Description

Technical Field

[0001] This invention relates to the field of spinning technology, and in particular to a dual-purpose spinning device. Background Technology

[0002] Wet coagulation spinning, a traditional solution spinning technology, involves directly extruding the spinning solution through a spinneret and immersing it in a coagulation bath. The filaments solidify and form through rapid dual diffusion of the solvent and coagulant at the liquid-phase mass transfer interface. It features mature technology, simple equipment structure, and wide applicability to various polymer systems. Dry-wet coagulation spinning, by incorporating an air gap region, allows the spinning solution to undergo high-ratio pre-stretching and molecular orientation in the air before slow coagulation in the coagulation bath. This significantly improves the roundness of the fiber cross-section and the uniformity of its internal structure, making it suitable for the preparation of high-strength, high-modulus fibers.

[0003] Existing wet and dry-wet coagulation spinning methods cannot achieve process switching or parameter compatibility within the same equipment system, which restricts the versatility and process flexibility of spinning equipment. This also means that the two spinning technologies have long been independent of each other in fiber preparation routes, resulting in redundant construction of production lines and high production costs. Summary of the Invention

[0004] Based on the above analysis, the embodiments of the present invention aim to provide a dual-purpose spinning device to solve the following problems in the prior art: the two spinning technologies have long been independent of each other in the fiber preparation route, resulting in redundant construction of production lines and high production costs; the spinning units of the dual-purpose spinning method have angle differences; the spinning angle of wet spinning cannot be adjusted; the switching between the first spinning head and the second spinning head adopts a threaded disassembly and assembly method, which is inefficient and prone to misoperation; there is friction in the assembly between the connecting cylinder and the sealing ring, and the sealing ring will wear out after long-term use; each rotating bracket needs to be adjusted individually, which is cumbersome and time-consuming; when the curing liquid is injected into the pool, there are air bubbles and impurities in the curing liquid, and the air bubbles carrying impurities will adhere to the surface of the fiber bundle, resulting in poor fiber bundle quality.

[0005] The objective of this invention is mainly achieved through the following technical solutions: A dual-purpose silk-drawing device includes a silk-spinning unit, an angle conversion unit, and a silk-drawing pool unit. The silk-spinning unit is mounted on the angle conversion unit, and both the angle conversion unit and the silk-drawing pool unit are mounted on the ground.

[0006] Furthermore, the spinning unit includes a first spinning head, a second spinning head, and a spinning head seat. The spinning head seat is connected to the angle conversion unit, and the first spinning head or the second spinning head can be detachably connected to the spinning head seat.

[0007] Furthermore, the angle conversion unit includes a fixed bracket and a rotating bracket, with the fixed bracket fixed to the ground.

[0008] Furthermore, the angle conversion unit also includes an angle adjustment component, and the rotating bracket is connected to the fixed bracket through the angle adjustment component.

[0009] Furthermore, the number of the rotating support and the silk-spinning unit is the same, and each is provided in multiples.

[0010] Furthermore, the fiber drawing pool unit includes a pool body and a curing liquid, wherein the curing liquid is contained within the pool body.

[0011] Furthermore, the silk-drawing pool unit also includes a liquid inlet, which is disposed on the outer wall of the pool body.

[0012] Furthermore, it also includes a gas collection unit.

[0013] Furthermore, the gas collection unit includes a gas collection frame and a mesh screen, the gas collection frame being fixed to the inner wall of the pool body, and the mesh screen being taut and fixed to the gas collection frame.

[0014] Furthermore, the air collection unit also includes a filter screen, which is disposed on the inner side of the mesh facing the air collection frame.

[0015] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: (1) The first or second spinning head of the spinning unit of the spinning device of the present invention can be detachably connected to the spinning head seat. The first spinning head can spin the yarn horizontally, and the second spinning head is used for spinning the yarn vertically. By switching between the first and second spinning heads, the spinning angle can be switched horizontally and vertically, thereby matching the requirements of different processes of wet spinning or dry-wet spinning for the spinning angle. The spinning device of the present invention can take into account two process paths, without the need for additional production line layout. It can be used for two purposes in one machine, reducing the construction cost and construction period of the production line. (2) The adjusting bolt of the present invention passes through the rotating bracket and abuts against the side wall of the fixed bracket. The rotating bracket is rotated by screwing the adjusting bolt in or out, thereby finely adjusting the tilt angle of the spinning unit. The rotating bracket can be continuously adjusted within the range of 0° to 20°, respectively for adapting to the second spinning head or the first spinning head. (3) The snap-fit ​​boss of the spinning unit of the present invention can be inserted into the hollow part of the slot along the axial direction of the seat body, and then the snap-fit ​​boss can be screwed into the recess of the slot along the circumferential direction of the seat body at a small angle to complete the locking, thus shortening the assembly time. (4) The sealing ring of the present invention is a movable sealing ring. One end of the sealing ring spring abuts against the sealing ring, and the other end of the sealing ring spring abuts against the inner wall of the seat body. When the connector is inserted, the sealing ring spring drives the sealing ring to connect with the connecting cylinder, which compensates for the wear caused by the sealing ring being connected multiple times and increases the sealing reliability of the sealing ring for long-term use. (5) The push block of the present invention is a magnetic push block; the snap-fit ​​boss is a magnetic snap-fit ​​boss. The magnetic poles of the snap-fit ​​boss and the push block are the same on the opposite side. When the connector is inserted into the seat body, the snap-fit ​​boss and the magnetic push block repel each other with the same pole. The repulsive force pushes the push block and the sealing ring to move along the axial direction of the seat body. The sealing ring can not contact the connecting cylinder, thus preventing the sealing ring from wearing. The snap-fit ​​boss and the push block are linked by magnetic force on the opposite side. There is no mechanical contact between them. The push block can be sealed inside the seat body, reducing the leakage risk of the seat body and improving the overall sealing reliability and service life. (6) The main rod of the angle adjustment component of the present invention rotates, and the actuating arm drives the actuating protrusion to slide along the push-pull groove, thereby pushing each rotating bracket to rotate synchronously around the hinge point of the fixed bracket and the rotating bracket, thereby realizing the synchronous adjustment of the tilt angle of multiple sets of rotating brackets; the actuating protrusion cooperates with the push-pull groove to prevent the angle of the fixed bracket and the rotating bracket from changing after adjustment. (7) The drive screw of the present invention is rotatably mounted on the fixed bracket and meshes with the drive gear; the lead angle of the drive screw is less than or equal to the equivalent friction angle, ensuring that the angles of the fixed bracket and the rotating bracket can be self-locked, thereby increasing the structural stability of the angle conversion unit; (8) The gas collection unit of the present invention is used to collect bubbles and suspended impurities in the curing liquid to improve the quality of the filament bundle; the mesh is used to intercept and capture bubbles and suspended impurities that float with the flow of the curing liquid; the bubbles collected in the gas collection frame are discharged to the outside of the pool through the exhaust hole; the filter screen adopts a multi-layer microporous structure with a decreasing pore size gradient, which can intercept impurities of different particle sizes step by step, and form a double capture barrier with the mesh screen to reduce the defect rate of the filament bundle.

[0016] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the specification or be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained from the content specifically pointed out in the text and accompanying drawings. Attached Figure Description

Detailed Implementation

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0021] Example 1: A specific embodiment of the present invention, such as Figure 1 As shown, a dual-purpose spinning device (hereinafter referred to as the spinning device) is disclosed, including a spinning unit 1, an angle conversion unit 2, and a spinning pool unit 3. The spinning unit 1 is mounted on the angle conversion unit 2, and both the angle conversion unit 2 and the spinning pool unit 3 are mounted on the ground. The filament bundle 100 is pulled out from the spinning unit 1, solidified in the spinning pool unit 3, and then enters the subsequent process. The angle conversion unit 2 is used to change the filament output angle of the spinning unit 1. By switching between the first spinning head 11 or the second spinning head of the spinning unit 1, the spinning device of this embodiment utilizes only one spinning pool unit 3, which can realize both wet spinning and dry-wet coagulation spinning, achieving dual-purpose functionality and reducing the construction cost and construction period of the production line.

[0022] Specifically, such as Figure 2 and Figure 3As shown, the drawing tank unit 3 includes a tank body 31 and a solidifying liquid 32, with the solidifying liquid 32 contained within the tank body 31. In wet spinning, the spinning unit 1 is immersed in the solidifying liquid 32, and the filament bundle 100 is directly ejected from the spinning unit 1 below the liquid surface and solidifies. The drawing tank unit 3 also includes a drawing guide roller 33, which is horizontally positioned on the inner wall of the tank body 31. In dry-wet spinning, the spinning unit 1 is located above the liquid surface of the solidifying liquid 32, and the filament bundle 100 enters the solidifying liquid 32 vertically, undergoing initial forming at the gas-liquid interface before being guided by the drawing guide roller 33 to subsequent processes. The drawing device of this embodiment can accommodate both process paths, eliminating the need for redundant production line construction and reducing production costs.

[0023] When used in wet spinning, the spinning angle of spinning unit 1 is required to have a horizontal inclination angle of 5-15°. However, when used in dry-wet spinning, spinning unit 1 is required to spin vertically downwards. This difference in angle between spinning unit 1 and spinning unit 1 presents a problem in the dual-purpose spinning method. Therefore, preferably, as follows... Figure 4 As shown, the spinning unit 1 includes a first spinning head 11, a second spinning head (not shown in the figure), and a spinning head seat 12. The spinning head seat 12 is connected to the angle conversion unit 2. The first spinning head 11 or the second spinning head can be detachably connected to the spinning head seat 12. The first spinning head 11 can spin silk horizontally, and the second spinning head is used for spinning silk vertically. By switching between the first spinning head 11 and the second spinning head, the horizontal and vertical switching of the spinning angle can be realized, thereby matching the requirements of different processes for the spinning angle.

[0024] To address the issue of the inability to adjust the spin-out angle in wet spinning, preferably, as follows: Figure 5 As shown, the angle conversion unit 2 includes a fixed bracket 21, a rotating bracket 22, and an angle adjustment assembly. The fixed bracket 21 is fixed to the ground, and the rotating bracket 22 is connected to the fixed bracket 21 through the angle adjustment assembly. The angle adjustment assembly includes a fixing bolt 23 and an adjusting bolt 24. The fixing bolt 23 is disposed on the rotating bracket 22 and is used to lock the relative angle between the rotating bracket 22 and the fixed bracket 21. The adjusting bolt 24 passes through the rotating bracket 22 and abuts against the side wall of the fixed bracket 21. The adjusting bolt 24 is screwed in or out to rotate the rotating bracket 22, thereby finely adjusting the tilt angle of the spinning unit 1. The rotating bracket 22 can be continuously adjusted within the range of 0° to 20° to adapt to the second spinning head or the first spinning head 11, respectively.

[0025] Preferably, the rotating support 22 and the spinning unit 1 are arranged one-to-one, and the number of each is set to multiple, so that multiple filament bundles 100 can be extracted in a single spinning pool unit 3.

[0026] Regarding the switching between the first and second spinning heads, using a threaded disassembly method suffers from low efficiency and susceptibility to misoperation. Therefore, preferably, as follows: Figure 4As shown, the spinning unit 1 also includes a connector 13, which is disposed on the first spinning head 11 or the second spinning head. The connector 13 is used for quick connection with the spinning head seat 12.

[0027] Specifically, such as Figure 6 As shown, the connector 13 includes a connecting cylinder 131 and a snap-fit ​​boss 132. One end of the connecting cylinder 131 is connected to the first spinning head 11 or the second spinning head. The snap-fit ​​boss 132 is disposed on the outer periphery of the other end of the connecting cylinder 131. Multiple snap-fit ​​bosses 132 are provided and are evenly distributed along the circumference of the connecting cylinder 131.

[0028] Preferably, the spinneret seat 12 includes a cylindrical seat body 121 and a slot 122. The slot 122 is circumferentially arranged along the inner wall of the seat body 121. The slot 122 and the engaging boss 132 form a radial limiting and axial positioning fit. The engaging boss 132 can be inserted into the hollow part of the slot 122 along the axial direction of the seat body 121. Furthermore, the engaging boss 132 can be screwed into the recess of the slot 122 at a small angle along the circumference of the seat body 121 to complete the locking, thus shortening the assembly time. The rotation angle is 10-45°, depending on the number of engaging bosses 132.

[0029] Each snap-fit ​​boss 132 has a guide slope (not shown in the figure) on its end face to facilitate the alignment and screwing of the snap-fit ​​boss 132 with the snap-fit ​​groove 122.

[0030] To address the issue of loose connection between the spinning head seat 12 and the connector 13, which could lead to leakage of the spinning solution, the spinning head seat 12 preferably includes a sealing ring 123 embedded in the inner wall of the seat body 121. When the connector 13 is inserted, the connecting cylinder 131 can connect with the sealing ring 123 and seal the connector 13.

[0031] To address the issue of wear and tear on fixed sealing rings after repeated use, leading to decreased sealing performance, the sealing ring 123 is preferably a movable sealing ring. The thread-feeding head seat 12 also includes a sealing ring spring 124. One end of the sealing ring spring 124 abuts against the sealing ring 123, and the other end abuts against the inner wall of the seat body 121. When the connecting piece 13 is inserted, the sealing ring spring 124 drives the sealing ring 123 to connect with the connecting cylinder 131, compensating for wear caused by repeated connections of the sealing ring 123 and increasing the sealing reliability of the sealing ring 123 during long-term use.

[0032] To address the friction during assembly between the connecting cylinder 131 and the sealing ring 123, which can lead to wear of the sealing ring 123 over time, a push block 125 is provided on the outer wall of the sealing ring 123 to reduce frictional resistance. The push blocks 125 are evenly distributed circumferentially around the sealing ring 123 and are magnetic. A magnetic locking boss 132 is also provided, with the magnetic poles on the opposite side of the locking boss 132 and the push block 125 being identical. When the connector 13 is inserted into the seat body 121, the snap-fit ​​boss 132 and the magnetic push block 125 repel each other. The repulsive force pushes the push block 125 and the sealing ring 123 inward along the axial direction of the seat body 121, compressing the sealing ring spring 124. The sealing ring 123 does not contact the connecting cylinder 131, preventing wear of the sealing ring 123. When the connector 13 is rotated so that the snap-fit ​​boss 132 is screwed into the slot 122, the side of the snap-fit ​​boss 132 opposite to the push block 125 is misaligned, and the repulsive force weakens. The sealing ring spring 124 rebounds, pushing the sealing ring 123 to fit against the connecting cylinder 131, achieving automatic sealing. The side of the snap-fit ​​boss 132 opposite to the push block 125 is linked by magnetic force, with no mechanical contact between them. The push block 125 can be sealed inside the seat body 121, reducing the risk of leakage in the seat body 121 and improving the overall sealing reliability and service life. Accordingly, the main body 121 is made of copper or polymer material, which combines magnetic conductivity and structural strength.

[0033] Preferably, in order to lock the rotational position of the connector 13 and prevent it from loosening under working vibration, the outer wall of the seat body 121 is provided with an anti-rotation pin groove and an anti-rotation pin 126. The anti-rotation pin 126 is set on the anti-rotation pin groove and can fall down by gravity. When the locking boss 132 is screwed into the locking groove 122, the anti-rotation pin 126 is used to circumferentially stop the locking boss 132, ensuring that the connector 13 cannot rotate circumferentially after being locked.

[0034] Compared with the prior art, in this embodiment, the first spinning head 11 or the second spinning head of the spinning unit 1 can be detachably connected to the spinning head seat 12. The first spinning head 11 can spin yarn horizontally, and the second spinning head is used for vertical spinning. By switching between the first spinning head 11 and the second spinning head, the horizontal and vertical spinning angles can be switched, thereby matching the spinning angle requirements of different processes such as wet spinning or dry-wet spinning. The spinning device in this embodiment can take into account two process paths without the need to add an additional spinning pool unit 3 or adjust the production line layout. It can serve two purposes in one machine, reducing the construction cost and construction period of the production line. The adjusting bolt 24 passes through the rotating bracket 22 and abuts against the side wall of the fixed bracket 21. The adjusting bolt 24 is screwed in or out to realize the rotation of the rotating bracket 22, thereby finely adjusting the tilt angle of the spinning unit 1. The rotating bracket 22 can be continuously adjusted within the range of 0° to 20°, and is used for the second spinning head or the first spinning head 11 respectively; the slot 122 of the spinning unit 1 and the locking boss 132 form a radial limiting and axial positioning fit. The locking boss 132 can be inserted into the hollow part of the slot 122 along the axial direction of the seat body 121, and then the locking boss 132 can be screwed into the recess of the slot 122 along the circumference of the seat body 121 at a small angle to complete the locking, thus shortening the assembly time; the sealing ring 123 is a movable sealing ring, and the spinning head seat 12 also includes a sealing ring spring 124. One end of the sealing ring spring 124 abuts against the sealing ring 123, and the other end of the sealing ring spring 124 abuts against the inner wall of the seat body 121; when the connecting piece 13 is inserted, the sealing ring spring 124 drives the sealing ring 123 to connect with the connecting cylinder 131. To compensate for wear caused by repeated connections of the sealing ring 123 and increase the sealing reliability of the sealing ring 123 during long-term use; the push block 125 is a magnetic push block; the snap-fit ​​boss 132 is a magnetic snap-fit ​​boss, and the magnetic poles of the snap-fit ​​boss 132 and the push block 125 are the same on the opposite side. When the connector 13 is inserted into the seat body 121, the snap-fit ​​boss 132 and the magnetic push block 125 repel each other with the same poles. The repulsive force pushes the push block 125 and the sealing ring 123 to move inward along the axial direction of the seat body 121. The sealing ring 123 can not contact the connecting cylinder 131, preventing the sealing ring 123 from wearing; the snap-fit ​​boss 132 and the push block 125 are linked by magnetic force on the opposite side, and there is no mechanical contact between them. The push block 125 can be sealed inside the seat body 121, reducing the leakage risk of the seat body 121 and improving the overall sealing reliability and service life.

[0035] Example 2: When adjusting the angles of the fixed bracket 21 and the rotating bracket 22 in Embodiment 1, it is necessary to adjust each rotating bracket 22 individually, which is cumbersome and time-consuming. Therefore, as... Figure 4As shown, this embodiment improves the connection between the fixed bracket 21 and the rotating bracket 22 to a hinged connection based on the first embodiment, and improves the angle adjustment component by eliminating the fixing bolt 23 and the adjusting bolt 24 and adding a synchronizing rod 25, which can simultaneously adjust the horizontal tilt angle of multiple rotating brackets 22.

[0036] Specifically, such as Figure 7 As shown, the rotating bracket 22 is provided with a push-pull groove 26. The synchronizing rod 25 includes a main rod body 251, and a plurality of actuating arms 252 and actuating protrusions 253 arranged axially along the main rod body 251. One end of the actuating arm 252 is connected to the main rod body 251, and the other end of the actuating arm 252 is connected to the actuating protrusion 253. The actuating protrusion 253 is embedded in the push-pull groove 26. When the main rod body 251 rotates, the actuating arm 252 drives the actuating protrusion 253 to slide along the push-pull groove 26, pushing each rotating bracket 22 to rotate synchronously around the hinge point of the fixed bracket 21 and the rotating bracket 22, thereby realizing the synchronous adjustment of the tilt angle of multiple sets of rotating brackets 22; the actuating protrusion 253 cooperates with the push-pull groove 26 to prevent the angle of the fixed bracket 21 and the rotating bracket 22 from changing after adjustment.

[0037] Preferably, in order to drive the synchronizing rod 25, the angle adjustment assembly in this embodiment further includes a driving gear 27 and a driving screw 28. The driving gear 27 is coaxially and fixedly connected to the main rod body 251, and the driving screw 28 is rotatably mounted on the fixed bracket 21 and meshes with the driving gear 27. The lead angle of the driving screw 28 is less than or equal to the equivalent friction angle, ensuring that the angles of the fixed bracket 21 and the rotating bracket 22 can be self-locking, thereby increasing the structural stability of the angle conversion unit 2.

[0038] Preferably, the angle conversion unit 2 in this embodiment further includes a drive motor and a reducer (not shown in the figure). The drive motor is linked with the drive screw 28 through the reducer to electrically adjust the angle of the fixed bracket 21 and the rotating bracket 22, saving manpower.

[0039] Compared to Embodiment 1, in this embodiment, the main rod 251 of the angle adjustment component rotates, and the actuating arm 252 drives the actuating protrusion 253 to slide along the push-pull groove 26, pushing each rotating bracket 22 to rotate synchronously around the hinge point of the fixed bracket 21 and the rotating bracket 22, thereby realizing the synchronous adjustment of the tilt angle of multiple sets of rotating brackets 22; the actuating protrusion 253 cooperates with the push-pull groove 26 to prevent the angle of the fixed bracket 21 and the rotating bracket 22 from changing after adjustment; the drive screw 28 is rotatably mounted on the fixed bracket 21 and meshes with the drive gear 27. The lead angle of the drive screw 28 is ≤ the equivalent friction angle, ensuring that the angle of the fixed bracket 21 and the rotating bracket 22 can be self-locking, increasing the structural stability of the angle conversion unit 2.

[0040] Example 3: When the curing liquid 32 is injected into the tank 31, there are air bubbles and impurities in the curing liquid 32. The air bubbles carrying impurities will adhere to the surface of the filament bundle 100, resulting in poor quality of the filament bundle 100. Therefore, as follows: Figure 1 As shown, this embodiment adds a gas collection unit 4 based on embodiment one or embodiment two. The gas collection unit 4 is used to collect bubbles and suspended impurities in the curing liquid 32 to improve the quality of the filament bundle 100.

[0041] Specifically, such as Figure 3 and Figure 8 As shown, the drawing pool unit 3 also includes a liquid inlet 34, which is located on the outer wall of the pool body 31. The gas collection unit 4 includes a gas collection frame 41 and a mesh screen 42. The gas collection frame 41 is a hollow rectangular frame fixed to the inner wall of the pool body 31. The mesh screen 42 is taut and fixed to the gas collection frame 41. The mesh screen 42 is used to intercept and capture air bubbles and suspended impurities that float to the surface as the solidified liquid 32 flows into the gas collection frame 41 through the liquid inlet 34. The top of the gas collection frame 41 is provided with an exhaust hole 43, through which the air bubbles collected in the gas collection frame 41 are discharged to the outside of the pool body 31.

[0042] Preferably, in order to enhance the gas collection and filtration effect, the gas collection unit 4 also includes a filter screen (not shown in the figure). The filter screen is located on the inner side of the mesh 42 near the gas collection frame 41. The filter screen adopts a multi-layer microporous structure with a decreasing pore size gradient, which can intercept impurities of different particle sizes step by step, forming a double capture barrier with the mesh 42. When the solidified liquid 32 flows through the gas collection unit 4, the bubbles continue to rise under the action of buoyancy and are blocked and aggregated by the mesh 42, and then discharged through the exhaust hole 43. The suspended impurities are intercepted by the mesh 42 and the filter screen in tandem, reducing the defect rate of the filament bundle 100.

[0043] Compared to Embodiment 1 or 2, this embodiment adds a gas collection unit 4, which is used to collect air bubbles and suspended impurities in the curing liquid 32 to improve the quality of the filament bundle 100. The mesh 42 is used to intercept and capture air bubbles and suspended impurities that float with the flow of the curing liquid 32. The air bubbles collected in the gas collection frame 41 are discharged to the outside of the pool body 31 through the exhaust hole 43. The filter screen adopts a multi-layer microporous structure with a decreasing pore size gradient, which can intercept impurities of different particle sizes step by step, forming a double capture barrier with the mesh 42. When the curing liquid 32 flows through the gas collection unit 4, the air bubbles continue to float under the action of buoyancy and are blocked and aggregated by the mesh 42, and then discharged through the exhaust hole 43. The suspended impurities are intercepted by the mesh 42 and the filter screen in tandem, reducing the defect rate of the filament bundle 100.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
