AI Technical Summary
Traditional honeycomb paper cores have difficulty in quickly expelling heat and moisture during the lamination process, which causes the honeycomb paperboard to bubble. Furthermore, existing lamination methods increase costs and the risk of damaging the paper core.
The paper core forming mechanism uses corrugated blades to cut paper core strips by horizontally floating corrugated blades, making the end face a horizontal composite surface with venting grooves, forming a longitudinal venting channel to ensure that hot and humid air is quickly discharged and to prevent bubbling.
It improves the drying efficiency and quality of honeycomb paperboard, avoids paperboard bubbling, and reduces the lamination length and cost of the equipment.
