Embodiment Construction
[0026] Such as Figure 1 to Figure 3 The illustrated electrostatic spinning nozzle with a triangular linear array of cylindrical surfaces includes a body 1 having a cylindrical surface at the top and at least two sets of output structures. The output structures are used for collecting and spraying spinning solution.
[0027] Each output structure consists of three connecting holes opened on the cylindrical surface and needle nozzles 2 respectively connected to the connecting holes. The connecting holes in the figure coincide with the needle nozzles 2, so the connecting holes are in figure 1 with figure 2 Not marked in. The three connecting holes are respectively located on the three end points of an isosceles triangle, that is, the line of the three connecting holes constitutes an isosceles triangle track. The end point of the vertex angle of the isosceles triangle is located on the top line of the cylindrical surface, that is, one of the connecting holes is located on the top l...

The invention discloses a cylindrical surface triangular linear arrayed electrostatic spinning spray head and an electrostatic spinning method. The cylindrical surface triangular linear 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 spaced by a certain distance and are distributed in the axis direction of the cylindrical surface in a linear array mode. Each output structure set comprises three 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 the three connection holes in the same output structure set are located on end points of an isosceles triangle. The end points of apex angles of the isosceles triangles are located on the top line of the cylindrical surface, and the bottom side of each isosceles triangle is perpendicular to the axis of the cylindrical surface. 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 triangular linear arrayed electrostatic spinning spray head and the electrostatic spinning 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 cylindrical triangular linear 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, technicians found that when the nozzles are arranged in an array on a plane, 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 electrostatic s...
