Description

Technical Field

[0001] This utility model relates to the field of wire and cable manufacturing equipment technology, and in particular to a cable stranding machine with controllable tension to prevent wire breakage. Background Technology

[0002] In the cable manufacturing industry, stranded wire is the core structure of power cables and communication cables. Its quality directly determines the cable's conductivity, mechanical strength, and service life. As the core equipment for stranding processing, the cable stranding machine needs to strand multiple monofilaments (copper, aluminum, alloys, etc.) into one piece according to a preset pitch. "Tension controllability" is the core prerequisite for avoiding wire breakage and ensuring stranding quality.

[0003] Traditional cable stranding machines mainly consist of a pay-off frame (for holding monofilament coils), a stranding cage (including stranding molds), a traction device (for pulling the stranded wire forward), a take-up reel, and a tension adjustment mechanism (such as friction damping and spring pressure rollers). The working principle is as follows: multiple monofilaments are released by the pay-off frame and kept at a moderate tension by tension adjustment; the stranding cage rotates to twist the monofilaments around the central axis at a set pitch and shape them by the mold; the traction device pulls out the shaped stranded wire at a uniform speed and finally winds it up by the take-up reel.

[0004] However, the existing tension adjustment mechanism lacks cleaning of the adjustment roller, which leads to sudden tension changes caused by foreign objects getting stuck. At the same time, the layout of the stranding disc and wire guide hole of the traditional stranding machine is fixed. If more strands need to be processed, the original wire feeding frame needs to be disassembled and new holes need to be drilled and installed, which seriously affects the response speed of small batch and multi-specification orders.

[0005] Therefore, a cable stranding machine with controllable tension to prevent wire breakage is provided to solve the problems mentioned in the background art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a cable stranding machine with controllable tension to prevent wire breakage, aiming to improve the problems of cleaning the adjusting roller and the inability to apply to multiple strands in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cable stranding machine with controllable tension to prevent wire breakage, comprising a base, a fixed frame fixedly connected to the upper side of the base, a wire feeding reel fixedly connected to the upper side of the fixed frame, a drive assembly connected to the left side of the wire feeding reel, an installation assembly provided to the right side of the wire feeding reel, a stranding reel provided to the right side of the installation assembly, a lifting frame provided to the right side of the stranding reel, two adjusting rollers rotatably connected inside the lifting frame, connecting plates fixedly connected to the outer sides of the lifting frame, a brush installed on the inner side of the connecting plate, a collecting groove fixedly connected to the lower side of the connecting plate, two adjusting frames installed on the upper side of the base, a sliding groove opened inside the adjusting frame, a slider provided inside the adjusting frame, a rod inserted inside the slider, an insertion hole opened inside the adjusting frame, and a spring provided on the lower side of the slider.

[0009] Furthermore, the mounting assembly includes a mounting base, which is fixedly connected to the right side of the rotating shaft. A limiting groove is formed inside the mounting base, and a mounting head is provided inside the mounting base. A limiting plate is inserted into the mounting base, and a bolt is provided inside the limiting plate. A nut is threaded onto the bolt.

[0010] Furthermore, the inside of the stranded wire reel is provided with a wire inlet hole, which is distributed in a ring shape inside the stranded wire reel.

[0011] Furthermore, the upper side of the spring is fixedly connected to the lower side of the slider, and the side of the spring away from the slider is fixedly connected to the inner bottom of the adjustment frame.

[0012] Furthermore, the insertion rod is inserted into the interior of the slider through the insertion hole.

[0013] Furthermore, the right side of the brush is in contact with the surface of the adjusting roller.

[0014] Furthermore, the stranding reel is rotatably connected to the right side of the pay-off reel.

[0025] 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.

[0026] Reference Figure 1 , Figure 4 and Figure 5One embodiment of this utility model includes a base 1, a fixing frame 3 fixedly connected to the upper side of the base 1, a pay-off reel 4 fixedly connected to the upper side of the fixing frame 3, a drive assembly 2 connected to the left side of the pay-off reel 4, and a mounting assembly 5 provided on the right side of the pay-off reel 4. The drive assembly 2 includes a drive motor 21, which is mounted on the base 1. A drive wheel 23 is fixedly connected to the output end of the drive motor 21. A rotating shaft 25 passes through the inside of the pay-off reel 4. A driven wheel 24 is fixedly connected to the left side of the rotating shaft 25. The driven wheel 24 and the outer side of the drive wheel 23 are connected by a transmission link. The mounting assembly 5 includes a mounting base 51, which is fixedly connected to the right side of the rotating shaft 25. The mounting base 51 has a limit groove 56 inside and a mounting head 52 inside. A limit plate 53 is inserted into the mounting base 51. A bolt 54 is installed inside the limit plate 53. A nut 55 is threaded onto the bolt 54. A stranded wire reel 6 is provided on the right side of the mounting assembly 5. The stranded wire reel 6 is rotatably connected to the right side of the wire feeding reel 4. The stranded wire reel 6 has a wire inlet hole 7 inside, which is distributed in a ring inside the stranded wire reel 6.

[0027] Specifically, the monofilament is placed on the pay-off reel 4. The number of wire inlets 7 to be used is determined according to the number of monofilament strands to be twisted, thereby determining whether a suitable twisted reel 6 needs to be replaced. When the twisted reel 6 needs to be replaced, the bolts 54 and nuts 55 in the mounting assembly 5 are unscrewed, and the limiting plate 53 is removed to complete the replacement and installation of the twisted reel 6. Then, the limiting plate 53 is closed and the bolts 54 and nuts 55 are tightened to fix it. The drive motor 21 is started, and the output end of the drive motor 21 drives the drive wheel 23 to rotate. The drive wheel 23 transmits to the driven wheel 24 through the synchronous belt 22. The driven wheel 24 drives the rotating shaft 25 to rotate. The rotating shaft 25 passes through the inside of the pay-off reel 4 and drives the mounting assembly 5 to rotate. The twisted reel 6 rotates synchronously with the rotating shaft 25 to realize the twisting operation of the monofilament. This enables flexible twisting of monofilaments with different numbers of strands and improves the adaptability of the equipment to multi-specification cable strands.

[0028] Reference Figures 1-3 A lifting frame 9 is provided on the right side of the strand reel 6. Two adjusting rollers 8 are rotatably connected inside the lifting frame 9. Connecting plates 10 are fixedly connected to the outer sides of the lifting frame 9. A brush 11 is installed on the inner side of the connecting plate 10. The right side of the brush 11 is in contact with the surface of the adjusting roller 8. A collection groove 12 is fixedly connected to the lower side of the connecting plate 10. Two adjusting frames 13 are installed on the upper side of the base 1. A sliding groove 14 is opened inside the adjusting frame 13. A slider 18 is provided inside the adjusting frame 13. A rod 16 is inserted inside the slider 18. An insertion hole 15 is opened inside the adjusting frame 13. The rod 16 passes through the insertion hole 15 and is inserted into the inside of the slider 18. A spring 17 is provided on the lower side of the slider 18. The upper side of the spring 17 is fixedly connected to the lower side of the slider 18. The side of the spring 17 away from the slider 18 is fixedly connected to the inner bottom of the adjusting frame 13.

[0029] Specifically, the stranded cable enters the lifting frame 9 through the guide cylinder, and after being guided by the upper side of the two rotating adjusting rollers 8 inside, it is wound onto the take-up drum. At the same time, the brushes 11 installed on the inner side of the connecting plates 10 on both sides of the lifting frame 9 rotate with the adjusting rollers 8 to clean the impurities attached to their surface. The impurities fall into the collection groove 12 below. When the amount of cable wound on the take-up drum changes, causing a change in tension, and when it is necessary to adjust the height of the adjusting roller 8, the plug rod 16 is pulled out to disengage it from the plug hole 15. The slider 18 slides along the slide groove 14 to the corresponding height. The spring 17 on the lower side of the slider 18 presses the slider 18 upward through its own elasticity. After maintaining a stable position, the plug rod 16 is inserted to fix the slider 18. Thus, the height of the adjusting roller 8 can be precisely adjusted by adjusting the height of the lifting frame 9. This achieves automatic cleaning of impurities and flexible adaptation of cable tension during the stranding process, ensuring the quality of cable stranding.

[0030] Working principle: When using this device, first place the monofilament on the pay-off reel 4. Determine the number of wire inlets 7 needed based on the number of strands of monofilament, and thus determine whether the stranding reel 6 needs to be replaced. When the stranding reel 6 needs to be replaced, loosen the bolts 54, nuts 55, and limit plates 53 to replace the stranding reel 6. Then turn on the drive motor 21. The drive motor 21 drives the drive wheel 23 to rotate. The drive wheel 23 drives the driven wheel 24 to rotate through the synchronous belt 22. The driven wheel 24 further drives the rotating shaft 25 to rotate. The rotating shaft 25 passes through the inside of the pay-off reel 4 and drives the mounting assembly 5 to rotate. The stranding reel 6 rotates with the rotating shaft 25 and then rotates to strand the wire.

[0031] When the twisted cable enters the lifting frame 9 through the guide tube and is then wound onto the two rotating adjusting rollers 8 inside the lifting frame 9 and onto the take-up drum, the brushes 11 installed on the inner side of the connecting plates 10 on both sides of the lifting frame 9 begin to clean the impurities on the surface of the adjusting rollers 8, which fall into the collection trough 12. When the take-up drum changes, the cable tension also changes. When it is necessary to adjust the height of the adjusting roller 8, first pull the plug rod 16 out of the plug hole 15, and slide the slider 18 in the slide groove 14 to the appropriate height. The spring 17 exerts an upward squeezing force on the slider 18 through its own elasticity. Then, insert the plug rod 16 to fix the slider 18, thereby adjusting the height of the lifting frame 9 and thus the height of the adjusting roller 8 according to the different tensions.

[0032] 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.
