The first partition 3041, the second partition 3042, the third partition 3043, the fourth partition 3044, and the first side plate 302 are provided with mounting holes 30af, and the mounting holes 30af are arranged opposite to each other. The mounting holes 30af are used to mount the air guide box 601 in the air guide assembly 60, and the air guide box 601 can separate the first space 30aa, the second space 30ab, the third space 30ac, the fourth space 30ad, and the fifth space 30ae from each other without interference, thereby forming closed spaces.

[0046] For the above-mentioned air guide assembly 60, as Figure 2 andFigure 6 As shown, the air guide assembly 60 is arranged in the drying cavity 30a, and is used to buffer the hot air entering the drying cavity 30a. Meanwhile, the air guide assembly 60 can uniformly diffuse the hot air into each drying space in the drying cavity 30a.

[0047] In some embodiments, referring to Figure 7 and Figure 8 , the air guide assembly 60 comprises an air guide box 601, which is provided with an air guide cavity 601b in communication with the hot air cavity in the heating assembly 20.

The air flowing through the heating cavity can flow into the drying cavity 30a through the third through holes 601a. The hot air entering the drying box 30 can be buffered by the air guide box 601, and then uniformly diffused into the drying spaces of the drying cavity 30a through the third through holes 601a on the air guide box 601, and then flows out from the first through holes 301a.

[0048] Optionally, the distance between the bottom of the air guide box 601 and the bottom of the drying cavity 30a of the drying box 30 is 108 mm, and the distance between the two sides of the air guide box 601 and the cavity walls of the drying cavity 30a is 357 mm. In this way, the distribution of the hot air entering the drying cavity 30a is more uniform.

The heat insulation layer is located on the inner side wall of the heating chamber 201. The heat insulation layer can reduce the impact of the high temperature inside the heating chamber 201 on external equipment, and at the same time, it can also reduce the temperature drop inside the heating chamber 201.

[0058] For the aforementioned conveying assembly 40 and fan 50, such as Figure 13 and Figure 14 As shown, the conveying component 40 is disposed on the frame 10. The conveying component 40 is disposed near the first through hole 301a. The side of the conveying component 40 near the first through hole 301a can generate an adsorption force, which can be used to adsorb, fix and convey the items to be dried.

[0059] Please refer to the following for details. Figure 15 The conveying assembly 40 includes an exhaust pipe 401, an adsorption box 402, a connecting pipe 403, a first roller 404, a second roller 405, and a belt 406. The first roller 404 is rotatably connected to one end of the adsorption box 402, and the second roller 405 is rotatably connected to the other end of the adsorption box 402. The belt 406 is fitted over the first roller 404 and the second roller 405. One end of the connecting pipe 403 is connected to the adsorption box 402, and the other end of the connecting pipe 403 is connected to the exhaust pipe 401. The exhaust pipe 401 is connected to one end of a fan 50, and the other end of the fan 50 is connected to the heating box 201. The interior of the adsorption box 402 communicates with the interior of the exhaust pipe 401. During the conveying process of the items to be dried via the belt 406, hot air from the drying chamber 30 flows out through the first through hole 301a. The hot air dries the items on the belt 406. Throughout the drying process, the belt 406 causes the items to be dried to move continuously, so that the hot air can dry different parts of the items, resulting in more uniform drying. At the same time, it can also reduce the deformation of the items due to localized heating.

[0060] In some embodiments, please refer to the following: Figure 16 The exhaust pipe 401 is provided with an exhaust port 4011 communicating with the outside and a rotating plate 4012 for adjusting the diameter of the exhaust port 4011. The rotating plate 4012 is rotatably connected to the exhaust pipe 401. The rotating plate 4012 is provided with multiple rotating ports (not shown). By aligning or offsetting the rotating ports with the exhaust port 4011, the diameter of the exhaust port 4011 can be adjusted, thereby realizing the air volume entering the exhaust pipe 401 from the outside, and thus adjusting the adsorption force generated by the conveying component 40.

Under the action of the fan 50, the plurality of adsorption ports 4021 have adsorption force because the exhaust pipe 401 is in communication with the adsorption box 402, so that the adsorption force can adsorb and fix the articles to be dried on the belt 406. At this time, the articles to be dried are adsorbed on the belt 406 and shield part of the second through holes 4061 on the belt 406, and the second through holes 4061 not shielded by the articles to be dried can suck part of the hot air flowing out of the first through holes 301a into them and transport them into the exhaust pipe 401. The hot air entering the exhaust pipe 401 can also flow through the drying box 30 again under the drive of the fan 50, thereby reducing energy loss. The path of the external medium (wind) flowing through is shown in Figure 15 .

[0062] In some embodiments, the number of the conveying assemblies 40 is multiple groups, and the multiple groups of the conveying assemblies 40 are arranged in a preset direction, and the belts 406 on each of the conveying assemblies 40 are located on the same horizontal plane. The user can open a certain number of the conveying assemblies 40 according to the size of the actual articles to be dried, and can open the adjusting plates 6021 (open state) at different positions according to the different positions of the articles to be dried, so that the hot air enters the corresponding space and flows out from the corresponding first through holes 301a, thereby reducing the waste of resources. For example, if the distance between each group of conveying assemblies 40 is 20 cm, and the multiple groups of the conveying assemblies 40 are arranged along the length direction of the articles to be dried, if the length of the articles to be dried is 40 cm, at this time, the user needs to open three groups of the conveying assemblies 40 arranged adjacent to each other for adsorption and fixation and conveying the articles to be dried. If at this time, the articles to be dried are placed below the first space 30aa and the second space 30ab, the user only needs to open the first adjusting plate 60211 and the second adjusting plate 60212, so that the hot air enters the first space 30aa and the second space 30ab and flows out from the first through holes 301a in the first space 30aa and the second space 30ab, thereby realizing drying the articles to be dried below the first space 30aa and the second space 30ab.

[0063] For the above-mentioned temperature sensor and control assembly 70, as Figure 2As shown, the temperature sensor is located at the joint between the air duct body 601 and the drying box body 30, and the control assembly 70 is electrically connected with the temperature sensor, the heating assembly 20 and the adjusting assembly 602. The temperature sensor is used for detecting the temperature of the hot air entering the drying cavity 30a and transmitting the detected temperature signal to the control assembly 70. When the temperature signal is higher than a preset temperature value or lower than a preset temperature value, the control assembly 70 can adjust the heating temperature of the heating assembly 20 according to actual needs. In addition, the control assembly 70 can also control the adjusting assembly 602 to dry different positions of the to-be-dried articles and control the adjusting assembly 602 to adjust the air speed of the hot air entering the drying cavity 30a.

[0064] In the embodiment of the present application, the rack 10, the heating assembly 20, the drying box body 30, the conveying assembly 40 and the fan 50 are arranged. The heating assembly 20 comprises a heating box body 201 arranged on the rack 10, the heating box body 201 is provided with a heating cavity, the drying box body 30 is arranged on the rack 10 and located close to the upper end of the rack 10, the drying box body 30 is provided with a drying cavity 30a, the drying cavity 30a is communicated with the heating cavity, the conveying assembly 40 is arranged on the rack 10, the conveying assembly 40 comprises an air suction pipe 401, the conveying assembly 40 is arranged close to the first through hole, the side of the conveying assembly 40 close to the first through hole can generate a suction force, the fan 50 is arranged on the rack 10, one end of the fan 50 is connected with the air suction pipe 401, and the other end of the fan 50 is connected with the heating box body 201. Compared with the infrared drying in the prior art, the paperboard is dried by hot air, the hot air can uniformly heat the paperboard, thereby reducing the difference between the actual expansion rates of the surface and the core paper of the paperboard, reducing the warping deformation of the paperboard. Meanwhile, the fan 50 drives external medium (air) to flow through the heating assembly 20 and the drying box body 30, part of the external medium (air) can flow back to the fan 50 through the air suction pipe 401 of the conveying assembly 40, thereby forming a semi-closed loop drying system, reducing energy loss and resource waste.
