Description

TECHNICAL FIELD

[0001] The utility model relates to cigarette filter stick technical field especially, relate to a paper bridge filter stick manufacturing installation and paper bridge filter stick. BACKGROUND

[0002] The filter material of the conventional filter stick is cellulose acetate tow, the material has good formability and stability, and has no obvious odor. The paper filter stick uses paper material instead of cellulose acetate tow, and has the advantages of low cost (about one third of the cost of the tow) and easy degradation (90% degradation in 90 days). With these advantages, the paper filter stick is increasingly valued by the tobacco industry.

[0003] However, the paper filter stick has obvious disadvantages compared with the cellulose acetate filter stick, that is, the filtration effect (i.e. interception) is too high, the suction resistance (i.e. draw resistance) is too large and unstable, and has a great negative impact on the smoking experience of the cigarette.

[0004] In order to solve the problem of high interception and large suction resistance of the paper filter stick, the paper bridge filter stick appears in the industry. The paper bridge filter stick uses high-stiffness filter core paper, so that the paper forms large pores when filling in the filter stick. In this way, most of the smoke can pass through the filter stick directly without being intercepted when the smoke passes through such filter stick, so that the suction resistance and interception are greatly reduced, and the temperature of the smoke is reduced when passing through the paper filter material, thereby achieving the purpose of temperature reduction, which is very suitable for the characteristics of the new type of heat-not-burn cigarette. Because the water absorption of the paper material is better than that of the tow, the paper filter stick has more advantages than the cellulose acetate filter stick in temperature reduction.

[0005] The existing paper bridge filter stick has large pores in the paper filter material, and the forming is irregular and random, so the end surface looks very uneven. More importantly, although the resistance of the smoke is small when passing through the pores, due to the irregular forming, the resistance of the smoke is relatively small sometimes and relatively large sometimes, and the filter stick strip is cut, and the index is reflected on the cut filter stick, that is, the suction resistance fluctuation value of the cut filter stick is large and unstable (Cov is greater than 30%). Because of the irregular forming and poor appearance, the paper bridge filter stick cannot be placed in the near-lip section and seen by the consumer, and can only be placed in the position away from the near-lip end and compounded with other types of filter stick.

[0054] Based on the above-described paper bridge filter rod manufacturing apparatus, this utility model also proposes a paper bridge filter rod, which is manufactured using the above-described paper bridge filter rod manufacturing apparatus.

[0055] The paper bridge filter rod manufacturing device provided by this utility model uses a first mold and a second mold, which have protrusions and grooves respectively, to extrude paper material 3, so that the paper material 3 is regularly pre-bent in the gap formed between the protrusions and grooves. The paper bridge filter rod manufactured by subsequent processes has regular holes, and the appearance quality and suction resistance uniformity of the filter rod can be greatly improved.

[0056] The positive technical effects of the paper bridge filter rod manufacturing apparatus in the above embodiments also apply to paper bridge filter rods, and will not be repeated here.

[0057] The following is in conjunction with the appendix Figs. 1 to 3 The structure and working process of one embodiment of the paper bridge filter rod manufacturing device provided by this utility model will be described:

[0058] like Fig. 1 As shown, the paper bridge filter rod manufacturing device includes a first mold 1 and a second mold 2, which are basically the same in shape and size. Both the first mold 1 and the second mold 2 are cubes or cuboids. The first mold 1 and the second mold 2 are fastened together and connected by bolts.

[0059] The first mold 1 has a first surface 10, and the second mold 2 has a second surface 20. The first surface 10 and the second surface 20 are disposed opposite to each other, and there is a gap between the first surface 10 and the second surface 20.

[0060] like Fig. 2 As shown, a trapezoidal groove is provided on the first surface 10 of the first mold 1, and multiple bosses 11 are provided in the trapezoidal groove. The bosses 11 include a first boss 111 located in the middle and multiple second bosses 112 and third bosses 113 located on both sides of the first boss 111.

[0061] The first mold 1 has a first side 12 and a second side 13 arranged opposite to and parallel to each other, as well as a fifth side and a sixth side arranged opposite to and parallel to each other. The fifth and sixth sides are both located between the first side 12 and the second side 13. A first boss 111 is perpendicular to the first side 12 and the second side 13, and parallel to the fifth and sixth sides. Along a direction perpendicular to the first side 12 and the second side 13, the second boss 112 and the third boss 113 gradually approach the first boss 111. Looking from the first side 12 to the second side 13, multiple bosses 11 gradually converge towards the center. Looking from the second side 13 to the first side 12, multiple bosses 11 are radially distributed.

[0062] The structure of the second mold 2 is similar to that of the first mold 1. The second surface 20 of the second mold 2 is provided with a trapezoidal groove, and multiple protrusions are also provided in the trapezoidal groove. A groove 21 is formed between two adjacent protrusions. The position of the groove 21 corresponds to the position of the boss 11 on the first mold 1, so that the boss 11 can be inserted into the groove 21. The number and inclination direction of the groove 21 match the number and inclination direction of the boss 11.

[0063] like Fig. 3 As shown, each boss 11 is inserted into the corresponding groove 21. The boss 11 and the groove 21 are not in direct contact. There are gaps between each outer surface of the boss 11 and the bottom surface and wall surface of the groove 21, forming a passage path for the paper material 3.

[0065] In the embodiment of the paper bridge filter rod manufacturing device provided by this utility model, the first mold 1 and the second mold 2 are connected to each other, forming a sawtooth space inside. The paper material 3 enters the space from the inlet where the first side 12 is located, is compressed to form an orderly wave shape and gradually shrinks, the spacing of the waves becomes denser, the paper material 3 is combed, and pre-bending is achieved before forming. In this way, when it is subsequently formed into a filter rod, the paper material 3 will be distributed in a pre-bent shape inside the filter rod, achieving the purpose of controllable curling, effectively improving the appearance of the paper bridge filter rod and improving the suction resistance fluctuation of the filter rod.

[0066] By changing the number, shape, and orientation of the bosses and grooves, the number and shape of the channels in the formed paper bridge filter rod can be adjusted, thereby adjusting the appearance and suction resistance of the paper bridge filter rod. For example, three-cavity paper bridge filter rods, six-cavity paper bridge filter rods, petal-shaped paper bridge filter rods, etc. can be formed as needed.

[0067] The paper bridge filter rod manufacturing device can regularly pre-bend and form the paper material with high toughness and elasticity, so that the paper material is more easily to enter the subsequent cigarette gun forming, and the stable production of the regularly arranged paper bridge filter rod is realized.

[0068] The above description of various embodiments tends to emphasize the differences between various embodiments, and the same or similar parts can be mutually referred to, and for the sake of brevity, will not be repeated here.
