Detailed ways

The following embodiments further illustrate the content of the utility model in conjunction with the accompanying drawings, rather than further limiting the protection scope of the utility model.

Example 1

After the corn cob core particles and xanthan gum are mixed evenly according to the mass ratio of 100:8, they are extruded by molding equipment, cut and polished into cylindrical filter rods with the same diameter as ordinary filter rods, and further on the central axis, Use a drill to drill a cylindrical through hole. The cross-sectional area of the round hole is 30% of the cross-sectional area of the filter rod. Finally, the cross-section is cut into a cylinder with a length of 84mm to obtain the hollow filter rod unit section. Then compound it with an ordinary cellulose acetate filter rod with a length of 126 mm; a binary compound cigarette filter tip is obtained.

The external structure of the filter tip is shown in Figure 3, and the cross-section of the hollow filter rod unit section is shown in Figure 1. A filter rod unit segment composed of corn cob granular material. The cellulose acetate filter rod unit section is wrapped with inner-wrapped molding paper, and the acetate fiber filter rod unit section wrapped with the inner-wrapped molding paper is connected with the corn cob granular material unit filter rod section, and then packaged into one body by the outer-wrapped molding paper to form a filter tip. The filter rod unit section of the corncob granular material is formed by accumulating corncob particles of 20 to 40 meshes through the adhesion of an appropriate amount of xanthan gum. The cross-section of the filter rod unit section of the corn cob granular material is circular, and the cross-sectional area of the circular hole is 30% of the cross-sectional area of the filter rod. The filter rod unit segment of the corn cob granular material is set as the contact end between the filter tip and the shredded tobacco of the cigarette.

This kind of binary composite filter has the excellent performance of similar binary composite rods, and can save a lot of expensive and scarce resources of cellulose acetate for cigarettes. Promotional value; corn cob particles have a loose porous structure and good adsorption performance. At the same time, there are a large number of gaps between the assembled hollow mandrel particles, which is more conducive to the diffusion of smoke, thus achieving a good effect of reducing coke and harm.

Example 2

Mix pomelo peel granules and modified starch evenly at a mass ratio of 100:3, extrude them with molding equipment, cut and grind them into cylindrical filter rods with the same diameter as ordinary filter rods, and further use Drill a cylindrical through hole, and then use a file to process it into a heart-shaped through hole. The cross-sectional area of the heart-shaped cross-section is 70% of the cross-sectional area of the filter rod. Finally, the cross-section is cut into a cylinder with a length of 120mm to obtain a hollow filter rod. unit segment. It is then compounded with an ordinary cellulose acetate filter rod with a length of 120 mm to obtain a binary composite cigarette filter tip.

The external structure of the filter tip is shown in Figure 3, and the cross-section of the hollow filter rod unit section is shown in Figure 2. A filter rod unit segment made of grapefruit peel granular material. The cellulose acetate filter rod unit section is wrapped with inner-wrapped molding paper, and the acetate fiber filter rod unit section wrapped with the inner-wrapped molding paper is connected with the grapefruit peel granular material unit filter rod section, and then packed into one body by the outer-wrapped molding paper to form a filter tip. The filter rod unit segment of the grapefruit peel granular material is formed by accumulating grapefruit peel particles of 20 to 40 meshes through the adhesion of an appropriate amount of modified starch. The cross-section of the filter rod unit section of grapefruit peel granular material is heart-shaped, and the cross-sectional area of the heart-shaped cross-section is 70% of the cross-sectional area of the filter rod. The filter rod unit segment of grapefruit peel granular material is set as the contact end between the filter tip and the shredded tobacco of the cigarette.
