Description

[0002] With the increasing demand for electricity in modern industry and residents' lives, wires and cables, as important carriers of power transmission and distribution, have a quality that is directly related to the safe and stable operation of the power system. In the production process of wires and cables, the thickness of the cable insulation sheath is a crucial parameter. It not only affects the insulation performance of the cable, but is also directly related to the durability and safety of the cable. Therefore, accurate measurement of the thickness of the cable insulation sheath is a key step to ensure the quality and performance of the cable.

These methods are not only time-consuming and laborious, but also due to the influence of human factors, the accuracy and consistency of the measurement results are often difficult to guarantee. In addition, the pressure plate pressing method is usually simple and rough, which may cause the sheath to deform too quickly, resulting in sheath damage and lack of secondary extrusion. Therefore, a flattening mechanism for cable insulation sheath thickness measurement is needed to solve the existing shortcomings. Utility Model Content
