Description

Multilayer pressing device for corrugated board Technical Field The utility model relates to the technical field of corrugated board multilayer lamination, in particular to a corrugated board multilayer lamination device. Background The corrugated board is a multi-layer paper board, which is formed by combining one or more layers of corrugated medium paper with one or more layers of flat paper (face paper and inner paper) through the processes of glue bonding, pressing and the like, and the special structure ensures that the corrugated board has good buffering performance, compressive strength and stiffness, is a main material for manufacturing packaging containers (such as cartons and cartons), and is required to be pressed and formed by using a corrugated board multi-layer pressing device before being manufactured into the packaging containers, and the corrugated board multi-layer pressing device is equipment for tightly adhering the multi-layer corrugated board materials together in a pressure applying mode, is one of key equipment in the corrugated board production process, and can ensure the structural strength and stability of the corrugated board.
