Rotary needleless spinning device

Abstract

The invention belongs to the technical field of electrostatic spinning, and particularly relates to a rotary needleless spinning device which comprises a device body, wherein a hollow disc, a rotatinggear and a solution tank are arranged on the device body, an electrode wire is arranged on the hollow disc, the rotating gear can drive the hollow disc to rotate so as to drive the electrode wire onthe hollow disc to rotate, the solution tank is arranged below the hollow disc, and when the hollow disc rotates, one part of the lower part of the hollow disc is always positioned in the solution tank, so that the electrode wire on the hollow disc can pass through a solution in the solution tank, and part of the liquid is brought out when the electrode wire rotates out of a liquid level. According to the spinning device, the rotary electrode is adopted, manufacturing is convenient, the spinning field intensity of the electrode wire is uniform, and the stability of the physical or chemical property of the spinning solution in the spinning process can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electrostatic spinning, and in particular relates to a rotary needleless spinning device. Background technique [0002] Electrospinning is a special form of electrostatic atomization of polymer fluids. At this time, the substances split by the atomization are not tiny droplets, but tiny jets of polymers, which can run for a long distance and finally solidify into fibers. [0003] Electrospinning technology is a special fiber manufacturing process. The polymer solution or melt is jet-spun in a strong electric field. Under the action of the electric field, the droplet at the needle will change from a spherical shape to a conical shape—that is, a Taylor cone. Fiber filaments are extended from the tip of the cone, which can produce polymer filaments with nanometer diameters. [0004] In recent years, the electrospinning process has received more and more attention in the industry. Because of its extremely fi...

Problems solved by technology

[0005] Aiming at the problems in the above-mentioned prior art that the spinning electrode solution is exposed to the air too much, the physical or chemical properties of the solution are easily changed, and the spinning is unstable, the present invention provides a rotary needleless spinning device. The electrode cover plate greatly reduces the exposed area of ​​the solution, and the space outside the hollow disc is also covered with a cover plate to minimize the direct contact between the solution and the air
