Description

Technical Field

[0001] The present application relates to the technical field of carton sealing, and in particular to an automatic carton sealing machine. Background Art

[0002] In the packaging industry, the sealing of books, cartons and other items has always been an important link. Traditionally, this link mainly relies on manual operation, which is not only inefficient but also has high labor costs. With the rapid development of automation technology, automatic carton sealing machines are gradually applied to this field, greatly improving the efficiency of carton sealing operations and reducing labor costs.

[0003] Most of the current carton sealing machines are mainly composed of a conveying mechanism and a tape carton sealing mechanism. The conveying mechanism transports the carton loaded with products to the tape carton sealing mechanism, and then the tape carton sealing mechanism automatically seals the carton.

[0004] The folding flaps on both sides of the carton are aligned, and then the tape sealing mechanism sticks the tape on the aligned parts of the two folding flaps, and finally the tape is cut, thereby sealing the carton in a straight-line pasting manner. The straight-line pasting manner reduces the contact area between the tape and the carton, reduces the adhesion between the tape and the carton, and makes the tape easy to peel off when subjected to external force, resulting in the defect of poor sealing firmness. Utility Model Content
