Description
Technical field
The present invention relates to nanofiber production field, the supply especially with regard to a kind of nano fiber electrostatic spinning machine is coated
Mechanism.
Background technology
Electrostatic spinning was a simple and convenient, cheap and environmentally safe spining technology, early in 30 years 20th century
In generation, foreign countries just report in its patent utilizes high-voltage electrostatic spinning, the feed flow dress of existing nanofiber producing device
Put and mostly polymer solution is sprayed by the spout of syringe needle shape, and then reach the purpose of supply polymer solution, more first
The commercial plant of the nanofiber producing device entered be then by coating unit, by polymer solution coating with electrostatic spinning,
The purpose of polymer solution is reached, but the coating method of existing nanofiber is generally linear reciprocation coating method, this painting
The mode of covering makes the two ends of electrostatic spinning occur in that two kinds of extreme cases, and one is repetitive coatings in short-term, two when being long without coating, this two
The order of severity of the situation of kind is gradually reduced with the two ends of electrostatic spinning to the centre of electrostatic spinning, and both of these case is in certain journey
The operating efficiency of electrostatic spinning is have impact on degree, the yield of nanofiber is reduced.
The content of the invention
Polymer solution repetitive coatings and length in short-term that the two ends of the electrostatic spinning existed for above-mentioned nanofiber occur
When the situation without coating, the present invention propose a kind of supply coating mechanism of nano fiber electrostatic spinning machine, this mechanism can be effective
The above-mentioned problem of solution.
To solve above technical problem, the technical scheme that the present invention is provided is:
A kind of supply coating mechanism of nano fiber electrostatic spinning machine, including：Rotary electric machine, coating unit, electrostatic spinning,
Measuring pump, High voltage power supply equipment and feed pipe, one end of the coating unit are fixedly connected with rotary electric machine, are stayed on coating unit
There is coating groove, inlet is left in the coating groove upper end, and the inlet is communicated with coating groove；One end of the measuring pump and confession
Liquid pipe is connected, and one end is connected with inlet, and the electrostatic spinning is connected with High voltage power supply equipment, and electrostatic spinning is in annular point
In cloth, the electrostatic spinning insertion coating groove of annular, the center of circle for the annular that electrostatic spinning is in is located at coating unit with rotating
On the vertical line of the fixed position of motor, when the rotary electric machine is rotated, coating unit is driven to do circulatory motion, while measuring pump is logical
Cross feed pipe and obtain polymer solution, then by inlet, polymer solution, the annular rotation of coating unit are supplied to coating groove
The motion of coating groove is driven, so that polymer solution is coated on electrostatic spinning；
Further, the electrostatic spinning is 3-5 bars, preferably 3, the number of slots amount and coating groove of the coating groove
The quantity of the measuring pump of upper end is identical with the quantity of electrostatic spinning；
Further, the reasonable spacing between the electrostatic spinning of close two is 35cm-40cm；
Further, the spacing between close two coating grooves is 35-40cm；
Further, the quantity delivered of the polymer solution of the measuring pump, lateral rotary electric machine consolidates outside coating unit
Positioning, which is put, gradually successively decreases.
Beneficial effects of the present invention are：
The present invention is reasonable in design, simple in construction, and the electrostatic spinning for effectively solving common nanofiber occurs in short-term
Repetitive coatings and it is long when without coating the problem of, when being coated operation to polymer solution, make polymer solution in Static Spinning
Coating on silk is more well-balanced, not only saved the use of polymer solvent, improves polymer solvent in electrostatic spinning
Service efficiency, while improving the yield of nanofiber.
