Problems solved by technology

The disadvantage of this electrospinning device 2 is that the fiber is limited by the distance between the two ground conductors 22. If the distance between the two ground conductors is too far, the traction force generated will become smaller, and it will not be possible to smoothly generate a scaffold of electrospun fibers to be wound on the two ground conductors. 22, making it difficult to collect tubular fibrous scaffolds

Abstract

An electrospinning device includes a collector unit, a driving unit and a spinning material supplier. The collector unit includes a guide disc and at least one collector bar, the guide disc defines a setting circular arc by taking the axis of the guide disc as the center, and the collector bar and the setting circular arc support the guide disc tangently. The driving unit provides power to the collector unit to enable the guide disc to rotate by the axis, and the collector bar rotates around the own long axis. The spinning material supplier and the collector unit have the high voltage difference, when the spinning material supplier emits the electrospinning towards the collector bar by the action of a high voltage electric field, the electrospinning fibers are arranged parallelly along the long axis or are arranged crosswise into the rhomboids to be wound and collected, and further a tabular fiber support is made.

Description

technical field [0001] The invention relates to a mechanical device for making man-made fibers, in particular to an electrospinning device. Background technique [0002] The diameter of electrospun fibers prepared by electrospinning technology can reach nanometer level, and has the advantages of high porosity, high surface area ratio, high moisture permeability, etc., so it is very suitable for biomedical products; for example, combined with biocompatible material, and coiling at the collection end makes the collected electrospun fibers in a tubular shape, which can be used to make a tubular fiber scaffold, which can then be used as an artificial blood vessel. In addition, based on recent research on cell culture, tissue engineering and vascular reconstruction in patients with cardiovascular diseases, in order to make the fibrous scaffold conducive to cell attachment, migration and proliferation, when the electrospun fibers are arranged and deposited along the tube axis The...
