Membrane is unfolded；Roller 2 is crossed for adjusting the tension of nonwoven cloth diaphragm；Applicator roll 3 is used for coating liquid in nonwoven cloth diaphragm
One side surface, applicator roll 3 are also equipped with to the pressure roller 10 of arrangement, nonwoven cloth diaphragm is pressed on pressure roller 10 when walking, that is, presses
Roller 10 by membrane pressure and membrane is oriented to, and masking liquid is adhered to membrane surface by applicator roll 3 by way of rotating and being coated with.
Drying device includes several drying boxes sequentially passed through from the nonwoven cloth diaphragm that guide roller 4 transmits, wherein nonwoven
Cloth diaphragm is sent to next drying box in a floating manner in the first drying box 11 near guide roller 4.The suspension,
I.e. in the first drying box 11, nonwoven cloth diaphragm is not in contact with other equipment facility.Compared to traditional technology in drying
For the technology that roller is used in case, the construction of embodiment, nonwoven cloth diaphragm is not in contact with roller, therefore nonwoven cloth diaphragm
The phenomenon that liquid of middle coating will not be adhered to because of infiltration on roller.By first time it is dry after non-woven fabrics every
Masking liquid relatively dry in film, therefore there will be no phenomenon of osmosis after the drying box at rear is transmitted to, subsequent drying
Case is realized without the mode of suspension.
It is further preferred that the forward and backward side of the first drying box 11 is equipped with delivery roll 12.Along transmission in first drying box 11
Direction is equipped with the lower jet thrust 13 of several jet directions upward, and nonwoven cloth diaphragm transmits above lower jet thrust 13.Work as nonwoven
When cloth diaphragm reaches lower 13 top of jet thrust, the lower jet thrust 13 for continuing jet in the transmit direction blows nonwoven cloth diaphragm upwards
It rises so that nonwoven cloth diaphragm will not fall, and be formed " suspension ".
It is further preferred that the upper jet thrust that several jets are directed downward is additionally provided with along transmission direction in the first drying box 11
14, be equipped with jet thrust 14 on one per 13 top of once jet thrust, nonwoven cloth diaphragm upper jet thrust 14 and lower jet thrust 13 it
Between transmit.The effect of upper jet thrust 14 is to balance lower 13 jet of the jet thrust thrust upward to non-woven fabrics, so that nonwoven
