Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wet spinning technology, and in particular relates to a winding device for a wet spinning machine. Background Technology
[0002] Wet spinning is a process in which a polymer solution is extruded through a spinneret and then fed into a coagulation bath to form fibers. This spinning method is commonly used to prepare regenerated cellulose fibers (such as viscose fibers), polyacrylonitrile fibers (PAN, used to prepare carbon fiber precursors), and other polymer materials that require solution spinning to form. In wet spinning, the spinning solution is first extruded through a spinneret and enters a coagulation bath containing a coagulant. The solvent gradually diffuses out in the coagulation bath, allowing the fibers to solidify and form. During wet spinning, the fibers typically retain a certain amount of moisture when they emerge from the coagulation bath. If this moisture is not controlled and dried in time, adhesion will occur during the winding process, causing fiber accumulation. This problem is particularly evident in current wet spinning winding mechanisms. Due to the lack of a translation mechanism in the winding devices of related technologies, the fibers are wound in a fixed position, leading to uneven winding and adhesion between layers. This not only hinders fiber storage and quality maintenance but also obstructs the subsequent unwinding operation, increasing process difficulty and time costs. Summary of the Invention
[0003] In view of this, the present invention aims to at least partially solve one of the related technical problems.
[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0005] A winding device for a wet spinning machine includes a transverse drive mechanism, a roll drive mechanism, a transverse movement mechanism, a roll mechanism, a guide structure, a transverse movement rod, and a guide wheel;
[0006] One end of the transverse rod is connected to the guide wheel via a bearing, and the other end of the transverse rod is connected to the transverse mechanism. The output end of the transverse drive mechanism is connected to the transverse mechanism. The transverse rod slides in cooperation with the housing of the wet spinning machine through the guide structure.
[0007] The lateral movement mechanism includes a turntable, a lateral sliding mechanism, a lateral frame, and a fixed plate. The turntable is connected to the output end of the lateral drive mechanism. The fixed plate is located at the edge of the turntable. The fixed plate is connected to the lateral frame through the lateral sliding mechanism. The lateral frame is connected to the end of the lateral rod.
[0008] The output end of the material roll drive mechanism is connected to the material roll mechanism through a transmission mechanism, and the guide wheel is directly opposite the material roll mechanism.
[0009] Furthermore, the outer wall of the guide wire wheel is provided with a guide wire groove, and the cross-section of the guide wire groove is V-shaped.
[0010] Furthermore, the guide wire groove is provided with multiple oil discharge holes in the middle, and each oil discharge hole is connected to the outside through an oil guide hole.
[0011] Furthermore, the inner wall of the guide wire groove is provided with an anti-slip structure, which is a spiral groove, a cross mesh pattern, or a transverse stripe.
[0012] Furthermore, the transverse sliding mechanism includes a linear guide rail and a movable slider. The fixed plate is connected to the movable slider, the movable slider is connected to the transverse frame, and the movable slider slides in cooperation with the linear guide rail.
[0013] Furthermore, the guiding structure is a linear bearing.
[0014] Furthermore, the lateral drive mechanism is a first geared motor, and the material roll drive mechanism is a second geared motor.
[0015] Furthermore, the transmission mechanism includes a timing belt and a rotating shaft. The output end of the second geared motor is connected to the rotating shaft via the timing belt, and the end of the rotating shaft is connected to the material roll mechanism.
[0016] Compared with the prior art, the winding device for a wet spinning machine described in this utility model has the following advantages:
[0017] 1. The lateral movement mechanism drives the guide rollers and fibers to move laterally during the winding process, preventing fibers from accumulating in a fixed position and ensuring even distribution. This avoids the accumulation and adhesion problems caused by winding fibers in a fixed position, making it particularly suitable for winding wet fibers and improving the overall winding quality. Through the lateral movement of the lateral movement mechanism, the fibers can form neat and uniform rolls during winding. Uniform distribution makes subsequent unwinding and use easier, reducing processing difficulties caused by uneven rolls and improving production efficiency. The uniform winding method reduces excessive compression between fibers, lowering friction and tensile stress during winding and preventing fiber breakage or damage due to uneven tension. This has a significant effect on improving fiber quality and ensuring product consistency.
[0018] 2. The guide roller, with its guide grooves and anti-slip texture, effectively guides the fiber along a fixed path, preventing it from deviating or tangling. This path stability contributes to the smooth operation of the fiber during high-speed winding, avoiding unnecessary bending or twisting. The anti-slip textures on the guide roller surface (such as spiral grooves, cross-grid patterns, or transverse stripes) and the V-shaped cross-section design of the guide grooves increase the friction between the fiber and the guide roller, preventing the fiber from slipping during high-speed operation. Simultaneously, the anti-slip structure reduces the adhesion of wet fibers, improving fiber winding quality. Multiple oil drain holes in the center of the guide grooves drain residual oil from lubrication or processing liquids generated during the spinning process, preventing oil buildup on the guide roller. This ensures the fiber is less contaminated as it passes through the guide roller, maintaining fiber cleanliness and contributing to improved product quality. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0030] A winding device for a wet spinning machine, such as Figure 1 As shown, it includes a transverse drive mechanism 401, a roll drive mechanism 501, a transverse movement mechanism, a roll mechanism 101, a guide structure 301, a transverse movement rod 201, and a guide wheel 202; one end of the transverse movement rod 201 is connected to the guide wheel 202 through a bearing 203, and the other end of the transverse movement rod 201 is connected to the transverse movement mechanism; the output end of the transverse drive mechanism 401 is connected to the transverse movement mechanism; and the transverse movement rod 201 is slidably engaged with the housing of the wet spinning machine through the guide structure 301.
[0031] like Figure 2 and 4As shown, the transverse movement mechanism includes a turntable 304, a transverse sliding mechanism, a transverse frame 302, and a fixed plate. The turntable 304 is connected to the output end of the transverse drive mechanism 401. The fixed plate is located at the edge of the turntable 304 and is connected to the transverse frame 302 via the transverse sliding mechanism. The transverse frame 302 is connected to the end of the transverse rod 201. The transverse sliding mechanism includes a linear guide rail 303 and a movable slider. The fixed plate is connected to the movable slider, and the movable slider is connected to the transverse frame 302. The movable slider and the linear guide rail 303 are in sliding engagement. The guide structure 301 is a linear bearing 203. The transverse drive mechanism 401 is a first geared motor, and the material roll drive mechanism 501 is a second geared motor.
[0032] The lateral movement mechanism drives the guide roller 202 and the fiber to move laterally during the winding process, preventing the fiber from accumulating in a fixed position and ensuring its even distribution. This avoids the accumulation and adhesion problems caused by winding fibers in a fixed position, making it particularly suitable for winding wet fibers and improving the overall winding quality. Through the lateral movement of the lateral movement mechanism, the fiber can form a neat and uniform roll during winding. This uniform distribution makes subsequent unwinding and use easier, reducing processing difficulties caused by uneven rolls and improving production efficiency. The uniform winding method reduces excessive compression between fibers, lowers friction and tensile stress during winding, and prevents fiber breakage or damage due to uneven tension. This has a significant effect on improving fiber quality and ensuring product consistency.
[0033] The guide roller 202 has a guide groove on its outer wall, with a V-shaped cross-section. Multiple oil drain holes 2021 are located in the center of the guide groove, each connected to the outside via an oil drain hole. The inner wall of the guide groove has an anti-slip structure, which can be a spiral groove, a cross-grid pattern, or transverse stripes. Through the guide groove and anti-slip texture, the guide roller 202 effectively guides the fiber along a fixed path, preventing fiber deviation or entanglement. Path stability contributes to the smooth operation of the fiber during high-speed winding, avoiding unnecessary bending or twisting. The anti-slip texture (such as spiral grooves, cross-grid patterns, or transverse stripes) on the surface of the guide roller 202 and the V-shaped cross-section design of the guide groove increase the friction between the fiber and the guide roller 202, preventing the fiber from slipping during high-speed operation. Simultaneously, the anti-slip structure also reduces the adhesion of wet fibers, improving fiber winding quality. Multiple oil drain holes 2021 are provided in the center of the guide groove to drain residual oil generated by lubrication or treatment liquids during the spinning process, preventing oil from accumulating on the guide roller 202. This ensures that the fibers are not easily contaminated as they pass through the guide roller 202, keeping them clean and improving product quality.
[0034] The output end of the material roll drive mechanism 501 is connected to the material roll mechanism 101 through a transmission mechanism, and the guide wheel 202 is directly opposite the material roll mechanism 101. The transmission mechanism includes a synchronous belt 502 and a rotating shaft. The output end of the second reduction motor is connected to the rotating shaft through the synchronous belt 502, and the end of the rotating shaft is connected to the material roll mechanism 101.
[0035] The working method of this embodiment
[0036] After the first geared motor of the transverse drive mechanism 401 starts, it drives the turntable 304 to rotate, driving the moving slider to perform circular motion and linear reciprocating motion in the horizontal direction. Since the geared motor can adjust the rotation speed, the rotation rate of the turntable 304 can be precisely controlled, ensuring the smoothness and control accuracy of the transverse movement. The rotation of the turntable 304 generates a mechanical thrust between the linear guide rail 303 and the slider. As the cam rotates to different positions, this thrust is transmitted along the linear guide rail 303, pushing the fixed plate to move along the guide rail via the moving slider. The bottom of the fixed plate rotates in conjunction with the turntable via a shaft and bearings. The fixed plate is connected to the transverse frame 302, causing the transverse frame 302 to also perform horizontal reciprocating motion. The movement of the transverse frame 302 drives the transverse rod 201 to slide laterally. One end of the transverse rod 201 is connected to the guide wheel 202 via a bearing 203, so the guide wheel 202 also moves along with the transverse rod 201. Lateral movement enables the reciprocating motion of the guide wheel 202, ensuring that the fibers are not concentrated in one position during winding, but are evenly distributed on the winding surface.
[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
