Description

Technical Field

[0001] The invention relates to the technical field of heated cigarettes, and in particular to a flavoring device and a cigarette core base rod production line. Background Art

[0002] As a new type of tobacco product, heated cigarettes are popular because of their sensory experience similar to traditional cigarettes. Flavoring technology can improve the aroma quality of cigarettes on the one hand, and give cigarettes different aroma styles on the other hand. Flavoring of heated cigarettes is generally achieved by online flavoring of the cigarette core slices during the preparation of the cigarette core rod. Its flavoring method is quite different from that of traditional cigarettes.

[0003] Regarding the flavoring of heated cigarette flakes, a mature system for widespread use has not yet been formed in the domestic tobacco industry, but related research has also been reported, such as the use of traditional glycerol ester spraying system flavoring, injection-type online base rod flavoring and nozzle atomization flavoring. These flavoring methods can achieve the flavoring of heated cigarette flakes to a certain extent, but there are also many shortcomings. In the process of flake flavoring, due to the fluctuation of quality between the flake shreds, different amounts of flavor spraying are required, but the above-mentioned flavoring equipment cannot adjust the amount of flavor applied in real time according to the quality of the flakes, which ultimately leads to a mismatch between the amount of flavor applied and the quality of the flakes, and the sensory quality of the product is highly volatile. Summary of the invention

[0004] The purpose of the present invention is to provide a flavoring device and a cigarette core base rod production line to solve the problem that the flavoring amount cannot be accurately measured according to the weight of the slices in the prior art, and the sensory quality of the product fluctuates greatly.

[0005] To achieve this object, the present invention adopts the following technical scheme: the present invention provides a fragrance adding device, including a thin film unwinding component, a nozzle, a conveying component and a storage barrel, the conveying roller receives the thin film transmitted from the thin film roll, the storage barrel stores the essence, the nozzle is connected to the storage barrel, the conveying component conveys the essence to the nozzle, the nozzle can spray the essence onto the thin film wire, the conveying roller conveys the thin film wire to the bottom of the nozzle, the conveying component includes a screw pump, and the screw pump can change the amount of the essence conveyed.

The control system is electrically connected to the weighing component and the screw pump respectively. When the weight values ​​of two adjacent groups in a unit time show an increasing trend, the control system controls the screw pump to increase the amount of flavor delivery. When the weight values ​​of two adjacent groups in a unit time show a decreasing trend, the control system controls the screw pump to reduce the amount of flavor delivery.

[0007] The fragrance adding device further includes a pneumatic triplet, which is connected to the outside world to absorb outside air to form positive pressure air. The pneumatic triplet is also connected to the storage barrel and the nozzle respectively. The positive pressure air can provide delivery pressure for the storage barrel, and the positive pressure air can also provide atomization pressure for the nozzle. The delivery component also includes a flow sensor, which is installed between the screw pump and the nozzle. The flow sensor can monitor the spraying amount of the fragrance;

[0008] The sheet unwinding component includes an air inflation shaft, a first support rod, a rotating support rod and a fixed support rod. An inner ring is arranged inside the sheet roll, and an air inflation shaft is passed through the inner ring. The air inflation shaft drives the sheet on the inner ring to rotate. One end of the air inflation shaft is connected by the first support rod, and the other end is detachably connected by the rotating support rod. The rotating support rod is rotatably connected to the fixed support rod.

[0009] Preferably, the storage barrel wall is provided with a heating element, which can increase the temperature of the essence.

[0015] Beneficial effect: By continuously measuring the weight change value in two adjacent unit times, if the weight value shows an upward trend, it means that the weight of the thin wire delivered to the bottom of the nozzle has increased, and the amount of flavor sprayed needs to be increased. Similarly, when the weight value decreases, the amount of flavor sprayed should be reduced so that the amount of flavor sprayed can change according to the mass change of the thin wire.

[0024] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0025] The existing tobacco core base rod production line is directly connected to the storage barrel through a nozzle to directly spray the flavor, but the above structure cannot spray corresponding weights of flavors for thin sheets of filaments of different weights, resulting in low consistency in the flavor concentration of tobacco core base rods produced by the existing technology. The sensory fluctuations of customers when using heated cigarettes are large, which affects the final product quality of the heated cigarettes.

[0026] In order to solve the above problems, Figure 1 to Figure 2 As shown, the present invention provides a flavoring device, including a thin film unwinding component 16, a nozzle 2, a conveying component and a storage barrel 3, wherein essence 4 is stored in the storage barrel 3, the nozzle 2 is connected to the storage barrel 3, the conveying component conveys the essence 4 into the nozzle 2, the nozzle 2 can spray the essence 4 from the bottom to the outside, the conveying roller 1 can convey the thin film filament 17 to the bottom of the nozzle 2, and the conveying component includes a screw pump 5, which can change the conveying amount of the essence 4.

[0027] A weighing component 6 is installed at the lower end of the sheet unwinding component 16 or the sheet roll 10. The present invention installs the weighing component 6 on the support rod on the lower side of the sheet roll 10. The weighing component 6 can measure the weight change value on the sheet roll 10 between two adjacent unit times. The control system is electrically connected to the weighing component 6 and the screw pump 5 respectively. When the average value increases, the control system controls the screw pump 5 to increase the delivery amount of the flavor 4. When the average value decreases, the delivery amount of the flavor 4 is reduced.

[0028] The screw pump 5 installed between the storage barrel 3 and the nozzle 2 can change the delivery amount of the flavor 4. The screw pump 5 is a prior art, and its technical principle is not described here. By setting the working program in the control system, setting:

[0029]

[0030]

[0031] Through the real-time adjustment of the control system, real-time adaptive adjustment can be made for thin sheets 17 of different weights, so that the flavor 4 sprayed on the thin sheets 17 is more stable and uniform, and the weight of the flavor 4 is proportional to the weight of the thin sheets 17, so that the final tobacco core base rod has a higher consistency in flavor.

[0032] The barrel wall of the storage barrel 3 of the present invention is provided with a heating element, which can increase the temperature of the essence 4 and ensure the molecular activity of the essence 4 so that it can be diffused onto the thin sheet 17 more stably and evenly.

[0033] By arranging a stirring arm 7 in the storage barrel 3, the stirring arm 7 rotates and is immersed in the flavor 4, the flavor 4 that is easy to be stratified in a static state is always in a uniform state under the rotation of the stirring arm 7, so that when it is sprayed onto the thin sheet 17, the diffusion state is more uniform. At the same time, after the flavor 4 of the present invention is sprayed through the nozzle 2, the excess flavor 4 is directly diffused to the outside and will not be recovered into the storage barrel 3, so that the flavor 4 stored in the storage barrel 3 can be guaranteed to have higher consistency and concentration, so that the state of spraying it onto the thin sheet 17 is more uniform.

[0034] The nozzles 2 include at least two groups, and the nozzles 2 are in the same horizontal plane and fan-shaped, so that the spraying surface 20 of the nozzle 2 can be elliptical, and the edges of the spraying surface 20 overlap each other, wherein the overlapping area 18 should be as small as possible to avoid repeated spraying of the flavor 4. At the same time, there is a blank space between the spraying area of ​​the thin silk 17 and the edge of the thin silk 17 of the flavor 4, and the blank area 19 is minimized as much as possible to avoid repeated spraying.

[0035] It should be noted that there is no special requirement for the number of nozzles 2 and it can be freely set. Generally, the number of nozzles 2 is 1-10 and they are at the same height as the sheet to ensure the consistency of the sheet filaments 17 after being sprayed with the essence 4.

[0036] The flavor 4 sprayed outward from the nozzle 2 forms a spray angle β, β is set between 20° and 80°, the distance between the nozzle 2 and the thin wire 17 is 10mm-100mm, and the spray angle is set within the above angle through multiple tests and measurements. At the same time, when the distance between the nozzle 2 and the thin wire 17 is controlled within the above range, the flavor 4 is spread most evenly, so that the final tobacco core base rod has better consistency, and because the spray angle and the distance between the nozzle 2 and the thin wire 17 can be adjusted to any height, the flavoring device is more applicable and can be adapted to different tobacco core base rod production lines.

[0037] At least two groups of conveying rollers 1 are arranged at the bottom of the nozzle 2. By arranging conveying rollers 1 on both sides below the nozzle 2, the above-mentioned thin film wire 17 can be smoother during transmission, so that it can contact with the sprayed flavor 4 more evenly, and finally the flavor 4 on the thin film wire 17 can be more evenly distributed.

[0038] The fragrance adding device also includes a pneumatic triplet 8, which is connected to the outside world to absorb outside air to form positive pressure air. The pneumatic triplet 8 is also connected to the storage barrel 3 and the nozzle 2 respectively. The positive pressure air can provide a delivery pressure for the storage barrel 3. The above delivery pressure can make the essence 4 in the storage barrel 3 be sent to the outside at a uniform speed. The positive pressure air can also provide atomization pressure for the nozzle 2, so that the atomization effect of the nozzle 2 is more uniform. The atomization pressure of the present invention is 0.01-0.5Mpa, which can ensure that the essence 4 can be sprayed in the designated area and will not be wasted.

[0039] The conveying component of the present invention also includes a flow sensor 9, which is installed between the screw pump 5 and the nozzle 2. The flow sensor 9 can monitor the spraying amount of the flavor 4. The amount of flavor 4 passing through the screw pump 5 can be monitored in real time through the above sensor. Real-time monitoring can be performed, which makes it convenient for staff to observe whether the fragrance adding device is in a normal working state.

[0040] A cigarette core base rod production line, such as Figure 3 As shown, it includes the above-mentioned flavoring device, wherein the flavoring device is arranged between the output roller and the cigarette tongue 12, and also includes a thin film roll 10, the thin film roll 10 releases thin films, the thin film cutting condition 11 cuts the thin films into thin film strands 17, the thin film strands 17 are transported to the flavoring device through the conveying roller 21, the cigarette tongue 12 gathers the thin film strands 17 of the flavoring device and enters the cigarette gun 13 to be processed into strips, at this time the shaping paper supply part 14 also conveys the shaping paper to the production line, after the shaping paper is wrapped, the continuous thin films are cut into cigarette core base rods of predetermined length under the action of the cutting head 15, the length of the cigarette core base rod is 50mm-200mm, and the diameter is φ4.5mm-φ9mm.

[0041] like Figure 4As shown, the sheet unwinding member 16 includes an air inflation shaft 22, a first support rod 23, a rotating support rod 24 and a fixed support rod 25. The sheet roll 10 is fixed on the air inflation shaft 22 under the support of the sheet inner ring 27, and rotates along its own axis at a set speed following the air inflation shaft 22. The air inflation shaft 22 is supported by the first support rod 23, the rotating support rod 24 and the fixed support rod 25. The first support rod 23 and the fixed support rod 25 are fixedly connected to the weighing member 6, and the weight change of the sheet roll 10 is monitored in real time, and the weight change value within two unit times is transmitted to the control system through the data transmission line 28. The fixed support rod 25 is connected to the rotating support rod 24 through a rotating point 26. The rotating support rod 24 can rotate relative to the fixed support rod 25. When the film roll 10 needs to be replaced, the rotating support rod 24 is first rotated to take out the remaining film roll 10 from the previous working process, and then the new film roll 10 is installed, and then the rotating support rod 24 is rotated again. The rotating support rod 24 is temporarily fixedly connected to the fixed support rod 25 to support the film roll 10.
