Centrifugal electrostatic spinning device

Abstract

The invention relates to the technical field of electrostatic spinning, in particular to a centrifugal electrostatic spinning device which comprises an outer shell, a spinning sprayer, a spinning receiver and a power supply device. A spinning space for containing the spinning sprayer and the spinning receiver is formed in the outer shell, the spinning receiver is connected at the negative high-voltage end of the power supply device and comprises a plurality of spinning collecting rods, fabric unwinding reels and fabric winding reels, the spinning collecting rods are circularly arranged aroundthe spinning sprayer, each fabric unwinding reel is positioned on the first side of each spinning collecting rod, each fabric winding reel is positioned on the second side of each spinning collectingrod, and fabrics wound on the fabric unwinding reels bypass the collecting rods and are connected with the fabric winding reels after the collecting rods are tightened. According to the centrifugal electrostatic spinning device, the spinning receiver is provided with the spinning collecting rods, the fabric unwinding reels and the fabric winding reels, the fabric unwinding reels are matched with the fabric winding reels, spinning yarns on the spinning collecting rods are continuously collected, and spinning is continuously implemented, so that spinning efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electrostatic spinning, in particular to a centrifugal electrostatic spinning device. Background technique [0002] Polymer nanofibers and their composites have the advantages of excellent high porosity, high specific surface area, and good ductility. In recent years, nanofibers have been widely used in textile materials, tissue engineering scaffolds, drug delivery, filter media, artificial blood vessels, Biochips, nanosensors, optics, composite materials and other fields. At present, the preparation technology of polymer micro-nano fibers mainly includes template polymerization method, phase separation method, self-assembly method, and spinning processing method. Among them, spinning processing method includes melt blown method, electrospinning method, centrifugal spinning method, Two-component composite spinning method, etc. The traditional electrospinning method can be divided into melt electrospinni...

AI Technical Summary

Problems solved by technology

The diameter of the nozzle is too large and the speed of the nozzle is too low to make the diameter of the spinning fiber thicker, and the distribution of the nanofibers evolved from the spinning jet on the receiving device is not uniform, and the uniformity of the nanofiber film is not good; in addition, the spinning A fixed ring collector is used for silk collection, and the spinning film on the collector needs to be removed frequently, which cannot achieve continuous spinning collection, which limits the efficiency of spinning collection
