Description

Technical Field

[0001] The utility model relates to the field of carton production equipment, in particular to an automatic feeding device for wrinkle-resistant and thickened cardboard. Background Art

[0002] Corrugated cardboard is widely used as the main raw material for carton production because of its high mechanical strength and ability to withstand collisions and falls during transportation. After the corrugated cardboard is produced, it needs to be turned over and printed on the back. However, most of the current corrugated cardboard uses wrinkle-resistant thickened cardboard, which is heavy.

[0003] Currently, there are two general ways to load wrinkle-resistant, thickened cardboard. One is manual, requiring one or two people to carry stacks of paper (i.e., several stacks of cardboard that reach a certain height) in batches to the paper feeder of the printing press. However, the paper feeder is high, making it difficult to carry manually, increasing labor intensity. It is also prone to tipping over during transportation, posing a risk to workers and reducing production reliability. The other is semi-automatic, using a loader to raise the entire stack of paper, which is then manually tipped onto the paper feeder of the printing press. This has a low degree of automation, reducing production efficiency, and the manual tipping process can easily lead to chaotic stacking, reducing production reliability. Utility Model Content
