Description

Technical Field

[0001] The utility model relates to a rope cutting mechanism, in particular to a rope cutting and box loading mechanism of a fully automatic box opening machine. Background Art

[0002] The carton opening machine (automatic carton forming and bottom sealing machine) is an assembly line equipment that can automatically open large quantities of cardboard into boxes, fold the lower cover, and seal the lower bottom continuously, completing the packaging processes of carton suction, opening, forming, bottom folding, and bottom sealing at one time.

[0003] Before being folded, cartons are in the form of sheets of cardboard, which are usually stacked together and tied together with strapping tape to form a batch for easy transportation. In the prior art, it is necessary to manually remove the strapping tape of each batch of cardboard and then move the cardboard to the box storage of the carton opener. Since the box storage of the carton opener can only store 50 to 70 cartons at a time, in order to ensure the continuous supply of materials, the carton opener needs to be equipped with personnel specifically responsible for loading cartons, which is not only labor-intensive and inefficient, but also brings safety hazards.

[0004] With the changes in the labor market in recent years, the supply of human resources for heavy physical labor has gradually decreased. The use of the rope cutting mechanism of the carton opener has alleviated the problem of labor shortage in various factories, while also reducing the management burden and improving the corporate image and management level.
