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 electrospinning nozzle of the cylindrical hexagonal seven-nozzle array shown includes a body 1, the body 1 has a cylindrical surface on the top and is provided with at least two sets of output structures, and the output structures are used for collecting and jet spinning liquid.

[0026] Each set of output structure is composed of seven 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 seven connection holes on the horizontal plane are respectively located on the endpoints of the equilateral hexagon and the symmetrical center of the equilateral hexagon, that is, the six projection points are connected to form an equilateral hexagon. locus, the last projected point is at the cente...

Abstract

The invention discloses a cylindrical surface hexagon seven-nozzle arrayed electrostatic spinning spray head. The cylindrical surface hexagon seven-nozzle arrayed electrostatic spinning spray head comprises a body. The body is provided with a cylindrical surface located on the top and at least two sets of output structures. The output structure sets are distributed in a linear array mode in the axis direction of the cylindrical surface. Each output structure set comprises seven connection holes formed in the cylindrical surface, wherein each connection hole is connected with a needle-type nozzle, the needle-type nozzles extend in the normal direction of the cylindrical surface and are equal in height, and projections, on a horizontal plane, of the connection holes of the same output structure set are located on end points of an equilateral hexagon and a symcenter of the equilateral hexagon. The subsequent output structure set is in symmetry with the previous output structure set in the axis direction of the cylindrical surface, and the adjacent output structures share the same connection hole which serves as a symcenter of the two output structure sets. The electric field intensity difference of the needle-type nozzles is small, and the tip end electric fields of the nozzles are more uniform. The cylindrical surface hexagon seven-nozzle arrayed electrostatic spinning spray head can be used for electrostatic spinning.

Description

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