Background technique

Corrugated cardboard is made of top paper, lining paper, core paper and corrugated paper processed into corrugated corrugated sheets through bonding. According to the needs of product packaging, corrugated cardboard can be processed into single-sided corrugated cardboard, three-layer corrugated cardboard, five-layer, seven-layer, eleven-layer and other corrugated cardboard. Single-sided corrugated cardboard is generally used as a lining protective layer for commodity packaging or to make lightweight frames and pads to protect commodities from vibration or collision during storage, transportation, and three-layer and five-layer corrugated cardboard are used in making corrugated boxes. common. Many products are packaged simply and beautifully using three- or five-layer corrugated cardboard. Beautiful and colorful graphics and pictures are printed on the surface of corrugated boxes or corrugated boxes, which not only protects the inner goods, but also promotes and beautifies the inner goods. commodity. Many corrugated boxes or corrugated boxes made of three-layer or five-layer corrugated cardboard have been directly put on the sales counter and become sales packaging. Seven-layer or eleven-layer corrugated cardboard is mainly used to make packaging boxes for mechanical and electrical appliances, flue-cured tobacco, furniture, motorcycles, large household appliances, etc. For specific products, this combination of corrugated cardboard can be used to make inner and outer boxes, which is convenient for production and convenient for the packaging, storage and transportation of the products. With the need for environmental protection, commodity packaging made of corrugated cardboard has a tendency to gradually replace wooden box packaging.

In the Chinese patent number CN213261340U, a creasing device for a corrugated carton slitting and creasing machine is disclosed. When using this device, first, place the corrugated carton on the workbench, and then according to the size of the corrugated carton that needs to be processed , through the cooperation of the second limit hole and the first limit hole on the adjustment guide plate, the distance between the positioning guide plate and the adjustment guide plate is adjusted to adapt to the size of the corrugated carton, and the corrugated carton is placed on the adjustment guide plate and the positioning guide plate, then start the power supply, and control the expansion and contraction of the second piston rod through the second cylinder to control the push plate to push the corrugated carton between the upper and lower pressing wheels for indentation. Through the first motor and The rotation of the second motor drives the rotation of the first rotating rod and the second rotating rod, thereby driving the rotation of the upper pressing wheel and the lower pressing wheel. The upper pressing wheel and the lower pressing wheel are respectively provided with pressure strips and pressure grooves. Through the pressure strips and pressure grooves, The grooves are matched to indent the corrugated carton, and the first cylinder is used to control the expansion and contraction of the first piston rod, and the knife holder and the blade are controlled to press down to slit the corrugated carton. There is a knife groove on the workbench, and the knife groove is used during slitting. It is used to accommodate the blade to facilitate the blade to slit the corrugated carton.

At present, the creasing device of the corrugated carton slitting and creasing machine published in the above patent has certain technical shortcomings:

1. The distance between the adjacent upper pressing wheel and the adjacent lower pressing wheel cannot be changed, and the indentation spacing cannot be adjusted according to different corrugated cartons. According to the needs of different corrugated cartons, the first rotating rod and the upper pressing wheel need to be replaced. The second rotating lever and lower pressure wheel are very inconvenient and are not conducive to quick switching, which limits work efficiency;

2. During the cutting process, use the blade to press down into the slot to cut the corrugated paper. The contact between the blade and the slot will easily cause increased wear of the blade and shorten the service life of the blade.
