Abstract

The invention discloses a differential electrostatic spinning solution sprayer. The differential electrostatic spinning solution sprayer mainly comprises a sprayer sleeve, a sprayer spindle, a bearing, a tooth-shaped belt and a motor, wherein the lower part of the sprayer spindle is a cone body, a plurality of small division troughs are uniformly formed in the outer surface of the cone body, a hollow space is formed in the cone body, a 60-degree angle is formed between the outer surface of the cone body and the horizontal line, a 30-degree angle is formed between the inner surface and the horizontal line, the edge of the cone body is formed into a point, the sprayer spindle is matched with the sprayer sleeve in a sealing mode through the bearing, the sprayer spindle is rotatable, the position of the sprayer spindle can be regulated in the vertical direction, the upper end of the sprayer spindle is connected with the motor through the tooth-shaped belt, and the sprayer spindle is driven to rotate through the motor. The differential electrostatic spinning solution sprayer uses the differential principle, and the solution is divided through the division troughs in the surface of the sprayer; the sprayer spindle is rotatable, the problem of low output of single solution spray needle is solved, and the uniformity of the Taylor cone is guaranteed; the differential electrostatic spinning solution sprayer greatly improves the electrostatic spinning efficiency and lays a certain foundation for the industrialization of solution electrostatic spinning.

Description

technical field [0001] The invention relates to an electrostatic spinning device, which belongs to the field of electrostatic spinning. Background technique [0002] With the heating up of nanotechnology, the preparation of nanofibers by electrospinning has become one of the current research hotspots. Since the invention of electrospinning technology, after nearly a hundred years of development, great progress has been made in spinning methods and spinning materials. However, for solution electrospinning, the defect of low yield has always restricted it. process of industrialization. Therefore, considering how to increase production, it is inevitable to put electrospun nanofiber related products on the market. Many industrialized devices of solution electrospinning equipment simply expand the number of spinning needles, but this method still cannot avoid the problems of difficult processing, easy clogging and mutual interference of electric fields in spinning needles, such...
