[0026] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 , the warning mechanism 6 is connected to a sleeve frame 7 above, and a knob 11 is connected to one side of the warning mechanism 6. The warning mechanism 6 includes a telescopic slot 601, a slider 602, a plug rod 603, a gear 604, a slot 605 and a button alarm 606. A plug rod 603 is slidably penetrated on one side of the second support frame 8, and a telescopic slot 601 is provided on the inner side of the second support frame 8. The top of the telescopic slot 601 is slidably connected to the sleeve frame 7, and a button alarm 606 is installed at the bottom of the telescopic slot 601. The sleeve frame 7 is opened on one side close to the plug rod 603. A slot 605 is provided, and a slider 602 is connected above the insertion rod 603. The slider 602 is slidably connected to the inner wall groove of the second support frame 8. A gear 604 is installed in the built-in groove of the second support frame 8 close to the insertion rod 603 through a bearing. One side of the gear 604 is connected to the knob 11 through a transmission shaft. An opening is provided on the inner side of the sleeve 7. The cross-sectional shape of the slider 602 is "L"-shaped. The gear 604 and the insertion rod 603 are meshingly connected, and the side of the insertion rod 603 close to the gear 604 is provided with equally spaced tooth blocks.

[0027] In specific implementation, the twisting machine twists multiple cables into one cable. During the transmission of multiple cables, the cables may break due to tension, and it is not convenient for workers to find the breakage in the first time, resulting in reduced work efficiency. When the cables are twisted, the knob 11 can be rotated first to make the knob 11 drive the gear 604 to rotate, and the gear 604 is meshed with the plug rod 603 to drive the plug rod 603 to move to one side. At the same time, the plug rod 603 drives the slider 602 to slide to one side in the reserved groove of the second support frame 8. So that one end of the insertion rod 603 is disengaged from the slot 605, and then the sleeve 7 is pulled upward to slide the sleeve 7 upward in the telescopic slot 601, and then the cable is inserted from the opening of the sleeve 7. The cable pulls the sleeve 7 to limit the position of the sleeve 7. When the cable breaks, the sleeve 7 loses the traction of the cable, and the sleeve 7 will slide downward in the telescopic slot 601. The bottom end of the sleeve 7 contacts the button alarm 606, which can sound an alarm in the first time when the cable breaks, making it convenient for the staff to quickly discover the breakage and improve the working efficiency of the stranding detwist machine.

[0029] In specific implementation, the pay-off reel 3 of the wire detwisting machine is usually connected to the rotating shaft 10 of the wire detwisting machine by multiple bolts, which is not convenient to disassemble. When the pay-off reel 3 needs to be replaced, the fastening ring 906 can be rotated first to remove the fastening ring 906 from the limit block 901, and then the limit block 901 can be pressed to one side to make the limit block 901 disengage from the through hole 905 and squeeze the support spring 904 to contract, and then the pay-off reel 3 is lifted upward to make the pay-off reel 3 drive the docking block 903 to disengage from the docking groove 902. The pay-off reel 3 can be quickly removed from the wire detwisting machine, which is convenient for replacement, thereby improving the convenience of the wire detwisting machine.

[0030] Working principle: When using the wire detwisting machine, first, pull the cable out from the limit assembly 4, then pull it out from the sleeve 7, then pass through the wire assembly 5, then pass through the limit wheel 12 in an "S" shape, and finally pull it to the winding assembly 14, and reel it through the winding assembly 14. During the reeling process, the warning mechanism 6 will alarm in case of cable breakage.
