Description
Technical Field
The invention belongs to the technical field of tobacco, and particularly relates to a one-step forming device and a one-step forming method for a filter stick with a binary composite structure.
Background
The cigarette filter tip, especially the special filter tip, plays an important role in reducing harm and tar of the cigarette. The special filter stick can be divided into a common filter stick (unit filter stick) and a filter stick with a binary, ternary or multi-element composite structure according to the structure. The current perfuming types are various, such as gel, glyceryl triacetate, incense thread, incense tablet, particle, bead explosion and the like. In order to avoid the direct contact of the flavoring substance with the oral cavity, the flavoring section is generally arranged at the middle section of the composite structure filter stick or the front section of the composite structure filter stick, such as the far lip end of the binary composite structure filter stick.
Because the structure of the flavoring filter stick is different from that of the common unit filter stick, the processing technology of the flavoring filter stick is obviously different from that of the common filter stick. In the production steps of the filter stick with the perfuming composite structure in the prior art, the filter stick with the perfuming composite structure can be generally processed to be a filter stick with the perfuming composite structure, such as a perfuming thread, a perfuming sheet and the like, and then the filter stick is subjected to multi-component compounding with an acetate fiber filter stick on a forming machine, so that the filter stick with the composite structure, of which the middle section or the front section is provided with a spice section, can be processed.
The production of the composite structure filter stick in the prior art can be obtained by two or more steps, and the more the composite units are, the more the number of layers of the required plug paper is; the filter stick with the binary composite structure generally needs two times of forming paper for compounding the filter stick; because the number of the layers of the plug wrap paper is large, in order to achieve the ventilation and dilution functions of the filter stick, the air permeability of the filter stick plug wrap paper is generally over 10000CU, and the processing cost of the filter stick is increased. In addition, because the compounding ratio of the filter stick is fixed, the forming machine needs to be modified when the compounding ratio of the filter stick is adjusted, and all set parameters of the forming machine need to be completely changed; therefore, the forming paper is wasted, the process flow is complex, the processing time of the filter stick with the composite structure is prolonged, and the forming work efficiency of the filter stick with the composite structure is low.
The present invention has been made to solve the above problems.
