Background technology
The characteristics such as simple, with low cost and pure physics stretching that electrostatic spinning possesses skills, the following main flow manufacturing technology that very likely becomes nanofiber.Traditional electrostatic spinning efficient is extremely low, and the commercial Application and the commercialization that have seriously restricted nanofiber are promoted.
Along with the maturation of electrostatic spinning technique and going deep into of nanofiber application study, for low this bottleneck of productive rate, the scientific research personnel has carried out a large amount of correlative studys both at home and abroad, and has made some progress.
Chinese patent CN200720076954.6 discloses a kind of high-performance multineedle electrostatic spinning jet device, this device is the natural expansion to traditional single spraying head, yet through long-term experiment, find that the design of Multi needle spray silk exists that spinning head stops up, electric field influences each other between the spinning head, institute's making alive is higher, spinning quality is poor and need to be to problems such as force (forcing) pumps.Nigeria researcher (O.O.Dosunmu, G.G.Chase, W.Kataphinan, D.H.Reneker.Electrospinning of polymer nanofibres from multiple jets on a porous tubular surface.Nanotechnology2006,17:1123-1127) by antipriming pipe nozzle batch electrospinning, utilize the polymer solution of pneumatic shuttle in will managing slowly outside the extrusion cavities, under the effect of high voltage electric field, produce beam jet be ejected into peripheral around the cylindrical reception of layer of metal online.The method needs air pump to assist feed flow, and structure is comparatively complicated, and has the easy blockage problem of pore.(the Theron A such as Yarin, Zussman E, Yarin A L.Electrostatic field – assisted alignment of electrospun nanofibres.Nanotechnology, 2001,12 (3): 384-390.) the Israel researcher proposes a kind of Dualayer solution system that will contain ferromagnetic fluid and places the in batches technology of electrospinning of magnetic field and electric field realization, although this technology can solve the syringe needle blockage problem, but in polymer solution, sneak into easily impurity, affect fiber quality, but also there are Dualayer solution system operation inconvenience, the problems such as fibre diameter lack of homogeneity.In addition, the ELMARCO company of Czech designs a kind of commercial electrostatic spinning machine Nanospider, this device adopts metal roller to replace traditional needle point shower nozzle, during electrospinning metallic cylinder is immersed in the polymer solution, rotation under the driving of motor causes disturbance to the Free Surface of solution, produces jet, the final nanofiber that obtains, but there is the not shortcoming such as easy to clean of residue in it.
Summary of the invention
The purpose of this invention is to provide a kind ofly overcome that feed flow is discontinuous, the jet size difference is large and surface solution such as solidifies at the shortcoming, can guarantee the continuous fiber manufacturing installation of fibre diameter uniformity and continuous electro-spinning nanofiber.
The present invention is provided with motor, connector, turning cylinder, induces roller, pinpoint array, annular reservoir, DC high-voltage power supply, collecting board and liquid feed device;
Motor output shaft is connected with turning cylinder through connector, induce roller and turning cylinder to be rotationally connected, induce roller surface to be provided with gear ring, pinpoint array is installed on induces roller surface, is provided with annular rack in the annular reservoir, annular rack and described gear ring engagement of inducing roller, DC high-voltage power supply is anodal to be connected with annular solution tank, and the DC high-voltage power supply negative pole is connected with collecting board, and collecting board is located at annular solution tank top, collecting board ground connection, liquid feed device is communicated with annular reservoir by woven hose.
Described motor preferably adopts stepper motor.
Described motor output shaft preferably is positioned on the center line of annular reservoir centre bore, and described turning cylinder preferably is horizontal and is vertical with motor output shaft.
The described roller of inducing preferably is rotationally connected by bearing and turning cylinder, and described gear ring preferably is located at and is induced the roller middle part.
Described pinpoint array is installed on induces roller surface, and preferably each needle point of pinpoint array induces the screwed hole of roller surface to be spirally connected with being located at.
Described pinpoint array can be provided with 4 row's needle points, and all along inducing roller shaft to setting, the interval angle of adjacent 2 row's needle points on same circumference is 90 degree to 4 row's needle points.
Operation principle of the present invention and beneficial effect are as follows:
When device is started working, opening high pressure power supply and adjust to certain voltage (such as 50kV) at first, then starter motor, turning cylinder begins to rotate, and turning cylinder drives induces roller to do circumferential movement; Since induce roller cog with annular reservoir in annular rack engagement, make and induce roller to carry out rotation around the axis of turning cylinder, induce the array needle point on the roller to provoke the polymer solution liquid level this moment, assisted solution overcomes the capillary constraint of free surface, produce taylor cone and under electric field action, form a large amount of jets, moving and the solvent evaporates through the unstability whip is finally at collecting board deposition solid nano fiber.After jet sustained firing a period of time of solution surface, will disappear, for this reason before it disappears, the array needle point will again move to this place or near bring out and produce next jet, so go round and begin again, but the continuous electro-spinning nanofiber.Because described roller and the needle point of inducing is small-sized, the distance of needle point and collecting board is little with liquid level and collecting board spacing difference, and a small amount of formed fiber of jet is basic identical with the fibre diameter of liquid level generation on the array needle point so; Induce simultaneously roller inducing the formation jet process less to the electric field interference, guaranteed the uniformity of fibre diameter.In addition, liquid feed device for annular solution tank provides solution, remains unchanged the liquid level of solution in the annular solution tank by woven hose, has realized the continous-stable manufacturing of fiber.
