[0028] In one embodiment, a metal wire mesh is embedded in the bottom surface of the heating shell 19, and the fan 20 consists of a drive motor and an impeller mounted on its output end. This structure is beneficial for the uniform airflow of the heating shell 19.

[0029] Working principle: First, by moving the printing roller 17 up and down, the slider 25 on the slide block 14 slides inside the slide rail 13. When the printing roller 17 is adjusted to a suitable height, the swivel knob 24, which is threaded to the slider 25, is rotated so that the knob end of the swivel knob 24 abuts against the surface of the slide rail 13, thereby adjusting and locking the height of the printing roller 17. During printing, the liquid pump 7 on the surface of the ink supply tube 6 is activated, causing the ink in the ink tank 5 to be pumped into the inkjet tube 11. Then, several inkjet nozzles 16 on the inkjet tube 11 spray the ink onto the surface of the printing roller 17. At this time, the brush 12 on the support plate 10 evenly coats the surface of the printing roller 17 with the ink sprayed on it. The printing roller 17 is driven to rotate by the motor 15. During the drying stage, the pattern is printed on the surface of the cardboard conveyed on the conveyor belt 2. When drying, the fans 20 and heating wires 21 installed in the two heating shells 19 are activated, causing the fans 20 to blow the heat generated by the heating wires 21 toward the conveyor belt 2. At this time, since there is an intermediate shell 22 connecting the two heating shells 19 and the bottom of the intermediate shell 22 is open, the hot air inside the two heating shells 19 is introduced into the intermediate shell 22 by the blowing action of the fans 20 during the working stage, and then discharged from the opening on the bottom of the intermediate shell 22. This allows the hot air generated by the heating shells 19 to fully cover the cardboard conveyed on the conveyor belt 2, achieving full and thorough drying of the cardboard, facilitating the subsequent winding of the cardboard and the forming of the paper cup, and preventing the inside of the paper cup from being contaminated by ink.
