Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to a cable sheath cutting device. Background Art

[0002] The shielding layer materials of shielded network cables are mainly aluminum foil and braided mesh. Braided mesh is generally woven from tinned round copper wires, mainly to prevent low-frequency electromagnetic wave interference; while aluminum foil is mainly used to shield high-frequency electromagnetic waves, preventing high-frequency electromagnetic waves from contacting the network cable conductors and generating induced currents, increasing crosstalk. When processing cables containing aluminum foil, it is necessary to first peel off the aluminum foil layer from the cable. In the prior art, the peeling of the aluminum foil layer is mostly done manually. Since the aluminum foil layer is relatively thin, when the aluminum foil layer is cut with a blade, if the blade contacts the cable, it is easy to cause damage to the cables inside the aluminum foil layer. Therefore, a half-cut method is often used, that is, the blade only cuts a part of the aluminum foil layer, not the bottom of the aluminum foil layer, and then the blade is rotated for cutting. Manual cutting requires the use of a blade, which poses a safety hazard and has low processing efficiency. A device that can cooperate with the automated production of shielded cables is required, and will not damage the cables inside the aluminum foil layer. Utility Model Content
