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 rectangular five-nozzle array shown includes a body 1, the body 1 has a cylindrical surface at the top and 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 five 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 with figure 2 Not marked in . Such as image 3 As shown in , the projections of these five connection holes on the horizontal plane are respectively located at the endpoints of the rectangle and the symmetrical center of the rectangle, that is, the locus of the rectangle is formed by connecting four of the projection points, and the last projection point is located at the center of the rectangl...

Abstract

The invention discloses a cylindrical surface rectangular five-jet array static spinning nozzle and a static spinning method; the static spinning nozzle comprises a body; the body is provided with a cylindrical surface on the top and at least two output structures; the output structures are arranged in a linear array along the axis direction of the cylindrical surface; certain distance is arranged between adjacent output structures; each output structure comprises five connecting holes arranged on the cylindrical surface, wherein each connecting hole is connected with a needle type jet, and all needle type jets extend in a normal direction of the cylindrical surface and are equal in height; projections of all connecting holes of the same output structure on a horizontal plane are respectively located on end points of the rectangle and the center of the rectangle; two adjacent rectangles are axisymmetric graphs, wherein the symmetric axis is parallel to the edges of the rectangle. The needle type jets are small in electric field intensity differences, and tip electric fields of the jets are more even; the static spinning nozzle and the static spinning method are applied to static spinning.

Description

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