Description

Technical Field

[0001] The utility model relates to a cigarette rod with natural air permeability, belonging to the technical field of cigarettes. Background Art

[0002] Mainstream cigarettes adopt the filter tip punching ventilation technology to dilute the smoke so as to reduce the content of total particulate matter in the mainstream smoke of cigarettes.

[0003] At present, there are mainly two ways to adopt the filter tip punching ventilation technology for mainstream cigarettes: one is to use pre-punched tipping paper, and the other is to use online punching, so as to utilize the negative pressure formed inside the cigarette rod during cigarette suction, and enable air to enter the mainstream smoke through the small holes in the filter tip punching while the mainstream smoke moves towards the oral cavity, achieving the effect of diluting the mainstream smoke and reducing the content of total particulate matter therein.

[0004] The filter tip punching ventilation technology is affected by factors such as the punching air permeability of the tipping paper, the air permeability of the filter rod forming paper, the adhesive coating and bonding, as well as the interaction among the three, and there are problems such as unnatural, uneven and unstable ventilation.

[0005] When a smoker smokes a cigarette, air enters the mainstream smoke through the small holes in the filter tip tipping paper. When the suction stops, a little mainstream smoke continues to move towards the suction end and diffuse into the air due to its high temperature and high pressure characteristics, and basically cannot diffuse into the air through the small holes in the filter tip tipping paper. As a result, the total particulate matter in the mainstream smoke is intercepted and accumulated in the filter tip, resulting in the total particulate matter in the mainstream smoke continuing to enter the oral cavity when taking the next puff, making the tar content in the smoke higher when the smoker smokes, and the harm of the smoke to human health and the environment is greater.

[0006] In addition, during the combustion process of existing cigarette rods, sulfur compounds in the smoke are a kind of gases with unpleasant odors and are the main reasons for the bad breath in the oral cavity of cigarette consumers. Among the sulfur compounds in the smoke, the vast majority is hydrogen sulfide gas, and its content is more than twice the total content of other sulfur compounds. Therefore, it is one of the main negative impact substances that need to be considered for removal. At present, technicians in the tobacco field pay little attention to sulfur compounds in cigarette smoke, and even fewer people pay attention to the removal methods of sulfur compounds.

[0007] In order to solve the above problems, the present utility model is proposed. Content of the Utility Model

[0023] (c)The filter rod, cigarette rod formed by shaping the formed paper obtained in step (b), and the tipping paper obtained in step (a) are used for rolling and joining by a cigarette making and tipping unit with an intermittent tipping paper splicing device to obtain the cigarette.

[0024] Preferably, the tipping paper cutting and separating device cuts off the tipping paper in the ventilation zone, and the cutting and separating width of the tipping paper is 3 mm to 10 mm.

[0025] Preferably, the tipping paper cutting and separating device cuts off the tipping paper in the ventilation zone of the tipping paper and the tipping paper in the suction end zone of the filter rod, and only the tipping paper connecting the filter rod and the cigarette rod area is retained.

This method first cuts and separates the cigarette tipping paper, and then rolls and joins it with a common filter rod or a composite filter rod with low air permeability, so that a circular cigarette filter tip ventilation zone is formed on the cigarette filter tip. When smoking, air naturally and evenly enters the mainstream smoke through the ventilation zone to dilute the mainstream smoke. When smoking stops, the mainstream smoke diffuses out into the air through the ventilation zone due to the characteristics of high temperature and high pressure, reducing the accumulation of total particulate matter in the filter tip, achieving double tar reduction, significantly enhancing the smoking experience of smokers and reducing the harm to the environment at the same time.

[0031] (5) Another important innovation of the utility model is that a cigarette filter particle capable of reducing smoke odor is prepared by combining konjac powder, iron hydroxide powder, glycerol and carboxymethyl cellulose.

[0041] Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. In the embodiments, the composite filter rod with a length of 50 mm and a circumference of 17.01 mm is formed by using an imported KDF4 filter rod forming machine, and the cigarette rod is rolled by using a domestic ZJ118 cigarette making unit with a tipping paper cutting and separating device. Embodiment 1

[0042] As shown in Figure 1(a), a cigarette rod with natural air permeability has a cylindrical shape and includes the following components:

[0043] A tobacco rod (3), which is located at the upper part of the cigarette rod. The tobacco rod (3) is wrapped with cigarette paper on the outside and contains cigarette tobacco inside.

[0044] A filter rod (2), which is located at the lower part of the cigarette rod. The filter rod (2) is wrapped with a forming paper (8) on the outer layer.

[0045] There are 2 tipping papers (1). The tipping papers (1) wrap the filter rod (2) and the area connecting the filter rod (2) and the tobacco rod (3). The tipping papers (1) are distributed at intervals, and the distance between the two tipping papers is 5 mm. An annular air permeable belt (6) is formed between adjacent tipping papers, and the forming paper (8) is exposed through the air permeable belt (6).

[0046] The filter rod (2) is a two-stage composite filter rod.

[0051] Compared with the cigarette stick without adding such filter tip particles (with other conditions being the same), the hydrogen sulfide content released in the flue gas is reduced by 92%. According to the sensory evaluation results of the national standard "Cigarettes - Part 4: Sensory Technical Requirements" (GB5606.4 - 2005), there is no significant impact on the aroma, and there is basically no peculiar smell in the mouth after smoking.

[0052] A preparation method of a cigarette stick with natural air permeability includes the following steps:

[0056] As shown in Figure 1(b), a cigarette stick with natural air permeability, in the shape of a cylinder, includes the following components:

[0057] A tobacco rod (3), which is located at the upper part of the cigarette stick. The tobacco rod (3) is wrapped with cigarette paper on the outside and contains cigarette tobacco inside;

[0058] A filter rod (2), which is located at the lower part of the cigarette stick. The outer layer of the filter rod (2) is wrapped with a forming paper (8);

[0059] A tipping paper (1), with the number of 1 strip. The tipping paper (1) is only distributed in the area connecting the filter rod (2) and the tobacco rod (3), and the suction end of the filter rod (2) does not include the tipping paper (1).

[0060] The filter rod (2) is a two - section composite filter rod. One section close to the suction end is the first base rod (4), which is composed of porous cellulose acetate microspheres, and a flavor wire (5) is arranged at the central axis position inside. The other section far from the suction end is the second base rod (7), which contains filter tip particles inside. The filter tip particles are composed of konjac powder, iron hydroxide powder, glycerol and a binder, and the binder is carboxymethyl cellulose.

[0061] The preparation method of the filter tip particles comprises the following steps:

[0062] A. Mix konjac powder with 90 - 120 mesh and ferric hydroxide powder in a mass ratio of 5:2 to obtain a mixed powder;

[0063] B. Add glycerol and carboxymethyl cellulose. The added mass of glycerol is 28% of the mass of the mixed powder, and the added mass of carboxymethyl cellulose is 3% of the mass of the mixed powder. Then, use the wet granulation process for granulation, and screen out particles with 30 mesh;

[0064] C. Conduct low - temperature drying on the screened particles at a temperature of 70 - 80 °C to obtain the filter tip particles.

[0065] Compared with a cigarette stick without adding such filter tip particles (with other conditions being the same), the content of hydrogen sulfide released in the flue gas is reduced by 92%. According to the sensory evaluation results of the national standard "Cigarettes - Part 4: Sensory Technical Requirements" (GB5606.4 - 2005), there is no significant impact on the aroma, and there is basically no peculiar smell in the mouth after smoking.

[0066] A preparation method of a cigarette stick with natural air permeability comprises the following steps:

[0067] (a) Use the tipping paper cutting and separating device of the cigarette making machine set to complete the cutting and separation of the tipping paper (1). The tipping paper cutting and separating device cuts off the tipping paper in the area of the ventilation band (6) and the tipping paper in the suction end area of the filter rod (2), and only retains the tipping paper in the area connecting the filter rod (2) and the tobacco rod (3).

[0068] (b) Select a low - air - permeability colored forming paper with an air permeability of 80 CU and a width of 19.0 mm to form a two - section composite filter rod with a length of 50 mm and a circumference of 17.01 mm on the machine.

[0069] (c) Use the cigarette making machine set with an intermittent tipping paper splicing device to roll and splice the two - section composite filter rod obtained in step (b), the tipping paper obtained in step (a), and the tobacco rod (3). The intermittent splicing device is equipped with an adhesive roller with a non - adhesive area and an adhesive area. The non - adhesive area is the area of the ventilation band (6) and the suction end area of the filter rod (2), and the adhesive area is the area of the tipping paper (1), thus obtaining the cigarette stick.

[0070] Compare the obtained cigarette sticks with online - punched tipping paper and cigarette sticks with a high air permeability of 6000 CU. The physical indexes and flue gas indexes of the cigarette sticks are as follows in the table:

[0071]

[0072] By comparison, it is not difficult to see that for the cigarette rod of the present utility model, by using a forming paper with a low air permeability of 80 CU, a circular air permeability band with a width of 5 mm is formed between two adjacent tipping papers. The forming paper is exposed outside through the air permeability band. When smoking, air naturally and evenly enters the mainstream smoke through the air permeability band to dilute the mainstream smoke. When smoking stops, due to the characteristics of high temperature and high pressure, the mainstream smoke diffuses out into the air through the air permeability band, reducing the accumulation of total particulate matter in the filter tip, achieving the technical effect of double tar reduction, and the tar content is only 7.9 mg / cigarette. Compared with the on-line perforated tipping paper and the cigarette rod with a high air permeability of 6000 CU, it not only eliminates the need for on-line perforation of the cigarette filter tip, avoiding the quality risks brought by the on-line perforation process during cigarette production, but also uses a forming paper with a lower air permeability of 80 CU compared to 6000 CU, and also achieves a better tar reduction effect with a tar content of only 7.9 mg / cigarette.

[0073] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present utility model should be covered by the protection scope of the present utility model.
