Detailed description of the invention
The electrostatic spinning nozzle of face of cylinder hexagon seven nozzle array as shown in Figure 1 to Figure 3, including body 1, body 1
Having one be positioned at top cylindrical face 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 seven 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 seven connecting holes project end points and this equilateral hexagonal symmetry being respectively at equilateral hexagon in the horizontal plane
In in the heart, namely will constitute the track of equilateral hexagon after six subpoint lines, it is equilateral that last subpoint is positioned at this
Hexagonal center.In embodiment, each group export structure along the axis on the face of cylinder linearly array arrange, and, later group
Export structure is relative to previous group export structure symmetry on the axis direction on the face of cylinder, and adjacent sets export structure shares a company
Connect hole 31 thus this connecting hole 31 is as the symmetrical centre of two groups of export structures.So, all export structures are in the horizontal plane
Projection i.e. constitutes linear array figure, and each unit of this linear array figure is equilateral six limits that centre has symmetrical midpoint
Shape；And it is overlapping that the most adjacent equilateral hexagon shares a subpoint, i.e. this subpoint.It should be noted that
The symmetrical centre of adjacent sets export structure is respectively positioned in the apex lines of the face of cylinder, and namely connecting hole 31 is positioned at face of cylinder apex lines
On.
Thus, electrostatic spinning nozzle i.e. defines the hexagon seven nozzle array structure at face of cylinder axis direction.
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
With this orthohexagonal in the heart, namely six of which connecting hole track on the projection surface constitutes a regular hexagon, another
Individual connecting hole track on the projection surface is orthohexagonal center.This arrangement is more beneficial for ensureing the equal of most advanced and sophisticated electric field
Even.
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
