Adjust the height, spacing, and position of the paper receiving stack according to the size and stacking requirements of the die-cut products to ensure that the cardboard can be stacked neatly and stably on the paper receiving stack. Feed the cardboard into the die-cutting machine for die-cutting. During the die-cutting process, pay attention to the movement of the cardboard in the die-cutting section to ensure the die-cutting quality. After the cardboard is die-cut, it is transported to the paper receiving stack by the conveyor device. During the paper receiving process, the operator needs to constantly observe the status of the paper receiving stack to ensure that the cardboard is stacked neatly and stably, and adjust the height and position of the paper receiving stack in a timely manner.
