Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper, and particularly relates to a corrugated paper defect trimming machine. Background Art

[0002] Corrugated paper is a plate-shaped object formed by bonding a facing paper and a corrugated paper with a waveform formed by processing through a corrugating roll. It is generally divided into two categories: single corrugated cardboard and double corrugated cardboard. During the use of corrugated paper, due to reasons such as storage, the stored corrugated paper may have parts that are bent, affected by moisture and moldy, or damaged by insects. During use, the defective parts need to be trimmed to ensure the clean appearance of the packaged items.
