Beneficial effects of the present invention: a humidification system designed by the present invention for humidifying the inner lining paper with saturated steam uses a dryer to pre-process the inner lining paper, so that the inner lining paper can be fully dried before entering the steam circulation chamber, Thus, moisture can be sufficiently absorbed in the steam circulation chamber. Considering that the inner lining paper needs to have a lower temperature when it enters the steam circulation chamber, so that when the inner lining paper enters the steam circulation chamber, water molecules can condense on the inner lining paper, so set the The first cooling cylinder and the second cooling cylinder are on the transmission path of the inner lining paper for cooling the dried inner lining paper. When the inner lining paper absorbs moisture in the steam circulation chamber, both sides of the inner lining paper can be fully exposed to the high moisture environment in the steam circulation chamber, so as to fully and uniformly absorb the moisture. The movement of the inner lining paper between the various components is driven by the transmission device. And after the inner lining paper leaves the middle-end humidification system, when it is collected at the rear-end storage system, the moisture detection probe is used to detect the moisture content of the inner lining paper, to check whether the moisture of the inner lining paper meets the standard, and the data is processed. The electrical signal is converted at the machine to be displayed on the display screen, so that the relevant technical personnel can adjust the steam production power in the steam chamber in real time according to the moisture in the processed lining paper, so as to realize the corresponding adjustment and make Moisture control of the inner liner is always up to standard.
