The parallel composite fiber spinning assembly is simple in structure, convenient to install, small in melt flow resistance inside, small in sealing contact surface and even in filament discharging.
Description
The technical field is as follows:
the utility model relates to a spinning field specifically says to a composite fiber spinning subassembly side by side.
Background art:
in the process of developing the bi-component parallel composite fiber, the existing matched composite spinning assembly has more problems, such as fast pressure rise of melt inside the assembly, more slurry leakage, short period and the like, so that the spinning broken ends are more, and the stability of the production process and the product quality is greatly influenced.
The utility model has the following contents:
the utility model aims to solve the technical problem that a simple structure, simple to operate are provided, its inside fuse-element flow resistance is little, and composite fiber spinning subassembly side by side of sealing contact surface reduction, this spinning subassembly go out the silk evenly.
The technical solution of the utility model is, a compound fiber spinning subassembly side by side is provided, including cylindric heart-shaped sand cup, be equipped with interior concave cavity and outer cavity on the heart-shaped sand cup, outer cavity and interior concave cavity are concentric circle structure, be equipped with metal sand and filter screen in interior concave cavity and the outer cavity, outer cavity and interior concave cavity bottom are equipped with a plurality of fuse-element runners respectively, the fuse-element runner runs through the lower extreme of heart-shaped sand cup, the heart-shaped sand cup below is still nested there is the spinneret, be equipped with on the spinneret with the heart-shaped sand cup's fuse-element runner complex guiding gutter, the guiding gutter passes through the spinneret orifice intercommunication of terminal surface under guiding hole and the spinneret.
Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: the novel design reduces the melt flowing path of the assembly relative to 5 distribution plate sleeves in the original design, effectively improves the retention and degradation of the melt due to dead angles, improves the smoothness of melt flowing, and achieves the aims of reducing broken ends, prolonging the service cycle of the assembly, reducing plate surface leakage, improving disassembly and assembly efficiency; the novel spinneret plate has the advantages that the mode of fastening 5 pieces of original distribution plates by using a central screw is replaced, and the spinneret plate is designed to be directly connected with a sand cup.
Preferably, the orifices are evenly spaced along a circular ring.
Furthermore, the spinneret plate is concavely provided with an annular positioning groove, and the lower end of the annular sand cup is nested in the positioning groove of the spinneret plate.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
the invention will be further explained with reference to the drawings and the detailed description below:
as shown in fig. 1, a parallel composite fiber spinning assembly comprises a cylindrical annular sand cup 1, an inner concave cavity 11 and an outer concave cavity 12 are arranged on the annular sand cup 1, the outer concave cavity 12 and the inner concave cavity 11 are of concentric circle structures, metal sand and filter screens are distributed in the inner concave cavity 11 and the outer concave cavity 12, a plurality of melt runners are uniformly distributed at the bottoms of the outer concave cavity 12 and the inner concave cavity 11 respectively, the melt runners penetrate through the lower end of the annular sand cup, a spinneret plate 2 is further nested below the annular sand cup 1, a diversion trench communicated with the melt runners of the annular sand cup is arranged on the spinneret plate 2, and the diversion trench is communicated with a spinneret hole 21 on the lower end face of the spinneret plate through the diversion hole. The orifices 21 are evenly spaced along a circular ring. And, for convenient assembly, the spinneret is provided with an annular positioning groove in a concave manner, and the lower end of the annular sand cup is nested in the positioning groove of the spinneret.
When the device is used, two melts A and B respectively enter an inner ring and an outer ring of the annular heart-shaped sand cup, the inner ring and the outer ring are respectively provided with metal sand and a filter screen, wherein the metal sand is arranged above the filter screen, and the melts are homogenized and filtered successively; then, the melt passes through the flow guide groove of the spinneret plate and the flow guide holes and fine filament outlet holes which are uniformly distributed at the lower part of the spinneret plate along the melt flow channel at the bottom of the annular core-shaped sand cup under the action of pressure, then the melt is sprayed out of the spinneret plate surface, two strands of melt are compounded together at the moment of spraying out of the spinneret plate surface to form a composite melt fine flow containing two different components, and then the composite melt fine flow is cooled by side air blowing, oiled and drawn by a hot roller for heat setting, and finally the parallel composite elastic fiber with three-dimensional crimp is formed.
The utility model discloses to the problem that former spinning subassembly exists in the use, from compound spinning technology characteristics, redesigned and improved spinning subassembly. Its main advantage has: 1. the structure is simple, the disassembly is convenient, the number of hard sealing surfaces is reduced, and the slurry leakage problem of the assembly is obviously improved; 2. the newly designed annular core type sand cup replaces 5 pieces of original distribution plates, the filtering volume is larger, the flowing smoothness of a melt is effectively improved, deposition is reduced, degradation is reduced, the assembly period is effectively prolonged, the spinning broken end condition is effectively improved, and the production stability is improved; 3. the arrangement of the spinneret orifices is improved from 2 circles in the original design to 1 circle, the filament outlet is more uniform, and the product quality is obviously improved. In conclusion, the design and improvement achieves good desired results.
The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
