Abstract
The utility model discloses a spinneret realizing intertwining of two components. The spinneret comprises a spinneret core, a drive device, a fixed seat and a melt pipeline, wherein the spinneret core is communicated with the melt pipeline. The spinneret is characterized in that the spinneret core is connected with the fixed seat through bearings; the gear drive device can drive the spinneret core to rotate; the melt pipeline is a double-layer pipeline which is formed by a first pipeline sleeved with a second pipeline; the middle parts of the first and second pipelines are connected through a double-layer pipeline rotating joint in a sealing manner. According to the spinneret, the two pipelines, with one sleeved and connected with the other, are arranged in the spinneret capable of rotating, so as to ensure that melt fibers, sprayed out from a spinneret plate simultaneously, are twisted to a certain degree, and then are intertwined together before the melt fibers are fully solidified; as the fibers which are not fully solidified have certain viscosities, the strength of the intertwined fibers is higher.
Description
Technical field
The utility model belongs to synthetic fiber spinning field, relates in particular to a kind of two component and is wound around spinning head.
Background technology
Spinning head is the integral part for producing continuously the melt spinning device of composite yarn.Spinning head makes that polymer melt is squeezed into many wire long filaments becomes possibility, and long filament some strands is combined to form composite yarn.Therefore such spinning head conventionally has the spinnerets that comprises multiple spinneret orifices on their bottom side, and polymer melt is extruded by this nozzle plate to squeeze out long filament.The material of two kinds of different performances mixed in spinning head or do not mix, obtaining the special fibrous material of performance from spinnerets ejection.The composite fibres such as current sea island filament have been two components or even multi-component material, but how the fibrous material of two components are added before solidifying completely to the bicomponent fibers of certain twist composition twisting.
Summary of the invention
In order to overcome this problem, the utility model provides a kind of two component to be wound around spinning head, for the polymer melt of two kinds of different materials being added in the time just extruding to the spinning head of certain twist.
The technical solution of the utility model is to provide a kind of two component and is wound around spinning head, comprise spinning head core body, drive unit, holder and melt pipe, described spinning head core body is communicated with described melt pipe, and be provided with successively distribution plate, filter screen and spinnerets, it is characterized in that, described spinning head core body is connected with holder bearing, described drive unit can drive described spinning head core body rotation, described melt pipe is the double-skin duct that the first pipeline inner sleeve has second pipe, the mid portion of described the first pipeline and described second pipe adopts double-skin duct swivel joint to be tightly connected.
As preferred version, above described double-skin duct swivel joint, described the first pipeline inner sleeve has described second pipe.
As preferred version, below described double-skin duct swivel joint, described the first pipeline and described second pipe are separated from each other, and separation place is tightly connected.
As preferred version, described drive unit can drive described spinning head core body to rotate on described bearing.
As preferred version, described spinning head core body rotation and the dead in line of described pipeline swivel joint.
As preferred version, what described the first pipeline and described second pipe below walked abreast respectively is provided with the described distribution plate of two covers and described filter screen, and described filter screen directly connects described spinnerets.
As preferred version, described spinnerets is fixed on described spinning head front end, and described spinnerets can be followed described spinning head core body rotation.
As preferred version, described spinnerets is provided with some spinneret orifices.
Of the present utility model pair of component is wound around spinning head, two pipelines that cover connects are mutually set in the spinning head inside that can rotate, make the melt silk simultaneously gushing out from spinnerets add that certain twist is intertwined two kinds of silk threads before solidifying completely, utilize silk thread before solidifying completely to there is certain viscosity and make the silk thread intensity that is intertwined stronger.
Brief description of the drawings

Fig. 2 is the melt pipe structural representation of the utility model embodiment;
In figure: 1. spinning head core body, 2. drive unit, 3. holder, 4. melt pipe, 5. the first pipeline, 6. second pipe, 7. distribution plate, 8. filter screen, 9. spinnerets, 10. spinneret orifice, 11. double-skin duct swivel joints, 12. bearings.
Detailed description of the invention
Below detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, the two components of one of the present utility model are wound around spinning head, comprise spinning head core body 1, drive unit 2, holder 3 and melt pipe 4, spinning head core body 1 is communicated with melt pipe 4, and be provided with successively distribution plate 7, filter screen 8 and spinnerets 9, spinning head core body 1 is connected with holder 3 bearings, drive unit 2 can drive spinning head core body 1 to rotate on bearing 12, spinnerets 9 is fixed on spinning head front end, spinnerets 9 can be followed spinning head core body 1 and be rotated, spinnerets 9 is provided with some spinneret orifices 10, spinning head core body 1 rotation and 11 deads in line of double-skin duct swivel joint.
As described in Figure 2, melt pipe is the double-skin duct that the first pipeline 5 inner sleeves have second pipe 6, the mid portion of the first pipeline 5 and second pipe 6 adopts double-skin duct swivel joint 11 to be tightly connected, above double-skin duct swivel joint 11, the first pipeline 5 inner sleeves have second pipe 6, below double-skin duct swivel joint 11, the first pipeline 5 is separated from each other with second pipe 6, separation place is tightly connected, what the first pipeline 5 and second pipe 6 belows walked abreast respectively is provided with the described distribution plate 7 of two covers and filter screen 8, and filter screen 8 directly connects spinnerets 9.
When the utility model work, two kinds of polymer melts are pressed into melt pipe 4 simultaneously and pass through respectively the first pipeline 5 and second pipe 6, two kinds of polymer melts are squeezed into respectively distribution plate 7 and the filter screen 8 that the first pipeline 5 and second pipe 6 are communicated with separately, finally from the spinneret orifice 10 being communicated with separately, be extruded, form nascent tow.
Drive unit 2 drives spinning head core body 1 to rotate, and double-skin duct swivel joint 11 can keep melt pipe 4 independent stable in the time that spinning head core body 1 rotates, and its inner melt is unaffected.The nascent tow of the bi-material composition of just having been extruded from spinnerets 9 forms parallel a branch of tow, after 1 rotation of spinning head core body, tow is added to certain twist, forms constitutionally stable fiber.
The viscosity of nascent tow is much smaller compared with the viscosity of polymer melt, so tow is had suitable adhesion after twisting, between tow, also can have certain space simultaneously, and the tow of producing like this has lower density and stronger intensity.The nascent tow of two kinds of different materials compositions can be due to the difference of material property simultaneously, and the complementation forming on material property improves the performance entirety of tow.
Above embodiment is only the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
