Description

Technical Field

[0001] This invention relates to the field of tobacco processing technology, and in particular to a method, apparatus, equipment and storage medium for controlling tobacco feeding. Background Technology

[0002] Tobacco additives are the process of evenly spraying a prepared tobacco "liquid" onto the raw tobacco. The ultimate goal of additives is to improve the smoking quality of cigarettes, creating a unique style to meet the needs of smokers.

[0003] A typical tobacco processing technology and equipment involves heating and humidifying tobacco raw materials such as tobacco leaves, stems, and granular stems before feeding them into a drum feeder. Inside the drum feeder, the tobacco is fed through atomizing nozzles. The rotating drum conveys and agitates the tobacco, ensuring a uniform mixture with the tobacco "liquid." After being balanced in a storage tank, the tobacco raw materials are then sent to a shredding machine for further processing. This processing technology and equipment are widely used worldwide. The core equipment of this process includes a drum flavoring machine and a tobacco flavoring application device. The tobacco "liquid" is quantitatively sprayed onto the tobacco leaves according to the requirements of different blends and tobacco materials.

[0004] Chinese patent application No. 201010227367.9 discloses a calibration method and apparatus for the metering accuracy of a flavoring / addition system. This method adjusts the operating frequency of the metering pump in the delivery pipeline of the flavoring / addition system using a proportional-integral-derivative (PID) control unit to fill the pipeline with fragrance / scent according to a preset flow rate. However, this method of regulating the addition flow rate by controlling the frequency of the metering pump through PID control is prone to uneven addition. Summary of the Invention

[0062] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0063] This invention provides a method for controlling tobacco feeding, such as... Figure 1 As shown, tobacco material is transported to a tobacco feeding device via an electronic belt scale 5 for liquid addition. The tobacco feeding device includes a feeder 1 and a storage tank 2, with the feeder 1 connected to the storage tank 2 via a connecting pipe 3. The tobacco feeding device also includes an actuator 4, which controls the flow rate of the liquid entering the feeder 1 by adjusting its execution parameters.

[0064] The inventors discovered that when tobacco is fed with liquid through a tobacco feeding device, a flow meter 6 is usually installed on the connecting pipe 3. The flow meter 6 is used to collect the flow rate of the liquid in the connecting pipe 3 and transmit it to the control unit. The control unit performs PID calculation based on the collected flow rate and outputs the feeding accuracy as the feedback value to the actuator 4. The actuator 4 controls its execution parameters based on the PID feedback result. However, for the feed head, the amount of liquid added to the feed head is based on the feeding accuracy as the feedback value. At this time, the feeding accuracy is not yet stable. If the feed head is adjusted by PID, uneven feeding often occurs.

[0065] like Figure 2 As shown, in one embodiment of the present invention, the tobacco feeding control method includes the following steps:

[0066] Step S101: Every first preset time interval, obtain the weight of the material weighed by the electronic belt scale 5 and the operating speed of the electronic belt scale 5 at that time;

[0067] Step S102: Obtain the feeding ratio of the liquid material;

[0068] Step S103: Based on the feeding ratio, the weight of each material, and the running speed of the electronic belt scale 5 corresponding to the weight of each material, obtain the liquid flow rate corresponding to the weight of each material.

[0069] Step S104: Obtain the relationship between the execution parameters and the flow rate of the liquid, and determine the execution parameters corresponding to each flow rate of the liquid based on the relationship.

[0070] By employing the above technical solution, the material weight and operating speed of the electronic belt scale 5 are obtained at each first preset time interval, thus acquiring the material weight and operating speed of the electronic belt scale 5 at each time point corresponding to the first preset time interval. Furthermore, by acquiring the feeding ratio of the liquid material and based on the obtained material weights and the corresponding operating speeds of the electronic belt scale 5, the corresponding liquid material flow rates are obtained for each material weight. Then, the execution parameters corresponding to each liquid material flow rate are determined using the relationship between the actuator's execution parameters and the liquid material flow rate. In this way, the liquid material flow rate is determined based on the material weight and the current operating speed of the electronic belt scale 5, allowing the liquid material flow rate to change with the material weight, thereby improving the uniformity of liquid material feeding and, in particular, avoiding uneven material distribution.

[0071] Specifically, in step S101, every first preset time T w Record the material weight W measured by the electronic belt scale 5, and record the operating speed V of the electronic belt scale 5 at this time. Send the recorded material weight W and its corresponding operating speed V to the control unit and store them in the memory in the form of an array:

[0072] W = Array[W1, W2, W3, ..., W...] n ] Formula 1;

[0073] V = Array[V1,V2,V3……V n ] Formula 2;

[0074] Wherein, every first preset time T w Record one set of data, and record a total of n sets of data.

[0075] Optionally, the first preset time is 1 second.

[0076] Specifically, in step S102, it can be understood that different brands of cigarettes have different feed ratios, which can be set according to actual needs during production.

[0077] Further, in step S103, based on the feeding ratio, the weight of each material, and the operating speed of the electronic belt scale corresponding to each material weight, the flow rate of the liquid corresponding to each material weight is obtained, including:

[0078] Step S1031: Obtain the theoretical amount of liquid to be added corresponding to the weight of each material based on the weight of each material and the feeding ratio;

[0079] Step S1032: Based on the theoretical amount of liquid to be added corresponding to the weight of each material and the running speed of the electronic belt scale, obtain the first liquid flow rate corresponding to the weight of each material.

[0080] Specifically, the theoretical amount of liquid to be added is calculated using the following formula:

[0081] W 料 =W*P Formula 3;

[0082] Among them W 料 The theoretical weight to be added to the liquid material is W, where W is the weight of the material and P is the addition ratio.

[0083] Based on Formulas 1 and 3 above, the theoretical amount of liquid to be added corresponding to the weight of each material can be obtained:

[0084] W 料 =Array[W 料1 W 料2 W 料3 ...W 料n ] Formula 4;

[0085] Among them, W 料1 W 料2 W 料3 ...W 料n These are respectively related to the weights of each material: W1, W2, W3...W n The corresponding theoretical amount of liquid to be added.

[0086] First preset time T w The theoretical addition amount W of the liquid material 料 Equal to the flow rate V of the liquid feed 料 Multiplied by the first preset time T w Furthermore, the weight of the material can be calculated based on the running speed V and running time of the electronic belt scale 5, yielding the following formula:

[0087] W 料 =W*P= V 料 *T w Formula 5;

[0088] W = V * T w Formula 6;

[0089] Among them, V 料 The flow rate of the liquid feed is denoted as .

[0090] Based on formulas 5 and 6, the following can be calculated:

[0091] V 料 =V*P Formula 7;

[0092] Using formulas 2 and 7, the first flow rate of the liquid corresponding to the weight of each material can be obtained:

[0093] V 1料 =Array[V1*P,V2*P,V3*P......V n *P] Formula 8;

[0094] Among them, V1, V2, V3……V n These represent the flow rates of the liquid corresponding to the weight of each material.

[0095] Further, in step S103, the liquid flow rate corresponding to each material weight is obtained based on the feeding ratio, the weight of each material, and the operating speed of the electronic belt scale corresponding to each material weight. This also includes:

[0096] Step S1033: Obtain the incremental amount of liquid added corresponding to the weight of each material based on the theoretical amount of liquid added corresponding to the weight of each material;

[0097] Step S1034: Based on the incremental amount of liquid added corresponding to the weight of each material and the first preset time, obtain the second liquid flow rate corresponding to the weight of each material;

[0098] Step S1035: Calculate the average value of the first liquid flow rate and the second liquid flow rate corresponding to the weight of each material, and obtain the average liquid flow rate corresponding to the weight of each material as the liquid flow rate corresponding to the weight of the material.

[0099] Specifically, based on the theoretical amount of liquid to be added corresponding to the weight of each material obtained from Formula 4, the theoretical increment of the amount of liquid to be added corresponding to the weight of each material can be obtained:

[0100] W 增i = W 料i -W 料i-1 Formula 9;

[0101] Among them, W 料i-1 To obtain the theoretical addition amount of the (i-1)th feed solution, W 料i To obtain the theoretical addition amount of the liquid at the i-th time interval after a first preset time, W 增i The increment of the theoretical amount of liquid added is the i-th liquid.

[0102] Since the weight of the material measured by the electronic belt scale 5 is the cumulative weight of the material, the increase in the liquid volume and the first preset time T are used to determine the weight. w The second flow rate of the liquid can be calculated:

[0103] V 料 =W 增 / T w Formula 10;

[0104] The second flow rate of the liquid corresponding to the weight of each material is obtained according to Formula 10 above:

[0105] V 2料 =Array[W 增1 / T w W 增2 / T w W 增3 / T w ...W 增n / T w ] Formula 11;

[0106] Among them, W 增1 W 增2 W 增3 ...W 增n These represent the increments in the amount of liquid added corresponding to the weight of each material.

[0107] More specifically, the flow rate of the liquid corresponding to the weight of each material is calculated by determining the first flow rate V of the liquid corresponding to the weight of each material. 1料 Second feed flow rate V 2料 The average feed flow rate is used to obtain:

[0108]

[0109] Since the first liquid flow rate is calculated based on the running speed of the electronic belt scale, and the second liquid flow rate is calculated based on the weight measured by the electronic belt scale 5, and the two are measured and calculated using different sensors, inaccurate measurements may sometimes occur. This technical solution can ensure the accuracy of the liquid flow rate calculation, ensure the feeding accuracy, or even if one of the sensors is damaged, the feeding result can still be obtained, thus avoiding affecting normal production.

[0110] Specifically, the actuator has a linear relationship with the flow rate of the fed liquid, and the relationship is as follows:

[0111] P = kV 料 Formula 13;

[0112] Where P is the execution parameter of the actuator, k is the linearity coefficient, and V 料 The flow rate of the liquid corresponding to the weight of each material.

[0113] Further, in step S104, when actuator 4 is a feeding pump, the execution parameter P is the frequency of the feeding pump, and the linear coefficient k = 50 / X, where X represents the liquid flow rate when the feeding pump frequency reaches its maximum. Therefore, the execution parameter corresponding to each liquid flow rate is determined based on the relationship to determine the frequency of the feeding pump.

[0114] P泵 =Array[50*V 料1 / X,50*V 料2 / X,……50*V 料i / X……50*V 料n Formula 14;

[0115] Among them, P 泵 Indicates the frequency of the feed pump, V 料i This represents the flow rate of the liquid corresponding to the weight of the i-th material.

[0116] Further, in step S104, when actuator 4 is a flow control valve, the execution parameter P is the valve opening of the flow control valve, and the linear coefficient of the linear relationship is k = 100 / Y, where Y represents the liquid flow rate when the valve opening of the flow control valve reaches its maximum. Therefore, determining the execution parameter corresponding to each liquid flow rate based on the relationship determines the valve opening of the flow control valve.

[0117] P 阀 =Array[100*V 料1 / Y,100*V 料2 / Y,……100*V 料i / Y……100*V 料n / Y] Formula 15;

[0118] Among them, P 阀 V represents the valve opening degree of the flow control valve. 料i This represents the flow rate of the liquid corresponding to the weight of the i-th material.

[0119] Optionally, the liquid flow rate X when the frequency of the feed pump reaches its maximum and the liquid flow rate Y when the valve opening of the flow control valve reaches its maximum can both be measured experimentally before production.

[0120] Furthermore, after obtaining the relationship between the execution parameters and the liquid flow rate, and determining the execution parameters corresponding to each liquid flow rate based on the relationship, the process also includes: delaying the actuator for a second preset time and then starting it according to the determined execution parameters.

[0121] Specifically, the second preset time is the time required for the material to be transported from the electronic belt scale 5 to the feeder 1. Since there are also devices such as a feeding trough between the electronic belt scale 5 and the feeder 1, there is a certain distance between the material inlet of the electronic belt scale 1 and the feeder 1. In order to ensure that the material weighed by the electronic belt scale 5 at that time is fed and to improve the feeding accuracy, the time for the liquid material to enter the feeder 1 is delayed by the second preset time to ensure that the batch of material weighed by the electronic belt scale 5 is fed during feeding.

[0122] According to the tobacco feeding control method provided by the present invention, the material weight measured by the electronic belt scale 5 and the running speed of the electronic belt scale 5 at the corresponding time, as well as the feeding ratio of the material, are obtained at first preset time intervals to obtain the liquid flow rate corresponding to each material weight. Furthermore, the execution parameters corresponding to each liquid flow rate are determined according to the relationship between the execution parameters of the actuator and the liquid flow rate. Thus, the liquid flow rate can be determined based on the material weight of the incoming material, thereby determining the execution parameters of the actuator. This avoids the problem of uneven feeding at the feeding head caused by PID adjustment of the execution parameters in the feeding head section.

[0123] The present invention also provides a tobacco feeding control device, which includes a feeder and a storage tank. The feeder is connected to the storage tank via a connecting pipe. Tobacco material is transported to the feeder via an electronic belt scale for liquid addition. The tobacco feeding device also includes an actuator, which controls the liquid flow rate by adjusting its execution parameters, such as... Figure 3 As shown, the tobacco feeding control device includes:

[0124] The first acquisition module 201 is used to acquire the weight of the material weighed by the electronic belt scale and the operating speed of the electronic belt scale at each first preset time interval.

[0125] The second acquisition module 202 is used to acquire the feeding ratio of the liquid material;

[0126] The calculation module 203 is used to obtain the liquid flow rate corresponding to the weight of each material based on the feeding ratio, the weight of each material, and the running speed of the electronic belt scale corresponding to the weight of each material.

[0127] The parameter determination module 204 is used to obtain the relationship between the execution parameters and the flow rate of the liquid, and to determine the execution parameters corresponding to each flow rate of the liquid based on the relationship.

[0128] Furthermore, the calculation module is used to obtain the liquid flow rate corresponding to each material weight based on the feeding ratio, the weight of each material, and the operating speed of the electronic belt scale corresponding to each material weight, including:

[0129] The theoretical amount of liquid to be added is obtained based on the weight of each material and the feeding ratio, corresponding to the weight of each material.

[0130] Based on the theoretical amount of liquid to be added corresponding to the weight of each material and the running speed of the electronic belt scale, the first liquid flow rate corresponding to the weight of each material is obtained.

[0131] Furthermore, the calculation module, used to obtain the liquid flow rate corresponding to each material weight based on the feeding ratio, the weight of each material, and the operating speed of the electronic belt scale corresponding to each material weight, also includes:

[0132] The incremental amount of liquid added corresponding to the weight of each material is obtained based on the theoretical amount of liquid to be added for each material.

[0133] Based on the incremental amount of liquid added corresponding to the weight of each material and the first preset time, the second liquid flow rate corresponding to the weight of each material is obtained;

[0134] Calculate the average of the first and second liquid flow rates corresponding to the weight of each material, and obtain the average liquid flow rate corresponding to the weight of each material as the liquid flow rate corresponding to the weight of the material.

[0135] Furthermore, in the parameter determination module, when the actuator is a feeding pump, the execution parameter is the frequency of the feeding pump.

[0136] The execution parameters corresponding to each liquid flow rate are determined based on the relationship, which in turn determines the frequency of the feed pump.

[0137] P 泵 =Array[50*V 料1 / X,50*V 料2 / X,……50*V 料i / X……50*V 料n Formula 14;

[0138] Among them, P 泵 Indicates the frequency of the feed pump, V 料i Let X represent the flow rate of the liquid corresponding to the weight of the i-th material, and let X represent the flow rate of the liquid when the frequency of the feeding pump reaches its maximum.

[0139] Furthermore, in the parameter determination module, when the actuator is a flow control valve, the execution parameter is the valve opening degree of the flow control valve.

[0140] The execution parameters corresponding to each liquid flow rate are determined based on the relationship, which in turn determines the valve opening of the flow control valve.

[0141] P 阀 =Array[100*V 料1 / Y,100*V 料2 / Y,……100*V 料i / Y……100*V 料n / Y] Formula 15;

[0142] Among them, P 阀 V represents the valve opening degree of the flow control valve. 料i Y represents the liquid flow rate corresponding to the weight of the i-th material, and Y represents the liquid flow rate when the valve opening of the flow control valve reaches its maximum.

[0143] Furthermore, it also includes a delay module, which is used to obtain the relationship between the execution parameters and the liquid flow rate. After determining the execution parameters corresponding to each liquid flow rate based on the relationship, the actuator is delayed for a second preset time and then started according to the determined execution parameters.
