AI Technical Summary
Existing ironing devices are prone to damaging laminated packaging boxes when pushing the hot platen, and the cylinder stroke is inconvenient to adjust, and the unstable air pressure leads to low ironing efficiency.
By employing a drive mechanism, a crank-slider mechanism, and a hot-pressing mechanism, combined with positioning, correction, and position sensors, the system enables continuous pushing and uninterrupted ironing of the laminated packaging box. The combination of springs and heating elements provides a stable ironing force.
It enables continuous pushing and uninterrupted ironing of laminated packaging boxes, improving ironing efficiency and avoiding the waiting time required for cylinder ejection and release, thus ensuring efficient and smooth ironing operations.
