Description

Technical Field

[0001] The present application relates to the field of carton manufacturing technology, and in particular to an anti-blocking paper knife support structure. Background Art

[0002] Cardboard boxes are commonly used packaging materials in people's daily lives. When producing cardboard boxes, cardboards of corresponding sizes need to be manufactured and then assembled into cartons.

[0003] To meet the production needs of cartons of varying sizes, the edges (ears) of the cardboard need to be cut after it is manufactured. During the cutting process, it was discovered that the cardboard could fold during transportation on the production line, resulting in excessive thickness. The gap between the knife support and the machine was not wide enough for the cardboard to pass through, causing paper jams, causing the production line to stop and causing certain losses. This needs to be improved. Utility Model Content
