Problems solved by technology

At present, the electrospinning device used for industrial production usually arranges multiple groups of nozzles side by side, and the nozzles are parallel to each other, but the electric fields formed between the nozzles interfere with each other, and the electric field lines are not distributed along the length of the nozzles. The ejected spinning will be subject to component forces in other directions, which will affect the quality of the final product

Embodiment Construction

[0027] The core of the present invention is to provide an electrostatic spinning nozzle, which makes the electric field more uniform and improves the jetting quality of spinning.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the electrospinning nozzle of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Such as figure 1 As shown, it is a front view of a specific structure of the electrospinning nozzle of the present invention, figure 2 for the side view, image 3 For top view. The electrospinning nozzle includes a body 1 and a spray needle 2. The spray needle 2 is fixedly installed on the body 1 and connected to the solution channel in the body 1. The spinning solution flows through the solution channel, and the spinning solution is guided by the electric field force. Spray outwards through the spray needles 2; ...

Abstract

The invention discloses an electrostatic spinning nozzle which comprises a body and at least two rows of nozzle needles. The nozzle needles are connected to the body and communicated with a solution channel inside the body. The nozzle needles are distributed in rows in the length direction of the body. An included angle is formed between the two adjacent nozzle needles. Voltage is applied to the nozzle needles during spinning, electric fields are generated at the nozzle needles, the electric fields affect each other, the two nozzle needles are kept in parallel, distribution of the electric fields is not uniform, the spinning effect is affected, the certain included angle is formed between the two adjacent rows of nozzle needles, the distribution of the structure can offset the component of an electric field perpendicular to the nozzle needles, the electric field force borne by spinning jetting is consistent with the extending direction of the nozzle needles, the distribution of an electric field at the tips of the nozzle needles is uniform, and therefore the spinning quality is improved.

Description

technical field [0001] The invention relates to the technical field of electrospinning, and further relates to an electrospinning nozzle. Background technique [0002] Electrospinning is a special form of electrostatic atomization of polymer fluid. Electrospinning uses non-Newtonian fluid with high viscosity. Under the action of high-voltage electrostatic generator, a high-voltage electrostatic field is formed between the spinning device and the receiving device. The polymer solution forms droplets at the nozzle and is charged. The charged droplets are accelerated at the top of the Taylor cone under the action of the electric field force. When the electric field force is large enough, the charged droplets overcome the surface tension to form a charged jet, which can run for a long time. When the charged jet runs in the electrospinning space, it is accompanied by solvent volatilization, bending and stretching, and is finally collected by the receiving device and solidified to...
