Embodiment Construction

[0024] Such as figure 1 , figure 2 As shown, the present invention provides a ring-shaped cut-off nozzle rod, which is composed of tow mandrel 5 and outer wrapping forming paper 4, and a layer of wrapping tow is arranged between tow mandrel 5 and forming paper 4. The inner layer paper 1 of the mandrel, the inner layer paper 1 is pre-set with 7 circuit breaking rings surrounding the tow mandrel, each circuit breaking ring is composed of three transverse grooves 2 arranged along the circumference of the tow mandrel, each A group of small drainage holes 3 are respectively provided on both sides of each transverse groove, and the number of small drainage holes is 1-500. In the range of 0.01-1.0MM. The longitudinal cross-sectional shape of the transverse groove is circular.

[0025] Transverse grooves 2 and drainage holes 3 such as image 3 As shown, the transverse groove 2 compresses the tow mandrel 5 toward the center to increase the center density, forcing part of the smoke...

Abstract

The invention relates to an annular break blocking filter rod. The annular break blocking filter rod consists of a bundle mandrel (5) and forming paper (4) enwrapping the outer layer of the bundle mandrel and is characterized in that: a layer of lining paper (1) enwrapping the bundle mandrel is arranged between the bundle mandrel and the forming paper; 1 to 10 break rings surrounding the bundle mandrel are arranged on the lining paper (1); each break ring consists of at least one transverse groove (2) peripherally formed along the bundle mandrel; and a group of drainage pores (3) are formed on the two side surfaces of each transverse groove respectively. The annular break blocking filter rod has the advantages that: the groove extrudes the bundle toward the axis so as to increase the density of the bundle and improve the longitudinal blocking efficiency to a certain extent; and part of smoke S enters the groove from the drainage pores and is subjected to transverse blocking twice in the groove area and condensed so as to further block the smoke completely and comprehensively and improve the blocking efficiency of the fiber type filter rod greatly.

Description

technical field [0001] The invention relates to tobacco products, in particular to a filter fiber type mouth stick for cigarettes. Background technique [0002] The mechanism of the fiber-type mouthpiece to remove particulate matter in the flue gas is mechanical filtration, and its filtration efficiency is related to the size (mass and diameter) of the particles in the flue gas, the movement speed of the particles, and the degree of diffusion of the particles in the fiber (distribution and residence time). Due to the very short time (0.04 seconds) for the particles to pass through the nozzle rod, the diameter of the particles is very small (0.2 microns), while the diameter of the filaments (20 microns) is 100 times larger than the diameter of the particles. Therefore, the mechanical filtration (retention) rate of particles caused by the fibers of the nozzle rod is very small. [0003] The mechanical filtration of fiber-shaped nozzle rod is to make the particles collide wit...
