Description

Technical Field

[0001] This application relates to the field of hollow board production line technology, and in particular to a fiberboard production line that incorporates vacuum extrusion and microwave curing. Background Technology

[0002] The manufacturing process of hollow boards involves feeding inorganic materials into an extruder through a hopper, extruding them through a molding device, and then conveying them along a conveyor line. During the conveying process, the materials are cut to form the required hollow boards (divided into dry boards and wet boards). Afterward, a stacking mechanism places them in a predetermined position.

[0003] For hollow core boards with special performance requirements, the requirements for strength and durability are even higher, and the above-mentioned process cannot meet the performance requirements of this type of hollow core board. Summary of the Invention

[0004] To improve the strength and durability of hollow fiberboard, this application provides a fiberboard production line that includes vacuum extrusion and microwave curing.

[0005] The fiberboard production line containing vacuum extrusion and microwave curing provided in this application adopts the following technical solution:

[0006] A fiberboard production line comprising vacuum extrusion and microwave curing, including

[0007] A conveying assembly, comprising two parallel support plates, with a plurality of rollers rotatably disposed between the two support plates;

[0008] A heating assembly includes a sealing cover that covers the conveying assembly, and a microwave heater is disposed inside the sealing cover for heating the hollow plate.

[0009] By adopting the above technical solution, after the hollow board is fed into the sealing cover by the conveying assembly, the microwave heater heats the hollow board. The microwave heater emits electromagnetic waves that interact with the molecules in the hollow board. Under the influence of the microwave electromagnetic field, the molecules inside the hollow board undergo high-frequency vibration and rotation. This vibration and rotation leads to friction and collision within the molecules, thereby generating heat energy. This ensures that the material in the hollow board is heated evenly, improving the physical properties of the hollow board, thus increasing its strength and durability, and reducing the possibility of deformation and damage.

[0010] Preferably, the conveying assembly includes a first conveying area and a second conveying area, both of which are equipped with heating components, and a flipping component for flipping the hollow board is provided between the first and second conveying areas.

[0011] By adopting the above technical solution, after the hollow board passes through the heating component in the first conveying area and the surface of the hollow board is heated, the flipping component flips the hollow board over and enters the heating component in the second conveying area to heat the other side of the hollow board, which further improves the strength and durability of the hollow board and reduces the possibility of deformation and damage to the hollow board.

[0012] Preferably, the flipping assembly includes a first support frame and a second support frame rotatably mounted on a support plate. Each of the first and second support frames has a plurality of support rods fixedly connected to support the hollow plates. The bottom of the support plate is provided with a drive assembly for driving the first and second support frames to rotate.

[0013] By adopting the above technical solution, the driving component drives the first support frame and the second support frame to rotate in opposite directions. When the first support frame rotates, the support rod supports the hollow plate, so that the hollow plate leans against the first support frame. When the first support frame and the second support frame rotate to be perpendicular to the support plate and in contact with it, the first support frame and the second support frame are close together, thereby clamping the hollow plate between the first support frame and the second support frame. The first support frame continues to rotate in the direction of the second support frame, and the second support frame changes its rotation direction, so that the hollow plate leans against the second support frame. At this time, the first support frame rotates in the opposite direction to the initial position on the first conveying area. When the second support frame rotates to the initial position on the second conveying area, the hollow plate is flipped and falls onto the roller, thereby facilitating the heating of the other side of the hollow plate.

[0014] Preferably, a support frame is fixedly connected to the bottom of the support plate, and the driving assembly includes a first driving member and a second driving member rotatably mounted on the support frame. Both the first driving member and the second driving member are telescopic members. The output end of the first driving member is connected to the first support frame, and the output end of the second driving member is connected to the second support frame.

[0015] By adopting the above technical solution, when the output end of the first driving component extends, the first support frame can rotate towards the second support frame; when the output end of the first driving component shortens, the first support frame rotates away from the second support frame. Similarly, when the output end of the second driving component extends, the second support frame can rotate towards the first support frame; when the output end of the second driving component shortens, the second support frame rotates away from the first support frame.

[0016] Preferably, the conveying assembly is equipped with a correction component for adjusting the position of the hollow plate.

[0017] By adopting the above technical solution, the correction component can adjust the moving position of the hollow plate, reducing the possibility of the hollow plate shifting and falling off the roller.

[0018] Preferably, the correction assembly includes a baffle fixedly connected to a support plate, a first panel hinged to the inner wall of the baffle, a second panel hinged to the end of the first panel away from the baffle, and a drive source provided on the baffle to simultaneously drive the first panel and the second panel to move.

[0019] By adopting the above technical solution, the drive source drives the first panel and the second panel to move. The second panel is always set parallel to the baffle, and the first panel is set at an angle between the second panel and the baffle. The drive source can adjust the distance between the two second panels so that the width of the hollow plate is the same as the distance between the two second panels. When the offset hollow plate is offset on the roller, the first panel plays a guiding role for the hollow plate, thereby adjusting the position of the hollow plate so that the hollow plate can pass between the two second panels, thereby reducing the possibility of the hollow plate detaching from the roller and ensuring the normal transportation of the hollow plate.

[0020] Preferably, the side of the first panel and the second panel facing away from the baffle is rotatably connected to a plurality of sliding columns.

[0021] By adopting the above technical solution, the sliding column can reduce the situation where the hollow plate stops moving on the roller due to excessive friction between the hollow plate and the first or second panel, or the situation where the conveying speed of the hollow plate decreases due to excessive friction between the first panel and the hollow plate.

[0022] Preferably, the driving source is an electric telescopic rod, which is fixedly connected to the baffle, and the telescopic end of the driving source passes through the baffle to push the second panel to move.

[0023] By adopting the above technical solution, when the electric telescopic rod pushes the second panel to move away from the baffle, the second panel can drive the first panel to move, so that the first panel and the second panel can form a suitable channel for the hollow panel to pass through.

[0024] Preferably, the correction components are respectively located at the inlet of the heating component in the first conveying area and at the outlet of the heating component in the second conveying area.

[0025] By adopting the above technical solution, the position of the hollow board is adjusted between the heating components in the first conveying area to improve the heating uniformity of the hollow board. When the hollow board comes out of the heating components in the second conveying area, the position of the hollow board is adjusted to facilitate the collection of the processed hollow board.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. After the hollow core sheet is conveyed into the sealed cover by the conveyor assembly, a microwave heater heats the hollow core sheet. The microwave heater emits electromagnetic waves that interact with the molecules in the hollow core sheet. Under the influence of the electromagnetic field of the microwave, the molecules inside the hollow core sheet vibrate and rotate at high frequency. This vibration and rotation leads to friction and collisions within the molecules, thereby generating heat energy. This ensures that the material in the hollow core sheet is heated evenly, improving the physical properties of the hollow core sheet, thus increasing its strength and durability, and reducing the possibility of deformation and damage.

[0028] 2. After the hollow board passes through the heating component in the first conveying area and its surface is heated, the flipping component flips the hollow board over and enters the heating component in the second conveying area to heat the other side of the hollow board, which further improves the strength and durability of the hollow board and reduces the possibility of deformation and damage.

[0029] 3. The sliding column can reduce the situation where the hollow plate stops moving on the roller due to excessive friction between the hollow plate and the first or second panel, or the situation where the conveying speed of the hollow plate decreases due to excessive friction between the first panel and the hollow plate.

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0035] This application discloses a fiberboard production line that includes vacuum extrusion and microwave curing.

[0036] A fiberboard production line incorporating vacuum extrusion and microwave curing, as described above. Figure 1 It includes a conveying assembly 1, which includes two parallel support plates 11, and a plurality of rollers 12 are rotatably arranged between the support plates 11. The rollers 12 are used to convey the hollow plate.

[0037] Reference Figure 1 The conveying assembly 1 includes a first conveying area 13 and a second conveying area 14. Heating assemblies 2 are installed on both the first and second conveying areas 13 and 14. Each heating assembly 2 includes a sealing cover 21 covering the conveying assembly 1 and a microwave heater 22 (not shown in the figure) installed within the sealing cover 21. The microwave heater 22 emits electromagnetic waves that interact with the molecules in the hollow plate. Under the influence of the microwave electromagnetic field, the molecules in the hollow plate vibrate and rotate at high frequency. This vibration and rotation leads to internal friction and collisions within the molecules, generating heat energy. This ensures that the material in the hollow plate is heated evenly, improving the physical properties of the hollow plate, thereby increasing its strength and durability, and reducing the possibility of deformation and damage.

[0038] Reference Figure 1 and Figure 2 A correction assembly 3 is provided on both the first conveying area 13 and the second conveying area 14. The correction assembly 3 includes a baffle 31 fixedly connected to the support plate 11. A first panel 32 is hinged to the side of the baffle 31 facing the roller 12. A second panel 33 is hinged to the end of the first panel 32 away from the baffle 31. A plurality of sliding columns 34 are rotatably connected to the side of the first panel 32 and the second panel 33 away from the baffle 31. The sliding columns 34 are arranged perpendicular to the axis of the roller 12. A drive source 35 is fixedly connected to the baffle 31 to drive the first panel 32 and the second panel 33 away from the baffle 31. The drive source 35 is an electric telescopic rod.

[0039] When the hollow panel deviates from its position on the conveying assembly 1, the drive source 35 extends and pushes the first panel 32 and the second panel 33 away from the baffle 31 until the distance between the two opposing second panels 33 is equal to the width of the hollow panel. At this point, the hollow panel first contacts the sliding post 34 on the first panel 32. The sliding post 34 adjusts the orientation of the hollow panel, reducing the frictional resistance between the first panel 32 and the hollow panel, allowing the hollow panel to adjust its orientation during normal movement and pass between the two second panels 33. The correction assembly 3 adjusts the trajectory of the hollow panel on the conveying assembly 1, reducing the possibility of the hollow panel falling off the conveying assembly 1.

[0040] Reference Figure 1 and Figure 3The conveying assembly 1 is equipped with a tilting assembly 4. The tilting assembly 4 includes a support frame 41 located at the bottom of the conveying assembly 1. The support frame 41 spans the first conveying area 13 and the second conveying area 14. One end of the support frame 41 is fixedly connected to the support plate 11 of the first conveying area 13, and the other end of the support frame 41 is fixedly connected to the support plate 11 of the second conveying area 14. The tilting assembly 4 includes a fixing block 42 fixedly connected to the support plate 11. A first support frame 43 and a second support frame 44 are rotatably connected to the fixing block 42. The first support frame 43 is placed on the support plate 11 of the first conveying area 13, and the second support frame 41 is placed on the support plate 11 of the second conveying area 14. Both the first support frame 43 and the second support frame 44 are provided with a plurality of support rods 45 for supporting the hollow plate. The support rods 45 are parallel to the rollers 12 and placed between adjacent rollers 12.

[0041] Reference Figure 2 and Figure 3 The support frame 41 is equipped with a drive assembly 5 for driving the rotation of the first support frame 43 and the second support frame 44. The drive assembly 5 includes a first drive member 51 and a second drive member 52. The first drive member 51 is rotatably mounted on the support frame 41 at the bottom of the first conveying area 13, and its output end is fixedly connected to the support rod 45 on the first support frame 43. The second drive member 52 is mounted on the support frame 41 at the bottom of the second conveying area 14, and its output end is fixedly connected to the support rod 45 on the second support frame 44. Both the first drive member 51 and the second drive member 52 are hydraulic cylinders.

[0042] After the hollow board is heated by the heating component 2 in the first conveying area 13, one side of the hollow board is uniformly heated. The conveying component 1 drives the hollow board to continue moving. When the hollow board moves to the fixed block 42, the driving component 5 simultaneously drives the first support frame 43 and the second support frame 44 to rotate. The first driving component 51 rotates and extends its output end, so that the first support frame 43 rotates toward the second support frame 44. During the rotation of the first support frame 43, the support rod 45 on the first support frame 43 supports the hollow board, and the hollow board stands on the fixed block 42 and leans against the first support frame 43. The second driving component 52 rotates and extends its output end, causing the second support frame 44 to rotate toward the first support frame 43. When both the first support frame 43 and the second support frame 44 rotate to be perpendicular to the support plate 11, the first support frame 43 and the second support frame 44 come into close contact, thereby clamping the hollow plate between the first support frame 43 and the second support frame 44, thus providing support for the hollow plate and reducing the possibility of the hollow plate falling.

[0043] The first support frame 43 continues to rotate toward the second support frame 44, and the output end of the second drive member 52 shortens, so that the hollow plate leans against the second support frame 44. At this time, the first support frame 43 rotates in the opposite direction to the initial position on the first conveying area 13. When the second support frame 44 rotates to the initial position on the second conveying area 14, the heated side of the hollow plate falls onto the roller 12 and is sent to the heating component 2 in the second conveying area 14 through the roller 12 to heat the other side of the hollow plate, so that both sides of the vacuum plate can be heated, which further improves the strength and durability of the hollow plate and reduces the possibility of deformation and damage to the hollow plate.

[0044] The implementation principle of a fiberboard production line in this application, which includes vacuum extrusion and microwave curing, is as follows: When the hollow board is running in the first conveying zone 13, the correction component 3 can adjust the movement trajectory of the hollow board, reducing the possibility of the hollow board falling off the conveying component 1. The hollow board enters the heating component 2, where the heating component 2 uniformly heats one side of the hollow board, improving its strength and durability. Then, the flipping component 4 flips the hollow board over, and the hollow board enters the heating component 2 in the second conveying zone 14, thereby uniformly heating the other side of the hollow board, further improving its strength and durability and reducing the possibility of deformation and damage. Finally, the hollow board enters the correction component 3 in the second conveying zone 14, where its position is adjusted again, and then it is conveyed to the loading equipment.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
