Embodiment 1

[0030] Such as figure 1 , figure 2 The fine grooved filter rod shown is composed of forming paper 3 and grooved cellulose paper wrapped around the filter core 1. The length of the filter rod is 120 mm, and the circumference of the filter rod is 17.5 mm (the diameter of the filter rod 4 is about 5.57 mm. ), the grooved cellulose paper is fine grooved cellulose paper 2, the grammage is 65g / m2, and it contains 18 pairs of fine grooves consisting of convex grooves 7 and concave grooves 6; The tooth shape of the groove is trapezoidal tooth, arc-shaped tooth or rectangular tooth 8, and the pressure depth 5 of the fine branch groove is 0.45mm; the temperature of the groove roller used in the production and shaping stage of the fine branch groove is 100°C- 130°C; all or part of the thin branch grooves are continuous along the length of the filter rod.

[0031] When the tooth shape of the thin-branched groove is trapezoidal or rectangular, the bottom opening 12 of the convex groove...

Embodiment 2

[0033] Such as image 3 For the thin-grooved filter rod shown, the top width of the convex groove 7 is equal to the width of the bottom opening 12, the tooth shape of the convex groove 7 is a rectangular tooth, and the tooth shape of the concave groove 6 is a trapezoidal tooth .

Embodiment 3

[0035] Such as Figure 4 In the cross-section of the thin-branched groove composite filter rod shown, the two sides of the convex groove 7 are glued together to form a radial shape of fins 9, and the thickness of the fins 9 is two layers of cellulose paper. thickness of. The fiber material of the filter element 1 does not enter into the convex groove 7, and the filter element 1 maintains good roundness and stable filtering performance. After the fine-groove filter rod is cut, the short-cut filter rods of the ordinary fine-branch acetate fiber filter rod with the same circumference are connected end to end and spliced ​​together, and the same outer ring forming paper is wrapped to form a fine-groove composite filter rod. Great.

Abstract

The invention discloses a fine-count groove filter stick which is composed of a piece of forming paper, a piece of fine-count groove cellulosic paper and a filter element. The number of fine-count grooves ranges from 12 pairs to 22 pairs. Teeth of the fine-count grooves are trapezoid teeth or rectangular teeth. The pressing depth of the fine-count grooves ranges from 0.35 mm to 0.5 mm. All the fine-count grooves or some fine-count grooves cannot be continuous in the length direction. The fine-count grooves can be straight-grain grooves parallel to the center axis of the filter stick or sloping-grain grooves forming a certain angle with the center axis of the filter stick. The gram weight of the fine-count groove cellulosic paper ranges from 50 g / m<2> to 90 g / m<2> when the fine-count groove cellulosic paper does not press the grooves. According to the production and shaping stage of the fine-count grooves, the minimum temperature of adopted groove rollers is 100 DEG C, and the maximum temperature of the adopted groove rollers is 130 DEG C. When the teeth of the fine-count grooves are the trapezoid teeth or the rectangular teeth, the width of bottom openings of the convex grooves is smaller than that of the bottom edges of the concave grooves. A fine-count groove composite filter stick can be formed by splitting and splicing the thin-count groove filter sticks. The fine-count groove filter stick has the advantages of being low in suction resistance, stable in pressure drop, lower in cost compared with a common groove filter stick, good in appearance quality and the like.

Description

technical field [0001] The invention relates to a raw material groove filter rod for manufacturing cigarette filter tips and a composite filter rod thereof. Background technique [0002] The existing grooved filter rods are constructed from filter elements, grooved cellulose paper and molding paper. The length of ordinary grooved filter rods is 120-144mm, and the circumference of the cross section is 23-25mm. Similar convex and concave grooves are formed alternately. The tooth shape (cross-sectional shape) of the groove is generally trapezoidal or semicircular arc-shaped. The number of grooves is generally 20-24, and the groove depth is generally 0.55. -0.8mm. The diameter of the filter rod is relatively thick, and the products of various enterprises have little difference and lack of characteristics. [0003] Existing slim filter rods are constructed of filter elements and molded paper, have low hardness, high suction resistance and are not stable enough to meet the requi...
