Description
Technical field
The utility model relates to the equipment for melt spinning and cooling synthetic filaments.
Background technology
The general device that is used for melt spinning and cooling synthetic filaments is disclosed among the CN1930329A.
In the production of synthetic filament, filament all is to be formed by the endless tow of just having extruded in all cases.For this reason, spinning-nozzle is used for by the fine nozzle opening by the melt extrusion long filament of supplying under pressure.Subsequently, the long filament of the appearance of the nozzle plate from spinning-nozzle is cooled and obtains consolidating under the effect of cooling-air.Simultaneously, long filament is pulled and is pulled by means of taking out godet roller until obtain consolidating.Until long filament obtains consolidating these effects of all occuring uniformity and the continuity of long filament linear density there is conclusive impact, perhaps the overall linear density of filament had conclusive impact.Thereby well-known is that particularly during the variation chromatic characteristic by filament was further processed, the fluctuation of the linear density of filament became particularly evident.Owing to quality requirement growing in field of textiles, so should avoid as much as possible this fluctuation of the linear density of long filament.
In known equipment, the long filament that occurs from spinning-nozzle directly enters chilling roll, and this chilling roll utilizes the blowing wall sealing endless tow of gas-permeable.Chilling roll is arranged in the inboard of the quench drum that is connected with the cooling-air source.The cooling-air that conducts to long filament via chilling roll conducts along the filament traffic direction with long filament, and is admitted by the cooling tube of quench drum below.In this case, the cross section of cooling tube narrows down, in order to obtain the extra acceleration of cooling-air.Thereby, can affect the cooling that is in the long filament in the long filament segment fluid flow state and the tractive of long filament.Yet the risk that exists in principle is, because the cross section of cooling tube changes and will form flow distribution in cooling tube.Yet the essential defect of such flow distribution is that under identical condition, not every long filament can be cooled and tractive in endless tow.
Yet, do not produce as much as possible turbulent flow in order to admit the cooling-air stream that occurs from chilling roll with long filament, also known have other system, US3 for example, the system described in 508, the 296A1.The device that is used for melt spinning and cooling long filament known has the cooling tube of closed cylinder wall to arrange along the mode of Axis Extension chilling roll.Be integrated with the separator tube with gas-permeable wall in the cooling tube inboard, described separator tube remains on the cylinder wall of cooling tube at a distance of a distance.Thereby, particularly, can be so that the mobile homogenising of the periphery in the cooling tube.
Yet, in the cooling of the thicker long filament with high long filament linear density, show, for the intensity of the increase of long filament and the speed of increase, in cooling tube, form different pressure conditions.Thereby, it has been determined that in the entrance area of cooling tube the cooling-air that blows out from cooler bin and chilling roll produces malleation with respect to environment.On the contrary, at the port of export place of cooling tube, owing to negative pressure with respect to environment appears in yarn speed larger in the cooling tube.Such pressure reduction causes being cushioned the overlapped flowing effect of pipe compensation.
The utility model content
Therefore, the purpose of this utility model provides the general device for melt spinning and cooling synthetic filaments, so that particularly, can produce the long filament with high long filament linear density, and has the homogenising of height simultaneously in long filament group.
This purpose realizes according to the utility model, it has device for spinning and chilling apparatus, device for spinning has be used at least one spinning-nozzle of extruding long filament, chilling apparatus has at least one chilling roll, at least one chilling roll has the blowing wall of the gas-permeable of arranging coaxially with spinning-nozzle, wherein chilling roll is arranged in the quench drum, quench drum is connected to the cooling-air source, and wherein cooling tube remains on the outside of quench drum in the mode of extending chilling roll, to form rear cooling section, wherein cooling tube has the cylinder wall of gas-permeable, and this cylinder wall is in the scope of 150mm to 500mm in the length in the quench drum outside.
Difference of the present utility model is, forms uniform atmosphere in cooling tube, has avoided peripheral turbulent flow and any pressure reduction in the cooling-air conduction in described atmosphere.Especially that occur and exchange surrounding air bring extra cooling effect to long filament extraly in the lower area of cooling tube.Shown for to surpass the conventional take-off speed compensating differential pressure of 1000m/min, the cylinder wall of the gas-permeable of cooling tube should have the minimum length of 150mm.Can obtain by the support from surrounding air the required cooling effect of high long filament linear density, the length of the cylinder wall of gas-permeable preferably is at most in the scope of 500mm.
In order to carry out compensating operation in the cooling tube with enough long filament stability, preferably implement improvements of the present utility model, wherein to be arranged in spinning-nozzle below scope be distance in the 150mm to 350mm to cooling tube.Thereby according to the thickness of long filament thigh, enough peripheries that can obtain via the cooling-air that chilling roll provides long filament are consolidated.Thereby in all cases, the distance of cooling tube and spinning-nozzle is selected according to the long filament linear density of filament to be produced.
According to another modification of the present utility model, the internal diameter towards the anchor portion of quench drum of cooling tube is in the scope than the large 10mm to 30mm of cladding diameter of the endless tow that enters.Minimum range when the internal diameter of cooling tube should realize that endless tow enters cooling tube between the long filament of cylinder wall and endless tow.Any turbulent flow at the section start of cooling tube has been avoided in such design.Endless tow and be preferably 5mm to 15mm towards the distance between the cylinder wall of the cooling tube at the anchor portion place of quench drum, and depend on the diameter of spinning-nozzle.
