Technical Field

[0001] The invention relates to the technical field of cored wire detection, in particular to a cored wire detection device. Background Art

[0002] Core wire is a composite material used in steelmaking or casting. It is made of alloy powder wrapped in a strip of steel. This material can more effectively add smelting materials into molten steel or molten iron, and insert the core wire into the ideal position through professional wire feeding equipment. When the core wire skin is melted, the wire core can be fully dissolved and chemically reacted in the ideal position, effectively avoiding reactions with air and slag, and improving the absorption rate of smelting materials.

[0003] The existing cored wire inspection work is generally carried out manually. Although this method can ensure a certain inspection quality, the efficiency is relatively low. With the rapid development of the automation industry, the requirements for inspection efficiency are getting higher and higher.

When the equipment starts working, the cored wire reaches the limit disc through the turntable, and the limit disc can adjust and limit the position of the cored wire to ensure that the cored wire is located at the center of the damage detection box. At this time, the cored wire first reaches the limit detection component, enters the cleaning component after being detected by the damage detector, then reaches the repair component, and finally reaches the limit disc at the other end, completing the sorting and collection of the inspected cored wire.
