Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboard processing equipment, in particular to a corrugated paperboard pressing mechanism. Background Art

[0002] At present, corrugated cardboard is composed of layers of wavy core paper and cardboard. It has high mechanical strength and can withstand collisions and falls during transportation. It is mainly used to make cartons. In the process of making cartons, it is usually necessary to use a corrugated cardboard printing and slotting machine to print, slot and crimp the corrugated cardboard.

[0003] The corrugated cardboard creasing mechanism is usually used to creasing the corrugated cardboard. The existing corrugated cardboard creasing mechanism includes a frame, an upper creasing roller, a support roller, a creasing ring, a support ring and a driving mechanism capable of driving the upper creasing roller and the support roller. The driving mechanism is installed on the frame. The upper creasing roller and the support roller can be rotatably installed on the frame and arranged side by side up and down. The creasing ring is mounted on the upper creasing roller and can move on the upper creasing roller. The support ring is mounted on the support roller and can move on the support roller. The creasing ring and the support ring are matched up and down. The creasing ring is provided with a convex ring, and the support ring is provided with an annular groove matching the convex ring. When working, the corrugated cardboard is passed between the creasing ring and the support ring piece by piece, and the corrugated cardboard is creasing through the cooperation of the convex ring and the annular groove. Since the outer peripheral surfaces of the creasing ring and the support ring are made of hard materials, when creasing, the outer peripheral surfaces of the creasing ring and the support ring are easy to exert excessive pressure on the corrugated cardboard, which is easy to cause excessive deformation of the corrugated cardboard's corrugated core paper, and even breakage or collapse. Utility Model Content

[0004] The problem to be solved by the utility model is to provide a corrugated board creasing mechanism, which can effectively buffer the pressure applied during the creasing process to avoid excessive deformation, breakage or collapse of the corrugated board.
