Description

Technical Field

[0001] The invention belongs to the technical field of cigarettes, and in particular relates to a sheet material and application thereof, as well as equipment for preparing the sheet material. 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.

[0004] The present invention is proposed for this purpose. Summary of the invention

[0015] The third aspect of the present invention discloses use of the sheet material in tobacco material.

[0016] Preferably, the sheet material is used in the cooling section, the flavoring section or / and the supporting section of the tobacco material of the heating non-combustion cigarette.

[0017] Effects of the present invention:

[0018] The sheet material of the present invention is provided with a convex frame 101, and a through hole 102 is formed in the convex frame 101. The sheet material of the present invention is gathered into a desired shape such as a cylindrical shape, a rod shape, etc., and can be used for heat-not-burn cigarettes, including but not limited to a cooling section, a flavoring section, a support section, etc. When used as a support section, in addition to the through hole 102 for ventilation, the convex frame 101 separates the surface of the sheet material, increasing the air permeability while ensuring the support. When used as a cooling section (rod), the base material of the sheet material can be a material such as polylactic acid, and the convex frame 101 with the through hole 102 separates the adjacent surfaces of the sheet material. In addition to the through hole 102 for ventilation, the convex frame 101 can increase the air permeability to reduce smoke retention, and at the same time use the physical properties of the material itself to reduce temperature (such as polylactic acid). When used as a scenting segment, flavors and fragrances can be directly applied to the sheet material through a carrier. Due to the isolation of the adjacent sheet materials by the convex frame 101, it has a larger fragrance-carrying space, that is, the setting of the convex frame 101 can increase the fragrance-carrying capacity of the sheet material. At the same time, the convex frame 101 provides a certain support force for the flavors and fragrances, so that the fragrance-carrying segment has good stability after scenting; compared with conventional technology, the sheet material of the present invention is used as a scenting segment, and its fragrance-carrying capacity is increased by 2 to 3 times, and the use of substrates is reduced to reduce costs. The height requirement range of the convex frame 101 of the present invention is 0-5mm; the larger the height of the convex frame 101, the higher the ventilation rate, but the worse the support, and the fragrance carrying rate will also decrease; therefore, the higher the height of the convex frame 101, the better.

[0019] In the sheet material preparation device of the present invention, the groove 201 arranged on the surface of the upper roller 2 corresponds to the convex frame 101 of the sheet material; the boss 301 arranged on the surface of the lower roller 3 corresponds to the through hole 102 of the sheet material. The device of the present invention is simple, and the surface structures of the upper roller 2 and the lower roller 3 can be changed and designed according to the requirements of the sheet material.

[0031] A sheet material, wherein the sheet material 1 has a convex frame 101, and a through hole 102 is formed in the convex frame 101.

[0032] Wherein, the height of the convex frame (101) is 0-5mm.

[0033] The convex frames 101 are evenly arranged in parallel on the sheet material 1 , and each row of convex frames 101 is staggered with the adjacent parallel rows of convex frames 101 .

[0034] Preferably, the convex frame 101 is circular, elliptical or polygonal; the through hole 102 is the same or different in shape from the convex frame 101; more preferably, the convex frame 101 is rectangular, such as Figure 1 and Figure 2 The frame height, shape, quantity and arrangement of the convex frame 101 can be designed and replaced according to actual needs.

[0035] The base material of the sheet material 1 is polylactic acid, because polylactic acid can be used as a cooling material.

[0036] The equipment for preparing the sheet material of the present invention, such as Figure 3-Figure 5 As shown, it comprises: an upper roller 2 and a lower roller 3, wherein the surface of the upper roller 2 is provided with a plurality of grooves 201, and the surface of the lower roller 3 is provided with a boss 301.

[0037] The groove 201 corresponds to the convex frame 101 of the sheet material 1 ; and the boss 301 corresponds to the through hole 102 of the sheet material 1 .

[0038] like Figure 3 As shown, the device also includes: a first retaining frame 4, a second retaining frame 12, a base 6, a first gear 5, a second gear 7, a third gear 8, a fourth gear 9, a plurality of deep groove ball bearings 10, two fixing frames 11 and a reduction motor 13;

[0039] The upper roller 2 is installed between the upper part of the first retaining frame 4 and the second retaining frame 12 through two fixing frames 11 and deep groove ball bearings 10; the lower roller 3 is installed between the lower part of the first retaining frame 4 and the second retaining frame 12 through two fixing frames 11 and deep groove ball bearings 10; the fourth gear 9 is fixedly connected to the axle of the upper roller 2; the first gear 5 is fixedly connected to the axle of the lower roller 3; the fourth gear 9 and the first gear 5 are gear-connected through the third gear 8 and the second gear 7; the shaft of the reduction motor 13 is fixedly connected to the axle of the second gear 7; the first gear 5, the second gear 7, the third gear 8 and the fourth gear 9 are respectively installed on the first retaining frame 4 through deep groove ball bearings; the first retaining frame 4 and the second retaining frame 12 are respectively fixedly installed on the machine base 6, and the reduction motor 13 is also fixedly installed on the machine base 6.

[0040] The sheet material of the present invention is used in tobacco materials. The embodiments are the use of the sheet material of the present invention in the cooling section (Example 2), the flavoring section (Example 3) or / and the supporting section of the tobacco material of the heat-not-burn cigarette.

[0041] Example 1: Use Figure 3-Figure 5 In the step of preparing the sheet material by the device, the convex frame 101 is rectangular, the height of the convex frame 101 is 2 mm, and the through hole 102 is also rectangular.

[0042] The output shaft of the reduction motor 3 rotates clockwise, causing the second gear 7 to rotate clockwise, driving the first gear 5 to drive, and driving the lower roller 3 to rotate counterclockwise. At the same time, the second gear 7, the third gear 8 and the fourth gear 9) drive the upper roller 2 to rotate clockwise. The upper roller 2 and the lower roller 3 rotate synchronously in opposite directions, and the distance between the upper roller 2 and the lower roller 3 can produce a through hole 102. During rotation, the rectangular groove 201 on the surface of the upper roller 2 and the rectangular boss 301 on the surface of the lower roller 3 engage one by one to produce a convex frame 101 and a through hole 102. The base material of the sheet material (polylactic acid in this embodiment) enters the gap between the upper roller 2 and the lower roller 3 for compression molding, forming a sheet material with a 2mm rectangular convex frame 101 and a rectangular through hole 102, such as Figure 1 and Figure 2 shown.

[0043] Example 2: The sheet material obtained in Example 1 is used in the cooling section of heat-not-burn cigarettes.

[0044] When the sheet material obtained in Example 1 is used as a cooling section of a heat-not-burn cigarette, the sheet substrate is polylactic acid, which is gathered and formed into a cylindrical rod, and the 2 mm rectangular convex frame 101 of the sheet material separates the surfaces of adjacent sheet materials, and the through holes 102 on the surface of the convex frame 101 form a porous high air permeability cooling section. When the heated aerosol flows from the cigarette core section into the cooling section, the physical properties of the polylactic acid material itself reduce the aerosol temperature, and at the same time, due to the porous and high air permeability structural characteristics, the interception of the heated cigarette smoke is greatly reduced.

[0045] Example 3: The sheet material obtained in Example 1 is used for the flavoring section of heat-not-burn cigarettes.

[0046] When the sheet material obtained in Example 1 is used as a flavoring segment of a heat-not-burn cigarette, the flavor gel mixture is evenly applied on the upper surface of the sheet material with a rectangular convex frame 101, and the sheet material is gathered to form a cylinder. At this time, the flavor gel mixture is evenly distributed between the surfaces of the sheet material. At this time, the 2mm rectangular convex frame 101 provides a strong bearing effect on the flavor gel mixture, and then it is wrapped by a forming paper with an anti-permeation function. After the flavoring segment is processed, it is installed between the support segment and the filter segment of the heat-not-burn cigarette. When inhaling, the cigarette core segment is heated by the heating device to release aerosol. When passing through the flavoring segment, the flavor gel mixture applied to the sheet material releases fragrance. Because the sheet material of the present invention has a higher fragrance carrying capacity, the gas entering the oral cavity from the filter segment is full and full of fragrance.

[0047] The base material of the sheet material of this embodiment is polylactic acid. Since polylactic acid can also be used as a cooling material, the aroma-enhancing segment of this embodiment has both aroma-enhancing and cooling effects. In this way, only one cylindrical segment of the sheet material of the present invention is needed to have both cooling and aroma-enhancing effects. The aroma-enhancing segment of this embodiment has a good cooling effect and increases the stable release of aroma, reduces the processing steps of heated cigarettes, and reduces costs.

[0048] The above embodiments are not limitations of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essential scope of the present invention also fall within the protection scope of the present invention.
