Electrostatic spinning device with auxiliary air flow and equipment

The invention discloses an electrostatic spinning device with auxiliary air flow and equipment thereof. A receiving electrode is positioned above a liquid storage tank; a rotary spinning roller is arranged in the liquid storage tank; an electrostatic spinning region is formed between a region where the receiving electrode is orthographically projected to the spinning roller and the receiving electrode; a plurality of through holes are uniformly formed in the spinning roller; an air spraying structure which is kept static is arranged in the spinning roller; an air spraying region of the air spraying structure corresponds to the electrostatic spinning region; the air spraying structure upwards sprays air flow; the air flow is blown into the electrostatic spinning region through the through holes. Under the matching between air flow blowing force and electrostatic force, electrostatic spinning is implemented; compared with the conventional roller type spinning, the electrostatic spinning device disclosed by the invention has the advantages that the yield is increased from 5 times to 10 times, and the spinning efficiency is greatly improved; furthermore, by the adoption of a liquid suction nozzle structure and a scraper structure, a spinning solution in the liquid storage tank is positioned in a sealed environment; therefore concentration change caused by volatilization of a solvent is avoided, and pollution caused by the volatilization of the spinning solution is prevented.
