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

[0025] Such as Figure 1 to Figure 3 The illustrated electrospinning nozzle in a cylindrical hexagonal array includes a body 1 with a cylindrical surface on the top and at least two sets of output structures for collecting and spraying spinning solution.

[0026] Each set of output structure is composed of six 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 . Such as image 3 As shown, the projections of these six connection holes on the horizontal plane are located at the endpoints of the equilateral hexagon, that is, the trajectory of the equilateral hexagon is formed by connecting the projection points. In the embodiment, each group of output structures is arranged in a linear array along the axis of the cylindrical surface, then the projection of all the output struct...

Abstract

The invention discloses a cylindrical-surface hexagonal-array electrostatic spinning sprayer and an electrostatic spinning method. The cylindrical-surface hexagonal-array electrostatic spinning sprayer comprises a body, wherein the body is provided with a cylindrical surface located at the top and at least two sets of output structures, each set of output structures is arranged in a linear array in the axis direction of the cylindrical surface and comprises six connecting holes formed in the cylindrical surface, projections of all the connecting holes in the same set of output structures on the horizontal plane are located on endpoints of an equilateral hexagon respectively, every two adjacent sets of output structures share two connecting holes, a needle-type nozzle is connected to each connecting hole, and all the needle-type nozzles extend in the normal direction of the cylindrical surface and are equal in height. All the needle-type nozzles have a small electric field intensity difference, and electric fields at the sharp ends of all the nozzles are more uniform. The electrostatic spinning sprayer can be applied to electrostatic spinning.

Description

technical field [0001] The invention relates to the field of electrospinning, in particular to an electrospinning nozzle with a cylindrical hexagonal array and an electrospinning method. 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 electrospinning nozzle with ...
