Problems solved by technology

[0003] However, after a long period of use, technicians found that when the nozzles are arranged in a rectangular array, the electric fields at the tips of the nozzles will affect and interfere with each other, making the difference in the electric fields between different nozzles large and resulting in uneven spinning; even the electric field of some nozzles Not enough to reach the critical spinning value

Embodiment Construction

[0018] like figure 1 and figure 2 The illustrated electrospinning nozzle in a trapezoidal periodic array includes a nozzle body 3 , and the nozzle body 3 has a liquid outlet channel inside for introducing external spinning liquid. In addition, the nozzle main body 3 has an output plane and at least two sets of output structures are provided on the nozzle main body 3, and the output structures are used to collect and spray the spinning liquid entering from the outlet channel for spinning.

[0019] In the embodiment, each group of output structures includes four nozzle holes opened on the output plane and needle nozzles 4 respectively connected to the nozzle holes. As shown in the drawings, the nozzle holes are not labeled, but those skilled in the art It is easy to understand that the spray hole and the needle nozzle 4 overlap. These needle spray groups 4 are all metal nozzles with needle points at the ends away from the spray holes. This needle nozzle 4 is a commonly used s...

Abstract

An electrospinning device using a trapezoidal periodic array electrospinning head includes a solution tank, a conduit connected to the outlet of the solution tank and an electrospinning head, wherein the electrospinning nozzle comprises a spray nozzle main body; the spray nozzle main body has an output plane and at least two sets of output structures; each group of output structures includes four spraying holes arranged in the output plane and needle nozzles respectively connected to the spraying holes; the four spraying holes of each group of output structures are located in vertexes of a trapezoid respectively. Each group of output structures is arranged in a linear array so that the lines connecting all the adjacent spraying holes constitute a trapezoidal trajectory and all the needle nozzles are equal in heights. Compared with the prior art, the electrospinning device are provided with the nozzles which are arranged in the linear array trajectory, so that mutual electric field effects among the nozzles are quite small; the intensity differences of electric field of all nozzles are small; and the intensity of the electric field of all nozzles is quite high. The electrospinning device can be applied to electrospinning.

Description

technical field [0001] The invention relates to the field of electrospinning, in particular to an electrospinning device using a trapezoidal periodic array of electrospinning nozzles. 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 a rectangular array, the electric fields at the tips of the nozzles will affect and interfere with each other, making the difference in the electric fields between different nozzles large and resulting in uneven spinning; even the electric field of some nozzles Not enough to reach the critical spinning value. Contents of the invention [0004] In order to solve the above prob...
