[0002] Optical-electric composite cable is a new type of access method that is suitable for use as a transmission line in broadband access network systems. It integrates optical fiber and power transmission copper wire, and can solve the problems of broadband access, equipment power consumption, and signal transmission. The diversity of optical-electric composite cables determines the complexity of the cable structure due to their diverse functions. The structure of the composite cable is usually composed of two parts: a cable core and a sheath of a layer-twisted structure. The sheath includes a sheath and an outer sheath. During the production process, the composite cable needs to be cut according to the actual situation.

[0003] The existing cutting equipment lacks a limit on the composite cable during its movement, causing the composite cable to be offset. When the composite cable is cut using a tool for a long time, the tool is easily damaged, and it is inconvenient to replace the tool. Therefore, the present invention proposes an optoelectronic composite cable cutting device and a cutting method thereof to solve the above problems. Summary of the invention

[0061] Working principle: When the composite cable needs to be cut, the composite cable is first placed in the middle of the four electric conveyors 3, and the control rod 14 is pushed on the four mounting rotating frames 5. After the control rod 14 is pushed, the control rod 14 can push the telescopic rod 13 to rotate, so that the right end of the telescopic rod 13 can be lowered, so that the telescopic rod 13 can drive the sliding block 12 to descend, so that the sliding block 12 can pull the pulling rod 11, and the pulling rod 11 can pull the positioning frame 8 to disengage from the positioning plate 7 to unlock the mounting rotating frame 5, so that the mounting rotating frame 5 can rotate freely. After the ends of the racks 5 that are away from each other are lifted and rotated, the four mounting rotating racks 5 can push the four adjusting push rods 4, so that the four adjusting push rods 4 can push the four mounting rotating racks 5 to be close to each other and fit with the composite cable, so as to limit the position of the composite cable and prevent the composite cable from deviating. After limiting, the sliding unlocking rack 24 is released, so that the sliding unlocking rack 24 can release the positioning rack 8, so that the positioning rack 8 can automatically engage with the positioning disk 7. At this time, the electric conveyor 3 is started again to convey the composite roller to the bottom of the tool 18, and then the electric push rod 16 is started, and the electric push rod 1 6 can push the cutter 18 down to cut the cable stably. If the cutter 18 is used for a long time and needs to be damaged, when the cutter 18 needs to be replaced, it is only necessary to press the two sliding unlocking frames 24 on the left and right sides of the docking sleeve 17. After the sliding unlocking frames 24 are pressed down, the sliding unlocking frames 24 can squeeze the two fitting frames 23 away from each other, so that the two fitting frames 23 can move away from each other, so that the two sliding unlocking frames 24 can drive the two driving rods 21 to move away from each other, so that the two driving rods 21 can drive the two rectangular blocking blocks 20 and When the docking block 19 is disengaged, the docking block 19 and the tool 18 can be unlocked, and the tool 18 can be replaced. After the replacement is completed, the rectangular blocking block 20 is released so that the rectangular blocking block 20 can automatically engage with the docking block 19. After the docking block 19 is engaged with the rectangular blocking block 20, the rectangular blocking block 20 can connect the docking frame with the tool 18 to block the movement of the tool 18 on the docking sleeve 17, so that the tool 18 cannot be detached from the docking sleeve 17, and the tool 18 can be installed and replaced without affecting the cutting of the composite cable.

[0062] The present invention also proposes a cutting method of an optoelectronic composite cable cutting device, comprising the following steps:
