[0021] This utility model provides an improved synthetic fiber yarn winding device, such as... Figures 1-4 As shown, the device includes a frame 1, comprising a fixed clamping frame 105 and a movable clamping frame 106 arranged opposite to each other, the movable clamping frame 106 being movably mounted on the frame 1; a take-up shaft 3, rotatably mounted between the fixed clamping frame 105 and the movable clamping frame 106, for taking up chemical fiber yarn; and a guide mechanism 2, slidably mounted on the frame 1 along the axial direction of the take-up shaft 3, for guiding the chemical fiber yarn. The guiding mechanism 2 includes a guide frame 201. The guide frame 201 has a through limiting hole 205 on the side away from the equipment frame 1. A blocking arm 209 is also movably installed on the guide frame 201. The blocking arm 209 has a notch 210 on the side facing the limiting hole 205. When the chemical fiber yarn is located in the limiting hole 205, the notch 210 is used to block the limiting hole 205.

[0022] In this invention, the equipment frame 1 serves as the basic support frame for the entire device, supporting all functional components such as the clamping frame, the take-up shaft 3, and the guide mechanism 2, ensuring the overall structural stability. The fixed clamping frame 105 and the movable clamping frame 106 are arranged opposite each other, forming two-point support for the take-up shaft 3. Their function is to facilitate the installation and disassembly of the take-up shaft 3, while also jointly clamping the take-up shaft 3 to ensure that it does not loosen or shift during winding.

[0023] The guiding mechanism 2 is crucial for ensuring that the yarn is evenly wound and does not derail. The guide frame 201 is the main frame of the guiding mechanism 2 and can slide along the axial direction of the take-up shaft 3. By sliding, the yarn is driven to move back and forth along the length of the take-up shaft 3, preventing the yarn from piling up in one place.

[0024] The blocking arm 209 is movably mounted on the guide frame 201. A notch 210 is provided on the side facing the limiting hole 205, forming an openable anti-detachment structure. When the yarn passes through the limiting hole 205, the position of the blocking arm 209 is adjusted so that the notch 210 aligns with and blocks the opening of the limiting hole 205. This prevents the yarn from being squeezed, ensures the notch 210 fits the yarn, and prevents the yarn from coming out of the limiting hole 205 due to winding tension fluctuations or equipment vibration, further improving guiding reliability.

[0025] See appendix Figure 2 -Appendix Figure 3 The guide frame 201 includes a telescopic frame 206, a telescopic cavity 207 is provided in the telescopic frame 206, and a blocking arm 209 is movably disposed in the telescopic cavity 207; a slot 208 communicating with the telescopic cavity 207 is provided on the telescopic frame 206; and a lever 212 located in the slot 208 is provided on the blocking arm 209.

[0026] In this embodiment, the controllable movement of the blocking arm 209 is achieved through the design of the telescopic cavity 207 and the lever 212, which facilitates yarn insertion and ensures stable anti-loosening function. The telescopic frame 206 is a protrusion or frame structure on the guide frame 201, which is equivalent to the slide rail base of the blocking arm 209. The telescopic cavity 207 inside is a hollow cavity, which provides space and track for the blocking arm 209 to slide, restricting the blocking arm 209 to move only along the axial direction of the telescopic cavity 207 and preventing deviation.

[0027] The slot 208 is formed on the side of the telescopic frame 206 and communicates with the telescopic cavity 207. Its length is usually matched to the required stroke of the blocking arm 209, making the internal structure visible while providing a moving channel for the lever 212. During the yarn threading stage, the operator moves the lever 212 away from the limiting hole 205. The lever 212 slides along the slot 208, causing the blocking arm 209 to retract into the telescopic cavity 207. At this time, the opening of the limiting hole 205 is fully exposed, facilitating the passage of the chemical fiber yarn through the limiting hole (preventing the blocking arm from obstructing the yarn threading operation).

[0028] During the working phase, after the yarn is threaded, the operator moves the lever 212 towards the limiting hole 205, and the blocking arm 209 extends from the telescopic cavity 207 until its notch 210 is accurately aligned with the limiting hole 205. At this time, the notch 210 closes the opening of the limiting hole 205, which neither squeezes the yarn nor prevents the yarn from coming out of the limiting hole 205 due to vibration or tension fluctuations.

[0029] See appendix Figure 3 The shielding arm 209 is connected to a first reset member 211, and the shielding arm 209 is connected to the inner wall of the telescopic cavity 207 through the first reset member 211.

[0030] In this embodiment, the first reset member 211, through its elastic force, enables the blocking arm 209 to automatically return to its working state after operation. The first reset member 211 is typically an elastic element, such as a compression spring, with its two ends connected to the inner walls of the blocking arm 209 and the telescopic cavity 207, respectively.

[0031] When the operator moves lever 212, causing the blocking arm 209 to retract into the telescopic cavity 207, i.e., away from the limiting hole 205, to make room for yarn threading, the first reset member 211 is compressed, storing elastic potential energy. When the operator releases lever 212, the reset member releases its elastic potential energy, generating a thrust that drives the blocking arm 209 to automatically extend from the telescopic cavity 207 and return to its initial working position. At this time, the notch 210 is precisely aligned with the limiting hole 205, thus restoring the anti-loosening blocking of the yarn.

[0032] See appendix Figure 1 -Appendix Figure 2 A threaded cylinder 202 is provided on the guide frame 201; a mounting frame 102 is provided on the equipment frame 1, and a motor 103 is mounted on the mounting frame 102. A threaded rod 104 is provided at the output end of the motor 103; the threaded rod 104 is threadedly connected to the inner wall of the threaded cylinder 202.

[0033] In this embodiment: the precise and controllable movement of the guide frame 201 is achieved through the lead screw transmission structure of the motor 103 and the threaded rod 104, providing power for the uniform winding of the chemical fiber yarn. The rotational motion of the motor 103 is converted into the linear reciprocating motion of the guide frame 201 through threaded engagement. The threaded rod 104 is driven to rotate by the motor 103 and has continuous threads machined on its surface. The thread 202 is fixed to the guide frame 201, and its inner wall is machined with internal threads that match the threaded rod.

[0034] When the motor 103 drives the threaded rod 104 to rotate forward or in reverse, the rotational force of the threaded rod 104 is transmitted to the threaded cylinder 202 through the thread engagement. Since the guide frame 201 is restricted to sliding along the winding shaft 3 and cannot rotate with the threaded rod, the threaded cylinder 202 will carry the guide frame 201 to make reciprocating linear motion along the axial direction of the threaded rod 104.

[0035] When the take-up shaft 3 rotates to take up the yarn, the motor 103 drives the guide frame 201 to move slowly back and forth along the axial direction. The speed matches the rotation speed of the take-up shaft 3. The yarn passing through the limiting hole 205 of the guide frame 201 will be distributed left and right as the guide frame 201 moves, and finally evenly wound on the take-up shaft 3 to form a flat and tight roll.

[0036] See appendix Figure 1 -Appendix Figure 2 The guide frame 201 has multiple supports 203 on one side facing the equipment frame 201. The bottom of the multiple supports 203 is provided with a first T-shaped seat 204. The guide frame 201 has multiple first T-shaped grooves 101 corresponding to the multiple supports 203. In the corresponding supports 203 and first T-shaped grooves 101, the first T-shaped seat 204 is slidably disposed in the first T-shaped groove 101.

[0037] In this embodiment: the bracket 203 is a support member connecting the guide frame 201 and the first T-shaped seat 204. The function of multiple brackets 203 is to distribute the weight and force of the guide frame 201 to the T-shaped seat, avoiding excessive force at a single point that could lead to deformation. The bottom of the first T-shaped seat 204 is T-shaped and fixed to the bottom of the bracket 203, serving as a sliding member that contacts the equipment frame 1. The first T-shaped groove 101 is formed on the equipment frame 1, and its shape matches the T-shaped seat, serving as the slide rail for the T-shaped seat.

[0038] The extension direction of the T-slot is consistent with the axial direction of the take-up shaft 3. The T-slot can only slide along the length of the slot and cannot deflect in a direction perpendicular to the axial direction, which strictly limits the motion freedom of the guide frame 201 and ensures that its sliding trajectory is completely parallel to the axial direction of the take-up shaft.

[0039] See appendix Figure 4 The movable clamping frame 106 is provided with a plurality of second T-shaped seats 109, and the equipment frame 1 is provided with a plurality of second T-shaped slots 108 corresponding to the plurality of second T-shaped seats 109; in the corresponding second T-shaped seats 109 and second T-shaped slots 108, the second T-shaped seats 109 are slidably disposed in the second T-shaped slots 108; a second reset member 110 is also provided in the second T-shaped slots 108, and the other end of the second reset member 110 is connected to the movable clamping frame 106.

[0040] In this embodiment, the mating logic between the second T-shaped seat 109 and the second T-shaped groove 108 is consistent with that of the first T-shaped structure, belonging to a T-shaped slide rail design. The second T-shaped seat 109 is fixed on the movable clamping frame 106, with a T-shaped bottom. The second T-shaped groove 108 is formed on the equipment frame 1, and its groove shape matches the T-shaped seat. The core function of this structure is to restrict the movement direction of the movable clamping frame 106 and prevent it from slipping off. The movable clamping frame 106 can only slide along the extension direction of the second T-shaped groove 108, that is, towards or away from the fixed clamping frame 105, and cannot deviate in the vertical direction.

[0041] When loading and unloading the rewinding shaft 3, it is necessary to increase the distance between the fixed clamping frame 105 and the movable clamping frame 106. At this time, the operator pulls the movable clamping frame 106 away from the fixed clamping frame 105. The second T-shaped seat 109 slides along the second T-shaped groove 108, and at the same time the second reset member 110 is compressed to store elastic potential energy.

[0042] After installation, the moving clamp 106 is released, and the second reset member 110 releases its elastic potential energy, generating a pulling and pushing force, which drives the moving clamp 106 to slide automatically toward the fixed clamp 105 until the clamps at both ends tightly clamp the take-up shaft 3. The take-up shaft 3 usually has shoulders or grooves at both ends, which cooperate with the clamps to achieve positioning.

[0043] See appendix Figure 4 The movable clamp 106 is also equipped with a handle 111.

[0044] In this embodiment: the handle 111 is an operation auxiliary structure of the movable clamp 106, which provides a clear and effortless force application point for the operator to push and pull the movable clamp, and further optimizes the loading and unloading process of the winding shaft 3.

[0045] See appendix Figure 1 and attached Figure 4 Both the fixed clamp 105 and the movable clamp 106 are equipped with corresponding bearings 107, and both ends of the winding shaft 3 are movably installed in the bearings 107.

[0046] In this embodiment, bearing 107 achieves low-friction, smooth rotation, which, in conjunction with external power equipment, provides stable rotational power for the winding of chemical fiber yarn, ensuring smooth winding operation. The core function of bearing 107 is to reduce friction and ensure rotational accuracy. Bearing 107 is typically a deep groove ball bearing, suitable for high-speed rotation scenarios, and is installed on the fixed clamping frame 105 and the moving clamping frame 106. The inner rings of the bearing are embedded at both ends of the winding shaft 3. Bearing 107 replaces sliding friction with rolling friction, significantly reducing rotational resistance, minimizing component wear, and extending the service life of the winding shaft and clamping frame.

[0047] An external power device is connected to one end of the take-up shaft 3 through a transmission structure, such as a pulley, gear, or coupling, to drive the take-up shaft 3 to rotate at high speed around the inner ring of the bearing 107.

[0048] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and inventive features disclosed herein.
