Receiving device for bilaterally collecting electric spinning polymer fiber tubes

Abstract

The invention discloses a receiving device for bilaterally collecting electric spinning polymer fiber tubes and aims at providing the device for preparing a porous fiber tubular material which is composed of two types of polymer fiber and has the even wall thickness on the radial direction and the axial direction. The bilateral receiving device comprises a receiving frame system which is independent of a host box body, a controllable regulation system for rotation speed of a metal rod, a rotating disc-connecting rod system which drives the metal rod to do the gradient non-uniform motion on the horizontal direction and a controllable pause system of the host box body arranged at two ends of a track. Wherein, the receiving frame system can realize the bilateral simultaneous collection of fiber; the controllable regulation system for the rotation speed of the metal rod can realize the adjustable speed of the received metal rod by over-regulation of the rotation speed of a speed control motor; the rotating disc-connecting rod system can realize the gradient non-uniform motion of a host on the horizontal direction; and the controllable pause system of the host box body arranged at two ends of the track can realize the controllable pause of the host box body at two ends of the track. The receiving device is applicable to preparing tissue engineering blood vessel stents and other porous fiber tubular materials.

Description

technical field [0001] The invention relates to a device for collecting electrospun polymer fiber tubes, in particular to a receiving device for collecting different electrospun polymer fiber tubes from both sides by receiving the rotation and translation of a metal rod. Background technique [0002] In the electrospinning process, the polymer solution at the capillary mouth is stretched into polymer fibers with diameters ranging from micrometers to nanometers under the action of tens of thousands of volts of high-voltage electrostatics, and sprayed to a zero-potential receiving device. The solvent evaporates quickly, and when the receiving device is a grounded metal rod, the fibers are deposited on its rotating surface and removed to obtain a tubular polymer material. Currently, it is possible to collect an electrospun polymer fiber into a tube from the receiving metal rod side. The existing device is equipped with parallel metal rods at the front end of the host box, whic...

Problems solved by technology

The defect of the existing device technology is: because the fiber ejection point is fixed, and the metal rod moves at a uniform speed in the horizontal direction, the obtained tube is in the shape of thin ends and thick middle; the fiber ejection point is located directly in front of the middle point of the track, so There are fewer fibers sprayed at both ends of the phase track, and the original device returns immediately when the metal rod moves to the two ends of the track, which cannot provide sufficient time to collect fibers, resulting in the phenomenon that the middle of the tube wall
