9. A cable-former disconnection protection device according to claim 1, wherein: the mounting seat (12) and the vertical plate (20) are integrally formed, and the first guide wheel (11) and the second guide wheel (21) are the same in type and are arranged in an I shape.
10. A method of using the cable-former disconnection protection device of claim 1, characterized in that: the method specifically comprises the following steps:
s1, the wire harness passes through the lower part of the second guide wheel (21), passes through the upper part of the first guide wheel (11), passes through the lower part of the lower tensioning roller (8), and finally passes through the upper part of the upper tensioning roller (7) and then is connected to the cabling machine;
s2, the PLC (36) controls the motor (2) to drive the driving rotating shaft (38) to rotate anticlockwise, and the motor (2) drives the upper tensioning roller (7) to rotate anticlockwise and the lower tensioning roller (8) to rotate clockwise due to the fact that the driving gear (39) on the driving rotating shaft (38) is meshed with the driven gear (40) on the driven rotating shaft (41), and the wire harness is driven by the upper tensioning roller (7) and the lower tensioning roller (8) together;
meanwhile, under the pulling of the wire harness, the first guide wheel (11) rotates anticlockwise, and the second guide wheel (21) rotates clockwise;
s3, as the piston rod of the electric telescopic rod (6) penetrates through the reinforcing plate (18) and then is connected with the lifting plate (29), the PLC (programmable logic controller) controls the piston rod of the electric telescopic rod (6) to extend and retract, the heights of the lifting seat (10) and the first guide wheel (11) can be adjusted, and thus the first guide wheel (11) tensions the wire harness;
the upper end of the guide rail (5) is connected with a moving seat (14) in a sliding mode, the middle of the moving seat (14) is connected with a horizontal screw rod (15) in a threaded mode, the front end of the horizontal screw rod (15) penetrates through a vertical plate (17) on the guide rail (5) and then is connected with a hand wheel (16), the horizontal screw rod (15) is rotated through the hand wheel (16), the moving seat (14) can be driven to move horizontally, the wire harness is wound to the upper portion of the first guide wheel (11) through the lower portion of the second guide wheel (21), and when the moving seat (14) and the second guide wheel (21) move towards the direction of the first guide wheel (11), the wire harness is further tensioned through the second guide wheel (21), so that the wire harness is pressed and tensioned to the top of the first guide wheel (11);
s4, because the lower end of the lifting seat (10) is connected to the upper end of the bottom plate (31) through the spring (25), the two sides of the lifting seat (10) are provided with the limiting bulges (26), the limiting bulges (26) are slidably connected in the vertical sliding grooves (27) on the inner side of the limiting seat (24), the spring (25) has an elastic action on the lifting seat (10) all the time, the lifting seat (10) is ensured to be kept at a certain height, and the lower end of the limiting bulges (26) is not contacted with the first switch (42) and the second switch (43);
s5, when the motor (2) drives the driving rotating shaft (38) to rotate too fast, the wire harness is tensioned too much, or the wire harness cannot be driven by the upper tensioning roller (7) and the lower tensioning roller (8), so that the wire harness is broken;
at this moment, before the pencil is not broken, the pencil has the holding down pressure to first guide pulley (11), make spring (25) compression, lift seat (10) move down, spacing arch (26) lower extreme is pressed first switch (42) and second switch (43), make first switch (42) disconnection, second switch (43) closure, motor (2) and commercial power disconnection at this moment, the drive of tensioning roller (7) and lower tensioning roller (8) to the pencil stops, and simultaneously, PLC controller (36) control electric telescopic handle (6)'s piston rod is retracted, reduce the height of lift seat (10) and first guide pulley (11), first guide pulley (11) no longer take up the pencil, can prevent that the pencil from taking place the broken string.
