Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and more specifically, it is a stranding device for cable production. Background Art

[0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer, and is a wire for transmitting electricity or information from one end to the other. Cables are usually stranded together in multiple strands or multiple groups (each group having at least two strands) to support a structure similar to a rope. The conductors in each group are insulated from each other and are twisted around a central axis, and only the entire outside is wrapped with a highly insulating covering layer.

[0003] The stranding of cable conductors is generally carried out by large-scale mechanical stranding, with relatively high manufacturing costs. In some small cable processing workshops, cables are still manufactured by manual stranding. The method of manually stranding cables is to directly twist two or more conductors together by hand. Although the cost of manually stranding cable wires is low, the working efficiency is also very low. Therefore, stranding devices for cables have emerged on the market. Their principle is to pass multiple cables through a wire reel, and through the rotation of the wire reel and the cooperation of the take-up reel for taking up the wire, the cable is stranded and wound up.

[0004] However, when the current cable stranding device is in use, the operation of threading the cable into the stranding holes of the stranding reel is inconvenient. The main reason is that the stranding holes of the current stranding reel cannot be opened from the outside. When threading the cable, it is necessary to thread the cable through like threading a needle. However, since there is a copper core inside the cable, there will also be a situation of copper core bifurcation at the break, which makes the cable threading operation inconvenient and reduces the efficiency. And when the current cable stranding device winds up the cable, there is always a swinging device to assist the winding operation. The main purpose is to prevent the wound cable from winding around one place. The swinging device drives the cable to swing so that it evenly winds around the outside of the take-up reel. However, the angle of the swinging disc of the current swinging device is fixed. This causes when there is an angular deviation between the swinging disc and the cable during the swinging process, the inner ring surface of the swinging disc will scratch the outside of the cable, affecting the processing quality.

[0005] Therefore, we disclose a stranding device for cable production. Summary of the Invention

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. The present invention will be further described below with reference to the embodiments.

[0032] Please refer to Figures 1 to 6 , in an embodiment of the present application, it includes a bottom plate 1. A first support column 2, a second support column 4, a swing mechanism 8 and a take-up reel 9 are sequentially arranged on the central axis of the bottom plate 1. The top end of the first support column 2 is rotatably connected to a winch mechanism 3;

[0033] The top end of the second support column 4 is provided with a winding drum 5, and the winch mechanism 3 and the winding drum 5 are at the same height. The winding drum 5 is used to converge and wind multiple cables passing through the winch mechanism 3 into one cable;

[0034] The swing mechanism 8 is used to support the cable passing through the winding drum 5. The take-up reel 9 is used to collect and converge the wound cable. The swing mechanism 8 adjusts the winding position while supporting the cable passing through the winding drum 5;

[0035] The winch mechanism 3 specifically includes a disk body 22, a first rotating ring 28 and a second rotating ring 23 coaxially arranged on both sides of the disk body 22. A plurality of feeding ports 25 are formed on the outer ring surface of the disk body 22. One ends of a plurality of connecting plates 6 corresponding to the number of the feeding ports 25 are arranged on the outer ring surfaces of the first rotating ring 28 and the second rotating ring 23. The other end of a single connecting plate 6 is connected to an outer buckle guard plate 26. Two outer buckle guard plates 26 corresponding to the external positions of the first rotating ring 28 and the second rotating ring 23 form a set of cover plates. And a set of cover plates are externally buckled on the outside of the corresponding feeding port 25 through the rotation of the first rotating ring 28 and the second rotating ring 23. A set of cover plates and the corresponding feeding port 25 form a wire winding channel;

[0036] A fixing ring 33 is connected to the side of the disc body 22 where the second rotating ring 23 is installed. The fixing ring 33 is buckled on the outer end surface of the second rotating ring 23 at the end surface away from the outer edge of the disc body 22.

[0037] This embodiment is implemented as follows: when in use, the cables that need to be twisted are placed inside the winch mechanism 3, the winch mechanism 3 fixes one end of the multiple cables, and then the cables are passed into the drum 5. At this time, the winch mechanism 3 is rotated by an external drive device to achieve cable twisting. When loading the cable, the winch mechanism 3 eliminates the need for punching operations and can load the cable from the outside of the winch, thereby improving the loading efficiency. The swing mechanism 8 can adjust the cable crosstalk position during the winding process to prevent the cable from being entangled on one side. The position of the rotating column 18 is mainly adjusted to drive the swing disk 17 and the supporting seat 19 to move, and the cable is overlapped on the swing disk 17. During the displacement of the swing disk 17, if there is an obstruction, the rotating column 18 will rotate inside the rotating groove 20 to prevent the swing disk 17 from causing wear on the cable, thereby improving the processing quality.

[0038] See also Figures 1 to 6 As a preferred embodiment of the present application, a third motor 31 is installed on the side of the disk body 22 where the first rotating ring 28 is installed. The power output shaft of the third motor 31 is connected to a driving tooth 30. An inner rack 29 is provided on the inner ring surface of the first rotating ring 28, and the inner rack 29 is engaged with the driving tooth 30.

[0039] Furthermore, the length of the inner rack 29 corresponds to the spacing between the two feed ports 25 , and the driving gear 30 drives the inner rack 29 to rotate at an angle that can connect multiple groups of cover plates with their corresponding feed ports 25 .

[0040] Furthermore, a through slot 32 is formed through the disc body 22 , and a connecting pin 36 is provided between adjacent side surfaces of the first rotating ring 28 and the second rotating ring 23 , and the connecting pin 36 is rotatably disposed in the through slot 32 .

[0041] Furthermore, a rolling groove 34 is formed between the end surface of the second rotating ring 23 away from the disc body 22 and the inner side of the outer edge of the fixing ring 33, and a plurality of balls 35 are arranged inside the rolling groove 34.

[0042] Furthermore, the sides of the two corresponding outer buckle guard plates 26 that are close to each other are connected with extension plates 27.

[0043] Furthermore, an arc-shaped feed plate 24 is provided on the disk surface inside each feed opening 25 .

[0044] This embodiment is implemented as follows: When feeding the winch mechanism 3, the third motor 31 drives the driving gear 30 to rotate. During the rotation of the driving gear 30, the internal rack 29 will be rotated. During the rotation of the internal rack 29, the first rotating ring 28 will be rotated. When the first rotating ring 28 rotates, the connecting pin 36 will rotate inside the through groove 32, and the second rotating ring 23 will rotate simultaneously. In this way, the connecting plate 6 on the outer sides of the first rotating ring 28 and the second rotating ring 23 will be displaced. During the displacement process, the outer buckle guard plate 26 will be displaced and separated from the feed inlet 25. In this way, the outside of the feed inlet 25 is opened. After the feeding is completely completed, at this time, through the rotation of the first rotating ring 28 and the second rotating ring 23, the outer buckle guard plate 26 is reset, so as to close the outside of the feed inlet 25.

[0045] On the end face of the second rotating ring 23 far from the disk body 22 and on the inner side of the outer eaves of the fixed ring 33, a rolling groove 34 is provided, and a number of rolling balls 35 are arranged inside the rolling groove 34, which is to fix the second rotating ring 23. At the same time, the rolling balls 35 cooperate with the rolling groove 34 to rotate, which can make the rotation of the second rotating ring 23 smoother. The mutually approaching sides of the outer buckle guard plates 26 are both connected with extension plates 27, which can completely support the feed inlet 25 when the two outer buckle guard plates 26 approach each other.

[0046] Please refer to Figure 1 and Figure 2 As shown in, the swinging mechanism 8 includes a mounting seat 13 installed on the bottom plate 1, a second motor 11 arranged at one end of the mounting seat 13, and a screw rod 15 installed inside the mounting seat 13. One end of the screw rod 15 is connected to the power output shaft of the second motor 11. A screw sleeve 14 is threadedly connected to the outside of the screw rod 15. One end of a stabilizing block 21 is connected to the outside of the screw sleeve 14, and the other end of the stabilizing block 21 is connected to a slider 12. The upper end of the slider 12 is connected to a fourth support column 16. A rotating groove 20 is provided at the top of the fourth support column 16, and one end of a rotating column 18 is rotatably connected inside the rotating groove 20. The top of the rotating column 18 is connected to a bearing seat 19, and a swinging disk 17 is rotatably connected inside the bearing seat 19.

[0047] Furthermore, both sides of the slider 12 are slidably connected to both sides of the mounting seat 13.

[0048] Furthermore, on the side of the bottom plate 1 far from the first support column 2, a third support column 7 is connected. The top of the third support column 7 is provided with a first motor 10, and the material receiving disk 9 is connected to the power output end of the first motor 10.

[0049] This embodiment is implemented as follows: During the wire winding process, the second motor 11 drives the screw rod 15 to rotate. When the screw rod 15 rotates, it drives the outer nut 14 to rotate. When the nut 14 rotates, it drives the outer stabilizing block 21 to rotate. The end of the stabilizing block 21 is located below the slider 12, and the slider 12 can be displaced outside the mounting seat 13. In this way, the stabilizing block 21 does not rotate, but drives the slider 12 and the fourth support column 16 connected above to be displaced, displacing the bearing seat 19 and the swing plate 17. During the displacement of the swing plate 17, it drives the cable to be displaced and evenly winds the cable on the take-up reel 9.

[0050] When the swing plate 17 is displaced, the rotating column 18 rotates inside the rotating groove 20, thereby adjusting the angle of the swing plate 17, thus reducing the situation of cable wear.

[0051] In summary, the present invention is provided with a winch mechanism, a swing mechanism and a winding cylinder. The winch is used in cooperation with the winding cylinder. The take-up reel twists multiple cables. When the cable is loaded, the winch mechanism eliminates the operation of punching holes and can load the cable from the outside of the winch, improving the loading efficiency. The swing mechanism can adjust the crosstalk position of the cable during the winding process to prevent the cable from winding on one side. At the same time, during the swinging process of the swing mechanism, the bearing seat can rotate to prevent the swing plate from wearing the cable, improving the processing quality.

[0052] The above schematically describes the present invention and its embodiments. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design a structural manner and an embodiment similar to this technical solution without creative work without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.

[0053] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
