Description

Technical Field

[0001] The utility model relates to the technical field of cling film production, in particular to an aluminum foil cling film production and rolling device. Background Art

[0002] Aluminum foil film is a commonly used cling film in households. Wrapping food in aluminum foil film can prevent the entry of air and moisture, thereby extending the shelf life of food. Aluminum foil cling film can also prevent moisture and oxidation, keeping food fresh. For example, when storing nuts, chocolates, candies and other foods, using aluminum foil film can prevent food from getting damp, softening and deteriorating. Aluminum foil cling film requires a winding device for winding and storage during production.

[0003] Aluminum foil cling film may become wrinkled or uneven during the production process. In order to solve this problem, a tensioning mechanism is usually installed on the winding device to straighten the aluminum foil cling film. However, due to the special material of aluminum foil, it is easy to be damaged due to excessive tension, and the general tensioning mechanism is not conducive to adjusting the tension, which is inconvenient when rolling up the aluminum foil cling film.
