Cable damage detection device

Abstract

The invention discloses a cable damage detection device. One end of a rack is provided with an elastic expansion assembly, the elastic expansion assembly is sleeved with a pressure sensing assembly, an ink jet system is arranged above the outer side of the elastic expansion assembly, the ink jet system and the pressure sensing assembly are both electrically connected with a PLC, the other end of the rack is provided with a thermal straightening assembly, the thermal straightening assembly and the elastic expansion assembly are coaxially arranged, when a bulge bulge penetrates through the elastic expansion assembly, the elastic expansion assembly elastically presses the pressure sensing assembly to generate a pressure signal, the signal is transmitted into the PLC and controls the ink jet system to mark at the bulge bulge, and the thermal straightening assembly straightens a cable and then sends the cable into the elastic expansion assembly. The cable damage detection device can continuously detect the flatness of a surface insulation layer of a cable, when a bulge on the surface of the cable passes through a narrow opening formed by an arc-shaped elastic piece, the bulge position is effectively sprayed and marked, the bulge position is uniformly processed after marking, and the cable detection efficiency is high.

Description

technical field [0001] The invention relates to the field of cable damage detection, in particular to a cable damage detection device. Background technique [0002] Since the extrusion temperature, extrusion speed and crosslinking speed of silane crosslinked cable materials of different manufacturers are not the same, it is inevitable that there will be appearance quality problems in the production process of insulated cables. Quality problems include surface unevenness, bulging etc. These problems are mainly due to the phenomenon of raw rubber in the production process, also known as insulation block or hard block, which causes uneven hard blocks on the surface of the insulated wire core, or mixes old rubber particles in the insulating layer, causing the insulating layer to appear. Uneven, and the appearance of these protrusions represents the unevenness and difference in the density and insulation performance of the insulating layer. During later use, damage and aging are ...

AI Technical Summary

Problems solved by technology

[0003] The existing cable surface protrusion detection device needs to straighten the cable and use ultrasonic or laser to detect the flatness. Since the two ends of the cable need to be fixed and straightened, continuous detection of the cable cannot be performed, which affects the efficiency and speed of detection.
