[0030] Reference Figures 1 to 4 This invention describes a cardboard drying apparatus according to an embodiment of the present invention.

[0031] Reference Figures 1 to 4 In some embodiments, the cardboard drying apparatus includes a housing 10, a circulating drying mechanism 20, and a rotary conveying mechanism 30. The housing 10 has an inlet 11 and an outlet 12 on its front, and an air inlet 13 on its top for introducing external air. The circulating drying mechanism 20 is fixed to the top of the housing 10 and includes a heating component 21, an air supply component 22, and an air circulation component 23. The air circulation component 23 communicates with the interior of the housing 10 through the air inlet 13, forming a closed-loop hot air circuit. The rotary conveying mechanism 30 is installed inside the housing 10, directly below the circulating drying mechanism 20, and includes a rotating component 31, a conveying component 32, and a clamping component 33. The conveying assembly 32 transports the cardboard 1 horizontally from the input port 11 to the output port 12 by rotating the roller 322. The clamping assembly 33 clamps the cardboard 1 by vertical movement of the lifting plate 332 and, together with the rotating assembly 31, achieves a 180° flip, so that both sides of the cardboard 1 are exposed to the hot air of the circulating drying mechanism 20 in sequence, thus achieving double-sided drying in a single transport.

[0032] It should be noted that, referring to Figures 1 to 4 In some embodiments, the air circulation component 23 of the circulating drying mechanism 20 includes two sets of arc-shaped circulating air ducts 231 and a central heating air duct 232. The heating component 21 is located at the lower end of the heating air duct 232, and the air supply component 22 (such as a centrifugal fan) is installed at the upper end of the heating air duct 232. During operation, the air supply component 22 draws in external air through the air inlet 13, which flows through the heating component 21 to form a high-temperature airflow, and blows vertically downward along the heating air duct 232 onto the cardboard 1 on the rotating conveyor mechanism 30. After the hot air penetrates the cardboard 1, it flows back to the top of the heating air duct 232 through the arc-shaped circulating air ducts 231 on both sides, forming a circulation path.

[0033] Reference Figures 1 to 4 In some embodiments, the clamping assembly 33 of the rotating transport mechanism 30 includes four hydraulic lifting components 331 and a perforated lifting plate 332. The hydraulic lifting components 331 are symmetrically installed at the four corners of the transport bracket 321, and the lifting plate 332 is connected to the hydraulic lifting components 331 via a telescopic rod. When the cardboard 1 is transported from the input port 11 to the designated position by the roller 322, the upper surface of the cardboard 1 is dried first. When the hydraulic lifting components 331 drive the lifting plate 332 to press down, the lifting plate 332 with the perforated structure (such as a mesh plate) and the roller 322 together clamp the cardboard 1 to prevent it from shifting during the flipping process. The rotating assembly 31 (such as a rotating shaft driven by a servo motor) drives the entire transport assembly 32 to rotate 180°, at which time the lower surface of the cardboard 1 is dried. After the lower surface of the cardboard 1 is dried, the rotating assembly 31 drives the entire transport assembly 32 to rotate 180° again, so that the upper surface of the cardboard 1 faces upward and then continues to be transported to the output port 12. The hollow structure design allows hot air to penetrate the lifting plate 332, avoiding obstruction of the drying area.

[0034] Reference Figure 4 In some embodiments, the rollers 322 of the conveying assembly 32 are arranged on the conveying support 321 at a distance of at least one roller diameter. This spacing design balances the supporting strength of the cardboard 1 and the efficiency of hot air penetration: the gap between adjacent rollers 322 allows hot air to pass through the rollers 322 to directly dry the cardboard 1 during reverse drying, forming convection with the downdraft airflow of the top circulating drying mechanism 20, eliminating drying dead zones. At the same time, the surface of the rollers 322 is coated with a silicone layer to increase friction and reduce vibration during the transport of the cardboard 1.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
