Description

Technical Field

[0001] The utility model relates to the technical field of paperboard production, in particular to a pneumatic paper pressing mechanism device. Background Art

[0002] Cardboard, also known as paperboard, is a thick paper sheet made of various pulps and interwoven with fibers. The difference between cardboard and paper is usually distinguished by basis weight and thickness. Generally, paper with a basis weight of more than 250g / ㎡ and a thickness of more than 0.5mm is called cardboard (another way of saying it: paper with a thickness of more than 0.1mm is generally called cardboard. Generally, paper with a basis weight of less than 250g / ㎡ is considered paper, and paper with a basis weight of 250g / ㎡ or more is considered cardboard). During the cardboard processing process, a paper pressing mechanism is required to press it. During the use of the paper pressing mechanism, dust and glue will remain on the support plate used to support the cardboard, affecting the extrusion of the cardboard. Therefore, a pneumatic paper pressing mechanism device is proposed to facilitate the cleaning of dust and glue. Utility Model Content
