Description
Technical Field
[0001] This application belongs to the technical field of tobacco processing, and particularly relates to a method for automatically controlling the cutting flow rate. Background Art
[0002] Traditional cutting operations often rely on manual operation or simple mechanical control. In the manual operation mode, operators need to manually adjust the feeding amount and the running speed of the cutting machine according to experience. This not only has a high labor intensity and low production efficiency, but also, due to the interference of human factors, it is very difficult to ensure the stability and consistency of the cutting flow rate, and it is easy to cause uneven product quality. The simple mechanical control method, although improving the production efficiency to a certain extent, lacks flexibility and accuracy. For example, its basic frequency and operating parameters are usually fixedly set and it is difficult to make real-time adjustments according to different raw material characteristics, production requirements, and actual working conditions.

[0037] Figure 2 is a flowchart of the automatic control method for cutting wire flow rate according to another optional embodiment of the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0038] The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0039] In the present embodiment, an automatic control method for cutting wire flow rate is provided. Refer to Figure 1 as shown, the method includes:
[0040] Step S101: Determine the base frequency of the feeding device.
[0041] The automatic control method for cutting wire flow provided by the embodiments of the present application can be applied to fields such as tobacco processing, and specifically can be applied to a cut tobacco production line. Among them, the cut tobacco production line mainly consists of a cutting system, a drying system, etc. The cutting system includes equipment such as a feeding device, a cutting machine, and a storage bin. This automatic control method for cutting wire flow can achieve precise regulation of the cutting wire flow by determining the base frequency of the feeding device and controlling the operation of the cutting machine according to the adjustment instruction, enabling the production line flow of the cutting system and the drying system to be highly matched, and ensuring that the cut tobacco flow produced by the cutting system can meet the processing capacity requirements of the drying system during the entire cut tobacco production process. In this way, not only can problems such as material backlog and frequent start-stop of equipment caused by flow mismatch be effectively avoided, but also the overall operation efficiency and product quality of the cut tobacco production line can be greatly improved, ensuring the continuity and stability of cut tobacco production.
[0042] In this embodiment, the feeding device can be a conveyor belt arranged on the upstream side of the cutting machine, and the main function of the conveyor belt is to convey materials to the cutting machine. The base frequency of the feeding device specifically refers to the frequency set when the conveyor belt conveys materials at the initial stage of production. This base frequency is used to determine the speed and flow of the conveyed materials, and is the basic parameter for the automatic control of the entire cutting wire flow, directly affecting the amount of materials entering the cutting machine and the stability of material conveyance.
[0043] Here, the specific steps to determine the base frequency of the feeding device are as follows: First, construct a database that stores multiple historical frequencies used by the feeding device before the cutting operation for materials with different characteristics. Then, according to the characteristics of the material to be processed, select multiple corresponding historical frequencies from the database. After that, count the start-stop times of the feeding device during the cutting operation of each corresponding material for each historical frequency, and select the historical frequency corresponding to the minimum start-stop times as the base frequency. It can be understood that for constructing the database: In actual production scenarios such as tobacco processing, the characteristics of materials (such as tobacco leaves) are diverse, including but not limited to humidity, density, toughness, etc. When cutting materials with different characteristics, in order to ensure the cutting effect and the stability of equipment operation, the feeding device will use different frequencies for material transportation. By collecting and organizing these historical data, a database is constructed for subsequent querying and analysis. The specific operation method is: During the production process, continuously record the characteristic information of the material and the frequency used by the feeding device during each cutting operation. Tools such as sensors and production management systems can be used to automatically collect this data to ensure the accuracy and integrity of the data. Classify and organize the collected data according to the material characteristics and store it in the database. A relational database (such as MySQL, Oracle, etc.) or a non-relational database (such as MongoDB, etc.) can be used to achieve data storage, and at the same time, establish appropriate data indexes for quick query; for selecting multiple corresponding historical frequencies from the database according to the characteristics of the material to be processed: When there is a new material to be processed that needs to be cut, according to the characteristics of this material, search for the matching historical frequencies in the already constructed database. Since materials with different characteristics have different requirements for cutting effects and equipment operation, it is necessary to find the corresponding historical frequencies as a reference. For example, if the tobacco leaves to be processed have a high humidity, then select the historical frequencies used by the feeding device when cutting tobacco leaves with a high humidity from the database. The specific operation method is: Accurately analyze and measure the characteristics of the material to be processed to determine its specific characteristic parameters, such as humidity, density, etc. According to the characteristic parameters of the material to be processed, perform a query operation in the database to select multiple corresponding historical frequencies. An SQL query statement or the query interface provided by the database can be used to achieve this function; for counting the start-stop times of the feeding device during the cutting operation of each corresponding material for each historical frequency and selecting the historical frequency corresponding to the minimum start-stop times as the base frequency: After selecting multiple historical frequencies corresponding to the characteristics of the material to be processed, it is necessary to further analyze the performance of each historical frequency during the operation of the feeding device. The start-stop times of the feeding device are an important indicator because frequent start-stop will cause greater wear to the equipment and also affect the stability of cutting and production efficiency.By counting the start-stop times of the feeding device at each historical frequency, select the historical frequency with the fewest start-stop times as the base frequency. This can ensure that the feeding device operates more stably during the cutting operation, reduce equipment wear, and improve production efficiency. The specific operation method is as follows: Extract the cutting operation records corresponding to each historical frequency from the database and count the start-stop times of the feeding device at this frequency. A statistical script can be written or the statistical function of the database can be used to complete this task. Compare the start-stop times corresponding to each historical frequency, and select the historical frequency corresponding to the minimum start-stop times as the base frequency of the feeding device. Apply this base frequency to the current cutting operation to ensure the stable operation of the feeding device.
[0044] Step S102: In response to the adjustment instruction, control the operating state of the cutting machine.
[0045] In this embodiment, the adjustment instruction is a control signal generated based on various feedback information in the production process (such as the pre-filling amount of the storage bin, the material flow rate adapted to the processing capacity of the drying and roasting system, etc.), and is used to adjust the operating state of the cutting machine. For example, by responding to the adjustment instruction, the rotational speed of the cutting machine's knife roller can be controlled in real time and dynamically to ensure that the cutting speed matches the production line flow rate, improving the cutting quality and production efficiency.
[0046] Here, controlling the operating state of the cutting machine specifically refers to regulating the rotational speed of the cutting machine's knife roller. Among them, the working stages of the cigarette making production line include the pre-filling stage and the production stage. In different stages, there are different adaptation requirements for the rotational speed of the knife roller. Specifically, in the pre-filling stage, the rotational speed of the cutting machine's knife roller needs to be adapted to the pre-filling amount of the storage bin. When entering the production stage, the adaptation object of the rotational speed of the cutting machine's knife roller changes to the material flow rate corresponding to the processing capacity of the drying and roasting system.
[0047] Among them, the specific steps to determine the rotational speed of the cutting machine's knife roller in the pre-filling stage are as follows: Based on the target material flow rate information, determine the pre-filling amount of the storage bin; Based on the working time and pre-filling amount in the pre-filling stage, determine the rotational speed of the cutting machine's knife roller in the pre-filling stage.
[0048] Specifically, the target material flow information is the material flow parameter determined by the entire cigarette making production line according to the production plan and product quality requirements, which is used to characterize the amount of material that the cigarette making production line needs to process per unit time. The storage bin is a container in the cigarette making production line that plays a role in buffering and storing materials. The working time of the pre-filling stage is determined according to the preheating time of the cut tobacco drying system. Here, when determining the knife roller speed of the cutting machine in the pre-filling stage, the pre-filling amount of the storage bin is determined based on the target material flow information, and this process needs to be combined with the overall planning of the cigarette making production line. For example, if the target material flow is X kilograms per hour and the preheating time of the cut tobacco drying system is T hours, considering production continuity and equipment connection, the storage bin needs to store a certain amount of materials to ensure continuous and stable feeding after the cut tobacco drying system is started. By multiplying the target material flow by the preheating time, the pre-filling amount of the storage bin can be obtained, which is set as M kilograms (M = X × T). And based on the working time and pre-filling amount of the pre-filling stage, the knife roller speed of the cutting machine in the pre-filling stage is determined, and the working efficiency of the cutting machine needs to be considered. Assume that the working time of the pre-filling stage is t hours, and the amount of cut tobacco per unit time of the cutting machine is related to the knife roller speed. Let the knife roller speed be n (unit: revolutions per minute), and the amount of cut tobacco per revolution of the cutting machine is m kilograms (this value can be determined by equipment parameters and material characteristics). Then within t hours (t hours is converted to 60t minutes), the total amount of cut tobacco of the cutting machine should be equal to the pre-filling amount M kilograms of the storage bin, and the equation can be established accordingly: 60t × n × m = M, from which the knife roller speed n = M / (60t × m) can be calculated.
[0049] Among them, the specific steps for determining the knife roller speed of the cutting machine in the production stage are as follows: obtain the cut tobacco flow information of the cutting machine in real time; compare the cut tobacco flow information with the target material flow information, and based on the comparison result, dynamically adjust the knife roller speed of the cutting machine in the production stage.
[0050] Specifically, the cut tobacco flow information (Q) of the cutting machine is used to characterize the actual quantity of cut tobacco produced by the cutting machine per unit time, and can be calculated by means of the knife gate height (h), knife gate width (w), cut tobacco width (b), number of blades (n), knife roller speed (r) and density of cut tobacco to be processed (ρ) of the cutting machine. Its specific form is: Q = h × w × b × n × r × ρ. In the production stage, the target material flow information (Q 目标 ) is preset according to the production plan and product quality requirements, representing the ideal material processing amount of the entire cigarette making production line per unit time. And the cut tobacco flow information (Q) of the cutting machine obtained in real time reflects the actual output situation of the current cutting machine. Comparing Q with Q 目标 , there will be three situations: when Q = Q 目标 , it means that the knife roller speed of the current cutting machine is in an ideal state, and can perfectly match the cut tobacco flow with the target material flow. At this time, there is no need to adjust the knife roller speed, and the current speed can be maintained to continue production to ensure the stability and continuity of production. When Q > Q目标 When it does, it means that the amount of cut tobacco produced by the cut tobacco machine exceeds the ideal demand of the cut tobacco production line during this period. To bring the cut tobacco flow rate back to the target value, it is necessary to reduce the rotational speed of the cutter roller of the cut tobacco machine. Since the cut tobacco flow rate Q is proportional to the rotational speed r of the cutter roller, by reducing the rotational speed of the cutter roller, the amount of cut tobacco produced by the cut tobacco machine per unit time can be reduced. The specific adjustment method can be to gradually reduce the rotational speed of the cutter roller according to a certain proportion. For example, each time the current rotational speed is reduced by 5%, and then the cut tobacco flow rate information Q is calculated in real time again, and compared with Q 目标 again, until Q and Q 目标 are equal or approximately equal. When Q < Q 目标 , it indicates that the output of the cut tobacco machine fails to meet the ideal flow rate demand of the cut tobacco production line. To increase the cut tobacco flow rate, it is necessary to increase the rotational speed of the cutter roller of the cut tobacco machine. Also based on the proportional relationship between Q and r, by increasing the rotational speed of the cutter roller, the amount of cut tobacco per unit time can be increased. The specific operation can be to gradually increase the rotational speed of the cutter roller. For example, each time the current rotational speed is increased by 5%, and then Q is recalculated and compared with Q 目标 until the two reach a matching state. It should be noted that by continuously obtaining the cut tobacco flow rate information in real time, comparing it with the target material flow rate information, and dynamically adjusting the rotational speed of the cutter roller according to the comparison result, it can be ensured that throughout the production stage, the cut tobacco flow rate of the cut tobacco machine always highly matches the target material flow rate, thereby ensuring the efficient and stable operation of the cut tobacco production line and improving product quality and production efficiency.
[0051] By applying the technical solution of this embodiment to determine the base frequency of the feeding device, a stable and predictable material supply speed can be provided for the cut tobacco machine, avoiding problems such as inconsistent cut tobacco thickness and fluctuating flow rate caused by uneven feeding, and improving the quality stability of the cut tobacco products. In response to the adjustment instruction, controlling the operating state of the cut tobacco machine can timely adjust the operating parameters such as the rotational speed of the cutter roller of the cut tobacco machine according to the real-time production situation, realizing dynamic and precise control of the cut tobacco flow rate to adapt to different production requirements and working condition changes. Thus, the cut tobacco speed can be matched with the production line flow rate, avoiding frequent start-stop problems of the cut tobacco machine and auxiliary connected equipment caused by material accumulation or waiting in the production line, and ensuring the continuous, stable and efficient operation of the entire cut tobacco production system.
[0052] Furthermore, as a refinement and extension of the specific implementation manner of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, another automatic cut tobacco flow rate control method is provided. See Figure 2 as shown, this method includes:
[0053] Step S201: Determine the base frequency of the feeding device;
[0054] Step S202: In response to the adjustment instruction, control the operating state of the cut tobacco machine;
[0055] Step S203: Control the operating state of the feeding device.
[0056] In this embodiment, by controlling the operating state of the feeding device, a stable and predictable material supply speed can be provided for the slicing machine, avoiding problems such as inconsistent slicing thickness and fluctuating flow rate caused by uneven feeding, and improving the quality stability of the sliced products. At the same time, it can also avoid the problem of frequent start and stop of the feeding device caused by material accumulation or waiting in the feeding device, ensuring the continuous, stable and efficient operation of the entire slicing production system.
[0057] In this embodiment, controlling the operating state of the feeding device specifically refers to regulating the operating frequency of the feeding device. Similar to the adjustment instruction for controlling the operating state of the slicing machine, the adjustment instruction for regulating the operating frequency of the feeding device is a control signal generated based on the level height of the supply bin at the inlet of the slicing machine.
[0058] Here, a supply bin for temporarily storing the material to be processed is provided at the feeding port of the slicing machine, and at least three level height sensors are equidistantly arranged along the height direction of the supply bin. The specific steps for regulating the operating frequency of the feeding device are as follows: obtain the level height information fed back by each level height sensor of the supply bin, where the level height information is the sensor position interval where the level is located; based on the level height information, adjust the operating frequency of the feeding device.
[0059] Specifically, when three level sensors are sequentially arranged in the feeding bin from bottom to top, the adjustment method of the operation frequency of the feeding device is determined by obtaining the level information feedback by each level sensor. The specific strategy is as follows: For the frequency adjustment based on the duration: When the level is between the two top level sensors and this state lasts for a preset duration, it indicates that there is a large amount of material in the feeding bin and there is a risk of overflow or accumulation. At this time, it is necessary to reduce the operation frequency of the feeding device to slow down the conveying speed of the material and avoid excessive material. For example, the operation frequency of the feeding device can be reduced to 80% - 90% of the current frequency. When the level is between the two bottom level sensors and this state remains for a preset duration, it means that there is less material in the feeding bin and the slicing machine may face a shortage of material. At this time, it is necessary to increase the operation frequency of the feeding device to speed up the conveying speed of the material and ensure sufficient material supply. For example, the operation frequency of the feeding device can be increased to 110% - 120% of the current frequency. For the frequency adjustment based on a specific position: When the level is at the position of the middle level sensor, it indicates that the amount of material in the feeding bin is within a suitable range and can meet the normal production requirements of the slicing machine. At this time, keep the operation frequency of the feeding device unchanged to ensure the stability of the material supply. When the level is higher than all three level sensors, it means that there is seriously excessive material in the feeding bin and the risk of overflow is extremely high. At this time, it is necessary to significantly reduce the operation frequency of the feeding device until the level drops to a suitable range. For example, the operation frequency of the feeding device can be reduced to 50% - 60% of the current frequency. When the level is lower than all three level sensors, it means that there is almost no material in the feeding bin and the slicing machine will soon be unable to work properly due to lack of material. At this time, it is necessary to increase the operation frequency of the feeding device to the maximum extent to quickly replenish the material. For example, the operation frequency of the feeding device can be increased to 120% - 150% of the current frequency. It should be noted that in the above strategy, the condition of maintaining the preset duration plays a key role in adjusting the operation frequency of the feeding device, mainly to avoid frequent adjustment of the operation frequency of the feeding device due to instantaneous fluctuations in the level and ensure the stability and reliability of the system operation.
[0060] It is easy for those skilled in the art to understand that, on the premise of no conflict, the above advantageous ways can be freely combined and superimposed.

Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application. The above is only the preferred implementation manner of the present application. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present application, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present application.
