Abstract

The invention provides an electrostatic spinning device, comprising a material barrel, a piston which is arranged in the material barrel and is capable of being moved in the material barrel, a spinning nozzle which is arranged at one end of the material barrel and is communicated with the material barrel, a high-voltage power supply device which is connected on the spinning nozzle, a receiving board which is arranged correspondingly to the spinning nozzle in position, and a grounding power supply wire for grounding the receiving board. The electrostatic spinning device further comprises a sealed spinning area surrounding the spinning nozzle and the receiving board; and a magnetic field generating device forming a parallel magnetic field is arranged in a fiber receiving area in the sealed spinning area. According to the electrostatic spinning device provided by the invention, the influence of external airflow on the stability of jet flow can be prevented by arranging the sealed spinning area; and the magnetic field generating device is additionally arranged in the fiber receiving area of the sealed spinning area, and nanometer fibers are acted by the parallel magnetic field when passing through a magnetic field, so that the parallel and order nanometer fibers are collected on the receiving board. The electrostatic spinning device provided by the invention has the advantages of being simple in structure, convenient in operation, simple in control and short in process flow.

Description

technical field [0001] The invention relates to an electrostatic spinning device, in particular to an electrostatic spinning device capable of anti-interference spinning ordered fibers. Background technique [0002] Electrospinning is a special form of electrostatic atomization of polymer fluids. At this time, the substances split by atomization are not tiny droplets, but tiny jets of polymers, which can run for a long distance and finally solidify into fibers. Compared with electrospinning, electrostatic atomization uses different working media. Electrostatic atomization uses low-viscosity Newtonian fluid, while electrospinning uses high-viscosity non-Newtonian fluid. Correspondingly, the in-depth study of electrostatic atomization technology also provides a certain theoretical basis and knowledge base for the electrospinning system. The term "electrospinning" comes from "electrospinning" or earlier "electrostatic spinning", which is generally referred to as "electrospinni...
