Description
Technical Field
The invention relates to the technical field of tobacco products, in particular to double-layer composite cigarette paper and a preparation method thereof.
Background
With the progress of the rolling technology, along with the product diversification brought by the cigarette product market segment, the tobacco harm reduction technology and the new technology of the low-temperature heating non-combustion cigarette product, the cigarette paper directly participating in combustion in common cigarettes or heating non-combustion cigarettes together has very important direct contribution to the taste, the smoke components and the like of the cigarette products.
Most of the existing cigarette paper is used in a single layer in a reel form, and is wound on a cigarette rolling device according to a preset mode and then is conveyed to a tobacco shred input channel, then the tobacco shred is wrapped by the outer circumference of the tobacco shred together with the tobacco shred conveyed by one side, and the tobacco shred is conveyed to a tobacco gun channel and is glued on the lap edge of the cigarette paper to form a continuous tobacco rod for a subsequent cutter mechanism to cut to form a semi-finished cigarette.
In some cigarette manufacturing processes where the composition or flavor of the cigarette is controlled to be better, the double-layer cigarette paper on one cigarette is wrapped by changing the supply system of the cigarette paper. For example, a group of paper feeding mechanisms are added in the existing rolling equipment or the paper feeding mechanism of the existing cigarette equipment is improved to form a mode that single-layer cigarette paper of two discs can enter a cut tobacco input channel together at the same time, and the double-layer cigarette paper is used for wrapping cut tobacco. Through the matching of the two cigarette papers with the same or different performances, the functions of better taste, lower side-stream smoke or (and) more beautiful cigarette effect and the like are realized.
However, the double-layer cigarette paper threading and feeding system needs to redesign and purchase rolling production equipment or greatly modify the existing backup paper feeding system on the cigarette making machine so as to continuously feed the double-layer cigarette paper to prepare cigarette cigarettes with specific functions. The mode that two single disks of cigarette paper are respectively supplied is adopted, so that requirements such as synchronization of two sets of paper feeders of cigarette equipment are required, requirements which cannot be greatly different are provided for the performances (such as physical and chemical indexes such as thickness, tensile strength and the like) of the two single disks of cigarette paper, and otherwise, the problems of asynchronization of supply, easy breakage of one disk, poor lap bonding, poor cigarette appearance and the like exist; therefore, certain limitation conditions are brought to the mode of using the double-layer cigarette paper simultaneously, and the production and popularization of the cigarette are limited.
In order to meet the requirement of mass production of cigarettes with double-layer cigarette paper, a method for simply compounding two layers of paper rolls with different performances together is also provided, but after the two layers of cigarette paper are compounded together in the process of rolling into a round cigarette, the compounding is finished after glue is applied in a planar state, the thickness of the paper is increased, the inner layer and the outer layer of the compound paper curled in the rolling process are different in circumference, when the tobacco shreds are wrapped and rolled into the cigarette, the problem of cigarette rolling is often caused due to the fact that the inner layer and the outer layer of the compound paper are different in circumference and the inner layer and the outer layer are compounded together, the indexes such as the appearance and the circumference of the cigarette are not in accordance with the requirements, the quality accident of cigarette bursting is seriously caused, and the yield of the cigarette is further improved; therefore, the directly compounded double-layer cigarette paper can only be used in the occasions with thinner inner layer or outer layer and better elasticity; the cigarette paper compounded by simple gluing has no function of ventilating the middle layer, and has no difference between cigarettes with low sidestream smoke or improved taste and basic single-layer cigarette paper, so the simple compounded double-layer cigarette paper does not really get practical application in the actual cigarette production, and only stays in the experimental or theoretical discussion of a small sample.

unfolding the inner-layer paper raw material, and then coating a plurality of groups of glue line groups on the outer surface of the inner-layer paper raw material at equal intervals, wherein the glue line groups comprise two glue lines which are overlapped in parallel; a blank part is arranged between the adjacent glue line groups; the width of one glue line group plus the width of one blank part is equal to the width of the single-disk cigarette paper; when the glue line group is coated, reserved cutting parts are reserved on two sides of the inner-layer paper raw material, and the width of each reserved cutting part is smaller than that of the single-disk cigarette paper; aligning the outer layer paper raw material with the inner layer paper raw material, and bonding the outer layer paper raw material with the inner layer paper raw material through the glue line group on the inner layer paper raw material to obtain a cigarette paper raw material; and then cutting the cigarette paper raw material into a plurality of parts along the central line of each glue line group, cutting off the reserved cutting part during cutting, and respectively winding the cut parts into a disc shape to obtain the single-disc cigarette paper for rolling cigarettes. The glue layer coating mode is shown in figure 4, a part of glue layer is omitted, the width of an inner layer paper raw material in the figure is L (the size of the outer layer paper raw paper is the same as that of the inner layer paper raw paper), the width a of a single-disk cigarette paper is B, n is the number of the cigarette paper capable of being cut, A is a glue layer coating area, B is a boundary (cutting line) of two glue layers, the width of the glue layer is e/2, the width of the glue layer group is e, the width of the glue layer is based on the principle that the inner layer material and the outer layer material can be reliably bonded together after being cut, and the glue application amount is minimum.
Obviously, the outer paper stock can also be used as a base, and when the outer paper stock is used as a base, the preparation method comprises the following steps:
when the outer layer paper raw material is taken as a basis, the outer layer paper raw material is unfolded, then a plurality of groups of glue line groups are coated on the inner surface of the outer layer paper raw material at equal intervals, and each glue line group comprises two glue lines which are overlapped in parallel; a blank part is arranged between the adjacent glue line groups; the width of one glue line group plus the width of one blank part is equal to the width of the single-disk cigarette paper; when the glue line group is coated, reserved cutting parts are reserved on two sides of the outer-layer paper raw material, and the width of each reserved cutting part is smaller than that of the single-disk cigarette paper; aligning the outer layer paper raw material with the inner layer paper raw material, and bonding the outer layer paper raw material and the inner layer paper raw material through the glue line group on the outer layer paper raw material to obtain a cigarette paper raw material; then cutting the cigarette paper raw material into a plurality of parts along the central line of each glue line group, and cutting off the reserved cutting part during cutting to obtain the single-disk cigarette paper for rolling the cigarettes.
In this embodiment, although it is different from the embodiment 1 in which only one side is adhered, the cigarette paper is adhered to both sides in the length direction of the cigarette, and there is a problem that the inner and outer layers of the cigarette paper are deformed differently due to the difference in circumference after being rolled into a circumference; in practice, however, because the inner layer can be made of a material with relatively small thickness and relatively poor strength or strong deformability, and the outer layer can be made of a material with relatively large thickness and relatively good strength, the diameter of the curling circumference of the composite cigarette paper (the actual curling circumference of the two layers of combined cigarette paper) is actually determined by the material of the outer layer with relatively large thickness and relatively good strength when the rolling task is performed on the cigarette making machine; the inner layer material is not consistent with the part which is not adhered after being curled, but can be randomly crumpled and deformed in the circumferential direction of the cigarette circumference without overlapping because the inner layer material is thin and poor in strength and is not adhered with the outer layer material at the position where the cigarette is not overlapped, so that the cigarette cannot be directly reflected on the cigarette paper with a thicker outer layer of the rolled cigarette, the quality of the rolled cigarette cannot be influenced, and the practical significance is realized; on the other hand, compared with the existing full-adhesive-face composite double-layer cigarette paper, the crease or deformation of the inner-layer paper also occupies a part of the cigarette section area which is not large, so that the filling of the tobacco shreds wrapped inside can be reduced by a small part; thus not only being beneficial to the production enterprises to slightly reduce the cost, but also being beneficial to reducing harmful ingredients (because the actual filling amount of the tobacco shreds is reduced) when the cigarettes are smoked, and not affecting the appearance quality of the circumference of the cigarettes; the use amount of the adhesive is reduced in the process of actually compounding the inner layer paper material and the outer layer paper material, and the sucked smoke is not greatly influenced, so that the method is a practical, usable and easy-to-use embodiment.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
