Description

Technical Field

[0001] The present invention relates to the technical field of spinning production, and specifically relates to a production device for three-component composite hollow fiber spinning. Background Art

[0002] Three-component composite hollow fiber spinning is an advanced chemical fiber preparation technology. By separately conveying three different polymer materials to the same spinning assembly, they converge at appropriate positions in the spinning assembly and are ejected from the same spinneret hole to form a single fiber. Within the same single fiber, along the fiber axis, three polymers coexist. This fiber not only has characteristics such as light weight, warmth retention, moisture absorption and sweat discharge, but can also achieve special functions through material combination.

[0003] Currently, when the existing three-component fiber spinning production devices on the market produce fiber spinning, during the process of pressurizing and ejecting through the spinneret plate to form filaments, when multiple spinneret holes are arranged in a ring, an axial air blowing device is required to cool and solidify the ejected semi-molten filaments. However, when the wind force of the axial air blowing device is too large, it is easy to blow and deform the uncured filaments near the inner circle, resulting in an irregular cross-section after curing. When the wind force of the axial air blowing device is too small, it is easy to cause the filaments after air blowing not to reach the curing temperature, resulting in breakage or inconsistent thickness before and after during subsequent winding and pulling. Moreover, the axial air blowing device blows the spinning from the inner side to the outer side of the spinneret plate. Therefore, the temperature of the spinning at the outer position will increase, resulting in uneven cooling of the inner and outer circles of the spinning. Therefore, a three-component fiber spinning production device is needed to solve the problem. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, when the third sleeve blows air outward, the fluid spinning just extruded can be cooled in a small amount and over a large range at a position close to the extruder. By adjusting the blowing angle and air volume of the third sleeve, the spinning at different positions can be cooled in a targeted manner. In this cooling process, the blowing angle and air volume of the third sleeve can be adjusted in a targeted manner. By changing the angle between the opening at the end of the third sleeve and the air outlet cover, the cold air can be blown through the gap of the inner circle molten spinning to the molten spinning at the middle layer and outer circle positions of the annular arrangement. The cooling distances that can be achieved by cold air of different flow rates are different, so that the molten spinning of the inner and outer circles is evenly acted upon by the wind, thereby avoiding uneven cooling of the inner and outer circle fluids.

[0015] 2. In the present invention, as the rotating ring moves downward, multiple third sleeves move downward while rotating in a circle, and the circular rotation cools the fluid by blowing air, further targeting the characteristics of the just-extruded molten spinning that is easy to deform, and strengthens the cooling effect of small air volume, large range, and reducing the force on spinning.

[0016] 3. In the present invention, as the rotating ring moves downward, since the molten spinning at the corresponding position is closer to the solid state, the molten spinning that is already close to the solid state is not easily affected by the wind force and deformed. Therefore, during the downward movement of the rotating ring, one end of the third sleeve can be made closer to the inner-ring molten spinning, and the blowing force of one end of the third sleeve on the molten spinning that is already close to the solid state can be increased, so that the fluid below is slightly shaken by the wind force, accelerating the cooling speed and the solidification speed.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Embodiment 1. This embodiment helps to solve the problem that when the wind force of the axial blowing device is too large, it is easy to blow the uncured filaments near the inner circle and deform them, resulting in an irregular cross-section after curing. When the wind force of the axial blowing device is too small, it is easy to cause the filaments passing through the blowing to not reach the curing temperature, resulting in breakage or inconsistent thickness before and after during subsequent winding and pulling. And the axial blowing device blows the spinning filaments from the inner side of the spinneret to the outer side. Therefore, the temperature of the wind blown to the spinning filaments in the outer position will increase, resulting in uneven cooling of the inner and outer circles of the spinning filaments.

[0022] An electric telescopic rod 16 is fixedly installed in the inner wall of the first bellows 8, and the output end of the electric telescopic rod 16 is fixedly connected to the outer wall of the first rotating piece 12.

[0023] A plurality of third sleeves 21 are slidably connected to the inner wall of the rotating ring 13, the plurality of third sleeves 21 penetrate the rotating ring 13, a hollow ball 22 is rotatably installed at the end of the third sleeve 21, and a plurality of air holes 23 are opened on the outer wall of the hollow ball 22.

[0024] A fixing piece 31 is fixedly connected to the outer wall of the third sleeve 21, a return spring 32 is fixedly connected to the outer wall of the fixing piece 31, and one end of the return spring 32 is fixedly connected to the inner wall of the rotating ring 13.

[0025] A fixing block 24 is fixedly connected to the inner wall of the third sleeve 21 , a first rotating rod 25 is rotatably connected to the outer wall of the fixing block 24 , and a vortex fan 26 is fixedly connected to one end of the first rotating rod 25 .

[0026] A second abutment block 27 is fixedly connected to the outer wall of the vortex fan 26 . The second abutment block 27 is configured as a cylinder, and an abutment slope 28 is formed on the outer wall of the second abutment block 27 .

[0027] One end of the third sleeve 21 is fixedly connected to a fixed frame 34, an outer wall of the fixed frame 34 is rotatably connected to a second rotating rod 35, an outer wall of the second rotating rod 35 is sleeved with a torsion spring 37, an outer wall of the second rotating rod 35 is fixedly connected to a rotating block 36, one end of the torsion spring 37 is fixedly connected to the outer wall of the rotating block 36, and the other end of the torsion spring 37 is fixedly connected to the outer wall of the fixed frame 34.

[0028] The outer wall of the rotating block 36 is fixedly connected to an air outlet cover plate 33, and the outer contour of the air outlet cover plate 33 matches the contour of the opening at the end of the third sleeve 21. The outer wall of the air outlet cover plate 33 is fixedly connected to a resistance rod 29, and a second ball 30 is rotatably installed at one end of the resistance rod 29. The resistance rod 29 is inside the third sleeve 21.

[0029] A plurality of feed ports 4 are fixedly connected to the outer wall of the combiner 3 , a guide cylinder 2 is fixedly connected to the outer wall of the combiner 3 , and a spinning production device body 1 is installed on the outer wall of the guide cylinder 2 .

[0030] In this embodiment: when using a three-component composite hollow fiber spinning production device, first, three different polymer melts are respectively conveyed to three feed ports 4, and then conveyed to the appropriate position of the combiner 3 through the feed ports 4 for convergence, and then the extruder 5 is started to spin the merged three polymer melts downward through a plurality of neatly arranged extrusion holes 6, and the ejected fluid has three polymers in the axial direction at the same time.

[0031] As the molten spinning sprays downward and droops, the air cooler 7 is started. After the air cooler 7 is started, cold air is delivered through the output end to the space formed by the first bellows 8, the rotating ring 13, the second bellows 15 and the fixed base 10. When the cold air in this space is filled with cold air, the cold air enters the hollow ball 22 through multiple air holes 23, and then enters the third sleeve 21 through the air holes 23 close to the inside of the third sleeve 21, and then blows toward the molten molten spinning to cool and shape it.

[0032] During the process of blowing air outwards through the third sleeve 21, when the air flow passes through the narrow inner wall of the third sleeve 21, it has a relatively high flow rate. When the air flow passes through, it blows the outer wall of the eddy current fan 26, causing the eddy current fan 26 to rotate after being stressed. The rotation of the eddy current fan 26 drives the first rotating rod 25 to rotate synchronously along the outer wall of the fixed block 24. Moreover, the rotation of the eddy current fan 26 will drive the second abutting block 27 to rotate synchronously. The rotation of the second abutting block 27 causes the abutting inclined surface 28 formed on the outer wall of the second abutting block 27 to abut against the second ball 30. It should be noted that the abutting inclined surface 28 is an inclined surface obliquely formed at the end of the second abutting block 27, as shown in the attached Figure 7 As shown in the figure, in the initial state, the position of the second ball 30 is at the lower position of the inclined surface of the abutting inclined surface 28, and the second ball 30 is in a state where it is not subject to the abutting effect. When the second abutting block 27 rotates, the abutting inclined surface 28 gradually abuts the higher position of the inclined surface against the second ball 30, causing the second ball 30 to be stressed and drive the abutting rod 29 to be stressed in a direction away from the second abutting block 27; The force of the abutting rod 29 is transmitted to the air outlet cover plate 33, causing the air outlet cover plate 33 to drive the rotating block 36 and the second rotating rod 35 to rotate along the outer wall of the fixed frame 34, and the torsion spring 37 is tightened during the rotation process, facilitating subsequent resetting. When the second abutting block 27 rotates and gradually makes the lower position of the abutting inclined surface 28 abut against the second ball 30, the abutting force of the abutting inclined surface 28 on the second ball 30 is gradually released. At this time, the torsion spring 37 resets and drives the rotating block 36 and the air outlet cover plate 33 to rotate and reset, reducing the angle between the air outlet cover plate 33 and the opening of the third sleeve 21. At this time, at the same flow rate in the third sleeve 21, the air outlet area is reduced, that is, the flow rate of the air outlet will increase; Therefore, as the third sleeve 21 blows air outwards, the air outlet cover plate 33 will rotate back and forth and reset by a certain angle, increasing and then decreasing the angle between the opening at one end of the third sleeve 21 and the air outlet cover plate 33. At this time, the blowing angle from one end of the third sleeve 21 becomes larger and then gradually smaller. As the angle and size of the air outlet continuously change, the wind force blown out from one end of the third sleeve 21 at the same flow rate will continuously change, and the blowing angle is also continuously changing. It should be noted that the rotating ring 13 is located close to the extruder 5, and can blow and cool the molten spun fiber just extruded from the extruder 5 with a small air volume and a large range. Continuously changing the blowing angle can prevent the third sleeve 21 from blowing directly at the inner ring molten spun fiber for a long time, and the continuously changing blowing angle can make the blown cold air blow through the gaps between multiple molten spun fibers to the outer ring molten spun fibers arranged in a ring, avoiding the problem of uneven cooling of the inner and outer ring molten spun fibers.

[0033] Example 2. This example is an improvement made on the basis of Example 1. Specifically, please refer to Figure 1 - Figure 8 , a first abutting block 11 is fixedly connected to the inner wall of the fixed base 10; The first abutting block 11 is arranged in the shape of a frustum of a cone, and one end of the first abutting block 11 is fixedly connected to the inner wall of the first corrugated pipe 8.

[0034] In this embodiment: The electric telescopic rod 16 is started. After the electric telescopic rod 16 is started, it drives the first rotating piece 12 at the output end to move downward. During the downward movement of the first rotating piece 12, the first corrugated pipe 8 will be stretched. When the first rotating piece 12 moves downward, it drives the rotating ring 13 to move downward synchronously. When the rotating ring 13 moves downward, it drives the second rotating piece 14 to move downward synchronously. The downward movement of the second rotating piece 14 causes the second corrugated pipe 15 to be gradually compressed.

[0035] As the rotating ring 13 moves downward, the first sleeve 17 on the outer wall of the rotating ring 13 moves downward together. When the first sleeve 17 moves downward, the first ball 18 rotatably installed on the outer wall slides along the track of the spiral groove 20. Since the spiral groove 20 is a spiral groove, the first ball 18 drives the first sleeve 17 to move downward and rotate along the track of the spiral groove 20, prompting the rotating ring 13 to move downward and rotate along with the first sleeve 17. First, the rotation of the rotating ring 13 causes the plurality of third sleeves 21 to rotate circumferentially, so that the air outlet end of the third sleeve 21 rotates circumferentially to blow air and cool the fluid, further increasing the blowing range. In view of the characteristic that the just-extruded molten spinning is easy to deform, the cooling effect with small air volume and large range is increased.

[0036] As the rotating ring 13 moves downward, the hollow balls 22 at one end of the plurality of third sleeves 21 slide downward along the outer wall of the first abutting block 11. Since the first abutting block 11 is arranged in the shape of a frustum of a cone, when the hollow balls 22 slide downward along the outer wall of the frustum, they will receive a greater abutting force. The abutting force prompts the hollow balls 22 to drive the third sleeves 21 to move away from the first abutting block 11 under force. At this time, the third sleeve 21 drives the fixing piece 31 to move and compress the return spring 32, so that more parts of the third sleeve 21 penetrate through the rotating ring 13 and are exposed outside, that is, one end of the third sleeve 21 is closer to the molten spinning. It should be noted that as the rotating ring 13 moves downward, the corresponding molten spinning is closer to the solid state. The molten spinning that has been close to the solid state is not easily affected by the wind and deformed. Therefore, the end of the third sleeve 21 closer to the molten spinning can apply a greater wind force to the outer wall of the molten spinning.
