[0002] After the printing of paper and plastic products is completed, they need to be quickly dried by an air-drying device. The authorization announcement number CN220298099U discloses an environmentally friendly air-drying device for printing paper and plastic products. The device installs filter cotton on the inner side of the induced draft duct and connects the filter cotton between the transmission rollers.
