working principle:

   The paper feeding mechanism takes the pre-printed and cut cardboard sheets from the paper tray to the conveyor chain, and then sends them to the forming mold. In the process, the paper sheets are coated with water-based glue (or hot melt). Glue), the position of the glue can be adjusted at will, the coating amount of the glue can be adjusted in the production without stopping the machine. The coated cardboard pieces are sent to the collector after forming, automatically stacked and counted, and are scheduled. The number of stacks is automatically marked without downtime.
