Description

Technical Field

[0001] This utility model belongs to the field of tobacco stem re-drying production technology, specifically relating to a multi-path tobacco stem drying system suitable for multiple production lines. Background Technology

[0002] In the existing tobacco leaf re-drying production process, after pretreatment and moistening, the tobacco leaves enter the threshing machine to separate the leaves from the stems. The separated leaves and stems are then transported to the re-drying machine and stem roaster, respectively, for re-drying and curing processes. Typically, each threshing and curing production line is equipped with one stem roaster specifically for roasting the stems. However, as a byproduct of the threshing and re-drying process, the yield of separated stems is relatively low, and the number of stems separated from different varieties and grades of tobacco varies significantly. According to cigarette production requirements, these stems need to be roasted in batches, leading to a mismatch between the stem preparation capacity and the roasting capacity of the stem roaster. Furthermore, re-drying plants typically design their stem roasters based on maximum roasting capacity, while the stem yield in the threshing process varies considerably depending on the tobacco leaf grade, often resulting in insufficient capacity in the stem preparation stage. For example, in some special cases, no stems are produced during the production of sheet tobacco, thus eliminating the need for stem roasting. All of these factors contribute to the mismatch between the stem preparation capacity and the roasting capacity of the stem roaster.

[0003] Furthermore, existing tobacco threshing and re-drying production lines are designed so that if the stem roaster on one line malfunctions, the entire line must be shut down. This means that the threshing and pre-processing steps must also stop. This design significantly reduces production efficiency, further impacts the roasting efficiency of tobacco stems, and causes unnecessary downtime for the entire production line, resulting in energy waste.

[0004] To address the above problems, this utility model is proposed. Utility Model Content

This system enables at least two production lines to share a single tobacco stem curing machine, and its further optimized design allows multiple production lines to flexibly switch to any one of the curing machines for curing operations. This innovation significantly improves the utilization efficiency of the tobacco stem curing machine and effectively avoids production line downtime due to the malfunction of a single machine. This system maximizes the efficiency of limited resources, significantly increases the capacity of tobacco stem curing, and ensures the continuity and stability of production.

[0006] This invention, without altering the existing workshop and equipment layout, adds multiple transport devices, tobacco stem buffer cabinets, and feeders, rationally arranging these devices between the stem roasting machine and various production lines to form a flexible, multi-path roasting system.

[0018] The second tobacco stem buffer cabinet input belt 19 is a bidirectional conveyor belt, with its two ends connected to the third buffer cabinet 13 and the fourth buffer cabinet 14 respectively. The third buffer cabinet 13 and the fourth buffer cabinet 14 are also respectively provided with the third buffer cabinet output belt 131 and the fourth buffer cabinet output belt 141.

[0021] One end of the third feeder 11 and the fourth feeder 12 are respectively connected to the side of the fifth bidirectional conveyor belt 21 and the sixth bidirectional conveyor belt 22.

[0022] Specifically, the conveying direction of the third bidirectional conveyor belt 15 and / or the fourth bidirectional conveyor belt 16 is changed by switching the rotation direction of their motors. Simultaneously, one end of the third feeder 11 and the fourth feeder 12 are connected to the sides of the fifth bidirectional conveyor belt 21 and the sixth bidirectional conveyor belt 22, respectively. The tobacco stems on the third bidirectional conveyor belt 15 and the fourth bidirectional conveyor belt 16 can, in addition to achieving similar baking pathway modes as the first to fourth types, also allow the fifth bidirectional conveyor belt 21 and the sixth bidirectional conveyor belt 22 to achieve the same baking pathway as the third feeder 11 and the fourth feeder 12. The feeder 12 is connected to the first bidirectional conveyor belt 5 and the second bidirectional conveyor belt 6 respectively. That is, the tobacco stems on the third feeder 11 enter the first bidirectional conveyor belt 5 through the fifth bidirectional conveyor belt 21 and are further selected to enter the first buffer cabinet 3 or the second buffer cabinet 4, or enter the first stem roaster 10 through the first transfer belt 7 and the first roasting direct conveyor belt 8. That is, the tobacco stems on the fourth feeder 12 enter the second bidirectional conveyor belt 6 through the sixth bidirectional conveyor belt 22 and are further selected to enter the first buffer cabinet 3 or the second buffer cabinet 4, or enter the first stem roaster 10 through the first transfer belt 7 and the first roasting direct conveyor belt 8.

[0023] Preferably, the tobacco stem curing system further includes a first production line, a second production line, a third production line, and a fourth production line, and the discharge ends of the first production line, the second production line, the third production line, and the fourth production line are respectively connected to the other end of the first feeder 1, the second feeder 2, the third feeder 11, and the fourth feeder 12.

[0024] Preferably, the third production line 13 is connected to the fifth bidirectional conveyor belt 21 via the third feeder 11, and the fourth production line 14 is connected to the sixth bidirectional conveyor belt 22 via the fourth feeder 12.

[0025] Among them, the third feeder 11, the fourth feeder 12, the third buffer cabinet 13, the fourth buffer cabinet 14, the third bidirectional conveyor belt 15, the fourth bidirectional conveyor belt 16, the second transfer belt 17, the second baking direct conveyor belt 18, the second tobacco stem buffer cabinet input belt 19, the second stem roaster 20, the fifth bidirectional conveyor belt 21, and the sixth bidirectional conveyor belt 22 have a baking mode similar to that of the first feeder 1, the second feeder 2, the first tobacco stem buffer cabinet 3, the second tobacco stem buffer cabinet 4, the first bidirectional conveyor belt 5, the second bidirectional conveyor belt 6, the first transfer belt 7, the first baking direct conveyor belt 8, and the first tobacco stem buffer cabinet input belt 9. Moreover, the third feeder 11 and the fourth feeder 12 are respectively set on the sides connected to the fifth bidirectional conveyor belt 21 and the sixth bidirectional conveyor belt 22. The materials from tobacco stem buffer tanks 3 and 4 are conveyed via output belts 31 and 41 to the first baking conveyor belt 8, then via the seventh bidirectional conveyor belt 29 to the second baking conveyor belt 18, and finally to the second tobacco stem roaster 20. This achieves complete connectivity between the first, second, third, and fourth production lines, allowing tobacco stems from the first and second production lines to be buffered in buffer tanks 3 and / or 4, and ultimately dispatched to the first tobacco stem roaster 10 for baking. Furthermore, the materials in buffer tanks 3 and 4 can be directly dispatched to the second tobacco stem roaster 20 for baking via the seventh bidirectional conveyor belt 29.

[0026] In addition, to ensure efficient roasting of small batches of tobacco stems, a feeder can be added to the discharge ends of the first and second production lines, connecting to the first roasting conveyor belt 8. Similarly, a feeder can be added to the discharge ends of the third and fourth production lines, connecting to the second roasting conveyor belt 18. This allows tobacco stems requiring small-batch roasting to directly enter the stem roaster. More preferably, to further improve efficiency, a single feeder can be added to the discharge ends of the first and second production lines, connecting to the first roasting conveyor belt 8. Similarly, a single feeder can be added to the discharge ends of the third and fourth production lines, connecting to the second roasting conveyor belt 18. This ensures that if any of the feeders or stem cabinets malfunction, the tobacco stems can directly enter the stem roaster, improving system reliability.

[0027] Preferably, a first bin-type feeder 27 is provided at the connection end between the first baking conveyor belt 8 and the No. 1 stem roaster 10, and a second bin-type feeder 28 is provided at the connection end between the second baking conveyor belt 18 and the No. 2 stem roaster 20.

[0028] The first bin-type feeder 27 and the second bin-type feeder 28 respectively include a first electronic belt scale and a second electronic belt scale. The output end of the first electronic belt scale is connected to the first stem roaster 10, and the output end of the second electronic belt scale is connected to the second stem roaster 20. Both the first electronic belt scale and the second electronic belt scale are used to control the material flow rate. By adjusting the speed of the first electronic belt scale and the second electronic belt scale, the instantaneous flow rate of tobacco stems is controlled.

[0029] Preferably, the other end of the first baking conveyor belt 8 is connected to the other end of the second baking conveyor belt 18 via a seventh bidirectional conveyor belt 29.

[0030] Preferably, the tobacco stem curing system further includes a controller, and at least the first bidirectional conveyor belt 5, the second bidirectional conveyor belt 6, the first transfer belt 7, the first curing direct conveyor belt 8, the first tobacco stem buffer cabinet input belt 9, the first stem curing machine 10, the third bidirectional conveyor belt 15, the fourth bidirectional conveyor belt 16, the second transfer belt 17, the second curing direct conveyor belt 18, the second tobacco stem buffer cabinet input belt 19, the fifth bidirectional conveyor belt 21, the sixth bidirectional conveyor belt 22, the first electronic belt scale, and the second electronic belt scale are connected to the controller. The controller can realize automated management, automatically switch the curing path according to the actual production situation or preset settings, and monitor the working status of each part of the equipment in real time, further improving the reliability and intelligence level of the system.

[0031] Due to the complexity of equipment paths, to simplify tobacco stem production scheduling and reduce the complexity of tobacco stem production scheduling for operators, an optimization algorithm is adopted to automatically generate multi-production line processing path schemes for tobacco stems, meeting production constraints while achieving path optimization. Method: First, each cabinet is traversed, and its usage status is checked, including the amount of tobacco stems in the cabinet, the operating status of the stem roaster, and the operating status of equipment such as the feeder. Constraints include cabinet occupancy, whether the roaster is available, and whether the production materials are of the same grade. Then, a trial-and-error traversal method is used to schedule production for each production line. For example, if the first production line enters feeder 3, the availability of buffer cabinets 13 and 14 is checked. If buffer cabinet 13 is available, the first production line enters buffer cabinet 13. If buffer cabinets 13 and 14 are both occupied, the tobacco stems are transferred to the roaster via the second transfer belt 17, or transferred to buffer cabinet 3 or buffer cabinet 4 via the fifth bidirectional conveyor belt 21 or the sixth bidirectional conveyor belt 22, or directly roasted via the first transfer belt 7. Next, a similar scheduling process is performed on the second production line based on the remaining production resources, ultimately completing the scheduling arrangement for each production line. Finally, the optimized scheduling is manually simulated and verified. The optimized and feasible solution is then downloaded to the controller and implemented in actual production, including logic controls such as conveyor belt reversal and the selection of container outputs. This achieves optimized matching between production resources and production tasks.

[0032] The beneficial effects of this utility model are:

[0033] 1. This utility model, by setting up multiple pathways, allows tobacco stems from different production lines to be flexibly switched to different stem roasters for roasting. When a stem roaster on one production line malfunctions, tobacco stems from other production lines can enter the normal stem roaster through the alternative pathway, avoiding production stoppages and greatly improving the utilization rate of the stem roasters. Furthermore, the roasting system can flexibly adjust the conveying path of the tobacco stems according to actual needs, effectively avoiding insufficient production capacity caused by an imbalance in the amount of tobacco stems during production, and improving the overall roasting capacity.

[0034] 2. This baking system design allows multiple production lines to share one or more baking machines, flexibly adjusting the coordination between production lines. This not only saves on equipment investment but also makes production in the workshop more flexible and reliable. It effectively avoids production stoppages caused by a single production line failure. In case of a failure, production can be continued by switching to a backup route or baking machine, ensuring the continuity and stability of production and reducing losses caused by production downtime.

[0035] 3. Due to the improved utilization efficiency of the tobacco stem curing machine, more tobacco stems can be processed under the same energy consumption conditions, thereby achieving energy conservation and emission reduction and improving the efficiency of energy use. At the same time, the design of this system does not require major modifications to the existing workshop and equipment. By adopting reasonable transportation equipment and layout, it can achieve efficient multi-production line collaboration under existing conditions, greatly reducing the cost and complexity of system modification.

[0063] Using the above-described baking system, this embodiment includes at least the following tobacco stem baking modes:

[0064] Mode 1: Adjusting the transport direction of each conveyor belt using conventional methods, such as switching the motor rotation direction (forward or reverse), specifically includes: the third bidirectional conveyor belt 15, the fourth bidirectional conveyor belt 16, the second transfer belt 17, the second baking direct conveyor belt 18, and the second tobacco stem buffer cabinet input belt 19.

[0068] The tobacco stems in the fourth feeder 12 are fed into the fourth bidirectional conveyor belt 16, and then transferred by the fourth bidirectional conveyor belt 16 to the second transfer belt 17. The second transfer belt 17 continues to transport the tobacco stems to the second baking direct conveyor belt 18, and finally the second baking direct conveyor belt 18 sends the tobacco stems to the second stem roaster 20 for processing.

[0069] The above-mentioned material transportation routes refer to Figure 2 The direction of the black line with the right-angled arrow.

[0070] Mode 2: Modes 1 and 2 can be run sequentially or independently. Compared to Mode 1, the direction of the conveyor belt changes in Mode 2, as detailed below. Figure 3 The solid arrows shown indicate that the third bidirectional conveyor belt 15 and the fourth bidirectional conveyor belt 16 transport to the left, the second transfer belt 17 transports to the right, the second tobacco stem buffer cabinet input belt 19 transports upward, and the second baking direct conveyor belt 18 transports along the direction of the second stem baking machine 20.

[0071] The material transfer process is as follows: the tobacco stems in the third feeder 11 are fed into the third bidirectional conveyor belt 15, and then transferred by the third bidirectional conveyor belt 15 to the second transfer belt 17; the second transfer belt 17 continues to transport the tobacco stems to the second baking direct conveyor belt 18, and finally the second baking direct conveyor belt 18 sends the tobacco stems to the second tobacco stem roaster 20 for processing; the tobacco stems in the fourth feeder 12 are fed into the fourth bidirectional conveyor belt 16, and then transferred by the fourth bidirectional conveyor belt 16 to the second tobacco stem buffer cabinet input belt 19 to further send the tobacco stems to the third buffer cabinet 13 for buffering;

[0072] In continuous production, Mode 1 and Mode 2 can be linked. After Mode 1 has been running for a certain period, Mode 2 will start running. During this process, the tobacco stems buffered in buffer cabinet 14 of Mode 1 will also be discharged simultaneously. The tobacco stems are transferred to the second baking direct conveyor belt 18 via the output belt 141 of the fourth buffer cabinet, and finally sent to the second stem baking machine 20 for processing. The above material transportation path is as follows: Figure 3 The direction of the black line with the right-angled arrow.

[0073] Mode 3: Modes 1, 2, and 3 are performed sequentially, such as... Figure 4 As shown, compared to Mode 1, in Mode 3, the No. 3 buffer cabinet 13 simultaneously opens to convey tobacco stems outward. Specifically, the tobacco stems from the No. 3 buffer cabinet 13 are transferred via the No. 3 buffer cabinet output belt 131 to the second baking direct conveyor belt 18, and finally conveyed by this belt to the No. 2 stem baking machine 20 for processing. The above material transportation path is as follows: Figure 4 The direction of the black line with the right-angled arrow.

[0074] Mode 4: Adjust the transport direction of each conveyor belt using conventional methods, such as switching the motor rotation direction (forward or reverse). Specifically, this includes: the first bidirectional conveyor belt 5, the second bidirectional conveyor belt 6, the first transfer belt 7, the first direct drying conveyor belt 8, the first tobacco stem buffer cabinet input belt 9, the third bidirectional conveyor belt 15, the fourth bidirectional conveyor belt 16, the second transfer belt 17, the second direct drying conveyor belt 18, and the second tobacco stem buffer cabinet input belt 19. The specific operation is as follows:

[0075] according to Figure 5 The solid arrows indicate that the first bidirectional conveyor belt 5 and the second bidirectional conveyor belt 6 transport to the left, the first transfer belt 7 transports to the right, the first tobacco stem buffer cabinet input belt 9 transports upward, the first baking direct conveyor belt 8 transports along the direction of the No. 1 stem baking machine 10, the third bidirectional conveyor belt 15, the fourth bidirectional conveyor belt 16 and the second transfer belt 17 transport to the right, the second tobacco stem buffer cabinet input belt 19 transports downward, and the second baking direct conveyor belt 18 transports along the direction of the No. 2 stem baking machine 20.

[0076] The material transfer process is as follows: the tobacco stems of the first feeder 1 enter the first bidirectional conveyor belt 5 through the feeder, and the tobacco stems are then transferred by the first bidirectional conveyor belt 5 to the first transfer conveyor 7. The first transfer conveyor 7 continues to transport the tobacco stems to the first baking direct conveyor belt 8, and finally the first baking direct conveyor belt 8 sends the tobacco stems to the No. 1 stem roaster 10 for processing.

[0077] The tobacco stems from the second feeder 2 enter the second bidirectional conveyor belt 6 through feeding. The tobacco stems are then transferred by the second bidirectional conveyor belt 6 to the first tobacco stem buffer cabinet input belt 9. The first tobacco stem buffer cabinet input belt 9 further sends the tobacco stems to the second tobacco stem buffer cabinet 4 for buffering.

[0078] The tobacco stems in the third feeder 11 are fed into the third bidirectional conveyor belt 15, and then the tobacco stems are transferred by the third bidirectional conveyor belt 15 to the second tobacco stem buffer cabinet input belt 19; the second tobacco stem buffer cabinet input belt 19 further sends the tobacco stems to the fourth buffer cabinet 14 for buffering.

[0079] The tobacco stems in the fourth feeder 12 are fed into the fourth bidirectional conveyor belt 16, and then transferred by the fourth bidirectional conveyor belt 16 to the second transfer belt 17. The second transfer belt 17 continues to transport the tobacco stems to the second baking direct conveyor belt 18, and finally the second baking direct conveyor belt 18 sends the tobacco stems to the second stem roaster 20 for processing.

[0080] The above-mentioned material transportation routes refer to Figure 5 The direction of the black line with the right-angled arrow.

[0081] Mode 5: Compared to Mode 4, the direction of the conveyor belt changes in Mode 5, specifically as follows: Figure 6 The solid arrows shown indicate that the first bidirectional conveyor belt 5, the second bidirectional conveyor belt 6, and the first transfer belt 7 transport to the right, the first tobacco stem buffer cabinet input belt 9 transports downward, the third bidirectional conveyor belt 15 and the fourth bidirectional conveyor belt 16 transport to the left, the second transfer belt 17 transports to the right, and the second tobacco stem buffer cabinet input belt 19 transports upward.

[0082] During continuous production, Mode 4 and Mode 5 can be linked. After Mode 4 has been running for a certain period of time, Mode 5 will start running. In this mode, No. 2 tobacco stem buffer cabinet 4 and No. 4 buffer cabinet 14 will open and discharge materials simultaneously. The tobacco stems in No. 2 tobacco stem buffer cabinet 4 are transferred to the first baking direct conveyor belt 8 via No. 2 tobacco stem buffer cabinet output belt 41 and sent to No. 1 stem baking machine 10 for processing. The tobacco stems in No. 4 buffer cabinet 14 are transferred to the second baking direct conveyor belt 18 via No. 4 tobacco stem buffer cabinet output belt 141 and sent to No. 2 stem baking machine 20 for processing.

[0083] The above-mentioned material transportation routes refer to Figure 6 The direction of the black line with the right-angled arrow.

[0084] Mode Six: Modes Four, Five, and Six are performed sequentially, such as... Figure 7 As shown, compared to Mode 4, in Mode 6, the tobacco stems in the No. 1 tobacco stem buffer cabinet 3 and the No. 3 buffer cabinet 13 are opened simultaneously. Specifically, the tobacco stems from the No. 1 tobacco stem buffer cabinet 3 are transferred via the No. 1 tobacco stem buffer cabinet output belt 31 to the first baking direct conveyor belt 8, which then sends the tobacco stems to the No. 1 stem roaster 10 for processing. The No. 3 buffer cabinet output belt 131 transfers the tobacco stems to the second baking direct conveyor belt 18, which finally sends them to the No. 2 stem roaster 20 for processing. The above material transportation path is as follows: Figure 7 The direction of the black line with the right-angled arrow.

[0085] For more specific details, please refer to... Figure 8 As shown, the processing sequence of each production line is set according to actual needs. Line A and Line B are production line numbers. Direct roasting means that the tobacco stems are transported directly to the stem roasting machine for roasting without being buffered in the stem buffer cabinet. Out of the cabinet means that the tobacco stems are output from the stem buffer cabinet.
