The use method of the pay-off device of the portable tube strander for cable production as claimed in any one of claims 6 to 9, characterized by comprising the following steps: cup joint drawing drum (308) on installation lead screw (307), install fixed handle (309), rotatory tight with fixed handle (309), expose the end with the wire rod and pass adjusting part (4) earlier, pass tensioning part (5) again, carry to the pipe hank built-in through antifriction subassembly (6) and guide pulley (7) at last, specifically as follows:

during conveying, a driving motor (301) is turned on, the driving motor (301) drives a driving wheel (302) to rotate, the driving wheel (302) rotates, a driven wheel (306) is driven to rotate under the action of a driving belt (303), the driven wheel (306) rotates to drive a driving shaft (305) to rotate on a driving base (304), the driving shaft (305) drives an installation lead screw (307) to rotate, and the installation lead screw (307) rotates to drive a pay-off disc (308) to pay off;

when wires are paid off to two sides of a pay-off reel (308), the wires apply pressure to adjusting rollers (407), a pressure sensor is installed in a rotating base (406), when the adjusting roller (407) on one side is pressed, the pressure sensor feeds back signals to an external control system, the external control system controls a hydraulic cylinder (408) to be matched with a sliding rod (402) and a moving slider (403) to enable the adjusting rollers (407) to move towards the force-applying direction, an adjusting bolt (405) adjusts the distance between the two adjusting rollers (407) according to the thickness of the wires to enable the gap between the adjusting rollers (407) to be equal to the width of the wires, after the wires pass through the two adjusting rollers (407), the wires are lapped on the surfaces of guide rollers (411), and dust on the surfaces of the wires is wiped by wiping rollers (415);

the wire is lapped on a tension roller (505), the height of the tension roller (505) can be adjusted according to the tension degree of the wire, a servo motor (508) is controlled to rotate, the servo motor (508) controls a rotary lead screw (506) to rotate, the rotary lead screw (506) rotates to drive a lead screw seat (504) to move up and down, when the wire is too loose, the lead screw seat (504) is controlled to move up to tension the wire, and when the wire is too tight, the lead screw seat (504) is controlled to move down;

the wire rod enters the antifriction assembly (6) after passing through the tension roller (505), the wire rod passes through the roller (611) installed on the connecting rod (610) before entering the threading hole (603), the connecting rod (610) is connected with the spring hinge (609), when the wire rod enters the threading hole (603) at different angles, the roller (611) is matched with the spring hinge (609) to buffer the wire rod, the wire rod after passing through the roller (611) passes through the protective barrel (606), and finally the wire rod is conveyed into the pipe twisting machine through the guide of the guide wheel (7).
