Description

Technical Field

[0001] This invention relates to the field of tobacco manufacturing technology, and in particular to a combined feeding device for multiple feed hoppers containing tobacco stems and its control method. Background Technology

[0002] The quality of tobacco shreds is crucial for improving the quality of tobacco products and directly affects the quality of cigarettes. Currently, most tobacco industry feeding devices adopt a fixed "one in use, one on standby" mode, and the production process mostly uses a single feeding hopper, with each batch using only a single feeding hopper throughout the entire process.

[0003] With product diversification, the required feeding ratios vary for different stem wire grades, and some stem wire brands require more liquid than the maximum capacity of a single tank for a single batch. To meet feeding requirements, existing technologies replace the single material tank with one of larger capacity to meet high flow rate demands. However, this approach suffers from long equipment modification cycles, high costs, and a fixed single tank volume, making it unsuitable for the feeding ratios of different stem wire grades. Another technology uses a dispensing machine with dual feeding tanks for continuous feeding. When the liquid in the current tank is insufficient, manual switching to the other tank is required. The timing of this switching depends on manual experience, and the sudden transfer of liquid between tanks during the switching process can cause strong temperature and concentration fluctuations, reducing feeding uniformity and failing to meet the process requirements for uniform stem wire feeding. Summary of the Invention

[0004] This invention provides a multi-tank combined feeding device for shredded stems and its control method. By adopting a "start first, then stop" control logic according to the feeding ratio of different grades of shredded stems, it realizes automatic and seamless switching between multiple tanks for combined feeding, reduces drastic fluctuations in feeding concentration and liquid temperature during feeding switching, achieves uniform feeding of shredded stems, and meets the requirements of the production process.

[0007] Optionally, the control module is also used to control the feeding of the i-th bucket during the m-th feeding process and the feeding of the j-th bucket during the n-th feeding process when the feeding mode of the filament is determined to be a single-bucket feeding mode; where m≠n and m and n are both positive integers.

[0008] Optionally, the control module is used to control at least two buckets to feed simultaneously when the feeding mode of the stem is determined to be a multi-bucket simultaneous feeding mode.

[0009] Secondly, embodiments of the present invention provide a method for controlling the combined feeding of multiple feed hoppers for shredded stems. This method is applied to a combined feeding device for multiple feed hoppers for shredded stems, and the method includes: When the feeding mode of the filament is determined to be a multi-bucket sequential feeding mode, the feeding of the j-th bucket is controlled to start before the feeding of the i-th bucket is completed; When the j-th hopper is in the feeding state, control the i-th hopper to stop feeding.

[0010] Optionally, the multi-material tank feeding device for stems also includes at least two control valves and at least two liquid level detection modules, wherein the at least two control valves include the i-th control valve and the j-th control valve, and the at least two liquid level detection modules include the i-th liquid level detection module and the j-th liquid level detection module; The i-th control valve is located at the liquid outlet of the i-th material tank and is electrically connected to the control module. It is used to open and close according to the instructions of the control module to control the liquid output in the i-th material tank. The j-th control valve is located at the liquid outlet of the j-th material tank and is electrically connected to the control module. It is used to open and close according to the instructions of the control module to control the liquid output in the j-th material tank.

It is used to detect the liquid level information in the i-th material tank and feed it back to the control module. The j-th liquid level detection module is installed inside the j-th material tank and is electrically connected to the control module. It is used to detect the liquid level information in the j-th material tank and feed it back to the control module. When the feeding mode for the filaments is determined to be a multi-bucket sequential feeding mode, the feeding of the j-th bucket is controlled to start before the feeding of the i-th bucket ends, including: When the feeding mode of the filaments is determined to be a multi-bucket sequential feeding mode, the i-th control valve is opened; The j-th control valve is opened based on the liquid level detection information from the i-th liquid level detection module. When the j-th hopper is in the feeding state, control the i-th hopper to stop feeding, including: After a preset time has elapsed since the j-th control valve was opened, the i-th control valve is closed.

[0011] Optionally, the multi-barrel feeding control method for stems and shreds also includes: When the feeding mode of the stem is determined to be a single-bucket feeding mode, the feeding of the i-th bucket is controlled during the m-th feeding process; During the nth feeding process, control the feeding of the j-th hopper; where m≠n and m and n are both positive integers.

[0012] Optionally, before determining the feeding mode of the stems to be a multi-bucket sequential feeding mode, the following steps are also included: The total amount of feed required to obtain the stem strands; The feeding mode of the skewer is determined based on the total feeding amount, the maximum feeding threshold of a single barrel, and the feeding instruction information; the feeding modes include multi-barrel sequential feeding mode, single-channel feeding mode, and multi-barrel simultaneous feeding mode.

[0013] Optionally, the multi-barrel feeding control method for stems and shreds also includes: The feeding mode of the shredded meat is determined based on the total feeding amount, the maximum feeding threshold per barrel, and the feeding instruction information, including: The feeding mode for the stems is determined based on the total feeding amount and the maximum feeding threshold of a single barrel, either as a single-channel feeding mode or a multi-barrel feeding mode; the multi-barrel feeding mode includes sequential multi-barrel feeding mode and simultaneous multi-barrel feeding mode. When the feeding mode of the stem is determined to be a multi-barrel feeding mode, the feeding instruction information is used to determine whether the multi-barrel feeding mode is a multi-barrel sequential feeding mode or a multi-barrel simultaneous feeding mode. If the feeding mode of the stem is determined to be multi-barrel feeding mode and no feeding instruction is received within the second preset time, the multi-barrel feeding mode is determined to be multi-barrel simultaneous feeding mode.

[0014] Optionally, the total amount of feed required to obtain the stems includes: The set feeding ratio and the total weight of the stems are obtained; The total amount of feed is determined based on the feed ratio and the total weight of the stems.

[0015] This invention provides a multi-bucket combined feeding device for shredded stems. It includes a control module and at least two feeding buckets, with the i-th bucket and the j-th bucket being the two buckets. When the control module determines that the feeding mode for the shredded stems is a multi-bucket sequential feeding mode, it controls the j-th bucket to start feeding before the i-th bucket finishes feeding, and controls the i-th bucket to stop feeding while the j-th bucket is in the feeding state. Using this technical solution, the control module determines the feeding mode based on the proportion of different grades of shredded stems used, and controls multiple buckets to operate in a "start-then-stop" mode according to the feeding mode. This achieves automatic and seamless switching between multiple buckets for combined feeding, reducing drastic fluctuations in feeding concentration and liquid temperature during feeding switching, improving the stability of the feeding process, and achieving uniform feeding of shredded stems to meet production process requirements. This solves the problem that shredded stem feeding cannot meet the high flow rate requirements corresponding to high feeding ratios and the problem of uneven feeding caused by instantaneous fluctuations in liquid temperature, pressure, or flow rate during feeding switching between multiple buckets.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] Figure 1 This is a schematic diagram of a multi-tank combined feeding device for stems and fibers provided in an embodiment of the present invention. This embodiment is applicable to situations where the material supply capacity is insufficient under high feeding ratio conditions, and the feeding stability is poor due to switching between multiple tanks during production. Figure 1 As shown, the multi-bucket combined feeding device for stems includes a control module 10 and at least two buckets 20, the at least two buckets 20 including the i-th bucket 21 and the j-th bucket 22; where i ≠ j and i and j are both positive integers; the control module 10 is used to control the j-th bucket 22 to start feeding before the feeding of the i-th bucket 21 ends when the feeding mode of the stems is determined to be the multi-bucket sequential feeding mode, and to control the i-th bucket 21 to end feeding when the j-th bucket 22 is in the feeding state.

[0022] In this embodiment, the multi-tank feeding device for tobacco stems includes a control module 10 and at least two tanks 20. The control module 10 can be understood as an independent functional component responsible for receiving instructions, processing information, issuing control signals, and coordinating the operation of each component according to predetermined logic. For example, the control module 10 includes, but is not limited to, a programmable logic controller (PLC) or a computer; this embodiment of the invention does not impose any limitations on this. The tanks 20 can be understood as containers used to hold the processing liquid during the tobacco stem processing. The at least two tanks 20 include an i-th tank 21 and a j-th tank 22, where i ≠ j and i and j are both positive integers. For example, the at least two tanks 20 may include a first tank and a second tank; the at least two tanks may also include a first tank, a second tank, and a third tank; this embodiment of the invention does not impose any limitations on this.

[0023] Specifically, before initiating the feeding of a batch of stem shreds, the control module 10 obtains the set feeding ratio from the formula for that batch of stem shreds, and the total weight of the stem shreds entering the storage tank from the production data. Based on the set feeding ratio and the total weight of the stem shreds, it calculates the total amount of stem shreds required for this batch. Simultaneously, the control module 10 pre-stores a maximum feeding threshold for a single tank, representing the maximum supply capacity of a single tank. The control module 10 compares the total amount of stem shreds required for this batch with the maximum feeding threshold for a single tank, and determines the feeding mode based on the comparison result. It should be noted that the maximum feeding threshold for a single tank is 90% of the safe volume of the tank and can be manually adjusted according to the density of the liquid.

[0024] The multi-bucket feeding device for stems also includes an interaction module 50, which includes, but is not limited to, a human-machine interface (HMI). This embodiment of the invention does not impose any limitations on this. The control module 10 is electrically connected to the interaction module 50. The control module 10 outputs a feeding command to the interaction module 50 based on a comparison between the total required amount of stems and the maximum feeding threshold of a single bucket. The user selects the corresponding feeding mode according to the feeding command. When the total amount of stems exceeds the maximum feeding threshold of a single bucket, the control module 10 outputs a multi-bucket feeding mode. When the control module 10 receives a feeding command selected by the user as a multi-bucket sequential feeding mode, it immediately determines that the stem feeding mode is a multi-bucket sequential feeding mode. Before the feeding of the i-th bucket 21 ends, the control module 10 controls the j-th bucket 22 to start feeding, and while the j-th bucket 22 is in the feeding state, it controls the i-th bucket 21 to stop feeding. Through the control logic of starting feeding first and then stopping feeding, automatic and seamless switching of feeding multiple buckets is achieved.

[0025] For example, when the i-th hopper 21 is the first hopper and the j-th hopper 22 is the second hopper, and the control module 10 compares the total amount of feed required for this batch of stems and filaments to be greater than the maximum feed threshold for a single hopper, and determines that the feed mode for the stems and filaments is a multi-hopper sequential feed mode, the control module 10 first controls the first hopper to start feeding. When switching to feeding the second hopper during the feeding process of the first hopper, the control module 10 first controls the second hopper to start feeding, and then controls the first hopper to stop feeding while the second hopper is in the feeding state, thus completing the sequential feeding switch from the first hopper to the second hopper. During the feeding process, the liquid in the first and / or second buckets is fed through the manifold 1. The control module 10 controls the pump 2 to provide power, which transmits the liquid to the nozzle 4. The liquid is then sprayed onto the stems through the nozzle 4, completing the feeding of the stems. The flow meter 3 is used to record the liquid data added to each batch of stems and transmits the data to the control module 10, so that on-site personnel can understand the actual feeding situation of the stems in a timely manner.

[0026] The multi-bucket combined feeding device for stems provided in this embodiment of the invention comprises a control module 10 and at least two buckets 20, wherein the at least two buckets 20 include an i-th bucket 21 and a j-th bucket 22. When the control module 10 determines that the feeding mode of the stems is a multi-bucket sequential feeding mode, it controls the j-th bucket 22 to start feeding before the i-th bucket 21 finishes feeding, and controls the i-th bucket 21 to stop feeding when the j-th bucket 22 is in the feeding state. Using the above technical solution, the control module 10 determines the feeding mode according to the proportion of different grades of stems, and controls multiple buckets to adopt a "start first, then stop" working mode according to the feeding mode, realizing automatic and seamless switching of multiple buckets for combined feeding. This reduces drastic fluctuations in feeding concentration and liquid temperature during feeding switching, improves the stability of the feeding process, achieves uniform feeding of stems, and meets the requirements of the production process. It solves the problem that the feed of stems and fibers cannot meet the high flow rate requirements under high feed ratio conditions, and the problem of uneven feeding caused by instantaneous fluctuations in liquid temperature, pressure or flow rate during the feeding switching process of multiple feed tanks 20.

[0027] Optional, you can continue to refer to Figure 1The multi-tank feeding device for skewered shredded ingredients also includes at least two control valves 30 and at least two liquid level detection modules 40. The at least two control valves 30 include an i-th control valve 31 and a j-th control valve 32, and the at least two liquid level detection modules 40 include an i-th liquid level detection module 41 and a j-th liquid level detection module 42. The i-th control valve 31 is located at the liquid outlet of the i-th tank 21 and is electrically connected to the control module 10. It is used to open and close according to the instructions of the control module 10 to control the liquid output in the i-th tank 21. The j-th control valve 32 is located at the liquid outlet of the j-th tank 22 and is electrically connected to the control module 10. It is used to open and close according to the instructions of the control module 10 to control the liquid output in the j-th tank 22. The liquid output in 22; the i-th liquid level detection module 41 is set in the i-th material tank 21 and electrically connected to the control module 10, and is used to detect the liquid level information in the i-th material tank 21 and feed it back to the control module 10; the j-th liquid level detection module 42 is set in the j-th material tank 22 and electrically connected to the control module 10, and is used to detect the liquid level information in the j-th material tank 22 and feed it back to the control module 10; when the feeding mode of the wire is determined to be a multi-tank sequential feeding mode, the control module 10 controls the i-th control valve 31 to open, and controls the j-th control valve 32 to open according to the liquid level detection information of the i-th liquid level detection module 41; and controls the i-th control valve 31 to close after the j-th control valve 32 has been opened for a preset time.

[0028] In this embodiment, the multi-material feeding device for stems and fibers further includes at least two control valves 30 and at least two liquid level detection modules 40. A control valve 30 can be understood as an actuator in a fluid transport system that, by receiving control commands, changes the flow cross-sectional area or the on / off state of the channel to adjust and control parameters such as the flow rate or on / off state of the fluid. Exemplarily, the control valve 30 includes, but is not limited to, electric valves and solenoid valves. The at least two control valves 30 include an i-th control valve 31 and a j-th control valve 32. Exemplarily, the at least two control valves 30 may include a first control valve and a second control valve. The at least two control valves may also include a first control valve, a second control valve, and a third control valve; this embodiment of the invention does not impose limitations in this regard.

[0029] Specifically, the number of at least two control valves 30 corresponds to the number of at least two material tanks 20. The i-th control valve 31 is located at the liquid outlet of the i-th material tank 21 and is electrically connected to the control module 10. The i-th control valve 31 can receive opening and closing commands from the control module 10 and open and close accordingly to control the output and stop of liquid in the i-th material tank 21. The j-th control valve 32 is located at the liquid outlet of the j-th material tank 22 and is electrically connected to the control module 10. The j-th control valve 32 can receive opening and closing commands from the control module 10 and open and close accordingly to control the output and stop of liquid in the j-th material tank 22.

[0030] The liquid level detection module 40 can be understood as a functional element used to monitor in real time whether the liquid height or level in the container has reached a preset threshold, and to convert the liquid level information into an electrical signal or a digital signal for output. For example, the liquid level detection module 40 includes, but is not limited to, a liquid level sensor; this embodiment of the invention does not impose such limitations. At least two liquid level detection modules 40 include an i-th liquid level detection module 41 and a j-th liquid level detection module 42, wherein the number of liquid level detection modules 40 corresponds to the number of material tanks 20. For example, when at least two material tanks 20 include a first material tank and a second material tank, the at least two liquid level detection modules 40 include a first liquid level detection module and a second liquid level detection module.

[0031] Specifically, the i-th liquid level detection module 41 is installed inside the i-th material tank 21 and electrically connected to the control module 10. The i-th liquid level detection module 41 detects the liquid level information of the i-th material tank 21 and transmits the detected liquid level information of the i-th material tank 21 to the control module 10. The j-th liquid level detection module 42 is installed inside the j-th material tank 22 and electrically connected to the control module 10. After detecting the liquid level information of the j-th material tank 22, the j-th liquid level detection module 42 transmits the liquid level information of the j-th material tank 22 to the control module 10, so that the control module 10 can obtain the remaining liquid level in each material tank in a timely manner.

[0032] The control module 10 has a preset minimum liquid level detection threshold for a single tank. When the feeding mode of the filaments is determined to be a multi-tank sequential feeding mode, after controlling the opening of the i-th control valve 31, the control module 10 receives the liquid level detection information from the i-th liquid level detection module 41 and compares the liquid level detection information of the i-th liquid level detection module 41 with the minimum liquid level detection threshold for a single tank. When the liquid level detection information of the i-th liquid level detection module 41 reaches the minimum liquid level detection threshold for a single tank, the control module 10 controls the opening of the j-th control valve 32. The control module 10 is also equipped with a timing unit, which includes, but is not limited to, a timing circuit and a timing program, and this embodiment of the invention does not limit this. After controlling the opening of the j-th control valve 32, the control module 10 starts timing, and after the opening time of the j-th control valve 32 reaches a preset time, it controls the closing of the i-th control valve 31, so that the feeding of the i-th material tank 21 stops, realizing the sequential switching from feeding from the i-th material tank 21 to feeding from the j-th material tank 22.

[0033] For example, when the i-th material tank 21 and the j-th material tank 22 are the first material tank and the second material tank, respectively, then the i-th control valve 31 and the j-th control valve 32 are the corresponding first control valve and second control valve, respectively. The first material tank is equipped with a first liquid level detection module, and the second material tank is equipped with a second liquid level detection module, allowing for combined feeding of the filaments into both material tanks. When the control module 10 determines that the feeding mode of the filaments is a dual-tank sequential feeding mode, after controlling the first control valve to open, the control module 10 receives the liquid level detection information from the first liquid level detection module and compares the liquid level detection information from the first liquid level detection module with the lowest liquid level detection threshold of a single tank. When the liquid level detection information of the first liquid level detection module reaches the minimum liquid level detection threshold of a single tank, the control module controls the second control valve to open. At this time, the first and second tanks are fed synchronously. After the second control valve is opened, the timing starts. When the second control valve is open for a preset time, the control module 10 controls the first control valve to close, so that the first tank stops feeding and the second tank is fed independently.

[0034] The multi-tank feeding device for stems provided in this embodiment of the invention includes at least two control valves 30 and at least two liquid level detection modules 40. The control valves 30 are respectively located at the liquid outlets of at least two tanks 20 and are electrically connected to a control module 10, used to open and close according to instructions from the control module 10. The liquid level detection modules 40 are respectively located in at least two tanks 20 and are electrically connected to the control module 10, used to detect the liquid level information in the tanks 20 and feed it back to the control module 10. When the control module 10 determines that the stem feeding mode is a multi-tank sequential feeding mode, it can automatically complete the continuous actions of opening the previous tank, starting the next tank, and closing the previous tank according to the real-time liquid level information of each tank, ensuring a continuous, stable, and uninterrupted multi-tank feeding process. The liquid level detection module 40 provides real-time feedback on the remaining liquid level in the material tank 20. The control module 10 controls the control valve 30 based on this information, automatically switching between multiple material tanks 20 for feeding. This improves the accuracy of feeding control and production efficiency. It solves the problem of inaccurate feeding and low production efficiency caused by the inability to obtain real-time liquid level information during the switching process between multiple material tanks 20, which resulted in a lack of data support for tank switching and reliance on manual experience for switching time.

[0035] Optional, you can continue to refer to Figure 1 The control module 10 is also used to control the i-th bucket 21 to add material during the m-th feeding process and to control the j-th bucket 22 to add material during the n-th feeding process when the feeding mode of the filament is determined to be a single bucket feeding mode; where m ≠ n and m and n are both positive integers.

[0036] In this embodiment, the feeding mode of the stems also includes a single-bucket feeding mode, which can be understood as a working mode in which a single batch of stems is fed by only one bucket 20.

[0037] Specifically, the single-bucket feeding mode is generally used in situations with low feeding ratios. When the total feeding amount of the current batch of stems calculated by the control module 10 is lower than the maximum feeding threshold of a single bucket, the multi-bucket combined feeding device for stems does not issue a prompt, and the feeding mode for the stems is determined to be the single-bucket feeding mode by default. The control module 10 opens the control valve 30 of one bucket, and the corresponding bucket 20 independently feeds until the feeding is completed, without needing to switch during the feeding process. The single-bucket feeding mode uses single-bucket rotation feeding, that is, during the m-th feeding process, the i-th bucket 21 is controlled to feed, and during the n-th feeding process, the j-th bucket 22 is controlled to feed, where m ≠ n and m and n are both positive integers.

[0038] For example, when the control module 10 determines that the feeding mode of the filaments is a single-bucket feeding mode, and m is 1 and n is 2, that is, if the i-th hopper 21 is controlled to feed independently during the first feeding process, then the j-th hopper 22 is controlled to feed independently during the second feeding process; that is, if the j-th hopper 22 is controlled to feed independently during the first feeding process, then the i-th hopper 21 is controlled to feed independently during the second feeding process.

[0039] The multi-bucket combined feeding device for shredded stems provided in this embodiment of the invention, by setting a single-bucket feeding mode, allows the control module 10 to execute the control logic of single-bucket alternating feeding when the feeding mode for shredded stems is determined to be a single-bucket feeding mode. Specifically, during the m-th feeding process, the i-th bucket 21 is controlled to feed alone, and during the n-th feeding process, the j-th bucket 22 is controlled to feed alone. This configuration allows multiple buckets 20 to operate simultaneously, improving the utilization rate of the feeding device while balancing the load on each bucket 20 and the control valve 30. It also prevents a single bucket 20 from operating for extended periods, extending the overall service life of the multi-bucket combined feeding device for shredded stems. This solves the problem of aging and low utilization rate of the multi-bucket combined feeding device caused by multiple buckets 20 being idle for extended periods.

[0040] Optional, you can continue to refer to Figure 1 The control module 10 is used to control at least two material buckets 20 to feed simultaneously when the feeding mode of the filaments is determined to be a multi-bucket simultaneous feeding mode.

[0041] In this embodiment, the multi-bucket simultaneous feeding mode also includes feeding at least two buckets 20 at the same time. The simultaneous feeding of at least two buckets 20 can be understood as a working mode in which multiple buckets 20 are fed simultaneously in a single batch of stem feeding.

[0042] Specifically, when the total amount of stems added in this batch calculated by the control module 10 exceeds the maximum addition threshold for a single barrel, the multi-barrel combined feeding device for stems issues a prompt indicating that only the multi-barrel simultaneous feeding mode can be used. The device also outputs a feeding command for the multi-barrel simultaneous feeding mode through the interaction module 50, which includes simultaneous feeding of at least two barrels 20. When the control module 10 receives a user-selected feeding command for simultaneous feeding of at least two barrels 20, it controls the control valves 30 of at least two barrels to open simultaneously, allowing simultaneous feeding of at least two barrels 20. Simultaneously, it controls the control valves 30 of at least two barrels to close simultaneously, ending feeding of at least two barrels 20.

[0043] For example, when the control module 10 controls at least two material tanks 20 to feed simultaneously, the control module 10 simultaneously issues an "open" command to the i-th control valve 31 and the j-th control valve 32, and the i-th material tank 21 and the j-th material tank 22 begin feeding simultaneously. During the entire batch of wire production, the liquid material in the i-th material tank 21 and the j-th material tank 22 are consumed simultaneously. When feeding ends, the control module 10 simultaneously issues a "close" command to the i-th control valve 31 and the j-th control valve 32, causing the i-th material tank 21 and the j-th material tank 22 to stop feeding simultaneously, ensuring the integrity of feeding and the stability of the feeding process.

[0044] The multi-tank combined feeding device for stems provided in this embodiment of the invention, when the control module 10 determines that the feeding mode of the stems is a multi-tank simultaneous feeding mode, controls at least two tanks 20 to feed simultaneously, realizing a feeding mode where multiple tanks 20 feed at the same time. This increases the feeding flow rate per unit time, meets the production demand for large flow rates, and improves the feeding efficiency of stems. At the same time, it ensures the integrity and stability of the feeding process, preventing production accidents caused by the mid-process depletion of slurry from the source. This solves the problem that stem feeding devices cannot achieve simultaneous feeding of multiple tanks 20, thus failing to meet the needs of large flow rates.

[0045] Based on the same inventive concept, this invention also provides a method for controlling the combined feeding of stem fibers into multiple feed tanks. Figure 2 This is a flowchart illustrating a method for controlling the combined feeding of multiple stem and shredded shredded hampers using an embodiment of the present invention. This method can be applied to any of the optional embodiments of the above-described combined feeding device for multiple stem and shredded shredded hampers. Figure 2 As shown, the multi-barrel feeding control method for stem fibers includes: S101. When the feeding mode of the filament is determined to be a multi-bucket sequential feeding mode, the j-th bucket is controlled to start feeding before the feeding of the i-th bucket is completed.

[0046] Specifically, the multi-barrel feeding device for stems includes a control module and at least two barrels, including an i-th barrel and a j-th barrel, wherein the i-th barrel and the j-th barrel are different barrels. For example, the i-th barrel and the j-th barrel can be the first barrel and the second barrel, and this embodiment of the invention does not limit this.

[0047] When the control module receives the user's selected multi-bucket sequential feeding command, it immediately determines that the feeding mode for the wire is multi-bucket sequential feeding mode. Before the feeding of the i-th bucket is completed, the control module controls the j-th bucket to start feeding. That is, when the i-th bucket is in the feeding state, the j-th bucket starts feeding, and before the bucket switching feeding is completed, the i-th bucket and the j-th bucket are fed together for a period of time.

[0048] S102. When the j-th hopper is in the feeding state, control the i-th hopper to stop feeding.

[0049] Specifically, when the j-th hopper is in the feeding state, the control module controls the i-th hopper to stop feeding. At this time, the feeding of the i-th and j-th hoppers is switched to the j-th hopper feeding independently, completing a seamless sequential switch from feeding the i-th hopper independently to feeding the j-th hopper independently.

[0050] The multi-bucket joint feeding control method for stem filaments provided in this invention, when the feeding mode of the stem filaments is determined to be a multi-bucket sequential feeding mode, controls the j-th bucket to start feeding before the i-th bucket finishes feeding, and controls the i-th bucket to stop feeding while the j-th bucket is in the feeding state. Based on the feeding mode, the multiple buckets are controlled to adopt a "start first, then stop" working mode, realizing automatic and seamless switching between multiple buckets for joint feeding. This reduces drastic fluctuations in feeding concentration and liquid temperature during feeding switching, improves the stability of the feeding process, and achieves uniform feeding of stem filaments, meeting the requirements of the production process. It solves the problem that stem filament feeding cannot meet the high flow rate requirements corresponding to high feeding ratio conditions and the problem of uneven feeding caused by instantaneous fluctuations in liquid temperature, pressure, or flow rate during the feeding switching process of multiple buckets.

[0051] Figure 3This is a flowchart of another method for controlling the combined feeding of multiple feed hoppers for stems provided in this embodiment of the invention. Based on the above implementation method, this embodiment elaborates in detail on the specific control method for controlling the start of feeding of the j-th feed hopper before the feeding of the i-th feed hopper ends and the specific control method for controlling the end of feeding of the i-th feed hopper when the j-th feed hopper is in the feeding state. The multi-tank feeding device for stems and fibers includes at least two control valves and at least two liquid level detection modules. The at least two control valves include an i-th control valve and a j-th control valve, and the at least two liquid level detection modules include an i-th liquid level detection module and a j-th liquid level detection module. The i-th control valve is located at the liquid outlet of the i-th tank and electrically connected to the control module, used to open and close according to the instructions of the control module to control the liquid output from the i-th tank. The j-th control valve is located at the liquid outlet of the j-th tank and electrically connected to the control module, used to open and close according to the instructions of the control module to control the liquid output from the j-th tank. The i-th liquid level detection module is located inside the i-th tank and electrically connected to the control module, used to detect the liquid level information in the i-th tank and feed it back to the control module. The j-th liquid level detection module is located inside the j-th tank and electrically connected to the control module, used to detect the liquid level information in the j-th tank and feed it back to the control module. Figure 3 As shown, the method specifically includes: S201. When the feeding mode of the filaments is determined to be a multi-bucket sequential feeding mode, control the i-th control valve to open.

[0052] Specifically, a control valve can be understood as an actuator in a fluid transport system that receives control commands and changes the flow cross-sectional area or the on / off state of the channel to adjust and control parameters such as the flow rate or on / off state of the fluid. The i-th control valve is located at the liquid outlet of the i-th material tank and is electrically connected to the control module. When the control module determines that the feeding mode of the wire is a multi-tank sequential feeding mode, it sends an opening control command to the i-th control valve. After receiving the opening command from the control module, the i-th control valve opens, allowing the liquid in the i-th material tank to be output.

[0053] S202. Control the j-th control valve to open based on the liquid level detection information of the i-th liquid level detection module.

[0054] Specifically, the liquid level detection module can be understood as a functional element used to monitor in real time whether the liquid height or level in the container has reached a preset threshold, and to convert the liquid level information into an electrical signal or a digital signal for output. The i-th liquid level detection module is set in the i-th container and electrically connected to the control module. The i-th liquid level detection module detects the liquid level information in the i-th container and transmits the detected liquid level information in the i-th container to the control module.

[0055] The control module has a preset minimum liquid level detection threshold for a single tank. When the control module determines that the feeding mode of the filament is a multi-tank sequential feeding mode, after controlling the i-th control valve to open, the control module receives the liquid level detection information from the i-th liquid level detection module and compares the liquid level detection information of the i-th liquid level detection module with the minimum liquid level detection threshold for a single tank. When the liquid level detection information of the i-th liquid level detection module reaches the minimum liquid level detection threshold for a single tank, the control module controls the j-th control valve to open. At this time, the i-th tank and the j-th tank are fed together.

[0056] S203. After the j-th control valve has been open for a preset time, control the i-th control valve to close.

[0057] Specifically, the control module also includes a timing unit, which includes, but is not limited to, a timing circuit and a timing program; this embodiment of the invention does not impose any limitations on these. After the j-th control valve is opened, the control module starts timing, and after the j-th control valve has been open for a preset time, it controls the i-th control valve to close, stopping the feeding of the i-th hopper and allowing the j-th hopper to be fed independently, thus switching the feeding process from the i-th hopper to the j-th hopper.

[0058] The multi-bucket joint feeding control method for stems provided in this invention, when the feeding mode of the stems is determined to be a multi-bucket sequential feeding mode, controls the i-th control valve to open. Then, the control module controls the j-th control valve to open based on the liquid level detection information of the i-th liquid level detection module, and controls the i-th control valve to close after a preset time after the j-th control valve opens. Based on the stem feeding mode and the real-time liquid level information of each bucket, the continuous actions of opening the previous bucket feeding, starting the next bucket feeding, and then closing the previous bucket are automatically completed, ensuring a continuous, stable, and uninterrupted multi-bucket feeding process. Real-time feedback of the remaining liquid level in the buckets is provided through liquid level detection, and the control valves are controlled based on this information to automatically switch between feeding multiple buckets, improving the accuracy of feeding control and production efficiency. This solves the problems of inaccurate feeding and low production efficiency caused by the inability to obtain real-time liquid level information during the switching process between multiple buckets, resulting in a lack of data support for bucket switching and reliance on manual experience for switching time.

[0059] Figure 4 This is a flowchart of another method for controlling the combined feeding of stems and shreds in multiple buckets, provided by an embodiment of the present invention. This embodiment elaborates on the control method of the single-bucket feeding mode based on the above-described implementation. For example... Figure 4 As shown, the multi-barrel feeding control method for stems and shreds also includes: S301. When the feeding mode of the filament is determined to be single-bucket feeding mode, the feeding of the i-th bucket is controlled during the m-th feeding process.

[0060] Specifically, the single-bucket feeding mode is generally used in working conditions with low feeding ratios. The single-bucket feeding mode adopts a method of feeding one bucket at a time, that is, only one bucket is activated for feeding at the same time. When the feeding mode of the wire is determined to be the single-bucket feeding mode, the control module only activates the i-th bucket for feeding during the m-th feeding process, while the other buckets remain closed.

[0061] S302. Control the feeding of the j-th hopper during the n-th feeding process; where m≠n and m and n are both positive integers.

[0062] Specifically, after the m-th feeding is completed, when the n-th feeding is performed, the control module only activates the j-th hopper for feeding, while the other hoppers remain closed. Here, m and n are distinct positive integers.

[0063] For example, when the control module determines that the feeding mode of the filaments is a single-bucket feeding mode, and m is 3 and n is 4, that is, if the i-th bucket is controlled to feed independently during the 3rd feeding process, then the j-th bucket will be controlled to feed independently during the 4th feeding process.

[0064] The multi-bucket combined feeding control method for stems provided in this invention, when determining that the feeding mode for stems is a single-bucket feeding mode, controls the feeding of the i-th bucket during the m-th feeding process and controls the feeding of the j-th bucket during the n-th feeding process. A rotation control logic is used during single-bucket feeding, allowing multiple buckets to work alternately according to the feeding frequency. This improves the utilization rate of the feeding device while balancing the load on each bucket and control valve, avoiding prolonged operation of a single bucket and extending the overall service life of the device. This solves the problem of fatigue aging and shortened service life caused by long-term continuous operation of a single bucket, while also avoiding resource waste caused by prolonged idleness of some buckets.

[0065] Figure 5 This is a flowchart of another method for controlling the combined feeding of stems and shreds in multiple buckets according to an embodiment of the present invention. This embodiment elaborates on the steps prior to determining the feeding mode of the stems and shreds as a multi-bucket sequential feeding mode, based on the above-described implementation. For example... Figure 5 As shown, the method specifically includes: S401. Obtain the total amount of feed required for the stems.

[0066] Specifically, before initiating the feeding of a batch of stem shreds, the control module obtains the total amount of material required for that batch. This total amount can be understood as the total volume of liquid material needed to achieve the preset proportions or process requirements in a single feeding operation. By determining the feeding mode based on the total amount, the stem shred feeding process can be flexibly planned according to the total material demands of the batch production task.

[0067] Optionally, specific methods for obtaining the total amount of feed required for the stems include: The set feeding ratio and the total weight of the stems are obtained.

[0068] Specifically, before starting the feeding of a batch of stems, the control module will obtain the set feeding ratio from the formula of that batch of stems, the total weight of the stems entering the storage cabinet from the production data, and calculate the total amount of stems required for this batch based on the set feeding ratio and the total weight of the stems.

[0069] The total amount of feed is determined based on the feed ratio and the total weight of the stems.

[0070] Specifically, after obtaining the feeding ratio and the total weight of the stems, the total feeding amount is determined based on the feeding ratio and the total weight of the stems. The total feeding amount is the product of the feeding ratio and the total weight of the stems.

[0071] For example, if before initiating batch feeding of stems, the control module obtains a set feeding ratio R_set=5% from the formula, and the total weight of the batch of stems MB_Total=4000 kg. The control module calculates the total feeding amount F_Total=5%×4000=200 kg based on the feeding ratio R_set and the total weight of the stems MB_Total, where the maximum feeding threshold per barrel is 150 kg. If the control module compares the total feeding amount (200 kg) with the maximum feeding threshold of 150 kg per barrel, it determines that the single-barrel capacity is insufficient and a multi-barrel feeding mode must be activated.

[0072] S402. Confirm the feeding mode of the filament based on the total feeding amount, the maximum feeding threshold of a single barrel, and the feeding instruction information; the feeding mode includes multi-barrel sequential feeding mode, single-channel feeding mode, and multi-barrel simultaneous feeding mode.

[0073] Specifically, the control module pre-stores a maximum feeding threshold for a single tank, representing the maximum supply capacity of each tank. After obtaining the total feeding amount, the control module compares the total feeding amount required for this batch of stems with the maximum feeding threshold for a single tank to determine the feeding mode. It should be noted that the maximum feeding threshold for a single tank is 90% of the safe volume of the tank and can be manually adjusted according to the density of the liquid material.

[0074] The control module outputs a feeding command based on a comparison between the total amount of feed required for the stems and the maximum feeding threshold for a single container. The user selects the corresponding feeding module according to the feeding command. The control module confirms the final feeding mode for the stems based on the input feeding command information: multi-container sequential feeding mode, single-container feeding mode, or multi-container simultaneous feeding mode. When the total feeding amount exceeds the maximum feeding threshold for a single container, it indicates that a single container cannot complete the task independently, and the control module outputs either multi-container sequential feeding mode or multi-container simultaneous feeding mode. When the total feeding amount is less than or equal to the maximum feeding threshold for a single container, it indicates that the capacity of a single container is sufficient to ensure the integrity of this batch of feeding, and the control module defaults to single-container feeding mode, controlling the feeding of a single container.

[0075] S403. When the feeding mode of the filament is determined to be a multi-bucket sequential feeding mode, the j-th bucket is controlled to start feeding before the feeding of the i-th bucket is completed.

[0076] S404. When the j-th hopper is in the feeding state, control the i-th hopper to stop feeding.

[0077] The multi-bucket joint feeding control method for stems provided in this invention, before determining whether the feeding mode is a multi-bucket sequential feeding mode, obtains the set feeding ratio and the total weight of the stems, and then determines the total feeding amount based on the feeding ratio and the total weight of the stems. This achieves automated and precise determination of the total feeding amount, ensuring that the feeding amount strictly matches the actual demand for stems. This solves the problems of errors and low accuracy that easily occur when manually setting the feeding amount, and also addresses the issue of feeding control failing to meet actual production needs, resulting in poor applicability and low production efficiency. The feeding mode—whether it is a multi-bucket sequential feeding mode, a single-channel feeding mode, or a multi-bucket simultaneous feeding mode—is confirmed based on the total feeding amount, the maximum feeding threshold for a single bucket, and the feeding instruction information. By automatically determining the automated working mode of the feeding mode based on the total feeding amount required for the current batch, proactive decision-making based on the total batch feeding demand is achieved. This ensures that the feeding operation for any batch can be executed completely and continuously, adapting to high-volume production scenarios, improving feeding accuracy and efficiency. This solves the problem of low feeding efficiency caused by the inability of traditional feeding methods to predict the feeding amount and determine the feeding mode based on actual production needs.

[0078] Figure 6 This is a flowchart of another method for controlling the combined feeding of stems in multiple buckets according to an embodiment of the present invention. Based on the above-described implementation, this embodiment elaborates on the specific process of confirming the feeding mode of the stems according to the total feeding amount, the maximum feeding threshold of a single bucket, and the feeding instruction information. Figure 6 As shown, the method includes: S501, Obtain the total amount of feed required for the stems.

[0079] S502. Determine the feeding mode of the stems or the multi-barrel feeding mode based on the total feeding amount and the maximum feeding threshold of a single barrel. The multi-barrel feeding mode includes the multi-barrel sequential feeding mode and the multi-barrel simultaneous feeding mode.

[0080] Specifically, when the total amount of material added exceeds the maximum addition threshold for a single bucket, it indicates that a single bucket cannot complete the task independently. The control module outputs a multi-bucket addition mode, which includes sequential addition and simultaneous addition. In sequential addition mode, the control module initiates addition to the j-th bucket before the i-th bucket finishes adding material, and stops adding material to the i-th bucket while the j-th bucket is adding material. In simultaneous addition mode, the control module simultaneously opens the control valves of at least two buckets (i-th and j-th) to add material to at least two buckets simultaneously, and simultaneously closes the control valves of at least two buckets (i-th and j-th) to stop adding material to at least two buckets simultaneously.

[0081] S503. When the feeding mode of the stem is determined to be a multi-barrel feeding mode, the feeding instruction information is used to determine whether the multi-barrel feeding mode is a multi-barrel sequential feeding mode or a multi-barrel simultaneous feeding mode.

[0082] Specifically, when the feeding mode of the stem is determined to be the multi-barrel feeding mode, the control module outputs feeding instruction information for the multi-barrel sequential feeding mode and the multi-barrel simultaneous feeding mode through the interaction module. The user can choose the multi-barrel sequential feeding mode or the multi-barrel simultaneous feeding mode to feed.

[0083] For example, when the total amount of material added exceeds the maximum addition threshold for a single container, the interactive module outputs a warning window: "The total amount of material added in the batch exceeds the maximum addition threshold for a single container. Multi-container addition mode has been activated. Please select the addition command: [A. Multi-container sequential addition mode], [B. Multi-container simultaneous addition mode]." The operator inputs the corresponding addition command through the interactive module. The addition command is transmitted to the control module, which determines the multi-container addition mode based on the command and controls the corresponding container to add material.

[0084] S504. When it is determined that the feeding mode of the stem is a multi-barrel feeding mode and no feeding instruction information is received within the second preset time, the multi-barrel feeding mode is determined to be a multi-barrel simultaneous feeding mode.

[0085] Specifically, after determining that the feeding mode for the stems is a multi-barrel feeding mode, the interaction module outputs a feeding command. The operator needs to confirm the feeding command within a second preset time. If the control module does not receive the feeding command information after the second preset time has elapsed, it defaults to a multi-barrel simultaneous feeding mode. For example, the second preset time may include, but is not limited to, 30 seconds; this embodiment of the invention does not impose any limitation on this.

[0086] The multi-bucket joint feeding control method for stems provided in this invention determines the feeding mode (single-channel feeding mode or multi-bucket feeding mode) based on the total required feeding amount of stems and the maximum feeding threshold of a single bucket after obtaining the total feeding amount. When the multi-bucket feeding mode is determined, it is further determined to be either a sequential feeding mode or a simultaneous feeding mode based on the feeding instruction information. Furthermore, if the multi-bucket feeding mode is determined and no feeding instruction information is received within a second preset time, the simultaneous feeding mode is selected. Feeding is performed according to actual production, providing selectable collaborative working modes. After the system automatically determines that multi-bucket feeding needs to be activated, operators are allowed to flexibly choose between sequential or simultaneous feeding modes based on actual production conditions. This integrates automation with human experience, achieving an optimal joint feeding strategy and improving feeding efficiency. It solves the problems of traditional fixed feeding modes being unable to adapt to actual production conditions and lacking flexibility.

When it is determined that the feeding mode of the stem is a multi-barrel feeding mode, the feeding instruction information determines whether the multi-barrel feeding mode is a multi-barrel sequential feeding mode or a multi-barrel simultaneous feeding mode. If the feeding mode of the stem is determined to be a multi-barrel feeding mode and no feeding instruction information is received within a second preset time, the multi-barrel feeding mode is determined to be the multi-barrel simultaneous feeding mode.

10. The method for controlling the combined feeding of stems and shreds in multiple material bins according to claim 8, characterized in that, The total amount of feed required to obtain the stem strands includes: The set feeding ratio and the total weight of the stems are obtained; The total amount of material added is determined based on the added ratio and the total weight of the stems.
