The invention discloses a nanofiber electrostatic spinning device which comprises a base. A working chamber is arranged on the base and internally provided with a spinning nozzle device, a receiving plate, an electrode plate and a material taking scraper. The receiving plate is rotated through a rotating supporting device. The nanofiber electrostatic spinning device is simple in structure and reasonable in design; the electrode plate and the receiving plate which are separated are used for replacing an existing powered receiving conveying belt, and the electrode plate and the receiving plate are separated, so safety is higher; meanwhile, by circularly receiving nanofiber through the receiving plate and collecting the nanofiber through the material taking scraper, the collecting effect is high, the effect is good, and maintaining and cleaning are more convenient.
