Description
Technical field：
The present invention relates to a kind of melt spinning stage cooling devices, belong to synthetic fiber spinning technical field.
Background technology：
Melt spinning method is divided into as polymerization, co-blended spinning method, core-sheath spinning method, is a kind of common spinning side
Method, the melt come out from screw extruder are sent to spinneret assembly by metering pump.The latter is by filter screen, distribution plate and spinneret
Deng composition, effect is the impurity removed in melt, and melt is made equably to send to spinneret.Existing spinneret with it is heat-resisting,
Corrosion resistant stainless steel material is made, and the aperture on face is arranged according to certain rules, and aperture is usually 0.2~0.5 millimeter.Melt is logical
Cross the keyhole formation melt stream on spinneret.Melt stream is cooled and solidified after spraying by the effect of cold air.Thread and
The heat exchange of surrounding medium is mainly carried out with conduction and convection type.The temperature of melt stream gradually declines in cooling procedure,
Viscosity is then continuously improved, and when viscosity is increased to certain critical value and winding tension has been insufficient to allow fiber to continue to attenuate, just reaches
Solidification point.Solidification length refers to length of the melt stream from spinneret aperture to solidification point, this is the key area that fibre structure is formed
Domain.
For the type of cooling of existing thread generally by the way of air-cooled, cooling blowing mode is divided to horizontal blowing and blow-through wind two
Kind.The wind direction of horizontal blowing is vertical with fiber, and straight blowing direction and fibers parallel generally mostly use horizontal blowing.The fibre of different cultivars
Dimension and different fibers is different to cooling requirement, spin polyester and polyamide cord line fiber be then often below spinning head and cold
But setting heating device keeps as-spun fibre structure uniform, tensile property is good to drop low-fiber cooling velocity above room.It is spinning
(such as monofilament) Chang Yishui is coolant when coarse sliver fiber processed, and fiber is made to cool down rapidly.And existing cooling wind is directly horizontal blows
Mode does not adapt to the demand of different fibers.
Invention content：
The purpose of the present invention is providing a kind of melt spinning stage cooling device in view of the above problems, it is convenient for root
According to the cooling temperature of different fiber properties control and cooling position, spinning effect is good, high yield rate.
Above-mentioned purpose is realized by following technical scheme：
Melt spinning stage cooling device includes the thermal insulation board being connect with spinneret bottom, the thermal insulation board lower part
Cooling holder is connected by telescopic rod, one group of first blowing head is installed on the thermal insulation board, is installed on the cooling holder
One group of second blowing head, first blowing head connect the first feeder, the second gas supply of second blowing head connection
Device, first feeder connect First Heat Exchanger, and second feeder connects the second heat exchanger.
The melt spinning stage cooling device, first blowing head and second blowing head are in respectively
Annular unsymmetrical arrangement.
The melt spinning stage cooling device, first blowing head and second blowing head are tilted towards
The angle of lower installation, angle of inclination and vertical direction is 30-60 °.
The melt spinning stage cooling device, the diameter of the thermal insulation board are not less than the two of spinneret board diameter
Times, first blowing head is mounted on the periphery of the thermal insulation board.
Advantageous effect：
The present invention by the way of sub-sectional cooling, and by flexible between epimere cooling system and hypomere cooling system
Bar connects, and convenient for adjusting the distance between they, different cooling systems is respectively adopted in the thread upper and lower part that spinneret comes out
System, convenient for according to the cooling temperature of different fibre property adjustment and injection intensity, spinning effect is good, high yield rate.
