Description
Technical Field
The invention relates to the field of cigarette filter stick preparation, in particular to a hollow bead blasting filter stick and a preparation device and method thereof.
Background
Along with the attention of consumers to health problems and the improvement of the demand on the personalized experience of cigarette products, the tobacco industry continuously responds to the demand upgrade of consumers and develops various smoking articles with the functions of reducing tar and harm. The heating cigarette is different from the traditional cigarette product in the cigarette heating mode, so that the cigarette can meet the sensory requirements of consumers on the cigarette product and provide healthier smoking experience.
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 a lip-end acetate fiber filtering section, and the aromatic substances are more easily volatilized and released, so that the aromatic substances have a good application prospect in perfuming the hollow filter stick used for the supporting 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 triacetin circulates throughout the system, resulting in a cumbersome change of the perfuming formulation and a need for 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, which is costly to retrofit. 2. After being remoistened 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 addition, 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 perfuming substance can not overflow sufficiently. 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 smoke to flow through, the smoke can preferentially pass through the hollow cavity, so that the flavoring effect of the flavoring substance which is infiltrated into the whole hollow filter stick on the smoke is not good, and the flavoring is hoped to be added in the hollow channel per se. 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.
The bead is a small liquid rubber bead embedded in the tobacco filter tip and wraps liquids with different types of flavors, so that a smoker can pinch and burst in the smoking process to enable the liquid in the bead to flow out, the taste of the cigarette is richer and more fragrant, and the smoker can obtain more comfortable experience. The prior art mainly adds the blasting beads into the solid filter stick, but can not combine the blasting bead filter stick with the hollow structure, because the hollow structure can not stably clamp the blasting beads, the problem becomes the difficult point of the tobacco filter stick industry at present.
In summary, how to prepare the hollow bead blasting filter stick and ensure that the hollow structure can stably clamp the blasting beads is a problem to be solved by people.
The present invention has been made to solve the above problems.

The fourth aspect of the present invention provides a method for preparing a hollow exploded bead filter rod according to the first aspect of the present invention, using the preparation apparatus according to the third aspect of the present invention, comprising the steps of:
A. filling the blasting beads 2 into the blasting bead storage bin N5;
B. starting the control system N3, and conveying the blasting beads 2 in the blasting bead storage bin N5 to the hollow chamber 12 of the rigid rod 11 through the blasting bead inlet 13 by using the pump N4;

Furthermore, when the explosion beads 2 are not arranged in one hollow channel 3, the rigid rod 11 corresponding to the hollow channel 3 is not required to be provided with a cavity chamber and a glue applying opening.
Compared with the prior art, the invention has the following beneficial effects:
1. the hollow cavity of the hollow filter stick is an airflow channel for the circulation of smoke, and the smoke can preferentially pass through the hollow cavity, so that the whole flavoring effect of the hollow filter stick on the smoke is not good.
2. The rigid rod with the hollow cavity, the bead blasting inlet and the bead blasting outlet is designed, the complex steps of additionally coating or spraying aroma-enhancing substances on the inner surface of the hollow cavity or additionally filling bead blasting in the hollow channel are omitted, the bead blasting is filled in the hollow channel while the hollow filter stick is bundled to form the hollow cavity directly, an aroma-enhancing process is not required to be specially arranged, and the steps are simple.
3. If the hollow filter stick is formed first, the bead blasting process is filled in the hollow channel of the hollow filter stick, and the problem is solved: if the bead size is smaller than the hollow channel size, although easy to fill, the hollow channel cannot stably hold the bead. If the size of the blasting bead is larger than that of the hollow channel in order to stably hold the blasting bead, the blasting bead is difficult to fill the formed hollow channel, and the blasting bead is easy to damage after being squeezed in the filling process. According to the invention, the hollow filter stick is directly bundled to form a hollow cavity, the blasting beads are filled in the hollow channel, the filter stick base material filament bundle firstly enters the bundling bell mouth, the bundled and gathered filament bundle passes through the rigid rod, the filament bundle advances forwards along with the filament bundle, the blasting bead outlet pushes half of the blasting beads at the foremost end to leak outside, the half of the blasting beads which leak forwards along with the filament bundle enter the hollow cavity of the filter stick after receiving friction force, and the self elasticity of the blasting beads is in interference fit with the hollow inner wall of the filter stick because the size of the blasting beads is larger than that of the hollow cavity of the filter stick. The hollow filter stick is directly bundled to form a hollow structure, meanwhile, the blasting beads are filled in the hollow channel, and the diameter of the blasting beads is ensured to be larger than that of the hollow channel, so that the blasting beads can be easily filled, and the hollow channel can be stably clamped.
4. When the spice formulas with different flavor characteristics are replaced, only the type of the popping beads in the hollow chamber needs to be replaced, and the device is not related to other parts of the device and is convenient to replace.
5. The flavoring of the hollow filter stick can be finished only by adding the rigid stick on the existing filter stick bundling equipment, and the equipment modification cost is low and the efficiency is high.
6. Compared with the perfuming method of adding soluble essence into a plasticizer, the perfume and essence of the invention has wide selection range, and only needs to be made into a bead to be filled into a cavity chamber of a rigid rod. Compared with the perfuming method for adding the granular perfume into the acetate fiber before bunching, the perfuming method disclosed by the invention overcomes the defect that the granular perfume is adhered to the whole forming channel after being subjected to moisture regaining by condensed water, so that the efficiency and the stability of equipment are influenced.
