The present invention relates to a nanofiber manufacturing apparatus which comprises: a nozzle block comprising a nozzle plate which has sheath/core-type multitubular nozzles arranged thereon, at least two spinning solution storage plates which are placed under the nozzle plate and supply a spinning solution to the multitubular nozzles, overflow removal nozzles which surround the multitubular nozzles, and the multitubular nozzles which are connected to the overflow removal nozzles and discharge a polymer solution; a collector arranged above the nozzle block and collecting fibers spun from the nozzle block; and a power supply unit applying a high voltage between the nozzle block and the collector. The tip portions of the nozzles connected to the nozzle block are formed into a shape of a divergent tube. The present invention relates to the nanofiber manufacturing apparatus in which the tip portions of the nozzles connected to one part of the nozzle block are arranged in a form of a divergent tube so a density difference and a voltage difference are not generated. Furthermore, the present invention has an advantage of allowing the mass production of nanofibers which have a uniform quality. |
