Description

Technical Field

[0001] This utility model relates to the technical field of wire winding and unwinding equipment, and in particular to a winding shaft structure for a single twister. Background Technology

[0002] The single-strand winding spool is a key component in cable manufacturing equipment. Its core function is to evenly and neatly wind the twisted cable onto a reel or spool for subsequent processes. In existing technology, this winding spool typically consists of a shaft, a transmission mechanism (such as gears or belts), and a drive motor (such as a standard three-phase asynchronous motor or a variable frequency motor). Its operation mainly relies on the linkage of the main unit or a simple speed setting of the motor. Through a mechanical friction damping device or manual adjustment of the motor torque, a roughly constant resistance is applied to the winding process, thereby creating winding tension.

[0003] While this structure basically fulfills the winding function, its tension control operates in an open-loop mode, unable to automatically adjust according to actual working conditions. During winding, as the winding diameter continuously increases, the linear speed and winding torque requirements of the wire constantly change, inevitably causing tension fluctuations. This not only affects the tightness and uniformity of the winding but also makes it difficult to meet the process requirements of precision cables with high tension stability. The adaptability and controllability of the existing structure have become a limiting factor in improving the overall performance and product quality of single-strand twisters. Utility Model Content

[0004] In view of the fact that the existing take-up shaft cannot control the tension of the wire harness, and that the wire harness breaks open after winding, requiring the wire harness to be rewound around various devices before it can be re-wound, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a take-up shaft structure for a single twister, which aims to: adjust the winding tension of the wire harness and automatically fix the wire harness when it is disconnected.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a take-up shaft structure for a single twister, including a base, a take-up device fixedly installed on the top of the base, a reciprocating guide device provided on the top of the take-up device and away from the take-up device, and a tension adjustment mechanism provided on the top of the base and away from the reciprocating guide device. The tension adjustment mechanism includes a lifting assembly, which includes a placement frame. A drive motor is fixedly installed on the top of the placement frame. A threaded shaft is fixedly installed on the output end of the drive motor through a reducer. The bottom end of the threaded shaft passes through the placement frame and extends into the interior of the placement frame.

[0007] As a preferred embodiment of the take-up shaft structure for a single twister described in this utility model, the lifting assembly further includes a lifting plate, the outer surface of which is slidably connected to the inner surface of the placement frame, and the inner surface of which is threadedly connected to the outer surface of the threaded shaft.

[0008] As a preferred embodiment of the take-up shaft structure for a single twister described in this utility model, the tension adjustment mechanism further includes a fine-tuning component, which includes a voice coil motor. The output end of the voice coil motor is fixedly mounted with a rotating shaft via a coupling, and a connecting frame is fixedly mounted on the outer surface of the rotating shaft.

[0009] In a preferred embodiment of the take-up shaft structure for a single twister described in this utility model, the bottom of the voice coil motor is fixedly connected to the top of the lifting plate, and the outer surface of the connecting frame is slidably connected to the inner surface of the placement frame.

[0010] As a preferred embodiment of the take-up shaft structure for a single twister described in this utility model, the tension adjustment mechanism further includes a tension adjustment component, which includes a stress detector. The top of the stress detector is fixedly connected to the inner surface of the connecting frame, and a first spring is fixedly installed at the bottom of the stress detector. A first connecting block is fixedly installed at the bottom of the first spring.

[0011] As a preferred embodiment of the take-up shaft structure for a single twister described in this utility model, the tension adjustment assembly further includes a first rotating rod, the outer surface of which is rotatably connected to the inner surface of a first connecting block, a stress roller is fixedly installed on the outer surface of the first rotating rod, and a first guide groove is formed on the outer surface of the stress roller.

[0012] As a preferred embodiment of the take-up shaft structure for a single twister described in this utility model, the tension adjustment mechanism further includes a clamping assembly, which includes a second spring. One end of the second spring is fixedly connected to the inner wall of the connecting frame, and the other end of the second spring is fixedly mounted with a second connecting block. A second rotating rod is rotatably mounted on the inner surface of the second connecting block, and a clamping roller is fixedly mounted on the outer surface of the second rotating rod. A second guide groove is formed on the outer surface of the clamping roller.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model incorporates a stress adjustment design for the take-up shaft of a single twister. Through the coordinated use of the placement frame and drive motor with the threaded shaft and lifting plate, the coordinated use of the lifting plate and voice coil motor with the rotating shaft and connecting frame, the coordinated use of the connecting frame and stress detector with the first spring and the first connecting block, the coordinated use of the first connecting block and the first rotating rod, and the coordinated use of the first rotating rod and the stress roller, the stress value of the wire harness on the stress roller can be adjusted. This high-response micro-motion mechanism compensates for the slow response of traditional screw systems, making it particularly suitable for applications extremely sensitive to tension fluctuations.

[0014] 2. This utility model improves upon the design of clamping and fixing broken wire harnesses by adding a wire harness breakage clamp. Through the cooperation of the connecting frame and the second spring with the second connecting block and the second rotating rod, and the cooperation of the second rotating rod and the second guide groove, the wire harness is clamped in the first and second guide grooves during the winding process. This prevents the wire harness from being snapped back after breaking, thus avoiding the need to spend time re-winding the guide. Attached Figure Description

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0018] Reference Figures 1-3 This is the first embodiment of the present utility model, which provides a take-up shaft structure for a single twister. This take-up shaft structure for a single twister includes a base 1, a winder 2 is fixedly installed on the top of the base 1, a reciprocating guide 3 is provided on the top of the winder 2 and away from the winder 2, and a tension adjustment mechanism 4 is provided on the top of the base 1 and away from the reciprocating guide 3. The tension adjustment mechanism 4 includes a lifting assembly 41, which includes a placement frame 411. A drive motor 412 is fixedly installed on the top of the placement frame 411. A threaded shaft 413 is fixedly installed on the output end of the drive motor 412 through a reducer. The bottom end of the threaded shaft 413 passes through the placement frame 411 and extends into the interior of the placement frame 411.

[0019] The lifting assembly 41 also includes a lifting plate 414, the outer surface of which is slidably connected to the inner surface of the placement frame 411, and the inner surface of the lifting plate 414 is threadedly connected to the outer surface of the threaded shaft 413.

[0020] The tension adjustment mechanism 4 also includes a fine-tuning component 42, which includes a voice coil motor 421. The output end of the voice coil motor 421 is fixedly mounted with a rotating shaft 422 via a coupling, and a connecting bracket 423 is fixedly mounted on the outer surface of the rotating shaft 422.

[0021] The bottom of the voice coil motor 421 is fixedly connected to the top of the lifting plate 414. The outer surface of the connecting frame 423 is slidably connected to the inner surface of the placement frame 411.

[0022] The tension adjustment mechanism 4 also includes a tension adjustment component 43, which includes a stress detector 431. The top of the stress detector 431 is fixedly connected to the inner surface of the connecting frame 423, and a first spring 432 is fixedly installed at the bottom of the stress detector 431. A first connecting block 433 is fixedly installed at the bottom of the first spring 432.

[0023] The tension adjustment assembly 43 also includes a first rotating rod 434, the outer surface of the first rotating rod 434 is rotatably connected to the inner surface of the first connecting block 433, a stress roller 435 is fixedly installed on the outer surface of the first rotating rod 434, and a first guide groove 436 is formed on the outer surface of the stress roller 435.

[0024] During use, when the wire harness is being wound up, it is squeezed by the stress roller 435. The stress of the wire harness is first transmitted to the first rotating rod 434 through the stress roller 435, and then to the stress detector 431 through the first spring 432. When the stress detected by the stress detector 431 undergoes a small reciprocating change, the voice coil motor 421 drives the connecting frame 423 to move through the rotating shaft 422. The connecting frame 423 drives the stress roller 435 to quickly adjust the small stress. When the stress detector 431 detects a large stress change, the drive motor 412 drives the threaded shaft 413 to rotate. The threaded shaft 413 drives the equipment on the lifting plate 414 to move up and down. Example 2

[0025] Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the tension adjusting mechanism 4 further includes a clamping assembly 44. The clamping assembly 44 includes a second spring 441. One end of the second spring 441 is fixedly connected to the inner wall of the connecting frame 423. The other end of the second spring 441 is fixedly installed with a second connecting block 442. A second rotating rod 443 is rotatably installed on the inner surface of the second connecting block 442. A clamping roller 444 is fixedly installed on the outer surface of the second rotating rod 443. A second guide groove 445 is opened on the outer surface of the clamping roller 444.

[0026] During use, after the winding device 2 finishes winding the wire harness, it cuts the wire harness. The second spring 441 drives the second rotating rod 443 to move through the second connecting block 442. The second rotating rod 443 drives the clamping roller 444 to move, so that the clamping roller 444 and the stress roller 435 tightly clamp the wire harness without affecting the movement of the wire harness.

[0027] The remaining structure is the same as that in Example 1.

[0028] Based on embodiments 1-2, the working principle of this utility model is as follows: When the single twisted machine take-up shaft starts working, the take-up coil 2 winds up the wire harness, and the reciprocating guide 3 reciprocates and guides the wire harness. When the wire harness is being wound, it is squeezed by the stress roller 435. The stress of the wire harness is first transmitted to the first rotating rod 434 through the stress roller 435, and then transmitted to the stress detector 431 through the first spring 432. When the stress detected by the stress detector 431 undergoes a slight reciprocating change, the voice coil motor 421 drives the connecting frame 423 to move through the rotating shaft 422. 3. The stress roller 435 is driven to quickly adjust the small stress. When the stress detector 431 detects a large stress change, the drive motor 412 drives the threaded shaft 413 to rotate. The threaded shaft 413 drives the equipment on the lifting plate 414 to move up and down. After the winding device 2 finishes winding the wire harness, it cuts the wire harness. The second spring 441 drives the second rotating rod 443 to move through the second connecting block 442. The second rotating rod 443 drives the clamping roller 444 to move, so that the clamping roller 444 and the stress roller 435 tightly clamp the wire harness without affecting the movement of the wire harness.
