Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper production, in particular to a trimming device for corrugated base paper. Background Art

[0002] Corrugated cardboard is a composite cardboard formed by gluing corrugated paper and corrugated paper. It is popular in the packaging industry because of its low price, easy production, and recyclability. During the production process of corrugated paper, due to the specifications of the base paper, when processing according to specific products, the corrugated base paper needs to be cut into appropriate sizes.

[0003] At present, when cutting corrugated paper, the existing cutting equipment needs to take out the cut cardboard after cutting the corrugated paper and then perform the next cutting. The processing action rhythm is large, resulting in reduced efficiency. At the same time, the cardboard needs to be discharged from the inside of the cutting equipment before it can be taken out manually, which is relatively cumbersome in actual application.
