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.

Melt differential electrospinning device and process

A tire direct-pressure shaping and electromagnetic induction heating curing method uses an inner metal mold including large and small segments, a telescoping mechanism, supporting plates attached to the segments, and induction heating coils. A cavity in the middle of the segments is filled of phase change material. The temperature of the mold rises rapidly by the thermal effect of an eddy current generated on the surface of the segments to heat the green tire. When the middle part of the segment is heated to a certain temperature, the phase change material absorbs and stores the excess heat. Therefore, the temperature of the middle part of the segment differs from one of two ends of the segment. Once the tire is cured, the inner mold in the expanded condition and the outer mold support very high pressure for the green tire together.
