Description

Plugging device

Technical Field

The utility model relates to a technical field, in particular to plugging device that granule type cigarette was supported in low temperature incombustible.

Background

In recent years, with the remarkable improvement of health consciousness and environmental consciousness of consumers and the gradual deepening of scientific and technological research, a novel tobacco industry is rapidly emerging. By "new tobacco" is meant tobacco regenerants obtained by reprocessing tobacco plants, such as making tobacco sheets by paper making, making tobacco particles by pelleting, and the like. The tobacco regenerated material has special physical and chemical properties, so that the use method and the application conditions of different tobacco regenerated materials can be different.

It is well known that smoking of conventional cigarettes involves burning tobacco at high temperatures above 700 ℃ using open flame. Compared with the combustion and smoking of the traditional cigarette, the tobacco regeneration material is heated below 400 ℃ by electric heating, and the tobacco regeneration material is called as low-temperature non-combustible cigarette due to the low heating temperature and no open fire combustion. The contents for low-temperature non-combustible smoke mainly adopt novel tobacco, wherein, the attempt of using tobacco particles can be realized, and low-temperature non-combustible smoke products taking the tobacco particles as the main contents are continuously researched, developed and improved and are continuously accepted by the market.

However, the tobacco particles are in a loose and disordered state due to the special particle shape, so in the process of preparing a low-temperature non-combustion cigarette product, in order to enable the tobacco particles to be in an ideal state in the cigarette and keep the aroma substances of the tobacco particles not volatilized, a blocking device is often needed to be used for packaging the tobacco particles.

A conventional plugging device is a cartridge plug, that is, a cartridge or a segment of tobacco particles is made by plugging tobacco particles, for example, see application No. 201811487278.0 entitled "a tobacco particle type heating non-combustible tobacco product and a method for making the same", in which a base rod, a composite tip rod and a hollow pipe cigarette are first prepared, and then the tobacco particles are encapsulated, wherein the tobacco particles are filled between a front end plugging structure and a tail end plugging structure, the front end plugging structure uses an aluminum foil lining paper as a material, and the tail end plugging structure uses an aluminum foil as a material. In this patent, the paper air tube is a part of packaging shell body to directly pack tobacco particles, second cooling section and fibre filter stick, increase extra multilayer packaging material on this is exactly multilayer structure's paper air tube's basis, increased the wall thickness of cigarette, not only can influence the heat dissipation cooling effect of incombustible tobacco products, but also because do not burn tobacco products self volume size limit, reduce the effective utilization space of tobacco particles, and then influenced the final result of use of goods. In addition, in order to block the tobacco particles, the tobacco particle blocking device adopts a two-section blocking structure, so that the production process is complicated, the production efficiency is low, and the production cost is high.

Because the low-temperature non-combustible cigarettes need to be matched with a heating smoking set for use, most of the existing smoking sets are insertion type electric heating smoking sets, and therefore, the end face plugging devices of the cigarettes are all of a structure which is easy to puncture. In the blocking technology of particle tobacco products, the heat sealing technology of film covering materials is widely adopted at present. In the heat sealing technique of the film-covered material, a special processing technique is required in order to improve the air permeability of the film-covered material. For example, patent application No. 201811488351.6 discloses a novel non-rolled tobacco product containing tobacco particle material, which is made by attaching a graphene film to a fine glass fiber cotton, and uses a gas-permeable sheet material to seal the end of a paper hollow tube, and it is known from the disclosure of the patent document that the gas-permeable sheet material is made of a special material and processed by a special process to improve the gas permeability, thereby causing problems of complicated manufacturing process, long manufacturing period, great difficulty, and high cost of the manufactured product.

In addition, patent application No. CN201811484718.7 discloses a method for preparing an empty-tube filled type heating non-combustible smoking article with a sealing film and its application. The circular hollow pipe is made of materials with enough hardness to wrap the filler and support the filler without deformation, such as a paper pipe, an aluminum foil paper pipe, a ceramic pipe and the like; the sealing film is made of materials which are easy to be punctured by a heating sheet or a needle, such as perforated aluminum foil, high-air-permeability paper, coated paper or a high-temperature-resistant plastic film. For the circular hollow tube, a one-step rolling method of a formed paper sheet may be used, and a spiral method of a multi-layer paper sheet may be used, in which the circular hollow tube is made of a single material in a simple structure. This patent discloses that the sealing film may be made of perforated aluminum foil, high permeability paper, coated paper or high temperature resistant plastic film, and it is clear that this patent focuses only on the permeability of the sealing film. The inventor carefully researches and discovers that due to the application specificity of the packaging film of the tobacco regenerated substance, taking high-air-permeability paper as an example, the influence of the packaging film on the tobacco regenerated substance is not only a parameter index of air permeability, but also a plurality of parameter indexes such as paper material, strength, thickness, layer density, moisture regain and the like, and the difference of the parameter indexes is often determined to have different physical properties in terms of the high-air-permeability paper, so that the actual application effect of the high-air-permeability paper is greatly influenced.

In view of the above problems, the inventors of the present application found through a large number of experimental studies that: on one hand, the cigarette tube shell structure adopted in the existing plugging technology of the particle tobacco product can cause the wall of the cigarette tube shell to be too thick, so that the heat dissipation and cooling effects of the non-combustible tobacco product are influenced, the effective utilization space of tobacco particles can be reduced, and the material waste can be caused by the excessively thick wall of the branch pipe of the cigarette; on the other hand, the heat sealing technology of the film covering material widely adopted in the blocking technology of the granular tobacco products at present has the problems that technicians only pay attention to the air permeability of the blocking film covering, and the problems of smoking, deterioration and the like of tobacco granules can be caused due to the overhigh heat sealing temperature caused by the sealing performance of the film covering material, the using effect of the granular tobacco products is influenced, and a series of problems of high manufacturing cost, complex manufacturing process, great environmental pollution and the like can be caused; furthermore, synthetic fibers are adopted as the film coating materials widely adopted in the blocking technology of the granular tobacco products at present, non-edible glue is adopted as the bonding glue, and the materials can generate unpleasant chemical smell when being heated during the smoking process of users, so that the smoking feeling of the users is seriously influenced, even the health is seriously influenced.

In view of the above, the inventors of the present application have made extensive experimental studies, starting from technical improvements of the cigarette case structure and the blocking layer of the cigarette branch pipe, in order to improve the blocking technique of the particulate tobacco product from the aspects of increasing the effective utilization space of the cigarette branch pipe, improving the air permeability, reliability, simplicity of the manufacturing process, economical efficiency of the manufacturing cost, environmental friendliness, and the like, thereby improving the use effect of the particulate tobacco product.
