Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboard processing, in particular to a thin-knife longitudinal cutting and creasing machine for processing corrugated paperboard. Background Art

[0002] Corrugated board is a paper board made of corrugated paper, usually used for packaging and protecting items. It consists of one or more layers of corrugated paper and face paper. Corrugated paper is a material composed of longitudinal raised corrugations (also called corrugated core) and smooth face paper on both sides. The raised corrugations of corrugated paper form a series of hollow gaps, which can increase the strength and cushioning performance of the board. Corrugated board usually has the characteristics of light weight, high strength and good flexibility. It is widely used in various packaging fields, such as cartons, paper boxes, paper tubes, paper pallets, etc. Corrugated board can meet different packaging needs according to different thickness, paper quality and corrugated form. It can effectively protect items from external impact and extrusion, and reduce the risk of damage during transportation and storage.

[0003] In the production process of corrugated cardboard, commonly used equipment includes corrugated cardboard production lines, longitudinal cutting and creasing machines, gluing machines, etc. These equipment can cut, crimp, and gluing corrugated cardboard to meet different packaging needs and specifications.

[0004] According to the "Thin-knife longitudinal cutting and creasing machine for corrugated cardboard processing" proposed in CN 218532072 U, the device includes a device main body; the telescopic effect of the second electric telescopic rod enables the height of the pressing plate to be adjusted, so that the pressing plate can limit the corrugated cardboard of different thicknesses, ensuring that the corrugated cardboard will not tilt up during the creasing process, and the telescopic effect of the third electric telescopic rod enables the horizontal position of the pressing plate to be adjusted, so that it can be suitable for corrugated cardboard with different creasing positions; the telescopic effect of the fourth electric telescopic rod enables the position of the creasing wheel to be adjusted left and right, so that the creasing wheel can be aligned with the creasing groove, and the telescopic effect of the sixth electric telescopic rod enables the position of the creasing wheel to be lowered, so that the creasing wheel can enter the creasing groove and contact the corrugated cardboard, and then through the action of the fifth electric telescopic rod, the creasing wheel can move along the direction of the creasing groove, thereby completing the creasing operation of the corrugated cardboard.

[0005] Although the above-mentioned thin-blade longitudinal cutting and creasing machine can limit corrugated cardboards of different thicknesses through the pressing plate to ensure that the corrugated cardboard will not warp up during the creasing process, the creasing wheel needs to be aligned with the creasing groove of the pressing plate each time the operation is performed, which makes the operation troublesome and is not convenient for continuous loading and processing, affecting work efficiency.

[0006] Therefore, we propose a thin-knife slitting and creasing machine for corrugated board processing to solve the problems in the above background. Utility Model Content
