Description

technical field [0001] The invention relates to a flow-controlled reciprocating rotary melt electrospinning machine, which belongs to the field of electrospinning and the field of machinery. Background technique [0002] Melt electrospinning is a method of preparing micro-nano fibers by using the drawing effect of electrostatic force on molten polymer jet. Since melt electrospinning does not use solvents and does not require high conductivity of polymers, spinning costs and environmental pollution are also greatly reduced, and there are many types of polymers suitable for melt electrospinning. However, traditional melt electrospinning, the obtained fibers are difficult to reach the nanoscale under the combined action of gravity and electric field force. Using the upward melt electrospinning technique with the collecting plate above the spinneret, the electric field force and gravity can fully stretch the polymer jet to obtain nanoscale fibers. [0003] In the traditional e...
