A self-rotating electrospinning device assisted by high-pressure airflow

Abstract

The invention discloses an automatic-rotating electrostatic spinning device assisted by high-pressure airflow and provided with a nozzle and belongs to the field of electrostatic spinning. The automatic-rotating electrostatic spinning device mainly comprises a feeding device, an air compressor, the spinning nozzle, an electrode plate, a high-voltage electrostatic generator, a spread net belt, a hot roll and an air pumping system. The spinning nozzle is composed of a flow adjustment valve, a spinning nozzle body, a rotary body, a solution spinning rotating nozzle, a nozzle air cap and a feeding flow passage. With the high-pressure airflow principle of melt spinning and a centrifugal electrospinning device integrated, the automatic-rotating electrostatic spinning device solves the problem that a solution electrospinning single-spraying needle is low in efficiency and overcomes the defects that the diameter of fibers is too large and die head processing difficulty is large in the melt-blowing spinning method. The automatic-rotating electrostatic spinning device is designed in a detachable mode, can be maintained by replacing the nozzle, and is wide in application range and low in maintenance cost.
