ELECTROSPINNING DEVICE FOR MANUFACTURING NANOFIBER

The present invention relates to an electrospinning device for manufacturing a nanofiber, and the purpose of the present invention is to provide an electrospinning device for manufacturing a nanofiber, wherein a substrate is transferred while a nanofiber web is stacked and formed on a side surface of the substrate through electrospinning of a polymer spinning solution, and the substrate is rotated during transfer such that the nanofiber web is stacked and formed on the other side surface; accordingly, the nanofiber web can be stacked and formed on both surfaces of the substrate through a single manufacturing process; a drying process is performed simultaneously during rotation of the substrate such that, at the same time the nanofiber web is stacked on both surfaces of the substrate, the substrate is dried through a single manufacturing process, thereby removing any solvent remaining on the nanofiber web; and, as electrospinning devices, electro-blown electrospinning devices and electro-spinning electrospinning devices are installed alternately, such that electro-spinning electrospinning and electro-blown electrospinning can be performed alternately with regard to a transferred substrate.
