Description

A kind of transparent cavity filter rod cigarette processing method Technical field

The invention belongs to the technical field of tobacco, and specifically relates to a transparent cavity filter rod cigarette processing method.

Background technique

As the competition in the cigarette market becomes increasingly fierce, cigarette products with novel appearance and special functions are favored by consumers. Filter rods are an important part of cigarettes, especially cavity composite filter rods. The filter rods have a unique and novel appearance. Inside the cavity, activated carbon can be added, or aroma-carrying plant particles, explosive beads, etc. can be added for a long time. of fragrance-enhancing and moisturizing materials. The use of transparent cavity filter rods can not only directly observe the internal structure of the cavity, but also add functional materials inside the cavity to achieve various functions such as flavoring and moisturizing.

For transparent cavity filter rod cigarettes, since the tipping paper and forming paper made of transparent materials are very different from conventional cigarettes in water absorption, water blocking, bonding performance, and temperature resistance, so when rolling and tipping on the machine, all The lap glue and splice glue used, as well as the parameter settings of the rolling and splicing machines, processing intensity, production speed, etc. are very different from ordinary acetate fiber filter rods. Conventional cigarette processing methods are used to produce transparent cavity filter rod cigarettes. Due to the difference in paper materials between transparent tipping paper and ordinary tipping paper, especially the characteristics of transparent tipping paper and transparent molding paper are greatly affected by temperature changes, they are rubbed in the tipping machine. The temperature setting of the operating area where filter rods, cigarettes and other equipment are connected, especially the connecting plate of the connecting paper, has a great influence on the operation. The temperature is designed to be too high. Because the transparent connecting paper and the forming machine are greatly deformed due to the influence of temperature, the bonding performance is deteriorated. If the tipping paper is large, the splicing paper is prone to adhesion, causing the cigarettes to stick. If the cigarettes are more adherent, they may even block the washboard of the splicing machine, causing the splicing machine to shut down. When the temperature is designed to be low, the splicing paper and the cigarettes will be stuck together. When filter rods are installed, the bonding performance of the splice glue decreases, and it cannot effectively bond the filter rods or cigarettes, causing air leakage in the cigarettes or weak overlapping, and the cigarettes are prone to bursting and air leakage. In addition, because the temperature at the washboard is related to the running speed of the cigarette, ordinary splicing paper is subject to very little temperature change, and the splice glue is not easily affected. The running speed of the cigarette will basically not affect the splice glue bonding and splicing performance. However, the temperature setting of the washboard for processing the transparent cavity filter rod cigarettes obtained by using the existing technology is not easy to match the running speed of the cigarette, and the heat loss of the washboard is not easy to match the heat compensation, which can easily lead to equipment failure, shutdown, low processing efficiency or even abnormality. Continuous and stable production.

In summary, the bonding performance of transparent splicing paper, molding paper, and splice glue is greatly affected by temperature. If the temperature is too high, the splicing paper will easily stick. If the temperature is too low, the splice performance will decrease and the splice will not be strong. Resistance to the temperature of the washboard of the splicing machine is a key process. When the transparent splicing paper is spliced at the washboard, the running of the cigarettes will take away a lot of heat, which affects the temperature of the washboard. When the running rate of cigarettes reaches more than 4000 cigarettes/minute, the heat compensation of the washboard is slow. , the temperature of the washboard decreases quickly. If the temperature of the washboard cannot be continuously stabilized, it will easily cause problems with the bonding of the tipping paper. Therefore, the temperature setting of the washboard must match the running speed of the cigarette. In order to achieve continuous and stable operation, the temperature of the washboard will change little and will not cause problems with the tipping paper. Adhesion, the bonding performance of the splice glue will decrease, and the splice paper will not be firmly bonded.

The present invention is proposed to solve the above problems.

Detailed ways

The present invention will be further described below through examples, but it is not limited to this example. Experimental methods without specifying specific conditions in the examples usually follow conventional conditions and the conditions described in the manual, or use general equipment, materials, reagents, etc. according to the conditions recommended by the manufacturer. Unless otherwise specified, all can be obtained from Obtained through commercial means. The raw materials required in the following examples and comparative examples are all commercially available.

Example: Rolling of transparent cavity filter rod cigarettes

1. Design of tipping paper and forming paper

The transparent tipping paper and transparent molding paper of the present invention do not use plastic films, but are degradable paper-based environmentally friendly films produced mainly from modified starch, polylactic acid fiber and other materials. The ash and smell produced after burning are the same as those after burning paper. Due to its film characteristics, it is particularly suitable for the production of high-end plugging paper with clear and beautiful images. In order to improve the bonding effect and smoothness between the tipping paper and the forming paper and avoid wrinkles in the tipping paper, the physical index of the transparent tipping paper is quantitatively controlled at 40-90g/m ² , preferably 50-80g/m ² ; the thickness is 0.2-0.3mm, preferably 0.25mm; longitudinal tensile strength ≥2.0KN/m, elongation ≥15.0%.

The quantitative control of transparent forming paper is 40-50g/m ² , and the other indicators are consistent with those of transparent tipping paper. The higher the basis weight of the transparent molding paper, the higher the molding effect and appearance recovery ability after pinching the beads, but the cost per unit area also increases.

2. Process design of rolling and splicing machines

The feed alarm value is 800-1200; the rolling start speed is 300-500 pieces/minute, and the rolling target speed should be 3000-8000 pieces/minute. Because an excessively high cigarette rolling speed (more than 5,000 cigarettes/minute) will quickly take away the heat at the washboard of the splicing machine, causing the temperature of the washboard to drop rapidly, thus affecting the bonding effect of the transparent splicing paper. Rolling should be slow and steady from startup to target speed. From 0 to normal and smooth production, it should be controlled within 2-3 minutes to prevent excessive changes in rolling speed, excessive heat transfer in the temperature of the soldering iron and the washboard, resulting in lap joints. 2. The tip glue is not able to bond effectively, which affects the bonding effect of the tip paper and causes the cigarette to leak or burst.

The temperature of the first soldering iron, the second soldering iron, and the setting of the washboard temperature need to be determined by the target speed of rolling: the relationship between the first soldering iron temperature T ₁ and the target speed V of rolling is T ₁ =V/60+150, T ₁ range is between 200-300℃; the relationship between the second soldering iron temperature T ₂ and the rolling target speed V ₁ is T ₂ =V/80+190, T ₂ range is between 230-300℃; the washboard temperature T The relationship between ₃ and the rolling target speed V is T ₃ =V/100+200, and the range of T ₃ is between 220-280°C.

According to the characteristics of transparent tipping paper that is not easy to bond, the temperature is higher than that of conventional cigarette processing. On the one hand, high temperature can properly soften the transparent patching paper, on the other hand, it can improve the contact performance between the transparent patching paper and the splice glue, and improve the bonding performance of the splice glue.

3. Design of high temperature resistant water-based glue (including joint glue and lap glue)

Due to the different bonding characteristics of transparent tipping paper, formed paper and ordinary tipping paper, it is necessary to select a tip glue and lap glue that are effective in bonding and do not affect the sensory quality of cigarettes. During the cigarette rolling process, on the one hand, the processing parameters of the rolling and splicing machines are adjusted, and at the same time, parameters such as the temperature of the washboard, the temperature of the first soldering iron and the second soldering iron, which are closely related to the splicing paper, are adjusted in the splicing machine part; on the other hand, In terms of selection, the appropriate temperature resistance and bonding performance of the lap glue and splice glue should be selected to ensure that the joints of the cigarettes are tightly bonded and the cigarettes will not explode or leak. At the same time, the surface of the bonding joints is required to be smooth. Spend. The selected joint glue should appropriately increase the proportion of solid content and temperature resistance of the water-based glue, control its pH to 5.5-7.0, preferably 6.0; solid content 50-55wt%, preferably 52wt%; viscosity 4000-5000mPa.s; increase its Temperature resistance and bonding properties.

Since the high-temperature resistant lip glue participates in the burning of cigarettes, its temperature resistance and bonding performance are mainly improved through processing technology adjustments, which will not affect the sensory quality of cigarettes; the pH of the lip glue is selected to be 5.0-6.0, preferably 5.5; the solid content is 45- 55wt%, preferably 50wt%; viscosity 850-1000mPa.s.

4. Rubber roller design

The number of gluing areas of the rubber roller is 3-8; the thickness of the upper front edge of the non-cavity area is 0.010-0.015mm, and the gluing thickness of the rubber roller in the cavity area is 0.020-0.030mm. The thickness of different upper areas should be smooth. , the gluing method adopts full glue.

According to the transparent cavity filter rod cigarette processing method of this embodiment, the cigarette processing can run continuously and stably, and the temperature of the washboard changes little, which will not cause adhesion of the tipping paper, nor will it cause the tip glue to reduce the adhesive performance of the tipping paper. The problem of weak bonding. The photo of the transparent cavity filter rod cigarette obtained in this embodiment is shown in Figure 1. The cigarette has no wrinkles or cracks, the joints are tightly bonded, and there is no air leakage during smoking. The smoking methods of transparent cavity filter rod cigarettes can be divided into two smoking methods: pinching and popping the popping beads before smoking and pinching and popping the popping beads during smoking. The smoker squeezes the popping beads to release the aroma-causing substances wrapped in the popping beads, turning them into side-flow smoke with a special flavor and entering the mouth together with the mainstream smoke passing through the filter to change the flavor of the cigarette and enhance smoking. Absorb quality effect.

However, the processing using the existing technology method is unstable and can easily cause equipment failure, shutdown, low processing efficiency and even the inability to produce normally and continuously stably. The transparent cavity filter rod cigarettes obtained had wrinkles, variability, cracks, and air leakage.

Comparison of results between the method of the present invention and the method of the prior art:

After the transparent cavity filter rod cigarettes obtained by the method of the present invention have been placed for 6 months, the cigarettes still have no wrinkles and cracks, and there is no air leakage when smoking.
