Description

Technical Field

[0001] The present invention relates to the technical field of cigarette machinery and equipment, and more specifically, to a flavoring device for heating a cigarette smoking matrix. Background Art

[0002] Orderly heated cigarettes are one of the main technical routes of new tobacco. Its processing technology is to make the smoking matrix into a continuous sheet base, cut it into a certain width, rewind it, and vacuum-seal it for packaging to prevent moisture changes. Commonly used smoking matrix processing technologies include new thick pulp thin sheets, papermaking thick pulp composite thin sheets, dry papermaking thin sheets, etc.; when producing ordered heated cigarettes, heated cigarettes are produced through processes such as unrolling, flattening, slitting, flavoring, bundling, forming, cigarette cutting, and filter rod overlapping.

[0003] At present, the multi-flavor of heated cigarettes has become an important means to shape the style of finished products and meet consumer demand, such as amber, blueberry, mint, cantaloupe, tangerine peel and other flavors. The proportion of flavoring for different flavors is generally between (1.0-6)%. The processing methods include cast-type flavoring and atomization flavoring. Since the flavoring is added during the rolling process, the vehicle speed is relatively high (3000 sticks / minute-5000 sticks / minute), and the running speed of the smoke matrix is ​​(45-75) meters / second. The applied flavors are difficult to be absorbed by the thin slices. The atomization flavoring method will form dot-like yellow spots on the cigarettes. The cast-type flavoring is random, and since the flavoring traces are concentrated in a certain position of the smoke matrix, the proportion of the fragrance liquid in a certain position reaches more than 50%, which is easy to form strip-like yellow spots. In order to solve the problem of yellow spot cigarettes, aluminum-coated cigarette paper is generally used for isolation, which effectively improves the problem of yellow spot cigarettes. However, it is found in the production process that when the proportion of flavoring is large, a certain proportion of cigarettes still have yellow spot cigarettes, the proportion is between 13-15%. In order to prevent the yellow spot cigarettes from flowing into the next process, the cigarettes are generally rolled and placed for a period of time, and then manually selected to solve the problem of yellow spot cigarettes, resulting in continuous production and high consumption.

[0004] Therefore, how to provide a flavoring device for heating the smoking matrix of cigarettes has become a technical problem that urgently needs to be solved in this field. Summary of the invention

[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0029] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0031] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0032] like Figure 1 to Figure 2 As shown, an embodiment of the present invention provides a flavoring device for heating a smoking substrate of a cigarette, comprising: a housing upper cover 1, a housing lower cover 2, a support assembly 3 and a flavoring assembly.

[0033] The upper shell cover 1 and the lower shell cover 2 are rotatably connected, and there are installation cavities inside the upper shell cover 1 and the lower shell cover 2. The upper shell cover 1 is provided with an opening 11 communicating with the installation cavity.

[0034] Specifically, the housing upper cover 1 is rotated to open the installation cavity, and the sheet can be placed into the installation cavity or guided out of the installation cavity.

[0035] The support assembly 3 is located in the installation cavity, and the support assembly 3 is used to provide support for the sheet.

[0036] The fragrance adding component is located above the opening 11, and is used to add fragrance to the sheet on the supporting component 3. Specifically, the fragrance adding component sprays fragrance into the installation cavity through the opening 11.

[0037] The negative pressure assembly 4 is arranged at the bottom of the lower cover 2 of the housing and is connected to the installation cavity. It should be noted that since the fragrance is atomized by compressed air, the fragrance diffused inside overflows the fragrancer, which is easy to cause fragrance loss and affect the production environment. The air in the installation cavity is extracted by the negative pressure assembly 4 to allow the fragrance to pass through the gaps between the thin sheet bundles.

[0038] During use, when the thin slices are conveyed to the fragrance adding device and pass through between the upper cover 1 and the lower cover 2 of the shell, the support component 3 provides support for the thin slices, and the fragrance adding component sprays fragrance into the installation cavity through the opening 11. At the same time, the negative pressure component 4 works to suck out the air in the installation cavity, so that the fragrance droplets pass through the gaps between the thin slice filament bundles, thereby intercepting the fragrance.

[0039] The present invention provides a mounting cavity inside the housing upper cover 1 and the housing lower cover 2 by rotationally connecting the housing upper cover 1 and the housing lower cover 2, and the housing upper cover 1 is provided with an opening 11 communicating with the mounting cavity, the support component 3 is located in the mounting cavity, the fragrance component is located above the opening 11, and the negative pressure component 4 is arranged at the bottom of the housing lower cover 2 and communicates with the mounting cavity. When in use, when the slice is conveyed to the fragrance adding device and passes between the housing upper cover 1 and the housing lower cover 2, the support component 3 provides support for the slice, and the fragrance adding component sprays fragrance into the mounting cavity through the opening 11. At the same time, the negative pressure component 4 works to suck out the air in the mounting cavity, so that the fragrance droplets pass through the gaps between the slice filament bundles, thereby intercepting the fragrance, ensuring the fragrance adding accuracy, reducing the fragrance loss, and effectively improving the yellow spot smoke problem, reducing the probability of unqualified products and production costs.

When the housing upper cover 1 and the housing lower cover 2 are buckled with each other, the inner side wall of the first supporting protrusion 31 and the inner side wall of the second supporting protrusion 32 are both in contact with the side wall of the limit block 35, thereby fixing the sheet in the installation cavity.
