Description

Technical Field

[0001] The utility model relates to the technical field of film wrapping machines, in particular to a track-type automatic film wrapping machine. Background Art

[0002] Film wrapping machines are mainly used for material packaging. During the packaging process, the material needs to be wrapped with film to protect the material box. The existing film wrapping machines are mainly special packaging machines for realizing mechanized film wrapping. They are indispensable packaging machines in the packaging process of modern enterprises, especially export-oriented enterprises.

[0003] Existing wrapping machines mainly adopt a fixed wrapping method, which requires manual placement or conveyor belts to transport material boxes. When placing material boxes by manual placement, it is necessary to ensure that the material boxes are aligned with the wrapping station. Manual lifting and placing of material boxes is likely to result in high labor costs, and the work efficiency of manual placement of material boxes is not high. If a material conveyor belt is used to transport materials to the wrapping station, the material is likely to be shifted during the transportation process, affecting the accuracy of the subsequent wrapping position.
