Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic spinning, in particular to a cleaning device for an electrostatic spinning nozzle. Background Art

[0002] Electrospinning is a special form of electrostatic atomization of polymer fluids. At this time, the substances split by the atomization are not tiny droplets, but tiny polymer jets that can run for a considerable distance and eventually solidify into fibers. Electrospinning is a special fiber manufacturing process. Polymer solutions or melts are spray-spun in a strong electric field. Under the action of the electric field, the droplets at the needle tip will change from spherical to conical.

[0003] In the spinning process, an electrospinning device is usually recycled. After repeated use, the nozzle holes of the electrospinning nozzles of common electrospinning devices are easily solidified and clogged, so they need to be cleaned regularly. However, the electrospinning nozzles are still in a high temperature state after use, which makes it inconvenient to clean them.

[0004] In view of the deficiencies of the prior art, the utility model provides a cleaning device for an electrostatic spinning nozzle, which solves the problems raised in the background technology. Utility Model Content
