Since the rotating ring 71 drives the torque motor 74 to rotate, the blade 75 moves in a circle around the cable, realizing the cutting of the outer skin of the cable. Function, that is, the function of peeling is realized;

The shearing mechanism 6 has the same structure as the peeling mechanism 7, and the difference is that the torque motor 74 used by the peeling mechanism 7 is different from the torque motor 74 output torque of the shearing mechanism 6, and the shearing mechanism 6 is no longer described here.

In the above structure, when placing the reel, first move the mobile trolley 1 to a suitable position, then start the electric telescopic rod 33, and the electric telescopic rod 33 is extended to make the upper end of the sleeve 31 rotate, and then pull the inner rod 32, so that The supporting shaft 36 corresponds to the central hole of the reel, and then the first leading screw 35 is rotated, and the first leading screw 35 drives the supporting shaft 36 to move inwardly, so that the inner end of the supporting shaft 36 stretches into the central hole of the reel, and then again Start the electric telescopic rod 33, and the contraction of the electric telescopic rod 33 drives the sleeve pipe 31 to reset. At this time, the support shaft 36 pulls the reel to move. When the reel contacts the first supporting wheel 23, there is a Downward force, at this time the mounting seat 22 automatically rotates forward until the first supporting wheel 23 drops to the lowest position, at this time the reel can smoothly move between the first supporting wheel 23 and the second supporting wheel 24 , since the horizontal distance between the center of rotation of the first support wheel 23 and the center of rotation of the mounting base 22 is smaller than the horizontal distance between the center of rotation of the second supporting wheel 24 and the center of rotation of the mounting base 22, and the reel is placed stably Finally, the central axis of the cable reel is positioned at the rear of the center of rotation of the mounting base 22, so the cable reel automatically moves to a stable position to complete the work of placing the cable reel, and then the outer end of the cable is placed on the supporting wheel 42, and then Turn the second lead screw 44, the second lead screw 44 drives the pressure wheel 43 to descend, so that the end of the cable is squeezed between the support wheel 42 and the pressure wheel 43, and then the cable is pulled so that the cable passes through the support tube 5 ;

When in use, the mobile trolley 1 can be placed in a suitable position, and the supporting legs 14 are grounded, and the staff pulls the cable and starts the variable frequency motor 25. At this time, the cable has an active force on the reel. After the active force is decomposed It is the downward or upward force A and the force B towards the rear of the mobile trolley 1. The existence of the force B makes the reel tend to move to the rear of the mobile trolley 1, so that the mounting seat 22 presses down the second A wedge-shaped block 26 makes the supporting leg 14 have a downward tendency, which ensures the stability of the mobile cart 1 after it is placed; it is also possible to fix the outer end of the cable in one position, move the mobile cart 1, and start the variable frequency motor 25 , to realize the function of unwinding; when the unwrapping is over, start the shearing mechanism 6 and the peeling mechanism 7, and now the first motor 73 drives the gear meshed with the outer gear ring 72 to rotate, because the outer gear ring 72 is fixed on the support tube 5 On the tube body, the first motor 73 drives the rotating ring 71 to rotate, the rotating ring 71 drives the torque motor 74 to rotate, and the torque motor 74 drives the blade 75 to rotate, so that the blade 75 exerts a certain force on the outer skin of the cable, because the rotating ring 71 drives the torque The motor 74 rotates, so the blade 75 moves circularly around the cable to realize the effect of cutting the sheath of the cable, that is, the function of peeling is realized. The working principle of the shearing mechanism 6 is the same as that of the peeling mechanism 7.
