Description of drawings
Describe electrostatic spinning apparatus provided by the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the gathering-device schematic diagram of existing electrostatic spinning apparatus.
Fig. 2 is the structural representation of this novel wound form electrostatic spinning apparatus.
The specific embodiment
Below, twining silk device with numerical control nanometer shown in Figure 2 spinning is that example illustrates electrostatic spinning apparatus provided by the utility model.
The spinning of numerical control nanometer twines silk device and comprises fuselage 1, two groups of spinning appts 2 and one group of gathering-device 3, and printing opacity protective cover 6.Two groups of spinning appts 2 are separately positioned on the left and right sides of the base of fuselage 1.Printing opacity protective cover 6 covers spinning appts 2 and gathering-device 3, and is fixed on the base 10, provides protection and handled easily to spinning appts 2 and gathering-device 3.
Spinning appts 2 comprises feeding tube 21, vertical nut 22 and spinning head 23.Two groups of spinning appts lay respectively at the left and right sides of fuselage, and comprise at least one spinning head 23 respectively.Printing opacity protective cover 6 is fixed on the top of feeding tube 21, and feeding tube 21 is connected by vertical nut 22 and is fixed on the fuselage 1.About the end in opposite directions of feeding tube 21 of two groups of spinning appts 2 connect spinning head 23 respectively.The spinning head 23 of two groups of spinning appts is provided with in opposite directions, connect opposite polarity high pressure respectively, promptly connect positive and negative high voltage source respectively, form the required electric field of electrospinning silk therebetween, the silk stream of the oppositely charged of spinning head 23 ejection is aloft attracted each other, is collided, charge neutrality, becomes the nanofiber that flying speed reduces rapidly.Utilize vertical nut 22, the feeding tube 21 of the left and right sides can be finely tuned along the vertical direction.Correspondingly, spinning head 23 is also regulated by vertical nut 22, move up and down with respect to fuselage, thus the influence of control solvent evaporates and fiber itself gravity to collecting.
Have the line slideway 4 and the displacement control motor 5 that are symmetricly set on the base 10 on the fuselage 1.Utilize line slideway 4 and displacement control motor 5, can adjust two distances between the spinning head 23, promptly, under the control of displacement control motor, spray silk system in left side can be within the specific limits moves to left end along line slideway 4, and right side spray silk system can be within the specific limits moves to right-hand member along line slideway 4.As shown in Figure 2, left side spray silk system is by the displacement control Electric Machine Control in left side, left side spray silk system can be moved to left end within the specific limits, and right side spray silk system can move right side spray silk system by the displacement control Electric Machine Control on right side within the specific limits to right-hand member.
Gathering-device 3 is positioned at the below apart from mid point of spinning head 23, comprises twining a motor 31, spurs handle 32, twines fiber tube 33, arranges silk motion pipe 34 and torsion wire motion turntable 35 compositions.Wherein torsion wire motion turntable 35 links to each other with the base 10 of fuselage 1, and fuselage 1 relatively, rotates on horizontal plane round the axle perpendicular to fuselage 1.Row's silk motion pipe 34 is connected on the torsion wire motion turntable 35.Twine fiber tube 33 by twining on a motor 31 and pulling handle 32 rows of the being fixed on silk motion pipe 34.Torsion wire motion turntable 35 control row silk motion pipes 34 move in a circle on horizontal plane.34 controls of row's silk motion pipe twine fiber tube 33 move left and right in the horizontal direction.Twine a motor 31 controls and twine fiber tube 33 on direction, carry out drum movement around the axle that is parallel to base 10 perpendicular to fuselage 1.Therefore, carry out rotatablely moving of horizontal plane, and then drive and twine fiber tube 33 and rotate at horizontal plane because torsion wire motion turntable 35 drives row's silk motion pipe 34; And, because 34 controls of row silk motion pipe twine fiber tube 33 move left and right on horizontal plane, on horizontal plane, be rotated motion simultaneously and move horizontally so twine fiber tube 33, can make be collected in the fiber thickness that twines on the fiber tube 33 evenly and also fiber produce distortion character.
When carrying out electrospinning, polyester (PET) done section is dissolved in trifluoroacetic acid and carrene mixes in the solution of composition by a certain percentage, at room temperature stir and make the certain density electrospinning silk uniform solution for the treatment of.With the solution that configures after static several minutes, be added in the injector of electrostatic spinning apparatus and carry out electrostatic spinning.
Because two spinning heads 23 connect positive and negative high voltage source respectively, formed the required electric field of electrospinning silk therebetween, so the filament that ejects respectively from two spinning heads 23 has opposite polarity electric charge.Filametntary silk stream is aloft attracted each other, is collided, charge neutrality, two spinning heads 23 apart from mid point near form the nanofiber that flying speed reduces rapidly, on the surface that twines fiber tube 33.
As described above, twining fiber tube 33 moves horizontally simultaneously on horizontal plane and rotatablely moves.This can make the even and generation distortion attached to the fiber thickness that twines fiber tube 33 surfaces.In addition, twine fiber tube 33 under the effect that twines a motor 31, also center on rotatablely moving of horizontal rotational shaft simultaneously.Thus,, can in layer be wound on the surface that twines fiber tube 33, just can realize that the bar cartridge type of electro spinning nano fiber is collected, and then can carry out back processing efficiently electro spinning nano fiber attached to the fiber that twines fiber tube 33 surfaces.
Utilize vertical nut 22, the feeding tube 21 and the spinning head 23 of the left and right sides all can be finely tuned along the vertical direction, thereby by adjusting spinning head 23 apart from the distance of mid point to the upper surface 331 that twines fiber tube 33, with control spinning distance.
As described above, utilize line slideway 4 and displacement control motor 5, can adjust two horizontal ranges between the spinning head 23.
Gathering-device in the utility model comprises the torsion wire motion turntable that is positioned on the fuselage, be positioned at the row's silk motion pipe on the torsion wire motion turntable, and be positioned at the fiber tube of arranging on the motion pipe that twines, and torsion wire motion turntable rotates with respect to standard of fuselage, and the row's of drive silk moves to manage and also horizontally rotates; The row's silk motion management and control system that horizontally rotates twines fiber tube and moves horizontally when horizontally rotating.Twine fiber tube and under the control that twines a motor 31, also center on rotatablely moving of trunnion axis.Therefore, this electrostatic spinning apparatus makes receiving system be independent of spinning appts, and the fiber tube 33 that twines in the receiving system does not need ground connection or connects negative voltage, can be metallic conductor, also insulating materials.
The utility model adopts the coiling gathering-device, can realize that the bar cartridge type of electro spinning nano fiber is collected, and then can carry out back processing efficiently to electro spinning nano fiber, utilizes macroscopic conditions to realize arranging efficiently, assemble and spin.Therefore, this electrostatic spinning apparatus adapts to the large-scale industrialization production of electro spinning nano fiber.
