An adjustment component 43 is provided between the fixed frame 41 and the movable frame 44.

[0023] In this embodiment, when in use, the adjustment component 43 can be controlled according to the thickness of the cardboard. The adjustment component 43 can control the movable frame 44 to move toward the side close to the fixed frame 41. Then, the movable frame 44 cooperates with the auxiliary belt 47 to restrain the cardboard. The driving component 45 can control the movable frame 44 to transport the cardboard, thereby realizing vertical transportation of multiple groups of cardboards, improving drying uniformity, and simultaneously transporting two groups of cardboards of different sizes for drying.

[0024] Specifically, the movable frame 44 includes a moving frame 441, which is slidingly connected to the surface of the slide rod 42. The inner wall of the moving frame 441 is rotatably connected to multiple transmission rollers 442. The multiple transmission rollers 442 are arranged at equal intervals, and the surfaces of the multiple transmission rollers 442 are installed with transmission belts 443.

[0025] In this embodiment, when the movable frame 44 is being transported, the driving assembly 45 can drive the transmission roller 442 to rotate, and the transmission roller 442 thereby drives the transmission belt 443 to move, and the transmission belt 443 can cooperate with the auxiliary belt 47 to transport the cardboard.

[0026] Specifically, the drive assembly 45 includes a motor 451 , which is fixedly connected to the surface of the fixing frame 41 , a transmission shaft 453 is fixedly connected to the surface of the transmission roller 442 , and a transmission belt 452 is installed between the output end of the motor 451 and the transmission shaft 453 .

[0027] In this embodiment, when the driving component 45 is driving, it mainly turns on the motor 451, and the motor 451 can drive the transmission shaft 453 and the transmission roller 442 to rotate through the transmission belt 452.

[0028] Specifically, the adjustment component 43 includes two screws 431, and the two screws 431 are rotatably connected to the two side surfaces of the fixed frame 41 respectively. The surface of the movable frame 441 is fixedly connected with a connecting seat 432, and the screws 431 are rotatably connected to the inner wall of the connecting seat 432. The two sets of screws 431 can be rotated to control the movement of the two sets of movable frames 441, and cardboards of the same or different sizes can be restricted.

[0029] Specifically, a plurality of limiting rods 48 are fixedly connected to the surfaces of the movable frame 441 and the fixed frame 41 , respectively, and the plurality of limiting rods 48 are arranged at equal intervals.

The intercepting surface of the limiting rod 48 on the fixed frame 41 is close to the contact surface of the auxiliary belt 47, but is not flush with the auxiliary belt 47.

[0032] Working principle: When drying, two sets of screws 431 can be rotated according to the size of the cardboard. The screws 431 drive the movable frame 441 to move to the side close to the fixed frame 41 through the connecting seat 432, and then the transmission belt 443 and the auxiliary belt 47 clamp the cardboard. Then, the motor 451 is turned on and the motor 451 is operated. The motor 451 drives the transmission shaft 453 and a set of transmission rollers 442 to rotate through the transmission belt 452. The transmission rollers 442 cooperate to drive the transmission belt 443 and multiple sets of transmission rollers 442 to rotate. Then, the transmission belt 443 cooperates with the auxiliary belt 47 to transport the cardboard, realizing vertical transportation and simultaneously transporting two sets of cardboards into the drying chamber 3 for drying. When the cardboards are too long during transportation, multiple sets of limit rods 48 can serve to intercept and support the cardboards. After the two sets of cardboards are transported to the drying chamber 3, they can be dried in the drying chamber 3. The vertical cardboards can be dried more evenly, thereby improving the uniformity of drying and the efficiency of the cardboard drying process.
