10. A method of using a stranding machine for producing concentric cable conductors according to any one of claims 1-9, characterized in that, Includes the following steps: S1. Load the wire roller with branched cable onto the main body (11) of the concentric stranding machine, then pass the branched cable through the wire passing spool (28) and the wire combining bracket (12), overlap the top of the guide wheel (482), and then connect it to the outer wall of the take-up roller (33); S2. Control the main body (11) of the concentric stranding machine to rotate and twist the branch cables. At the same time, control the winding motor (35) to drive the winding roller (33) to rotate and wind the stranded cables. S3. During the winding process, the servo motor (43) is controlled to work, which drives the lead screw (45) to rotate, so that the moving seat (46) slides left and right, causing the stranded cable to be evenly wound on the winding roller (33). S4. After the winding roller (33) is fully loaded, stop the machine temporarily, then remove the pin (38), and the winding roller (33) can be removed from the stranded cable winding mechanism (3) and the stranded cable can be transferred to the subsequent equipment for processing.
