Problems solved by technology

[0003] However, after a long period of use, technicians found that when the nozzles are arranged in an array on a plane, the electric fields at the tips of the nozzles will affect and interfere with each other, making the difference in the electric field between different nozzles large and resulting in uneven spinning

Embodiment Construction

[0027] Such as Figure 1 to Figure 3 The electrospinning nozzle of the cylindrical triangular axisymmetric array shown includes a body 1, the body 1 has a cylindrical surface at the top and is provided with at least two sets of output structures, and the output structures are used to collect and spray spinning solution .

[0028] Each set of output structure is composed of three connecting holes on the cylindrical surface and needle nozzles 2 respectively connected to the connecting holes. The connecting holes in the drawings coincide with the needle nozzles 2, so the connecting holes are in figure 1 and figure 2 Not marked in . The connecting lines of these three connecting holes form a triangular trajectory, that is, the three connecting holes are on the endpoints of a triangle, and the connecting line segments of two connecting holes are parallel to the axis of the cylindrical surface. In other words, by this One of the sides of the triangle formed by the three connecti...

Abstract

The invention discloses a cylindrical surface triangular axisymmetric array static spinning nozzle and static spinning method. The static spinning nozzle includes a nozzle body which is provided with a cylindrical surface at the top and at least two groups of output structures, the output structures are arranged in a linear array along the axial direction of the cylindrical surface, the next output structure is in axial symmetry in the axial direction of the cylindrical surface with respect to the previous output structure and the output structures are spaced from each other at a distance, each output structure includes three connecting holes that are arranged in the cylindrical surface, each connecting hole is connected with a needle-type nozzle, the needle-type nozzles extend along the normal direction of the cylindrical surface and are at the same height, the line connection of the connecting holes in the same one output structure forms a triangular locus, and the line connection section of two of the connecting holes is parallel to the axis of the cylindrical surface. The needle-type nozzles are small in electric field intensity, and the tip electric field of each nozzle is more uniform. The static spinning nozzle can be applied to static spinning.

Description

technical field [0001] The invention relates to the field of electrospinning, in particular to an electrospinning nozzle and an electrospinning method with a rhombus spaced array on a cylindrical surface. Background technique [0002] The invention patent with the application number 200910031948.2 discloses an array multi-nozzle electrospinning equipment, which uses multiple nozzles arranged in a linear rectangular array on the plane for spinning, which can realize mass production of electrospun fiber membrane materials. [0003] However, after a long period of use, technicians found that when the nozzles are arranged in an array on a plane, the electric fields at the tips of the nozzles will affect and interfere with each other, resulting in large differences in the electric fields between different nozzles, resulting in uneven spinning. Contents of the invention [0004] In order to solve the above problems, the object of the present invention is to provide an electrospi...
