Abstract

This invention proposes a conveyor mechanism for processing ultra-wide coated fabrics and its control method. The conveyor mechanism comprises a roller assembly consisting of multiple rollers. Along the conveying direction, the conveyor mechanism is divided into a feed stage, a first-stage lifting stage, an intermediate relaxation stage, an intermediate and later-stage under-relaxation stage, and a final-stage stress release stage. The roller heights in each stage vary according to a piecewise function curve, including a rapid rise, a horizontal stage, a gentle rise, and a slow descent. The roller assembly parameters are configured as follows: during the feed stage, the first-stage roller is aligned with the upstream material feed direction; the final-stage roller has the same diameter as the first-stage roller; the first-stage and secondary rollers are actively driven, with the secondary roller rotating at 0.9 times the speed of the first-stage roller. The intermediate-stage rollers are alternately driven with active and passive drives. The control method includes staged stress control, dynamic parameter adaptation, and forced convection heat transfer control. This conveyor mechanism and its control method can effectively improve coating processing quality, enhance adaptability, optimize temperature control, and increase production efficiency.
