Description

technical field [0001] The invention belongs to the field of box sealing equipment for a box sealing machine, in particular to a box sealing device of a fully automatic box sealing machine. Background technique [0002] The carton sealing machine is mainly suitable for carton sealing and packaging. It can be used as a stand-alone machine or with an assembly line. It can be used for single-carton operation, and it can also be used with carton forming and unpacking machines, carton packing machines, labeling machines, strapping machines, Pallet stackers, conveyors and other equipment are used in a packaging line and are necessary equipment for packaging line operations. The demand for various sizes of cartons makes people have higher requirements for the versatility of the carton sealing machine. That is to say, cartons of different sizes can be sealed by the same sealing machine. Therefore, the multi-purpose sealing machine has been sought after by everyone. [0003] Exist...

AI Technical Summary

Problems solved by technology

Although the existing carton sealing machine can seal cartons of different sizes, it is necessary to align the sealing of the carton with the center of the tape during the sealing process, so that the carton can be sealed firmly. The positioning of the carton in the existing carton sealing machine is not good, resulting in asymmetry between the tape and the carton seal, and the seal is not firm, and manual alignment is usually required

At the same time, when sealing the carton, it is often difficult to align the seal of the carton with the center of the tape, and the carton paper at the seal of the carton is usually tilted, which brings difficulties to the sealing of the tape
