A cabling machine wire break protection device according to claim 1, characterized in that: the bottom of the bracket (13) is arranged at the upper end of the movable seat (14) through a third bolt (22), clamping grooves (23) are formed in two sides of the mounting seat (12), and the inner side of the upper end of the bracket (13) is clamped in the corresponding clamping groove (23) and is fixed through a fourth bolt (19).
9. A cabling machine wire break protection device according to claim 1, characterized in that: 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 identical in model number and are all in I-shaped arrangement.
10. A method of using the cable-breaking protection device of claim 1, wherein: the method specifically comprises the following steps:
s1, a wire harness bypasses under a second guide wheel (21), bypasses over a first guide wheel (11) to the lower part of a lower tensioning roller (8), and bypasses over an upper tensioning roller (7) and is connected to a cabling machine;
s2, a PLC (programmable logic controller) 36 controls a motor 2 to drive a driving rotating shaft 38 to rotate anticlockwise, and as a driving gear 39 on the driving rotating shaft 38 is meshed with a driven gear 40 on a driven rotating shaft 41, the motor 2 drives an upper tensioning roller 7 to rotate anticlockwise and a lower tensioning roller 8 to rotate clockwise, and the upper tensioning roller 7 and the lower tensioning roller 8 drive a wire harness together;
simultaneously, 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 lifting plate (29) is connected after the piston rod of the electric telescopic rod (6) penetrates through the reinforcing plate (18), the piston rod of the electric telescopic rod (6) is controlled to extend and retract through the PLC (36), the heights of the lifting seat (10) and the first guide wheel (11) can be adjusted, and therefore the first guide wheel (11) can tension a wire bundle;
the upper end of the guide rail (5) is slidably connected with the movable seat (14), the middle part of the movable seat (14) is in threaded connection with the horizontal screw rod (15), the front end of the horizontal screw rod (15) is connected with the hand wheel (16) after penetrating through the vertical plate (17) on the guide rail (5), the movable seat (14) can be driven to horizontally move by rotating the horizontal screw rod (15) through the hand wheel (16), and the wire harness winds above the first guide wheel (11) through the lower part of the second guide wheel (21), so that when the movable seat (14) and the second guide wheel (21) move towards the direction of the first guide wheel (11), the second guide wheel (21) further tightens the wire harness, and the wire harness is tightly pressed at the top of the first guide wheel (11);
s4, as the lower end of the lifting seat (10) is connected to the upper end of the bottom plate (31) through the spring (25), limiting protrusions (26) are arranged on two sides of the lifting seat (10), the limiting protrusions (26) are slidably connected into vertical sliding grooves (27) on the inner side of the limiting seat (24), the spring (25) has 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 ends of the limiting protrusions (26) are 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 excessively tensioned, or the wire harness cannot be driven by the upper tensioning roller (7) and the lower tensioning roller (8), so that the wire harness can be broken;
at this moment, before the pencil is broken, the pencil has the down force to first guide pulley (11), make spring (25) compress, lift seat (10) moves down, first switch (42) and second switch (43) are pressed to spacing protruding (26) lower extreme, make first switch (42) disconnection, second switch (43) are closed, motor (2) are disconnected with the commercial power this moment, stop the drive of tensioning roller (7) and lower tensioning roller (8) to the pencil, simultaneously, the piston rod of PLC controller (36) control electric telescopic handle (6) is retracted, reduce the height of lift seat (10) and first guide pulley (11), first guide pulley (11) no longer stretches up the pencil, can prevent that the pencil from taking place the broken string.
