Description

Technical Field

[0001] The present application relates to the technical field of cardboard processing, and in particular to a cardboard cross-cutting device. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper (commonly known as "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and one layer of cardboard (also known as "boxboard", "boxboard"). The existing corrugated cardboard production line generally includes base paper racks, glue coating machines, double-sided machines, longitudinal cutting and creasing machines, cross-cutting machines, stacking machines and other equipment; At present, some cross-cutting machines are usually only equipped with a set of cutting devices. When the cardboard moves along the conveyor belt, the cutting device moves at the same speed as the cardboard according to the cardboard length set by the user, and uses the cutting blade to perform rapid horizontal cutting. After cutting, the cutting device needs a certain time to reset, and then continues to cut the cardboard. Since the cutting device needs to be reset, the cardboard continues to move during the reset process. If you want to cut a shorter cardboard, you need to reduce the conveyor belt running speed to reduce the moving distance of the cardboard, leaving enough time for the reset of the cutting device to cut, thereby achieving cutting of several shorter cardboards. However, when production efficiency needs to be improved, it is necessary to increase the conveyor belt running speed so that the cutting device can cut more cardboards. Since the above-mentioned cutting device needs to leave enough time to reset, it cannot reciprocate with the cardboard moving faster, resulting in the inability to improve production efficiency. Therefore, further improvements can be made. Summary of the invention

[0045] The implementation principle of a cardboard cross-cutting device in an embodiment of the present application is as follows: when it is necessary to efficiently produce cardboard of shorter length, the conveying mechanism 2 increases the running speed of the cardboard, so that the running speed of the cardboard is accelerated, and the two groups of cutting mechanisms 3 cut the cardboard synchronously. After the first cutting, the two groups of cardboard are reset. During the resetting process, the cardboard is quickly transported forward, and the first group of cutting mechanisms 3 is reset to the position of the second group of cutting mechanisms 3 at the time of the first cutting. The second group of cutting mechanisms 3 is reset to its own position at the time of the first cutting and retreats one position, and performs the second cutting. After the second cutting is completed, the first group of cutting mechanisms 3 is reset to its own position at the time of the second cutting and advances one position. The second group of cutting mechanisms 3 is reset to the position of the first group of cutting mechanisms 3, and performs the third cutting. Thereafter, the resetting and cutting are repeated in this way, thereby achieving the improvement of the cutting processing efficiency of the cardboard of shorter length while the running speed of the cardboard is accelerated.
