Abstract
Description
Technical Field
[0001] This invention relates to the field of cigarette equipment technology, and more specifically, to a method, system, electronic device, and storage medium for controlling the speed of a tobacco conveyor belt. Background Technology
[0002] In the tobacco industry, feeders are crucial equipment for ensuring continuous production and uniform material distribution. They are among the most frequently used pieces of equipment in the tobacco industry. Feeders are typically used in conjunction with metering tubes. When there is a large accumulation of material on the downstream electronic scale, the high-level metering tube is blocked, and the feeder's conveyor belt stops operating to prevent material buildup and blockage. Conversely, when there is a shortage of material on the downstream electronic scale, the low-level metering tube is exposed, and the feeder's conveyor belt speeds up to prevent material interruption in the downstream equipment. However, in actual operation, situations can arise where the tobacco sheets are too light and fall slowly, blocking the high-level metering tube and causing the feeder's electronic belt scale to stop operating when there is a shortage of material on the downstream electronic scale, resulting in a flow interruption. Additionally, a dirty inner wall of the metering tube or stains on its level detection photoelectric sensor can also cause malfunctions, affecting normal production.
[0003] Therefore, how to provide a method, system, electronic device and storage medium for controlling the speed of tobacco conveyor belt has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of the invention.
[0034] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.
[0035] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.
[0036] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0037] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.
[0038] Example 1:
[0039] This invention discloses a method for controlling the speed of a tobacco lifting belt. Figure 1 A flowchart of a tobacco conveyor belt speed control method according to an embodiment of the present invention is shown below. Figure 1 As shown, the method includes:
[0040] Step S1: Obtain the operating speed data of the electronic scale from the PLC of the electronic scale;
[0041] Step S2: Calculate the running speed of the electronic scale when the quantitative tube level signal is triggered;
[0042] Step S3: Based on the running speed of the electronic scale when the quantitative tube level signal is triggered and the running speed data of the electronic scale, guide the belt speed increase.
[0043] In step S1, the running speed data of the electronic scale is obtained from the PLC of the electronic scale.
[0044] Specifically, a new program segment is added to the feeder PLC system, an S7 one-way communication program is written, and the FB14 function block is used to obtain the running speed data of the electronic scale in the electronic scale PLC.
[0045] In step S2, the running speed of the electronic scale is calculated when the quantitative tube level signal is triggered.
[0046] In some embodiments, in step S2, the operating speed of the electronic scale when the quantitative tube level signal is triggered includes:
[0047] The operating speed of the electronic scale when the high material level signal is triggered and the operating speed of the electronic scale when the low material level signal is triggered.
[0048] In step S3, the speed of the lifting belt is guided based on the running speed of the electronic scale when the quantitative tube level signal is triggered and the running speed data of the electronic scale.
[0049] In some embodiments, in step S3, the method of guiding the belt speed based on the operating speed of the electronic scale when triggered by the quantitative tube level signal includes:
[0050] When the operating speed of the electronic scale exceeds the operating speed triggered by the low material level signal, the lifting belt is controlled to increase its speed.
[0051] When the running speed of the electronic scale is lower than the high material level signal trigger speed, the control belt will stop running.
[0052] Specifically, because the electronic scale uses constant flow control, the total amount of material conveyed by the scale per unit time is fixed. When the material accumulation is small, the scale speeds up; when the material accumulation is large, the scale speeds down. Therefore, by judging the operating speed of the electronic scale, the material accumulation situation on the scale can be determined, which can be used to guide the speed control of the feeder's lifting belt.
[0053] When the operating speed of the electronic scale is greater than the operating speed triggered by the low material level signal, it indicates that there is very little material accumulated on the electronic scale. The speed of the lifting belt is increased (by increasing the speed control word of the feeder lifting belt frequency converter).
[0054] When the operating speed of the electronic scale is lower than the operating speed triggered by the high material level signal, it indicates that there is a lot of material accumulated on the electronic scale, and the lifting belt is controlled to stop running (the speed control word of the feeder lifting belt frequency converter is written to 0).
[0055] In summary, the solution proposed in this invention can achieve automatic speed control of the feeder lifting belt without adding any other equipment, by directly removing the quantitative tube, thereby improving production stability, ensuring production quality, and reducing equipment costs. It has good promotional value.

[0060] The third processing module 103 is configured to guide the belt speed increase based on the running speed of the electronic scale when the quantitative tube level signal is triggered and the running speed data of the electronic scale.
[0061] According to the system of the second aspect of the present invention, the first processing module 101 is specifically configured to add a program segment to the feeder PLC system, write an S7 one-way communication program, and use the FB14 function block to obtain the running speed data of the electronic scale in the electronic scale PLC.
[0062] According to the system of the second aspect of the present invention, the second processing module 102 is specifically configured such that the operating speed of the electronic scale when the quantitative tube level signal is triggered includes:
[0063] The operating speed of the electronic scale when the high material level signal is triggered and the operating speed of the electronic scale when the low material level signal is triggered.
[0064] According to the system of the second aspect of the present invention, the third processing module 103 is specifically configured such that the method of guiding the belt speed according to the running speed of the electronic scale triggered by the quantitative tube level signal includes:
[0065] When the operating speed of the electronic scale exceeds the operating speed triggered by the low material level signal, the lifting belt is controlled to increase its speed.
[0066] When the running speed of the electronic scale is lower than the high material level signal trigger speed, the control belt will stop running.
[0067] Specifically, because the electronic scale uses constant flow control, the total amount of material conveyed by the scale per unit time is fixed. When the material accumulation is small, the scale speeds up; when the material accumulation is large, the scale speeds down. Therefore, by judging the operating speed of the electronic scale, the material accumulation situation on the scale can be determined, which can be used to guide the speed control of the feeder's lifting belt.
[0068] When the operating speed of the electronic scale is greater than the operating speed triggered by the low material level signal, it indicates that there is very little material accumulated on the electronic scale. The speed of the lifting belt is increased (by increasing the speed control word of the feeder lifting belt frequency converter).
