Description

Technical Field

[0001] The present invention relates to the field of cigarette production equipment, and in particular to a cigarette flavoring and adding system. Background Art

[0002] Adding flavoring to cigarettes is a key step in controlling the taste of cigarettes. It can reduce irritation, make the smoke soft and delicate, improve the aftertaste, and make the smoke fuller. It has an important influence on improving and stabilizing the quality of cigarettes and establishing the style of cigarettes.

[0003] The working principle of cigarette flavoring and feeding is as follows: tobacco leaves are sent into the drum of the flavoring and feeding machine by a vibrating conveyor through upstream equipment, and circulating hot air is introduced into the drum. The drum is driven to rotate by a transmission device. Due to the axial inclination of the drum and the guiding effect of the material-push rod in the drum, the tobacco leaves can automatically flow toward the discharge port loosely and evenly. While rolling forward in the drum, the tobacco leaves are fully in contact with the flavors and spices sprayed from the dual-media nozzles to meet the process requirements of flavoring and feeding.

[0004] The cigarette wire production line needs to switch between multiple brands during production. Different brands of cigarettes are equipped with different flavors and fragrances. In order to avoid mixing brands, the flavoring and feeding system needs to be cleaned during brand change production, which is specifically divided into material tank cleaning, pipeline cleaning and nozzle cleaning. In the relevant technology, in the nozzle cleaning link, the operator first needs to open the drum door, hang the material receiving barrel at the nozzle, and then add water to the pipeline between the material tank and the nozzle to clean the residual flavors and fragrances in the nozzle, and then spray the pipeline to clean the residual water, and finally take out the material receiving barrel and close the drum door.

[0005] The above nozzle cleaning process takes a long time, and does not include the time required for reheating the hot air temperature after the drum door is opened, resulting in a long waiting time for changing cards. Nozzle cleaning requires operators to enter the drum. Since the inner wall of the drum is covered with rake nails and guide plates, once the cleaning personnel slip in the drum, they are easily injured, causing safety accidents. Utility Model Content

Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present disclosure; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0040] In the related art, the nozzle cleaning process takes a long time because: during cleaning, the largest proportion of time is spent on opening the drum door, hanging the receiving bucket, taking out the receiving bucket, and closing the drum door, which usually takes several minutes, much longer than the time required for cleaning and blowing the nozzle and its surrounding pipes.

[0041] For the above reasons, reference Figure 1 and Figure 2 Some embodiments of the present disclosure provide a cigarette flavoring and feeding system, including a first nozzle J1, a material tank T1, a material delivery pipeline G1, a connecting pipeline G2 and a first purge pipeline G3.

[0042] The first nozzle J1 has a first inlet, a second inlet and an outlet. The first inlet and the second inlet of the first nozzle J1 are respectively configured to pass flavors and spices and compressed gas required for flavoring tobacco leaves, so that the flavors and spices are sprayed out from the outlet of the first nozzle J1 in an atomized state under the action of compressed gas. The material tank T1 is configured to store flavors and spices. The inlet end of the feed pipeline G1 is connected to the material tank T1. The inlet end of the connecting pipeline G2 is selectively connected to the outlet end of the feed pipeline G1, and the outlet end is connected to the first inlet of the first nozzle J1. The first purge pipeline G3 is configured to pass compressed gas, and the first purge pipeline G3 is selectively connected to the inlet end of the connecting pipeline G2 to purge the flavors and spices in the connecting pipeline G2 and the first nozzle J1 by compressed gas.

[0043] Optionally, the cigarette flavoring and feeding system also includes an injection pipeline G9 and a feed valve V1 arranged on the injection pipeline G9, the feed valve V1 is configured to control whether the injection pipeline G9 injects flavors and fragrances into the material tank T1, and a discharge valve V2 is arranged at the outlet end of the material tank T1 to control whether the material tank T1 transports flavors and fragrances to the feed pipeline G1.

[0044] The working principle of the cigarette flavoring and feeding system provided by the embodiment of the present disclosure is as follows: before production, the required flavors and fragrances are injected into the material tank T1; then, the flavors and fragrances in the material tank T1 are transported to the feed pipeline G1 until the entire feed pipeline G1 is filled; during production, the inlet end of the connecting pipeline G2 is connected to the outlet end of the feed pipeline G1, and the flavors and fragrances enter the first nozzle J1 through the connecting pipeline G2, and under the action of the compressed gas, the flavors and fragrances are sprayed into the drum in an atomized state.

[0045] When it is necessary to clean the first nozzle J1, the inlet end of the connecting pipe G2 is disconnected from the outlet end of the feeding pipe G1 and connected to the inlet end of the first purge pipe G3. The compressed gas enters the connecting pipe G2 through the first purge pipe G3, and then enters the first inlet of the nozzle J1 through the connecting pipe G2. The flavors and fragrances filled in the connecting pipe G2 and the first nozzle J1 are sprayed into the drum and evenly mixed with the materials in the drum, thereby cleaning the first nozzle J1.

[0046] The nozzle cleaning process can be performed automatically without the need for manual operation steps such as opening the drum door, hanging the material receiving barrel, taking out the material receiving barrel, and closing the drum door, which can save the time occupied by the two steps, and will not cause the hot air temperature to drop, which can save the time of re-preheating the drum. Therefore, the cigarette flavoring and feeding system of the embodiment of the present disclosure can fully save the time required for self-cleaning, thereby saving the waiting time for brand change in cigarette production. The nozzle cleaning process does not require the operator to enter the drum, which can reduce safety hazards.

[0047] Since the inlet end of the connecting pipeline G2 and the outlet end of the feed pipeline G1 are selectively connected, and the flavors and fragrances filled in the connecting pipeline G2 and the first nozzle J1 can be blown clean by compressed gas, the above-mentioned nozzle cleaning process does not rely on adding water to the feed pipeline G1 for cleaning. Therefore, nozzle cleaning and other cleaning processes such as material tank cleaning and pipeline cleaning can be carried out independently at the same time, which is conducive to further saving the total time for cleaning the entire cigarette flavoring and feeding system.

[0048] In some embodiments, the cigarette flavoring and adding system has a first cleaning state. In the first cleaning state, the inlet end of the connecting pipeline G2 is disconnected from the outlet end of the conveying pipeline G1 and is connected to the first purge pipeline G3.

[0049] In the first cleaning state, the cigarette flavoring and adding system can perform nozzle cleaning.

[0050] In some embodiments, the cigarette flavoring and adding system includes a first purge control valve V12, which is disposed in the first purge pipeline G3 and is configured to control the on-off state of both ends of the first purge pipeline G3.

[0051] During production, the first purge control valve V12 controls the two ends of the first purge pipeline G3 to be disconnected to prevent the compressed gas from entering the first nozzle J1 from the first inlet of the first nozzle J1; during cleaning, the first purge control valve V12 controls the two ends of the first purge pipeline G3 to be connected to allow the compressed gas to pass through the first purge pipeline G3 and the connecting pipeline G2, and enter the first nozzle J1 from the first inlet of the first nozzle J1.

[0052] In some embodiments, the second inlet of the first nozzle J1 and the inlet end of the connecting pipe G2 are configured to be connected to the same gas source.

[0053] The above connection method can simplify the layout of the compressed gas pipeline and reduce the modification cost of the existing cigarette flavoring and feeding system. Optionally, the cigarette flavoring and feeding system includes an atomization pipeline G7 and a pressure control valve V9, the atomization pipeline G7 is arranged in parallel with the first purge pipeline G3, and the pressure control valve V9 is arranged on the atomization pipeline G7 to adjust the pressure of the compressed gas entering the first inlet of the first nozzle J1.

[0054] In some embodiments, the cigarette flavoring and feeding system includes multiple material tanks T1 and multiple material delivery pipelines G1 arranged corresponding to the multiple material tanks T1. Different material tanks T1 are configured to store different types of flavors and fragrances. The inlet end of the connecting pipeline G2 can be selectively connected to the outlet ends of the multiple material delivery pipelines G1.

[0055] In the above embodiment, during production, the inlet end of the connecting pipeline G2 is connected to the outlet end of one of the multiple material delivery pipelines G1 and disconnected from the outlet ends of the remaining material delivery pipelines G1. When it is necessary to change the brand, the inlet end of the connecting pipeline G2 is disconnected from the outlet end of the material delivery pipeline G1 and connected to the outlet end of another material delivery pipeline G1.

[0056] It can be seen that in the above embodiment, the process of cleaning one of the feed pipelines G1 and the corresponding material tank T1 does not affect the supply of the other feed pipeline G1 to the connecting pipeline G2 and the first nozzle J1. The cleaning process and the production process can be carried out simultaneously, which is beneficial to saving the waiting time for changing cards.

[0057] In some embodiments, the cigarette flavoring and adding system includes a second nozzle J2, a circulation pipeline G4 and a discharge pipeline G5. The second nozzle J2 is configured to spray water into the material tank T1. One end of the circulation pipeline G4 is selectively connected to the outlet end of the material delivery pipeline G1, and the other end is connected to the material tank T1. The inlet end of the discharge pipeline G5 is connected to the material delivery pipeline G1 and is configured to discharge the fluid in the material delivery pipeline G1.

[0058] Optionally, the cigarette flavoring and adding system further comprises a water supply pipeline G8 arranged upstream of the second nozzle J2 and a tank cleaning control valve V11 arranged on the water supply pipeline G8, and the tank cleaning control valve V11 is configured to control whether the water supply pipeline G8 sprays water into the tank T1 through the second nozzle J2.

[0059] The following further describes the process of tank cleaning and pipeline cleaning in some embodiments of the present disclosure.

[0060] After the production is finished and before cleaning, the outlet end of the feeding pipeline G1 is disconnected from the inlet end of the connecting pipeline G2 and connected to one end of the circulation pipeline G4. During cleaning, the material tank is cleaned first, water is added to the material tank T1 through the second nozzle J2 and the material tank T1 is cleaned. After the cleaning is completed, the cleaning water is discharged through the feeding pipeline G1 and the discharge pipeline G5; then the pipeline is cleaned, water is added to the material tank T1 through the second nozzle J2, and then the feeding pipeline G1 is flushed. After the cleaning water passes through the entire feeding pipeline G1, it enters the circulation pipeline G4, and returns to the material tank T1 through the circulation pipeline G4, and then the cleaning water is discharged through the feeding pipeline G1 and the discharge pipeline G5.

[0061] The outlet ends of different material conveying pipelines G1 and the inlet ends of the connecting pipeline G2 can be selectively connected by means of control valves or detachable joints.

[0062] In some embodiments, the cigarette flavoring and feeding system includes a flow control valve V8, which has a first valve port, a second valve port and a third valve port. The first valve port is connected to the outlet end of the feed pipeline G1, the second valve port is connected to the connecting pipeline G2, and the third valve port is connected to the circulation pipeline G4. The flow control valve V8 has a first working state and a second working state. In the first working state, the first valve port and the second valve port of the flow control valve V8 are connected, and the first valve port and the third valve port of the flow control valve V8 are disconnected. In the second working state, the first valve port and the second valve port of the flow control valve V8 are disconnected, and the first valve port and the third valve port of the flow control valve V8 are connected.

[0063] The flow control valve V8 can be a three-way valve. In the first working state, the outlet end of the feed pipeline G1 is connected to the connecting pipeline G2 and disconnected from the circulation pipeline G4; in the second working state, the outlet end of the feed pipeline G1 is disconnected from the connecting pipeline G2 and connected to the circulation pipeline G4.

[0064] For the case of multiple material delivery pipelines G1 and multiple material tanks T1, during production, the flow control valve V8 corresponding to one of the material delivery pipelines G1 is in the first working state, and the flow control valves V8 corresponding to the remaining material delivery pipelines G1 are in the second working state; when changing brands or cleaning, the flow control valve V8 in the first working state is switched to the second working state, and the other flow control valve V8 is switched from the second working state to the first working state.

[0065] In some embodiments, the cigarette flavoring and adding system further comprises a second purge pipeline G6, which is configured to be passed with compressed gas, and the inlet end of the second purge pipeline G6 is selectively connected to the circulation pipeline G4.

[0066] After cleaning the material tank T1 and the material delivery pipeline G1 with water, the second purge pipeline G6 is connected to the circulation pipeline G4, and the compressed gas enters the circulation pipeline G4 through the second purge pipeline G6, and then enters the material tank T1 and the material delivery pipeline G1 from the circulation pipeline G4. The compressed gas purges the residual moisture in the circulation pipeline G4, the material tank T1 and the material delivery pipeline G1 to the discharge pipeline G5 for discharge.

[0067] In some embodiments, the cigarette flavoring and adding system has a second cleaning state and a third cleaning state. In the second cleaning state, the inlet end of the feeding pipeline G1 is disconnected from the connecting pipeline G2 and connected to one end of the circulation pipeline G4, and the inlet end of the second purge pipeline G6 is disconnected from the circulation pipeline G4; in the third cleaning state, the inlet end of the feeding pipeline G1 is disconnected from the connecting pipeline G2 and connected to one end of the circulation pipeline G4, and the inlet end of the second purge pipeline G6 is connected to the circulation pipeline G4.

[0068] In the second cleaning state, the cigarette flavoring and feeding system can flush and clean the material tank and pipelines; in the third cleaning state, the cigarette flavoring and feeding system can purge the residual moisture in the material tank and pipelines.

[0069] In some embodiments, the second inlet of the first nozzle J1 , the inlet end of the connecting pipe G2 , and the inlet end of the second purge pipe G6 are configured to be connected to the same gas source.

The second purge pipeline G6 is provided with a second purge control valve V10, and the pressure control valve V9 is arranged on the atomization pipeline G7 to adjust the pressure of the compressed gas entering the first inlet of the first nozzle J1.

A sewage valve V4 is provided at the sewage end, and the sewage valve V4 is configured to control whether the discharge pipeline G5 discharges the cleaning water of the material tank T1 and the feed pipeline G1 through the sewage end.

[0073] After production and before cleaning, the inlet end of the discharge pipeline G5 is connected to the discharge end and disconnected from the sewage end to recover the remaining flavors and fragrances after production; after cleaning, the inlet end of the discharge pipeline G5 is connected to the sewage end and disconnected from the discharge end to discharge the cleaning water of the material tank T1 and the feed pipeline G1.

[0075] During production, the delivery pump P1 delivers the spices and flavors in the delivery pipeline G1 to the connecting pipeline G2; during cleaning, the delivery pump P1 delivers the cleaning water in the delivery pipeline G1 to the circulation pipeline G4, and then returns to the material tank T1 through the circulation pipeline G4, thereby facilitating the collection and discharge of the cleaning water.

The structures, connection relationships and functions of the components not listed can refer to the previous relevant descriptions.

[0080] In Table 1, opening any of the above-mentioned valves refers to making both ends of the valve in a connected state, and closing any of the above-mentioned valves refers to making both ends of the valve in a disconnected state.

[0081] Table 1 Cleaning process of cigarette flavoring and adding system

[0082]

[0083] As can be seen from Table 1, for the cigarette flavoring and feeding system of the above embodiment, the nozzle cleaning time is only a few seconds, which can significantly shorten the time required for nozzle cleaning compared to the cleaning method in the related art. Although the material tank cleaning and pipeline cleaning require a long time, since the cleaning process of one material tank T1 and the corresponding material delivery pipeline G1 and the feeding process of the other material delivery pipeline G1 can be carried out at the same time, there will be no additional waiting time for changing cards.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present disclosure rather than to limit it.
