Description
Technical Field
[0001] This utility model relates to the field of wire and cable manufacturing equipment technology, and in particular to a passive winding machine. Background Technology
[0002] With the development and progress of the wire and cable industry, the requirements for the quality and performance of cable auxiliary materials have further increased. Functionalization, environmental friendliness, and low cost of auxiliary materials have become a consensus within the wire and cable industry. Against this backdrop, auxiliary material manufacturers are increasingly developing products that are functional, environmentally friendly, safe, efficient, cost-effective, and improve product quality and stability.
[0003] In the manufacturing process of wires and cables, the winding process is a crucial step in ensuring product quality. Traditional winding machines are generally driven by motors and controlled by frequency converters to complete the production process of unwinding and bundling multiple strands with wire. This traditional winding equipment is based on an independent motor drive and frequency converter speed regulation, and the rotation speed of the winding machine is adjusted manually.
[0004] However, existing traditional winding machine technologies have significant drawbacks:
[0005] 1. Traditional winding machines rely on manual adjustment of the rotation speed. In actual operation, it is difficult to accurately control the stability of the speed, which leads to changes in the winding pitch and affects the winding quality. This results in defects such as uneven winding and inconsistent tension, which not only affects product quality and production efficiency but also increases production costs and resource consumption.
[0006] 2. Limited production efficiency: Manual debugging not only increases the difficulty and labor intensity of operation, but also reduces production efficiency, especially in production scenarios where winding parameters need to be frequently adjusted.
[0007] 3. High energy consumption: Traditional winding machines consume relatively high energy during operation due to independent motor drive and frequency converter speed regulation, which is not conducive to achieving energy conservation and consumption reduction goals.
[0008] Therefore, there is an urgent need for a new type of winding machine to address the shortcomings of existing technologies, improve winding quality and production efficiency, reduce energy consumption and maintenance costs, and contribute to the sustainable development of the wire and cable industry.

[0009] This invention provides a passive winding machine that can solve the problems of winding quality and winding efficiency in the prior art, achieving high efficiency and energy saving, and reducing operating costs.
[0010] A passive winding machine includes a frame and a winding mechanism, a transmission mechanism, and a transmission mechanism disposed on the frame. The transmission mechanism is connected to the transmission mechanism, and the transmission mechanism is connected to the winding mechanism.
[0011] The transmission mechanism consists of a small pulley, a large pulley, a transmission shaft, a first bevel gear, and a second bevel gear. The small pulley is fixedly connected to the winding mechanism and is driven by the large pulley. The large pulley is fixedly connected to one end of the transmission shaft, and the other end of the transmission shaft is fixedly connected to the first bevel gear. The first bevel gear and the second bevel gear form a meshing transmission. The output end of the second bevel gear is fixedly connected to the transmission mechanism.
[0012] Furthermore, it also includes an inlet ring that is fixedly installed at the inlet end of the rack.
[0013] Furthermore, the winding mechanism includes a winding disc, a winding bracket, and a hollow winding shaft. The winding bracket is fixedly installed at the wire outlet end of the frame, and the hollow winding shaft is rotatably disposed inside the winding bracket. The winding disc is fixedly connected to the end of the hollow winding shaft away from the guide ring, and the other end of the hollow winding shaft is connected to a small pulley.
[0014] Furthermore, the transmission mechanism is located between the guide ring and the winding mechanism, and the transmission mechanism includes a single-groove guide wheel assembly, a flat guide wheel assembly, and a multi-groove guide wheel assembly, the multi-groove guide wheel assembly being connected to the transmission mechanism.
[0015] Furthermore, the single-groove guide wheel assembly is provided in two sets, the flat guide wheel assembly is disposed between the two sets of single-groove guide wheel assemblies, and the multi-groove guide wheel assembly is disposed below the flat guide wheel assembly.
[0016] Furthermore, the single-groove guide wheel assembly includes a first guide wheel bracket, a single-groove guide wheel, and a first guide wheel shaft.

The input end of the first guide wheel shaft is connected to a drive motor, and the output end of the first guide wheel shaft is fixedly mounted with the single-groove guide wheel.
[0017] Furthermore, the flat guide wheel assembly includes a second guide wheel bracket, a flat guide wheel, and a second guide wheel shaft. The second guide wheel bracket is fixedly mounted on the frame, and the second guide wheel shaft is rotatably disposed within the second guide wheel bracket via a bearing. The input end of the second guide wheel shaft is connected to a drive motor, and the output end of the second guide wheel shaft is fixedly mounted with the flat guide wheel.
[0018] Furthermore, the multi-groove guide wheel assembly includes a third guide wheel bracket, a multi-groove guide wheel, and a third guide wheel shaft.

One end of the third guide wheel shaft is fixedly connected to the second bevel gear, and the other end of the third guide wheel shaft is fixedly connected to the multi-groove guide wheel.
[0019] Furthermore, the drive shaft is provided with a shaft end retaining ring at one end connected to the large pulley, the output end of the first guide wheel shaft, the output end of the second guide wheel shaft, and the end of the third guide wheel shaft connected to the multi-groove guide wheel.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] like Figures 1 to 3 As shown in the figure, a passive winding machine provided by this utility model includes a frame 20 and a winding mechanism, a transmission mechanism and a transmission mechanism disposed on the frame 20. The transmission mechanism is connected to the transmission mechanism and the transmission mechanism is connected to the winding mechanism. After being transmitted through the transmission mechanism, the multi-strand single-strand belt enters the winding mechanism. At the same time, the transmission mechanism transmits power to the transmission mechanism, and the transmission mechanism drives the winding mechanism to perform stranding and winding actions on the multi-strand single-strand belt.
[0031] like Figure 1 As shown, an inlet ring 19 is fixedly installed at the wire inlet end of the frame 20. The inlet ring 19 plays a preliminary guiding role for the single strand entering the winding machine, so that the single strand can enter the subsequent transmission mechanism and winding mechanism more accurately, avoiding the single strand from deviating or tangling when entering, and ensuring the smooth delivery of the single strand.
[0032] Specifically, such as Figure 1 As shown, the winding mechanism includes a winding reel 1, a winding bracket 2, and a hollow winding shaft 3. The winding bracket 2 is fixedly installed at the wire outlet end of the frame 20. The hollow winding shaft 3 is rotatably mounted inside the winding bracket 2 via bearings. The winding reel 1 is fixedly connected to the end of the hollow winding shaft 3 away from the guide ring 19. The winding bracket 2 provides stable support and a mounting base for the hollow winding shaft 3, ensuring that the hollow winding shaft 3 can rotate stably. The hollow winding shaft 3 connects the winding reel 1 and transmits power, allowing the winding reel 1 to perform winding operations as the hollow winding shaft 3 rotates.
[0033] Specifically, such as Figure 1 and Figure 2As shown, the transmission mechanism consists of a small pulley 4, a large pulley 5, a transmission shaft 6, a first bevel gear 7, and a second bevel gear 8. The small pulley 4 is fixedly connected to the winding mechanism, specifically to the end of the hollow winding shaft 3 away from the winding disc 1. The small pulley 4 and the large pulley 5 are connected by a synchronous belt. The large pulley 5 is fixedly connected to one end of the transmission shaft 6, and the other end of the transmission shaft 6 is fixedly connected to the first bevel gear 7. A shaft end retaining ring 9 is provided at the end of the transmission shaft 6 connected to the large pulley 5. The first bevel gear 7 and the second bevel gear 8 form a meshing transmission. The output end of the second bevel gear 8 is fixedly connected to the transmission mechanism. The meshing transmission of the first bevel gear 7 and the second bevel gear 8 changes the direction of power transmission, causing the power of the transmission mechanism to be transmitted sequentially to the first bevel gear 7 and the transmission shaft 6. The transmission shaft 6 drives the large pulley 5 to rotate, and the large pulley 5 transmits power to the small pulley 4 through the synchronous belt, and then to the hollow winding shaft 3. The function of the shaft end retaining ring 9 is to prevent the large pulley 5 from axially moving on the transmission shaft 6, ensuring the stability of the transmission.
[0034] Specifically, such as Figures 1-3 As shown, the transmission mechanism is located between the guide ring 19 and the winding mechanism. The transmission mechanism includes a single-groove guide wheel 11 assembly, a flat guide wheel 14 assembly, and a multi-groove guide wheel 17 assembly. The multi-groove guide wheel 17 assembly is connected to the transmission mechanism. There are two sets of single-groove guide wheel 11 assemblies. The flat guide wheel 14 assembly is located between the two sets of single-groove guide wheel 11 assemblies, and the multi-groove guide wheel 17 assembly is located below the flat guide wheel 14 assembly.
[0035] The single-groove guide wheel 11 assembly includes a first guide wheel bracket 10, a single-groove guide wheel 11, and a first guide wheel shaft 12. The first guide wheel bracket 10 is fixedly mounted on the frame 20. The first guide wheel shaft 12 is rotatably mounted within the first guide wheel bracket 10 via bearings. The input end of the first guide wheel shaft 12 is connected to a drive motor, and the output end of the first guide wheel shaft 12 is fixedly mounted on the single-groove guide wheel 11. The flat guide wheel 14 assembly includes a second guide wheel bracket 13, a flat guide wheel 14, and a second guide wheel shaft 15. The second guide wheel bracket 13 is fixedly mounted on the frame 20. The second guide wheel shaft 15 is rotatably mounted within the second guide wheel bracket 13 via bearings. The input end of the second guide wheel shaft 15 is connected to a drive motor. A drive motor is connected, and a flat guide wheel 14 is fixedly installed at the output end of the second guide wheel shaft 15; the multi-groove guide wheel 17 assembly includes a third guide wheel bracket 16, a multi-groove guide wheel 17, and a third guide wheel shaft 18. The third guide wheel bracket 16 is fixedly installed at the bottom of the frame 20, and is rotatably mounted inside the third guide wheel bracket 16 via bearings. One end of the third guide wheel shaft 18 is fixedly connected to the second bevel gear 8, and the other end of the third guide wheel shaft 18 is fixedly connected to the multi-groove guide wheel 17; the drive motor is not shown in the figure. Shaft end retaining rings 9 are provided at the output ends of the first guide wheel shaft 12, the output ends of the second guide wheel shaft 15, and the end of the third guide wheel shaft 18 connected to the multi-groove guide wheel 17.
[0036] The single-groove guide roller 11 in the single-groove guide roller 11 assembly near the inlet ring 19 initially guides and sorts the incoming open-web single-strand belt. This makes the multi-strand single-strand belt more orderly as it enters the multi-groove guide roller 17 assembly. The multi-strand single-strand belt is then transferred from the multi-groove guide roller 17 to the flat guide roller 14, crosses the flat guide roller 14, returns to the multi-groove guide roller 17, and finally outputs through the multi-groove guide roller 17 to the single-groove guide roller 11 near the output end of the frame 20, transferring it to the winding hollow shaft 3. The multi-groove guide roller 17 first sorts the multi-strand single-strand belt, and then flattens and guides it when it reaches the flat guide roller 14, ensuring the single-strand belt is aligned in width. The upward movement becomes more uniform, and then the multi-groove guide wheel 17 transmits the flattened and guided single-strand belt to the single-groove guide wheel 11 near the output end of the frame 20 for convergence and aggregation. Finally, the winding and stranding are completed by the rotation of the winding hollow shaft 3. The multi-groove guide wheel 17 itself does not rely on an independent motor drive, but starts to rotate under the force transmitted by the multi-strand single-strand belt. This rotational power becomes the core power source of the entire winding system. The function of the shaft end retaining ring 9 is to prevent the single-groove guide wheel 11, the flat guide wheel 14 and the multi-groove guide wheel 17 from axial movement on the first guide wheel shaft 12, the second guide wheel shaft 15 and the third guide wheel shaft 18, so as to ensure the stability of the guide wheel rotation.
[0037] The working principle of this utility model is as follows.
[0038] The passive winding machine uses the stranded rope 21 as a power source and realizes the winding operation through a mechanical transmission system.
[0039] After initial guidance by the inlet ring 19, the single-strand belt first enters the single-groove guide roller 11 assembly near the inlet ring 19. The drive motor in this assembly drives the single-groove guide roller 11 to rotate, initially combing and guiding the single-strand belt, so that it enters the multi-groove guide roller 17 assembly in a regular posture. The multi-groove guide roller 17 combs the multi-strand belt and transmits it to the flat guide roller 14. Driven by the corresponding drive motor, the flat guide roller 14 flattens the single-strand belt and optimizes its width direction, ensuring that the single-strand belt is uniform. The single-strand belt processed by the flat guide roller 14 returns to the multi-groove guide roller 17, and is then transmitted by the multi-groove guide roller 17 to the single-groove guide roller 11 near the output end of the frame 20 for convergence and aggregation. Finally, the winding hollow shaft 3 completes the stranding and winding actions.
[0040] During transmission, the multi-strand single-strand belt generates friction with the multi-groove guide wheel 17, causing the multi-groove guide wheel 17 to rotate. One end of the third guide wheel shaft 18 is connected to the multi-groove guide wheel 17, and the other end is fixedly connected to the second bevel gear 8. The rotational power of the multi-groove guide wheel 17 is transmitted to the second bevel gear 8 through the third guide wheel shaft 18. The second bevel gear 8 meshes with the first bevel gear 7, changing the direction of power transmission by 90 degrees and driving the transmission shaft 6 to rotate. The large pulley 5 on the transmission shaft 6 rotates with the shaft and transmits power to the small pulley 4 through the synchronous belt. The small pulley 4 is connected to the winding hollow shaft 3, thereby driving the winding hollow shaft 3 and the winding disc 1 to rotate, completing the stranding and winding operations.
[0041] Since the rotational power of the winding reel 1 originates from the rotation of the multi-groove guide wheel 17 during the formation of the stranded rope 21, the running speed of the stranded rope 21 and the rotational speed of the winding reel 1 are always precisely matched, thus ensuring that the winding pitch remains consistent. This effectively avoids problems such as uneven winding and inconsistent tension caused by manual speed adjustment in traditional winding machines. At the same time, this design, which uses the stranded rope 21 as the power source and eliminates the need for a separate motor drive, reduces energy consumption caused by independent motor drive and frequency converter speed regulation, lowers production costs and resource consumption, and also solves the problem of hard lumps in the stranded rope 21 caused by winding, significantly improving winding quality and production efficiency.
[0042] The embodiments of this utility model have been described in detail above, but the content is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
