[0034] Then, the fan 51 can be started to transport gas into the drying chamber 1 through the blowing pipe 52 , thereby blowing the heat generated by the heating coil 2 into the drying chamber 1 through the heat dissipation holes 13 .

[0035] Reference Figure 2 and Figure 3 A placement plate 3 is provided in the drying chamber 1, and the placement plate 3 is arranged in a rectangular parallelepiped shape. A driving assembly 4 for driving the placement plate 3 to slide in the drying chamber 1 is installed on the placement plate 3.

[0036] The driving assembly 4 includes two pairs of pulleys 41 rotatably connected to the lower end of the placement plate 3, and a same driving motor 42 is arranged between the same pair of pulleys 41. The output shaft of the driving motor 42 is coaxially arranged with the pulley 41 and fixedly connected to the pulley 41. The driving motor 42 is fixedly connected to the lower end of the placement plate 3.

[0037] In order to improve the sliding stability of the pulley 41, two slide rails 9 are provided in the drying bin 1. The slide rails 9 are laid on the ground and arranged along the length direction of the drying bin 1. The pulley 41 is slidably connected to the slide rails 9.

[0038] Then, the driving motor 42 is started to drive the pulley 41 to slide on the slide rail 9 , so that the placement plate 3 moves in the drying chamber 1 .

[0039] A fixing frame 6 is disposed above the placement plate 3, and the fixing frame 6 is disposed parallel to the placement plate 3. A connecting mechanism 7 for connecting the fixing frame 6 and the placement plate 3 is disposed between the fixing frame 6 and the placement plate 3.

[0040] The connecting mechanism 7 includes four connecting rods 71 ​​arranged parallel to each other, and the connecting rods 71 ​​are respectively located at the four corners of the placement plate 3. One end of the connecting rod 71 is fixedly connected to the upper end surface of the placement plate 3, and the other end of the connecting rod 71 passes through and is slidably connected to the fixed frame 6. The connecting rod 71 is provided with a limit assembly 72 for fixing the fixed frame 6 on the connecting rod 71.

[0041] The limiting assembly 72 includes eight nuts 721 , and two nuts 721 are provided on each connecting rod 71 . The two nuts 721 are respectively located at the upper and lower ends of the fixing frame 6 and abut against the fixing frame 6 , and the nuts 721 are threadedly connected to the connecting rod 71 .

The fixing assembly 8 includes a receiving net 82 and a plurality of fixing rods 81. The receiving net 82 is fixedly connected in the fixing frame 6, and the fixing rods 81 are fixedly connected to the upper end surface of the placement plate 3 by bolts. The plurality of fixing rods 81 are parallel to each other and the spacing between two adjacent fixing rods 81 is greater than the thickness of the required dried corrugated cardboard. The length direction of the fixing rod 81 is perpendicular to the laying direction of the slide rail 9. Each fixing rod 81 is provided with two connecting ropes 83, and the connecting ropes 83 have a certain elasticity. The two connecting ropes 83 are respectively located at the two ends of the fixing rod 81.

At the same time, it is necessary to pay attention to and make the wavy corrugated mouth of the corrugated paperboard face one side of the heating coil 2, so that the dry hot air discharged from the heat dissipation hole 13 can enter the interior of the corrugated paper.

[0045] Then, the distance between the fixing frame 6 and the placing plate 3 is adjusted by the nut 721, so that the fixing frame 6 abuts against the upper part of the corrugated board. Then, the heating coil 2, the fan 51 and the driving motor 42 are started. The fan 51 blows the dry hot air to the corrugated paper in the corrugated board, so that the dry hot air enters the corrugated paper in the corrugated board. The inside of the corrugated paper is dried, and at the same time, the driving motor 42 drives multiple corrugated boards to move. In this way, the corrugated paper inside the corrugated board can be dried better.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
