Abstract

The invention provides an electrostatic spinning device and a cleaning method of an electrostatic spinning nozzle of the electrostatic spinning device. The electrostatic spinning device comprises an injector pushing mechanism, an injector, the electrostatic spinning nozzle, a control system, a movement platform and a collector, wherein the injector is arranged on the movement platform, the injector pushing mechanism is arranged at one end of the injector, the electrostatic spinning nozzle is arranged at the other end of the injector, a high-voltage direct-current power supply is connected with the electrostatic spinning nozzle, the high-voltage direct-current power supply and the movement platform are connected with the control system, and the collector is arranged on the movement platform; the electrostatic spinning nozzle comprises an upper nozzle portion and a lower nozzle portion which are connected with the injector, the upper nozzle portion is of a hollow structure, the side wall of the upper nozzle portion is provided with a through hole, the lower nozzle portion is in a solid cone shape, solution in the injector oozes out through the through hole, the solution flows to the tail end of the nozzle along the Taylor cone to form a Taylor cone and jet flow, and the jet flow is collected on the collector and deposits to form fibers. The electrostatic spinning device and the cleaning method can resolve the problem of blocking of the nozzle, and thinner fibers can be spun. The cleaning method of the nozzle is easy and convenient to implement.

Description

technical field [0001] The invention relates to an electrostatic spinning device and a method for cleaning an electrostatic spinning nozzle thereof, and belongs to an innovative technology of an electrostatic spinning device and a cleaning method for an electrostatic spinning nozzle thereof. Background technique [0002] Electrospinning technology Electrospinning technology was first proposed by Formhzls in 1934, and then Taylor et al. proposed the concept of Taylor cone for the deformation of charged polymers in the electrospinning process in 1964. It was not until the 1990s that people began to Extensive attention has been paid to electrospinning technology. However, nanofibers produced by electrospinning are difficult to collect in an orderly manner, and it is also difficult to arrange them in an orderly manner. [0003] At present, the preparation of nearly a hundred different polymer nanofibers, various types of polymers, inorganic composite nanofibers and inorganic na...
