Abstract

The invention discloses a multi-needle-head spinning fiber preparation device and method based on an online algorithm. A high-pressure liquid delivering device is arranged to drive a spinning solutionto flow to a gap between a solid needle head and a nozzle groove, an electric field is formed between the solid needle head and a rotating spherical shell through a direct-current high-pressure generator, under drainage of the solid needle head, the spinning solution can form a Taylor cone liquid bag at the needle point of the solid needle head, under stretching of the electric field effect, thespinning solution at the needle point of the solid needle head is used for spraying spinning fibers and is deposited on the surface of the rotating spherical shell, the rotating spherical shell rotates at a high speed, so that the spinning fibers are regularly distributed under the action of mechanical force, the diameter of the fibers is smaller, and the orientation degree of the spinning fibersis improved. The multiple spraying grooves and the corresponding solid needle head are arranged, meanwhile, the high-pressure liquid delivering device is used for driving the flow speed of the spinning solution to accelerate spinning, and thus, the spinning efficiency is higher.

Description

technical field [0001] The present application relates to the technical field of electrospinning equipment, in particular to a multi-needle spinning fiber preparation device and method based on an online algorithm. Background technique [0002] Electrospinning is currently one of the simplest and most efficient methods for preparing polymer nanofibers. It has attracted widespread attention at home and abroad for its advantages such as simple equipment, wide range of raw material sources, and low cost. [0003] The electrospinning device is mainly divided into three parts: a high-voltage DC power supply, a spinneret and a target electrode. The function of the DC high-voltage power supply is to provide high voltage to form a strong electric field between the spinneret and the target electrode, so as to carry out the charged polymer. For high-strength drawing, the spinneret is connected to the positive pole of the high-voltage power supply to generate fine jets, and the target ...
