Description
Technical Field
The invention belongs to the technical field of tobacco, and particularly relates to a method for processing a cigarette with a transparent cavity filter stick.
Background
With the increasingly intense competition of cigarette market, cigarette products with novel appearance and special functions are favored by consumers. The filter stick is used as an important component of a cigarette, particularly a composite filter stick with a cavity, the filter stick is unique and novel in appearance, and active carbon can be added into the cavity, or one or more aroma-increasing and moisture-keeping materials with long-term aroma-increasing modes such as aroma-increasing plant particles and bead blasting can be added into the cavity. By adopting the transparent cavity filter stick, the internal structure of the cavity can be directly observed, and various effects of increasing aroma, keeping moisture and the like can be achieved by adding functional materials in the cavity.
The tipping paper and the forming paper made of transparent materials have great differences from the conventional cigarettes in water absorption, water resistance, bonding performance and temperature resistance, so when the cigarette is rolled and tipped on a machine, the lap joint glue and the tipping glue used, the parameter settings, the processing strength, the production speed and the like of the rolling and tipping machine are greatly different from those of the common acetate fiber filter stick. The cigarette with the transparent cavity filter stick is produced by adopting a conventional cigarette processing method, because the characteristics of transparent tipping paper and common tipping paper, particularly the characteristics of the transparent tipping paper and transparent forming paper, are greatly changed by temperature change, the temperature setting of equipment running positions of twisting filter sticks, cigarettes and the like of a tipping machine, particularly a tipping paper twisting connecting plate, has great influence on the running, the temperature design is overhigh, the transparent tipping paper and a forming machine are greatly deformed by the temperature influence, the bonding performance is increased, the tipping paper is easy to be bonded, the cigarette adhesion is caused, more cigarettes are bonded, and even the twisting plate position of the tipping machine is blocked, so the tipping machine is stopped; when the temperature design is low, when the tipping paper is used for tipping the cigarette and the filter rod, the adhesive property of the tipping glue is reduced, the filter rod or the cigarette cannot be effectively adhered, the cigarette is subjected to air leakage or is not firmly lapped, and the cigarette is easy to explode and leak. In addition, because the temperature at the washboard is related to the cigarette running speed, the common tipping paper is very small in temperature change, the tipping glue is not easily influenced, and the cigarette running speed basically does not influence the binding and tipping performance of the tipping glue. The temperature setting of the washboard for processing the transparent cavity filter stick cigarettes obtained by the method in the prior art is not easily matched with the cigarette running speed, the heat loss of the washboard is not easily matched with the thermal compensation, equipment failure and machine halt are easily caused, and the processing efficiency is low or even normal continuous and stable production cannot be realized.
In conclusion, the adhesive bonding performance of the transparent tipping paper, the forming paper and the nozzle is greatly influenced by temperature, the tipping paper is easy to adhere when the temperature is too high, the adhesive bonding performance of the nozzle is reduced when the temperature is too low, and the tipping is not firm. The temperature of a washboard of a splicing machine is a key process, when transparent tipping paper is spliced at the washboard, a large amount of heat can be taken away by cigarette operation, the temperature of the washboard is influenced, when the cigarette operation speed reaches more than 4000 cigarettes/min, the washboard thermal compensation is slow, and the washboard temperature is reduced quickly. If the temperature of the washboard cannot be continuously stabilized, the problem of splicing of the tipping paper is easily caused, so that the temperature of the washboard must be matched with the running speed of the cigarettes, and when the cigarette is continuously and stably run, the temperature change of the washboard is small, the splicing paper cannot be adhered, the adhesive property of the tipping glue cannot be reduced, and the splicing paper cannot be adhered firmly.
The present invention has been made to solve the above problems.

Detailed Description
The present invention is further illustrated by the following examples, but is not limited to these examples. The experimental methods not specified in the examples are generally commercially available according to the conventional conditions and the conditions described in the manual, or according to the general-purpose equipment, materials, reagents and the like used under the conditions recommended by the manufacturer, unless otherwise specified. The starting materials required in the following examples and comparative examples are all commercially available.
Example (b): transparent cavity filter stick cigarette rolling system
1. Tipping paper, forming paper design
The transparent tipping paper and the transparent forming paper of the invention do not adopt plastic films, but adopt materials such as modified starch, polylactic acid fiber and the like as main bodies to produce degradable paper-based environmental protection films. The burnt paper ash and the generated smell are not different from the burnt paper. Because of the characteristic of the film, the method is particularly suitable for producing high-grade tipping paper with clear picture quality and delicacy. In order to improve the bonding effect and the smoothness between the tipping paper and the forming paper and avoid the tipping paper from wrinkling, the physical index quantification of the transparent tipping paper is controlled to be 40-90g/m2Preferably 50 to 80g/m2(ii) a A thickness of 0.2-0.3mm, preferably 0.25 mm; the longitudinal tensile strength is more than or equal to 2.0KN/m, and the elongation is more than or equal to 15.0 percent.
The quantitative ratio of the transparent forming paper is controlled to be 40-50g/m2And the other indexes are consistent with those of the transparent tipping paper. The higher the basis weight of the transparent molding paper, the higher the molding effect and the appearance restoration ability after bead pinching, but the higher the cost per unit area.
2. Processing process design of rolling and splicing machine
The feed alarm value is 800-1200; the rolling starting speed is 300-8000 counts/min, and the rolling target speed is 3000-8000 counts/min. Because the heat at the washboard of the tipping machine can be quickly taken away at an excessively high cigarette rolling speed (more than 5000 cigarettes/min), the temperature of the washboard is quickly reduced, and the bonding effect of the transparent tipping paper is influenced. The rolling speed is slowly and stably excessive from the starting speed to the target speed, the rolling speed is controlled to be 2-3 minutes from 0 to normal and stable production, and the phenomenon that lap glue and mouth connecting glue cannot be effectively bonded to influence the bonding effect of tipping paper to cause air leakage or opening explosion of cigarette cigarettes due to the fact that the rolling speed is changed too fast, the soldering iron temperature and the heat transfer at the washboard are too fast is prevented.
The temperature of the first and second soldering irons, and the setting of the washboard temperature need to be determined by the target speed of the rolling: first iron temperature T1The relation V with the target speed of rolling is T1＝V/60+150，T1The range is between 200 ℃ and 300 ℃; temperature T of the second iron2With the target speed V of the roll1The relationship is T2＝V/80+190，T2The range is between 230 ℃ and 300 ℃; washboard temperature T3The relation V with the target speed of rolling is T3＝V/100+200，T3The range is between 220 ℃ and 280 ℃.
The temperature is higher than that of the conventional cigarette processing process according to the characteristic that the transparent tipping paper is not easy to bond. The high temperature can improve the transparent tipping paper of suitable softening on the one hand, on the other hand can improve the contact performance of transparent tipping paper and nozzle glue, improves the adhesive property that the nozzle glues.
3. Design of high-temperature-resistant water-based adhesive (including connector adhesive and lap joint adhesive)
Due to different characteristics of the transparent tipping paper, the forming paper and the common tipping paper in the aspect of bonding, a tipping glue and a lap glue which are effectively bonded and do not influence the sensory quality of cigarettes need to be selected in a targeted manner. In the cigarette rolling process, on one hand, the processing technological parameters of a rolling and tipping machine are adjusted, and simultaneously parameters such as washboard temperature closely related to tipping paper in a tipping machine part, the temperature of a first soldering iron and a second soldering iron and the like are adjusted; on the other hand, the proper temperature resistance and the bonding performance of the lap joint glue and the connector glue are selected, so that the joint of the cigarettes is tightly bonded, the cigarettes cannot generate opening explosion and air leakage, and the surface smoothness of the bonding part is required. The selected nozzle glue properly improves the proportion of the solid content of the water-based glue and the temperature resistance, and controls the pH value to be 5.5-7.0, preferably 6.0; solids content of 50-55 wt.%, preferably 52 wt.%; viscosity 4000-5000 mPa.s; the temperature resistance and the bonding performance of the adhesive are improved.
The high-temperature resistant lap adhesive is mainly adjusted by a processing technology to improve the temperature resistance and the adhesive property of the high-temperature resistant lap adhesive due to participation in cigarette combustion, and the sensory quality of cigarettes cannot be influenced; selecting a lap adhesive pH of 5.0-6.0, preferably 5.5; solids content of 45 to 55 wt.%, preferably 50 wt.%; viscosity 850-1000 mPas.
4. Rubber roller design
The number of the gluing areas of the gluing roller is 3-8; the thickness of the front on the non-cavity area is 0.010-0.015mm, the gluing thickness of the rubber roller on the cavity area is 0.020-0.030mm, the thicknesses of different upper areas are gradually increased, and the gluing mode adopts full glue.
According to the cigarette processing method with the transparent cavity filter stick, cigarette processing can be continuously and stably operated, the temperature change of the washboard is small, the tipping paper cannot be adhered, and the problem that the tipping paper is not firmly adhered due to the fact that the adhesive property of the tipping glue is reduced is solved. The picture of the transparent cavity filter stick cigarette obtained in the embodiment is shown in figure 1, the cigarette has no wrinkles and no explosion, and the bonding of the connecting part is tight; there is no air leakage during pumping. The smoking mode of the transparent cavity filter stick cigarette can be divided into two smoking modes of breaking and exploding beads before smoking and breaking and exploding beads during smoking. The puffing bead is squeezed by a smoker to release the aroma substances wrapped in the puffing bead, so that the puffing bead becomes sidestream smoke with special aroma and enters the oral cavity together with mainstream smoke passing through the filter tip, thereby achieving the effects of changing the aroma of the cigarette and improving the smoking quality.
The method in the prior art is unstable in processing, easy to cause equipment failure and halt, low in processing efficiency and even incapable of normal continuous and stable production. The obtained cigarette with the transparent cavity filter stick has the phenomena of folds, changeability, burst and air leakage.
The results of the method of the invention compared with the prior art method:
after the transparent hollow filter stick cigarette obtained by the method is placed for 6 months, the cigarette still has no wrinkle and no air leakage during smoking.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
