Detailed description of the invention
The electrostatic spinning nozzle of face of cylinder equilateral hexagon array as shown in Figure 1 to Figure 3, including body 1, body 1 has
Having the face of cylinder being positioned at top and be provided with at least two group export structures, described export structure is for collecting and jet spinning
Liquid.
Often group export structure is by six connecting holes being opened on the face of cylinder and the pin type being connected on connecting hole
Nozzle 2 forms, and the connecting hole in accompanying drawing overlaps with needle nozzle 2, and therefore connecting hole does not the most indicate.Such as Fig. 3
Shown in, these six connecting holes project on the end points being respectively at equilateral hexagon, namely by subpoint line in the horizontal plane
The track of rear composition equilateral hexagon.In this described equilateral hexagon, the line of relative two of which end points is parallel to cylinder
The axis in face, is positioned on the top line on the face of cylinder for the two of which connecting hole in this export structure, and four additional connecting hole is with circle
The top line of cylinder is the both sides that axis of symmetry lays respectively at face of cylinder top line.
In embodiment, each group export structure along the axis on the face of cylinder linearly array arrange, later group export structure phase
For previous group export structure axial symmetry being spaced a distance on the axis direction on the face of cylinder, thus, all export structures
Projection in the horizontal plane i.e. constitutes the linear array figure of the equilateral hexagon at multiple interval.Specifically, with reference to Fig. 3,
The most adjacent above-mentioned equilateral hexagon is zhou duicheng tuxing, and its axis of symmetry is perpendicular to the axis on the face of cylinder, and axis of symmetry is also simultaneously
It is respectively parallel to the limit 31,32 of two equilateral hexagon.Article two, spacing d on limit 31,32 is the spacing of adjacent sets output mechanism.
Above-mentioned needle nozzle 2 is needle point structure away from the end of connecting hole, and this kind of needle nozzle 2 is commonly used in the art
Nozzle structure, is not explained in detail at this.The needle nozzle 2 often organizing export structure is all contour, and different group output
Each needle nozzle 2 of structure is also contour, namely all of needle nozzle 2 is both with respect to contour for the face of cylinder.These pins
Formula nozzle 2 extends along the normal direction on the face of cylinder.
Above-mentioned body 1 can be complete cylindrical structure thus its surface is the face of cylinder, it is also possible to be only one
Part has the structure on the face of cylinder.
Have above-mentioned connecting hole, the electrostatic spinning nozzle of needle nozzle track can greatly reduce in each needle nozzle electric field
Influence each other so that the most advanced and sophisticated electric field of each needle nozzle is more uniform.
Preferably, in same group of export structure, the projection in the horizontal plane of each connecting hole is respectively at orthohexagonal end points
On, namely the track that six connecting holes are on the projection surface constitutes a regular hexagon.This arrangement is more beneficial for ensureing point
Hold the uniform of electric field.
It is furthermore preferred that the spacing of adjacent sets export structure (the most above-mentioned spacing d) is equal with the orthohexagonal length of side, this
Arrangement is more beneficial for ensureing the uniform of most advanced and sophisticated electric field.
The electrospinning process of above-described embodiment is as follows:
As shown in Figure 4, being evenly applied on each needle nozzle 2 by outside coating unit by spinning liquid, body 1 is relative to receipts
Acquisition means 4 is fixed, and needle nozzle 2 is towards collection device 4, and spinning liquid is in needle nozzle 2, collection device 4 institute
Producing induced jet under the induction electric field formed, induced jet is induced to collection device 4 and forms fiber.
In other embodiments of electrostatic spinning nozzle, what needle nozzle 2 can have hollow goes out sap cavity, and this goes out sap cavity and passes through
Before and after logical needle nozzle 2, having inlet on body 1 surface, body 1 is internal has solution channel, goes out sap cavity by correspondence
Connecting hole, solution channel connection inlet.Now, connecting hole may be considered a spray orifice.
The electrospinning process using the preferred embodiment is as follows:
As shown in Figure 4, body 1 is fixed relative to collection device 4, and needle nozzle 2 is towards collection device 4, will
Spinning liquid injects in sap cavity by solution channel and arrives needle nozzle 2 top, and spinning liquid is at needle nozzle 2, collection device 4
Producing induced jet under the induction electric field formed, induced jet is induced to collection device 4 and forms fiber.This spinning process
Can continue with spun structure and carry out spinning incessantly.
Below by way of Electric Field Simulation the electrostatic spinning nozzle in embodiment and the most linearly array arranged with
