Technical Field

[0002] The preparation process of nanofiber membranes usually involves electrospinning, a technology that uses electrostatic forces generated by high-voltage electric fields to prepare nanoscale fibers.

[0003] When manufacturing nanofiber membranes, the solution is sprayed into filaments through electrospinning technology and then attached to non-woven fabrics, forming a fiber web or film on the non-woven fabrics.

[0004] Nanofiber membranes prepared by electrospinning technology have many advantages, such as large specific surface area, high porosity, excellent mechanical properties, etc. This makes nanofiber membranes have broad application prospects in filtration, separation, sensing, energy and biomedicine.

[0005] After the non-woven fabric is sprayed with a solution of charged polymer by an electrostatic spinning machine, it needs to be transported to a drying device for drying. The dried non-woven fabric is then rolled up by a rolling device.

[0038] Both ends of the collecting roller 421 are provided with connecting ends 423. The connecting end 423 at one end of the collecting roller 421 is provided with a through hole connected to the water absorption chamber.

The dried base fabric is then rolled up on the base fabric winding device 6 through the base fabric winding traction device 5.

[0046] The driving motor 49 is started. When the base fabric passes through the drying device 4, the driving motor 49 can drive the extrusion roller 411 to rotate. The rotation speed of the extrusion roller 411 is the same as the rotation speed of the roller on the drying device 4.
