[0002] Cardboard is also called paperboard. It is a thick paper sheet made of various pulps and interwoven with fibers. The difference between cardboard and paper is usually distinguished by basis weight and thickness. Generally, paper with a basis weight of more than 250g / m and a thickness of more than 0.5mm is called cardboard (in other words: paper with a thickness of more than 0.1mm is generally called cardboard. Generally, paper with a basis weight of less than 250g / m is considered paper, and paper with a basis weight of 250g / m or more is considered cardboard). Cardboard is an indispensable part of cartons. After drying, cardboard can be produced into cartons through cutting, bonding and other steps.

[0003] A Chinese patent with publication number CN219415486U discloses a drying device for carton paperboard production, which belongs to the technical field of carton paperboard production, and comprises: a drying box for drying carton paperboard, a support sliding frame arranged in the inner cavity of the drying box for holding carton paperboard, and a support base arranged at the bottom end of the drying box; a rotating motor is fixedly installed on one side of the support base, the output shaft of the rotating motor passes through the inner cavity of the support base and is fixedly connected to a threaded rod, both ends of the threaded rod are fixedly connected to ball bearings and are rotatably connected to the inner wall of the support base through the ball bearings, the rod body of the threaded rod is threaded with a threaded barrel, the outer wall of the threaded barrel is fixedly connected to a support block, and the top of the support block is fixedly connected to a mounting rod.

When the end of the cardboard is inserted between the two driven rotating rollers at the discharge port, one of the driven rollers can be driven to rotate by starting the second stepper motor, so that the cardboard is discharged from the drying box. In this way, the loading and unloading of the cardboard can be completed quickly, which is conducive to improving the overall drying efficiency of the device;

[0013] In the above mechanism, the active roller is the same length as the feed port, and the feed port can be sealed to a certain extent by the two active rollers when conveying the cardboard.
