[0002] In modern industrial production, cables serve as a crucial medium for power transmission and signal transmission, with enormous demand and widespread applications. With technological advancements and accelerated industrialization, the requirements for cable production efficiency and quality are becoming increasingly stringent. In the cable manufacturing process, stranding is a key step in producing multi-core cables, directly impacting their performance and lifespan.

[0003] In existing technologies, the stranding mechanisms of stranding machines used in cable production generally suffer from low efficiency and complex operation. Traditional stranding mechanisms typically require manual operation to complete the cable winding and pulling process, which is not only time-consuming and labor-intensive, but also makes it difficult to ensure the uniformity and consistency of cable winding. Furthermore, when the raw material wire needs to be replaced or maintained, existing stranding mechanisms often lack the ability to quickly change and adjust, leading to production interruptions and reduced efficiency. Therefore, to address these technical problems, this application proposes a stranding mechanism for a stranding machine used in cable production. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Reference Figures 2-4 One embodiment of this utility model provides a stranding mechanism for a stranding machine used in cable production, comprising:

[0029] The support frame 1 has an electric slide rail 2 fixedly connected to its inner top wall. An L-shaped frame 3 is installed inside the electric slide rail 2. A drive gear 14 is located behind the L-shaped frame 3. A gear ring 11 is fixedly connected to the outer rear wall of the sleeve 4. The gear ring 11 and the drive gear 14 are meshed. A second motor 13 is mounted on the rear side of the L-shaped frame 3 via a fixed bracket. The drive end of the second motor 13 is fixedly connected to the outer wall of the drive gear 14. The bottom end of the L-shaped frame 3 is rotatably connected to the sleeve 4. A cable core 12 is installed on the inner wall of the sleeve 4. A top block 16 is slidably connected to the inner wall of the support frame 1. A reciprocating threaded rod 17 is rotatably connected to the inner wall of the support frame 1. Two feeding rollers are rotatably connected to the inner front wall of the support frame 1. 9. For feeding the cable core 12, a second pulley 18 is located on the outer wall of one of the feeding rollers 9 and a first pulley 10 is located on the outer wall of the reciprocating threaded rod 17. The outer walls of the first pulley 10 and the second pulley 18 are connected by a belt. A motor 8 is mounted on the outer wall of the front end of the support frame 1 through a fixed frame. The drive end of the motor 8 is fixedly connected to the outer wall of the second pulley 18. A top block 15 is fixedly connected to the inner wall of the support frame 1. The cable core 12 is set on the outer wall of the top block 15 for clamping and feeding the cable core 12. Two guide discs 7 are fixedly connected to the outer wall of the front end of the sleeve 4. Multiple guide wheels are rotatably connected to the outer wall of one of the guide discs 7.

[0030] Specifically, firstly, the cable core 12 is inserted into the inner wall of the sleeve 4. Then, one end of the cable core 12 is clamped by the top block 15 and the top block 2 16. Next, the starting motor 2 13 controls the meshing between the drive gear 14 and the gear ring 11. The gear ring 11 controls the rotation of the sleeve 4 on the outer wall of the L-shaped frame 3, allowing the raw material thread on the discharge roller 6 to be wound around the outer wall of the cable core 12. Simultaneously, the electric slide rail 2 drives the L-shaped frame 3 and the sleeve 4 to move, evenly winding the outer wall of the cable core 12. After part of the outer wall of the cable core 12 is wound, the starting motor 18 drives the upper feeding roller 9 to rotate, pulling the wound cable core 12 out of the inner wall of the sleeve 4. When the motor 18 starts, it drives the pulley 2 18 to rotate. The interaction between the belt and pulley 10 controls the rotation of the reciprocating threaded rod 17, which in turn controls the top block 2 16. The reciprocating threaded rod 17 reciprocates, pulling the clamped cable core 12 out of the inner wall of the sleeve 4 and winding the unwound raw material wire on the outer wall of the cable core 12. The length of each pull is the same as the distance that the reciprocating threaded rod 17 controls to reciprocate, realizing the cooperation between the top block 2 16 and the top block 15. When the cable core 12 is no longer clamped, the two feeding rollers 9 pull the cable core 12. When the cable core 12 is clamped, the length of the feeding rollers 9 pulling out the cable core 12 reaches the limit, the motor 1 8 is turned off, and the cable core 12 is wound again. By automatically pulling the cable core 12 out of the inner wall of the sleeve 4, the outer wall of the cable core 12 is wound evenly, which facilitates the improvement of the twisting efficiency of the cable core 12. At the same time, the guide plate 7 can guide the raw material wire, so that the raw material wire is evenly wound on the outer wall of the cable core 12.

[0031] Reference Figure 1 , Figure 5 and Figure 6 The material tray 5 is fixedly connected to the outer wall of the rear end of the sleeve 4. Multiple rotating rods 19 are rotatably connected to the outer wall of the material tray 5. The outer wall of the rotating rod 19 is provided with a discharge roller 6. The outer wall of the top end of the rotating rod 19 is provided with a fixing ring 20. The fixing block 21 is located in the fixing ring 20. The top end of the fixing block 21 is slidably connected with a plug shaft 22. One end of the plug shaft 22 facing the rotating rod 19 is located inside the rotating rod 19. The outer wall of the plug shaft 22 is sleeved with a spring 23 for limiting the discharge roller 6 by the fixing ring 20.

[0032] Specifically, when the raw material line on the outer wall of the discharge roller 6 is used up, the fixing ring 20 can be removed from the top of the rotating rod 19 by pulling the insert shaft 22 to compress the spring 23. After removing the empty discharge roller 6, a new discharge roller 6 can be replaced. Then, the fixing ring 20 is put on the top side of the rotating rod 19. Under the reset of the spring 23, the insert shaft 22 is controlled to insert into the top of the rotating rod 19, so that the fixing ring 20 is pressed on the top side of the discharge roller 6, thus completing the replacement of the discharge roller 6. The replacement of the discharge roller 6 can be completed through a simple structure and operation, which can improve the replacement efficiency of the discharge roller 6.

[0033] Working principle: First, the motor 13 is started to control the meshing between the drive gear 14 and the gear ring 11, driving the sleeve 4 to rotate at the bottom of the L-shaped frame 3, thereby rotating the material tray 5 and the guide plate 7. The material wire is fed out by the discharge roller 6, achieving the stranding of the outer wall of the cable core 12. At the same time, the electric slide rail 2 can control the movement of the L-shaped frame 3 and the sleeve 4 to achieve uniform winding of the outer wall of the cable core 12. Meanwhile, the top block 16 and the top block 15 can clamp and fix the cable core 12. When the cable core 12 needs to be pulled after the outer wall of the cable core 12 is stranded, the motor 1 is started. 8. The belt control pulley 18 and pulley 10 rotate to control the synchronous rotation of one of the feeding rollers 9 and the reciprocating threaded rod 17. This enables the two feeding rollers 9 to pull the cable core 12 and the top block 16 to fix the cable core 12. The cable core 12 is automatically pulled and wound on the outer wall. When the discharge roller 6 needs to be replaced, the fixing ring 20 can be removed from the top of the rotating rod 19 by pulling the insert shaft 22 to compress the spring 23. Then the discharge roller 6 can be replaced. The spring 23 is then reset to press the insert shaft 22 into the top of the rotating rod 19 to complete the replacement of the discharge roller 6.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
