[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Please refer to Figure 1-2 , Figure 1 A schematic structural diagram of an embodiment of a high-toughness cigarette structure provided by the utility model; Figure 2 This is a partial structural schematic diagram of an embodiment of the high-toughness cigarette structure provided by the utility model.
[0024] In a specific embodiment, the high-toughness cigarette structure includes a cigarette body, which includes white paper 11, aluminum foil 13, tobacco 20 arranged from the outside to the inside, and an elastic coating 12 arranged on the side of the white paper 11 facing the aluminum foil 13. The white paper 11, the elastic coating 12, and the aluminum foil 13 are connected to form a wrapping paper 10. The elastic coating 12 is used to bond the white paper 11 and the aluminum foil 13 and to improve the elasticity and toughness of the wrapping paper 10. The aluminum foil 13 is provided with an undulating structure in the length direction of the cigarette body.
[0025] By providing an undulating structure on the aluminum foil 13 in the length direction of the cigarette body, a stronger supporting force is provided for the cigarette body. By providing an elastic coating 12 between the white paper 11 and the aluminum foil 13, the elastic coating 12 is utilized to improve the toughness and elasticity of the packaging paper 10 and prevent the cigarette from deformation.
[0026] In the present application, an undulating structure is provided to transform the original flat aluminum foil 13 into a three-dimensional aluminum foil 13 with an undulating structure. Compared with the original flat structure, it has stronger toughness and can provide stronger supporting force. The staff can select different amplitudes according to the supporting force requirements.
[0027] The role of the undulating structure in the present application is similar to the structure of the corrugated paper in the prior art. By setting a wavy structure in the middle of the corrugated paper, the overall structural strength is greatly improved. In the present application, since the tobacco 20 is wrapped with aluminum foil 13 and white paper 11, its structure is the same as the structural principle of the corrugated paper, which can greatly improve its supporting force and reduce the possibility of the cigarette being bent.
[0028] The shape and size of the undulating structure are not limited in the present application. The undulating structure is a sinusoidal wave undulating structure, a sawtooth wave undulating structure or a rectangular wave undulating structure, or other structures, or other waveform structures, or waveform-like structures, or a structure formed by combining waveforms and waveform-like structures.
[0029] In order to achieve standardized production, the complexity of the undulating structure, the complexity of the equipment and the process flow should be reduced while ensuring its structural strength.
[0030] In one embodiment, the waveform wavelengths and amplitudes of the sinusoidal wave undulating structure, the sawtooth wave undulating structure, and the rectangular wave undulating structure are equal everywhere.
[0031] That is, by using the same wavelength and amplitude undulating structure in the same type of cigarettes, it is possible to achieve large-scale and standardized production, greatly reducing production costs. At the same time, the undulating structure is almost unobservable in the appearance of the cigarettes, thereby improving their aesthetics.
[0032] This application does not limit the waveform wavelength and amplitude of the undulating structure.
[0033] In the present application, an undulating structure is arranged along the length of the cigarette body, and the structure perpendicular to the axial direction is not limited. In one embodiment, the sinusoidal wave undulating structure, the sawtooth wave undulating structure, and the rectangular wave undulating structure are undulating structures arranged in a circumferential spiral or are positive undulating structures in the length direction of the cigarette body.
[0034] By arranging an undulating structure in a circumferential spiral, the cigarette can not only resist bending force, but also resist torsional force, thereby improving the ability to resist external forces.
[0035] Since the circumferential spiral undulating structure is a spiral structure in the length direction of the cigarette body, it is relatively complex. Therefore, in order to reduce the difficulty of processing, a positive undulating structure in the length direction of the cigarette body can also be provided, that is, the undulating structure will not rotate in the circumferential direction, thereby reducing the difficulty of processing.
[0036] The present application includes but is not limited to the above-mentioned structures, and other combined structures may also be adopted.
[0037] In the present application, printing such as gravure printing equipment or other embossing equipment can be used for periodic printing, or other methods can be used to obtain the undulating structure.
[0038] In order to further improve the quality of cigarettes, reduce the residual air in the tobacco 20 of cigarettes, improve the distribution uniformity of the tobacco 20, improve the user experience, and avoid the uneven flavors carried by the tobacco 20, in one embodiment, the high-toughness cigarette structure also includes air holes 30 set through the white paper 11, the elastic coating 12, and the aluminum foil 13, which are used to connect the air between the tobacco 20 with the air outside the white paper 11.
[0039] By providing the ventilation holes 30, the air between the tobacco shreds 20 is connected to the air outside the white paper 11, so that even if air appears between the tobacco shreds 20 during the wrapping of the tobacco shreds 20, it can be discharged through the ventilation holes 30, thereby avoiding the occurrence of local air collapse structure and local cavitation, reducing the loss rate of cigarettes and improving their finished product rate.
[0040] The present application does not limit the size, shape and arrangement of the air holes 30 .
[0041] In one embodiment, the air holes 30 are arranged at the crests or troughs of the sine wave undulating structure, the sawtooth wave undulating structure, or the rectangular wave undulating structure.
[0042] By setting the air holes 30 at the crests or troughs of the undulating structure, on the one hand, the air holes 30 can be concentrated in a special position to facilitate alignment and improve the accuracy of the product. On the other hand, if the thickness is sufficient, the actual penetration thickness can be reduced by punching at the position with the smallest thickness, thereby reducing the difficulty of processing. If the strength is low, holes can be punched in the area with the largest thickness to reduce damage to the components.
[0043] The present application includes but is not limited to the above-mentioned location of the vent hole 30 .
[0044] Preferably, the air vent 30 is disposed at the center of the wave crest or the wave trough.
[0045] By setting the air hole 30 at the center of the crest or the trough, automatic alignment can be achieved, and the difficulty of punching is reduced. At the same time, larger air holes 30 can be set to reduce the difficulty of setting them. Even for larger air holes 30, due to their symmetrical setting, the actual penetration thickness is reduced, thereby reducing the processing difficulty.
[0046] The shape, number, location and size of the air holes 30 are not limited in the present application. The shape of the air holes 30 is circular, rectangular or elliptical, or other shapes, such as regular polygons, etc., and the processing of the air holes 30 can be achieved by laser drilling, mechanical processing, or other methods.
[0047] Generally, the diameter of the air holes 30 is 80-150 μm, and the staff can select the air holes 30 of appropriate shape and size as needed.
[0048] In one embodiment, the white paper 11 and the aluminum foil 13 are bonded by the elastic coating 12, so that the wrapping paper 10 has high elasticity and will not be irreversibly damaged during use. The present application does not limit the material, thickness, etc. Generally, the thickness of the elastic coating 12 is 100-300 μm.
[0049] In one embodiment, the process flow of the high-toughness cigarette structure is as follows:
[0050] 1. Press spiral wavy folds on the aluminum foil 13, and apply an elastic coating 12 on the inner side of the lining paper;
[0051] 2. Pressing the wrinkled aluminum foil 13 to the inner side of the elastic coating 12 to form an aluminum foil roll;
[0052] 3. Using laser to evenly open air holes 30 on the wrapping paper 10 along the trough section of the aluminum foil 13, and then feeding the opened wrapping paper 10 into a cigarette rolling machine to roll in the shredded tobacco 20 to form a cigarette;
[0053] The spiral wavy folds extend along the length of the cigarette; the elastic coating 12 includes polyvinyl acetal solution, curing agent, filler, film-forming aid, etc., and the thickness of the elastic coating 12 is 100-300 μm; 4. The diameter of the air pores 30 is 80-150 μm.
[0054] In the structure of the specific process: spiral wavy folds are pressed on the aluminum foil 13, an elastic coating 12 is coated on the inner side of the white paper 11, and then the wrinkled aluminum foil 13 is crimped to the inner side of the elastic coating 12 to form a cigarette wrapping paper 10, and then a laser is used to evenly open air holes 30 on the wrapping paper 10 along the trough section of the wrinkles of the aluminum foil 13, and finally the wrapping paper 10 with holes opened is sent to a rolling machine to roll in tobacco shreds 20 to form a cigarette.
[0055] The wrinkled aluminum foil 13 improves the overall supporting force of the cigarette wrapping paper 10, and the elastic coating 12 serves to bond the white paper 11 and the aluminum foil 13 while improving the elasticity and toughness of the wrapping paper 10, greatly enhancing the strength of the cigarette wrapping and reducing the risk of cigarette deformation and appearance defects. The ventilation holes 30 increase the air circulation inside the cigarette and improve the taste of the cigarette.
[0056] In summary, the high-toughness cigarette structure provided by the embodiment of the utility model provides a stronger supporting force for the cigarette body by arranging an undulating structure on the aluminum foil in the length direction of the cigarette body, and by arranging an elastic coating between the white paper and the aluminum foil, the high elasticity of the coating is utilized to improve the toughness and elasticity of the packaging paper, thereby preventing the cigarette from being deformed.

This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
