Description

Rigid rod for preparing hollow filter stick with functional strip on inner wall and filter stick preparation device

Technical Field

The utility model relates to a cigarette filter rod preparation field, concretely relates to rigidity stick and filter rod preparation facilities for preparing the cavity filter rod that the inner wall has the function strip.

Background

The existing aerosol generating product comprises a smoking section, a supporting section, a cooling section and a filtering section, wherein the supporting section, the cooling section and the filtering section can all use tow-shaped filter sticks, usually acetate tow filter sticks (acetate fibers are hereinafter referred to as acetate fibers for short), and can filter harmful ingredients in smoke. The solid filter stick has the characteristic of high interception rate, the interception rate of smoke needs to be reduced in the design of heating cigarettes, and a better method in the industry is to make the filter stick into a hollow filter stick.

At present, the production of hollow filter sticks basically adopts the mode that a rigid rod is additionally arranged at the rear end of a horn mouth of a conventional filter stick forming machine for converging, so that a hollow structure is formed at the position occupied by the rigid rod after acetate fiber tows are converged.

With the continuous upgrading of cigarette flavoring technology, each section of the cigarette gradually has flavoring requirements, and particularly for the novel tobacco product heating cigarette, the supporting section is usually an acetate fiber hollow filter stick. The section is close to a heat source, the smoke temperature is higher than that of the lip-end acetate fiber filter section, and the section is more suitable for volatilization and release of flavoring substances, so that the section has a good application prospect in flavoring the hollow filter stick for the support section.

As for the existing hollow filter stick processing technology, the available flavoring modes are few, and the existing hollow filter stick processing technology mainly comprises the following steps: 1. adding soluble essence into a plasticizer to perfume; 2. adding granular perfume into acetate fiber before bundling and gathering; 3. directly soaking the molded hollow filter stick in an aroma-enhancing substance to adsorb the aroma-enhancing substance; 4. and additionally coating or spraying an aroma-enhancing substance on the inner surface of the hollow cavity of the molded hollow filter stick. The first of the above methods has the disadvantages that: 1. only the flavor which is compatible with the triacetin can be selected, and the selection range of the essence flavor is narrow. 2. The perfumed glyceryl triacetate will circulate throughout the system, causing a troublesome change of the perfuming formulation and requiring thorough cleaning of the entire plasticizer application system. 3. The flavoring substance and the acetate fiber are integrated, namely the flavoring substance is dispersed in the filter stick main body, and when smoke passes through the filter stick main body, the smoke preferentially passes through the hollow channel with small suction resistance, so that the overflow of the flavoring substance is possibly insufficient. The disadvantages of the second method are: 1. a separate set of particulate flavor application system is required and the cost of retrofitting is high. 2. After being dampened by condensed water, the granular spice can be adhered to the whole forming channel, and the efficiency and the stability of the equipment are seriously influenced. 3. In the same way, the perfuming substance and the acetate fiber are integrated, and smoke preferentially passes through the hollow channel with small suction resistance when passing through the hollow channel, so that the overflow of the perfuming substance is possibly insufficient. The third method also has the problem that the flavoring substance is dispersed in the filter stick main body, and because the hollow cavity of the hollow filter stick is an airflow channel for the circulation of smoke, the smoke can preferentially pass through the hollow cavity, so that the flavoring effect of the flavoring substance for the smoke after the hollow filter stick is soaked integrally is not good, and the flavoring in the hollow channel is basically expected. Aiming at specially flavoring the hollow channel of the hollow filter stick, the fourth method for independently coating or spraying the flavoring substances has complicated steps and increases the cost.

In summary, it is a problem to be solved how to more simply arrange the fragrance-increasing layer on the inner surface of the hollow channel.

In order to solve the above problems, the utility model is provided.
