A kind of filter tip with quality improving ring and cigarette

Abstract

The invention discloses a filter tip with a quality-improving ring and a cigarette. The filter tip with a quality-improving ring includes a filter rod and a tipping paper wrapped outside the filter rod and connecting the filter rod with a cigarette. There are several rows of perforations, which are distributed in parallel between the rows, and the perforations between the rows are aligned or staggered. One or more rows of perforations are provided with a quality-enhancing ring that completely blocks the perforations of the row. . The invention can not only ensure the ventilation rate of the cigarette when the cigarette is drawn to the second half, reduce the concentration of tar, nicotine and carbon monoxide in the smoke, but also avoid the defect of full-width punching of the tipping paper.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and in particular relates to a filter tip with a quality-improving ring and a cigarette. Background technique [0002] Cigarettes consist of a filter and a cigarette. The filter includes a filter rod and a tipping paper that wraps the filter rod and connects the filter rod to the cigarette. Existing tipping paper generally uses tipping paper, which is a special industrial paper and an important raw material for cigarette production. And so on step, filter stick is connected with cigarette at last. [0003] With the improvement of people's living standards and different health requirements, cigarette factories have proposed tar reduction and harm reduction to produce cigarettes with low tar content. There are two main methods to reduce the tar content of cigarettes, one is chemical tar reduction, and the other The first is physical focus reduction. The common technology for physical coke red...

Problems solved by technology

The common technology for physical coke reduction is filter ventilation, dilution and coke reduction. At present, various cigarette manufacturers use holes with a diameter of 0.05mm-0.4mm on the tipping paper to dilute and reduce coke; The small holes in the perforated tipping paper enter the cigarette and mix with the mainstream smoke, which dilutes the smoke and reduces the various chemical components in the smoke. Therefore, the degree of dilution of the smoke directly affects the cigarette product. The quality and the effect of reducing harmful components such as cigarette tar and carbon monoxide; because the smoke dilution is related to the pore size, the number of holes, the arrangement of holes and the uniformity of air permeability on the tipping paper, the tipping paper’s Air permeability and air permeability uniformity are crucial technical indicators for low-tar cigarette products. If the air permeability of tipping paper and forming paper is too high, the cigarette taste will become weak and the quality will decline; if the tipping paper is breathable If it is too low, the effect of reducing cigarette tar cannot be achieved; if the coefficient of variation of air permeability of tipping paper is too large, that is, the uniformity of air permeability of tipping paper is poor, the ventilation effect will be poor, the amount of cigarette tar will fluctuate greatly, and the quality of smoking will not be good. Stablize

[0004] The air permeability of common perforated tipping paper is generally 60~3000CU. There are two main types of perforation methods: electrostatic perforation and laser perforation. The number and position of electrostatic punching are strictly limited. The places where metal inks such as gold and silver are printed cannot be punched to avoid electric shock. Uneven distribution leads to large and unstable cigarette ventilation after cigarettes are produced. Although it has the effect of reducing harm, the taste of cigarettes is affected

[0005] Laser perforation is to punch one or two rows of laser holes with a laser in a specific area of ​​tipping paper, for example: "Tipping paper with double rows of laser holes, 201120442786.4", the present invention relates to tipping paper, tipping paper is a manufacturing The material of the cigarette is a kind of tipping paper with double rows of laser holes, including a tipping paper body, characterized in that: the tipping paper body has two rows of laser holes, and the laser holes are broken line structures , the distance between the double rows of laser holes is 2 to 3 mm. The tipping paper with single or two rows of laser holes has a disadvantage: when the cigarette is smoked in the first half, the air permeability is normal, but the cigarette is smoked In the second half, due to the high absorption of filter stick tar, the ventilation rate of cigarettes decreases, the degree of filtration of cigarette tar decreases, and the amount of air entering the filter tip is insufficient

Although the above scheme can better dilute the tar smoke and reduce the health hazards to smokers, the full-width punching of the tipping paper will inevitably affect its tensile strength, resulting in the risk of breaking when the cigarette is loaded on the machine; too high air permeability It will also make the smoking taste of the cigarette lighter and the quality lower; and so many holes will also have a certain impact on the appearance of the tipping paper
