Description

Paper bridge filter stick manufacturing device and paper bridge filter stick

Technical Field

The utility model relates to the technical field of cigarette filter sticks, in particular to a paper bridge filter stick manufacturing device and a paper bridge filter stick.

Background

The filter material of the conventional cigarette filter stick is a diacetate fiber bundle, and the filter material has good molding plasticity, stable filter effect and no obvious taste. Paper filter rods replace diacetate fiber tows with paper materials, and have the advantages of low cost (about one third of the tows) and easy degradation (90% degradation in 90 days). With these advantages, paper filter rods are increasingly gaining importance to the tobacco industry.

However, the paper filter rod has obvious defects relative to the acetate fiber filter rod, namely, the filtering effect (i.e. interception) is too high, the suction resistance (i.e. suction resistance) is too large and unstable, and the suction experience of cigarettes is greatly negatively influenced.

In order to solve the problem of high interception and high suction resistance of the paper filter stick, paper bridge filter sticks appear in the industry. The paper bridge filter stick uses filter element paper with high stiffness, so that larger pores are formed when the paper is filled in the filter stick. Like this, when flue gas passes through this kind of filter rod, most flue gas can directly pass through the filter rod and can not be held back, and inhale like this and hinder and hold back can reduce by a wide margin, when flue gas passes through moreover, can be by paper filter media lowering temperature to reach the purpose of cooling, this very is fit for the characteristic demand of novel heating incombustible cigarette. This makes the paper filter rod more advantageous in cooling than acetate fiber filter rods because the paper material has better water absorbency than the tow.

The existing paper bridge filter stick has the defects of relatively large pores of the paper filter material, relatively random irregular forming and quite irregular end surface. More importantly, although the resistance of the smoke is smaller when the smoke passes through the pores, the smoke resistance is sometimes relatively smaller and sometimes relatively larger due to irregular forming, and after the filter rod is cut, the filter rod reacts on the index, namely the fluctuation value of the suction resistance of the filter rod after the cutting is larger and the filter rod is unstable (Cov is more than 30%). Because of irregular shaping and unsightly appearance, paper bridge filter sticks are generally not placed on the proximal lip segment, and are only visible to the consumer and can be placed away from the proximal lip end and combined with other types of filter sticks.
