[0017] See attached Figure 1A corrugated cardboard drying device comprises a box body 1, wherein a plurality of partitions 2 are distributed up and down in the box body 1, a support portion 3 is arranged on the upper surface of the partition 2, and a placement area 4 is arranged on the upper surface of the support portion 3. A plurality of air intake branch pipes 5 are connected to one side of the box body 1, and one end of the plurality of air intake branch pipes 5 respectively corresponds to the support portions 3 of different heights, and the other end is commonly connected to an air intake pipe 6. A hot air unit 7 is arranged at the bottom of the box body 1, and one end of the hot air unit 7, i.e., an air outlet, is connected to the air intake pipe 6. A plurality of exhaust branch pipes 8 are connected to the other side of the box body 1, and the plurality of exhaust branch pipes 8 respectively correspond to the plurality of air intake branch pipes 5 horizontally, and the support portion 3 has a structure that allows the fluid to flow in any direction inside the support portion 3. When the corrugated cardboard a is placed in the placement area 4 on the upper surface of the support part 3, the fluid discharges hot air through the hot air unit 7, enters the upper surface and the lower surface of the corrugated cardboard a through the air inlet pipe 6 and the air inlet branch pipe 5, and when entering the lower surface of the corrugated cardboard a, the hot air is located in the support part 3 and flows and can be blown to the lower surface of the corrugated cardboard a. After drying, the hot air is discharged through the exhaust branch pipe 8, thereby solving the problem in the prior art that the fluidity of the air may be affected by the blockage of the through holes, so as to directly affect the drying effect. In addition, the hot air of the device enters from multiple air inlet branch pipes 5, passes through the multi-layer placement area 4 respectively, and is discharged through the exhaust branch pipe 8, thereby further improving the uniformity of drying.

[0018] Among them, the support part 3 is a plurality of protrusions, which are hemispherical and evenly distributed on the upper surface of the partition 2, so that hot air can flow in the area between the protrusions to avoid blockage, thereby improving the fluidity of the hot air and improving the drying effect.

[0019] The support portion 3 may also be a layer of mesh pads, so that hot air can flow inside the mesh pads to avoid blockage, thereby improving the fluidity of the hot air and thus improving the drying effect. The mesh pads may be composed of multiple layers of steel wire mesh.

[0020] In this embodiment, in order to achieve the purpose of hot air circulation, the other ends of the multiple exhaust branch pipes 8 are commonly connected to the exhaust pipe 9, and the other end of the hot air unit 7, namely the air inlet, is connected to the exhaust pipe 9.

[0021] Specifically, the hot air unit 7 includes a fan 71 and a heating part 72. The fan 71 is arranged at the bottom of the box body 1, and the heating part 72 is located at the outlet of the fan 71. The heating part 72 is a resistance wire or a heating block.

[0022] In this embodiment, the air inlet of the air inlet pipe 6 gradually decreases away from the air inlet of the hot air unit 7, so that the hot air is evenly distributed to different placement areas 4.

[0023] Among them, a through hole 10 is also provided on the partition 2 located above the placement area 4, so that the hot air can flow not only in the horizontal direction but also in the vertical direction, that is, the hot air of the next layer can enter the support part of the upper layer through the through hole 10, thereby improving the air flow effect.
