Description

Technical Field

[0001] This invention relates to the field of textile technology, and in particular to a spinning roller, a spinning device, and a spinning machine. Background Technology

[0002] As a production equipment for producing new textile raw materials, the existing continuous spinning machines produce rayon products that are more stable in quality and performance than traditional yarns, making them more suitable for manufacturing high-end products. With the continuous improvement of people's living standards, the demand for such products is also increasing. However, the current production capacity of continuous spinning machines on the market is gradually failing to meet the market demand.

[0003] Existing spinning machines use a small roller for each filament, with four filaments sharing four small rollers, plus a large-diameter common roller, for a total of five processing rollers. The drawback of this type of spinning machine is that increasing the number of filaments requires increasing the number of small-diameter rollers, resulting in high investment, large footprint, low output, and high production costs, making it difficult to increase the spinning machine's capacity.

[0004] For example, the invention patent with application number CN03118752.8 discloses the spinning process of a continuous spinning machine for viscose rayon, which mainly includes the following process: viscose is ejected from the spinneret hole of the spinneret through the viscose tube, metering pump, filter, spinneret seat, and spinneret, and solidified into filaments in the coagulation bath. After being formed in a forming tube filled with the coagulation bath, the filaments coming out of the forming tube pass through the acid scraping device and are spirally wound along the axis of a pair of rollers consisting of a common roller and a small diameter roller with a certain included angle on their axes, and come out from the other end; the pair of rollers consists of a common roller and at least two small diameter rollers in pairs; each filament passes around the common roller, and at least two filaments passing around the common roller pass around the same small diameter roller.

[0005] Although the spinning machine disclosed in this application allows more than two filaments to pass over each small-diameter roller, thus increasing the number of filaments without increasing the number of small-diameter rollers, thereby improving production efficiency, reducing production costs and equipment investment, and decreasing the floor space required for production equipment, the fact that two filaments run on a single small-diameter roller makes it prone to filament bundling. This can also affect the normal operation of other filaments, resulting in poor stability and potentially causing significant quality problems with double-stranded filaments.

[0006] In view of this, the present invention is hereby proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a spinning roller that can run multiple filaments on each spinning roller at the same time without producing filament tangling.

[0008] To achieve this objective, according to one aspect of the present invention, the present invention adopts the following technical solution:

[0009] A spinning roller includes: a spinning roller body capable of spinning at least two filaments simultaneously;

[0010] From one end to the other, multiple spiral feeding grooves are spirally arranged on the peripheral wall of the spinning roller body. Adjacent spiral feeding grooves are independently arranged for individual feeding.

[0011] Furthermore, the spinning roller body can spin two filaments simultaneously, and the spiral feeding groove includes a first spiral feeding groove and a second spiral feeding groove that can operate each filament independently. The first spiral feeding groove and the second spiral feeding groove extend spirally from one end of the spinning roller body to the other end.

[0012] Preferably, the bottom walls of the first and second spiral feeding grooves are at different vertical distances from the central axis of the spinning roller body.

[0013] Furthermore, a spiral boss is provided on the peripheral wall of the spinning roller body, extending spirally from one end of the spinning roller body to the other end, and the first spiral feeding groove is formed on the spiral boss; the groove structure formed between two adjacent spiral bosses and the peripheral wall of the spinning roller body forms the second spiral feeding groove.

[0014] Preferably, the first spiral wire feeding groove is a curved groove formed on the top wall of the spiral boss.

[0015] Another object of the present invention is to provide a spinning device having any of the above-described spinning rollers, the spinning device comprising a plurality of the above-described spinning rollers and a processing roller with a diameter larger than the spinning rollers, the processing roller and each spinning roller corresponding one-to-one to form a plurality of pairs of rollers, at least two filaments alternately passing through the spinning rollers and the processing roller, each filament being spirally wound from one end of the pair of rollers to the other end along its corresponding spiral feeding groove;

[0016] Preferably, the number of spinning rollers is 4-8; more preferably, the number of spinning rollers is 4.

[0017] Furthermore, along the direction of the filament's travel, the processing roller includes a drying section and a cooling section sequentially disposed at its end; the drying section is provided with a heating structure, and the cooling section is provided with a cooling structure.

[0018] When the filament passes the end of the processing roller, the heating structure dries the filament before it enters the drying section. After drying, the cooling structure cools the filament before it enters the cooling section.

[0019] Furthermore, the drying section and cooling section of the processing roller are made of metal thermally conductive material, and the heating structure includes a heat-conducting pipe. The heat-conducting pipe is coiled on the inner peripheral wall of the processing roller located in the drying section. The filaments entering the drying section are dried by injecting a heating medium into the heat-conducting pipe.

[0020] The cooling structure includes a cooling pipe, which is coiled on the inner circumferential wall of the processing roller located in the cooling section. The filaments entering the cooling section are cooled by injecting a cooling medium into the cooling pipe.

[0021] Furthermore, the end of the processing roller is tapered, allowing the filament to retract and solidify as it passes through the tapered portion of the processing roller.

[0022] Preferably, the end of the processing roller is designed with a tapered shape where the outer diameter gradually decreases.

[0023] More preferably, the processing roller with a frustoconical end has a cone angle of α, where: 4°≤α≤10°.

[0024] Another object of the present invention is to provide a spinning machine having any of the spinning apparatuses described above, wherein...

[0025] The spinning machine also includes a winding device, and the filaments processed by the spinning device are guided by the filament guiding mechanism to the winding device and wound into a cylinder.

[0026] Furthermore, the winding device includes an upper winding machine and a lower winding machine, wherein the upper winding machine and the lower winding machine have multi-spindle winding machines;

[0027] The positions of the upper and lower winding machines can be set in a one-to-one correspondence between the upper and lower layers; or the upper and lower winding machines can be arranged in a staggered manner, and the number of upper and lower winding machines can be freely combined.

[0028] Preferably, the total number of winding machines is 8-16, and the upper and lower winding machines are arranged in a staggered manner;

[0029] More preferably, the total number of winding machines is 8, with 4 winding machines in each of the upper and lower layers, and they are arranged in a staggered manner.

[0030] Furthermore, the upper winding machine includes a housing and a winding head and a winding motor disposed within the housing, wherein each upper winding head is driven by a winding motor.

[0031] The winding head also includes a winding drum for winding the filament into a cylinder. A first toothed pulley is provided on the output shaft of the winding motor, and a second toothed pulley is provided on the winding shaft of the winding drum. The first toothed pulley and the second toothed pulley are connected by a synchronous gear belt drive.

[0032] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0033] 1. The spinning machine provided by the present invention allows multiple filaments to travel on each spinning roller, which reduces costs and further improves the production efficiency of the spinning machine. Furthermore, by opening multiple spiral feeding grooves on the outer surface of the spinning roller body, the filaments travel on separate spiral feeding grooves, effectively avoiding the phenomenon of filament tangling that easily occurs when multiple filaments run on the same spinning roller, thus increasing output while effectively ensuring the quality of the filaments.

[0034] 2. The spinning machine provided by this invention has a drying section at the end of the processing roller for drying the filaments and a cooling section for cooling the filaments. The filaments can be dried and cooled simultaneously while being spun on the spinning roller and the processing roller, eliminating the need for separate drying and cooling rollers. This simplifies the overall structure of the spinning machine, reduces production costs, and results in a smaller overall footprint. After drying in the drying section, the filaments enter the cooling section for cooling, increasing the moisture regain of the filaments. This allows the filaments to fully curl, improving their strength and toughness, resulting in excellent breakage resistance, fiber opening uniformity, and processing stability.

[0035] 3. The spinning machine provided by this invention employs an upper and lower layer winding device with staggered arrangement. This achieves double filaments on a single roller while further preventing filament tangling during winding, ensuring filament quality and making the spinning machine structure more compact and space-saving. Furthermore, in this invention, the upper layer winding machines are driven individually by winding motors housed within the winding machine casing, solving the problem of insufficient space for arranging the upper and lower layer winding machines and enhancing safety.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0050] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0051] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0052] The present invention will be further described in detail below with reference to the embodiments.

[0053] like Figures 1 to 3 As shown, this embodiment provides a spinning roller 7, including: a spinning roller body 71 capable of spinning at least two filaments simultaneously, the spinning roller body 71 having a columnar structure, and the filaments being spirally wound from one end of the spinning roller body 71 to the other end along its axial direction.

[0054] From one end to the other, multiple spiral feeding grooves are spirally arranged on the peripheral wall of the spinning roller body 71. Adjacent spiral feeding grooves are independently arranged for individual feeding. The number of spiral feeding grooves is the same as the number of filaments on each spinning roller 7, and they are arranged in a one-to-one correspondence.

[0055] Specifically, the spiral feeding groove is spiral-shaped and extends from one end of the spinning roller body 71 to the other end along the axial direction of the spinning roller body 71. The path of the spiral feeding groove is the same as the path of the filament. The filament can run on the spinning roller 7 along the path of its corresponding spiral feeding groove, thus avoiding the phenomenon of filament bundling.

[0056] It should be noted that, in one embodiment, the spiral feeding groove can be a part of the structure of the spinning roller body 71, and the spiral feeding groove is directly formed on the spinning roller body 71.

[0057] Alternatively, the spiral feeding groove can be an integral structure added to the spinning roller body 71. For example, a cylindrical cover can be provided on the outer surface of the peripheral wall of the spinning roller body 71, and the spiral feeding groove is provided on the cover. Preferably, the cover is detachably installed on the spinning roller body 71, and a cover with a corresponding number of spiral feeding grooves can be replaced when the spinning roller 7 needs to run different numbers of filaments. By adopting the above solution, a single spinning roller 7 can run different numbers of filaments without the phenomenon of filament bundling, thereby improving the versatility and practicality of the spinning roller 7 and reducing the manufacturing cost of the spinning machine.

[0058] Preferably, the spinning roller 7 provided in this embodiment adopts the first scheme in the above scheme, and the spinning roller body 71 is provided with the spiral feeding groove, which has a simple processing technology and is easier to implement.

[0059] The spinning machine provided in this embodiment can carry multiple filaments on each spinning roller 7, which reduces costs and further improves the production efficiency of the spinning machine. Furthermore, by opening multiple spiral feeding grooves on the outer surface of the spinning roller body 71, the filaments are fed in separate spiral feeding grooves, which effectively avoids the phenomenon of filament tangling that easily occurs when multiple filaments run on the same spinning roller 7. This increases the output while effectively ensuring the quality of the filaments.

[0060] In this embodiment, a detailed description is given using the example of two filaments running on the spinning roller 7:

[0061] Specifically, the spinning roller body 71 spins two filaments simultaneously. The spiral feeding groove includes a first spiral feeding groove 7111 and a second spiral feeding groove 712, each capable of operating independently. The first spiral feeding groove 7111 and the second spiral feeding groove 712 extend spirally from one end of the spinning roller body 71 to the other end. One filament runs along the trajectory of the first spiral feeding groove 7111, and the other filament runs along the trajectory of the second spiral feeding groove 712.

[0062] Preferably, the bottom walls of the first spiral feeding groove 7111 and the second spiral feeding groove 712 are at different vertical distances from the central axis of the spinning roller body 71. This design makes the first spiral feeding groove 7111 and the second spiral feeding groove 712 appear to be at different heights, which further prevents the yarn from sliding from one spiral feeding groove to another, and further reduces the probability of yarn bundling.

[0063] Furthermore, in one embodiment, a spiral boss 711 is provided on the peripheral wall of the spinning roller body 71, extending spirally from one end of the spinning roller body 71 to the other end. The spiral boss 711 is a spirally shaped rib structure protruding from the outer peripheral wall of the spinning roller body 71. A first spiral feeding groove 7111 is formed on the spiral boss 711, and a filament travels along the first spiral feeding groove 7111 of the spiral boss 711.

[0064] Preferably, the groove structure formed between two adjacent spiral bosses 711 and the peripheral wall of the spinning roller body 71 forms the second spiral feeding groove 712. The inner wall surface of two adjacent spiral bosses 711 and the outer wall surface of the spinning roller body 71 located between two adjacent spiral bosses 711 constitute the second spiral feeding groove 712. Another filament travels along the second spiral feeding groove 712 formed between the two spiral bosses 711.

[0065] Since the spiral boss 711 protrudes from the outer peripheral wall of the spinning roller body 71, the height of the first spiral feeding groove 7111 from the central axis of the spinning roller body 71 is higher than the height of the second spiral feeding groove 712. The two filaments run in two feeding grooves at different heights, making it less likely for the filaments to clump together.

[0066] Preferably, such as Figure 3 As shown, the spiral boss 711 includes a top wall and two side walls, and the first spiral thread feeding groove 7111 is a curved groove formed on the top wall of the spiral boss 711. The first spiral thread feeding groove 7111 is a curved groove formed by an inward recess of the top wall of the spiral boss 711. By setting the first spiral thread feeding groove 7111 as a curved groove, compared with setting it as a straight groove, it is possible to effectively avoid phenomena such as wire scraping and stagnation when the wire travels in the first spiral thread feeding groove 7111, so that the wire can travel more smoothly in the first spiral thread feeding groove 7111.

[0067] Combination Figure 1 , Figure 4 , Figure 5 As shown, this embodiment also provides a spinning device having the above-mentioned spinning roller 7. The spinning device includes a plurality of the spinning rollers 7 and a processing roller 8 with a diameter larger than the spinning rollers 7. The processing roller 8 and each spinning roller 7 correspond one-to-one to form multiple sets of roller pairs. At least two filaments alternately pass through the spinning rollers 7 and the processing roller 8. Each filament is spirally wound from one end of the roller pair to the other end along its corresponding spiral feeding groove.

[0068] Preferably, the number of spinning rollers 7 is 4-8. More preferably, the number of spinning rollers 7 is 4, with two filaments running on each spinning roller 7, for a total of eight filaments. This achieves continuous spinning production with 4 rollers and 8 filaments, improving spinning efficiency while reducing the number of spinning rollers 7, lowering costs and space requirements. Furthermore, the spiral feeding groove prevents filament tangling, effectively ensuring filament quality.

[0069] Furthermore, along the direction of the filament's travel, the processing roller 8 includes a drying section 81 and a cooling section 82 sequentially disposed at its end. The drying section 81 is provided with a heating structure, and the cooling section 82 is provided with a cooling structure. When the filament passes the end of the processing roller 8, the heating structure dries the filament entering the drying section 81, and the cooling structure cools the filament entering the cooling section 82 after drying.

[0070] Furthermore, as the filaments pass through the drying section 81 and the cooling section 82 sequentially, the drying section 81 is heated by the heating structure, thereby heating the filaments wound on the drying section 81 and achieving drying. The cooling section 82 is cooled by the cooling structure, thereby cooling the filaments wound on the cooling section 82. After being dried in the drying section 81, the filaments enter the cooling section 82 for cooling, which increases the moisture regain of the filaments, allowing them to fully curl, improving their strength and toughness, and giving them excellent resistance to breakage, uniform fiber opening, and processing stability.

[0071] Furthermore, the drying section 81 and cooling section 82 of the processing roller 8 are made of metal thermally conductive material. The heating structure includes a heat-conducting pipe, which is coiled on the inner peripheral wall of the processing roller 8 located in the drying section 81. The filaments entering the drying section 81 are dried by injecting a heating medium into the heat-conducting pipe.

[0072] The heating medium can be hot water, hot steam, or heat transfer oil. One end of the heat transfer pipe is provided with a heating medium inlet 811, and the other end is provided with a heating medium return port 812. The heating medium inlet 811 is located above the drying section 81 of the processing roller 8, and the heating medium return port 812 is located below the drying section 81 of the processing roller 8. The coordination of the upper and lower height positions of the heating medium inlet 811 and the heating medium return port 812 facilitates the injection and return of the heating medium, thereby improving the drying effect of the yarn.

[0073] The heating medium inlet 811 at one end of the heat pipe is connected to a heating medium inlet pipe, through which heating medium is injected into the heat pipe. The heating medium inlet 811 at the other end of the heat pipe is connected to a medium return pipe, through which the heating medium in the heat pipe is discharged and returned.

[0074] Furthermore, the cooling structure includes a cooling pipe, which is coiled on the inner peripheral wall of the processing roller 8 located in the cooling section 82. The filaments entering the cooling section 82 are cooled by injecting a cooling medium into the cooling pipe.

[0075] The cooling medium can be cold water, cold steam, or cold brine, etc. One end of the cooling pipe is provided with a cooling medium inlet 821, and the other end is provided with a cooling medium return port 822. The cooling medium inlet 821 is located at the upper part of the cooling section 82 of the processing roller 8, and the cooling medium return port 822 is located at the lower part of the cooling section 82 of the processing roller 8. The coordination of the upper and lower height positions of the cooling medium inlet 821 and the cooling medium return port 822 facilitates the injection and return of the cooling medium, thereby improving the cooling effect of the yarn.

[0076] The cooling medium inlet 821 at one end of the cooling pipe is connected to a cooling medium inlet pipe, through which cooling medium is injected into the cooling pipe. The cooling medium return port 822 at the other end of the cooling pipe is connected to a cooling medium return pipe, through which the cooling medium in the cooling pipe is discharged and returned.

[0077] The spinning machine provided in this embodiment has a drying section 81 for drying the filament and a cooling section 82 for cooling the filament at the end of the processing roller 8. The filament can be dried and cooled at the same time as it is drawn and spun on the spinning roller 7 and the processing roller 8. There is no need to set up a separate drying roller and cooling roller, which simplifies the structure of the entire spinning machine, reduces production costs, and makes the overall space occupied by the spinning machine smaller.

[0078] Furthermore, in this embodiment, the end of the processing roller 8 is tapered, so that the filament can be retracted and shaped when passing through the tapered portion of the processing roller 8.

[0079] The end of the processing roller 8 is narrowed to form a narrowed section. Preferably, the length of the narrowed section is equal to the sum of the lengths of the drying section 81 and the cooling section 82. The outer peripheral wall of the processing roller 8 located in the drying section 81 and the cooling section 82 is narrowed. This allows the filament to be retracted and shaped during the drying and cooling process at the end of the processing roller 8, replacing the fiber crimping and shaping process, thus achieving a fiber shaping effect and further simplifying the production process.

[0080] Specifically, the reduced diameter section of the processing roller 8 can have the following structural options:

[0081] Option 1: As Figure 6 As shown, the diameter reduction section of the processing roller 8 can be set in a stepped segmented manner with each segment gradually decreasing in diameter.

[0082] The second option: Figure 4 , Figure 7 As shown, the end of the processing roller 8 can be designed to gradually reduce its outer diameter to form a frustum shape.

[0083] The third option: (e.g.) Figure 8 As shown, the end of the processing roller 8 is configured with a combination of stepped segmented and frustum-shaped diameter reduction methods.

[0084] Preferably, in this embodiment, the end of the processing roller 8 is designed with a gradually decreasing outer diameter to form a frustum shape, which is the second scheme described above.

[0085] More preferably, the processing roller 8, which has a frustum-shaped end, has a cone angle of α, where 4°≤α≤10°. The angle between the two generatrices of the axial section of the frustum-shaped reduced-diameter section is the cone angle. By changing the outer surface of the processing roller 8 to a 2°-5° (i.e., α / 2) tip surface 8a, the draft of the filament is increased, further ensuring the quality of the filament.

[0086] This embodiment also provides a spinning machine having the above-mentioned spinning device. The spinning machine further includes a winding device. The filaments processed by the spinning device are guided by the filament guiding mechanism 9 to the winding device and wound into a cylinder.

[0087] Furthermore, such as Figure 1 and Figure 5 As shown, the winding device includes an upper winding machine 10 and a lower winding machine 11, and the upper winding machine 10 and the lower winding machine 11 are multi-spindle winding machines.

[0088] The positions of the upper winding machine 10 and the lower winding machine 11 can be set in a one-to-one correspondence between the upper and lower layers; or the upper winding machine 10 and the lower winding machine 11 can be arranged in a staggered manner between the upper and lower layers, and the number of the upper winding machine 10 and the lower winding machine 11 can be freely combined.

[0089] Preferably, the total number of winding machines is 8-16, with the upper winding machine 10 and the lower winding machine 11 arranged in a staggered manner. In this embodiment, the winding device adopts a staggered arrangement between the upper winding machine 10 and the lower winding machine 11, which not only achieves double filaments on one roller, but also further avoids the phenomenon of filaments tangling during the winding process, thus ensuring the quality of the filaments.

[0090] More preferably, the total number of winding machines is 8, with 4 upper-layer winding machines 10 and 4 lower-layer winding machines 11, arranged in a staggered manner. The spinning machine provided in this embodiment uses an upper-layer winding machine 10 and a lower-layer winding machine 11 arranged in a staggered manner between the upper and lower layers. This achieves double filaments on a single roller while further preventing filament tangling during winding, ensuring filament quality, and making the spinning machine structure more compact and space-saving.

[0091] Furthermore, the upper winding machine 10 includes a housing and a winding head 102 and a winding motor 101 disposed within the housing, and the upper winding head 102 is driven by the winding motor 101 one by one.

[0092] Furthermore, the winding head 102 also includes a winding drum for winding the filament into a cylinder. A first toothed pulley 1011 is provided on the output shaft of the winding motor 101, and a second toothed pulley 1021 is provided on the winding shaft of the winding drum. The first toothed pulley 1011 and the second toothed pulley 1021 are connected by a synchronous gear belt 103.

[0093] In this embodiment, the upper winding machine 10 is driven by winding motors 101 set in the winding machine housing, which solves the problem of insufficient space for the upper and lower winding machines. By using electronic winding or self-made single-power friction winding, the structure of the spinning machine is more compact, the winding effect is better, and the safety is higher because the winding motors 101 are set in the housing.

[0094] Furthermore, in this embodiment, the lower winding machine 11 is driven by the same power box 12, and the output end of the power box 12 is connected to a transverse rod 121. The lower multi-spindle winding machines are driven by the same transverse rod 121.

[0095] Preferably, the traverse rod 121 includes an upper traverse rod and a lower traverse rod, which are constantly connected by a connecting rod 122. The upper traverse rod drives the processing roller 8, and the lower traverse rod drives the lower winding machine 11. Power is simultaneously provided to the lower multi-spindle winding machine and the processing roller 8 through the same power box 12, making full use of the power of the power box 12 and simplifying the structure of the spinning machine.

[0096] The spinning machine provided in this embodiment also includes a forming device and a feeding device. The feeding device provides spinning solution to the forming device. The spinning solution is reacted in the coagulation bath or acid bath of the forming device and coagulated to form filaments. The formed filaments are guided by the guide wheel 5 to the spinning device for stretching, drying, cooling and other steps.

[0097] Specifically, the feeding device includes a metering pump 1, a filter 2, and multiple spinnerets. The feeding device includes a feeding pipe connected to each spinneret and a metering pump 1, with one end of the feeding pipe connected to the metering pump 1 and the other end connected to each spinneret. A filter 2 is installed on the feeding pipe, which effectively filters impurities in the spinning solution, further ensuring the quality of the filament.

[0098] Preferably, the feeding device further includes a feeding motor, which includes a long drive shaft with a certain extension length. Multiple metering pumps 1 are respectively connected to the long drive shaft, and the long drive shaft of the feeding motor can drive multiple metering pumps 1 simultaneously. All metering pumps 1 are driven by a single drive shaft to ensure consistent rotation speed and improve the uniformity of filament quality.

[0099] Furthermore, the forming device includes a coagulation bath / acid box 3 and a glass tube 4. The spinning solution is pressed through the spinneret orifice. The fine stream of spinning solution is formed into filaments in the coagulation bath of the coagulation bath 3, or the fine stream of spinning solution reacts with the acid bath of the acid box 3 to form filaments. After the filaments are reacted in the coagulation bath or acid bath, they enter the glass tube 4. After being further solidified in the glass tube 4, the filaments pass through the guide roller 5, the scraper 6, the spinning roller 7, and the processing roller in sequence, and enter the post-processing process. After processing, drying, and cooling, they are wound into a cylinder.

[0100] In the above scheme, the same coagulation bath / acid box 3 can have two outlets, and each outlet is equipped with a glass tube 4, which can realize the simultaneous spinning of two spindles by one coagulation bath / acid box 3.

[0101] Alternatively, the arrangement and size of the coagulation bath / acid box 3 can be optimized so that eight coagulation bath / acid box 3s can be placed in the original four positions, and eight glass tubes 4 can be connected so that eight filaments can be spun simultaneously.

[0102] In this embodiment, the provided coagulation bath box / acid box 3 can be used interchangeably with one box for dual output and multiple boxes for multiple output, allowing users to flexibly change the number of threads spun and improve the user experience.

[0103] Preferably, in this example, there are 8 coagulation bath boxes / acid boxes 3, each coagulation bath box / acid box 3 has an outlet, and each outlet is connected to a glass tube 4.

[0104] Preferably, the length of the glass tube 4 in this example is 800-990mm or 1010-1200mm, which further ensures that the filament has sufficient length space inside the glass tube 4 to ensure that the filament can be fully solidified and formed in the glass tube 4.

[0105] Furthermore, in this embodiment, a filament separating rod is provided on the filament between the output end of the glass tube 4 and the spinning roller 7. The filament separating rod is a filament separating device that can ensure that the spinning roller 7 has multiple filaments on one roller, effectively avoiding the phenomenon of two filaments sticking together before entering the spinning device.

[0106] The spinning machine provided in this embodiment is a continuous spinning machine. Through equipment improvements, it achieves single-output, double-output, and multi-output configurations from the coagulation bath / acid box 3, as well as double-filament, multi-filament, and multi-filament configurations on a single roller. This solves the problems of insufficient spindle space, low spinning speed, inability to expand production capacity, and failure to meet users' needs for increased production and efficiency in continuous spinning machines. By setting multiple spiral feeding grooves on the spinning roller 7, the problem of yarn tangling that easily occurs when two or more filaments are running on the spinning roller 7 in existing continuous spinning machines is solved. This not only affects the normal operation of other filaments and results in poor stability, but also causes major quality problems such as double-strand yarns.

[0107] The continuous spinning machine provided in this embodiment is suitable for preparing various chemical fibers, including but not limited to viscose rayon, acrylic filament, polyester filament, or acrylonitrile-based carbon fiber precursor. Since viscose rayon has good spinnability, the advantages of using the spinning machine provided in this embodiment are more pronounced, significantly improving the production efficiency of viscose rayon while ensuring the quality of the resulting viscose fiber. Therefore, the spinning machine provided in this embodiment is preferred for preparing viscose rayon.

[0108] The implementation schemes in the above embodiments can be further combined or replaced, and the embodiments are merely descriptions of preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention. Various changes and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the design concept of the present invention shall fall within the protection scope of the present invention.
