[0025] Embodiment one

[0026] Figure 1 is a structural schematic diagram of a cigarette machine paper cutting wheel negative pressure adjustment system provided for the first embodiment of the present application. The present embodiment can be applicable to the case of automatically adjusting the negative pressure value of the paper cutting wheel of the cigarette machine.

[0027] Correspondingly, as shown in Figure 1 , the system comprises:

[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 part of the filter tip mounting electric cabinet in the cigarette machine, the electric regulating valve 120 is installed at the paper cutting wheel negative pressure air source supply, and the controller 130 is electrically connected with the negative pressure detection device 110 and the electric regulating valve 120 respectively;

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

[0030] The controller 130 is configured to calculate the negative pressure value of the 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 a preset low-speed running setting value of the cigarette making machine, generate at least one electric regulating valve adjustment instruction according to the preset low-speed setting negative pressure value of the cutting wheel, the maximum running speed setting value of the cigarette making machine, and the negative pressure compensation value of the cutting wheel in combination with the negative pressure value of the cutting wheel, and send the electric regulating valve adjustment instruction to the electric regulating valve, so that the negative pressure value of the cutting wheel is adjusted linearly along with the running speed of the equipment.

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

[0032] In the embodiment of the present application, the negative pressure detection device can be specifically understood as a sensor installed in the front part of the filter tip mounting electric cabinet of the cigarette making machine, which is used to measure and collect the current negative pressure value of the 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 cutting wheel, which is used to control the opening degree of the air source, so as to adjust the negative pressure value of the cutting wheel. The controller can be specifically understood as a part in the system which is electrically connected with the negative pressure detection device and the electric regulating valve, and is used to process the sensor data and generate control instructions.

[0033] The low-speed running setting value of the cigarette making machine can be specifically understood as a preset speed value. When the running speed of the cigarette making machine is lower than this value, the system will control the negative pressure value of the cutting wheel to be the low-speed setting negative pressure value of the cutting wheel.

[0034] The low-speed setting negative pressure value of the cutting wheel needs to be set according to various factors, which can include the physical properties of the paper material used, the splicing style of the paper material, the performance and aging condition of the cigarette making machine, the production process requirements, the change of the production environment (such as the conditions of environmental temperature and humidity which can affect the physical properties of the paper), the energy consumption and safety standards, to ensure the stable conveying and accurate cutting of the cigarette paper or water-proof paper, reduce material waste and improve production efficiency, and avoid equipment damage or operator injury caused by excessive negative pressure.

[0035] The maximum operating speed setting value of the cigarette making machine can be understood as the maximum operating speed allowed by the cigarette making machine according to the performance of the cigarette making machine, production conditions and production plans, and is used as a reference when automatically adjusting the negative pressure. The negative pressure compensation value of the cutting wheel can be understood as a compensation parameter or a proportional coefficient for adjusting the negative pressure of the cutting wheel when the speed of the cigarette making machine changes, so as to maintain the linear relationship between the negative pressure and the speed. The electric regulating valve adjustment instruction can be understood as an instruction for controlling the opening degree of the electric regulating valve, thereby controlling the opening degree of the air source and adjusting the negative pressure of the cutting wheel. Specifically, when the operating speed of the cigarette making machine exceeds the preset low-speed operating setting value, the controller generates an instruction for adjusting the opening degree of the electric regulating valve according to the current negative pressure value of the 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 cutting wheel in real time and transmits the data to the controller 130. The controller 130 calculates the negative pressure value of the cutting wheel according to the received analog voltage value. Specifically, in the pre-processing production or experimental process, the negative pressure of the cutting wheel is changed and the corresponding analog voltage value is measured, and 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 such as P=a*V+b, where P is the negative pressure value, V is the analog voltage value, and a and b are the coefficients obtained by data fitting, then the controller 130 can calculate the negative pressure value of the 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 installed at the cutting wheel shaft in advance. The controller 130 determines the operating speed of the cigarette making machine by calculating the position change rate through the position information provided by the position encoder, or when the cigarette making machine is driven by a variable frequency motor, the operating speed of the cigarette making machine can be determined by using the feedback signal (such as the speed signal) provided by the motor driver.

[0038] When the running speed of the cigarette making machine is greater than the preset low-speed running setting value of the cigarette making machine, 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, it represents 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. Specifically, a negative pressure adjustment value matched with the current running speed of the cigarette making machine 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 making machine) * paper cutting wheel negative pressure compensation value, and at least one electric regulating 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 paper cutting wheel negative pressure value is linearly adjusted along with the running speed of the equipment, and finally the ratio of the paper cutting wheel negative pressure value to the current running speed of the cigarette making machine is within the preset threshold, that is, it satisfies the linear relationship.

[0039] Due to the differences in production site and production plan, the operating personnel may frequently adjust the running speed of the equipment, and the equipment does not always run at a fixed speed. Therefore, the mechanism adjusts the negative pressure value in real time to adapt to the change of the running speed of the cigarette making machine, so as to ensure the stability of paper material conveying and the packaging quality during the entire acceleration process from low speed to maximum speed of the equipment.

[0040] The cigarette making machine paper cutting wheel negative pressure adjustment system of the embodiment of the present application 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 tip assembly electric cabinet of the cigarette making machine, the electric regulating valve is installed at the paper cutting wheel negative pressure gas source supply, and the controller is electrically connected with the negative pressure detection device and the electric regulating valve respectively. The negative pressure detection device is used for collecting the analog voltage value of the paper cutting wheel negative pressure in real time and transmitting the collected analog voltage value to the controller. The controller is used for calculating the paper cutting wheel negative pressure value in real time according to the analog voltage value. The running speed of the cigarette making machine is calculated 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, at least one electric regulating valve adjustment instruction is generated and sent to the electric regulating valve in combination with the paper cutting wheel negative pressure value 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, so that the paper cutting wheel negative pressure value is linearly adjusted along with the running speed of the equipment. The electric regulating valve is used for adjusting the opening degree of the paper cutting wheel negative pressure gas source in response to the electric regulating valve adjustment instruction sent by the controller. By responding to the change of production demand and equipment state in real time, the paper cutting wheel negative pressure value is automatically adjusted in time, so as to ensure that the paper closely fits the paper cutting wheel during the cutting process, guarantee the cutting precision and stability, avoid production interruption and waste caused by abnormal negative pressure, reduce the production cost and labor adjustment cost, ensure the continuity of production, improve the production efficiency and quality level of products.

[0041] Optionally, on the basis of the above embodiments, the controller is electrically connected with a pulse sensor on the body of the cigarette forming equipment of the cigarette making machine.

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

[0043] In the embodiment of the application, the pulse sensor refers to a sensor installed on a transmission shaft or a paper cutting wheel or other key components of a paper winding machine to monitor the rotational speed or position of the components. The pulse sensor generates a pulse signal every time the component completes a specific action or rotates by a certain angle.

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

[0045] The serial communication protocol pulse signal refers to a pulse signal transmitted by a serial communication method (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 and acceleration of the equipment.

[0046] Specifically, the controller is directly connected with the pulse sensor installed on the cigarette making machine through an electrical method (such as a wire, a terminal, a connector or an interface), to receive the serial communication protocol pulse signal from the sensor, and the running speed of the cigarette making machine can be calculated in real time by speed = pulse frequency / unit pulse number. Through the accurate pulse signal provided by the pulse sensor, the controller can accurately calculate the real-time speed of the cigarette making machine, so as to realize more precise negative pressure control, reduce production interruptions caused by the mismatch between negative pressure and speed, improve the efficiency, stability and continuity of the entire production process, and thus improve the overall quality of the product.

[0047] Further, on the basis of the above embodiments, the cigarette making machine paper cutting wheel negative pressure adjustment system can further include a knob switch electrically connected with the controller.

[0048] The knob switch is used to be controlled to switch from the closed state to the open state when the cigarette making machine needs to pass through a three-section water-based paper, and to be controlled to switch from the open state to the closed state when the three-section water-based paper is correctly passed through the cigarette making machine.

[0049] The controller is further configured to, when detecting that the rotary knob switch is switched from the closed state to the open state, generate an electrically-operated regulating valve adjustment instruction according to a preset paper feeding negative pressure value and send the instruction to the electrically-operated regulating valve, so that the electrically-operated regulating valve adjusts the opening degree of the paper cutting wheel negative pressure source to be adapted to the paper feeding negative pressure value.

[0050] When detecting that the rotary knob switch is switched from the open state to the closed state, the controller generates an electrically-operated regulating valve adjustment instruction according to a preset low-speed setting paper cutting wheel negative pressure value and sends the instruction to the electrically-operated regulating valve, so that the electrically-operated regulating valve adjusts the opening degree of the paper cutting wheel negative pressure source to be adapted to the low-speed setting paper cutting wheel negative pressure value.

[0051] In the embodiment of the application, the rotary knob switch is a switch electrically connected to the input end of the controller and used for controlling the operation mode of the cigarette making machine. When the cigarette making machine needs to feed in three-section water-based paper or other types of paper materials, the rotary knob switch is switched from the closed state to the open state. When the three-section water-based paper or other types of paper materials are correctly fed into the cigarette making machine, the rotary knob switch is switched from the open state to the closed state.

[0052] The rotary knob switch can be manually opened and closed by a person, or the controller in the system automatically sends a control signal to trigger the opening of the switch to feed in the three-section water-based paper or other types of paper materials when detecting the need to replace the three-section water-based 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, the sensor sends a signal to the controller, indicating that the paper material is used up). After the three-section water-based paper or other types of paper materials are correctly fed into the cigarette making machine, the rotary knob switch is automatically switched to the closed state.

[0053] The three-section water-based paper is a special type of water-based paper, which is composed of three sections and has joints between each section to achieve a specific packaging effect or function. The preset paper feeding negative pressure value can be understood as a negative pressure value preset by the system when feeding in the three-section water-based paper. Negative pressure is used to ensure that the water-based paper is not pulled apart or wrinkled, and can be correctly transported and positioned for subsequent cutting and packaging processes.

[0054] The paper feeding negative pressure value can be understood as the size of the negative pressure used in the cigarette making machine to ensure that the paper material (such as cigarette paper or water-based paper) can be smoothly fed through, correctly spliced, and adsorbed on the paper cutting wheel.

[0055] Specifically, when the controller detects that the knob switch switches from the closed state to the open state, the controller generates an adjustment instruction according to the preset paper feeding negative pressure value and sends it to the electric regulating valve to adjust the opening degree of the paper cutting wheel negative pressure source, so as to adjust the negative pressure of the paper cutting wheel to the appropriate paper feeding negative pressure value, ensuring that the negative pressure is adapted to the preset value. When the knob switch switches 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 and sends it to the electric regulating valve to adjust the opening degree of the paper cutting wheel negative pressure source, so as to adjust the negative pressure of the paper cutting wheel to the low-speed setting value, ensuring that the negative pressure is adapted to the preset value.

[0056] The system can automatically adjust the negative pressure according to different production conditions (such as paper feeding and low-speed operation), enhancing the adaptability and flexibility of the equipment. By precisely controlling the negative pressure during the paper feeding and cigarette rolling of the three-section tipping paper, the system reduces material waste caused by improper operation, optimizes energy use, reduces unnecessary energy consumption, avoids production interruption and waste caused by abnormal negative pressure, reduces production cost and labor adjustment cost, ensures the continuity of production, and improves the production efficiency and quality level of the product.

[0057] Optionally, on the basis of each of the above embodiments, the controller is electrically connected with the normally open contact of the knob switch, and the knob switch is arranged on an operation panel of a filter attaching 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 knob switch, such as switching the knob switch from the closed state to the open state when the cigarette making machine needs to feed the three-section tipping paper, and switching the knob switch from the open state to the closed state when the three-section tipping paper is correctly fed into the cigarette making machine. The controller can directly respond to the state change of the knob switch and execute the corresponding control logic to realize the automatic control of the cigarette making machine.

[0059] By electrically connecting the controller with the normally open contact of the knob switch arranged on the operation panel of the filter attaching electric 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, the control elements are concentrated on the operation panel, which is helpful for centralized monitoring and maintenance, thereby reducing potential misoperation and improving production efficiency. The operator can intervene in the production process in a timely manner, ensuring the flexibility and continuity of the production process, and providing convenience for fault diagnosis and maintenance, further reducing maintenance cost and improving overall production performance.

[0060] Further, on the basis of each of the above embodiments, the paper cutting wheel negative pressure adjustment system of the cigarette making machine can further include a touch screen, and the touch screen is used to set the low-speed running setting value of the cigarette making machine, the low-speed setting paper cutting wheel negative pressure value, the maximum running speed value of the cigarette making machine, and the paper cutting wheel negative pressure compensation value.

[0061] Specifically, in the cigarette cutting wheel negative pressure adjustment system, the touch screen is integrated. The operator can intuitively input and adjust the cigarette machine low-speed running set value, low-speed set cutting wheel negative pressure value, cigarette machine maximum running speed value, cutting wheel negative pressure compensation value and other parameters through the touch screen, reducing the operation error, improving the setting accuracy, thereby realizing the accurate control of the cutting wheel negative pressure value, helping the operator to quickly respond to the changes in production demand, such as adjusting the production speed, switching the product specifications or other preset parameters, further improving the automation level and adaptability of the system, reducing the energy consumption, reducing the material waste, and improving the product quality and production efficiency.

[0062] Optionally, on the basis of the above-mentioned embodiments, the controller is a programmable controller.

[0063] The input pin of the programmable controller is electrically connected with the negative pressure detection device and the knob switch, and the output pin of the programmable controller is electrically connected with the electric regulating valve.

[0064] Specifically, the controller is a programmable controller (PLC). The input pin of the PLC is used to receive signals from the negative pressure detection device and the knob switch. These signals can be analog signals or digital signals to represent the current negative pressure state and the position of the knob switch. The output pin of the PLC is 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 adjust the negative pressure of the cutting wheel.

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

[0066] Embodiment Two

[0067] Figure 2 The flowchart of the cigarette cutting wheel negative pressure adjustment method provided by Embodiment Two of the present application can be applied to automatically adjust the negative pressure value of the cutting wheel in the cigarette machine. The method can be executed by the controller configured in the cigarette cutting wheel negative pressure adjustment system.

[0068] Correspondingly, as shown in Figure 2 the method comprises:

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

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

[0071] S230, when the running speed is greater than the preset low-speed running setting value of the cigarette making machine, at least one electric regulating valve adjustment instruction is generated according to the preset low-speed setting cutting wheel negative pressure value, the maximum running speed setting value of the cigarette making machine and the cutting wheel negative pressure compensation value, and the cutting wheel negative pressure value is sent to the electric regulating valve to make the cutting wheel negative pressure value follow the linear adjustment of the running speed of the equipment.

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

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

[0074] The technical scheme of the embodiment of the application comprises the following steps: acquiring the analog voltage of the negative pressure of the cutting wheel collected by the negative pressure detection device in real time, and calculating the negative pressure value of the cutting wheel according to the analog voltage value in real time; calculating the running speed of the cigarette making machine in real time, and judging whether the running speed is greater than the preset low-speed running setting value of the cigarette making machine in real time; when the running speed is greater than the preset low-speed running setting value of the cigarette making machine, at least one electric regulating valve adjustment instruction is generated according to the preset low-speed setting cutting wheel negative pressure value, the maximum running speed setting value of the cigarette making machine and the cutting wheel negative pressure compensation value, and the electric regulating valve adjustment instruction is sent to the electric regulating valve, so that the cutting wheel negative pressure value is linearly adjusted according to the running speed of the equipment. By responding to the changes in production demand and equipment state in real time, the cutting wheel negative pressure value is automatically adjusted in time, the paper is ensured to be closely attached to the cutting wheel during the cutting process, the cutting precision and stability are ensured, the production interruption and waste caused by abnormal negative pressure are avoided, the production cost and the labor adjustment cost are reduced, the continuity of production is ensured, and the production efficiency and the quality level of the product are improved.

[0076] a serial communication protocol pulse signal acquired in real time from a pulse sensor on the cigarette making machine cigarette forming equipment body;

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

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

[0079] By using the accurate pulse signal provided by the pulse sensor, the controller can accurately calculate the real-time speed of the cigarette making machine, realize more precise negative pressure control, reduce the production interruption caused by the mismatch between the negative pressure and the speed, improve the efficiency, stability and continuity of the entire production process, and thus improve the overall quality of the product.

[0080] Further, on the basis of the above-mentioned embodiments, the cigarette making machine cutting wheel negative pressure adjustment method can further comprise:

[0081] when it is detected that the rotary knob switch is switched from the closed state to the open state, generating an electric regulating valve adjustment instruction according to the preset paper feeding negative pressure value and sending the electric regulating valve adjustment instruction to the electric regulating valve, so that the electric regulating valve adjusts the opening degree of the cutting wheel negative pressure air source to be matched with the paper feeding negative pressure value;

[0082] When the knob switch is detected to switch from the open state to the closed state, an adjustment instruction is generated according to the preset low-speed setting cut paper wheel negative pressure value and sent to the electric regulating valve to adjust the opening degree of the cut paper wheel negative pressure source to adapt to the low-speed setting cut paper wheel negative pressure value.

[0083] Specifically, in the cut paper wheel negative pressure adjustment system of the cigarette making machine, when the knob switch is detected to switch from the closed state to the open state, an adjustment instruction is generated according to the preset paper passing negative pressure value and sent to the electric regulating valve to adjust the opening degree of the cut paper wheel negative pressure source to adjust the negative pressure of the cut paper wheel to the appropriate paper passing negative pressure value, so that the negative pressure is adapted to the preset value. When the knob switch switches from the open state to the closed state, another adjustment instruction is generated according to the preset low-speed setting cut paper wheel negative pressure value and sent to the electric regulating valve to adjust the opening degree of the cut paper wheel negative pressure source to adjust the negative pressure of the cut paper wheel to the low-speed setting value, so that the negative pressure is adapted to the preset value.

[0084] The system can automatically adjust the negative pressure according to different production conditions (such as paper passing and low-speed running), enhance the adaptability and flexibility of the equipment, reduce the material waste caused by improper operation by accurately controlling the paper passing and the negative pressure in the cigarette making process, optimize the use of energy, reduce unnecessary energy consumption, avoid production interruption and waste caused by abnormal negative pressure, reduce production cost and labor adjustment cost, ensure the continuity of production, and improve the production efficiency and quality level of products.

[0085] Further, on the basis of the above-mentioned embodiments, the cut paper wheel negative pressure adjustment method of the cigarette making machine can further include:

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

[0087] Specifically, in the cut paper wheel negative pressure adjustment system of the cigarette making machine, the controller responds to the cigarette making machine low-speed running setting value, low-speed setting cut paper wheel negative pressure value, cigarette making machine maximum running speed value and cut paper wheel negative pressure compensation value 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 state in real time, automatically adjust the cut paper wheel negative pressure value in time, ensure that the paper closely fits the cut paper wheel during cutting, ensure the cutting accuracy and stability, avoid production interruption and waste caused by abnormal negative pressure, reduce production cost and labor adjustment cost, ensure the continuity of production, and improve the production efficiency and quality level of products.

[0088] Specific application scenarios

[0089] Currently, the negative pressure on the cutting wheel of the ZJ17 cigarette making machine is centrally controlled externally. A mechanical negative pressure gauge is installed inside the machine to monitor the negative pressure. However, the negative pressure cannot be automatically adjusted, which can significantly affect the transport of paper materials (such as tipping paper). The cutting wheel uses negative pressure suction to absorb the tipping paper for cutting. Unstable negative pressure can lead to unstable adhesion of the tipping paper to the cutting wheel, resulting in inconsistent lengths and uneven cuts, affecting the appearance of the cigarettes. For example, the tipping paper pieces may be uneven in length, making the packaging unsightly and even affecting the sealing effect. Unstable negative pressure can also affect the adhesion of the tipping paper to the cigarettes. If the negative pressure is too low, the tipping paper may not adhere firmly to the cigarettes and may easily fall off. If the negative pressure is too high, the tipping paper may overstretch or deform, resulting in wrinkles and bubbles after adhesion.

[0090] Because negative pressure is centrally controlled, the startup and operation of different machines will affect the unstable negative pressure. The negative pressure is unstable and cannot be automatically adjusted. Operators need to frequently stop the machine to manually adjust the negative pressure of the paper cutting wheel to ensure cigarette production quality. This not only increases the workload of operators, but also increases equipment downtime, reduces production efficiency, and affects production plans and product output. In particular, for three-section tipping paper products, due to the paper cutting process, if the negative pressure of the paper cutting wheel is too high during the first paper threading and cutting process, it will directly break the paper, preventing the tipping paper from being cut and conveyed, causing production interruption.

[0091] Unstable negative pressure can also cause problems with the cutting and attaching of tipping paper, resulting in significant waste. This waste cannot be reused, resulting in a significant waste of tipping paper material. Furthermore, if negative pressure issues cause the tipping paper to become clogged or entangled within the equipment, this damages the tipping paper and further wastes the material. During cigarette production, problems with the cutting and attaching of tipping paper can also result in incomplete or poorly sealed packaging, exposing tobacco. This exposed tobacco cannot be reused, further wasting tobacco material.

[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 detect the problem of unstable negative pressure in time, which will cause the problem to gradually accumulate during the production process and is not discovered until a large amount of waste is generated or the equipment fails, increasing production costs.

[0093] In order to solve the above problems, the embodiment of the present invention proposes a negative pressure adjustment system for the paper cutting wheel of a cigarette making machine. Figure 3Is a kind of electric regulating valve installation schematic diagram suitable for the embodiment of the present application, Figure 4 Is a kind of electric regulating valve installation scene diagram suitable for the embodiment of the present application, it is corresponding with Figure 3 Corresponding, Figure 5 Is a kind of cigarette machine paper cutting wheel negative pressure adjustment system electrical schematic diagram suitable for the embodiment of the present application, take ZJ17 cigarette machine as an example, the system is composed of siemens PLC, touch screen, electric regulating valve Y1, negative pressure detection device B1 and knob switch S1 etc., wherein, CPU (Central Processing Unit, central processor) in siemens PLC is 224xp model, M in the figure is the common end of analog input module, generally and power negative pole is connected, I is current type analog output, A+ is analog input channel.

[0094] MAX electric cabinet and SE electric cabinet are included in ZJ17 cigarette machine, and various electrical elements and wiring terminals are contained in the electric cabinet.MAX electric cabinet is the electrical control cabinet responsible for cigarette assembly part in cigarette machine, responsible for assembling cigarette and filter tip to form complete cigarette product;SE electric cabinet is the electrical control cabinet responsible for cigarette rolling part in cigarette machine, responsible for rolling tobacco into cigarette and cutting into specified length.

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

[0096] The input terminal I0.0 of the S7-200 PLC is connected to the No. 5 pin of the X24 terminal block of the SE cabinet of the ZJ17 cigarette making machine to collect the SCP (Serial Communication Pulse signal) pulse signal, so as to calculate the running speed of the cigarette making machine. The X24 terminal block is a terminal block row in the ZJ17 cigarette making machine, which is used to connect various signal lines, and the No. 5 pin is the fifth connection point in the X24 terminal block row. Among them, the SCP is a pulse sensor installed on the SE machine body, the faster the device speed, the faster the sensor senses, and 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, wherein the speed is the running speed of the device, the pulse frequency is the frequency of the sensor sensing output, and the 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 operating panel of the MAX cabinet, and the other end of the contact is connected to the 24V positive pole. At the negative pressure air source supply of the paper cutting wheel of the MAX cabinet, an electric regulating valve Y1 is newly added to adjust the negative pressure value of the paper cutting wheel. The positive pole power supply line of the electric regulating valve is connected to the 24V positive pole, the negative pole power supply line is connected to the 24V negative pole, and the data input line is connected to the analog output channel (corresponding to the I channel) of the PLC.

[0098] The PLC adjusts and controls the electric regulating valve to adjust the negative pressure value of the paper cutting wheel to a preset value, which is set by the touch screen installed on the cigarette making machine. The touch screen is powered by 24V positive and 24V negative, and the COM port (Communication Port) is connected to the COM port of the PLC for communication control through the RS485 protocol. Among them, the terminal and pin in the cabinet are determined by the internal connection of the device, and the selection of the terminal and pin is related to the model of the cigarette making machine. Therefore, the connection mode selected is fixed, and the input and output terminals of the PLC can be adjusted and designed according to the specific application requirements.

[0099] When the ZJ17 cigarette making machine is ready for production, the S7-200 PLC analog input channel will collect the analog voltage value of the negative pressure detection B1 to calculate the current negative pressure value of the paper cutting wheel. When the device needs to rethread the three-section water-based paper, the negative pressure value collected by the negative pressure sensor B1 will not be accurate because the air suction hole on the paper cutting wheel has not been fully covered by the water-based paper at this time, which will cause the pressure to be released. At this time, the knob switch S1 can be manually operated, and after the S7-200 PLC input terminal I0.1 receives the knob switch S1 signal, the PLC analog output point controls the electric regulating valve Y1 to act, and runs to the constant small valve opening set on the touch screen, to maintain a small paper threading negative pressure value, to ensure that the water-based paper can be normally conveyed and will not be broken.

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

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

[0102] When the cigarette machine running speed exceeds the low-speed running set value, the electric regulating valve Y1 is controlled to act according to the screen set parameters, so that the paper cutter wheel negative pressure value automatically increases with the running speed of the equipment, that is, when the equipment running speed is lower than the low-speed running set value, the system will control the negative pressure to be the low-speed set paper cutter wheel negative pressure value to ensure the stability of the paper material transportation; when the equipment running speed exceeds the low-speed running set value, and the calculated paper cutter wheel negative pressure value and the current cigarette machine running speed exceed the pre-set threshold value, it represents that the current paper cutter wheel negative pressure value and the current cigarette machine running speed do not match, and the paper cutter wheel negative pressure value needs to be adjusted. The system will adjust the current negative pressure according to the following formula: negative pressure adjustment value = low-speed set paper cutter wheel negative pressure value + (maximum running speed set value - current speed) x paper cutter wheel negative pressure compensation value, to realize the linear rise of the 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 within the pre-set variable range. Since the operating personnel may frequently adjust the equipment running speed, and the equipment does not always run at a fixed speed, this mechanism adjusts the negative pressure value in real time to adapt to the change of the running speed, so as to ensure the stability of the paper material transportation and the packaging quality during the entire acceleration process from low speed to maximum speed of the equipment.

[0103] The cigarette machine paper cutting wheel negative pressure adjustment system can effectively control the negative pressure of the tipping paper cutting wheel, automatically adjust the negative pressure according to the running speed of the equipment, and ensure the stable conveying of the tipping paper. The automatic adjustment function can adjust the negative pressure in real time according to the production requirements and the equipment state without manual intervention, thereby reducing the adjustment time of the equipment and improving the production efficiency. In addition, the system can adapt to the changes of the raw material characteristics and the production speed, so that the paper can closely fit the cutting wheel during the cutting process, ensuring the accuracy and consistency of the cutting, and ensuring the appearance quality and size precision of the cigarettes. For example, in the production of slim cigarettes or special specification cigarettes, accurate negative pressure control can better meet the quality requirements of the products. By monitoring the negative pressure value of the cutting wheel in real time, the system can adjust in time once the negative pressure is found to be abnormal, avoiding the problems of irregular paper cutting and paper jam caused by negative pressure problems, thereby avoiding the generation of a large amount of waste products, ensuring the stability and efficiency of the paper cutting process, reducing the waste of raw materials and production interruption, reducing the waste rate and production cost, and improving the effective operation time of the equipment, the qualified rate of the products and the overall quality level.
