Description

Technical Field

[0001] This utility model relates to the field of packaging machines, specifically to a fully automatic side sealing machine. Background Technology

[0002] A shrink-wrapping machine is an indispensable part of a heat-shrink film packaging production line. It's used to package goods before shipment, heat-seal and cut them, and then heat-seal the outer layer of the goods to prevent damage during transportation, storage, and sales. Additionally, when shipping seafood or chilled goods, foam boxes are often used, and an extra layer of film is usually sealed around the outside to make the products look more hygienic and attractive, while also preventing leaks.

[0003] Chinese utility model patent with announcement number "CN213736002U" discloses a fully automatic heat shrink film packaging production line sealing and cutting machine, including a packaging frame, a film feeding device, a sealing and cutting device, a first conveyor belt and a second conveyor belt. The sealing and cutting device includes a rear sealing assembly and a side sealing assembly. The rear sealing assembly includes a cutter holder, a cutter seat and a sealing and cutting drive mechanism. The side sealing assembly is located on the side of the second conveyor belt. The side sealing assembly includes a side sealing frame, a guide roller, a traction roller and a hot cutting knife. The heat shrink film is pulled to the hot cutting knife by the traction roller for sealing and cutting.

[0004] However, the aforementioned sealing and cutting machine still has the following drawbacks:

[0005] First, different products require different sealing films, and the materials of these films vary. The aforementioned flavoring device cannot adjust the height of the sealing and cutting device relative to the packaging frame, thus failing to adapt to different sealing and cutting needs.

[0006] Secondly, the needle wheel usually has multiple needle holes on its circumference, and needles are inserted into the needle holes. Since the needles are cylindrical, larger needles cannot be inserted into the needle holes when inserting needles. The needle wheel has poor adaptability and different needles need to be placed repeatedly to ensure its function, which is inconvenient.

[0007] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content
