Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to an automatic cable stripping machine. Background Art

[0002] In order to effectively protect the cable, such as applying special protective materials, it may be necessary to remove part of the outer sheath. Secondly, when connecting the cable to equipment, electrical boxes, etc., the outer sheath must be peeled off to expose the internal conductors, such as copper wires or aluminum wires, so as to achieve a good electrical connection and ensure the stable transmission of electricity. Furthermore, when it is necessary to check whether there are faults such as short circuits and open circuits inside the cable, or to repair damaged parts, the peeling operation is essential. Finally, in the process of recycling waste cables, peeling can separate valuable metal parts, such as copper, from the outer sheath so that they can be recycled and reused separately.

[0003] When connecting cables, electricians will use electrician's knives to peel off the outer sheath of the cable. When operating the knife to cut the cable, uneven force will occur, which will scratch the outer sheath of the inner core of the cable, causing insulation degradation and creating safety hazards. In addition, it is very easy to scratch the arm when using an electrician's knife, causing personal injury. Therefore, in response to the above phenomenon, an automatic cable peeling machine is proposed, which can save labor and reduce the labor intensity of electricians. Utility Model Content
