[0002] Chemical fiber is a kind of fiber material made of high molecular compound, which is widely used in many fields such as textile, industry, medical treatment and high-performance composite material manufacturing due to its advantages of high strength, light weight, corrosion resistance and mass production. In the production process of chemical fiber, the continuous yarn produced after spinning, drawing and drying processes needs to be wound into a reel for subsequent transportation, storage and reprocessing.

[0003] At present, the conventional chemical fiber yarn collecting device generally comprises a rotating cylinder for winding yarn and a yarn guide mechanism for guiding yarn, wherein the yarn guide mechanism realizes the reciprocating movement of yarn by simple mechanical structure to arrange the yarn evenly on the surface of the cylinder. Generally, the yarn guide mechanism adopts fixed track, sliding guide rod or manual assistance to control the movement of yarn.

[0004] However, due to the simple design of the yarn guide structure, the guiding movement of yarn is unstable and the control precision is low, which often causes uneven arrangement of yarn, overlapping or cross-accumulation of adjacent yarn in actual production, especially in high-speed continuous production environment, which directly leads to the decline of yarn collecting quality and even affects the subsequent processing efficiency and quality stability of chemical fiber products.

As shown in Figure 8 It is a schematic diagram of the overall structure of the yarn collecting device for chemical fiber production according to an embodiment of the present application from another perspective. As shown in Figures 1-4 the present application provides a yarn collecting device for chemical fiber production, which comprises a support frame 100, a yarn collecting cylinder assembly 300, a first driving assembly 500 and a second driving assembly 600, a sliding seat 700 and a moving rod 800.

[0038] The yarn collecting cylinder assembly 300 is rotatably installed at the front end of the support frame 100 and is driven to rotate by the first driving assembly 500 for collecting the yarn; the lead screw 610 is installed between the front and rear inner plates of the support frame 100, the sliding seat 700 is installed on the lead screw 610, and the lead screw 610 is driven to rotate by the second driving assembly 600 to drive the sliding seat 700 to reciprocate along the lead screw 610 in the axial direction; one end of the moving rod 800 is connected with the sliding seat 700, the other end of the moving rod 800 is movably inserted through the front plate of the support frame 100 and can move synchronously with the sliding seat 700; the moving rod 800 is provided with the yarn guide ring 810 and the guide wheel 820 at the end extending out of the support frame 100, and the yarn guide ring 810 and the guide wheel 820 are used for guiding the yarn and moving synchronously with the moving rod 800 to realize uniform arrangement of the yarn on the yarn collecting cylinder assembly 300.

[0039] The yarn collecting device for chemical fiber production provided by the embodiment of the application is rotatably installed with the yarn collecting cylinder assembly 300 at the front end of the support frame 100 and is driven to stably rotate by the first driving assembly 500, so that the yarn can be more stably wound on the yarn collecting cylinder assembly 300, the vibration or shaking of the yarn during winding is reduced, the yarn is more neatly arranged, and the uniformity of product winding and the overall appearance quality are improved. The first driving assembly 500 is used to control the yarn collecting and winding process, which helps to keep the rotating speed of the yarn collecting cylinder assembly 300 stable during operation, thereby creating favorable conditions for uniform winding of the fiber yarn and reducing the problem of disordered arrangement of the yarn due to unstable rotating speed of the cylinder.

[0040] Meanwhile, the lead screw 610 is installed in the support frame 100, the sliding seat 700 is arranged on the lead screw 610, the lead screw 610 is driven to rotate by the second driving assembly 600, and the sliding seat 700 is driven to stably reciprocate along the lead screw in the axial direction, so that the smooth movement of the sliding seat 700 can drive the moving rod 800 to synchronously and smoothly move forward and backward, the linkage structure of the lead screw 610, the sliding seat 700 and the moving rod 800 improves the mechanical stability of the yarn guide ring 810 and the guide wheel 820 during the movement of the moving rod 800, the movement position of the sliding seat 700 can be more accurately controlled through this structure, the movement position of the sliding seat 700 can be more accurately controlled through this structure, and the stability and positioning accuracy of the yarn guiding action are improved, which can effectively reduce the swing or deviation in the traditional yarn guiding mode.

[0041] In addition, the embodiment of the present application is provided with a guide wire ring 810 and a guide wheel 820 at one end of the moving rod 800 extending out of the support frame 100, and the guide wire ring 810 and the guide wheel 820 move synchronously with the moving rod 800 to form a stable and reliable wire guide structure. The guide wire ring 810 can keep the position of the wire entering the device relatively stable, and the guide wheel 820 effectively reduces the friction between the wire and the guide component. Through this structural design, the wire can pass through the guide wire ring 810 and the guide wheel 820 more smoothly, so that the wire can be more accurately guided to the wire collecting cylinder assembly 300, thereby improving the phenomenon of uneven or cross-stacking of the wire, and significantly improving the collection quality and production efficiency of the wire. Moreover, the arrangement of the guide wire ring 810 and the guide wheel 820 enables the wire to pass through two continuous positioning links during the conveying process, and this two-section positioning structure helps to accurately control the conveying path of the wire.

[0042] In some embodiments, as shown in Figures 1-4 The bottom of the support frame 100 is provided with universal casters 101 and adjustable legs 102 for moving and positioning the device, and the rear side of the support frame 100 is provided with a detachable maintenance plate 103.

[0043] In this embodiment, the universal casters 101 are installed at the bottom of the support frame 100, so that the entire wire collecting device can be moved more easily in the production site, facilitating arrangement according to different production needs. Moreover, through this structural design, the device can better connect with other processes in the production line, improving the on-site adaptability of the device and helping to improve the flexibility and efficiency of the overall use of the device.

[0044] Meanwhile, based on the arrangement of the universal casters 101, the adjustable legs 102 are additionally provided at the bottom of the support frame 100. After the device is moved to the designated position, the operator can adjust the adjustable legs 102 to stabilize the device, lock the position, and fine-tune the height. This structure can effectively prevent the device from slipping or vibrating during operation.

[0045] In addition, the detachable maintenance plate 103 is arranged at the rear side of the support frame 100, which facilitates the maintenance and repair of the first drive assembly 500, the second drive assembly 600, and other transmission structures inside the device. The operator does not need to disassemble the entire frame, but only needs to open the maintenance plate 103 to easily access the key components inside the device. This structure can simplify the complexity of daily maintenance of the device, save maintenance time, help to prolong the service life of the device, and effectively reduce the production loss caused by maintenance downtime.

[0046] In some embodiments, the wire collecting cylinder assembly 300 includes a wire collecting cylinder 301, a connecting flange 302, and a transmission shaft 303, as shown inFigure 1 and Figure 3 As shown in Figure 2 and Figure 5 As shown in FIG. 3, the connecting flange 302 is fixedly installed on the mounting plate at the front end of the support frame 100, and the yarn collecting cylinder 301 is a hollow cylindrical structure. The outer circumferential surface of the rear end of the yarn collecting cylinder 301 is rotatably installed on the connecting flange 302 through a bearing assembly. The middle part of the rear end of the yarn collecting cylinder 301 is connected with a transmission shaft 303, which is horizontally arranged and penetrates through the support frame 100 and is connected with the first driving assembly 500 in the support frame 100.

[0047] In the above embodiment, the connecting flange 302 is fixedly installed on the mounting plate at the front end of the support frame 100, and the outer circumferential surface of the rear end of the yarn collecting cylinder 301 is rotatably installed on the connecting flange 302 through a bearing assembly. Through this installation mode, the frictional resistance in the rotation process of the yarn collecting cylinder 301 can be effectively reduced, which helps to realize a more stable rotation state and reduce the vibration and shaking phenomenon in the rotation process. This structure has a positive effect on improving the arrangement uniformity and winding stability of the yarn during winding.

[0048] Meanwhile, the middle part of the rear end of the yarn collecting cylinder 301 is connected with the transmission shaft 303 which is horizontally arranged and penetrates through the support frame 100 and is connected with the first driving assembly 500 in the support frame 100. This transmission mode helps to reduce the loss or delay of power in the transmission process, thereby improving the transmission efficiency of the power and making the rotation of the yarn collecting cylinder 301 better maintain synchronization and a stable state, and further improving the flatness and consistency of the yarn during winding, thereby effectively improving the production efficiency of the device.

[0049] In addition, a plurality of arc-shaped plates 304 extending in the axial direction and uniformly distributed are arranged on the outer circumferential surface of the yarn collecting cylinder 301, so that a spacing space is formed between adjacent arc-shaped plates 304. The design of this spacing space can make the yarn more conveniently taken off from the yarn collecting cylinder 301 after winding, which helps to reduce the adhesion or too tight winding between the yarn and the yarn collecting cylinder 301. In addition, these spacing spaces can also play a certain heat dissipation role when the yarn collecting cylinder 301 rotates, so that the heat accumulated inside the wound yarn is more easily dissipated, which is beneficial to the stable winding of the yarn and the maintenance of the yarn quality, thereby improving the efficiency of the whole yarn collecting process and the product quality.

[0050] In some embodiments, as shown in Figure 2 and Figure 4 The first driving assembly 500 includes a first motor 501, a first pulley 502, a second pulley 503, and a belt I 504.

[0051] The first motor 501 is fixedly installed at the inner bottom of the support frame 100, the first belt pulley 502 is installed on the output shaft of the first motor 501, the second belt pulley 503 is installed at the rear end of the transmission shaft 303, and the belt I 504 is wound between the first belt pulley 502 and the second belt pulley 503, for transmitting the power of the first motor 501 to the transmission shaft 303 to drive the rotation of the take-up drum 301.

[0052] The first driving assembly 500 in the embodiment adopts the first motor 501 as a power source, and transmits power by the belt I 504 between the first belt pulley 502 and the second belt pulley 503. This belt transmission mode can effectively reduce the impact and vibration in the transmission process, and the power output is relatively soft, so that the rotation state of the take-up drum 301 is more stable, thereby effectively reducing the irregular arrangement of the silk thread caused by instantaneous impact during winding, and helping to improve the uniformity of silk thread winding.

[0053] In terms of structural layout, the first motor 501 is fixedly arranged at the inner bottom of the support frame 100. Since the first motor 501 is installed at a lower position, the overall gravity center of the device can be lowered, so that the stability of the device during operation can be better improved. In addition, since the first motor 501 is installed at the inner bottom of the frame 100, the vibration generated during operation can be better absorbed and dispersed through the frame structure, thereby effectively reducing the overall vibration amplitude of the device during operation, helping to prolong the service life of the device and improve the stability during silk thread winding.

[0054] Meanwhile, the first belt pulley 502 and the second belt pulley 503 are connected and transmitted by the belt I 504. This transmission structure has good buffering performance, and flexible transmission ratio adjustment can be realized by replacing belt pulleys with different diameters to adapt to different varieties or specifications of chemical fiber winding processes. This structural design reduces the complexity and time consumption of device adjustment on the production line, and helps to improve the flexibility and production efficiency of the device.

[0055] In some embodiments, as shown in Figure 3 and Figure 4 The second driving assembly 600 includes a second motor 601, a third belt pulley 603, a fourth belt pulley 604, and a belt II 602.

[0056] The second motor 601 is fixedly installed at the upper side of the support frame 100, the third belt pulley 603 is installed on the output shaft of the second motor 601, the fourth belt pulley 604 is installed at the rear end of the lead screw 610, the belt II 602 is wound between the third belt pulley 603 and the fourth belt pulley 604, for transmitting the power of the second motor 601 to the lead screw 610 to drive its rotation; and the sliding seat 700 is threadedly connected to the lead screw 610.

[0057] In the above embodiment, the second driving assembly 600 includes the second motor 601, and a transmission structure is formed by the third belt pulley 603, the fourth belt pulley 604, and the belt II 602. By using this belt transmission mode, the power generated by the second motor 601 can be transmitted to the lead screw 610 more smoothly. The belt transmission structure helps to reduce the vibration and noise during the operation of the device, making the power transmission more stable and soft, so that the rotation of the lead screw 610 can be more smooth, effectively improving the precision and stability of the sliding seat 700 during movement.

[0058] The second motor 601 is installed on the upper inside of the support frame 100. This layout makes the installation position of the second motor 601 relatively high. This position design can reasonably utilize the space inside the frame, and is convenient for heat dissipation of the second motor 601, reducing the risk of excessive temperature rise during operation of the motor. In addition, this higher position layout helps to reduce interference with other components, and facilitates the operator to quickly access the second motor 601 during maintenance or inspection, thereby improving the convenience and efficiency of device maintenance.

[0059] In addition, the lead screw 610 and the sliding seat 700 are connected by threads. Through this structure, the rotational motion of the second motor 601 can be accurately converted into the linear reciprocating motion of the sliding seat 700. This threaded connection mode has high transmission efficiency and accurate position control, and can realize fine displacement adjustment of the sliding seat 700. Therefore, the moving rod 800 driven by the sliding seat 700 has good stability during movement, effectively reducing the possibility of disorder or crossing during the arrangement of the silk thread, which plays a positive role in improving the quality of silk thread collection and the stability of the production process.

[0060] In some embodiments, as shown in Figure 4 and Figure 6 The connecting plate 710 is fixedly connected above the sliding seat 700, and the end of the connecting plate 710 is provided with a connecting sleeve 720. The connecting sleeve 720 is fixedly connected with one end of the moving rod 800 inside the support frame 100. The bottom end of the sliding seat 700 is provided with a sliding block, and the support frame 100 is internally provided with a slide rail 730 located directly below the sliding seat 700. The slide rail 730 is fixedly installed on the mounting bracket inside the support frame 100, and is provided with a slide way for limiting the movement displacement of the sliding block at the bottom of the sliding seat 700.

[0061] In this embodiment, the sliding seat 700 is fixedly connected with a connecting plate 710, and the end of the connecting plate 710 is provided with a connecting sleeve 720 which is fixedly sleeved with one end of the moving rod 800. This sleeve connection structure is relatively stable, and can better transmit the linear motion of the sliding seat 700 to the moving rod 800, effectively reducing the possibility of loosening or misalignment of the moving rod 800 during reciprocating motion, thereby helping to improve the accuracy of the overall motion trajectory of the guide wire structure.

[0062] In addition, the bottom end of the sliding seat 700 is provided with a sliding block, and the inside of the support frame 100 is provided with a sliding rail 730 located directly below the sliding seat 700. The sliding rail 730 is fixedly installed on the mounting bracket inside the support frame 100, and forms a cooperation relationship between the sliding rail 730 and the sliding block at the bottom end of the sliding seat 700, thereby providing a stable linear movement track for the sliding seat 700. When the lead screw 610 drives the sliding seat 700 to move, the sliding block can move relatively smoothly along the preset path of the sliding rail 730. This structural design effectively reduces the risk of deviation or inclination of the sliding seat 700, and can better avoid the shaking and jamming phenomenon during movement, thereby further improving the stability of the movement of the sliding seat 700.

[0063] Furthermore, the sliding rail 730 is provided with a sliding groove which can constrain the position of the sliding block at the bottom of the sliding seat 700 to limit the movement path of the sliding seat 700. Through the guiding effect of the sliding groove, the sliding seat 700 can accurately maintain a linear trajectory during reciprocating motion, thereby reducing the problem of lateral displacement caused by external interference or vibration. This guiding structure not only helps to improve the stability of the movement trajectory of the sliding seat 700 and the moving rod 800, but also positively affects the positioning accuracy of the guide wire ring 810 and the guide wheel 820, thereby improving the neatness and uniformity of the wire during winding on the yarn collecting cylinder assembly 300.

[0064] In some embodiments, as shown in Figure 1 and Figure 3 , the moving rod 800 is located above the side of the yarn collecting cylinder assembly 300, as shown in Figure 3 and Figure 7 , the guide wheel 820 is a rotating wheel with a bearing rotatably installed at the front end of the moving rod 800. The front end of the moving rod 800 is fixedly provided with a connecting block 801 behind the guide wheel 820, the connecting block 801 extends outwardly and is fixedly connected with the guide wire ring 810. The guide wire ring 810 is an integrally formed annular structure, and is fixedly arranged on the front side of the connecting block 801. The guide wire ring 810 is provided with a wire inlet hole 811, and the axis of the guide wire ring 810 is perpendicular to the axis of the guide wheel 820. The guide wire ring 810 can contact the wire through the wire inlet hole 811 and guide the wire to be transported in the direction of the yarn collecting cylinder 301 after the guide wheel 820.

[0065] In the above embodiment, the moving rod 800 is arranged above the side of the yarn collecting cylinder assembly 300, and a guide wheel 820 with a bearing is arranged at the front end of the moving rod 800. With this structure, the conveying path of the yarn is conducive to improving the smoothness and stability of the yarn conveying and winding on the yarn collecting cylinder assembly 300. The guide wheel 820 can effectively reduce the frictional resistance of the yarn when it passes through the guide wheel 820, reduce the wear and tear of the yarn surface and the jumping phenomenon, make the conveying process of the yarn more stable, and further improve the stability and overall quality of the yarn winding.

[0066] In addition, an outwardly extending connecting block 801 is fixedly arranged on the front end of the moving rod 800, and the connecting block 801 is connected with the yarn guide ring 810, so that the position of the yarn guide ring 810 is more stable. The yarn guide ring 810 is an integral annular structure, which is strong in rigidity and simple and reliable in structure. This structure can accurately determine the position of the yarn entering the yarn guide ring 810, effectively reduce the possibility of position deviation of the yarn after entering, and reduce the disorder or crossing of the yarn, thereby improving the winding quality of the yarn.

[0067] In the structure design of the yarn guide ring 810, the yarn guide ring 810 is provided with a yarn inlet hole 811, and the axis of the yarn inlet hole 811 is perpendicular to the axis of the guide wheel 820. Such a structure design enables the yarn to pass through two consecutive positioning links in the conveying process: first, the yarn passes through the yarn inlet hole 811 of the yarn guide ring 810 for preliminary positioning, and then the yarn is further guided stably through the guide wheel 820. This two-stage positioning structure helps to accurately control the conveying path of the yarn, improves the neatness and stability of the yarn arrangement, and effectively improves the winding effect of the yarn on the surface of the yarn collecting cylinder 301, thereby improving the production efficiency and product quality.

[0068] In some embodiments, as shown in Figs. 1-3, Figure 1 and Figure 8 The yarn collecting device for chemical fiber production of the present application further comprises an electric control box 200 arranged above the side panel of the support frame 100. The electric control box 200 is electrically connected with the first driving assembly 500 and the second driving assembly 600. A control panel is arranged on the front side of the electric control box 200 for controlling the first driving assembly 500 and the second driving assembly 600.

[0069] In this embodiment, the electric control box 200 is arranged above the side panel of the support frame 100, close to the usual work area of the operator. This structure has a reasonable layout position, which is convenient for the operator to observe and operate. In addition, the space of the side panel of the support frame 100 is relatively sufficient, which is conducive to the firm fixation of the electric control box 200.

[0070] In addition, the control panel is arranged on the front side of the electric control box 200, and in actual application, the operator can directly adjust the start-stop, rotating speed and other parameters of the driving motor through the buttons or knobs on the control panel. The control operation through the control panel of the electric control box 200 helps the operator to flexibly control the running state of the device according to different production conditions. Especially in the chemical fiber production environment which needs to frequently convert the specifications and speed, the intuitive and convenient control mode can obviously reduce the error of manual regulation, and further enhance the practicability and high-quality operation level of the device.

[0071] In some embodiments, the support frame 100 is a rectangular frame structure composed of metal profiles, which is assembled by welding. The support frame 100 is internally provided with a connecting bracket for mounting the first driving assembly 500 and the second driving assembly 600.

[0072] In this embodiment, the support frame 100 is a rectangular frame structure made of metal profiles, and is assembled into a whole by welding. This welded structure has high rigidity and anti-deformation ability, which is beneficial to reduce the mechanical vibration and structural deformation problems generated during long-time operation of the device, and helps to reduce the possibility of structural loosening of the device due to external impact or self-operation vibration, thereby laying a good foundation for stable and efficient operation of the device.

[0073] In addition, the connecting bracket for mounting the first driving assembly 500 and the second driving assembly 600 is arranged inside the frame 100, which not only optimizes the utilization efficiency of space and makes the device more compact, but also provides a modular installation method for the driving assembly which is convenient for maintenance and replacement. This layout form is beneficial to the maintenance and debugging on site, and further enhances the adaptability and maintenance convenience of the device in different factory environments.

[0074] The use process of the yarn collecting device provided by the embodiment of the present application is as follows:

[0075] In actual use of the yarn collecting device of the embodiment, first, the operator can move the device to the position required by the chemical fiber production line by using the universal casters 101 at the bottom. After adjustment, the device is relatively stably fixed on the production line by rotating the adjustable supporting legs 102 at the bottom. Next, the yarns after spinning, drafting and drying treatment are sequentially threaded through the guide ring 810 and the guide wheel 820 mounted at the front end of the moving rod 800, and are guided to the surface of the yarn collecting drum 301, so that the yarns are fixed on the yarn collecting drum 301.

[0076] Then, the first driving assembly 500 and the second driving assembly 600 are started respectively through the control panel on the electric control box 200, wherein the first driving assembly 500 drives the spinning drum 301 to rotate, and the device enters the spinning state. At the same time, the second driving assembly 600 drives the screw rod 610 to rotate, and drives the sliding seat 700 to make relatively slow and stable reciprocating motion along the axial direction of the screw rod 610, so as to synchronize the movement of the moving rod 800. At this time, the guide wire ring 810 and the guide wheel 820 can guide the yarn to be arranged uniformly on the surface of the spinning drum 301 in rotation, and the yarn winding process is relatively smooth.

[0077] When the yarn is wound to a predetermined amount or meets the process requirements, the operator stops the operation of the first driving assembly 500 and the second driving assembly 600 through the control panel of the electric control box 200. After stopping the operation of the device, the operator takes off the wound yarn roll from the spinning drum 301, so as to perform the next spinning operation. The spinning device of the embodiment has reasonable overall structure design, and the components cooperate tacitly, which is helpful to the stability and uniformity of the yarn winding, thereby effectively improving the quality and production efficiency of the chemical fiber product.

[0078] In actual application, the spinning device of the embodiment is particularly suitable for the production field of chemical fibers. In the production process of chemical fibers, the yarn treated through spinning, drawing, drying and other links usually needs to be wound and collected for subsequent processing or packaging and transportation. However, the chemical fiber usually has the characteristics of being long, soft, slippery and requiring high uniformity of winding, so the spinning device must have high running stability and yarn guiding accuracy. The embodiment can effectively adapt to the characteristics and requirements of the production of chemical fibers through the specially optimized structure design, such as the stable driving mechanism, the accurate yarn guiding structure and the arc-shaped plate design facilitating the taking off of the yarn, so that the device is more practical and targeted in actual production.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some or all of the technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
