A multi-head steel strip winding control system

This invention provides a multi-head steel strip winding control system, including a main channel with multiple winding stations equipped with winding wheels along its length. The steel strip moves along the main channel, arranged from the outside to the inside and sequentially wound onto the winding wheels at each winding station. A redundant steel strip detection unit detects the amount of steel strip redundancy. When the redundancy exceeds a maximum redundancy threshold, the winding wheel speed is increased until the redundancy falls below a minimum redundancy threshold, at which point the speed is reduced back to the initial speed. As the steel strip passes through the main channel, it is wound directly onto multiple winding wheels in an outward-to-inward sequence, eliminating the need for rewinding via a rewinding machine and then rewinding via a layer winding machine, thus shortening production steps. Simultaneously, it keeps the steel strip in a relaxed state during winding, preventing excessively long redundant steel strips from drooping and contacting the ground, which could cause multiple narrow steel strips to knot or rub against the ground, affecting continuous production and product quality.
