Abstract
The utility model discloses a spinneret device comprising a spinneret and a sand cup, wherein two sealed cavities are arranged at the combination part of the spinneret and the sand cup; and each sealed cavity is internally provided with a sealing ring. The spinneret device is characterized in that the two sealed cavities are separated by the sealing rings. As for the spinneret device, a bulge between the two sealed cavities in the prior art is eliminated, so that the width of a segment belt can be reduced and an annular blowing effect is ensured; in addition, when a component is assembled, the pressure between the spinneret and the sand cup can be maintained within a range of 20MPa-50MPa by a thread ring at the upper part of the component so as to conduct mechanically forced seal; when the component is placed on a machine to use, melt enters the sealed cavities between the sand cup and the spinneret; and as pressure of 8.0Mpa-13.0Mpa is formed in a spinneret hole, the sealing rings are adhered to a gap between the spinneret and the sand cup to conduct excellent self seal; therefore, a double-sealing effect is achieved, and the spinneret device is specially suitable for producing fine denier filaments of 72f and above.
Description
Technical field
The utility model relates to a kind of spinnerets device.
Background technology
Spinnerets adopts component pressure to carry out self sealss fully in the world at present, for the melt of avoiding two cavitys in the assembly interpenetrates, be provided with a sealing in the middle of the spinnerets with protruding, width that generally should projection is 3-4mm, use the thick sealing ring of 1.5mm in two cavitys respectively, consider sealing ring deflection 0.5mm, pinning hole limit between two cavitys is 8-9mm to the minimum distance between the limit, the diameter of pinning hole is 2mm, spinneret orifice center beeline between such two cavitys (be called cut apart bandwidth at this) is 11-12mm, find through test of many times, when this is cut apart bandwidth and surpasses 10mm, encircling blast-cold but the time, can not form good annular blowing effect, especially 144f fiber, the tow instability, fracture of wire is many, inferior quality, sealing difficulty between spinnerets and the sand cup in addition, spillage easily between spinnerets and the assembly is difficult to satisfy the production demand.
Summary of the invention
The purpose of this utility model is a kind of good seal performance that provides for the deficiency that solves above-mentioned technology, the spinnerets device that can guarantee annular blowing effect.
In order to achieve the above object, the spinnerets device that the utility model is designed comprises spinnerets and sand cup, and the junction between spinnerets and the sand cup is provided with two annular seal spaces, be provided with sealing ring in the annular seal space, it is characterized in that described two annular seal spaces separate by sealing ring.Therefore consider that two pressure between the annular seal space are close, cancelled in the prior art projection between two annular seal spaces, separating by sealing ring between two annular seal spaces cut apart bandwidth thereby can dwindle, and maximum can be dwindled 4mm.
As preferably, described sealing ring is the alumiseal circle.
As preferably, described spinnerets is provided with cuts apart band, cutting apart bandwidth is 7mm～10mm, in order to reach but effect of good ring blast-cold, cutting apart bandwidth according to the kind needs can select between 7mm～10mm, cut apart band and dwindle and to significantly improve the cooling uniformity that improves fiber, especially satisfy the production needs of 144f kind.
As preferably, to cut apart the band both sides on the described spinnerets and be provided with spinneret orifice, spinneret orifice is circumferential arrangement.
The utility model resulting spinnerets device has been cancelled in the prior art projection between two annular seal spaces, and separating by sealing ring between two cavitys cut apart bandwidth thereby can dwindle, and guarantees annular blowing effect; In addition, during component assembling, can keep pressure 20MPa-50MPa between this spinnerets and the sand cup by assembly top threaded collar, carry out the mechanical forced sealing, when assembly uses on the machine, when melt enters annular seal space between sand cup and the spinnerets, because spinneret orifice forms the pressure of 8.0MPa-13.0MPa, makes and carries out self sealss well in slit between sealing ring applying spinnerets and the sand cup, thereby reach the dual-seal effect, sealing property is better.The quality and the stability requirement of on a spinnerets, producing two section chief's silks simultaneously be can satisfy, 72f and above fine denier filament are particularly useful for producing.

Wherein: sealing ring 1, cut apart and be with 2, sand cup 3, annular seal space 4, spinnerets 5.
The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1:
As shown in Figure 1 and Figure 2, the described spinnerets device of present embodiment comprises spinnerets 5 and sand cup 3, and the junction between spinnerets 5 and the sand cup 3 is provided with two annular seal spaces 4, is provided with sealing ring 1 in the annular seal space 4, and described two annular seal spaces 4 separate by sealing ring 1.Therefore consider that two pressure between the annular seal space 4 are close, cancelled in the prior art projection between two annular seal spaces 4, separating by sealing ring between two annular seal spaces 4 is with 2 width thereby can dwindle to cut apart, and maximum can be dwindled 4mm, guarantees the annular effect of drying.Described sealing ring 1 is the alumiseal circle, and described spinnerets 5 is provided with the two-in-one spinnerets of cutting apart with 2 for middle, cuts apart and is with 2 width to equal 7mm, cuts apart on the described spinnerets 5 and is with 2 both sides to be provided with spinneret orifice, and spinneret orifice is circumferential arrangement totally 10 circles.
During component assembling, spinnerets 5 is installed earlier in package shell, sealing ring 1 is installed again, secondly after installing sand cup 3 and other part, compress the sealing ring 1 between spinnerets 5 and the sand cup 3 with hydraulic press, and keeping pressure 20MPa-50MPa between this spinnerets 5 and the sand cup 3 by assembly top threaded collar, this is the mechanical forced sealing.When assembly uses on the machine, when melt enters annular seal space 4 between sand cup 3 and the spinnerets 5,, make slit between sealing ring 1 applying spinnerets 5 and the sand cup 3 because spinneret orifice forms the pressure of 8.0MPa-13.0MPa, this is self sealss, thereby reaches the dual-seal effect.
The resulting spinnerets device of the utility model, make sealing ring 1 fit to the junction between spinnerets 5 and the sand cup 3, reach the dual-seal effect between spinnerets 5 and the sand cup 3, has excellent sealing performance, and guarantee favorable cooling effect, satisfy the quality and the stability requirement of on a spinnerets, producing two section chief's silks simultaneously, be particularly useful for producing 72f and above fine denier filament.
