[0002] In the field of wire and cable processing, longitudinal insulation cutting is an important process that not only affects the efficiency of subsequent cable processing but also directly relates to the overall quality of cable products. In recent years, with the continuous advancement of technology, longitudinal insulation cutting devices for wires and cables have also been significantly improved and innovated. In the production and processing of wires and cables, precise cutting of the insulation layer is one of the key steps to ensure cable performance and quality. It not only affects the overall quality of the cable but also directly relates to production efficiency and safety.
[0003] In the production and repair of wires and cables, longitudinal cutting of the insulation layer is a common operation. However, this process often generates a large amount of dust. Dust not only harms the health of operators but may also adversely affect the insulation performance of wires and cables, and even lead to safety hazards such as short circuits. At the same time, different specifications and materials of wires and cables have different requirements for cutting equipment. However, existing cutting equipment can often only adapt to a certain range of cable specifications. For cables outside the range, it is difficult to guarantee the cutting effect. This not only limits the flexibility of the production line but also increases production costs. Utility Model Content
