Description

Gradient coated cigarette paper with positioning marks and coating method

technical field

The invention belongs to the technical field of cigarette paper, and in particular relates to a gradually changing coated cigarette paper with positioning marks and a coating method.

Background technique

Cigarette paper belongs to thin sheet paper, generally between 26-34g/m ² , cigarette paper, as the packaging paper for cigarette products, occupies an important position in the tobacco industry. Cigarette paper generally accounts for 5% of the total weight of cigarettes. Because it directly participates in combustion, cigarette paper can affect the flammability, flavor, and tar production of cigarettes by controlling the flammability of cigarettes and the dilution of smoke. And other harmful components of smoke, especially the production of carbon monoxide.

During the smoking process of the cigarette, the shredded tobacco in the cigarette branch section and the cellulose acetate tow in the filter rod all play a certain role in filtering the smoke. With the burning of cigarettes, when the cigarettes become shorter and shorter, the unburned shredded tobacco and filter rods in the cigarette section will become weaker and weaker in filtering cigarette smoke. Strictly speaking, every puff of cigarette smoke is different. In order to eliminate the mouth-to-mouth inconsistency caused by the difference in the "filter structure" caused by the burning of cigarettes, it needs to be eliminated through the cigarette paper that participates in the combustion.

At present, the length of conventional cigarettes is 84mm (60mm+24mm, 59mm+25mm), 92mm (62mm+30mm), 100mm (70mm+30mm), the length of the cigarette end is 60mm, 59mm, 62mm or 70mm, and the length of the filter tip is 24mm, 25mm, 30mm, 30mm, the length of the end of the cigarette or the length of the filter end is the length of a cut tobacco cigarette section or filter end of a certain width. In order to reduce the short-cut U-turn at the end of the cut tobacco, there is generally a tight end area, the length of which is generally about 10mm. In this area, the shredded tobacco is tight, and the smoke of each cigarette does not change much; in addition, during the smoking process of the cigarette, Generally, it will not burn to the tipping paper area, which includes the overlapping portion of the cut tobacco paper and the filter paper.

Contents of the invention

In order to solve the above problems, the present invention improves the functions of the cigarette paper in a more refined manner, that is, the cigarette paper is firstly positioned and marked, and then the functional additives to be coated are carried out on the cigarette paper in a certain area on the cigarette paper. Gradient coating, the functional additives on the coating become thicker or thinner gradually. With the cigarettes made of this cigarette paper, as the cigarettes are burned, every puff of the cigarettes is close to or the same, so as to weaken or eliminate the problem of inconsistency between the mouth and the mouth of the smoke. The positioning mark is beneficial to the subsequent coating and cutting of the cigarette paper, so as to ensure that the coating area of each cigarette is close to or the same. Since the cigarette paper in the overlapping area of the tipping paper and the cigarette paper does not participate in the combustion of the cigarette, in the detection of various indicators of the mainstream smoke of the cigarette, generally the length of the tipping paper + 3mm is drawn on the cigarette paper and placed on the When the cigarette paper burns to this line, the burning process of the cigarette is terminated. Therefore, the cigarette paper in this area has no effect on the mouth-to-mouth consistency of the smoke, and there is no need to coat the overlapping area between the tipping paper and the cigarette paper. When performing identification positioning, it can be identified in advance.

The first aspect of the present invention relates to a progressively coated cigarette paper with positioning marks. There are positioning marks on the cigarette paper, and a coating with additives gradually increasing or decreasing is coated in a certain area.

Preferably, the gradient coated cigarette paper with positioning marks is cigarette paper, wrapping paper or tipping paper. In the actual process of making cigarettes from cigarette paper, only one or several of them can be used for cigarette paper, molding paper or tipping paper.

Preferably, the positioning mark is a positioning hole punched by a laser; the positioning hole punched by the laser is not only conducive to the precise positioning of the cigarette paper coating area, but also will be sensed by the cigarette machine probe during the subsequent cigarette rolling process of the cigarette paper , and cut the cigarette at this position.

The second invention of the present invention relates to the coating method of the gradient coating cigarette paper with positioning marks, comprising the following steps:

(1) Determine the area of the coating area to be coated according to the thickness and length of the cigarette, and give a positioning mark;

(2) Determine the type and proportion of substances that need to be coated according to the calculated gradient coating trend;

(3) According to the area of the coating area determined in step (1) and the type and proportion of substances to be coated determined in step (2), several coating hole belts are set on the cigarette paper coating roller, and the coating holes The belt communicates with the coating substance; the coating is coated with a gradually increasing or gradually decreasing additive in a defined area; the coating can gradually become thicker or gradually thinner, as long as the additive in the set coating gradually increases or decreases. Gradually reduce to meet the requirements.

(4) Gradual coating is carried out to cigarette paper with cigarette paper coating roller;

(5) Slitting the gradient coated cigarette paper in step (4) along the positioning mark.

In a preferred embodiment, the coating hole zone in step (3) is more than 2 rows of wire holes.

In a preferred embodiment, the number of holes in each row of the wire holes is 10-50; the diameter of the wire holes is 0.02-0.15 mm.

Specific gradient-coated cigarette paper and coating method Taking the smoke of Fen-flavor cigarettes as an example, through the analysis of smoke components, β-ionone, 2-acetylpyrrole, norsoladione, and new plant Diene, macrostigmatrienone, pyridine, 3-picoline, 3-ethylpyridine, limonene, furfural, phenylacetaldehyde, 1,3-cyclopenten-2-one, β-damascenone, β -Dihydrodamascone, phenylacetic acid, palmitic acid, p-ethylphenol and solanone are the main characteristic aroma components of the smoke of the light-flavored cigarettes; after manual smoking and fitting of 18 components, these 18 components and The quantitative relationship of the smoke of light-flavored cigarettes is:

f(x)＝2.112x ₁ +10.705x ₂ +25.421x ₃ +0.450x ₄ +6.172x ₅ +41.201x ₆ –1.115x ₇ –2.354x ₈ +12.221x ₉ –3.688x ₁₀ –92.035x ₁₁ +22.115 x ₁₂ +35.785x ₁₃ +4.393x ₁₄ +27.635x ₁₅ –0.082x ₁₆ +60.772x ₁₇ +103.272x ₁₈ +50.063.

After manual smoking, when f(x) is 80≤f(x)≤90, it can be considered that the smoke of the cigarette is of the fragrance type. If it exceeds this range, the flavor of the smoke will deviate from the fragrance type. The more the excess, the greater the deviation. big.

The present invention unexpectedly finds that, without coating anything on the cigarette paper, after manual smoking (taking 8 puffs of cigarettes as an example), the fragrance of the smoke deviates greatly from the fragrance type, and the mouth and mouth are inconsistent; Component analysis (taking 8 cigarettes as an example), β-ionone, 2-acetylpyrrole, norsoladione, neophytadiene, macrostigmatrienone, pyridine, 3-methyl Pyridine, 3-ethylpyridine, limonene, furfural, phenylacetaldehyde, 1,3-cyclopenten-2-one, β-damascenone, β-dihydrodamascenone, phenylacetic acid, palmitic acid, p-ethyl Base phenol and solanone are 18 ingredients substituted into the formula, and f(x) is 71≤f(x)≤97, which has a large deviation from manual evaluation.

When four extracts of A (C2F extract), B (tobacco leaf B2F tobacco extract), C (X2L tobacco extract), D (H2F tobacco extract) are coated on the cigarette paper, and the four plant extracts are respectively The coated substance is coated at 0.5wt% on the cigarette paper, and through manual smoking (taking 8 puffs of cigarettes as an example), the fragrance of the smoke is a light fragrance type, and the mouth-to-mouth consistency is close; Component analysis (taking 8 cigarettes as an example), β-ionone, 2-acetylpyrrole, norsoladione, neophytadiene, macrostigmatrienone, pyridine, 3-methyl Pyridine, 3-ethylpyridine, limonene, furfural, phenylacetaldehyde, 1,3-cyclopenten-2-one, β-damascenone, β-dihydrodamascenone, phenylacetic acid, palmitic acid, p-ethyl Base phenol and solanone are 18 ingredients that are substituted into the formula, and f(x) is 78≤f(x)≤93, which has some deviations from manual evaluation, but the deviation is not large.

When four kinds of extracts A, B, C, and D are coated in a gradual manner on the cigarette paper, and the gradual coating method (take 8 puffs of cigarettes as an example, the coating arm force gradually decreases, and 8 gradient ranges are set) The ratio is:

1:0.52:1.11:1.32 (mass ratio of the four substances), 1.5-1.25wt% (the total amount of the four substances accounts for the mass percentage of the cigarette paper in the total coating area);

1:0.45:1.22:1.43 (mass ratio of the four substances), 1.25-1.05wt% (the total amount of the four substances accounts for the mass percentage of the cigarette paper in the total coating area);

1:0.45:1.21:1.55 (mass ratio of the four substances), 1.05-0.95wt% (the mass percentage of the total amount of the four substances in the total coating area of the cigarette paper);

1:0.42:1.32:1.65 (mass ratio of the four substances), 0.95-0.80wt% (the total amount of the four substances accounts for the mass percentage of the cigarette paper in the total coating area);

1:0.38:1.41:1.75 (mass ratio of the four substances), 0.80-0.65wt% (the mass percentage of the total amount of the four substances in the total coating area of the cigarette paper);

1:0.35:1.50:1.83 (mass ratio of the four substances), 0.65-0.55wt% (the mass percentage of the total amount of the four substances in the total coating area of the cigarette paper);

1:0.35:1.65:1.92 (mass ratio of the four substances), 0.55-0.35wt% (the mass percentage of the total amount of the four substances in the total coating area of the cigarette paper);

After manual smoking (taking 8 puffs of cigarettes as an example), the aroma of the smoke is light, and the mouth-to-mouth consistency is good; through the analysis of smoke components (8 puffs of cigarettes are taken as an example), the mainstream smoke In the air, β-ionone, 2-acetylpyrrole, norsoladione, neophytadiene, macrostigmatrienone, pyridine, 3-picoline, 3-ethylpyridine, limonene, furfural, phenylacetaldehyde , 1,3-cyclopenten-2-one, β-damascenone, β-dihydrodamascenone, phenylacetic acid, palmitic acid, p-ethylphenol and solanone are 18 ingredients into the formula, f(x ) is 81≤f(x)≤89, which is basically the same as manual suction evaluation.

Then, according to the area of the above-mentioned determined coating area and the type and proportion of the substance to be coated, a number of coating hole belts are set on the cigarette paper coating roller, and the coating hole belts communicate with the coating material; The inner layer is coated with a coating with additives gradually increasing or decreasing; the diameter of the coating hole on the coating roller is in the range of 0.02-0.15mm, and the number of holes in the hole is gradually distributed in the range of 10-50. After the types and proportions of the substances to be coated are determined, the diameter and number of holes on the coating roller can be adjusted appropriately, as well as the speed of the coating roller. In this way, the desired graded coated cigarette paper can be obtained.

Turn on the coating machine and use the cigarette paper coating roller to gradually coat the cigarette paper; then cut the coated gradually coated cigarette paper along the positioning mark.

The beneficial effects of the present invention are:

1. A gradient coated cigarette paper with positioning marks of the present invention is coated with a coating that gradually increases or decreases according to the set additives on the determined area of the cigarette paper; the coating can gradually become thicker or gradually Thinning, as long as the additives in the set coating gradually increase or decrease gradually, the requirements are met. The gradient coated cigarette paper with positioning marks can be cigarette paper, wrapping paper or tipping paper, and in the process of actually making cigarettes from cigarette paper, only one of them can be used for cigarette paper, wrapping paper or tipping paper or several. Since the additives on the cigarette paper gradually increase or decrease, as the cigarette burns, the gradually coated functional additives make each puff of the cigarette close to or the same, weaken or The problem of mouth-to-mouth inconsistency of smoke is eliminated.

2. The positioning mark is a positioning hole punched by a laser. The positioning mark can not only identify the area to be coated, but also be sensed by the cigarette machine probe during the subsequent cigarette paper rolling and cigarette cutting process. Through the program It is set that the cigarette can be cut off at the positioning hole punched by the laser, and there will be no perforation on the cigarette product (cigarette), and there is no difference between the cigarette and the normal production cigarette.

3. Determine the area of the coating area and the type and proportion of the substance to be coated by manual evaluation and calculation, and set a number of coating holes on the cigarette paper coating roller, and the coating holes are connected to the coating material; A coating with additives gradually increasing or decreasing in a certain area is coated; the diameter of the coating holes on the coating roller is in the range of 0.02-0.15mm, and the number of holes in the holes is gradually changing in the range of 10-50 When the type and proportion of the material to be coated are determined, the diameter and number of holes on the coating roller can be adjusted appropriately, as well as the speed of the coating roller. In this way, the desired graded coated cigarette paper can be obtained. Therefore, the coating method is simple and suitable for industrial production.
