Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Figure 1 This is a schematic diagram of the structure of the tobacco supply system implementing an embodiment of the present invention. Figure 1 As shown, the tobacco supply system includes a tobacco feeder, a pneumatic tobacco feeding device, and a cigarette making machine. The tobacco feeder includes a tobacco-pulling roller, a longitudinal conveyor belt, and a transverse conveyor belt, all of which can adjust the tobacco feeding flow rate by adjusting the frequency of a frequency converter.

[0031] Example 1
[0032] Figure 2 This is a flowchart of a tobacco feeding flow control method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where the method can be executed by a tobacco feeding flow control device, which can be implemented in hardware and / or software, and can be configured in a tobacco supply system. For example... Figure 2 As shown, the method includes:
[0033] S210. Obtain the basic configuration information of the tobacco supply system.
[0034] Among them, the basic configuration information refers to the basic configuration information of each operating device or component in the tobacco supply system. Specifically, the basic configuration information includes the basic wind speed of the wind-powered tobacco feeding device, the basic speed of the cigarette machine, and the basic operating frequency of the tobacco feeding machine conveyor belt.
[0035] In this embodiment, the basic wind speed of the wind-powered feeding device, the basic speed of the cigarette machine, and the basic operating frequency of the feeder conveyor belt in the tobacco supply system are obtained.
[0036] S220. Detect the current wind speed of the wind-powered feeding device and the current vehicle speed of the cigarette machine; determine the target operating frequency of the conveyor belt based on the current wind speed, the current vehicle speed and the basic configuration information.
[0037] In this embodiment, the current wind speed of the wind-powered feeding device and the current speed of the cigarette machine can be collected in real time or at regular intervals. The interval can be set by those skilled in the art based on experience and needs, and is not limited here. For example, the current wind speed of the wind-powered feeding device and the current speed of the cigarette machine can be collected every 1 second by a programmable logic controller (PLC).
[0038] The target operating frequency refers to the operating frequency of the frequency converter of the feeder conveyor belt adapted to the current wind speed of the pneumatic feeding device and the current speed of the cigarette machine. In essence, the conveyor belt is driven by a frequency converter, and the operating frequency of the frequency converter is the operating frequency of the conveyor belt. In this embodiment, a correlation equation is established between the target operating frequency of the conveyor belt and the current wind speed of the pneumatic feeding device, the current speed of the cigarette machine, and basic configuration information. The target operating frequency of the conveyor belt is determined based on the correlation equation, the current wind speed of the pneumatic feeding device, and the current speed of the cigarette machine.
[0039] Based on the above embodiments, optionally, the conveyor belt includes a transverse conveyor belt and a longitudinal conveyor belt; correspondingly, the basic operating frequency includes the transverse basic operating frequency of the transverse conveyor belt and the longitudinal basic operating frequency of the longitudinal conveyor belt, and the target operating frequency includes the transverse operating frequency of the transverse conveyor belt and the longitudinal operating frequency of the longitudinal conveyor belt; determining the target operating frequency of the conveyor belt based on the current wind speed, the current vehicle speed, and the basic configuration information includes: determining the transverse operating frequency based on the transverse basic operating frequency, the current wind speed, the basic wind speed, the current vehicle speed, and the basic vehicle speed; and determining the longitudinal operating frequency based on the longitudinal basic operating frequency and the transverse operating frequency.
[0040] like Figure 1 As shown, the conveyor belt of the tobacco feeder includes a transverse conveyor belt and a longitudinal conveyor belt. The finished tobacco shreds are first conveyed by the longitudinal conveyor belt to the transverse conveyor belt, and then by the transverse conveyor belt to the hopper. Correspondingly, the basic operating frequency includes the transverse basic operating frequency of the transverse conveyor belt and the longitudinal basic operating frequency of the longitudinal conveyor belt, and the target operating frequency includes the transverse operating frequency of the transverse conveyor belt and the longitudinal operating frequency of the longitudinal conveyor belt. In this embodiment, the correlation equations include the correlation equations for the transverse operating frequency and the longitudinal operating frequency. The correlation equation for the transverse operating frequency is constructed from the relationship between the transverse operating frequency and the transverse basic operating frequency, the current wind speed of the pneumatic tobacco feeding device, the base wind speed of the pneumatic tobacco feeding device, the current speed of the cigarette machine, and the base speed of the cigarette machine. The transverse operating frequency can be calculated based on the correlation equation for the transverse operating frequency, the current wind speed of the pneumatic tobacco feeding device, and the current speed of the cigarette machine. The correlation equation for the longitudinal operating frequency is constructed from the relationship between the longitudinal operating frequency, the longitudinal basic operating frequency, and the transverse operating frequency. The longitudinal operating frequency can be calculated based on the correlation equation for the longitudinal operating frequency, the longitudinal basic operating frequency, and the transverse operating frequency.
[0041] Based on the above embodiments, optionally, determining the lateral operating frequency based on the lateral base operating frequency, the current wind speed, the base wind speed, the current vehicle speed, and the base vehicle speed includes: obtaining a first compensation coefficient and a second compensation coefficient; determining the vehicle speed change based on the current vehicle speed and the base vehicle speed, and determining a first compensation amount based on the first compensation coefficient and the vehicle speed change; determining the wind speed change based on the current wind speed and the base wind speed, and determining a second compensation amount based on the second compensation coefficient and the wind speed change; and determining the lateral operating frequency based on the lateral base operating frequency, the first compensation amount, and the second compensation amount.
[0042] In this embodiment, the first compensation coefficient refers to the speed compensation coefficient of the cigarette rolling machine, and the second compensation coefficient refers to the wind speed compensation coefficient of the pneumatic feeding device. The speed change can be determined based on the current speed and the base speed of the cigarette rolling machine, and then the first compensation amount can be determined based on the speed change and the first compensation coefficient. Similarly, the wind speed change can be determined based on the current wind speed and the base wind speed of the pneumatic feeding device, and then the second compensation amount can be determined based on the wind speed change and the second compensation coefficient. The lateral operating frequency is determined based on the lateral base operating speed, the first compensation amount, and the second compensation amount.
[0043] For example, the correlation equation for the lateral running frequency is as follows:
[0044] F1 = F 1基 +K1*(V 车 -V 车基 )+K2*(V 风 -V 风基 )
[0045] Where F1 represents the lateral operating frequency, F 1基 V represents the horizontal foundation operating frequency. 车 This indicates the current speed of the cigarette rolling machine, K1 is the first compensation coefficient, and V... 车基 This represents the base speed of the cigarette rolling machine, K2 is the second compensation coefficient, and V... 风 V represents the current wind speed of the wind-powered wire feeding device. 风基 This represents the base wind speed of the wind-powered wire feeding device, (V) 车 -V 车基 ) represents the change in vehicle speed, K1*(V 车 -V 车基 (V) is the first compensation amount. 风 -V 风基 Wind speed change, K2*(V) 风 -V 风基 ) is the second compensation amount.
[0046] Based on the above embodiments, optionally, the lateral operating frequency is positively correlated with the first compensation amount, and the lateral operating frequency is negatively correlated with the second compensation amount.
[0047] In this embodiment, the lateral operating frequency is positively correlated with the first compensation amount. That is, the greater the change in vehicle speed, i.e., the higher the speed of the cigarette machine, the greater the lateral operating frequency, and the first compensation coefficient is positive. For example, it can be expressed as K1 > 0. The lateral operating frequency is negatively correlated with the second compensation amount. That is, the greater the change in wind speed, i.e., the higher the wind speed of the wind-powered feeding device, the greater the lateral operating frequency, and the second compensation coefficient is negative. For example, it can be expressed as K2 < 0.
[0048] Based on the above embodiments, optionally, determining the longitudinal operating frequency based on the longitudinal basic operating frequency and the lateral operating frequency includes: obtaining a third compensation coefficient; determining a third compensation amount based on the third compensation coefficient and the lateral operating frequency; and determining the longitudinal operating frequency based on the third compensation amount and the longitudinal basic operating frequency.
[0049] The third compensation coefficient refers to the lateral compensation coefficient. This means that the finished tobacco shreds are first conveyed by the longitudinal conveyor belt to the lateral conveyor belt, and then by the lateral conveyor belt to the hopper. When the lateral operating frequency changes, the longitudinal operating frequency needs to be changed accordingly. In this embodiment, the third compensation amount can be determined based on the lateral operating frequency and the third compensation coefficient, and then the longitudinal operating frequency can be determined based on the third compensation amount and the longitudinal base operating frequency.
[0050] For example, the longitudinal running frequency correlation equation is as follows:
[0051] F2 = F 2基 +K3*F1
[0052] Where F2 represents the longitudinal operating frequency, F 2基 K3 represents the longitudinal basic operating frequency, K3 is the third compensation coefficient, F1 represents the transverse operating frequency, and K3*F1 is the third compensation amount.
[0053] Based on the above embodiments, optionally, the basic configuration information further includes a high material level boundary value and a low material level boundary value; determining the longitudinal operating frequency based on the third compensation amount and the longitudinal basic operating frequency includes: detecting the feeding height of the transverse conveyor belt; if the feeding height is greater than or equal to the high material level boundary value, then determining a first longitudinal operating frequency based on the third compensation amount and the longitudinal basic operating frequency; the first longitudinal operating frequency is negatively correlated with the third compensation amount; if the feeding height is less than or equal to the low material level boundary value, then determining a second longitudinal operating frequency based on the third compensation amount and the longitudinal basic operating frequency; the second longitudinal operating frequency is positively correlated with the third compensation amount.
[0054] The basic configuration information also includes high and low material level boundary values. These boundary values represent the material level limits on the transverse conveyor belt of the wire feeder. When the feeding height reaches the high material level boundary value (i.e., the feeding height is greater than the high material level boundary value), the longitudinal operating frequency of the longitudinal conveyor belt needs to be reduced. Conversely, when the feeding height reaches the low material level boundary value (i.e., the feeding height is less than the low material level boundary value), the longitudinal operating frequency of the longitudinal conveyor belt needs to be increased. The high and low material level boundary values are set by those skilled in the art based on experience and requirements, and are not limited here. In this embodiment, the feeding height of the transverse conveyor belt can be detected by a grating. If the feeding height is greater than or equal to the high material level boundary value, the first longitudinal operating frequency can be determined based on the third transverse compensation amount and the longitudinal basic operating frequency. At this time, the first longitudinal operating frequency is negatively correlated with the third compensation amount, that is, the third compensation coefficient is negative, which can be represented as K3 < 0. If the feeding height is less than or equal to the low material level boundary value, the second longitudinal operating frequency can be determined based on the third compensation amount and the longitudinal basic operating frequency. At this time, the second longitudinal operating frequency is positively correlated with the third compensation amount, that is, the third compensation coefficient is positive, which can be represented as K3 > 0.
[0055] S230. Control the operation of the conveyor belt based on the target operating frequency to adjust the fiber feeding flow rate.
[0056] In this embodiment, the frequency of the longitudinal conveyor belt inverter is adjusted according to the longitudinal operating frequency to control the operation of the longitudinal conveyor belt, and the frequency of the transverse conveyor belt inverter is adjusted according to the transverse operating frequency to control the operation of the transverse conveyor belt, thereby adjusting the wire feeding flow rate.
[0057] The technical solution of this embodiment detects the current wind speed of the pneumatic feeding device and the current speed of the cigarette machine; determines the target operating frequency of the conveyor belt based on the current wind speed, current speed, and basic configuration information of the tobacco supply system; controls the operation of the conveyor belt based on the target operating frequency to adjust the tobacco feeding flow rate; achieves precise control of the tobacco feeding flow rate, solves the problem of unstable tobacco feeding flow rate in the tobacco supply system, effectively suppresses the fluctuation of tobacco feeding flow rate caused by changes in the speed of the cigarette machine and the wind force of the pneumatic feeding device, and improves the stability of the tobacco feeding flow rate.
