Cable extruded insulation online detection marking system

Abstract

The invention discloses a cable extruded insulation online detection marking system. The system comprises an insulation detection sleeve ring and an abnormal marking ink spraying nozzle which are sequentially arranged from top to bottom on a production line, several insulation detection probes are arranged at the inner side of the insulation detection sleeve ring, and each insulation detection probe is arranged in the radial direction of the insulation detection sleeve ring; the insulation detection probes are circumferentially distributed along the axis of the insulation detection sleeve ringat equal intervals, and the abnormal marking ink spraying nozzle can spray out ink for marking simply through conductive electric connection between every two adjacent insulation detection probes. Bymeans of the cable extruded insulation online detection marking system, the two ends of a power cable do not need to be powered on, and thus insulation detection work can be carried out on an insulation extruding line to improve the efficiency of power cable insulation detection work.

Description

technical field [0001] The invention relates to the technical field of cable processing technology and equipment, in particular to an on-line detection and marking system for cable extrusion insulation. Background technique [0002] Most of the cable insulation layer is processed by the extrusion process, that is, the polymer material with good electrical insulation performance is heated and melted, and then extruded and wrapped on the outside of the cable conductor core; during the extrusion process, due to the cable conductor wire The core is not coaxial with the extrusion die, or the cable conductor core is bent in the extrusion die due to insufficient tension of the cable conductor core, which will result in incomplete wrapping of the cable conductor core by the extruded cable insulation layer; and extrusion The cable insulation layer will also be damaged due to equipment scratches in the subsequent processing steps. The damaged cable insulation layer will lead to risks ...

Problems solved by technology

[0002] Most of the cable insulation layer is processed by the extrusion process, that is, the polymer material with good electrical insulation performance is heated and melted, and then extruded and wrapped on the outside of the cable conductor core; during the extrusion process, due to the cable conductor wire The core is not coaxial with the extrusion die, or the cable conductor core is bent in the extrusion die due to insufficient tension of the cable conductor core, which will result in incomplete wrapping of the cable conductor core by the extruded cable insulation layer; and extrusion The cable insulation layer will also be damaged due to equipment scratches in the subsequent processing procedures. The damaged cable insulation layer will lead to risks such as short circuit and electric leakage during the use of cable products.

[0003] The power cable insulation detection in the prior art mainly adopts the live detection method, that is, both ends of the power cable to be tested need to be connected to electricity, and then the detection device is used to detect from one end of the power cable to the other end. When a certain section of the power cable insulation is damaged , the power supply of the power cable and the detection device form a loop, thereby triggering the detection device to alarm; the above detection method is cumbersome to operate and has low work efficiency
