Description

Technical Field

[0001] The utility model relates to the field of aluminum foil production, in particular to an aluminum foil coating and winding device. Background Art

[0002] Aluminum foil refers to paper made of aluminum foil backing paper and aluminum foil pasted together. It is soft and easy to deform, just like paper, and it does not rebound after deformation. It can be qualitative, ensure light blocking, will not fall off, is not light-transmissive, has no pollution, and is cheap. It is used for moisture-proof and decorative packaging of high-end cigarettes, candies and other foods. After coating, aluminum foil needs to be cooled by cooling rollers and needs to be rolled up after cooling.

[0003] After searching, the Chinese patent announcement number CN218642088U is found, which discloses an aluminum foil coating and winding machine. This patent uses a leveling plate to cooperate with a limit rod and a spring to level the aluminum foil rolled up on the winding roller, ensuring that the rolled-up aluminum foil will not have wrinkles. At the same time, a storage tank is used to cool the rolled-up aluminum foil to prevent the uncooled aluminum foil from sticking to each other and causing trouble for subsequent use.

[0004] One end of the screed plate in the above patent is connected to a spring to facilitate the movement of the screed plate as the diameter of the winding roller changes. However, as the amount of aluminum foil wrapped around the winding roller increases, the spring is compressed more, and the pressure of the screed plate on the aluminum foil becomes greater, which may cause damage to the aluminum foil and increase the resistance to winding.
