Abstract

The invention provides a production line of an electrostatic spinning nanofiber membrane. The production line comprises a base fabric unwinding device, a vertical and horizontal tension regulating device, an electrostatic spinning box body, a drying device, a protective layer base fabric unwinding device and a winding device, wherein the base fabric unwinding device is used for unwinding non-wovenbase fabric and conveying the unwound non-woven base fabric to the electrostatic spinning box body, even unfolding of base fabric in the vertical and horizontal direction in a working area of the electrostatic spinning box body is ensured through the vertical and horizontal tension regulating device so as to collect the produced nanofiber membrane on the base fabric, and protective layer base fabric is covered on the surface of the nanofiber membrane through the protective layer base fabric unwinding device; and the drying device is used for evaporating residual solvents in the nanofiber membrane covered by the protective layer base fabric and shaping the nanofiber membrane, and the winding device is used for winding the dried nanofiber membrane. The system has a simple structure and convenient operation, and wide-width electrostatic spinning nanofiber membrane can be produced effectively, continuously and stably, so that industrial preparation of the electrostatic spinning nanofiberis achieved.

Description

Technical field [0001] The invention relates to the technical field of electrospinning equipment, in particular to a wide continuous production line for electrospinning nanofiber membranes. Background technique [0002] Electrospinning is a special form of the electrostatic atomization of polymer fluids. At this time, the substance split by atomization is not tiny droplets, but tiny polymer jets, which can run for a long distance and finally solidify into fibers. Electrospinning is a special fiber manufacturing process in which polymer solutions or melts are jet-spinned in a strong electric field. Under the action of an electric field, the droplet at the needle will change from a spherical shape to a conical shape (that is, a "Taylor cone"), and extend from the tip of the cone to obtain fiber filaments. In this way, polymer filaments with nanometer diameter can be produced. [0003] The Chinese invention patent with application number 201310032194.9 discloses an umbrella-shaped e...
