The electrospinning liquid impregnating mechanism comprises a raw material tank and a sizing drum, wherein the raw material tank is used for placing an electrospinning liquid, and the sizing rolling drum rotates in the raw material tank. The chain-like emitting electrode is in contact with the sizing rolling drum, so as to enable the electrospinning liquid to be attached onto the chain-like emitting electrode. The high-tension electricity generator is respectively electrically connected with the chain-like emitting electrode and the receiving electrode.

Description

technical field [0001] The present invention relates to an electrospinning device, and in particular to a drum-type electrospinning device. Background technique [0002] Electrospinning technology is one of the manufacturing technologies that can produce nanofibers (Nanofibers). Its principle is mainly to use the electric field driving force between the positive and negative electrodes to overcome the surface tension and viscosity of the electrospinning solution of the polymer, so that the electrospinning solution forms fine fibers. fiber. In the prior art, a high voltage is applied to the polymer electrospinning solution by the emitter electrode. After the charged electrospinning solution is sprayed through the nozzle (Spinneret), it repels each other due to the same charge, and disperses into filaments. The shaped electrospinning solution is drawn to the collector by the attraction between the positive and negative electrodes. After the solvent in the electrospinning sol...

Problems solved by technology

However, in the existing electrospinning technology, most of the charged electrospinning solution is injected into the negative electrode receiver through the nozzle. Because the aperture of the nozzle is extremely small, after many times of use, the nozzle or pipeline will often be blocked by residues.

And when changing different types of electrospinning solutions, it is necessary to cooperate with cleaning pipelines and nozzles, thus reducing the scope of use of electrospinning solutions

[0004] China Taiwan Patent No. TW200827501 proposes an electrospinning device, which uses a drum-type feeding mechanism and is equipped with a linear emitter electrode to solve the problem of nozzle clogging

However, the initial voltage required by the wire-shaped emitting electrode is high, and it is difficult to achieve the effect of uniform electrospinning due to its large width.
