Description

Technical Field

[0001] The utility model relates to the technical field of melt spinning injectors, in particular to an automatic calibration mechanism of a melt spinning injector. Background Art

[0002] Melt electrospinning technology is an effective method for manufacturing polymer micro-nano fibers. Its principle is to manufacture nanofibers by stretching the polymer melt through a strong electric field to form a jet stream deposition. Under the action of the strong electric field, the adhesion material at the melt spinning needle changes from a sphere to a cone (Taylor cone), and extends from the tip of the cone to obtain fiber filaments. In order to obtain good fiber filaments, it is necessary to heat the needle. There are many existing heating methods, including laser heating. Laser heating has excellent performance and is accepted by the public.
