Description

Technical Field

[0001] The invention belongs to the technical field of cigarettes, and in particular relates to a film coating and gathering device, a use method and purpose thereof. Background Art

[0002] As people in various countries pay more and more attention to health, heated cigarettes have gradually entered the public eye due to their low harm. Heated cigarettes are a product that produces aerosols by cooperating with heated tobacco devices. The heating temperature generally reaches 200℃-400℃, and since there is no combustion and no high-temperature cracking process, the release of harmful substances is greatly reduced. In order to give consumers a good consumption experience, the smoke inlet temperature needs to be low and the aroma is full and full. This requires the full volatilization of the heated cigarette core, and the cigarette has a certain aroma-carrying capacity and a good cooling effect.

[0003] At present, the cooling methods generally used for heated cigarette products include: using wrinkled and gathered films, designing spiral structures to increase the length of the airway, and using hollow tubes to use the Venturi effect to cool down. The existing cooling methods mainly have problems such as complex processing technology, high production cost, large aroma interception, and poor cooling effect. In terms of flavoring heated cigarettes, the current mainstream method is mainly to add burst beads to the filter rods of heated cigarettes, or directly mix flavors in the core material. However, the production cost of burst beads is high, and the aroma release is uneven, and mixing flavors in the core material is likely to cause poor aroma release stability and affect the aroma release of the core material. Patent CN109846084A reports the use of polylactic acid filament composite filter rods for cooling, the gaps between the polylactic acid filaments are filled with fillers, and the circumferential surfaces of the polylactic acid filaments and fillers are evenly coated with plasticizers or tow adhesives for filter rod molding. However, the fillers between the polylactic acid filaments may evaporate with the smoke during the smoking process, bringing a bad smoking experience. Patent CN210043187U reports that the purpose of increasing fragrance and reducing temperature is achieved by gathering polylactic acid films and placing non-woven fabrics in the middle. However, the fragrance carrying capacity of non-woven fabrics is limited, and the processing technology is complicated and the processing cost is high.
