Problems solved by technology

If you need to make a tube, you can only curl the flat non-woven fabric into a cylindrical shape, and then use adhesive to bond the joints. This process is cumbersome, and the use of adhesive may introduce foreign materials.
[0004] Most of the above-mentioned electrospinning devices are of principle and self-assembled in the laboratory, and there is no adjustable and controllable complete set of equipment that can meet various research and production needs

Abstract

The invention relates to static spinning machine, which comprises: a high-voltage system, a material supplier, an ejection height adjuster, and a collector, wherein said power system is formed by high-voltage direct-current static generator, an anode and a cathode; the supplier is formed by a cup support, a micro ejection pump, and an ejector; the adjuster comprises a group of worm systems integrated with the liquid storage cup, while one end of it fixes the liquid storage cup and another end has the worm wheel meshed with worm, to slide along the trapeze groove at the side edge of worm groove; and the collector can be metallic plate shape, mesh shape and tube shape.

Description

technical field [0001] The invention relates to an electrospinning instrument, in particular to an electrospinning instrument with a rotatable cylindrical collector, a flat or grid-shaped collector, which belongs to the field of textile machinery, and is especially suitable for spinning various nanoscale fibers. Background technique [0002] Electrospinning is a process that uses a polymer solution or melt to form a jet flow under the action of a strong electric field for spinning. In the process of electrospinning, the injection device is filled with charged polymer solution or molten liquid. Under the action of an external electric field, the polymer droplets held at the nozzle by the surface tension will accumulate charges on the surface under the induction of the electric field. , is subjected to an electric field force in the opposite direction to the surface tension. When the electric field is gradually strengthened, the droplet at the nozzle is elongated from a sphe...
