[0019] Please refer to Figures 1-3, an embodiment provided by the present invention: a drying device for paper-faced gypsum board, including a drying frame 1. At the central position of the top end of the drying frame 1, there is a positioning frame 2 located below the paper-faced gypsum board conveying device. On the left side of the positioning frame 2 relative to the top end of the drying frame 1, there is a first side plate 3. A horizontally placed first cylinder 4 is fixed on the first side plate 3. A lower heating plate 5 is connected to the piston rod of the first cylinder 4. On the right side of the positioning frame 2 relative to the top end of the drying frame 1, there is a second side plate 6. A vertically placed second cylinder 8 is installed on the inner wall of the second side plate 6 near one end of the drying frame 1 through a support 7. A supporting frame 9 is connected to the piston rod of the second cylinder 8. A sliding guide rail 10 is provided on the inner wall of the second side plate 6 on one side of the supporting frame 9. A sliding rod 11 is slidably connected in the sliding guide rail 10. One end of the sliding rod 11 extends outside the sliding guide rail 10 and is fixedly connected to the top end of the supporting frame 9. Above the drying frame 1 on one side of the supporting frame 9, there is a bearing seat 12. In order to ensure that the paper-faced gypsum board is not crushed, a fixed sleeve 19 is provided on the top of the bearing seat 12. An elastic member 20 is installed at the central position of the top of the fixed sleeve 19. The bottom end of the elastic member 20 is installed with a T-shaped rod 23. The bottom end of the T-shaped rod 23 extends outside the fixed sleeve 19 and is fixedly connected to the top end of a cross plate 13. In order to appropriately adjust the horizontal position of the upper heating plate above, a first threaded rod 22 is provided at the center of the supporting frame 9. One end of the first threaded rod 22 close to the bearing seat 12 is a sliding rod 21. In order to appropriately adjust the horizontal position of the upper heating plate above, a rotating handle 24 is threadedly connected to the first threaded rod 22. A sliding sleeve 25 that slidably sleeved on the sliding rod 21 is provided at one end of the rotating handle 24 away from the first threaded rod 22; on the outer walls of the supporting frame 9 at both ends of the first threaded rod 22, telescopic rods 26 are installed. The sliding ends of the telescopic rods 26 are fixedly connected to the outer wall of the bearing seat 12. Below the bearing seat 12, there is a cross plate 13. A connecting seat 14 is provided at the bottom end of the cross plate 13. An upper heating plate 15 is provided below the connecting seat 14. At the bottom of the drying frame 1, two third cylinders 16 are arranged at intervals. The piston rods of the third cylinders 16 pass through the positioning frame 2 and are connected to a push plate 17. The two push plates 17 are symmetrically arranged left and right to lift the paper-faced gypsum board on the paper-faced gypsum board conveying device. A controller 18 electrically connected to the first cylinder 4, the second cylinder 8, the third cylinder 16, the lower heating plate 5, and the upper heating plate 15 is further provided in the drying frame 1.

[0020] The present invention also discloses a drying method for a drying device for paper-faced gypsum board, including the above-mentioned drying device for paper-faced gypsum board, characterized in that the specific steps are as follows: S1. First, place this device under the gypsum board conveying equipment, and ensure that the positioning frame 2 is located under one side of the gypsum board conveying equipment, and the conveying direction of the gypsum board conveying equipment is from front to back; S2. During the process of the gypsum board conveying equipment transporting the gypsum board, when the gypsum board is conveyed to the position of the positioning frame 2, after the controller 18 detects the signal at this time, it drives the third cylinder 16 to work, and the push plates 17 on both sides rise upward. After the part of the gypsum board exposed on the gypsum board conveying equipment is fitted, as the third cylinder 16 continues to work, the gypsum board is lifted. Then, it drives the second cylinder 8 and the first cylinder 4 to work simultaneously, moves the lower heating plate 5 below to the lower surface of the lifted gypsum board and fits it, presses down the upper heating plate 15 to fit it with the upper surface of the gypsum board, and then drives the lower heating plate 5 and the upper heating plate 15 to work to heat the upper and lower surfaces of the gypsum board simultaneously for drying treatment; S3. After drying is completed, the second cylinder 8, the first cylinder 4, and the third cylinder 16 are reset, and the dried gypsum board is placed back on the gypsum board conveying equipment to continue the transmission. That's it.

[0021] Preferably, in step S2, the specific method of the lower heating plate 5 and the upper heating plate 15 working to heat the upper and lower surfaces of the gypsum board simultaneously for drying adopts timed drying or temperature-controlled drying. When using temperature-controlled drying, when the drying temperature reaches the preset temperature, that is, the surface of the gypsum board is dried.

[0022] When the embodiment of the present application is in use, first place the device below the paper gypsum board conveying equipment, and ensure that the positioning frame 2 is below one side of the paper gypsum board conveying equipment, and the conveying direction of the paper gypsum board conveying equipment is from front to back; during the process of the paper gypsum board conveying equipment transporting the paper gypsum board, when the paper gypsum board is conveyed to the position of the positioning frame 2, at this time, after the controller 18 detects the signal, it drives the third cylinder 16 to work, and the push plates 17 on both sides rise upwards. After the part of the paper gypsum board exposed on the paper gypsum board conveying equipment is fitted, as the third cylinder 16 continues to work, the paper gypsum board is lifted, and then the second cylinder 8 and the first cylinder 4 are driven to work simultaneously, moving the lower heating plate 5 below to the lower surface of the lifted paper gypsum board and fitting it, and the upper heating plate 15 presses down and fits with the upper surface of the paper gypsum board, and then drives the lower heating plate 5 and the upper heating plate 15 to work to heat the upper and lower surfaces of the paper gypsum board simultaneously for drying treatment; after drying, the second cylinder 8, the first cylinder 4, and the third cylinder 16 return to their original positions, and the dried paper gypsum board is placed back on the paper gypsum board conveying equipment for continued transmission. During the operation process, the second cylinder 8 drives the supporting frame 9 to move downward, so that it drives the connecting seat 14 to move vertically downward. At the same time, one end of the sliding rod 11 is located inside the sliding guide 10 for sliding, so as to limit the lifting amplitude of the supporting frame 9. At this time, the bottom of the upper heating plate 15 precisely contacts the upper surface of the paper gypsum board to press the paper gypsum board tightly, and through the elastic action of the elastic member 20, the phenomenon of the upper heating plate 15 causing pressure damage to the paper gypsum board is reduced. Finally, by manually rotating the handle 19, it drives the threaded cylinder 20 to slide on the outer wall of the first threaded rod 22. After the moving amplitude of the bearing seat 12 is limited by the telescopic rod 26, the distance between the bearing seat 12 and the supporting frame 9 changes, and the horizontal position of the upper heating plate 15 can be adjusted according to requirements so that it can press different widths of paper gypsum boards, further improving the versatility. Therefore, this structural setting can achieve rapid drying operation of the paper gypsum board without flipping the paper gypsum board, and without manual feeding. Just place the device below the existing paper gypsum board conveying equipment, further improving the working efficiency of the equipment. Embodiment 2

[0023] Please refer to Figure 4, the overall structure of the gypsum board drying device disclosed in this embodiment is the same as that of Embodiment 1. The difference is that, in order to achieve the automatic operation function and further improve the work efficiency, an infrared detection sensor 27 for detecting whether the gypsum board is in place is further provided on the drying rack 1. The infrared detection sensor 27 is electrically connected to the controller 18. In this embodiment, the infrared detection sensor 27 is used to detect in real time whether the gypsum board is in place, that is, whether it reaches directly above the positioning frame 2. Once it reaches, the controller 18 drives each device to work, ultimately realizing the automatic operation function and further improving the work efficiency. Embodiment Three
