Abstract
A melt differential electrospinning device and process, the melt differential electrospinning device comprising a spinning nozzle (), a fiber receiving device (), a first high-voltage electrostatic generator (), a second high-voltage electrostatic generator (), a grounding electrode (), and n layers of electrode plates of a first electrode plate () and a second electrode plate (), n being an integer greater than or equal to 2; the spinning nozzle comprises a splitter plate (), a nut (), a spring spacer (), an air pipe positioning pin (), a screw (), a nozzle body positioning pin (), a nozzle body (), an air pipe (), a heating device (), a temperature sensor () and an inner cone nozzle (). The melt differential electrospinning process employs the melt differential electrospinning device, such that the polymer melt, under the effect of a wind field and an electric field, is uniformly distributed into a circle of dozens of Taylor cones along the conical surface end, and is further formed into dozens of jet flows and refined into nanofibers; and a plurality of melt differential electrospinning nozzles are installed below the splitter plate, thus realizing large-scale production of nanofibers, with a simple structure, and easy machining and assembly of components.
