Abstract

The invention discloses a spray head of a meshy double-cylinder cylindrical electrostatic spinning device. The spray head is composed of a cylindrical spray head body and a cylindrical liquid supply device with a meshy gap; the cylindrical liquid supply device is connected with a solution propeller at the outer side of the cylindrical spray head body through a hose, and a shell of the cylindricalspray head body is connected with a high-pressure generator; the cylindrical liquid supply device is driven by a second electromotor and rotates relative to the cylindrical spray head body; in order to prevent a solution from dripping due to aggregation of the solution, the cylindrical liquid supply device rotates in the cylindrical spray head body, grids on the cylindrical liquid supply device are aligned with a spinning metal roller alternately, liquid drops on the grids are subjected to electrostatic spinning alternately from a gap of the cylindrical spray head body, and the excess liquid is scraped off on the cylindrical spray head body, so that electrostatic spinning can be carried out stably and continuously. The spray head of the meshy double-cylinder cylindrical electrostatic spinning device has the advantages that through the control on the liquid level height in meshy cylinders, the solution pressure is controlled, the charge accumulation is generated on the gap edge on the cylinder surface, and the grids on the cylindrical liquid supply device are aligned with the spinning metal roller alternately to achieve electrostatic spinning of the meshy double cylinders.

Description

technical field [0001] The invention relates to a nozzle of a net-shaped double-tube cylindrical electrostatic spinning device, which belongs to the technical field of electrostatic spinning and textile machinery. Background technique [0002] Electrospinning technology began in the 1930s and is a common method for the direct production of nanofibers. The method has short technological process and simple operation, and its products are mostly used in high-tech fields such as high-efficiency filter materials, biomedical materials, and chemical sensors. [0003] When polymer fiber diameters are reduced from the micrometer scale to the submicrometer or nanometer scale, a surprising set of properties emerges. Such as a very large volume specific surface area, the volume specific surface area of ​​nanofibers is basically 1000 times that of microfibers; it can be flexibly functionalized on the surface; it shows superior effects and mechanical properties compared with other known ...
