CN201182197Y - Vented Dilution Groove Filter Sticks - Google Patents

Abstract

The utility model discloses a ventilated dilution groove filter rod, which belongs to the technical field of cigarettes. Vented dilution grooved filter rods consist of tow material surrounded by perforated grooved paper wrapped around the centrally located tow material covered by a high sheer wrapper outside the high sheer molded paper Wrapped with perforated tipping paper. The grooves on the grooved paper are arranged vertically along the generatrix of the filter rod cylinder, or arranged at an angle of 20-60 degrees to the generatrix of the filter rod cylinder. The holes are uniformly or non-uniformly arranged on the grooved paper. The holes are uniformly or non-uniformly arranged on the tipping paper. The utility model has the advantages of reasonable design, simple structure and no cost increase. Ventilation holes are arranged on the grooved paper and the tipping paper to achieve the effect of high filtration and high ventilation, and can significantly reduce tar and other harmful components. It not only meets the industrial production of filter rods, but also meets the technical requirements of cigarette design, and makes a significant contribution to low-tar and low-hazard cigarettes.

Description

Vented Dilution Groove Filter Sticks

technical field

The utility model belongs to the technical field of cigarettes, in particular to a filter tip rod with grooved paper structure, good ventilation and excellent defocusing function.

Background technique

Cigarette ventilation filter sticks in the prior art are mostly single high-permeability acetate fiber tip sticks or grooved tip sticks, which cannot play a role of high dilution and high filtration for cigarettes, and cannot fully meet the design requirements of low-harm cigarettes.

Utility model content

Aiming at the above-mentioned deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a kind of ventilation and dilution grooved filter rod, which has the high filtration efficiency of grooved paper, and has the advantages of grooved paper holes and tipping paper holes. Ventilation and dilution function significantly reduces tar and other harmful components.

The technical scheme of the utility model is: the ventilation and dilution grooved filter rod contains tow material, the grooved paper with holes is wrapped outside the tow material located in the center, and the high-permeability forming paper is wrapped outside the grooved paper , Wrapped with perforated tipping paper outside the high-transparency molding paper. The grooves on the grooved paper are arranged vertically along the generatrix of the filter rod cylinder, or arranged at an angle of 20-60 degrees to the generatrix of the filter rod cylinder. The holes are uniformly or non-uniformly arranged on the grooved paper. The holes are uniformly or non-uniformly arranged on the tipping paper.

The utility model has the advantages of reasonable design, simple structure and no cost increase. Ventilation holes are arranged on the grooved paper and the tipping paper to achieve both ventilation and high filtering effect, and can significantly reduce tar and other harmful components. It not only meets the industrial production of filter rods, but also meets the technical requirements of cigarette design, and makes a significant contribution to low-tar and low-hazard cigarettes.

Description of drawings

Accompanying drawing 1 is the sectional structure diagram of an embodiment of the utility model.

The marks in the accompanying drawings are described as follows: 1-tipping paper; 2-holes; 3-high penetration forming paper; 4-holes; 5-grooved paper; 6-voids; 7-tow.

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail. As shown in Figure 1, the tow material 7 is wrapped with grooved paper 5, and the gap 6 formed between the corrugations on the grooved paper 5 forms an area of low pressure drop, so that smoke can easily pass through the area of low pressure drop And high-efficiency filtration occurs. The grooved paper 5 is wrapped with a high-transparency molding paper 3, and the high-transparency molding paper 3 is wrapped with a tipping paper 1. Grooved paper 5 of the present utility model is processed through pre-punching, is provided with uniform or uneven hole 4 on it, and tipping paper 1 is also punched, and hole 2 on it is evenly or unevenly arranged. The filter tip rod of the present utility model is made like this, first carries out laser or electrostatic punching 4 to special cellulose paper, then with special cellulose paper pressing groove structure, wraps silk with this groove paper 5 with hole 4 Bundle material 7, wrapping with high penetration forming paper 3 outside groove paper 5 again, the outermost layer is the tipping paper 1 of perforation. The filter tip rod of the utility model not only has the high filtration of grooved paper, but also has the ventilation and dilution of perforation, so it can effectively reduce coke and reduce harmful substances.
