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] Such as figure 1 with figure 2 The electrospinning nozzle of the trapezoidal wave array shown includes a nozzle main body 3, and the nozzle main 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 three sets of output structures are provided on the nozzle main body 3, and the output structures are used to collect and spray the spinning solution 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. The end of the needle nozzle 4 away from the spray hole is a needle tip, and this needle nozzle 4 is a commonly used nozzle structure in the...

Abstract

The invention discloses a trapezoidal wave array electrospinning nozzle and an electrospinning device, comprising a nozzle body, the nozzle body has an output plane and at least three sets of output structures, and each set of output structures includes The four nozzle holes on the top and the needle nozzles respectively connected to the nozzle holes, the four nozzle holes of each group of output structures are respectively located on the vertices of a trapezoid, and the latter group of output structures is symmetrical to the center of the previous group of output structures. Adjacent groups of output structures share one nozzle hole so that the nozzle hole serves as the center of symmetry of the two groups of output structures, and the needle nozzles are of the same height. Compared with the prior art in which the nozzles are arranged in a linear array track, the present invention has less mutual electric field influence among the nozzles, smaller difference in the electric field intensity of each nozzle, and larger electric field intensity of each nozzle. The present invention can be applied to electrospinning.

Description

technical field [0001] The invention relates to the field of electrospinning, in particular to an electrospinning nozzle and an electrospinning device of a trapezoidal wave array. 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 problems...
