Embodiment Construction

[0024] Such as Figure 1 to Figure 3 The illustrated electrospinning nozzle with an annular array of cylindrical surfaces includes a body 1 having a cylindrical surface and three sets of output structures, and the output structures are used for collecting and spraying spinning solution.

[0025] Each output structure is composed of a plurality of connecting holes opened on the cylindrical surface and needle nozzles 2 respectively connected to the connecting holes. The connecting hole in the figure coincides with the needle nozzle 2, so the connecting hole is not marked. The said connecting holes are all on a straight line segment, that is, after connecting the connecting holes, the line is a straight line track, and the straight line segment is parallel to the axis of the cylindrical surface. The straight line segments formed in each group of output structures are image 3 The straight line segments in trajectories 3, 4, and 5. reference figure 2 with image 3 , The output str...

Abstract

The invention discloses an electrostatic spinning sprayer of a cylindrical surface annular array and an electrostatic spinning method. The sprayer comprises a body, the body is provided with a cylindrical surface and three output structures. Each output structure comprises a plurality of connection holes in the cylindrical surface and needle type nozzles connected to the connection holes. The connection holes of each output structure are located on the same linear section. The output structures are distributed in an array in the circumferential direction of the cylindrical surface, so that the three linear sections are in parallel, and the needle type nozzles extend in the normal direction of the cylindrical surface and are equal in height. The three output structures are distributed in the array in the circumferential direction of the cylindrical surface, the three connection holes and the needle type nozzles in the corresponding positions of each output structure are also distributed in the array in the circumferential direction, compared with the prior art that nozzles are distributed on the plane in a linear array track, electric field intensity difference of the nozzles in the distribution mode is small, and tip electric fields of the nozzles are more uniform. The sprayer and the method can be used for electrostatic spinning.

Description

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