Description

Technical Field

[0001] This utility model relates to the technical field of packaging box production equipment, specifically to an embossing device for producing packaging paper boxes. Background Technology

[0002] A cardboard box is a three-dimensional shape, composed of a number of facets that are moved, stacked, folded, and enclosed. In three-dimensional composition, facets play a role in dividing space. By cutting, rotating, and folding different parts of the facets, a cardboard box is obtained.

[0003] In the typical production process of cardboard packaging, a flat cardboard is pre-produced, and creasing is applied to the areas on the outside of the cardboard where bending is required. This creasing facilitates subsequent folding of the cardboard. The cardboard is usually moved to the lower part of the creasing roller, carried by a conveyor belt, while the creasing roller moves downwards, causing creasing blades mounted on its exterior to press creases of a specific length onto the cardboard. However, when folding the cardboard, creasing is required in both the longitudinal and transverse directions. Therefore, after the creasing roller finishes creasing the cardboard in one direction, the operator needs to manually adjust the cardboard's orientation before creasing can continue in the other direction. Manually adjusting the cardboard's orientation is time-consuming and inefficient. Therefore, we propose a creasing device for cardboard packaging production. Utility Model Content
