Description

Technical Field

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

[0002] The conductor materials in waste cables, such as copper and aluminum, are non-renewable resources with high recycling value. In order to remove the conductor materials, the insulation of the cable needs to be stripped off.

[0003] Existing stripping machines typically only cut one side of the cable insulation, meaning the insulation only has a single notch. Removing the conductor requires manual extraction from the insulation. For example, patent publication No. CN218386479U discloses a scrap wire and cable stripping machine capable of stripping multiple cables simultaneously. However, the inventors believe that this machine only cuts one side of the insulation and does not automatically split the insulation.
