A device and method for removing electrospinning liquid beads with a stopper

Abstract

The invention discloses a baffle block-arranging cleaning device and method of static spinning dope beads. The cleaning device comprises an injector arranged above a motion platform, wherein the top of the injector is provided with an injector pushing mechanism used for pushing down the solution inside the injector, and the motion platform is in contact with the ground; the lower portion of the injector is electrically connected with a high-voltage power source, and a high-voltage electric field is formed through the lower portion of the injector and the motion platform; a baffle block is arranged between the motion platform and the injector, and horizontally positioned just below the injector, and a thread seam, one end of which is open, is formed in the baffle block to enable spinning to pass through; a brush is arranged at the end, the opening of which is made outward, of a thread seam, and the other end of the baffle block is connected with a first pushing mechanism, and driven through the first pushing mechanism to move to the brush horizontally; the brush is driven through a second pushing mechanism to reciprocate toward the thread seam horizontally, and two sensors used for detecting dope bead flow are arranged on the baffle block symmetrically about the thread seam in a face-to-face mode; the sensors are electrically connected with the second pushing mechanism. Compared with the prior art, the technical scheme has the advantages of being safer, more reliable and good in stability.

Description

technical field [0001] The invention relates to the technical field of electrospinning, in particular to an electrospinning bead removal device and method with a stopper. Background technique [0002] In 1934, Formalas invented the experimental device for preparing polymer fibers by electrostatic force and applied for a patent. The patent announced how the polymer solution forms a jet between the electrodes. This is the first patent describing in detail the use of high-voltage static electricity to prepare fiber devices. It is recognized as the beginning of the preparation of fibers by electrospinning technology. [0003] From the 1930s to the 1980s, the development of electrospinning technology was relatively slow. Most of the scientific research and technical personnel concentrated on the research of electrospinning devices, and issued a series of patents, but none of them attracted widespread attention. In the 1990s, the Reneker research group at the University of Akron ...
