Rice material rapidly develop and the widely applied epoch, nano material have become push contemporary science and technology progress mainstay it
One.
There is many unique properties and new rule in nano material, such as small-size effect, skin effect, quantum size
Effect, macro quanta tunnel effect etc..Nanofiber is similar with other nano materials, and dimensional effect is very significant, light, heat,
Magnetic, electricity etc. show many new kink characteristics, therefore receive the highest attention of researcher, be expected to be applied to clothes, food,
The fields such as medicine, the energy, electronics, papermaking, aviation.The potential using value of nanofiber provides for the development of its technology of preparing
New development space, while also proposed new requirement.
Currently, a large amount of positive charge is usually had, when spinning is constantly sprayed since the spinning ejected has high voltage
While being mapped to receiver board, receiver board gradually also has accumulated a large amount of positive charge, although receiver board is grounded simultaneously, electrospinning
Largely positively charged receiver board can not be exported silk bring simply by ground connection, and the continuous accumulation of positive charge leads to spinning
Eject position offset, inaccurately, thus eventually lead to spin film different location became uneven one.

Aiming at the problems existing in the prior art, the utility model provides a kind of Static Spinning reception for enhancing stability of spinning process
Device, the reception device can reduce the instability mode that the spinning whip of nanometer spinning end moves, improve the uniformity for spinning film, improve
The quality of Electrospun nano-fibers.
To achieve the above object, the utility model uses following technical scheme:
A kind of Static Spinning reception device enhancing stability of spinning process, the device include syringe needle fixed plate, injection syringe needle, receive
The root of plate and anion generator, the injection syringe needle is fixed in syringe needle fixed plate, the syringe needle fixed plate and receiver board
Between be arranged in parallel, be distributed with electric field between the syringe needle fixed plate and receiver board, the anion generator setting is connecing
Receive the back side of plate, the reception plate earthing.
The receiver board is to receive pole plate, drum-type receiver board or multiple combined receiver board.

Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, the Static Spinning reception device of the present embodiment enhancing stability of spinning process, which includes syringe needle fixed plate
1, syringe needle 2, receiver board 3 and anion generator 4 are sprayed, the root of the injection syringe needle 2 is fixed in syringe needle fixed plate 1, institute
It states and is arranged in parallel between syringe needle fixed plate 1 and receiver board 3, electric field 5 is distributed between the syringe needle fixed plate 1 and receiver board 3,
The back side of receiver board 3 is arranged in the anion generator 4, and the receiver board 3 is grounded.
Preferably, receiver board 3 is to receive pole plate, drum-type receiver board or multiple combined receiver board in the present embodiment.
Preferably, the distance between anion generator 4 and receiver board 3 L are 150-900mm in the present embodiment.
As further preferred, the distance between anion generator 4 and receiver board 3 L are 500- in the present embodiment
600mm。
As further preferred, the working air current pressure of 4 intermediate ion air pressure gun of anion generator is 40- in the present embodiment
100Psi, air velocity 10M/sec.
As still more preferably, negative ion concentration caused by anion generator 4 is 5000- in the present embodiment
15000/cm3。
The present embodiment ejector pin headband high voltage, nearly 300,000 volts, and receiving plate earthing is 0 voltage.Raw material polylactic acid,
With high positive charge after the high voltage processing that polyethylene oxide passes through injection syringe needle, and can be transported to the direction of low potential
It is dynamic, spinning is formed, until contacting receiver board.Since positive charge is assembled near receiver board, keep the jet stream of Electrospun end unstable,
Spinning film becomes uneven thickness.It is added after anion generator through this embodiment, the negative electrical charge that receiver board generates constantly neutralizes
Positive charge on receiver board, neighbouring potential is relatively stable, and receiver board is influenced to weaken significantly by its positive charge, makes spinning more
Stablize.
