[0002] In the modern tobacco manufacturing industry, the negative pressure of the paper cutting wheel of the cigarette making machine directly affects the quality and production efficiency of cigarettes. The stability of the negative pressure determines the adsorption effect of the paper on the paper cutting wheel, which in turn affects the consistency of the length of the paper cutting and the neatness of the cut, as well as the adhesion effect between the paper and the cigarette, affecting the overall quality of the cigarette.

[0003] At present, the adjustment of the negative pressure of the paper cutting wheel of the cigarette machine mainly relies on external centralized control and the mechanical negative pressure gauge inside the machine body.

[0025] Embodiment 1

[0026] Figure 1 This is a schematic structural diagram of a negative pressure adjustment system for a paper cutting wheel of a cigarette making machine provided in Embodiment 1 of the present invention. This embodiment is applicable to the case of automatically adjusting the negative pressure of a paper cutting wheel of a cigarette making machine.

[0027] Correspondingly, such as Figure 1 As shown, the system includes:

[0028] A negative pressure detection device 110, an electric regulating valve 120 and a controller 130; the negative pressure detection device 110 is arranged at the front of the filter receiving electric cabinet in the cigarette making machine, the electric regulating valve 120 is installed at the negative pressure air source supply of the paper cutting wheel, and the controller 130 is electrically connected to the negative pressure detection device 110 and the electric regulating valve 120 respectively;

[0029] The negative pressure detection device 110 is used to collect the analog voltage value of the negative pressure of the paper cutting wheel in real time, and transmit the collected analog voltage value to the controller 130;

[0030] The controller 130 is used to calculate the negative pressure of the paper cutting wheel in real time according to the analog voltage value; calculate the running speed of the cigarette making machine in real time, and when it is determined that the running speed is greater than the preset low-speed running setting value of the cigarette making machine, combine the negative pressure of the paper cutting wheel, and generate at least one electric valve adjustment instruction to the electric regulating valve according to the preset low-speed setting negative pressure value of the paper cutting wheel, the maximum running speed setting value of the cigarette making machine and the negative pressure compensation value of the paper cutting wheel, so that the negative pressure of the paper cutting wheel is linearly adjusted with the speed of the equipment;

[0031] The electric regulating valve 120 is used to adjust the opening degree of the negative pressure air source of the paper cutting wheel in response to the electric valve adjustment instruction sent by the controller 130.

[0032] In the embodiment of the present invention, the negative pressure detection device can be specifically understood as: a sensor installed at the front of the filter connection cabinet in the cigarette making machine, which is used to measure and collect the current negative pressure of the paper cutting wheel in real time. The electric regulating valve can be specifically understood as: a valve installed at the negative pressure air source supply of the paper cutting wheel, which is used to control the openness of the air source, thereby adjusting the negative pressure of the paper cutting wheel. The controller can be specifically understood as: a part of the system that is electrically connected to the negative pressure detection device and the electric regulating valve, and is used to process sensor data and generate control instructions.

[0033] The low-speed setting value of the cigarette machine can be specifically understood as: a pre-set speed value. When the cigarette machine's operating speed is lower than this value, the system will control the negative pressure of the paper cutting wheel to the low-speed setting paper cutting wheel negative pressure value. The low-speed setting paper cutting wheel negative pressure value can be specifically understood as: when the cigarette machine runs below the low-speed setting value, the negative pressure value that should be set at the paper cutting wheel.

[0034] The negative pressure value of the paper cutting wheel set at low speed needs to be set according to many factors, which may include: the physical properties of the paper materials used, the splicing style of the paper materials, the performance and aging condition of the cigarette making machine, the production process requirements, the changes in the production environment (ambient temperature and humidity and other conditions will affect the physical properties of the paper) and energy consumption and safety standards, to ensure the stable transportation and precise cutting of cigarette paper or tipping paper, while reducing material waste and improving production efficiency, and avoiding equipment damage or operator injury caused by excessive negative pressure.

[0035] The maximum operating speed setting value of the cigarette making machine can be specifically understood as: the maximum operating speed allowed by the cigarette making machine set according to the cigarette making machine performance, production conditions and production plan, etc., which is used as a reference when automatically adjusting the negative pressure. The negative pressure compensation value of the paper cutting wheel can be specifically understood as: the compensation parameter or proportional coefficient used to adjust the negative pressure of the paper cutting wheel when the speed of the cigarette making machine changes, so as to maintain the linear relationship between negative pressure and speed. The electric valve adjustment instruction can be specifically understood as: an instruction to control the opening degree of the electric valve, thereby controlling the opening degree of the air source and adjusting the negative pressure of the paper cutting wheel. Specifically, it can include: when the operating speed of the cigarette making machine exceeds the preset low-speed operation setting value, the controller will generate an instruction to adjust the opening degree of the electric valve according to the current negative pressure of the paper cutting wheel, the operating speed of the cigarette making machine and the preset parameters.

[0036] Specifically, the negative pressure detection device 110 collects the negative pressure value of the paper cutting wheel in real time and transmits the data to the controller 130. The controller 130 calculates the negative pressure of the paper cutting wheel according to the received analog voltage value. Specifically, in the pre-processing production or experimental process, by changing the negative pressure of the paper cutting wheel and measuring the corresponding analog voltage value, the collected data points are used for data fitting to determine the mathematical model between the analog voltage and the negative pressure. For example, when the mathematical model between the analog voltage and the negative pressure is a linear relationship of the form P=a*V+b, where P is the negative pressure value, V is the analog voltage value, and a and b are coefficients obtained by data fitting, then the controller 130 can calculate the negative pressure of the paper cutting wheel in real time according to the received analog voltage value by the pre-constructed mathematical model.

[0037] In addition, a position encoder can be pre-installed on the paper cutting wheel shaft, and the controller 130 determines the running speed of the cigarette making machine by reading the position information provided by the position encoder and calculating the position change rate. Alternatively, when the cigarette making machine is driven by a variable frequency motor, the feedback signal (such as a speed signal) provided by the motor driver can be used to determine the running speed of the cigarette making machine.

[0038] When the running speed of the cigarette machine is greater than the preset low-speed running setting value of the cigarette machine, and the ratio of the calculated paper cutting wheel negative pressure value to the current running speed of the cigarette machine exceeds the preset threshold value, it means that the current paper cutting wheel negative pressure value does not match the current running speed of the cigarette machine, and the paper cutting wheel negative pressure value needs to be adjusted. Specifically, it can be calculated according to the following formula: Negative pressure adjustment value = low-speed setting paper cutting wheel negative pressure value + (maximum running speed setting value - current running speed of the cigarette machine) × paper cutting wheel negative pressure compensation value. The negative pressure adjustment value matching the current running speed of the cigarette machine is calculated, and at least one electric valve adjustment instruction is automatically generated and sent to the electric regulating valve to adjust the opening degree of the electric regulating valve so that the negative pressure of the paper cutting wheel is adjusted linearly with the equipment speed, and finally the ratio of the negative pressure of the paper cutting wheel to the current running speed of the cigarette machine satisfies the linear relationship within the preset threshold value.

[0039] Due to differences in production sites and production plans, operators may frequently adjust the equipment speed, and the equipment does not always run at a fixed speed. Therefore, this mechanism monitors in real time and automatically adjusts the negative pressure value to adapt to changes in the cigarette machine's operating speed, ensuring that during the entire acceleration process from low speed to maximum speed, the stability of paper material transportation and packaging quality are effectively guaranteed.

[0040] The negative pressure adjustment system for the paper cutting wheel of a cigarette making machine according to an embodiment of the present invention comprises: a negative pressure detection device, an electric regulating valve and a controller; the negative pressure detection device is arranged at the front part of the filter connecting electric cabinet in the cigarette making machine, the electric regulating valve is installed at the negative pressure air source supply of the paper cutting wheel, and the controller is electrically connected to the negative pressure detection device and the electric regulating valve respectively; the negative pressure detection device is used to collect the analog voltage value of the negative pressure of the paper cutting wheel in real time, and transmit the collected analog voltage value to the controller; the controller is used to adjust the negative pressure of the paper cutting wheel according to the analog voltage value Calculate the negative pressure of the paper cutting wheel in real time; calculate the running speed of the cigarette making machine in real time, and when it is determined that the running speed is greater than the preset low-speed running setting value of the cigarette making machine, combine the negative pressure of the paper cutting wheel, according to the preset low-speed setting negative pressure value of the paper cutting wheel, the maximum running speed setting value of the cigarette making machine and the negative pressure compensation value of the paper cutting wheel, generate at least one electric valve adjustment instruction and send it to the electric regulating valve, so that the negative pressure of the paper cutting wheel follows the linear adjustment of the equipment speed; the electric regulating valve is used to adjust the openness of the negative pressure gas source of the paper cutting wheel in response to the electric valve adjustment instruction sent by the controller. By responding to the changes in production demand and equipment status in real time, the negative pressure of the paper cutting wheel is automatically adjusted in time to ensure that the paper is closely attached to the paper cutting wheel during the cutting process, to ensure the accuracy and stability of the cutting, to avoid production interruption and waste caused by abnormal negative pressure, to reduce production costs and manpower adjustment costs, to ensure the continuity of production, and to improve the production efficiency and quality level of products.

[0041] Optionally, based on the above embodiments, the controller is electrically connected to a pulse sensor on a body of a cigarette forming device in the cigarette making machine;

[0042] The controller is specifically used to calculate the running speed of the cigarette making machine in real time according to the serial communication protocol pulse signal obtained in real time from the pulse sensor.

[0043] In the embodiment of the present invention, the pulse sensor refers to a sensor installed on a key component such as a transmission shaft or a paper cutting wheel of a paper reel to monitor its rotation speed or position. Whenever the component completes a specific action or rotates a certain angle, the pulse sensor generates a pulse signal.

[0044] The frequency of the signal is proportional to the speed of the device, that is, the faster the component runs, the faster the pulse sensor senses. The operating speed can be calculated through the frequency value of the sensor output signal, for example: speed = pulse frequency / unit pulse number, where speed is the operating speed of the device, pulse frequency is the frequency value of the sensor sensing output signal, and unit pulse number is the number of pulses generated when the component completes a specific action or rotates a certain angle.

[0045] Serial communication protocol pulse signal refers to a pulse signal transmitted through serial communication (data bits are transmitted one by one in sequence, following a specific serial communication protocol such as RS-232 or RS-485), which is used to determine the position, speed, acceleration, etc. of the device.

[0046] Specifically, the controller is directly connected to the pulse sensor installed on the cigarette making machine through electrical means (such as wires, wiring terminals, connectors or interfaces, etc.) to receive the serial communication protocol pulse signal from the sensor, and can calculate the running speed of the cigarette making machine in real time through speed = pulse frequency / unit pulse number. Through the precise pulse signal provided by the pulse sensor, the controller can accurately calculate the real-time speed of the cigarette making machine, thereby achieving more precise negative pressure control, reducing production interruptions caused by the mismatch between negative pressure and speed, and improving the efficiency, stability and continuity of the entire production process, thereby improving the overall quality of the product.

[0047] Further, based on the above embodiments, the negative pressure adjustment system for the paper cutting wheel of the cigarette making machine may further include: a knob switch, the knob switch is electrically connected to the controller;

[0048] The rotary switch is used to be controlled to switch from a closed state to an open state when the cigarette making machine needs to insert the three-section tipping paper, and to be controlled to switch from an open state to a closed state when the three-section tipping paper is correctly inserted into the rolling press;

[0049] The controller is further used to generate an electric valve adjustment instruction according to a preset paper threading negative pressure value and send it to the electric regulating valve when detecting that the rotary switch is switched from a closed state to an open state, so as to electrically adjust the opening degree of the negative pressure air source of the paper cutting wheel to match the paper threading negative pressure value;

[0050] Furthermore, when it is detected that the rotary switch switches from an open state to a closed state, an electric valve adjustment instruction is generated according to the preset low-speed setting paper cutting wheel negative pressure value and sent to the electric regulating valve, so that the electric regulating valve adjusts the opening degree of the paper cutting wheel negative pressure source to match the low-speed setting paper cutting wheel negative pressure value.

[0051] In the embodiment of the present invention, the rotary switch refers to a switch electrically connected to the input end of the controller and used to control the operating mode of the cigarette making machine. When the cigarette making machine needs to insert three-section tipping paper or other types of paper materials, the switch is switched from a closed state to an open state. When the three-section tipping paper or other types of paper materials are correctly inserted into the rolling machine, the switch is switched from an open state to a closed state.

[0052] The rotary switch can be opened and closed manually, or when the controller in the system detects the need to replace the three-section tipping paper or other types of paper materials (for example, using a photoelectric sensor to detect the end of the paper material, when the light beam of the photoelectric sensor is blocked, that is, the paper material is exhausted, the sensor will send a signal to the controller), the controller automatically sends a control signal to trigger the switch to open, so as to insert the three-section tipping paper or other types of paper materials, and automatically switches to the closed state after the three-section tipping paper or other types of paper materials are correctly inserted into the rolling machine.

[0053] Three-section tipping paper is a special type of tipping paper, which consists of three sections with joints between each section to achieve a specific packaging effect or function. The preset paper penetration negative pressure value can be specifically understood as: a negative pressure value preset by the system when inserting the three-section tipping paper. The negative pressure is used to ensure that the tipping paper will not be pulled apart or wrinkled, and can be correctly conveyed and positioned to facilitate the subsequent cutting and packaging process.

[0054] The paper-threading negative pressure value can be specifically understood as: in a cigarette-making machine, the negative pressure used to ensure that paper materials (such as cigarette paper or tipping paper, etc.) can pass through smoothly, be correctly spliced ​​and adsorbed on the paper cutting wheel.

[0055] Specifically, when the controller detects that the rotary switch switches from a closed state to an open state, the controller generates an adjustment instruction according to the preset paper-threading negative pressure value, sends it to the electric regulating valve, adjusts the opening degree of the negative pressure air source of the paper-cutting wheel, so as to adjust the negative pressure of the paper-cutting wheel to a suitable paper-threading negative pressure value, and ensures that the negative pressure matches the preset value. When the rotary switch switches from an open state back to a closed state, the controller generates another adjustment instruction according to the preset low-speed setting paper-cutting wheel negative pressure value, sends it to the electric regulating valve, adjusts the opening degree of the negative pressure air source of the paper-cutting wheel, so as to adjust the negative pressure of the paper-cutting wheel to the low-speed setting value, and ensures that the negative pressure matches the preset value.

[0056] The system can automatically adjust the negative pressure according to different production conditions (such as paper threading and low-speed operation), which enhances the adaptability and flexibility of the equipment. By accurately controlling the insertion of the three-stage kraft paper and the negative pressure during the cigarette rolling process, it reduces material waste caused by improper operation, optimizes energy use, reduces unnecessary energy consumption, avoids production interruptions and waste generation due to abnormal negative pressure, reduces production costs and manpower adjustment costs, ensures production continuity, and improves product production efficiency and quality level.

[0057] Optionally, based on the above embodiments, the controller is electrically connected to the normally open contact of the knob switch, and the knob switch is arranged on the operation panel of the filter connection electric cabinet in the cigarette making machine.

[0058] Specifically, the operator can change the working mode of the cigarette making machine by simply rotating the switch, such as when the cigarette making machine needs to insert the three-section tipping paper, the controlled state is switched from the closed state to the open state, and when the three-section tipping paper is correctly inserted into the rolling press, the controlled state is switched from the open state to the closed state. The controller can directly respond to the state change of the knob switch, execute the corresponding control logic, and realize the automatic control of the cigarette making machine.

[0059] By electrically connecting the controller to the normally open contacts of the knob switch on the operation panel of the filter plugging cabinet in the cigarette making machine, the operation process of the operator is simplified, and the response speed and automation level of the production line are improved. In addition, centralizing the control components on the operation panel helps to centralize monitoring and maintenance, thereby reducing potential misoperations and improving production efficiency, allowing operators to intervene in the production process in a timely manner, ensuring the flexibility and continuity of the production process, and also facilitating fault diagnosis and maintenance, further reducing maintenance costs and improving overall production performance.

[0060] Furthermore, based on the above embodiments, the negative pressure adjustment system of the paper cutting wheel of the cigarette making machine may also include: a touch screen; the touch screen is used to set the low-speed operation value of the cigarette making machine, the low-speed setting paper cutting wheel negative pressure value, the maximum operating speed value of the cigarette making machine and the paper cutting wheel negative pressure compensation value.

[0061] Specifically, a touch screen is integrated in the negative pressure adjustment system of the paper cutter wheel of the cigarette machine. The operator can intuitively input and adjust parameters such as the low-speed operation value of the cigarette machine, the low-speed setting negative pressure value of the paper cutter wheel, the maximum operating speed value of the cigarette machine and the negative pressure compensation value of the paper cutter wheel through the touch screen, thereby reducing operating errors and improving the accuracy of the settings, thereby achieving precise control of the negative pressure of the paper cutter wheel, and helping operators to quickly respond to changes in production needs, such as adjusting production speed, switching product specifications or other preset parameters, further improving the automation level and adaptability of the system, reducing energy consumption, reducing material waste, and improving product quality and production efficiency.

[0062] Optionally, based on the above embodiments, the controller is a programmable controller;

[0063] Among them, the input pin of the programmable controller is used to be electrically connected to the negative pressure detection device and the knob switch; the output pin of the programmable controller is used to be electrically connected to the electric regulating valve.

[0064] Specifically, the controller is a programmable logic controller (PLC), and the input pins of the PLC are used to receive signals from the negative pressure detection device and the knob switch, which can be analog signals or digital signals to indicate the current negative pressure state and the position of the knob switch. The output pins of the PLC are connected to the electric regulating valve to control the action of the valve, such as opening, closing or opening degree, to adjust the gas supply of the negative pressure gas source, and then to adjust the negative pressure of the paper cutting wheel.

[0065] By using a programmable controller, the system can monitor and respond to changes in negative pressure in real time, ensuring that the negative pressure of the paper cutting wheel can be automatically and accurately adjusted according to preset parameters or the operator's instructions, improving the convenience of operation and the response speed of the system, enhancing the reliability and stability of the system, ensuring that the paper fits tightly to the paper cutting wheel during the cutting process, ensuring the accuracy and stability of the cutting, avoiding production interruptions and waste generation due to abnormal negative pressure, reducing production costs and manpower adjustment costs, ensuring production continuity, and improving product production efficiency and quality levels.

[0066] Embodiment 2

[0067] Figure 2 This is a flow chart of a method for adjusting the negative pressure of a paper cutting wheel of a cigarette making machine provided in the second embodiment of the present invention. This embodiment is applicable to the case of automatically adjusting the negative pressure of a paper cutting wheel in a cigarette making machine. The method can be executed by a controller configured in a negative pressure adjustment system of a paper cutting wheel of a cigarette making machine.

[0068] Correspondingly, such as Figure 2 As shown, the method includes:

[0069] S210, obtaining the analog voltage of the negative pressure of the paper cutting wheel collected in real time by the negative pressure detection device, and calculating the negative pressure of the paper cutting wheel in real time according to the analog voltage value.

[0070] S220, calculating the running speed of the cigarette making machine in real time, and determining in real time whether the running speed is greater than a preset low-speed running setting value of the cigarette making machine.

[0071] S230, when the running speed is greater than the preset low-speed running setting value of the cigarette making machine, in combination with the paper cutting wheel negative pressure, according to the preset low-speed setting paper cutting wheel negative pressure value, the maximum running speed setting value of the cigarette making machine and the paper cutting wheel negative pressure compensation value, at least one electric valve adjustment instruction is generated and sent to the electric regulating valve, so that the negative pressure of the paper cutting wheel is linearly adjusted following the equipment speed.

[0072] Specifically, in the negative pressure adjustment system of the paper cutting wheel of the cigarette making machine, the controller collects the negative pressure analog voltage value of the paper cutting wheel in real time through the negative pressure detection device, and calculates the current negative pressure of the paper cutting wheel in real time by the pre-built mathematical model. At the same time, the controller calculates the running speed of the cigarette making machine in real time. Specifically, a position encoder can be installed on the paper cutting wheel shaft in advance, and the controller reads the position information provided by the position encoder, and determines the running speed of the cigarette making machine by calculating the position change rate. Alternatively, when the cigarette making machine is driven by a variable frequency motor, the feedback signal (such as a speed signal) provided by the motor driver can be used to determine the running speed of the cigarette making machine, and determine whether the speed exceeds the preset low-speed running value.

[0073] When the running speed exceeds the preset low speed value, and the ratio of the calculated paper cutting wheel negative pressure value to the current running speed of the cigarette making machine exceeds the preset threshold value, it means that the current paper cutting wheel negative pressure value does not match the current running speed of the cigarette making machine, and the paper cutting wheel negative pressure value needs to be adjusted. The system will set the paper cutting wheel negative pressure value according to the preset low speed, the maximum running speed setting value of the cigarette making machine and the paper cutting wheel negative pressure compensation value, according to the following formula: Negative pressure adjustment value = low speed setting paper cutting wheel negative pressure value + (maximum running speed setting value - current running speed of the cigarette making machine) × paper cutting wheel negative pressure compensation value, calculate the negative pressure adjustment value that matches the current running speed of the cigarette making machine, and automatically generate at least one electric valve adjustment instruction to send to the electric regulating valve, adjust the opening degree of the electric regulating valve, so that the negative pressure of the paper cutting wheel follows the linear adjustment of the equipment speed, and finally make the ratio of the negative pressure of the paper cutting wheel to the running speed of the current cigarette making machine satisfy the linear relationship within the preset threshold value.

[0074] The technical solution of the embodiment of the present invention obtains the analog voltage of the negative pressure of the paper cutting wheel collected in real time by the negative pressure detection device, and calculates the negative pressure of the paper cutting wheel in real time according to the analog voltage value; calculates the running speed of the cigarette making machine in real time, and judges in real time whether the running speed is greater than the preset low-speed running setting value of the cigarette making machine; when the running speed is greater than the preset low-speed running setting value of the cigarette making machine, combined with the negative pressure of the paper cutting wheel, according to the preset low-speed setting negative pressure value of the paper cutting wheel, the maximum running speed setting value of the cigarette making machine and the negative pressure compensation value of the paper cutting wheel, at least one electric valve adjustment instruction is generated and sent to the electric regulating valve, so that the negative pressure of the paper cutting wheel follows the linear adjustment of the equipment speed. By responding to the changes in production demand and equipment status in real time, the negative pressure of the paper cutting wheel is adjusted automatically and timely, ensuring that the paper is closely attached to the paper cutting wheel during the cutting process, ensuring the accuracy and stability of cutting, avoiding production interruption and waste generation due to abnormal negative pressure, reducing production costs and manpower adjustment costs, ensuring the continuity of production, and improving the production efficiency and quality level of products.

[0075] Further, based on the above embodiments, the method for adjusting the negative pressure of the paper cutting wheel of the cigarette making machine may further include:

[0076] A serial communication protocol pulse signal obtained in real time from a pulse sensor on the cigarette forming device of the cigarette making machine;

[0077] The running speed of the cigarette making machine is calculated in real time according to the serial communication protocol pulse signal.

[0078] Specifically, in the negative pressure adjustment system of the paper cutting wheel of the cigarette making machine, the controller obtains the serial communication protocol pulse signal from the pulse sensor, and can calculate the running speed of the cigarette making machine in real time through speed = pulse frequency / unit pulse number, wherein speed is the running speed of the equipment, pulse frequency is the frequency value of the sensor sensing output signal, and unit pulse number is the number of pulses generated when the component completes a specific action or rotates a certain angle.

[0079] Through the precise pulse signal provided by the pulse sensor, the controller can accurately calculate the real-time speed of the cigarette machine, achieve more precise negative pressure control, reduce production interruptions caused by mismatch between negative pressure and speed, and improve the efficiency, stability and continuity of the entire production process, thereby improving the overall product quality.

[0080] Further, based on the above embodiments, the method for adjusting the negative pressure of the paper cutting wheel of the cigarette making machine may further include:

[0081] When it is detected that the rotary switch is switched from the closed state to the open state, an electric valve adjustment instruction is generated according to the preset paper threading negative pressure value and sent to the electric regulating valve, so that the electric regulating valve adjusts the opening degree of the negative pressure air source of the paper cutting wheel to match the paper threading negative pressure value;

[0082] When it is detected that the rotary switch switches from an open state to a closed state, an electric valve adjustment instruction is generated according to the preset low-speed setting paper cutting wheel negative pressure value and sent to the electric regulating valve, so that the electric regulating valve adjusts the opening degree of the paper cutting wheel negative pressure source to match the low-speed setting paper cutting wheel negative pressure value.

[0083] Specifically, in the negative pressure adjustment system of the paper cutting wheel of the cigarette making machine, when the controller detects that the rotary switch is switched from the closed state to the open state, it generates an adjustment instruction according to the preset paper threading negative pressure value, sends it to the electric regulating valve, adjusts the openness of the negative pressure air source of the paper cutting wheel, so as to adjust the negative pressure of the paper cutting wheel to the appropriate paper threading negative pressure value, and ensures that the negative pressure matches the preset value. When the rotary switch is switched from the open state back to the closed state, the controller generates another adjustment instruction according to the preset low-speed setting paper cutting wheel negative pressure value, sends it to the electric regulating valve, adjusts the openness of the negative pressure air source of the paper cutting wheel, so as to adjust the negative pressure of the paper cutting wheel to the low-speed setting value, and ensures that the negative pressure matches the preset value.

[0084] The system can automatically adjust the negative pressure according to different production conditions (such as paper threading and low-speed operation), which enhances the adaptability and flexibility of the equipment. By precisely controlling the paper threading and the negative pressure during the cigarette rolling process, it reduces material waste caused by improper operation, optimizes energy use, reduces unnecessary energy consumption, avoids production interruptions and waste generation due to abnormal negative pressure, reduces production costs and manpower adjustment costs, ensures production continuity, and improves product production efficiency and quality level.

[0085] Further, based on the above embodiments, the method for adjusting the negative pressure of the paper cutting wheel of the cigarette making machine may further include:

[0086] In response to the low-speed operating value of the cigarette machine, the low-speed setting paper cutting wheel negative pressure value, the maximum operating speed value of the cigarette machine and the paper cutting wheel negative pressure compensation value set through the touch screen, the low-speed operating value of the cigarette machine, the low-speed setting paper cutting wheel negative pressure value, the maximum operating speed value of the cigarette machine and the paper cutting wheel negative pressure compensation value are stored.

[0087] Specifically, in the negative pressure adjustment system of the paper cutting wheel of the cigarette making machine, the controller responds to the low-speed operation value of the cigarette making machine, the low-speed setting paper cutting wheel negative pressure value, the maximum operation speed value of the cigarette making machine and the negative pressure compensation value of the paper cutting wheel set through the touch screen, and stores these parameters in its internal memory for real-time access and application during operation. The controller can respond to changes in production demand and equipment status in real time, and automatically adjust the negative pressure of the paper cutting wheel in a timely manner to ensure that the paper fits the paper cutting wheel tightly during the cutting process, ensure the accuracy and stability of the cutting, avoid production interruptions and waste due to abnormal negative pressure, reduce production costs and manpower adjustment costs, ensure the continuity of production, and improve product production efficiency and quality level.

[0088] Specific application scenarios

[0089] At present, the negative pressure of the paper cutting wheel of the ZJ17 cigarette making machine is centrally controlled by the outside. A mechanical negative pressure gauge is installed inside the equipment body to detect the negative pressure. However, the negative pressure cannot be adjusted automatically, which will have many effects on the transportation of paper materials (such as tipping paper). The paper cutting wheel absorbs the tipping paper through negative pressure suction for cutting. Unstable negative pressure will make the adsorption state of the tipping paper on the paper cutting wheel unstable, resulting in problems such as inconsistent cutting length and uneven cutting of the tipping paper, affecting the appearance quality of the cigarette. For example, the length of the tipping paper pieces may be uneven, making the packaging of the cigarette unsightly and even affecting the sealing effect of the cigarette. Unstable negative pressure will affect the pasting effect of the tipping paper and the cigarette. If the negative pressure is too small, the tipping paper may not be firmly pasted on the cigarette, and the tipping paper may fall off easily; if the negative pressure is too large, the tipping paper may be over-stretched or deformed, resulting in wrinkles and bubbles on the tipping paper after pasting.

[0090] Since negative pressure is centrally controlled, the startup and operation of different machines will affect the instability of negative pressure. The negative pressure is unstable and cannot be adjusted automatically. Operators need to frequently stop the machine to manually adjust the negative pressure of the paper cutting wheel to ensure the production quality of cigarettes. This will not only increase the workload of operators, but also increase the downtime of the equipment, reduce the production efficiency of the equipment, and affect the progress of production plans and product output. In particular, for the three-stage tipping paper product style, due to the tipping paper slitting process, during the first paper threading and slitting process, if the negative pressure of the paper cutting wheel is too large, the paper will be directly pulled apart, resulting in the inability to cut and transport the tipping paper, causing production interruption.

[0091] Unstable negative pressure can also cause problems in cutting and pasting the tipping paper, resulting in a large amount of waste. The tipping paper in these waste products cannot be used anymore, resulting in a waste of tipping paper materials. In addition, if the tipping paper is blocked or entangled in the equipment due to negative pressure problems, it will also damage the tipping paper and increase the waste of materials. In the production process of cigarettes, if there are problems in cutting and pasting the tipping paper, it may also cause incomplete packaging or poor sealing of the cigarettes, exposing the tobacco. These exposed tobacco cannot be used in production anymore, which will also result in a waste of tobacco materials.

[0092] Since the negative pressure of the paper cutting wheel cannot be monitored in time, the operator cannot understand the changes in the negative pressure in real time, and it is difficult to discover the problem of unstable negative pressure in time, which will cause the problem to gradually accumulate in the production process and will not be discovered until a large amount of waste is generated or equipment fails, increasing production costs.

[0093] In order to solve the above problems, the embodiment of the present invention provides a negative pressure adjustment system for a paper cutting wheel of a cigarette making machine. Figure 3 1 is a schematic diagram of an electric valve installation applicable to an embodiment of the present invention. Figure 4 is an electric valve installation scene diagram applicable to the embodiment of the present invention, which is Figure 3 Correspondingly, Figure 5 This is an electrical schematic diagram of a negative pressure adjustment system for a paper cutting wheel of a cigarette making machine applicable to an embodiment of the present invention. Taking the ZJ17 cigarette making machine as an example, the system is composed of a Siemens PLC, a touch screen, an electric regulating valve Y1, a negative pressure detection device B1 and a knob switch S1. Among them, the CPU (Central Processing Unit) in the Siemens PLC is a 224xp model. In the figure, M is the common end of the analog input module, which is generally connected to the negative pole of the power supply. I is the current type analog output, and A+ is the analog input channel 1.

[0094] The ZJ17 cigarette making machine includes MAX and SE electric cabinets, which contain various electrical components and terminals. The MAX electric cabinet is the electric control cabinet responsible for the cigarette connection part of the cigarette making machine, responsible for connecting cigarettes and filters to form a complete cigarette product; the SE electric cabinet is the electric control cabinet responsible for the cigarette rolling part of the cigarette making machine, responsible for rolling tobacco into cigarettes and cutting them into specified lengths.

[0095] A Siemens S7-200 PLC is installed in the SE electrical cabinet of the ZJ17 cigarette making machine. The PLC is powered by a positive 24 volt power line (L1 terminal connected to +24V) and a negative 24 volt power line (M terminal connected to -24V). A negative pressure detection device B1 is installed in the front of the MAX electrical cabinet of the ZJ17 cigarette making machine. On the one hand, the operator can observe the current negative pressure value of the paper cutting wheel, and on the other hand, it can provide the detection value to the PLC. The positive power line of the negative pressure detection device B1 is connected to the 24V positive pole, the negative power line is connected to the 24V negative pole, and the data output line is connected to the S7-200 PLC analog input channel 1 (corresponding to the A+ channel), which transmits the specific analog value of the negative pressure of the paper cutting wheel to the PLC, and the PLC calculates the specific value of the negative pressure of the paper cutting wheel through this value.

[0096] Connect the input terminal I0.0 of the S7-200 PLC to the X24 terminal pin 5 of the ZJ17 cigarette machine SE cabinet to collect the SCP (Serial Communication Pulse signal) pulse signal, so as to calculate the running speed of the cigarette machine. The X24 terminal is a terminal block in the ZJ17 cigarette machine, which is used to connect various signal lines. Pin 5 is the 5th connection point in the X24 terminal block. Among them, SCP is a pulse sensor installed on the SE body. The faster the device speed, the faster the sensor senses. According to the frequency value of the sensor output signal, the current running speed can be calculated, that is, speed = pulse frequency / number of pulses per revolution, among which speed is the running speed of the device, pulse frequency is the frequency of the sensor sensing output, and number of pulses per revolution is the number of pulses generated by the device per revolution.

[0097] The input terminal I0.1 of the PLC is connected to the normally open contact of the knob switch S1 installed on the operation panel of the MAX electric cabinet, and the other end of the contact is connected to the positive pole of 24V. At the negative pressure gas supply of the paper cutting wheel of the MAX electric cabinet, a new electric regulating valve Y1 is added to adjust the negative pressure of the paper cutting wheel. The positive power line of the electric valve is connected to the positive pole of 24V, the negative power line is connected to the negative pole of 24V, and the data input line is connected to the analog output channel of the PLC (corresponding to the I channel).

[0098] The PLC adjusts and controls the electric valve to adjust the negative pressure value of the paper cutting wheel to the preset value, which is set by the touch screen installed on the cigarette machine body. The touch screen is powered by 24V positive and 24V negative power, and the COM1 port (Communication Port 1, serial communication port 1) is connected to the COM1 port on the PLC, and communication control is performed through the RS485 protocol. Among them, the wiring terminals and pins in the electrical cabinet are determined by the internal wiring of the equipment. The selection of its terminals and pins is related to the model of the cigarette machine, so the selected connection method is fixed, and the input and output terminals of the PLC can be adjusted and designed according to specific application requirements.

[0099] When the ZJ17 cigarette making machine is ready for production, the analog input channel 1 of the S7-200 PLC will collect the analog voltage value of the negative pressure detection B1 to calculate the current negative pressure of the paper cutting wheel. When the equipment needs to re-insert the three-stage tipping paper, the suction holes on the paper cutting wheel have not been covered with tipping paper, resulting in pressure relief. At this time, the negative pressure value collected by the negative pressure sensor B1 is inaccurate. The knob switch S1 can be manually operated. After the S7-200 PLC input terminal I0.1 receives the knob switch S1 signal, the PLC analog output point controls the electric valve Y1 to operate and run to the constant smaller valve opening set on the touch screen to maintain a smaller paper insertion negative pressure value to ensure that the tipping paper can be transported normally and will not be pulled apart.

[0100] When the tipping paper is correctly inserted, the PLC controls the electric valve Y1 to operate until it reaches the constant small low-speed negative pressure value set on the touch screen, ensuring that the tipping paper can be transported normally and will not be broken when running at a low speed. In addition, after the tipping paper is correctly inserted, the knob switch S1 can be manually closed.

[0101] S7-200 PLC input terminal I0.0 collects ZJ17 cigarette machine SCP pulse signal to calculate the cigarette machine running speed. The low-speed running setting value of the cigarette machine, the low-speed setting paper cutting wheel negative pressure value, the maximum running speed setting value of the cigarette machine and the paper cutting wheel negative pressure compensation value are pre-set on the touch screen interface. PLC calculates the proportional relationship between the paper cutting wheel negative pressure value and the cigarette machine running speed through internal program according to the above parameters.

[0102] When the cigarette machine running speed exceeds the low-speed running setting value, the electric valve Y1 is controlled to operate according to the parameters set on the screen, so that the negative pressure of the paper cutting wheel is automatically adjusted and increased with the equipment speed, that is: when the equipment running speed is lower than the low-speed running setting value, the system will control the negative pressure to the low-speed setting paper cutting wheel negative pressure value to ensure the stability of paper material transportation; when the equipment running speed exceeds the low-speed running setting value, and the ratio of the calculated paper cutting wheel negative pressure value to the current cigarette machine running speed exceeds the preset threshold value, it means that the current paper cutting wheel negative pressure value does not match the current cigarette machine running speed, and the paper cutting wheel negative pressure value needs to be adjusted. The system will adjust the current negative pressure according to these four preset values, as follows: Negative pressure adjustment value = low-speed setting paper cutting wheel negative pressure value + (maximum running speed setting value - current speed) × paper cutting wheel negative pressure compensation value, so as to achieve a linear increase in negative pressure with the equipment speed, and ensure that the negative pressure value and the cigarette machine running speed maintain a constant proportional relationship or are within the preset range of variation. Since operators may frequently adjust the equipment's operating speed and the equipment does not always run at a fixed speed, this mechanism monitors and adjusts the negative pressure value in real time to adapt to changes in the operating speed, ensuring that the stability of paper material transportation and packaging quality are effectively guaranteed during the entire acceleration process from low speed to maximum speed.

[0103] A negative pressure adjustment system for a paper cutting wheel of a cigarette making machine proposed in an embodiment of the present invention can effectively control the negative pressure of a paper cutting wheel of a tipping paper, and automatically adjust the negative pressure according to the running speed of the equipment to ensure the stable conveying of the tipping paper; its automatic adjustment function can adjust the negative pressure in real time according to production requirements and equipment status without manual intervention, thereby reducing the adjustment time of the equipment and improving production efficiency. In addition, the system can adapt to changes in raw material characteristics and production speed, so that the paper can fit closely to the paper cutting wheel during the cutting process, ensuring the accuracy and consistency of the cutting, and ensuring the appearance quality and dimensional accuracy of the cigarette. For example, when producing slim cigarettes or cigarettes of special specifications, accurate negative pressure control can better meet the quality requirements of the product. By real-time monitoring of the negative pressure of the paper cutting wheel, once an abnormal negative pressure is found, the system can be adjusted in time to avoid the problem of uneven paper cutting and paper jams caused by negative pressure problems, thereby avoiding the generation of a large amount of waste, ensuring the stability and efficiency of the paper cutting process, reducing the waste of raw materials and production interruptions, reducing the scrap rate and production costs, and improving the effective operation time of the equipment, the qualified rate of the product and the overall quality level.
