adjacent base plates 15 slide and insert vertically. Through the above-mentioned arrangement, the lifting plate 17 can be guided to move up and down, ensuring that the lifting plate 17 remains stable during movement and avoids deviation. This ensures that the pressing assembly 3 can accurately control the thickness of the gypsum board. The upper surface of the two lifting plates 17 near the material drop pipe 2 is fixedly connected to a conveyor frame 19. A composite roller 20 is rotatably connected between the two conveyor frames 19. By setting up a paper feeder above the composite roller 20, the purpose of conveying the face paper is achieved in conjunction with the composite roller 20, so that the pulp is located between the face paper and the back paper. The composite roller 20 can be used to guide the face paper.

[0038] The working principle of the above embodiment is as follows: Gypsum slurry is added to the mixing tank 7, and an external power source is started to drive the stirring blades 8 to rotate, thoroughly mixing the slurry to ensure uniform slurry quality. The conveyor 1 is started, and the backing paper moves continuously under the drive of the conveyor belt. A paper feeder is installed above the composite roller 20, conveying the face paper to the composite roller 20. Guided by the composite roller 20, the face paper is prepared to combine with the slurry and backing paper. According to the production requirements of gypsum boards of different widths, the motor 14 is started. The motor 14 drives the power shaft 12 to rotate, which, through gear 13, drives the T-tube 4 to rotate, causing the T-tube to... The two ends of the tube 4 are located between the two sides of the backing paper to ensure that the slurry falls accurately onto the backing paper. The flow meter 9 at the middle of the discharge tube 2 monitors the flow rate of the slurry in real time. The electric valve 10 at the bottom of the mixing tank 7 controls the degree of closure according to preset parameters. By controlling the degree of closure of the electric valve 10 and coordinating with the monitoring data of the flow meter 9, the amount of slurry discharged is precisely controlled, and the flow rate of the slurry is reasonably controlled according to the different thicknesses of gypsum board. As the conveyor 1 runs, the backing paper continues to move forward, and the slurry flows from T... The material drop holes 5 of the tube 4 evenly drop onto the back paper. Simultaneously, the paper feeder conveys the face paper to the composite roller 20. Under the action of the composite roller 20, the face paper accurately covers the pulp, positioning the pulp between the face paper and the back paper. Depending on the size of the face and back paper, an external power source drives the bidirectional lead screw 304 to rotate, causing the two guide plates 305 to move closer or further apart, adjusting the distance between the two guide plates 305. The built-in spring telescopic rod 306 utilizes an internal spring or pneumatic device to achieve telescopic function. Based on the parallelogram principle, it ensures stability during the telescopic process, ensuring that the bottom of the limit wheel 308 is always in contact with the belt of the conveyor 1. The rotation of the limit wheel 308 connects to... To minimize belt wear, the limiting wheel 308 limits the conveying of the face paper and back paper on both sides, preventing them from shifting during transport and ensuring accurate alignment of each layer of material during gypsum board production. The electric push rod 16 is activated, which drives the lifting plate 17 to move up and down, controlling the distance between the frame 301 and the conveyor 1, thereby controlling the distance between the pressure roller 302 and the face paper, and ultimately controlling the thickness of the gypsum board. As the conveyor 1 continues to run, the pressure roller 302 presses the face paper, slurry, and back paper, so that the gypsum slurry is evenly spread between the face paper and back paper, achieving the expected thickness standard, and finally forming the gypsum board substrate.
