When coiling, the eleventh air cylinder 75 drives the first rotary supporting plate 74 to ascend, the winding supporting shaft 77 passes through the second rotary supporting plate 76 to form a winding limiting core disc, the claw opening mechanism 79 ascends to a set position along with the first rotary supporting plate 74, then the twelfth air cylinder 791 is started, the jacking block 792 extends upwards and drives the jacking driving rod 783 to move upwards, so that the clamping jaw 786 is opened, after the end part of the single strand of multi-strand wire wound by the adhesive tape is pulled to the position of the wire clamping jaw 78, the jacking block 792 descends, and the clamping jaw 786 clamps the end part of the wire under the action of the elastic piece 787; then ninth motor 72 starts, drive second rotation support plate 76 and winding support shaft 77 synchronous revolution, with the wire rod around establishing in winding support shaft 77 periphery, form the reel form, accomplish the lapping operation, after the lapping, jacking piece 792 rises, drive clamping jaw 786 is opened, second rotation support plate 76 continues rotatory angle of setting again for the wire rod breaks away from out clamping jaw 786, then take away the wire rod of lapping, when taking away, winding support shaft 77 can cooperate and carry out the descending movement, conveniently take out the wire rod.

The operation flow of the automatic offline stranding and coiling device 100 for the multiple strands of thin wires in the embodiment is as follows: a plurality of thin wire coils needing stranding are fixed on a pay-off support shaft 122 of the unreeling driving assembly 12 for automatic unreeling, and the wires are sequentially output to the wire feeding unit 2 through the tension control assembly 13 and the wire branching assembly 14; in the wire feeding unit 2, the wires are subjected to stress relief and shaping by the shaping assembly 22, then enter the wire feeding roller assembly 24 by the single-wire conveying assembly 23, and are conveyed forward one by the wire feeding roller assembly 24; then enters a third conduit 36 of the wire cutting unit 3, and during the process, the laser marking unit 9 performs laser marking on the surface of each wire according to the set interval length; when the wire needs to be cut off, the second air cylinder 244 drives the driven wire pressing wheel 243 to press the wire tightly, so that the wire is kept still, and then the lower cutter 32 and the upper cutter 33 are matched together to cut off the wire; if the wire does not need to be cut, the wire is output from the third wire conduit 36 and enters the fourth wire conduit 42 of the bunching die 4, is primarily bunched through the bunching enclosure cover 45, and is further bunched and extruded through the first bunching clamping jaw 51 and the second bunching clamping jaw 53 in the bunching extrusion unit 5; after the bunching is completed, the end part of the wire rod is clamped by the clamping and pulling unit 8, then the adhesive tape is wound on the outer peripheral surface of the single bunched and multi-strand wire rod after the bunching through the adhesive tape wrapping unit 6 until the end part of the wire rod can be pulled to the wire rod clamping jaw 78 of the coiling unit 7 and clamped, then the coiling unit 7 is started, and the wire rod is automatically coiled.

The automatic stranding and coiling equipment 100 that rolls off production line of this embodiment can realize the stranding and coiling operation of 30 strands of wire rods, realizes automatic production line, has improved efficiency and the degree of automation that the stranded fine rule rolled off production line greatly, and has improved the quality of the coiling of rolling off production line.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
