Background
The belt conveyor is the most widely used transport machine in industrial production. The steel cord conveyor belt uses a steel cord liner covered with a rubber conveyor belt as a traction and carrying member of a belt conveyor. The steel rope core conveyer belt has the characteristics that: the high-strength high-flexibility conveying belt has the advantages of high tensile strength, good impact resistance, long service life, small service elongation, good grooving property and good bending resistance, and is suitable for conveying materials at long distance, long distance and high speed. The product is composed of core glue, steel wire ropes, covering layers and edge glue. In production, sometimes, after the steel ropes in the conveyer belt are broken, the steel ropes gradually pierce through a covering layer (generally an upper covering layer of a bearing surface) to expose the surface of the covering layer, and the exposed length is gradually longer and longer as time goes on, and when the steel ropes reach a certain length, the steel ropes are easily wound on a carrier roller, a roller funnel and other members of a belt conveyer, the steel ropes are drawn out, the conveyer belt is longitudinally broken from a drawing-out line, huge economic loss is caused, and production stop and repair are needed.
In order to detect a steel cord break at an early stage, several detection devices are applied: 1) and a magnetic field detection method in which a magnetic field is applied to the belt and a change in the magnetic field is detected. When the broken steel rope passes through the detection magnetic field, the magnetic field changes, and the device analyzes and processes the changed signal and sends out an alarm signal.
