Abstract

The present invention discloses an array multi-nozzle electrospinning device, including an electrospinning liquid supply apparatus, an electrospinning liquid spinning apparatus, a receiving electrode plate, an electrospun fiber transport apparatus and a high voltage electrostatic generator, the electrospinning liquid spinning apparatus includes effusers and nozzles, the nozzles are array-arranged; the electrospun fiber transport apparatus includes a feed roller apparatus and a discharge roller apparatus disposed on two ends of the receiving electrode plate respectively; the electrospun fiber receiving material is transported to the space between the electrospinning liquid spinning apparatus and the receiving electrode plate by the feed roller apparatus, and the discharge roller apparatus transports the received electrospun fiber out; the invention provided device can produce electrospun fiber membrane in large scale, and can produce both single polymer electrospun fiber membrane and multiple polymers blended layered electrospun fiber membrane for one time, and can obtain a electrospun fiber membrane with specific topological pattern by changing electrospun fiber receiving material conveniently, which satisfies various application requirements of electrospun fiber materials.

Description

technical field [0001] The invention relates to an electrostatic spinning device, in particular to an array multi-nozzle electrostatic spinning device. Background technique [0002] Electrospinning has gradually become a simple and effective technique for preparing nano / micro fibers since it was invented by Formhals in 1930. It can successfully prepare most polymers and their copolymers, block copolymers, derivatives, etc. into electrospun fibers ranging from 3 nanometers to 5 microns. The principle is: under the action of a high-voltage electrostatic generator, a high-voltage electrostatic field is formed between the electrospinning liquid spinning device and the electrospinning fiber receiving device, and the polymer solution forms droplets at the nozzle and is charged, and the charged droplets are in the electric field. Under the action of force, it is accelerated at the top of the Taylor cone. When the electric field force is large enough, the charged droplets overcome ...
