Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to an automatic twisting device for cable copper cores. Background Art

[0002] Conductor twisting technology plays a key role in the manufacture of cable cores. The principle is to rotate multiple strands of conductors along a spiral line to form strands, which are then grouped in a forward direction through mechanical equipment and twisted into a single conductor.

[0003] When optimizing, existing automatic twisting devices for copper core cables mostly feature rapid and precise adjustment of conductor tension and high-quality twisted wire. For example, Chinese utility model patent application number CN202223273322.2 discloses a twisting device for wire and cable processing. The device comprises a connecting shaft, a winding roller, a twisting drum and a tension adjustment mechanism. The hollow connecting shaft is arranged on a frame, and a turntable and a distribution disk are respectively provided at the front and rear ends of the connecting shaft. The two devices rotate synchronously under the action of a first driving mechanism. A plurality of pay-off rollers are evenly distributed on the circumference of the first side surface of the turntable facing the distribution disk, and the plurality of first through holes on the distribution disk correspond one to one with the plurality of pay-off rollers. The winding roller is arranged on the frame behind the distribution disk and rotates under the drive of the first motor. The twisting drum is arranged coaxially with the connecting shaft and is located between the distribution disk and the winding roller and rotates under the action of the second driving mechanism. A tension adjustment mechanism is provided on the turntable on one side of each pay-off roller. The utility model has the advantages of rapid and precise adjustment of conductor tension and high-quality twisted wire.

[0004] Although the above-mentioned automatic twisting device for copper core cables has certain advantages in terms of rapid and accurate adjustment of conductor tension and good twisted wire quality, it still has certain disadvantages: usually, the specifications of the twisted wires of multiple cables are different, and the cables need to be passed through wire barrels of different diameters. Therefore, the wire barrels need to be replaced frequently. Without external force to fix the wire barrels, the wire barrels will swing back and forth during the twisting process.
