Description
Technical field
The utility model relates to spinning production technical field, especially a kind of 6 spinning production system of polyamide fibre.
Background technique
For nylon-6 fiber mainly to be sliced based on melt spinning, the PA6 slice (residual moisture content 50PPm) of dry state is continuous
Ground, which enters in screw extruder, to be melted, mixed and is measured.Screw extruder is by the feeding spiro rod in electric heating sleeve, drive
Dynamic motor and reduction gearbox composition.It has steel alloy to be made, and reach after special thermal treatment extreme hardness to meet technique and
The requirement of produce load.Sleeve is heated by electric heating cover, wherein equipped with being accurately controlled and register.Screw extruder
Each area can be individually set to meet the requirement of process conditions.The head pressure of screw extruder is by frequency converter control
The alternating current generator revolving speed of screw extruder processed obtains, and can be appointed under selected head pressure by pressure sensor
Meaning adjusts and keeps screw speed, to adapt to the variation of the condition of production.Existing melt enters molten under the action of head pressure
Body distribution circuit system is furnished with static mixer in melt distribution systems to guarantee that melt has good uniformity.And this is
In application process of uniting, agglomeration traits are easy to appear via the melt that screw extruder squeezes out, so as to cause in melt
TiO2Unevenness is mixed because of reunion, and then the dullness of final products is caused to lose, and influences product quality.
During melt spinning, polymer feeds extruder, send further along after screw rod transmission, plasticizing, melting
Ensure that the melt of polymer can be flowed into stable and uniform critical component spinning group by accurate measurement to metering pump: metering pump
In part, melt passes through the filtering of filter medium in filament spinning component, eliminate after impurity and bubble be provided with by high pressure indentation it is porous
Spinneret in become thread；Thread by horizontal blowing be quickly cooled down (quenching) while, due to following wireline reel effect also
Super drawing is generated, so that diameter attenuates；As-spun fibre is wound into certain package.
Filament spinning component is mainly the filter layer being made of upper layer overcurrent lid, metal mesh and filter sand, distributes under normal conditions
Plate and porous spinneret are constituted.After spinning melt flows into filament spinning component from top-level entries, lie prone type via the back taper minister in ancient times in sand chamber
Overcurrent lid diffusely enter in the inner cavity of component, filtration combination layer is ingeniously entered under the action of upper stressor layer.Filter layer usually has
Multiple filtration net and METALLIC FILTRATION SAND composition.The a piece of coarse net for not luring steel wire to weave into often is placed in the top layer of filter layer, is become
Cover net or cover net, it is therefore an objective to stop the sundries of bulk and prevent the layer of sand of lower part mobile.When being filtered using filter sand, press in principle
Grit size is carefully sequentially arranged by thick.When placing multistorey strainer mesh, and the principle descending by mesh size.In filtering group
The bottom for closing layer has placed one layer of supporting network, it is usually to be made of a piece of or two panels coarse net, it is therefore an objective to support upper layer mistake
Filtering layer increases longitudinal rigidity, has the function that not to be depressed, it can also prevent the work for draining to spinneret orifice under broken filter sand sometimes
With.Melt after fine filtering flows into the hole of distribution plate.On the one hand the effect of distribution plate is to play support upper level filter
Layer, is on the other hand before polymer melt is assigned to spinneret plate as homogeneously as possible, so that the uniform flow in every hole, is also replaced
Spinneret has shared the melt pressure of part, so that spinning plate surface is unlikely to superpressure and deforms.Polymer melt is squeezed into
After the guide hole of spinneret, micropore gives the certain shape of melt and is extruded as strand, finishes to dazzle body like this in spinning group
The design of the filament spinning component of part internal flow need to mainly determine its structure snd size.
