[0027] During operation, the cable is wound on the pay-off roller 10, and the cable on the pay-off roller 10 is inserted through the bottom of the guide roller 11. Then, the cable extending from the guide roller 11 is inserted between the two limiting wheels 8. The cable passes through the limiting wheel 8 to ensure the stability of the cable transportation. The cable passing through the limiting wheel 8 is stripped by the cutting knife 25, and the cutting knife 25 mainly divides the cable into two parts: a core and a sheath. The core is finally rolled up on the take-up roller 12, and the sheath is rolled up on the recovery roller 13. During the stripping process, a large amount of fillers are wrapped in the cable.

[0037] During operation, when cutting is required, the electric push rod 7 is turned on, and the electric push rod 7 pushes the telescopic cylinder 24 downward through the output end. During the downward movement of the telescopic cylinder 24, the cutting knife 25 and the spring 26 are driven to move downward. When the cutting knife 25 is cutting, the spring 26 has a buffering effect to prevent the cutting knife 25 from cutting deeply into the wire core and damaging the wire core.

The cable passes through the limiting wheels 8 to ensure the stability of the cable transportation. The cable passing through the limiting wheels 8 is stripped by the cutting knife 25, and the cutting knife 25 mainly divides the cable into two parts: the core and the sheath. The core is finally rolled up on the take-up roller 12, and the sheath is rolled up on the recovery roller 13. During the stripping process, a lot of fillers are wrapped in the cable. During the stripping process, some of the fillers fall and need to be collected and cleaned. In order to solve the problem of quickly cleaning the fillers in the cable, it is necessary to turn on the fan 3. Under the action of the fan 3, the wind enters the dust hood 5 through the dust suction pipe 4. The dust suction hood 5 is opposite to the cutting knife 25. The dust suction hood 5 absorbs the fillers, and the fillers enter the dust collecting box 2 through the dust suction pipe 4. , with the cooperation of the fan 3, the dust hood 5 and the dust pipe 4, the function of quickly cleaning the filler is realized; the sizes of the cables are different.
