Abstract
The invention relates to the technical field of chemical fiber spinning machines, in particular to a spinning assembly capable of removing flow dead points of a melt. The spinning assembly comprises an upper overflowing cover, an assembly cover, an assembly body, a sand cup and a spinneret plate, wherein the sand cup is an annular sand cup; an inner chamber of the annular sand cup is an annular inner chamber; and filter sand is filled into the annular inner chamber. In the spinning assembly, the annular sand cup is adopted, a lower overflowing cover is canceled, and a formed annular filter cross section provides a uniform melt for the spinneret plate and removes the flow dead points of the melt in a nonporous central area of the spinneret plate, so that the phenomena of broken filaments and end breakage in the process of producing a fiber dividing mother yarn are avoided.
Description
Technical field
The present invention relates to chemical fibre spinning field of mechanical technique, be specifically related to a kind of filament spinning component that can eliminate flow dead points of melt.
Background technology
In a minute fine female silk fiber was produced, the general employing was the fine female silk special spinning jet of branch that outer ring one circle has plate hole, and this spinnerets has the central area of atresia.Traditional production divides the filament spinning component of fine female silk, as shown in Figure 1, polyester fondant enters sand cup 5 by last overcurrent plate 12, circular distribution plate through sand cup 5 bottoms, overcurrent plate 13 has only a circle that fine female special spinning jet 9 conveyings of branch of plate hole are arranged to the outer ring under the warp again, thereby in spray silk process, produce flow dead points of melt inevitably, cause the generation of lousiness and broken end phenomenon.Be not only the special spinning jet that has the atresia central area and easily produce flow dead points of melt, the existence of following overcurrent plate 13 also is the key factor that produces flow dead points of melt.
Summary of the invention
The problem to be solved in the present invention provide a kind of filament spinning component that in minute fine female silk fiber production, can eliminate flow dead points of melt.
In order to achieve the above object, the technical solution used in the present invention is: a kind of filament spinning component that can eliminate flow dead points of melt, can comprise overcurrent lid, module cover, assembly body, sand cup and spinnerets, described sand cup is the ring-shaped sand cup, the inner chamber of described ring-shaped sand cup can be annular cavity, the center of described ring-shaped sand cup is solid, is filled with filter sand in the described annular chamber.
In the such scheme, described ring-shaped sand cup bottom can be provided with inclined hole.
In the such scheme, the intracavity bottom of described ring-shaped sand cup can be provided with first annular filter screen.
In the such scheme, between described ring-shaped sand cup and the spinnerets, the following of inclined hole can be provided with second annular filter screen.
In the such scheme, can be provided with O-ring seal between described first annular filter screen and the ring-shaped sand cup internal chamber wall.
In the such scheme, described ring-shaped sand cup bottom can be provided with two circle inclined holes.
By filament spinning component provided by the invention, can be spinnerets uniform melt is provided, eliminated the flow dead points of melt of the central area of spinnerets atresia, divide lousiness and broken end phenomenon in fine female silk production process thereby eliminated.
Description of drawings
Fig. 1 is the structural representation of filament spinning component in the prior art;
A kind of structural representation that can eliminate the filament spinning component of flow dead points of melt that Fig. 2 provides for the embodiment of the invention.
The specific embodiment
Below in conjunction with drawings and Examples technical solution of the present invention is described in detail.
As shown in Figure 2, the embodiment of the invention provides a kind of filament spinning component that can eliminate flow dead points of melt, and it comprises overcurrent lid 1, module cover 2, assembly body 3, sand cup 5 and spinnerets 9.Module cover 2 will go up overcurrent lid 1, sand cup 5 and spinnerets 9 and be fixed in the assembly body 3.Sand cup 5 is the ring-shaped sand cup.The inner chamber of ring-shaped sand cup is an annular cavity, is filled with filter sand 4 in the annular chamber.The solid section 11 at ring-shaped sand cup center has replaced the overcurrent plate of going up of the prior art, makes more compact structure.
Ring-shaped sand cup bottom is provided with two circle inclined holes 10.The intracavity bottom of ring-shaped sand cup is provided with first annular filter screen 7.Between ring-shaped sand cup and the spinnerets 9, the below of inclined hole 10 is provided with second annular filter screen 8.Can be provided with O-ring seal 6 between first annular filter screen 7 and the ring-shaped sand cup internal chamber wall.
The last overcurrent lid 1 of polyester fondant process enters the ring-shaped sand cup, filters through the filter sand 4 and first annular filter screen 7, enters the inclined hole 10 of ring-shaped sand cup bottom, and then 8 filtrations evenly enter the spinnerets 9 that has only one girth sheets hole, outer ring through second annular filter screen.
The present invention adopts the ring-shaped sand cup, has not only cancelled the setting of last overcurrent plate and following overcurrent plate, and is structurally more simple, compact.The annular filter cross section that this structure forms for spinnerets provides uniform melt, has been eliminated the flow dead points of melt of the central area of spinnerets atresia, thereby has eliminated lousiness and broken end phenomenon.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
