Embodiment
With reference to specific embodiment, the invention will be further described.
The present embodiment provides a kind of process units of nano fiber non-woven fabric, the process units bag of the nano fiber non-woven fabric
Fixing bracket 1 is included, it is hollow to further include as hollow rotating centrifugal column 2, the inner cavity being fixedly connected on 2 bottom of rotating centrifugal column
Cylinder fiber type discharge barrel 4, be arranged on fiber discharge barrel 4 and along its circumferencial direction set multiple discharge holes 6, be arranged on
On fiber discharge barrel 4 and along multiple flabellums 5 of its circumferential directions, for drive rotating centrifugal column 2 rotate drive component
300 and for ensureing that the environment temperature in 4 inner cavity of fiber discharge barrel is in the self-constant temperature control assembly 700 of temperature constant state.
Above-mentioned rotating centrifugal column 2 passes through the bearing being provided with and the rotary motion of the composition horizontal direction of fixing bracket 1, flabellum
5 are located at the top of the discharge hole 6, wherein when rotating centrifugal 2 rotary motion of column, multiple fans on fiber discharge barrel 4
Leaf 5 is with 2 synchronous rotary of rotating centrifugal column and the fiber to discharge through 4 top discharge hole 6 of fiber discharge barrel is blown at the same time
Wind, to promote the fiber after discharging to accelerate drawing-off, and enables fiber accurately to orient and spreads on the non-woven fabrics of lower section.This above-mentioned kind
The structure type of flabellum 5 is set, its one side ensure that discharging fiber its during the natural and graceful gauze to bottom under being thrown out of,
It is due to being subject under the wind-force effect of flabellum 5, and the fiberizing speed of its whole fiber is faster and its fibrousness is more elongated
Even, fibre fineness is uniform, and fiber can be determined drop down onto region set by non-woven fabrics, while its falling speed is also faster, production
Efficiency is with regard to that can be improved；Another aspect flabellum 5 is just directly arranged on fiber discharge barrel 4, may be such that whole device need not
Again separately plus extra exhaust apparatus, and this kind of structure type its also make it that whole device structure is compacter, wind-force effect effect
Fruit is more preferable and cost is cheaper.
With reference to shown in referring to the drawings 2, in order to preferably so that being fallen under fiber alignment set by the non-woven fabrics of lower section
On region, above-mentioned flabellum 5 in the present embodiment from set obliquely to its end air inducing portion 51, from air inducing portion 51 to flabellum 5
Air dam 52 that inner side is extended obliquely and by the windshied part 53 that outer ledge side extends downwardly thereon of air dam 52
Form.Air inducing portion 51 is the outer end region for being arranged on flabellum 5, and it acts as driving air to be flowed obliquely along its bottom face
To 52 region of air dam, air dam 52 is arranged on the stub area on flabellum 5, flow to 52 region of air dam air its leading
Under the common operational of wind portion 52 and windshied part 53, air will near vertical flow downward, specifically, flow to wind-guiding
Moving air on 52 bottom face of portion, its under the effect of cross sectional shape that air dam 52 is extended obliquely, moving air its
Can be subject to the downward active force in 52 section of air dam and active force to the left, at the same moving air its can be subject to be located at air dam
The active force of windshied part 53 to the right on 52 outer ledges, therefore, in the case where the flabellum 5 of this kind of structure type acts on, fiber can
Orient set by the non-woven fabrics 9 stably fallen on down below on region.In addition, in order to enable flabellum 5 has during the work time
For more preferable action effect, above-mentioned each flabellum 5 in this programme is in be arranged in obliquely on fiber discharge barrel 4, each flabellum 5
The slanted angle formed with fiber discharge barrel 4 in vertical direction is 25 ° to 45 °.
Above-mentioned self-constant temperature control assembly 700 in this programme is led including what heating plate 701 and heating plate 701 were electrical connected
Electric slip ring 702, conducting slip ring 702 are connected with external power supply, it is used to provide operating current to heating plate 701.
Above-mentioned drive component 300 in this programme includes motor 301 and is connected between rotating centrifugal column 2 and motor 301
Driving belt 302, wherein rotating centrifugal column 2 drives transmission by the driving belt 302 driven by motor 301.
During work, spinning solution is entered in the cavity of the rotating centrifugal column 2 in rotation status, and is flowed in rotation
In 4 inner cavity of fiber discharge barrel of state, under the action of the centrifugal force, the spinning solution of liquid passes through on 4 outer surface of fiber discharge barrel
Discharge hole 6 is thrown away, and during the spinning solution of liquid is thrown away again, it can be configured to the nanofiber 8 of threadiness, in this programme
8 forming process of nanofiber in, its due to be subject to top 5 wind-force of flabellum effect and under temperature constant state, Nanowire
To tie up the fiberizing speed of 8 its whole fiber faster and its fibrousness is more elongated uniform, overall appearance form is good, while under it
Terminal-velocity degree also faster, production efficiency with regard to that can be significantly improved, nanofiber 8 after shaping directly under fall on the non-woven fabrics of lower section
On 9 surfaces.
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
Enclose, therefore the change that all shape, principles according to the present invention are made, it should all cover within the scope of the present invention.
