Description

technical field [0001] The invention relates to a nanofiber electrostatic spinning device Background technique [0002] Electrospinning, as the most novel and convenient technology for forming micron and nanofibers, has been paid more and more attention. However, most of the electrospinning equipment currently adopts the method of single nozzle, multiple nozzles, rotating nozzles or composite nozzles. However, regardless of the method of single nozzle, multiple nozzles, rotating nozzles or composite nozzles, due to the small diameter of the nozzles, there are problems such as difficult cleaning and high production capacity. Especially for the method of multiple nozzles, the electric field interference between adjacent nozzles cannot be effective. Avoiding, affecting the uniformity of the mass-produced fibers, the quality and efficiency of the produced fibers need to be improved, and cannot meet the requirements of product applications. Contents of the invention [0003] I...
