Description
Technical Field
The utility model relates to an electrostatic spinning collector.
Background
Electrostatic spinning is an attractive superfine fiber processing technology, and a polymer or other spinnable solution is prepared into a fiber with a nanometer diameter by a high-voltage electric field. Compared with other nanofiber processing methods, the electrostatic spinning method is easy to obtain fibers with the diameter of dozens of nanometers to hundreds of nanometers, and the range of processable materials is wide, and the fibers comprise polymers, mixtures, semiconductors, metals or ceramics and the like; when the solution is sufficiently supplied, continuous and uniform nano-fibers can be obtained; the receiving method is flexible, and fiber materials with different structures can be obtained. The electrostatic spinning nanofiber shows unique physical, chemical, electrical, magnetic, optical, thermal and other properties due to the influence of surface effect, volume effect and quantum size effect, and has good application prospect in the fields of electronics, energy, environment, biology, medical treatment, chemical industry and the like. The earliest electrospinning collectors were primarily received using simple flat plates and the resulting product was a thin film of micron nanofibers with randomly arranged fibers, and thus it was only suitable for nonwoven-like felt materials. In some applications, however, the required electrospun material is in the shape of a circular tube. For example, in the medical field, the connector of nerve fiber is made of nanofiber-based tubular material, and the nanofiber-based tubular material can be used as an intestinal stent of animals and can be made into a degradable intestinal stent. The nano-fiber tubular material can also be applied to the fields of water pollution and the like, and plays a role in filtration. Therefore, the nanofiber-based tubular material has very wide application. However, the existing nanofiber-based tubular material is tightly attached to the receiving roller, is not easy to separate, and is easy to damage when the nanofiber-based tubular material is taken down.
SUMMERY OF THE UTILITY MODEL

With the increase of the spinning time, the thickness of the nanofiber-based tubular material prepared by electrostatic spinning is increased. After electrostatic spinning is finished, the rubber block and the metal block are taken down firstly, the nanofiber-based tubular material is separated from the end portion of the receiving roller along with the circular sleeve extending the clamping groove, the nanofiber-based tubular material is taken down, and due to the fact that the support is lost, the arc-shaped inserts are separated from each other in the center of the nanofiber-based tubular material, and then the nanofiber-based tubular material falls off, so that the nanofiber-based tubular material prepared through electrostatic spinning is obtained. Therefore, the arc-shaped plug-in can enable the nano-fiber tubular material attached to the surface of the arc-shaped plug-in to be taken down and easy to fall off; and the plurality of arc-shaped plug-ins can be freely installed after demoulding; the rubber block can prevent relative slippage between the arc-shaped plug-in unit and the receiving roller, and the metal blocks arranged at the two ends of the arc-shaped plug-in unit can keep conduction of the whole device in a state of connecting the anode and the cathode.
