Description
Technical Field
The invention relates to the technical field of heating cigarettes, in particular to a hollow three-section type heating cigarette and a manufacturing method thereof.
Background
The existing mainstream heating cigarettes mostly adopt a four-section structure or a five-section structure, and the production processes are as follows: and combining some functional sections to form a composite filter stick, twisting other functional sections and the composite filter stick together through tipping paper, and slitting to form cigarettes. For example, in some four-section structures, the smoking section, the supporting section and the cooling section are compounded to form the ternary composite filter stick, and finally the ternary composite filter stick is twisted and connected with the filtering section by using tipping paper to form the heated cigarette. In addition, as shown in fig. 1, there is also a four-segment structure, in the step (a), the support segment, the cooling segment and the filter segment are firstly combined to form the ternary composite filter stick 11, in the step (b), the ternary composite filter stick 11 and the tobacco segment 12 are twisted and connected by using tipping paper 13, online laser perforation (position shown by dotted line) can be carried out, in the step (c), the direction is adjusted and output after being cut, and in the step (d), the heated cigarette 14 is formed. In addition, the four-section structure is characterized in that the smoking section and the support section are compounded to form a binary composite filter stick, the cooling section and the filter section are compounded to form a binary composite filter stick, and finally the binary composite filter stick and the binary composite filter stick are twisted and connected by tipping paper to form a heated cigarette. Even in a three-section structure, the cigarette is formed by twisting and connecting one functional section and a binary composite rod formed by compounding two functional sections through tipping paper to form the heated cigarette.
In summary, under the same length, the four-segment structure results in the length of each segment that can be distributed being shortened, which brings direct influence to the reduction of production efficiency. The twisting and connecting process which is the same as that of the traditional cigarette needs to wrap and then splice two materials (functional sections) through a connecting paper (tipping paper), and the quality problems caused by the twisting and connecting process comprise cigarette air leakage (air leakage caused by the fact that the connecting part of a filter tip and a cigarette is not glued or is not firmly glued), easy formation of gaps between the two materials and the like. If the mode of twisting and connecting the tobacco section and the ternary composite filter stick is adopted, because the tobacco section of the heated cigarette is shorter, a part of the tipping paper is left on the tobacco section, the appearance of the cigarette is poor, and even because the tipping paper wrapped on the tobacco section has circumference gain, the coupling of the heated cigarette and the smoking set is influenced.
