Description

Paper collecting device and method capable of stacking papers on the front and back

The invention relates to a paper turning machine, in particular to a paper collecting device and a method for stacking papers which can be rotated and lifted at the same time to stack the front and back sides of the cardboard to prevent the paperboard from being bent.

During the manufacture and transportation of paper, the paper must be adjusted to maintain the consistency of the paper. Usually, the paper is guided by the guides on both sides during the conveyance process, but the normal state of both sides of the paper after the guide is slightly bent. Furthermore, after the paper is continuously conveyed and stacked, if the middle of the paper is uneven, the paper stacked on the opposite side tends to be bent on both sides, and when the thickness of the paper is thick, it is necessary to return to the original shape after bending. It takes a while to get to the sides with considerable power. In view of this, the manufacturer reverses the paper during the paper conveying process, and the paper sheets are stacked on each other on the front and back sides to solve the problem that the sides of the paper are bent after the sheets are stacked on one side.
