Detailed Description
Hereinafter, a composite spinning device according to an embodiment of the present invention will be described in detail with reference to the drawings.
First embodiment
A composite spinning device 1 according to a first embodiment of the present invention will be described with reference to fig. 1 to 5.
As shown in fig. 1, the composite spinning apparatus 1 includes: a distribution plate 2 and a spinneret plate 3.
As shown in fig. 1 to 3, the distribution plate 2 is a circular plate having a certain thickness, and has a raw material inflow surface 21, a raw material outflow surface 22, and a screw positioning hole 25.
As shown in fig. 2, the raw material inflow surface 21 is provided with a first manifold groove 211 and a second manifold groove 212. The first confluence groove 211 is located at the center of the raw material inflow surface 21 and has a circular shape. The second bus groove 212 is located on the outer periphery of the first bus groove 211 and has an annular shape. Thus, the first bus bar groove 211 and the second bus bar groove 212 do not interfere. The first raw material B is supplied to the first confluence tank 211, and the second raw material a different from the first raw material B is supplied to the second confluence tank 212.
As shown in fig. 1, since the first confluence groove 211 is gradually inclined from the periphery toward the center when the distribution plate 2 is viewed in cross section, the first raw material B is advantageously gathered toward the center of the first confluence groove 211. Further, when the distribution plate 2 is viewed in cross section, the second collecting groove 212 is inclined gradually from the outer periphery and the inner periphery toward the center, and therefore, the second raw material a is favorably collected toward the center of the second collecting groove 212.
The first bus groove 211 communicates with one end of the first flow channel 23 penetrating the distribution plate 2. Specifically, one end of the first flow channel 23 communicates with an opening located at the center of the first merge groove 211, and the other end of the first flow channel 23 is located at the center of the material outflow surface 22 and has a circular hole shape (see fig. 3).
As shown in fig. 3, a guide groove 222 is provided on the material outflow surface 22. Guide grooves 222 correspond to second manifold grooves 212. In addition, two flow guide grooves 222 are provided, and are respectively located on both sides of the other end of the first flow channel 23. Specifically, the two guide grooves 222 are symmetrical about the other end of the first flow passage 23. That is, the ratio of the number of first flow channels 23 to guide grooves 222 is 1: 2. each of the channels 222 has a Y-shape, a base end 222A (corresponding to the material outflow end) of the Y-shape is adjacent to the other end of the first flow channel 23, and two top ends 222B, 222C (corresponding to the material inflow end) of the Y-shape are located on the same circumference, and the two top ends 222B, 222C are farther from the other end of the first flow channel 23 (the shortest distance) than the base end 222A.
On the other hand, the second confluence groove 212 and the guide groove 222 are communicated by the second flow channel 24 penetrating the distribution plate 2. Specifically, four openings 212a, 212B, 212C, and 212d are provided at equal angles (90 degrees) on the second annular manifold groove 212, and each of the openings 212a, 212B, 212C, and 212d has one second flow channel 24, that is, one end of each second flow channel 24 communicates with the openings 212a, 212B, 212C, and 212d, and the other end of each second flow channel 24 communicates with Y- shaped tips 222B and 222C (corresponding to material inflow ends) of the two guide grooves 222. That is, the ratio of the number of second flow channels 24 to guide grooves 222 is 2: 1.
the screw positioning hole 25 is used for fixing the distribution plate 2 and the spinneret plate 3 by screw positioning. The screw positioning holes 25 are formed in plural, three in the present embodiment, and the three screw positioning holes 25 are arranged on the same circumference and are spaced apart by the same angle (120 degrees). In addition, the screw positioning hole 25 does not interfere with the first flow passage 23 and the second flow passage 24.
As shown in fig. 1 and 4, the spinneret 3 is also a circular plate having a constant thickness, is disposed on the downstream side of the distribution plate 2 so as to be laminated on the distribution plate 2, and combines the first raw material B flowing out from the other end of the first flow path 23 and the second raw material a flowing out from the guide groove 222 to spin the combined in-line ABA two-component fiber. Furthermore, the spinneret plate 3 has three positioning mounting slots 31 and one spinneret hole 32.
The three positioning holes 31 correspond to the three screw positioning holes 25, and the nozzle plate 3 is fixed to the material discharge surface 22 of the distribution plate 2 by inserting screws into the positioning holes 31 and the screw positioning holes 25.
In this case, since the one surface 33 of the spinneret 3 abuts on the raw material outflow surface 22, the second raw material a can be guided by the sealed space formed by the guide grooves 222 and the one surface 33 of the spinneret 3 as a flow path. Specifically, the second raw material a flows from the second confluence groove 212 to the base end 222A (corresponding to the raw material outflow end) of the diversion groove 222 through the second flow channel 24 and the top ends 222B and 222C (corresponding to the raw material inflow end) of the diversion groove 222 in this order by the pressure of the second raw material a.
As shown in fig. 4, the orifice 32 extends through the spinneret plate 3 and is located in the center of the spinneret plate 3. In the present embodiment, since the number of the spinneret holes 32 and the number of the first flow channels 23 are both one, the ratio of the number of the first flow channels to the number of the second flow channels is 1: 1. when the spinneret 3 is fixed to the raw material outflow surface 22 of the distribution plate 2, the spinneret holes 32 overlap the other end of the first flow channel 23 and a part of the two guide grooves 222. Specifically, the spinneret hole 32 overlaps the other end of the first flow channel 23 and the base ends 222A (corresponding to the material outflow ends) of the two guide grooves 222 (see fig. 5). That is, base end 222A (corresponding to the material outflow end) overlaps a portion of orifice 32. As a result, the second raw material a flowing out from the base end 222A can be surely fed into the spinneret 32 so as to be positioned on both sides of the first raw material B flowing out from the other end of the first flow channel 23, and the first raw material B and the second raw material a are combined in the spinneret 32 to form a linear ABA two-component fiber.
Therefore, according to the composite spinning device 1 according to the present embodiment of the present invention, it is possible to achieve in-line ABA two-component spinning of fibers. Moreover, the residence time of the raw materials in the flowing process can be ensured to be short, and the fibers discharged from the spinneret orifices can be ensured to have the same pressure and flow distribution.
Second embodiment
A composite spinning device 10 according to a second embodiment of the present invention will be described with reference to fig. 6 to 10. The main difference between this embodiment and the first embodiment is the number and location of the orifices.
As shown in fig. 6, the composite spinning apparatus 10 includes: a distribution plate 2 and a spinneret plate 3.
As shown in fig. 6 to 8, the distribution plate 2 is a circular plate having a certain thickness, and has a raw material inflow surface 21, a raw material outflow surface 22, and a screw positioning hole 25.
As shown in fig. 7, the raw material inflow surface 21 is provided with a first manifold groove 211 and a second manifold groove 212. The first bus groove 211 has an annular shape. The second manifold groove 212 is composed of an annular outer manifold groove 212A and a circular inner manifold groove 212B. Further, an annular outer bus groove 212A is located on the outer periphery of the first bus groove 211, and a circular inner bus groove 212B is located on the inner periphery of the first bus groove 211. Thus, the first bus bar groove 211 and the second bus bar groove 212 do not interfere. The first raw material B is supplied to the first confluence tank 211, and the second raw material a different from the first raw material B is supplied to the second confluence tank 212.
The first bus groove 211 communicates with one end of the first flow channel 23 penetrating the distribution plate 2. Specifically, five openings 211a, 211b, 211c, 211d, and 211e are provided at equal angles (72 degrees) in the annular first merge groove 211, and one first flow channel 23 is provided for each of the openings 211a, 211b, 211c, 211d, and 211e, that is, one end of each first flow channel 23 communicates with the openings 211a, 211b, 211c, 211d, and 211e, and the other ends of the five first flow channels 23 are provided at equal angles (72 degrees) in the material outflow surface 22 on the same circumference (see fig. 8).
As shown in fig. 8, a guide groove 222 is provided on the material outflow surface 22. Guide grooves 222 correspond to second manifold grooves 212. In the present embodiment, there are ten flow guide grooves 222, and each two flow guide grooves 222 are respectively located on both sides of the other end of the corresponding one of the first flow channels 23, and specifically, each two flow guide grooves 222 are symmetrical with the other end of the corresponding one of the first flow channels 23 as a center. That is, the ratio of the number of first flow channels 23 to guide grooves 222 is 1: 2. each of the channels 222 is Y-shaped, a base end 222A (corresponding to the material outflow end) of the Y-shape is adjacent to the other end of the first flow channel 23, and two top ends 222B, 222C (corresponding to the material inflow end) of the Y-shape are away from the other end of the first flow channel 23. Further, the guide grooves 222 on one side of the first flow passage 23 are provided on the same circumference (outer side), and the guide grooves 222 on the other side of the first flow passage 23 are provided on the other same circumference (inner side).
On the other hand, the second confluence groove 212 and the guide groove 222 are communicated by the second flow channel 24 penetrating the distribution plate 2. Specifically, ten openings are provided in the annular outer confluence groove 212A, and each opening corresponds to one second flow channel 24, that is, one end of each second flow channel 24 communicates with the opening of the outer confluence groove 212A, and the other end of each second flow channel 24 communicates with Y-shaped tips 222B and 222C (corresponding to the material inflow ends) of the five guide grooves 222. In addition, ten openings are also provided in the circular inner confluence groove 212B, and each opening corresponds to one second flow passage 24, i.e. one end of the second flow passage 24 is respectively communicated with the opening of the inner confluence groove 212B, and the other end of the second flow passage 24 is respectively communicated with Y-shaped top ends 222B and 222C (corresponding to the material inflow ends) of the other five diversion grooves 222. That is, the ratio of the number of second flow channels 24 to guide grooves 222 is 2: 1.
the screw positioning hole 25 is used for fixing the distribution plate 2 and the spinneret plate 3 by screw positioning. The screw positioning holes 25 are formed in plural, three in the present embodiment, and the three screw positioning holes 25 are arranged on the same circumference and are spaced apart by the same angle (120 degrees). In addition, the screw positioning hole 25 does not interfere with the first flow passage 23 and the second flow passage 24.
As shown in fig. 6 and 9, the spinneret 3 is also a circular plate having a constant thickness, is disposed on the downstream side of the distribution plate 2 so as to be laminated on the distribution plate 2, and combines the first raw material B flowing out from the other end of the first flow path 23 and the second raw material a flowing out from the guide groove 222 to spin the combined in-line ABA two-component fiber. Furthermore, the spinneret plate 3 has three positioning mounting slots 31 and five spinneret holes 32.
The three positioning mounting holes 31 correspond to the three threaded positioning holes 25, and the spinneret plate 3 is fixed to the material outflow surface 22 of the distribution plate 2 by screwing screws into the positioning mounting holes 31 and the threaded positioning holes 25.
In this case, since the one surface 33 of the spinneret 3 abuts on the raw material outflow surface 22, the second raw material a can be guided by the sealed space formed by the guide grooves 222 and the one surface 33 of the spinneret 3 as a flow path. Specifically, the second raw material a flows from the second confluence groove 212 to the base end 222A (corresponding to the raw material outflow end) of the diversion groove 222 through the second flow channel 24 and the top ends 222B and 222C (corresponding to the raw material inflow end) of the diversion groove 222 in this order by the pressure of the second raw material a.
As shown in fig. 9, five orifices 32 each penetrate the spinneret plate 3 and are arranged on the same circumference at equal angles (72 degrees) apart. In the present embodiment, since the number of the spinneret holes 32 and the number of the first flow channels 23 are both five, the ratio of the number of the first flow channels to the number of the second flow channels is 1: 1. in the case of fixing the spinneret 3 to the raw material outflow surface 22 of the distribution plate 2, each of the spinneret holes 32 overlaps the other end of one of the first flow paths 23 and a part of the two guide grooves 222 corresponding to the other end of the one of the first flow paths 23. Specifically, each of the orifices 32 overlaps the other end of one of the first flow channels 23 and base ends 222A (corresponding to the material outflow ends) of the two guide grooves 222 corresponding to the other end of the one of the first flow channels 23 (see fig. 10). That is, base end 222A (corresponding to the material outflow end) overlaps a portion of orifice 32. As a result, the second raw material a flowing out from the base end 222A can be surely flowed into each of the spinneret holes 32 so as to be positioned on both sides of the first raw material B flowing out from the other end of the first flow channel 23, and the first raw material B and the second raw material a are combined in each of the spinneret holes 32 to form a fiber having two components of linear ABA.
Therefore, according to the composite spinning device 10 according to the present embodiment of the present invention, it is possible to realize in-line ABA two-component spun fibers. Moreover, the residence time of the raw materials in the flowing process can be ensured to be short, and the fibers discharged from the spinneret orifices can be ensured to have the same pressure and flow distribution. In addition, in-line ABA two-component spun fibers can be obtained from multiple orifices.
