Between driving belt 2032, wherein rotating centrifugal column 201 drives transmission by the driving belt 2032 driven by motor 2031.
During work, spinning solution is entered in the cavity of the rotating centrifugal column 201 in rotation status, and is flowed in rotation
In 202 inner cavity of fiber discharge barrel for turning state, under the action of the centrifugal force, the spinning solution of liquid passes through 202 appearance of fiber discharge barrel
Discharge hole 205 on face is thrown away, and during the spinning solution of liquid is thrown away again, can be shaped to the nanofiber 206 of threadiness,
In 206 forming process of nanofiber in this programme, due to be subject to top flabellum 204 orientation apply wind-force act on
And under temperature constant state, the fiberizing speed of its entire fiber of nanofiber 206 is faster and its fibrousness is more elongated
Even, fibre fineness is uniform, and fiber can be determined drop down onto region set by lower section, while its falling speed is also faster, production effect
Rate is with regard to that can be improved, and and then, the nanofiber produced, which falls, to be arrived in the yarn rotating circular disk 301 in rotation status
In chamber, nanofiber in 301 inner cavity of yarn rotating circular disk its yarn rotating circular disk 301 in rotation status rotation
It transfers under use, more nanofiber aggregations wind and twist, and are drawn close from the center of yarn rotating circular disk 301 and gradually form yarn
305 and pass through the inner cavity of 301 hollow-core construction of yarn rotating circular disk on yarn tube 304, so as to produce with Nanowire
Tie up the entire preliminary forming process of yarn.
The examples of implementation of the above are only the preferred embodiments of the invention, and the implementation model of the present invention is not limited with this
It encloses, therefore the variation that all shape, principles according to the present invention are made, it should all cover within the scope of the present invention.
