[0021] Figure 1 This is a flowchart illustrating a method for controlling the packaging of expanded tobacco shreds according to an embodiment of the present invention. This embodiment is applicable to automated operations of packaging expanded tobacco shreds in the tobacco industry. The method for controlling the packaging of expanded tobacco shreds is applied to a packaging device for expanded tobacco shreds. The packaging device includes a shred feeding and conveying module and a control module, with the control module electrically connected to the shred feeding and conveying module. Figure 1 As shown, the packaging control method for expanded tobacco includes: S110. Obtain the packing weight information of expanded tobacco.

[0022] Specifically, the packing device for expanded tobacco includes a weight detection module, which is located below the tobacco boxes to be loaded in the tobacco box conveyor track. The weight detection module can be understood as a single functional module capable of collecting and outputting weight information in real time. The weight detection module is electrically connected to the control module. After the expanded tobacco is loaded into the tobacco box, the weight detection module measures the current packing weight of the expanded tobacco in real time and transmits this weight information to the control module, which then receives the packing weight information.

[0023] The packing weight information can be understood as the weight of the tobacco box measured by the weight detection module after the expanded tobacco shreds enter the tobacco box to be loaded.

[0024] S120. Control the operating frequency of the wire feeding module according to the packing weight information.

[0025] Specifically, the tobacco feeding and conveying module can be understood as the material conveying mechanism in the expanded tobacco packing device. After the control module obtains the packing weight information, it sets the operating frequency of the tobacco feeding and conveying module according to the packing weight information. The tobacco feeding and conveying module continuously feeds the expanded tobacco to the tobacco boxes to be loaded according to the operating frequency. The control module adjusts the operating frequency of the tobacco feeding and conveying module according to the real-time packing weight information to achieve graded control of fast feeding, slow feeding, micro-replenishment feeding and stopping feeding, so that the expanded tobacco conveyed by the tobacco feeding and conveying module is efficiently delivered to the tobacco boxes to be loaded while avoiding the tobacco boxes from overflowing.

[0026] For example, the rated packing weight of the tobacco box to be loaded is set to 12.0 kg ± 0.5 kg. When the control module receives a packing weight of 5 kg, it confirms that the current packing weight is much less than the rated packing weight of the tobacco box. Therefore, the control module increases the operating frequency of the tobacco feeding module to quickly transport the expanded tobacco to the tobacco box, improving the packing efficiency. When the control module receives a packing weight of 11.8 kg, it confirms that the current packing weight is close to the rated packing weight of the tobacco box. Therefore, the control module decreases the operating frequency of the tobacco feeding module to slow down the transport of the expanded tobacco to the tobacco box, allowing it to be loaded slowly and preventing the tobacco box from overflowing.

[0027] The packing control method for expanded tobacco provided in this invention is applied to a packing device for expanded tobacco. The packing device includes a tobacco feeding and conveying module and a control module, with the control module electrically connected to the tobacco feeding and conveying module. The packing control method includes: acquiring the packing weight information of the expanded tobacco, and then controlling the operating frequency of the tobacco feeding and conveying module according to the packing weight information. Using the above technical solution, the packing device can automatically adjust the operating frequency of the tobacco feeding and conveying module according to the packing weight information, achieving automated and precise packing of expanded tobacco. The integrated design of tobacco feeding, weighing, and packing improves the intelligence level of the tobacco production logistics process, reduces manual labor intensity, reduces packing weight deviation and raw material loss, and ensures the safety of expanded tobacco packing operations. It solves the problems of low automation, low efficiency, poor weighing accuracy, and significant safety hazards caused by manual labor in the processes of feeding, weighing, and packing of expanded tobacco.

[0028] Optionally, the operating frequency of the wire feeding module can be controlled based on the packing weight information, including: Within a preset weight range, the operating frequency is negatively correlated with the packing weight information.

[0029] Specifically, after obtaining the packing weight information, within a preset weight range, when the packing weight is small, the operating frequency of the tobacco feeding module is controlled to be high to quickly transport the expanded tobacco to the tobacco box, improving the packing efficiency. When the packing weight is large, the operating frequency of the tobacco feeding module is controlled to be slowed down to slow down the transport of the expanded tobacco to the tobacco box, allowing the expanded tobacco to be loaded into the tobacco box slowly and preventing the tobacco box from overflowing.

[0030] The preset weight range can be understood as a weight threshold range preset within the control module. For example, the preset weight range includes, but is not limited to, 0-12.0Kg. This embodiment of the invention does not impose any restrictions on this.

[0031] The expanded tobacco packing control method provided in this invention controls the operating frequency within a preset weight range to be negatively correlated with the packing weight information. This setting allows for high-frequency feeding of the expanded tobacco when the packing weight is low, enabling rapid packing, shortening empty box filling time, improving packing efficiency, and adapting to the production needs of large-volume expanded tobacco packing. When the box is nearly full, low-flow packing is performed to avoid a large amount of expanded tobacco falling into the box instantaneously, causing overflow and reducing tobacco loss. This improves the accuracy of packing weight control, achieving the goal of reducing material loss and equipment impact while ensuring packing efficiency.

[0032] Optionally, within a preset weight range, the operating frequency can be controlled to be negatively correlated with the packing weight information, including: When the packing weight is greater than the first preset weight and less than or equal to the second preset weight, the wire feeding module is controlled to operate at the first operating frequency; the second preset weight is greater than the first preset weight.

[0033] Specifically, the control module divides the preset weight range into multiple preset weight intervals. It precisely controls the operating frequency of the tobacco feeding module based on different preset weight intervals, and accurately adjusts the operating frequency of the tobacco feeding module according to the different loading amounts of expanded tobacco in the tobacco box. A first preset weight and a second preset weight are set within the preset weight range, and the acquired box weight information is compared with the first and second preset weights. When the control module determines that the current box weight is greater than the first preset weight and less than or equal to the second preset weight, it controls the tobacco feeding module to operate at the first operating frequency.

[0034] The first preset weight and the second preset weight can be understood as two different weight thresholds set in the control module according to a preset weight range, where the second preset weight is greater than the first preset weight. For example, the preset weight range is 0-12kg, the first preset weight is 10kg, and the second preset weight is 11.5kg; this embodiment of the invention does not impose any limitations on this. The first operating frequency can be understood as the operating frequency of the wire feeding module when the packing weight is greater than the first preset weight and less than or equal to the second preset weight.

[0035] When the packing weight is greater than the second preset weight and less than or equal to the third preset weight, the wire feeding module is controlled to operate at the second operating frequency; the third preset weight is greater than the second preset weight, and both the first and second preset weights are within the preset weight range; the second operating frequency is less than the first operating frequency.

[0036] Specifically, when the control module determines that the packing weight is greater than a second preset weight and less than or equal to a third preset weight, it controls the wire feeding module to operate at a second operating frequency. The third preset weight can be understood as a weight threshold set in the control module according to a preset weight range, and the third preset weight is greater than the second preset weight. For example, the third preset weight can be 12 kg, but this embodiment of the invention does not impose a limitation on this. The second operating frequency can be understood as the operating frequency of the wire feeding module when the packing weight is greater than the second preset weight and less than or equal to the third preset weight, and the second operating frequency is less than the first operating frequency. For example, the first operating frequency can be 40 Hz, and the second operating frequency can be 20 Hz.

[0037] It should be noted that the first and second preset weights are both within the preset weight range, and the third preset weight can be the boundary of the preset weight range.

[0038] For example, the control module sets a preset weight range of 0-12kg, with a first preset weight of 10kg, a second preset weight of 11.5kg, and a third preset weight of 12kg. When the control module receives a packing weight of 11kg, it controls the tobacco feeding module to deliver expanded tobacco to the tobacco box at a first operating frequency of 40Hz. When the control module receives a packing weight of 11.7kg, it controls the tobacco feeding module to deliver expanded tobacco to the tobacco box at a second operating frequency of 20Hz.

[0039] Optionally, when the packing weight is greater than a first preset weight and less than or equal to a second preset weight, the wire feeding module is controlled to operate at a first operating frequency, including: When the packing weight information is greater than the first preset weight and less than or equal to the second preset weight, the first operating frequency is determined according to the following correspondence and the wire feeding module is controlled to operate at the first operating frequency. F1 = A1 - (W - B1) × a1; Wherein, F1 is the first operating frequency, A1 is the first preset frequency coefficient, W is the packing weight information, B1 is the first preset weight coefficient, and a1 is the first correction coefficient.

[0040] Specifically, when the packing weight information is greater than the first preset weight and less than or equal to the second preset weight, the first operating frequency and the packing weight information satisfy the relationship F1 = A1 - (W - B1) × a1. The first operating frequency F1 is determined based on the first preset frequency coefficient A1, the packing weight information W, the first preset weight coefficient B1, and the first correction coefficient a1, so that the control module controls the wire feeding and conveying module to operate at the first operating frequency. Here, the first preset frequency coefficient A1, the first preset weight coefficient B1, and the first correction coefficient a1 are all parameters preset in the control module.

[0041] When the packing weight is greater than the second preset weight and less than or equal to the third preset weight, the wire feeding module is controlled to operate at the second operating frequency, including: When the packing weight information is greater than the second preset weight and less than or equal to the third preset weight, the second operating frequency is determined according to the following correspondence and the wire feeding module is controlled to operate at the second operating frequency. F2 = A2 - (W - B2) × a2; Where F2 is the second operating frequency, A2 is the second preset frequency coefficient, W is the packing weight information, B2 is the second preset weight coefficient, and a2 is the second correction coefficient; and A1 > A2, B1 < B2, and a1 < a2.

[0042] Specifically, when the packing weight information is greater than the second preset weight and less than or equal to the third preset weight, the second operating frequency and the packing weight information satisfy the relationship F2 = A2 - (W - B2) × a2. The second operating frequency F2 is determined based on the second preset frequency coefficient A2, the packing weight information W, the second preset weight coefficient B2, and the second correction coefficient a2, so that the control module controls the wire feeding conveyor module to operate at the second operating frequency. Here, the second preset frequency coefficient A2, the second preset weight coefficient B2, and the second correction coefficient a2 are all parameters preset in the control module.

[0043] It should be noted that the first preset frequency coefficient A1 is greater than the second preset frequency coefficient A2, the first preset weight coefficient B1 is less than the second preset weight coefficient B2, and the first correction coefficient a1 is less than the second correction coefficient a2.

[0044] For example, the first preset weight is set to 10kg, the second preset weight is set to 11.5kg, and the third preset weight is set to 12kg. The first preset frequency coefficient A1 is set to 50, the first preset weight coefficient B1 is set to 10, and the first correction coefficient a1 is set to 20. The second preset frequency coefficient A2 is set to 20, the second preset weight coefficient B2 is set to 11.5kg, and the second correction coefficient a2 is set to 40. When the control module obtains the packing weight information W as 11.5kg, the first operating frequency F1 is: F1=A1-(W-B1)×a1=50-(11.5-10)×20=40Hz; The control module then controls the wire feeding and conveying module to operate at a frequency of 40Hz.

[0045] When the control module obtains the packing weight information W as 11.7kg, the second operating frequency F2 is: F2=A2-(W-B2)×a2=20-(11.7-11.5)×40=12Hz; The control module then controls the wire feeding and conveying module to operate at a frequency of 12Hz.

[0046] Optionally, the operating frequency of the wire feeding module can be controlled based on the packing weight information, including: When the packing weight information is less than or equal to the first preset weight, the wire feeding module is controlled to operate at a fixed operating frequency; wherein the fixed operating frequency is greater than the first operating frequency.

[0047] Specifically, when the control module confirms that the received packing weight information is less than or equal to the first preset weight, it indicates that there is ample space in the tobacco box for loading expanded tobacco shreds. The control module then controls the tobacco feeding module to operate at a fixed frequency. This fixed frequency can be understood as the constant operating frequency of the tobacco feeding module throughout the entire range where the packing weight information is less than or equal to the first preset weight. The control module does not automatically adjust the frequency of the tobacco feeding module due to changes in on-site operating conditions. The fixed operating frequency is greater than the first operating frequency. For example, the fixed operating frequency can be 50Hz, and the first operating frequency can be 40Hz; this embodiment of the invention does not impose any limitations on this.

[0048] When the packing weight exceeds the third preset weight, the wire feeding module is stopped.

[0049] Specifically, when the control module confirms that the received packing weight information is greater than the third preset weight, it indicates that the expanded tobacco in the tobacco box is already fully loaded. The control module then controls the operating frequency of the tobacco supply and conveying module to be reduced to 0, and controls the tobacco supply and conveying module to stop operating, so as to prevent the expanded tobacco from continuing to be transported and loaded into the tobacco box, which would cause the expanded tobacco to overflow and spill, resulting in a large loss of expanded tobacco.

[0050] For example, the first preset weight is set to 10kg, the second preset weight is set to 11.5kg, and the third preset weight is set to 12kg. When the control module receives a packing weight of 5kg, it can control the wire feeding conveyor module to operate at a fixed frequency of 50Hz. When the control module receives a packing weight of 11.5kg, it can control the wire feeding conveyor module to operate at a first operating frequency of 40Hz. When the control module receives a packing weight of 13kg, it controls the wire feeding conveyor module to stop operating.

[0051] The expanded tobacco packing control method provided in this invention divides a preset weight range into a first preset weight, a second preset weight, and a third preset weight. The operating frequency of the tobacco feeding module is determined based on the relationship between the actual acquired packing weight information and the first, second, and third preset weights. The tobacco feeding module is then controlled to operate at different operating frequencies within different preset weight ranges. When the packing weight information is greater than the first preset weight and less than or equal to the second preset weight, the tobacco feeding module is controlled to operate at the first operating frequency. When the packing weight information is greater than the second preset weight and less than or equal to the third preset weight, the tobacco feeding module is controlled to operate at the second operating frequency. When the packing weight information is less than or equal to the first preset weight, the tobacco feeding module is controlled to operate at a fixed operating frequency. When the packing weight information is greater than the third preset weight, the tobacco feeding module is controlled to stop operating. By adopting the above technical solution, the operating frequency of the tobacco feeding and conveying module is adjusted in stages and levels, achieving efficient packing in the early stage and precise control of packing weight through gradual speed reduction in the middle and later stages. This improves packing efficiency while controlling the packing weight accuracy, preventing the expanded tobacco from overflowing from the box. It also enhances the flexibility of adjusting the operating frequency of the tobacco feeding and conveying module, solving the problem that single-stage speed adjustment cannot simultaneously meet efficiency and accuracy control. Furthermore, the operating frequency of the tobacco feeding and conveying module is determined based on preset frequency coefficients, packing weight information, preset weight coefficients, and correction coefficients, achieving adaptive adjustment of the tobacco feeding speed according to the packing weight. Control parameters can be flexibly optimized through coefficients, ensuring the accuracy of determining the operating frequency of the tobacco feeding and conveying module, improving the control precision of expanded tobacco packing, and solving the problems of high material loss and low conveying efficiency caused by poor precision control in manual packing.

[0052] Figure 2 This is a flowchart of another method for controlling the packing of expanded tobacco provided by an embodiment of the present invention. The embodiment of the present invention elaborates in detail the specific control method for controlling the operating frequency of the tobacco supply conveying module based on the packing weight information in any of the above optional embodiments of the method for controlling the packing of expanded tobacco. The tobacco supply conveying module includes a first conveying unit, and the control module is electrically connected to the first conveying unit. The first conveying unit is used to transport expanded tobacco to the tobacco box to be loaded. Figure 2 As shown, the method specifically includes: S210. Obtain the packing weight information of expanded tobacco.

[0053] S220. Control the operating frequency of the first conveying unit according to the packing weight information.

[0054] Specifically, the tobacco feeding and conveying module includes a first conveying unit, which can be understood as a conveying mechanism on the side of the tobacco feeding and conveying module near the tobacco box to be loaded. The first conveying unit includes, but is not limited to, a conveyor belt, and this embodiment of the invention does not impose any limitations on this. Expanded tobacco is directly conveyed from the first conveying unit to the tobacco box to be loaded.

[0055] The control module is electrically connected to the first conveying unit. After acquiring the packing weight information of the expanded tobacco, it sets the operating frequency of the first conveying unit based on the packing weight information. The first conveying unit continuously feeds the expanded tobacco according to the operating frequency. Within a preset weight range, when the control module determines that the received packing weight information is small, it controls the operating frequency of the first conveying unit to be fast, so as to quickly transport the expanded tobacco to the tobacco box and improve the packing efficiency of the expanded tobacco. When the control module determines that the received packing weight information is large, it controls the operating frequency of the first conveying unit to be slowed down, slowing down the transport of the expanded tobacco to the tobacco box, so that the expanded tobacco is slowly loaded into the tobacco box and avoids the tobacco box from overflowing.

[0056] The expanded tobacco packing control method provided in this invention, after acquiring the packing weight information of the expanded tobacco, controls the operating frequency of the first conveying unit based on the packing weight information. This achieves precise control of the operating frequency of the first conveying unit, which directly feeds the tobacco into the tobacco feeding module. It precisely regulates the packing speed of the expanded tobacco from the feeding end, shortens the control response chain, improves the response speed of the first conveying unit, reduces control lag, and increases packing efficiency. Simultaneously, it simplifies the overall structure of the packing device. This avoids the problems of low packing efficiency and large packing device size caused by long control chains and large response lags.

[0057] Figure 3 This is a flowchart of another packaging control method for expanded tobacco provided in this embodiment of the invention. This embodiment of the invention provides a detailed description of another packaging control method. For example... Figure 3 As shown, the packing control method also includes: S310. Obtain the height information of the expanded tobacco in the second conveying unit.

[0058] Specifically, the tobacco feeding and conveying module includes a first conveying unit and a second conveying unit. The first conveying unit can be understood as the conveying mechanism of the tobacco feeding and conveying module near the tobacco box to be loaded, and the second conveying unit can be understood as the conveying mechanism of the tobacco feeding and conveying module connected to the first conveying unit for conveying expanded tobacco to the first conveying unit. The second conveying unit includes, but is not limited to, a conveyor belt; this embodiment of the invention does not impose any limitations on this.

[0059] The control module is electrically connected to both the first and second conveying units. The second conveying unit transports expanded tobacco shreds to the first conveying unit, which in turn transports the expanded tobacco shreds to the tobacco box to be loaded. The second conveying unit is equipped with a material height detection module. This module can be understood as a height detection module used to collect real-time information on the height of accumulated material levels and feed it back to the control module. For example, the material height detection module may include, but is not limited to, an ultrasonic material level height detection sensor; this embodiment of the invention does not impose any limitations on this.

[0060] During the process of conveying expanded tobacco shreds from the second conveying unit to the first conveying unit, the material height detection module detects the height information of the expanded tobacco shreds in the second conveying unit. The material height detection module is electrically connected to the control module and transmits the collected height information of the expanded tobacco shreds to the control module. The control module then obtains the height information of the expanded tobacco shreds in the second conveying unit.

[0061] S320. Control the operating frequency of the second transmission unit based on the altitude information.

[0062] Specifically, after acquiring the height information of the expanded tobacco, the control module controls the operating frequency of the second conveying unit based on this information. The control module has a preset height threshold. When the control module determines that the height information is less than the preset height threshold, it increases the operating frequency of the second conveying unit to speed up the delivery of the expanded tobacco and ensure continuous supply. When the control module determines that the height information is greater than or equal to the preset height threshold, it indicates that there is too much expanded tobacco piled up and needs to be packed before being delivered to the first conveying unit. In this case, the control module reduces the operating frequency of the second conveying unit, decreasing the speed at which it delivers the expanded tobacco to the first conveying unit or stopping the second conveying unit altogether. When the height information is less than the preset height threshold, the control module restarts the second conveying unit.

[0063] The packing control method for expanded tobacco provided in this invention obtains the height information of the expanded tobacco in the second conveying unit and then controls the operating frequency of the second conveying unit based on the height information. By adopting this technical solution, the feeding of tobacco by the second conveying unit is adaptively adjusted, ensuring the continuity of tobacco feeding to the first conveying unit and the uniformity of the expanded tobacco packing, improving the automation level of the packing device and reducing manual control. This solves the problems of raw material waste caused by the accumulation and overflow of expanded tobacco due to the inability of the second conveying unit's operating frequency to adaptively adjust according to the height information of the expanded tobacco, low packing efficiency caused by insufficient feeding continuity when there is a shortage of expanded tobacco, and low efficiency and poor control accuracy of manual control.

[0064] Figure 4This is a flowchart of another method for controlling the packing of expanded tobacco provided by an embodiment of the present invention. This embodiment of the present invention provides a detailed description of another control method after obtaining the packing weight information of the expanded tobacco in the above optional embodiments. The packing device further includes a tobacco box conveying module and a first positioning detection module, and the control module is electrically connected to both the tobacco box conveying module and the first positioning detection module. Figure 4 As shown, the method specifically includes: S410. Obtain the packing weight information of expanded tobacco.

[0065] S420. After confirming that the cigarette box is full, transport the fully loaded cigarette box and obtain the arrival information of the fully loaded cigarette box.

[0066] Specifically, the packing device includes a cigarette box conveying module and a first-position detection module. The cigarette box conveying module can be understood as a transport structure capable of transporting empty cigarette boxes to the discharge port, carrying the cigarette boxes during the filling process, and transporting the fully loaded cigarette boxes out after packing. The cigarette box conveying module includes, but is not limited to, a cigarette box conveyor roller conveyor. The first-position detection module can be understood as a detection function module used to detect the position signal of the target object reaching a designated position and provide position signal feedback. The first-position detection module includes, but is not limited to, photoelectric sensors; this embodiment of the invention does not impose limitations on this.

[0067] When the control module determines that the received packing weight information is greater than the third preset weight, it determines that the cigarette box is fully loaded. The control module is electrically connected to the cigarette box conveying module and controls the cigarette box conveying module to transport the fully loaded cigarette box away from the discharge port of the tobacco supply conveying module. The first arrival detection module is set in the fully loaded cigarette box storage area to detect the arrival information of the fully loaded cigarette box. The first arrival detection module is electrically connected to the control module and transmits the detected arrival information of the fully loaded cigarette box to the control module, and the control module obtains the arrival information of the fully loaded cigarette box.

[0068] S430: Measure the number of fully loaded tobacco boxes according to the arrival information, and control the tobacco box conveying module to transport the tobacco boxes to be loaded to the discharge port of the tobacco supply conveying module according to the arrival information.

[0069] Specifically, after receiving information about the arrival of fully loaded tobacco boxes, the control module counts the number of fully loaded tobacco boxes based on the number of times this information is received. Each time the control module receives information about the arrival of a fully loaded tobacco box, it counts the number of boxes. By accumulating this information, the number of fully loaded tobacco boxes can be counted, facilitating the staff's statistics on the packing data of expanded tobacco.

[0070] Meanwhile, after the control module obtains the arrival information of the fully loaded tobacco box, it confirms that the fully loaded tobacco box has left the discharge port of the tobacco feeding conveyor module. Then, it controls the tobacco box conveying module to continue to transport the tobacco box to be loaded to the discharge port of the tobacco feeding conveyor module for the next step of packing expanded tobacco.

[0071] The expanded tobacco packing control method provided in this invention obtains the packing weight information of the expanded tobacco, transports the fully loaded tobacco box after determining it is full based on the packing weight information, and obtains the arrival information of the fully loaded tobacco box. Then, it measures the number of fully loaded tobacco boxes based on the arrival information and controls the tobacco box conveying module to transport the tobacco boxes to be loaded to the discharge port of the tobacco feeding conveying module based on the arrival information. This setup determines the transport of fully loaded tobacco boxes based on the full load weight, and the full box arrival signal takes into account both counting and empty box replenishment, realizing automated closed-loop control of the transfer of fully loaded tobacco boxes, quantity statistics, and empty box loading. This ensures packing continuity and accuracy, reduces spillage loss of expanded tobacco, and improves production safety and the efficiency of expanded tobacco packing operations. It can accurately count the number of boxes produced without adding detection equipment, simplifying the device structure while improving data statistics efficiency and accuracy. It solves the problems of low efficiency, high safety hazards, and low data statistics accuracy of manual operation.

[0072] Figure 5 This is a flowchart of another method for controlling the packing of expanded tobacco shreds according to an embodiment of the present invention. The embodiment of the present invention elaborates in detail the steps following the control of the tobacco box conveying module to transport the tobacco box to be loaded to the discharge port of the tobacco supply conveying module based on the arrival information. For example... Figure 5 As shown, the method specifically includes: S510. Obtain the packing weight information of expanded tobacco.

[0073] S520. After confirming that the cigarette box is full, transport the fully loaded cigarette box and obtain the arrival information of the fully loaded cigarette box.

[0074] S530: Measure the number of fully loaded tobacco boxes according to the arrival information, and control the tobacco box conveying module to transport the tobacco boxes to be loaded to the discharge port of the tobacco supply conveying module according to the arrival information.

[0075] S540: Obtain the arrival information of the cigarette box to be loaded.

[0076] Specifically, the packing device also includes a second positioning detection module. The second positioning detection module can be understood as a detection module that can detect the position information of the cigarette box to be loaded and feed back the position information to the control module. For example, the second positioning detection module includes, but is not limited to, photoelectric sensors. This embodiment of the invention does not limit this.

[0077] The control module is electrically connected to the second positioning detection module, which is located below the discharge port of the wire feeding conveyor module. When the control module controls the tobacco box conveyor module to transport the tobacco box to be loaded to the discharge port of the wire feeding conveyor module according to the positioning information, the second positioning detection module detects the positioning information of the tobacco box to be loaded and transmits the positioning information of the tobacco box to be loaded to the control module. The control module receives the positioning information of the loaded tobacco box to determine whether the tobacco box to be loaded has reached the position of the discharge port of the wire feeding conveyor module.

[0078] S550 controls the start and stop of the filament feeding and conveying module based on the arrival information of the cigarette box to be loaded.

[0079] After receiving the arrival information of the tobacco box to be loaded, the control module determines whether the tobacco box has reached the discharge port of the tobacco feeding conveyor module. When the control module determines that the tobacco box has reached the discharge port of the tobacco feeding conveyor module based on the arrival information, it controls the tobacco feeding conveyor module to start discharging, ensuring that the expanded tobacco is accurately loaded into the tobacco box. When the control module does not receive the arrival information of the tobacco box, it controls the tobacco feeding conveyor module not to start discharging, and at the same time, the control module issues an alarm prompt to facilitate timely inspection by the staff.

[0080] The expanded tobacco packing control method provided in this invention involves controlling the tobacco box conveying module to transport the tobacco box to be loaded to the discharge port of the tobacco feeding conveying module based on the arrival information, obtaining the arrival information of the tobacco box to be loaded, and controlling the start and stop of the discharge of the tobacco feeding conveying module based on the arrival information of the tobacco box to be loaded. By adopting the above technical solution, the arrival of the tobacco feeding and the box to be loaded is jointly controlled, ensuring the continuity of packing, avoiding the phenomenon of unloaded tobacco without a box, reducing the loss caused by spillage of expanded tobacco, and reducing the frequency of cleaning at the work site and the safety hazards of operation.

[0081] Based on the same inventive concept, embodiments of the present invention also provide a packaging device for expanded tobacco shreds. Figure 6 This is a schematic diagram of a packing device for expanded tobacco provided in an embodiment of the present invention. Figure 7 This is a schematic diagram of another packaging device for expanded tobacco provided in an embodiment of the present invention. Figure 8 This is a schematic diagram of another packaging device for expanded tobacco provided in an embodiment of the present invention. Figure 9 This is a schematic diagram of another packaging device for expanded tobacco provided in an embodiment of the present invention. The packaging device for expanded tobacco provided in this embodiment of the present invention is used to execute the packaging control method for expanded tobacco provided in any of the above optional embodiments. Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the packing device for expanded tobacco includes a tobacco feeding and conveying module 10, a weight detection module 20, and a control module 30. The tobacco feeding and conveying module 10 is used to convey expanded tobacco to the tobacco box 1 to be loaded. The weight detection module 20 is used to detect the packing weight information of the expanded tobacco. The control module 30 is electrically connected to the weight detection module 20 and the tobacco feeding and conveying module 10 respectively, and is used to obtain the packing weight information of the expanded tobacco and control the operating frequency of the tobacco feeding and conveying module 10 according to the packing weight information.

[0082] In this embodiment, the packing device for expanded tobacco shreds includes a shred feeding and conveying module 10, a weight detection module 20, and a control module 30. The shred feeding and conveying module 10 can be understood as a conveying mechanism that, driven by a drive mechanism, transports shredded material along a preset pipeline in a directional manner, achieving continuous, quantitative, and stable material transport. The weight detection module 20 can be understood as a weighing component capable of acquiring real-time weight signals of the material being measured, converting and processing them through circuitry, and then outputting the acquired weight signals. For example, the weight detection module 20 may include, but is not limited to, a weight sensor; this embodiment of the invention does not impose limitations on this. The control module 30 is a functional module capable of receiving instructions, acquiring signals, processing data, and outputting control signals to drive actuators to complete preset actions. The control module 30 may include, but is not limited to, a computer.

[0083] Specifically, the tobacco feeding and conveying module 10 includes a first conveying unit 11, a second conveying unit 12, and a third conveying unit 13. The first conveying unit 11, the second conveying unit 12, and the third conveying unit 13 are arranged sequentially in the direction close to the tobacco box 1 to be loaded. The first conveying unit 11, the second conveying unit 12, and the third conveying unit 13 include, but are not limited to, a conveyor belt. This embodiment of the invention does not impose any restrictions on this.

[0084] The first conveying unit 11 is located near the tobacco box 1 to be loaded and is used to convey expanded tobacco to the tobacco box 1. The second conveying unit 12 is electrically connected to the first conveying unit 11 and is used to convey expanded tobacco to the first conveying unit 11. The third conveying unit 13 is electrically connected to the second conveying unit 12 and is used to receive the expanded tobacco conveyed by the equipment and transport the expanded tobacco to the second conveying unit 12. The weight detection module 20 is electrically connected to the control module 30. After the expanded tobacco is loaded into the tobacco box, the weight detection module measures the current weight information of the expanded tobacco in real time and transmits the weight information to the control module 30.

[0085] The control module 30 is electrically connected to the weight detection module 20 and the tobacco feeding and conveying module 10, respectively. After acquiring the packing weight information, it sets the operating frequency of the tobacco feeding and conveying module 10 according to the packing weight information. The tobacco feeding and conveying module 10 then feeds the expanded tobacco according to the operating frequency. The control module 30 adjusts the operating frequency of the tobacco feeding and conveying module 10 according to the real-time packing weight information, realizing graded control of fast feeding, slow feeding, micro-feeding, and stopping feeding. This ensures that the expanded tobacco fed by the tobacco feeding and conveying module 10 is efficiently delivered to the tobacco box 1 to be loaded, avoiding overfilling and overflowing while improving the packing efficiency of the expanded tobacco.

[0086] Furthermore, after acquiring the packing weight information of the expanded tobacco, the control module 30 can set the operating frequency of the first conveying unit 11 based on the packing weight information. The first conveying unit 11 continuously feeds the expanded tobacco according to the operating frequency. Within a preset weight range, when the control module 30 determines that the received packing weight information is small, it controls the operating frequency of the first conveying unit 11 to be fast, so as to quickly transport the expanded tobacco to the tobacco box and improve the packing efficiency of the expanded tobacco. When the control module 30 determines that the received packing weight information is large, it controls the operating frequency of the first conveying unit 11 to be slowed down, slowing down the transport of the expanded tobacco to the tobacco box, so that the expanded tobacco is slowly loaded into the tobacco box and avoids the tobacco box from overflowing.

[0087] Specifically, the packing device also includes a cigarette box conveying module 40 and a first positioning detection module (not shown in the figure). The cigarette box conveying module 40 can be understood as a transport structure capable of transporting empty cigarette boxes to the discharge port, carrying the cigarette boxes during the filling process, and transporting the fully loaded cigarette boxes 2 out after packing. The cigarette box conveying module 40 includes, but is not limited to, a cigarette box conveying roller conveyor. The first positioning detection module can be understood as a detection function module used to detect the position signal of the target object reaching a designated position and to provide position signal feedback. The first positioning detection module includes, but is not limited to, photoelectric sensors; this embodiment of the invention does not impose limitations on this. The control module 30 is electrically connected to both the cigarette box conveying module 40 and the first positioning detection module.

[0088] Once the control module 30 determines that the tobacco box is full, it controls the tobacco box conveying module 40 to transport the full-loaded tobacco box 2 away from the discharge port of the tobacco supply conveying module 10. A first arrival detection module is located in the storage area of ​​the full-loaded tobacco box 2 to detect the arrival information of the full-loaded tobacco box 2 and transmits this information to the control module 30. After the control module 30 obtains the arrival information of the full-loaded tobacco box 2, it confirms that the full-loaded tobacco box 2 has left the discharge port position of the tobacco supply conveying module 10. Then, it controls the tobacco box conveying module 40 to continue conveying the tobacco box 1 to be loaded to the discharge port of the tobacco supply conveying module 10 for the next sequence of expanding tobacco packing.

[0089] The expanded tobacco packing device provided in this embodiment of the invention is used to execute a packing control method for expanded tobacco. By setting up a tobacco feeding and conveying module 10, a weight detection module 20, and a control module 30 in the packing device, the tobacco feeding and conveying module 10 transports expanded tobacco to the tobacco box 1 to be loaded. The weight detection module 20 detects the packing weight information of the expanded tobacco. The control module 30 is electrically connected to both the weight detection module 20 and the tobacco feeding and conveying module 10 to obtain the packing weight information and control the operating frequency of the tobacco feeding and conveying module 10 based on the packing weight information. With this setup, the packing device automatically adjusts the operating frequency of the tobacco feeding and conveying module 10 according to the packing weight information, achieving automated and precise packing of expanded tobacco. The integrated design of tobacco feeding, weighing, and packing improves the intelligence level of the tobacco production logistics process, reduces manual labor intensity, reduces packing weight deviation and raw material loss, and ensures the safety of the expanded tobacco packing operation. It solves the problems of low automation, low efficiency, poor weighing accuracy, difficulty in standardizing on-site operations, and prominent safety hazards in the manual processes of feeding, weighing, and packing of expanded tobacco.
