On-line detection system for enameled wire surface paint film thickness

Abstract

The invention belongs to the field of stable enameling film thickness detecting and alarming of the enamelled wire production and particularly relates to an enamelled wire surface enameling film thickness online detection system. The system comprises a discharging component, a detection acquiring component which is used for discharging to an enamelled wire and acquiring the grounded voltage and a control alarming component, and the control alarming component is used for comparing the acquired signals and alarming when the acquired voltage drop is higher than a preset voltage drop constantly in a determined period; the detection acquiring component at least comprises a wire pressing wheel portion, and a concave wheel groove is formed in the edge of the wire pressing wheel portion annularly; a voltage sampling circuit is arranged at a frame of an enameling machine provided with a grounded end; the wire pressing wheel portion comprises upper and lower wire pressing wheels with axle arranged horizontally, and the upper and lower wire pressing wheels are arranged on two sides of the advancing direction of the enamelled wire and are arranged in the advancing direction of the enamelled wire sequentially. The system has the advantages that the detecting efficiency is high, and the system is capable of implementing online accurate detection of the enamelled wire accurately in the high speed advancing process of the enamelled wire.

Description

technical field [0001] The invention belongs to the field of stable detection and alarm of paint film thickness in enameled wire production, and in particular relates to an online detection system for paint film thickness on the surface of enameled wire. Background technique [0002] At present, the competition in the enameled wire market is becoming more and more fierce, and product quality is becoming more and more important. In the enameled wire production process, due to the influence of the production process and other factors, there will usually be discontinuity in the enameled wire paint film, also known as paint film defects, which will have a negative impact on the insulation performance of the enameled wire. In production, the paint film continuity of the enameled wire is mainly detected by off-line detection methods, such as the low-pressure mercury method and the low-voltage electrolyte method. However, in the above-mentioned solutions, regardless of the defects...

Problems solved by technology

However, in the above-mentioned solutions, regardless of the defects of additional operating procedures and increased production costs caused by off-line detection after production, the mercury pollution of the low-pressure mercury method itself, the limited detection capability of the low-voltage electrolysis method and the need to rely on The harshness of the detection conditions brought about by a certain concentration of the solution is a major shackle that affects its popularity.
