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 parts of 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 exist simultaneously. Such fibers not only possess characteristics such as light weight, warmth retention, moisture absorption and sweat discharge, but can also achieve special functions through material combinations.

[0003] Currently, when the existing three-component fiber spinning production devices on the market produce fiber spinning, during the process of extruding and forming filaments by pressurizing through a spinneret plate, when multiple spinneret holes are arranged in a circular pattern, an axial air blowing device is required to cool and solidify the extruded 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 non-solidified filaments near the inner circle, resulting in irregular cross-sections after solidification. 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 solidification temperature, resulting in breakage or inconsistent thickness before and after during subsequent winding and pulling. Moreover, the axial air blowing device blows towards the spinning from the inner side of the spinneret plate to the outside, so the temperature of the wind blown onto 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 this problem. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In the present invention, when the third sleeve blows air outwards, it can cool the freshly extruded fluid spinning at a small air volume and a large range near the extruder. By adjusting the blowing angle and air volume of the third sleeve, the spinning at different positions can be cooled specifically. And during this cooling process, the blowing angle and air volume of the third sleeve blowing air outwards can be adjusted specifically. By changing the included angle between the opening at the end of the third sleeve and the air outlet cover plate, the cold air can specifically pass through the gap of the inner ring molten spinning and blow towards the molten spinning at the middle layer position and the outer layer position arranged in a ring. The cooling distances that the cold air with different flow rates can reach are different, making the acting forces of the inner and outer ring molten spinning blown by the wind uniform, and avoiding the situation of uneven cooling of the inner and outer ring fluids.

[0017] 2. In the present invention, as the rotating ring moves downwards, the plurality of third sleeves move downwards while rotating circumferentially. The circumferential rotation blows air to cool the fluid, further aiming at the characteristic that the freshly extruded molten spinning is easy to deform, and strengthening the cooling effect of small air volume, large range and reducing the acting force on the spinning.

[0018] 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 has already approached the solid state is not easily affected by the wind force and deformed. Therefore, during the downward movement of the rotating ring, the end of the third sleeve can be made closer to the inner-ring molten spinning, and the blowing force of the end of the third sleeve on the molten spinning that has already approached the solid state can be increased, causing the fluid below to be slightly shaken by the wind force, thereby accelerating the cooling speed and the solidification speed.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] 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 out of shape, 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. Moreover, the axial blowing device blows the spinning filaments from the inside of the spinneret to the outside. 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. Please refer to Figure 1 - Figure 8 , a production device for three-component composite hollow fiber spinning, including a confluence device 3, characterized in that: an extruder 5 is fixedly installed on the outer wall of the confluence device 3, a plurality of evenly distributed extrusion holes 6 are opened at the output end of the extruder 5, a cold air device 7 is fixedly installed on the outer wall of the confluence device 3, the output end of the cold air device 7 is fixedly connected to a first bellows 8, one end of the first bellows 8 is fixedly connected to a first rotating piece 12, the outer wall of the first rotating piece 12 is rotatably connected to a rotating ring 13, the outer wall of the rotating ring 13 is rotatably connected to a second rotating piece 14, the outer wall of the second rotating piece 14 is fixedly connected to a second bellows 15, and one end of the second bellows 15 is fixedly connected to a fixed base 10.

[0031] 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.

[0032] 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, the end of the third sleeve 21 is rotatably installed with a hollow ball 22, and a plurality of air holes 23 are opened on the outer wall of the hollow ball 22.

[0033] The outer wall of the third sleeve 21 is fixedly connected with a fixing piece 31, and the outer wall of the fixing piece 31 is fixedly connected with a return spring 32. One end of the return spring 32 is fixedly connected with the inner wall of the rotating ring 13.

[0034] The inner wall of the third sleeve 21 is fixedly connected with a fixing block 24. The outer wall of the fixing block 24 is rotatably connected with a first rotating rod 25, and one end of the first rotating rod 25 is fixedly connected with an eddy current fan 26.

[0035] The outer wall of the eddy current fan 26 is fixedly connected with a second abutting block 27. The second abutting block 27 is arranged as a cylinder, and an abutting inclined surface 28 is formed on the outer wall of the second abutting block 27.

[0036] One end of the third sleeve 21 is fixedly connected with a fixing frame 34. The outer wall of the fixing frame 34 is rotatably connected with a second rotating rod 35. A torsion spring 37 is sleeved on the outer wall of the second rotating rod 35. The outer wall of the second rotating rod 35 is fixedly connected with a rotating block 36. One end of the torsion spring 37 is fixedly connected with the outer wall of the rotating block 36, and the other end of the torsion spring 37 is fixedly connected with the outer wall of the fixing frame 34.

[0037] The outer wall of the rotating block 36 is fixedly connected with an air outlet cover plate 33. 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 with an abutting rod 29. One end of the abutting rod 29 is rotatably installed with a second ball 30, and the abutting rod 29 is located inside the third sleeve 21.

[0038] The outer wall of the confluence device 3 is fixedly connected with a plurality of feed inlets 4. The outer wall of the confluence device 3 is fixedly connected with a guiding cylinder 2, and a spinning production device main body 1 is installed on the outer wall of the guiding cylinder 2.

[0039] In this embodiment: when using the production device for three-component composite hollow fiber spinning, first, three different polymer melts are respectively conveyed into the three feed inlets 4, and are fed into appropriate positions in the confluence device 3 through the feed inlets 4 for confluence. Subsequently, starting the extruder 5 can spray the confluent three polymer melts downward through a plurality of neatly arranged extrusion holes 6 for spinning operation. The axial direction of the ejected fluid simultaneously has three polymers.

[0040] As the melt spinning is ejected downward and sags, at this time, start the cold air blower 7. After the cold air blower 7 is started, it begins to convey cold air into the space jointly formed by the first corrugated pipe 8, the rotating ring 13, the second corrugated pipe 15 and the fixed base 10 through the output end. When the cold air in this space is filled, the cold air will enter the hollow ball 22 through a plurality of air holes 23, and then enter the inside of the third sleeve 21 through the air holes 23 close to the inside of the third sleeve 21, and then blow to the melt spinning in a molten state to cool and shape it.

[0041] During the process of blowing air outward 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. This causes the air flow to blow against the outer wall of the eddy current fan 26 when passing through, making the eddy current fan 26 rotate after being subjected to force. The rotation of the eddy current fan 26 causes 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 cause 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 appendix 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 subjected to abutting force. 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 subjected to force and carry the abutting rod 29 to be forced in a direction away from the second abutting block 27;

[0042] The force on the abutting rod 29 is transmitted to the air outlet cover plate 33, causing the air outlet cover plate 33 to rotate along the outer wall of the fixed frame 34 with the rotating block 36 and the second rotating rod 35. During the rotation process, the torsion spring 37 is tightened, 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 rotates the rotating block 36 and the air outlet cover plate 33 to reset, reducing the angle between the air outlet cover plate 33 and the opening of the third sleeve 21. 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;

[0043] Therefore, as the third sleeve 21 blows air outward, 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 just extruded molten spinning 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 spinning for a long time, and the continuously changing blowing angle can make the blown cold air blow through the gaps between multiple molten spinings to the outer ring molten spinings arranged in a ring, avoiding the problem of uneven cooling degrees of the inner and outer ring molten spinings.

[0044] Embodiment 2. This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figure 1 - Figure 8, the inner wall of the fixed base 10 is fixedly connected with a first abutting block 11;

[0045] The first abutting block 11 is set to have a frustum shape, and one end of the first abutting block 11 is fixedly connected with the inner wall of the first bellows 8.

[0046] In this embodiment: Start the electric telescopic rod 16. After the electric telescopic rod 16 starts, it moves the first rotating piece 12 at the output end downward. During the downward movement of the first rotating piece 12, the first bellows 8 will be stretched. When the first rotating piece 12 moves downward, it synchronously moves the rotating ring 13 downward. When the rotating ring 13 moves downward, it synchronously moves the second rotating piece 14 downward. The downward movement of the second rotating piece 14 causes the second bellows 15 to be gradually compressed.

[0047] 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 causes the first sleeve 17 to move and rotate along the track of the spiral groove 20 while moving downward, prompting the rotating ring 13 to move and rotate along with the first sleeve 17 while moving downward. 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 and cool the fluid, further increasing the blowing range. In view of the characteristic that the freshly extruded molten spinning is easy to deform, the cooling effect with a small air volume and a large range is increased.

[0048] 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 set to have a frustum shape, when the hollow balls 22 slide downward along the frustum outer wall, they will receive a greater abutting force. The abutting force prompts the hollow balls 22 to move the third sleeve 21 in a direction away from the first abutting block 11 under force. At this time, the third sleeve 21 moves the fixing piece 31 to 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 molten spinning at the corresponding position is closer to the solid state. The molten spinning that has approached 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.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
