Description

Technical Field

[0001] The utility model relates to the technical field of lining paper processing, in particular to an aluminum foil flattening device for lining paper processing. Background Art

[0002] Most liner papers used in the tobacco industry are unscented. Liner paper primarily serves to protect cigarettes from moisture, preserve aroma, and wrap cigarettes. Domestic cigarette liner paper primarily consists of composite materials, including aluminum foil, composite adhesives, and backing paper. With the increasing adoption of non-combustible flavoring and the functionalization and differentiation of packaging materials within the industry, the use of liner paper to impart a fresh and elegant "open-pack aroma" to cigarettes is becoming a future trend.

[0003] A search revealed an aluminum foil flattening device disclosed in Chinese Patent Application No. 202221515416.3, which includes a frame equipped with a tension roller assembly. A unwinding air-expansion shaft and a rewinding air-expansion shaft are rotatably mounted on either side of the tension roller assembly. The unwinding air-expansion shaft has an unwinding support at one end, a first rotating shaft rotatably mounted on the unwinding support, a brake disc sleeved on the shaft, and a pneumatic disc brake on one side. The first rotating shaft is connected to the unwinding air-expansion shaft via a coupling. The rewinding air-expansion shaft has a rewinding support at one end, a second rotating shaft rotatably mounted on the rewinding support, one end of the shaft connected to the rewinding air-expansion shaft via a coupling, and the other end of the shaft sleeved with a fixed disc, a pulley, and a handwheel.
