[0091] In another typical embodiment of the present application, a method for automatically and flexibly manufacturing tobacco cores of cigars is provided, which uses the above production line and specifically comprises the following steps:

[0092] S1: automatic feeding.

[0093] The tobacco raw material is loaded into the feeding trolley, and the feeding trolley is placed into the first box-turning feeder 1, the tobacco raw material is automatically fed through the operation of the first box-turning feeder 1, the lifting belt in the box-turning feeder intermittently works according to the control program thereof, and uniform feeding to the production line is realized.

[0094] S2: leaf moistening and feeding.

[0095] After the automatic feeding of the tobacco raw material, the first box-turning feeder 1 sends the tobacco raw material to the leaf moistening and feeding machine 5 through the vibration conveyors 2 and 4, and the belt scale 3 between the vibration conveyors 2 and 4 uniformly sends the tobacco raw material into the leaf moistening and feeding machine 5 at a certain flow rate.

[0096] The feeding drum of the leaf moistening and feeding machine 5 rotates, has a certain inclination angle, and the tobacco raw material rotates in the feeding drum along the direction of the inclination angle and is discharged from the feeding drum.

[0097] In the process of rolling of the tobacco raw material in the feeding drum, steam is used to inject water mist into the feeding drum, and the water mist is sprayed together with steam on the surface of the tobacco leaf to realize temperature and humidity increase of the tobacco leaf; and air pressure is used to inject the base material into the feeding drum, and the base material is atomized and uniformly sprayed on the surface of the tobacco leaf to realize uniform feeding.

[0098] S3: threshing and air separation.

[0099] The tobacco leaf after temperature and humidity increase and feeding is sent into the threshing and air separation system through the vibration conveyors 6 and 7 to be threshed and air separated.

[0100] In the leaf beater, tobacco leaves are separated from tobacco stems under the action of mechanical tearing. In the air classifier, tobacco leaves meeting the size requirements are taken out by air classification and then sent to the next production link by the conveying belt. Tobacco leaves and stems that are not taken out by air classification continue to circulate and be beaten until they meet the size requirements and are taken out by air classification.

[0101] In this step, tobacco leaves are beaten and classified in two stages. After the first stage of beating, the tobacco leaves are classified twice (i.e., first-stage classification and second-stage classification). After the second stage of beating, the tobacco leaves are classified once (i.e., second-stage classification). The second-stage classification of the first stage of beating and the first-stage classification of the second stage of beating share one air classifier. The process of second-stage classification and second-stage beating is repeated. The tobacco stems after the second-stage classification are recycled by the stem falling device. The tobacco leaves after the circulation of beating and classification are taken out by air classification.

[0102] Specifically, first, the tobacco leaves enter the first-stage beater 8 to be beaten in the first stage. Then, the material after beating enters the first-stage air classifier 9 to be classified in the first stage. The leaves meeting the size requirements are taken out by the first-stage air classifier 9 and then sent to the conveying belt 10. The tobacco leaves not meeting the size requirements continue to enter the second-stage air classifier 11 through the conveying belt. In the second-stage air classifier 11, the leaves meeting the size requirements are taken out and then sent to the conveying belt 15. The material not meeting the size requirements enters the stem falling device 14. The relatively heavy tobacco stems fall and are output from the stem falling device. The relatively light stem and leaf material enters the second-stage beater 13 through the stem recycling air duct 12. The material after beating in the second-stage beater 13 enters the second-stage air classifier 11 to be classified. The classification of the material is the same as the foregoing process. The classification and beating processes in the second-stage air classifier 11 and the second-stage beater 13 are repeated until the tobacco leaves are taken out by air classification.

[0103] S4: sheet drying.

[0104] The tobacco leaves after beating are sent to the sheet drying machine 22 to be dried. The sheet drying drum of the sheet drying machine rotates and has a certain inclination angle. The wet tobacco leaves enter the sheet drying machine, rotate with the sheet drying drum, and flow out of the sheet drying drum along the direction of the inclination angle.

[0105] In this process, the hot air generated by the hot air fan passes through the steam-heated heat exchanger. The temperature of the hot air is increased to a set value and then sent to the sheet drying drum. The direction of the hot air is opposite to the direction of the material flow. Under the action of the hot air, the excess moisture in the tobacco core is discharged from the drum through the moisture discharge pipeline. The sheet drying machine outputs the dried tobacco core.

[0106] S5: flavoring.

[0107] The dried tobacco core is sent to the flavoring machine 31. The flavoring drum of the flavoring machine 31 rotates and has a certain inclination angle. The tobacco core rotates in the flavoring drum and flows out of the flavoring drum along the inclined direction. The flavoring is uniformly sprayed on the surface of the tobacco core under the action of air injection.

[0108] S6: boxing.

[0109] The eggplant cores output from the flavoring system are then packaged by auxiliary metering and packing machine 33.

[0110] The above process enables automated production of cigar filler. In addition, the production line of this invention also has great flexible processing capabilities, such as multiple production modes: full-line production mode, leaf-beating mode, leaf-beating and screening mode, and drying mode.

[0111] I. Full-line production mode:

[0112] like Figure 2 As shown, the full-line production mode refers to the production process of making qualified citrus fillers from raw tobacco through six major processes: S1 automatic feeding, S2 leaf moistening and feeding, S3 leaf blasting and air separation, S4 drying, S5 flavoring, and S6 packaging.

[0113] In the full-line production mode, the material is automatically fed through the first box-turning feeder 1, and then enters the belt scale 3 after passing through the vibrating conveyor 2. The belt scale is set with a material flow rate, and then the material enters the leaf feeder 5 through the vibrating conveyor 4.

[0114] In the leaf feeder 5, water humidifies the material through steam injection, and steam heats the material through nozzles with closed-loop hot air. The base material is evenly sprayed onto the material at the nozzles at the feed end and discharge end under the injection of steam.

[0115] After exiting the feeding drum, the material has a certain temperature and humidity, and the base material has been added. It then passes through vibrating conveyors 6 and 7 before entering the primary leaf threshing unit 8. In the leaf threshing unit, mechanical force physically tears the tobacco leaves, separating the leaves from the stems at the weakest point of the leaf's toughness, completing the leaf threshing process. The material then undergoes two air separations: a primary air separator 9 and a secondary air separator 11. Using the principle of air flotation, qualified tobacco leaves are separated from the stems and leaf-bearing stems before entering the conveyor belt 10. Unseparated material undergoes air separation at the stem dropper 14. Heavier stems fall into the stem collection device, while lighter material enters the secondary leaf threshing unit 13 through the stem return duct 12. After the secondary leaf threshing in the secondary leaf threshing unit, the material continues to enter the secondary air separator 11, repeating the above process.

[0116] Qualified tobacco sheets enter the second turning feeder 17 via conveyor belts 10, 15, and 16. After passing through belt elevator 18, belt scale 19, and vibrating conveyor 20, they enter the drying machine 22. Under the drying action of the drying machine, the moisture content of the material decreases, the curl increases, and the elasticity and filling value are improved. At the same time, as the material dries, the impurities in the tobacco leaves are discharged.

[0117] The material then passes through vibrating conveyor 23, conveyor belt 24, distributor 25, conveyor belt 27, conveyor belt 28, belt scale 29, and vibrating conveyor 30 before entering the fragrance machine 31. The fragrance is evenly sprayed onto the material at the inlet and outlet of the fragrance drum under steam injection.

[0118] The material enters the boxing machine 33 via the conveyor belt 32, and the material is weighed and boxed.

[0119] In full-line production mode, the second box-turning feeder 17 can act as a buffer. When the equipment after the second box-turning feeder 17 malfunctions, the equipment before the second box-turning feeder 17 operates normally, and materials can be stored in the second box-turning feeder 17. When the equipment before the second box-turning feeder 17 malfunctions, the equipment after the second box-turning feeder 17 operates normally, and materials can be provided from the buffer of the second box-turning feeder 17.

[0120] II. Leaf-cutting mode:

[0121] like Figure 3 As shown, the leaf-beating mode refers to the following: after the raw tobacco passes through S1 automatic feeding, S2 leaf moistening and feeding, and S3 leaf-beating air separation, the tobacco leaves separated by the two-stage air separator enter the conveyor belt 10. The conveyor belt 10 rotates in the opposite direction (horizontally to the right). The tobacco core is output at point B, and the tobacco stem is output at point C.

[0122] In the leaf feeder 5, water humidifies the material through steam injection, and steam heats the material through nozzles with closed-loop hot air. The base material is evenly sprayed onto the material at the nozzles at the feed end and discharge end under the injection of steam.

[0123] After exiting the feeding drum, the material has a certain temperature and humidity, and the base material has been added. It then passes through vibrating conveyors 6 and 7 before entering the primary leaf threshing unit 8. In the leaf threshing unit, mechanical force physically tears the tobacco leaves, separating the leaves from the stems at the weakest point of the leaf's toughness, completing the leaf threshing process. The material then undergoes two air separations: a primary air separator 9 and a secondary air separator 11. Using the principle of air flotation, qualified tobacco leaves are separated from the stems and leaf-bearing stems before entering the conveyor belt 10. Unseparated material undergoes air separation at the stem dropper 14. Heavier stems fall into the stem collection device, while lighter material enters the secondary leaf threshing unit 13 through the stem return duct 12. After the secondary leaf threshing in the secondary leaf threshing unit, the material continues to enter the secondary air separator 11, repeating the above process.

[0124] The significance of the threshing mode is that: different brands of cigar cores are different, and the types and proportions of single tobacco of different cores are different. The production of cigar has the characteristics of customization and small batch. The single tobacco can be produced in large quantities through the threshing mode. When producing different brands of cores, the mixed cores can be dried and flavored to improve the overall efficiency of the threshing line.

[0125] III. Sieving mode after threshing

[0126] As shown in Figure 4 , the sieving mode after threshing refers to that the raw tobacco is automatically fed by S1, moisturized and fed by S2, and threshed and air separated by S3. After being conveyed by the conveying belt 21, the tobacco is directly fed into the conveying belt 24 without being dried by the drying machine. The tobacco is sieved by the vibrating sieve 26 at the material distributor 25. The vibrating sieve 26 is a multi-layer sieve structure, which can sieve the cores of different sizes.

[0127] The process routes of the threshing mode and the threshing and sieving mode are basically the same. In the threshing and sieving mode, the sieving function of the core is added. The machine-made core generally does not need the sieving process. The high-quality handmade core needs to be sieved by the vibrating sieve 26 to separate the cores of different sizes. When making the handmade core, the broken tobacco and the small-sized cores are removed from the cores.

[0128] IV. Drying mode

[0129] As shown in Figure 5 , the drying mode refers to the production process of the core after the material is automatically fed by S1, dried by S4, flavored by S5 (optional), and packed by S6.

[0130] The material is automatically fed at the second box-turning feeder 17, enters the drying machine 22 at a set flow rate through the belt scale 19, and then passes through the vibrating conveyor 23, the conveying belt 24, the conveying belt 27, and the conveying belt 28. The material enters the flavoring machine 31 (flavoring can be selected) at a set flow rate through the belt scale 29, and then enters the packing machine 33 through the conveying belt 32.

[0131] In the drying mode, the material can be manually mixed by single tobacco. The mixed core can be automatically fed by the second box-turning feeder 17 to realize the drying and flavoring of the core mixed by different types of single tobacco at different proportions.

[0132] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
