Functional particle crepe paper coaxial filter stick

Abstract

A functional particle crepe paper coaxial filter stick relates to the technical field of cigarettes and comprises a filter element and wrapping layers, the filter element comprises an inner filter element (1) made of cellulose diacetate tows and an outer filter element (2) made of crepe paper, and the wrapping layers comprise an inner wrapping layer (3) and an outer wrapping layer (4). The inner wrapping layer (3), the outer filter element (2) and the outer wrapping layer (4) sequentially wrap the periphery of the inner filter element (1) from inside to outside to form a coaxial structure, and functional particles are mixed in the outer filter element (2) made of crepe paper. The coaxial filter stick made of the diacetate fiber tows and the crepe paper is low in draw resistance, high in hardness and better in cigarette tar filtering effect. The crepe paper is provided with creases which can more easily contain the granules, and compared with a traditional granule bar made of pure diacetate fiber tows, the crepe paper has the higher capacity of bearing the application amount of functional granules. By increasing the application amount of the functional particles, the action effect of the functional particles can be more remarkable, and the tar filtering effect is better.

Description

Technical Field

[0001] This utility model relates to the field of cigarette technology, specifically to a coaxial filter rod with crepe paper interspersed with functional particles. Background Technology

[0002] Existing cellulose acetate filter rods used in cigarette filter manufacturing suffer from poor tar filtration. While paper filter rods offer significantly improved tar filtration, their low rigidity negatively impacts the flavor of cigarettes and consequently, production efficiency and yield. Using functional particulate materials is currently a key method for enhancing the flavor of cigarette filters, offering advantages such as a large contact area with smoke and significant modification effects. However, due to their inherent structural limitations, it is difficult to directly incorporate substantial amounts of particulate material into either cellulose acetate or paper filter rods. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a coaxial filter rod with crepe paper containing functional particles.

[0004] The technical solution of this utility model is: a functional particle crepe paper coaxial filter rod, including a filter element and a wrapping layer. The filter element includes an inner filter element made of cellulose diacetate filaments and an outer filter element made of crepe paper. The wrapping layer includes an inner wrapping layer and an outer wrapping layer. The inner wrapping layer, the outer filter element, and the outer wrapping layer are wrapped around the inner filter element from the inside to the outside to form a coaxial structure. The outer filter element made of crepe paper also contains functional particles.

[0005] The technical advantages of this invention are as follows: the coaxial filter rod made of cellulose acetate tow and crepe paper has low draw resistance, high hardness, and better tar filtration. Because the crepe paper is a complete paper surface with folds that more easily accommodate granules, it has a greater capacity to hold the applied amount of functional granules compared to traditional granule rods made from simple cellulose acetate tow. By increasing the amount of functional granules applied, the effect of the functional granules can be made more significant, resulting in better tar filtration. The significantly increased hardness compared to ordinary crepe paper filter rods can effectively improve the yield rate in cigarette production. Attached Figure Description

[0006] Figure 1 This is a schematic diagram of the cross-sectional structure of this utility model. Detailed Implementation

[0007] like Figure 1As shown, a functional particle crepe paper coaxial filter rod includes a filter core and a wrapping layer. The filter core includes an inner filter core 1 made of cellulose diacetate filaments and an outer filter core 2 made of crepe paper. The wrapping layer includes an inner wrapping layer 3 and an outer wrapping layer 4. The inner wrapping layer 3, the outer filter core 2, and the outer wrapping layer 4 are sequentially wrapped around the inner filter core 1 from the inside out, forming a coaxial structure. The outer filter core 2, made of crepe paper, also contains functional particles. The inner filter core is made using low total denier cellulose diacetate filaments using a filter rod forming machine. A crepe roller with a certain pressure is used to crease the crepe paper. The crepe paper strip with embossing is then fed into a functional particle application device, allowing the functional particles to scatter and adhere in large quantities to the surface of the crepe paper. The crepe paper strip with the functional particles attached, the inner filter core with the inner wrapping layer, and the outer wrapping layer forming paper are fed together into a forming gun for subsequent filter rod forming processes.

[0008] The functional particles are activated carbon.

[0009] The diameter of the inner filter element 1 is 3 to 5 millimeters.

[0010] The outer diameter of the outer filter element 2 is 6 to 8 mm.

[0011] The inner wrapping layer 3 is a shaped paper.

[0012] The outer wrapping layer 4 is a shaped paper.
