Description

Technical Field

[0001] The invention relates to an indentation making device, in particular to a bottom pad. Background Art

[0002] With the rapid development of the printing and packaging industry, the market demands increasingly higher levels of automation for post-press processing equipment. The pursuit of high-speed, precise processing equipment to improve production efficiency and capture market share is a market demand and an inevitable trend in the development of post-press equipment. The indentation device is a specialized device used for indenting paper, cardboard, and corrugated paper in the printing, packaging, and decoration industries.

[0003] Existing indentation devices typically consist of a blade and a base plate. During indentation, the blade presses down, and the indenting blade on the blade applies pressure to the paper, creating the indentation. Once the indentation is complete, the paper is transported out of the indentation device for further processing. In practice, because the indentation requires significant pressure on the paper, the pressure can easily cause the paper to adhere to the base plate. This adhesion can prevent the indented paper from being transported out of the indentation device in a timely manner, causing paper jams and impacting production efficiency.
