Needleless electrostatic spinning device

Abstract

The invention discloses a needleless electrostatic spinning device, belongs to the technical field of electrostatic spinning and aims at solving the problems that needle heads are easy to block, the quantity of needle heads is limited, the uniformity is poor and a feeding system is complex in the prior art. The needleless electrostatic spinning device comprises a first rack, an emitting device arranged on the first rack, a solution tank arranged below the emitting device, a second rack, a receiving and transmitting device arranged on the second rack, a high-voltage power supply connected between the emitting device and the receiving device and a collecting device matched with the receiving and transmitting device, wherein the emitting device comprises two planes which do vertically-opposite cyclic motion; the solution tank enables the lower plane of the emitting device to be infiltrated therein; the upper and the lower planes of the receiving and transmitting device are oppositely arranged; the collecting device is used for collecting obtained spinning products. The needleless electrostatic spinning device disclosed by the invention has the advantages of simple structure and good continuity; the problems that the needle heads are easy to block, the quantity of the needle heads is limited, the uniformity is poor and the feeding system is complex are solved.
