The hot air blower 25 inhales the outside air through the connecting pipe 26 close to the discharge port 4, and then the motor inside the hot air blower 25 heats the inhaled air, and then it is discharged into the funnel 24 through multiple air ducts. The heated air continues to rise to dry the wet carton, and the output end of the telescopic rod 10 is controlled to move vertically downward. The U-shaped plate 11 is fixedly connected to the output end of the telescopic rod 10, and the U-shaped plate 11 will move vertically downward until the support rod 13 below the U-shaped plate 11 contacts the carton. The output end of the telescopic rod 10 continues to be controlled to move vertically downward, the spring 12 is compressed, and the support rod 13 slides on the inner wall of the fixed groove. The elastic force of the spring 12 will press the carton to achieve the purpose of limiting the position of the carton. Then the tool at the bottom end of the telescopic rod 10 abuts against the carton, and then the tool will complete the cutting of the carton. After the cutting is completed, the rotating shaft 22 is controlled to rotate again, so that the carton after cutting passes through the discharge port 4 and falls into the storage box 5, thereby achieving the purpose of facilitating the unloading of the carton.
