Description

Technical Field

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

[0002] At present, cables are made of one or more mutually insulated conductors and an outer insulating protective layer, which is also called a cable sheath. There are great differences in the quality of cables, which requires the inspection of finished cables, stripping of a large number of cable sheaths, and then various tests on the cable cores. Existing peeling sheath stripping equipment is designed for recycling waste cables or for electricians. The focus is on stripping the cable sheath without providing more protection for the cable core. The depth of the sheath cut is not precisely controlled, and the cable sheath has a certain elasticity. When the cable is cut by the cutting knife, it is compressed and deformed to a certain extent. Due to these deformations, the sheath cannot be cut or cut too much, and whether the cable core is intact will affect the inspection test results. If the cable sheath stripping work is replaced by manual work, the existing equipment is inefficient and will also damage the cable, and the core cannot guarantee the integrity of the cable core.
