AI Technical Summary
During the production of 1+6 structure steel cord, vibration of the wire feeding equipment can cause uneven tension of the steel wire, affecting the twisting quality and potentially leading to problems such as uneven twisting, exposed core, and bubbling.
A steel cord tension adjustment device is adopted, which uses a combination of guide crank, passive slider, curved sleeve spring and servo motor to achieve elastic guidance and uniform tension adjustment of steel cord, avoiding excessive looseness or tightness.
It effectively reduces steel cord loss and breakage, improves production efficiency, ensures uniform tension of steel cord, and enhances product quality.
