Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to a positioning structure for twisting multi-core cables. Background Art

[0002] Cables are cables with special purposes that can be used in specific occasions. When the current that the cable needs to carry is too large, the diameter of the cable core is relatively large. In normal production and use, the cable core of large-diameter cables is not a whole cable core with a larger diameter due to limitations in materials and processes, but is made up of multiple wires twisted together.

[0003] Prior art (publication number: CN 220020733 U) A conductor twisting structure for preparing cables, comprising: a workbench, a power device, a feeding device, a twisting device, a wire bundling device and a wire gathering device, the workbench is sequentially provided with the power device, the feeding device, the twisting device, the wire bundling device and the wire gathering device, the power device is coaxially connected to the feeding device, the power device passes through the feeding device and is coaxially connected to the twisting device, the twisting device comprises: a disc fixing seat, a disc assembly block, a disc outer ring, a threading hole and a groove, a disc fixing seat is installed on the workbench, a disc outer ring is slidably connected to the disc fixing seat, and the disc outer ring is connected to a plurality of disc assembly blocks by bolts.

[0004] Although the above patent realizes the replacement of a single wearing part without cutting the wire core, thus reducing the maintenance time, it has the following disadvantages: when in use, the wire bundling device cannot be moved, which will cause the twisted cable to be unable to be evenly wound on the wire roller. The uneven winding method will cause a waste of available space on the wire roller and reduce the efficiency of cable storage. Further improvement is needed. For this reason, we propose a positioning structure for twisting multi-core cables. Utility Model Content

[0005] The main purpose of the utility model is to provide a positioning structure for twisting multi-core cables, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A positioning structure for twisting a multi-core cable comprises a base plate, a stranding component is installed on the left upper end of the base plate, a U-shaped frame is installed on the middle right upper end of the base plate, two L-shaped plates symmetrically distributed front and back are installed on the upper right upper end of the base plate, a slide groove is opened on the upper end of the U-shaped frame, a wire rack is arranged in the slide groove and in the middle and rear upper end of the base plate, a rotatable wire-taking roller is arranged between the two L-shaped plates, a connecting component is arranged at the front end of the front L-shaped plate, and a positioning component is arranged in the U-shaped frame.

[0015] 1. By arranging the alignment component, the cable can be evenly wound on the wire take-up roller. During use, control the reciprocating lead screw to rotate. The reciprocating lead screw drives the connecting plate to move forward. When the connecting plate moves to the end, the connecting plate moves backward. Similarly, drive the connecting plate to move reciprocally, so that the connecting plate drives the wire holder to move reciprocally, making the stranded cable align with the unwound part of the wire take-up roller and evenly winding on the wire take-up roller, reducing the waste of available space on the wire roller and improving the efficiency of cable storage;

[0016] 2. By setting up the connecting component, it can drive the alignment component to rotate. When the second motor drives the wire take-up roller to rotate, the wire take-up roller drives the first gear to rotate through the connecting shaft, the first gear drives the second gear to rotate, the second gear drives the driven wheel to rotate through the driving wheel, and the driven wheel drives the reciprocating lead screw to rotate. When the wire take-up roller rotates one circle, it can drive the reciprocating lead screw to rotate one circle synchronously. The synchronous rotation can effectively avoid the cumulative error caused by asynchronous operation, ensure that each winding can be accurately in place, and improve the accuracy of wire winding.

[0026] In order to align the well-stranded cable with the non-wound part of the take-up roller 13, wind it evenly on the take-up roller 13, reduce the waste of the available space on the wire roller, and improve the efficiency of cable storage. By setting the alignment component 15, the cable can be guided to wind evenly on the take-up roller 13. The specific structure is as follows: The alignment component 15 includes a reciprocating lead screw 151. The reciprocating lead screw 151 is movably connected to the rear inner wall of the U-shaped frame 9. The reciprocating lead screw 151 is movably connected to the U-shaped frame 9 through a bearing.

The second gear 123 drives the driven wheel 125 to rotate through the driving wheel 124, and the driven wheel 125 drives the reciprocating lead screw 151 to rotate. When the take-up reel 13 rotates one circle, it can synchronously drive the reciprocating lead screw 151 to rotate one circle. The reciprocating lead screw 151 drives the connecting plate 152 to move forward. When the connecting plate 152 moves to the end, the connecting plate 152 moves backward. Similarly, it drives the connecting plate 152 to move reciprocally, so that the connecting plate 152 drives the wire guiding frame 8 to move reciprocally, making the stranded cable align with the unwound part of the take-up reel 13 and be evenly wound on the take-up reel 13.
