Description

Technical Field

[0001] This invention relates to the field of flame arrestor core production equipment technology, specifically a voltage-stabilized and self-regulating flame arrestor core winding machine. Background Technology

[0002] In industrial production and fire safety, flame arrestor cores are a critical component, their performance directly affecting the fire safety of equipment. Flame arrestor cores are typically made from specific materials through a meticulous winding process to ensure excellent flame-arresting performance and stability. With increasingly stringent fire safety requirements across industries, higher demands are being placed on the quality and production efficiency of flame arrestor cores. Traditional flame arrestor core winding methods rely primarily on manual operation or simple mechanical devices, resulting in low efficiency and inconsistent quality. However, with continuous technological advancements and the widespread application of automated equipment in industrial production, developing a voltage-stabilized, self-regulating flame arrestor core winding machine has become an inevitable trend to meet market demands.

[0003] According to Chinese Patent No. CN 112139816 A, a corrugated plate flame arrester filter element winding device includes a worktable and a main turntable mounted on the worktable via bearings, and two freely rotatable raw material turntables. A damping adjustment mechanism and multiple guide rollers are arranged between the two raw material turntables and the main turntable. A positioning mechanism is located at the center of the main turntable, and a clamping mechanism is installed around the main turntable. The main turntable is driven by a servo motor with a reducer. A control box is installed below the worktable, containing a motion controller. During the winding process, flat steel strip coils are placed on one raw material turntable, and corrugated steel strip coils are placed on the other. The flat steel strip is fed into the main turntable after passing through the damping adjustment mechanism and several guide rollers, while the corrugated steel strip is fed into the main turntable after passing through several guide rollers. This flame arrester filter element winding device has a novel structure, low cost, and high degree of automation, which can improve the production efficiency and quality of filter element discs and can handle the winding production of filter element discs of various specifications.

[0004] The existing technology has the following problems in practical use: 1. While some existing mechanical winding equipment improves production efficiency to a certain extent, it often lacks automatic adjustment functions. During the winding process, tension is prone to fluctuation due to changes in material properties, thickness, and other factors, as well as various disturbances during equipment operation. Equipment lacking automatic adjustment functions after detection, and whose detection and control systems cannot adjust the tension in time, may lead to problems such as loose, overly tight, or uneven flame arrestor cores, affecting product quality; 2. During the winding process, abnormal situations such as material breakage and overstretching may occur. Existing equipment is insufficient to handle these abnormalities and often requires manual intervention due to its inability to analyze them quickly. This not only increases production costs but also reduces production efficiency. For example, if the equipment does not automatically stop operating when material breaks, it may lead to further material waste and equipment damage.

[0005] Therefore, a voltage-stabilized, self-regulating flame-retardant core winding machine is needed to solve the above problems. Summary of the Invention

[0006] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a voltage-stabilized, self-regulating flame-arresting core winding machine. This solves the problem that while some existing mechanical winding equipment improves production efficiency to a certain extent, it often lacks automatic adjustment capabilities. During the winding process, tension is prone to fluctuations due to changes in material properties, thickness, and various disturbances during equipment operation. Equipment lacking automatic adjustment capabilities after detection, and whose detection and control systems cannot adjust tension in a timely manner, may result in problems such as loose, overly tight, or uneven flame-arresting cores, affecting product quality.

[0007] Technical solution To achieve the above objectives, the present invention provides the following technical solution: a pressure-stabilized and self-regulating flame-retardant core winding machine, comprising a machine base and a control terminal. The control terminal is embedded in the front of the machine base. A first-type feeding tray is installed on one side of the top of the machine base, and a second-type feeding tray is installed on the top of the machine base near the first-type feeding tray. Flame-retardant core raw materials are wound on the outer top of both the first-type and second-type feeding trays. A main control system is embedded inside the control terminal. The main control system includes a tension monitoring and adjustment subsystem, an anomaly detection and handling subsystem, a human-machine interaction subsystem, and a data storage and management subsystem.

[0008] Preferably, a winding device is connected to the other side of the top of the machine base via a drive mechanism. The winding device is driven by a motor. A first winding head is threadedly connected to one side of the top of the winding device, and a second winding head is threadedly connected to the other side of the top of the winding device. The first and second winding heads on the winding device are combined to wind the fire-retardant core material wound from both sides together, that is, one side is smooth and the other side is corrugated.

[0009] Preferably, a flattening strip is movably connected to the top of the machine near the reel, with one end of the flattening strip positioned high in the middle of the reel. The height of the flattening strip is greater than the height of the winding device. Both the winding device and the flattening strip are elongated strips. The flattening strip is used to smooth the flame-retardant core wound onto the reel by the winding device.

[0010] Preferably, an installation box is installed in the middle of the top of the machine, and a slit is opened on the top of one side of the installation box. Corrugated pressing heads are installed on both sides of the slit, and the corrugated pressing heads are corrugated on the outside.

[0011] Preferably, a type of winding wheel is installed on both the front and back of the slit of the mounting box. An adjustment groove is provided on the top of the machine near the mounting box. There are two sets of adjustment grooves, each equipped with a movable winding wheel. When the equipment is first started, the rear end of the adjustment groove begins winding. Without this part, the corrugated steel strip would be pulled during rear-end winding, causing deformation. An elastic rope inside the adjustment groove pulls the movable winding wheel. When the rear end begins winding at startup, the movable winding wheel can be pulled along the groove to the right, thus buffering the deformation of the corrugated steel strip.

[0012] Preferably, five sets of two types of winding wheels are installed on the top of the machine near the front of the two-type feeding tray. When the raw material on the two-type feeding tray is pulled, it passes through the five sets of two-type winding wheels on one side in sequence, and then is wound up by the second winding head. The raw material on the one-type feeding tray on the other side passes through the one-type winding wheel, and after being pressed into a corrugated shape by the internal corrugated pressing head through the slit, it first passes through the movable winding wheel, and then comes to the first winding head for winding.

[0013] Preferably, a data receiver is electrically connected to one side of the front of the control terminal, and a data transmitter is electrically connected to the other side of the front of the control terminal.

[0014] Preferably, tension sensors, material fracture sensors, and overstretch sensors are installed on both the front and back of the top of the machine tool.

[0015] Preferably, the tension sensor transmits the detected tension data to the tension monitoring and adjustment subsystem in the main control system within the control terminal via a data transmitter; the material fracture sensor transmits the detected material fracture signal to the anomaly detection and processing subsystem in the main control system within the control terminal via a data transmitter; and the overstretching sensor transmits the detected overstretching signal to the anomaly detection and processing subsystem in the main control system within the control terminal via a data transmitter.

[0016] Beneficial effects This invention provides a voltage-stabilized, self-regulating flame-retardant core winding machine. It has the following beneficial effects: 1. The equipment in this invention automates the winding of the flame-arresting core, greatly reducing manual intervention and thus significantly improving production efficiency. Simultaneously, through a precise tension monitoring and adjustment subsystem and an anomaly detection and handling subsystem, various parameters during the winding process can be adjusted in real time, ensuring stable winding of the flame-arresting core under different material and thickness conditions. This effectively improves product quality stability and avoids quality fluctuations caused by manual operation.

[0017] 2. The equipment in this invention is equipped with advanced material fracture sensors and overstretch sensors, which can detect abnormalities in the winding process in a timely manner. When problems such as material fracture or overstretching occur, the abnormality detection and handling subsystem can react quickly and take corresponding emergency measures, such as stopping the winding machine motor and adjusting the position of the winding wheel, to prevent the production failure from escalating further, reduce material waste and equipment damage, and improve the safety and reliability of production.

[0018] 3. The human-machine interaction subsystem and data storage and management subsystem of this invention can store and manage various data during the operation of the winding machine, such as tension data, abnormal situation records, and parameter settings. Operators can understand the equipment's operating status and production efficiency by querying historical data, providing strong support for production management. At the same time, this data can also provide a basis for equipment optimization and improvement. Through data analysis and utilization, the production process can be continuously optimized, and product quality and production efficiency can be improved. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific Implementation Example 1: like Figure 1-6 As shown, a voltage-stabilized and self-regulating flame-retardant core winding machine includes a machine base 1 and a control terminal 8. The control terminal 8 is embedded on the front of the machine base 1. A first-type feeding tray 2 is installed on one side of the top of the machine base 1. A second-type feeding tray 3 is installed on the top of the machine base 1 near the first-type feeding tray 2. Flame-retardant core raw material 4 is wound on the outer top of both the first-type feeding tray 2 and the second-type feeding tray 3.

[0023] On the other side of the top of the machine base 1, a winding head 11 is connected to a drive mechanism. The winding head 11 is driven by a motor. A first winding head 10 is threadedly connected to one side of the top of the winding head 11, and a second winding head 12 is threadedly connected to the other side of the top of the winding head 11. The first winding head 10 and the second winding head 12 on the winding head 11 are used together to wind the fire-retardant core material 4 wound from both sides together, that is, one side is smooth and the other side is corrugated.

[0024] A flattening strip 7 is movably connected to the top of the machine base 1 near the side of the coil 9. One end of the flattening strip 7 is located at a high position in the middle of the coil 9. The height of the flattening strip 7 is higher than the height of the coiler 11. Both the coiler 11 and the flattening strip 7 are elongated strips. The flattening strip 7 is used to smooth the flame arrestor core wound by the coiler 11 on the coil 9.

[0025] A mounting box 15 is installed at the center of the top of the machine base 1. A slit 5 is opened on the top of one side of the mounting box 15. Corrugated pressing heads 17 are installed on both sides inside the slit 5. The corrugated pressing heads 17 are corrugated on the outside.

[0026] A type of winding wheel 6 is installed on both the front and back of the slit 5 of the mounting box 15. An adjustment groove 14 is provided on the top of the machine base 1 near the mounting box 15. There are two sets of adjustment grooves 14, and each adjustment groove 14 is equipped with a movable winding wheel 13. When the equipment is first started, the rear end of the adjustment groove 14 is wound up. Without this part, when the rear end is wound up, the steel strip that has been processed into corrugations will be pulled by the rear end, and the corrugations will be deformed. There is an elastic rope in the adjustment groove 14 that pulls the movable winding wheel 13. When the equipment is first started and the rear end begins to wind up, the movable winding wheel 13 can be pulled along the groove to the right, thereby buffering the deformation of the textile corrugated steel strip.

[0027] Five sets of two types of winding wheels 16 are installed on the top of the machine 1 near the front of the two-type feeding tray 3. When the raw material on the two-type feeding tray 3 is pulled, it will pass through the five sets of two-type winding wheels 16 on one side in sequence, and then be wound up by the second winding head 11. The raw material on the other side of the first-type feeding tray 2 passes through the first-type winding wheel 6, and after being pressed into a corrugated shape by the corrugated pressing head 17 inside the slit 5, it will first pass through the movable winding wheel 13, and then come to the first winding head 11 for winding.

[0028] When using the entire equipment, firstly, the flame-arresting core material is neatly and securely wound onto the first-type discharge tray 2 and the second-type discharge tray 3. These two discharge trays are installed on one side of the top of the machine base 1 for material release. Next, check the connection between the winding device 11 and the first winding head 10 and the second winding head 12. The winding device 11 is driven by a motor and located on the other side of the top of the machine base 1, used to wind the material on both sides into a flame-arresting core with one smooth surface and one corrugated surface. Then, confirm the position and state of the flattening strip 7. It is movably connected to the top of the machine base 1 near the winding tray 9 and is higher than the winding device 11, used to smooth the flame-arresting core. Then check the mounting box 15, the corrugated pressing head 17, and the first-type winding wheel 6. The mounting box 15 is located in the middle of the top of the machine base 1. The corrugated pressing head 17 is located in the slit 5 to press the material into a corrugated shape. There is a first-type winding wheel 6 on both sides of the slit 5 to guide the material direction. Simultaneously confirm the status of the adjusting groove 14 and the movable winding wheel 13. The adjusting groove 14 is located on the top of the machine base 1 near the mounting box 15, and contains the movable winding wheel 13 connected by an elastic rope. It can buffer and prevent the corrugated steel strip from deforming when the equipment is started and the winding is completed. Finally, check the status of the second-class winding wheels 16. Five sets of second-class winding wheels 16 are installed on the top of the machine base 1 near the front of the second-class unloading tray 3. They are used to guide the raw material on the second-class unloading tray 3. After the equipment is started, the motor drives the winding machine 11 to rotate through the control terminal 8. Under the action of tension, the raw material on the second-class unloading tray 3 passes through the five sets of second-class winding wheels 16 in sequence and is wound up by the second winding head 12 at the top of the winding machine 11. Simultaneously, the raw material on the first type of feeding tray 2 enters the slot 5 of the mounting box 15 through the first type of winding wheel 6, and is pressed into a corrugated shape by the corrugated pressing head 17. Then it passes through the movable winding wheel 13 (when the equipment starts and the rear winding is completed, the movable winding wheel 13 is pulled to the right along the adjusting groove 14 to provide a buffering effect), and then comes to the first winding head 11. The first winding head 10 and the second winding head 12 roll the raw material on both sides together to form a flame-arresting core wound on the winding tray 9. The flattening strip 7 continuously smooths the surface to ensure the flatness of the flame-arresting core. It should be noted that the winding routes of the two sets of raw materials in this equipment are attached. Figure 2 There is an illustration in the image.

[0029] It should be noted that the display screen of control terminal 8 can be a touch screen design, which facilitates parameter setting and operation control by operators. The touch screen should have good response speed and accuracy to ensure accurate and convenient operation.

[0030] Control terminal 8 can be equipped with an alarm device. When abnormal conditions occur in the equipment, such as excessive tension or material breakage, the alarm device will issue an audible and visual alarm to remind the operator to take timely action. The volume and light intensity of the alarm device should be sufficiently noticeable so that the operator can detect it promptly even in noisy environments.

[0031] Control terminal 8 can also be connected to a remote monitoring system, allowing managers to monitor the equipment's operating status and production progress in real time. The remote monitoring system can use a wireless or wired network connection to achieve data transmission and sharing. Specific Implementation Example 2: like Figure 1-6 As shown, based on the content of Specific Embodiment 1, the following content is further disclosed: A data receiver 21 is electrically connected to one side of the front of the control terminal 8, and a data transmitter 22 is electrically connected to the other side of the front of the control terminal 8. Tension sensors 18, material fracture sensors 19, and overstretch sensors 20 are installed on the front and back of the top of the machine base 1. Tension sensors 18 transmit the detected tension data to the tension monitoring and adjustment subsystem in the main control system of the control terminal 8 through the data transmitter 22. Material fracture sensors 19 transmit the detected material fracture signal to the anomaly detection and processing subsystem in the main control system of the control terminal 8 through the data transmitter 22. Overstretch sensors 20 transmit the detected overstretch signal to the anomaly detection and processing subsystem in the main control system of the control terminal 8 through the data transmitter 22.

[0033] In actual use of this equipment, a tension sensor 18 is installed on the raw material path between the first type of feeding disc 2 and the first type of winding wheel 6 to detect the initial tension of the raw material released from the first type of feeding disc. A tension sensor 18 is installed between the second type of feeding disc 3 and the second type of winding wheel 16 to detect the initial tension of the raw material released from the second type of feeding disc. A tension sensor 18 is installed between the movable winding wheel 13 and the first winding head 10 to detect the tension of the raw material after corrugation treatment. A tension sensor 18 is installed between the winding device 11 and the flattening strip 7 to detect the tension of the raw material during final winding.

[0034] The ZX-200 high-precision tension sensor can be selected. This sensor features a wide measurement range, high accuracy, and good stability, enabling accurate measurement of tension changes in the flame arrestor core material at different locations. After receiving data from the tension sensor 18, the tension monitoring and adjustment subsystem first determines the ideal tension range. For flame arrestor core materials of different materials and thicknesses, a correlation between material properties and the ideal tension range is established through extensive experiments and data analysis. For example, for a specific material and thickness of flame arrestor core, based on its physical properties and past production experience, the ideal tension range is determined as follows: to This range can be dynamically adjusted according to actual conditions to adapt to different production conditions and requirements. Then, the tension deviation value is calculated. After receiving the real-time tension data T_real, the tension deviation value is calculated as follows: 2; This deviation value reflects the degree of deviation between the real-time tension and the ideal tension. The degree of deviation is then assessed, and an allowable deviation value is set. It is used to determine whether the tension needs to be adjusted.

[0035] If | |> ; If the tension exceeds the acceptable range, adjustment is required. To more accurately determine the adjustment range and direction, a weighting coefficient can be introduced. Based on the importance of the tension sensors at different locations throughout the winding process, a weighting coefficient K is assigned to each sensor. For example, the tension sensor 18, located closer to the winding unit 11, may have a greater impact on the final winding quality, and therefore can be assigned a larger weighting coefficient. Adjustment range A = K * By introducing weighting coefficients, tension adjustments can be made more specifically.

[0036] Then, based on the calculated tension deviation value and weighted adjustment range, the current tension state is determined. If A > 0, the tension is too high; if A < 0, the tension is too low. When the tension is too high, it needs to be reduced. This can be achieved by reducing the speed of the winding machine 11 motor to decrease the winding speed of the raw material, thereby reducing the tension. Alternatively, the winding wheel can be moved slightly outward to increase the material's transmission path length, further reducing the tension. The specific adjustment range can be dynamically adjusted according to the actual situation. For example, the motor speed can be reduced by a certain percentage, or the winding wheel can be moved a certain distance. When the tension is too low, it needs to be increased. Conversely, increasing the winding speed of the raw material can be achieved by increasing the speed of the winding machine motor to increase the tension. Alternatively, the winding wheel can be moved slightly inward to decrease the material's transmission path length, further increasing the tension. The adjustment range can also be dynamically adjusted according to the actual situation. After determining the adjustment decision, the tension monitoring and adjustment subsystem transmits the adjustment command to the corresponding equipment through the data transmitter in the control terminal. Specifically, if adjusting the motor speed is required, the command will be transmitted to the motor driver control module; if adjusting the position of the winding wheel is required, the command will be transmitted to the winding wheel position adjustment module. Upon receiving the command to adjust the motor speed, the motor driver control module adjusts the speed of the winding machine motor according to the parameters in the command. For example, if the command requires reducing the motor speed, the motor driver control module will reduce the motor's power supply voltage or frequency, thereby reducing the motor speed. Upon receiving the command to adjust the winding wheel position, the winding wheel position adjustment module adjusts the position of the winding wheel through a mechanical device. For example, if the command requires moving the winding wheel outward, the winding wheel position adjustment module will activate the corresponding motor or cylinder to push the winding wheel outward a certain distance.

[0037] Based on the above, the following supplementary points are made regarding tension calculation: Tension calculation section: When determining the ideal tension range, specific experimental methods and data analysis procedures can be provided. For example, "By conducting multiple tensile tests on flame-arresting core materials of different materials and thicknesses, measuring their deformation and performance indicators under different tensions, and combining previous production experience, the ideal tension range is determined using statistical analysis methods. For a flame-arresting core of a specific material and thickness, assuming that data such as its fracture strength and elastic modulus under different tensions are obtained through experiments, the ideal tension range is determined through regression analysis as follows:" *Material property parameters + b, *Material property parameters + d, where a, b, c, and d are coefficients determined experimentally. Material property parameters may include the material's density, hardness, etc. The calculation of tension deviation can be further refined. For example, "when calculating the tension deviation value, not only should the difference between the average value of the real-time tension and the ideal tension be considered, but also the rate of change of the real-time tension. Let the real-time tension be..." The time is , The tension deviation value is: 2+ ; in These are coefficients determined based on experience. This represents the rate of change of tension in real time. This allows for a more comprehensive reflection of the degree of tension deviation and its changing trend, improving the accuracy and timeliness of tension adjustment. When introducing weighting coefficients, specific calculation methods and examples can be provided. For example, "Based on the importance of tension sensors at different locations throughout the winding process, a weighting coefficient K is assigned to each sensor. Importance can be determined by evaluating the impact of tension at different locations on the final winding quality. Assuming the influence weight of the tension sensor closest to the winding coil on the final winding quality is w1, and the influence weights of tension sensors at other locations are w2, w3, and w4 respectively, then the weighting coefficient K1 = w1." (w1+w2+w3+w4), K2=w2 (w1+w2+w3+w4), and so on. For example, for a specific flame-retardant core winding process, after evaluation, it is determined that the influence weight of the tension sensor near the winding machine on the final winding quality is 0.5, and the influence weights of the tension sensors at the other three locations are 0.2, 0.2, and 0.1, respectively. Then, the weighting coefficient K1 of the tension sensor near the winding machine is 0.5. (0.5 + 0.2 + 0.2 + 0.1) = 0.5, and the weighting coefficients for the other three positions are K2 = 0.2. 1=0.2, K3=0.2 1=0.2, K4=0.1 1 = 0.1.

[0038] The adjustment range A = K1*ΔT1 + K2*ΔT2 + K3*ΔT3 + K4*ΔT4, where ΔT1, ΔT2, ΔT3, and ΔT4 are the tension deviation values ​​at the four positions, respectively. III. Adjustment of Decision-Making Section Regarding methods for reducing tension, the specific percentage reduction in motor speed and the calculation method for the distance the material wheel moves can be explained in detail. For example, "When the tension is too high and needs to be reduced, the percentage reduction in motor speed can be determined based on the tension deviation value and the weighted adjustment range. Assuming the initial motor speed is n0 and the tension deviation value is..." The weighted adjustment range is A, and the motor speed reduction ratio is r. Then r = α * |A| , where α is a coefficient determined empirically. The distance the wheel moves can be calculated based on parameters such as tension deviation and the elastic modulus of the raw material.

[0039] Assuming the initial position of the winding wheel is x0, the elastic modulus of the raw material is E, and the tension deviation is... The distance the winding wheel travels is ,but =β* , where β is a coefficient determined empirically. Similarly, for increasing tension, calculation methods for the percentage increase in motor speed and the distance the material-winding wheel travels can be provided. For example, "When the tension is too low and needs to be increased, the percentage increase in motor speed can be determined based on the tension deviation value and the weighted adjustment range. Assuming the initial motor speed is n0 and the tension deviation value is..." The weighted adjustment range is A, and the motor speed is increased by a percentage of r. Then r = γ * A / Where γ is a coefficient determined empirically. The distance the winding wheel moves can be calculated based on parameters such as the tension deviation value and the elastic modulus of the raw material. Assuming the initial position of the winding wheel is x0, the elastic modulus of the raw material is E, and the tension deviation value is... The distance the winding wheel travels is , but =δ* , where δ is a coefficient determined empirically. Specific Implementation Example 3: like Figure 1-6 As shown, based on the content of Specific Embodiment 1 and Specific Embodiment 2, the following content is further disclosed: The following is a detailed working process of the anomaly detection and handling subsystem: I. Data Collection and Preliminary Processing Material fracture sensor 19 and overstretch sensor 20 are distributed along the entire raw material transport path, including locations such as the first type of winding wheel 6, the second type of winding wheel 16, the movable winding wheel 13, and near the winding machine 11, to collect data related to the material state in real time.

[0040] After the data transmitter 22 transmits the data collected by the sensor to the control terminal 8, it first performs preliminary data processing and filtering to remove possible interference signals and ensure the accuracy and reliability of the data.

[0041] II. Data Analysis Methods Material fracture detection and analysis: Material fracture sensors 19 typically employ principles such as resistance change and optical detection. When a material fractures, the sensor detects a significant signal change. For example, a resistive material fracture sensor exists in a specific resistive state when the material is intact; however, the resistance value changes abruptly after the material fractures.

[0042] The analysis method can set a resistance change threshold R_threshold. When the resistance change ΔR detected by the sensor exceeds this threshold, i.e. ΔR>R_threshold, it is judged that the material is fractured.

[0043] Overstretching detection and analysis: Overstretch sensors 20 typically determine whether overstretching has occurred by measuring changes in the strain or tension of a material. For example, strain gauge sensors can be used; when a material is subjected to overstretching, the strain gauge will generate a corresponding strain signal. Analysis methods can then determine a maximum allowable strain value based on the material and thickness of the flame-retardant core. _ or range of tension variation .

[0044] When the strain detected by the sensor Exceeding the maximum strain value, Right now > _ , Or tension change Exceeding the range of tension variation, Right now When this occurs, it is judged as overstretching.

[0045] III. Judgment and Adjustment Decisions Material fracture treatment: When material breakage is detected, emergency measures are taken immediately. First, the anomaly detection and handling subsystem sends a stop command to the coiler motor to prevent further material loss and equipment damage.

[0046] Simultaneously, an alarm is issued to notify the operator to handle the situation. The location of the material fracture and related information can be displayed through the human-machine interface on the control terminal 8, allowing the operator to quickly locate and resolve the problem.

[0047] While waiting for operators to handle the situation, the system can record information such as the time and location of material breakage for subsequent analysis and improvement of the production process.

[0048] Overstretching treatment: When overstretching is detected, appropriate adjustment measures should be taken. First, reduce the speed of the winding machine motor to decrease the winding speed, thereby reducing the tension of the material and preventing further overstretching.

[0049] Depending on the actual situation, the position of the winding wheel can be adjusted appropriately to increase the length of the material transmission path and alleviate tension. For example, if overstretching occurs between the movable winding wheel 13 and the first winding head 10, the movable winding wheel 13 can be moved a certain distance away from the first winding head 10.

[0050] Continuously monitor the material's condition until the tension returns to the normal range. If the overstretching problem persists after adjustments, issue another alarm to notify operators for further inspection and handling.

[0051] IV. Signal Transmission and Equipment Adjustment Signal transmission path: In the event of material fracture, the anomaly detection and handling subsystem transmits a command to stop the winding machine motor to the motor driver control module via the data transmitter 22 in the control terminal 8, and simultaneously transmits an alarm signal to the human-machine interface subsystem so that the alarm information can be displayed on the human-machine interface.

[0052] In the case of overstretching, commands to reduce motor speed and adjust the position of the winding wheel are transmitted to the motor driver control module and the winding wheel position adjustment module, respectively.

[0053] Equipment adjustment process: Upon receiving a command to stop the motor, the motor driver control module immediately cuts off the power supply to the coiler motor, causing it to stop rotating. For commands to reduce the motor speed, the speed is reduced by adjusting the motor's power supply voltage or frequency.

[0054] After receiving the instruction to adjust the position of the winding wheel, the winding wheel position adjustment module pushes the winding wheel to the designated position through mechanical devices such as motors and cylinders.

[0055] Through the above process, the anomaly detection and handling subsystem can detect abnormalities in the winding process in a timely manner and take effective measures to handle them, prevent production failures, and ensure the stable operation of the flame arrestor core winding machine. Specific Implementation Example 4: like Figure 1-6As shown in Specific Embodiment 1, the following further details are disclosed: The human-machine interaction subsystem and the data storage and management subsystem play crucial roles in the voltage-stabilized, self-regulating flame-arresting core winding machine. The human-machine interaction subsystem includes a display module that displays the winding machine's operating status, tension values, and abnormal conditions in real time on the control terminal screen, allowing operators to intuitively understand the equipment's operation and promptly identify and address problems. The parameter setting module allows operators to set parameters such as tension range, motor speed, and winding wheel position on the control terminal according to different flame-arresting core materials and thicknesses to achieve optimal winding results. The operation control module provides operation buttons and an interface, facilitating operators to start and stop the winding machine and adjust the operating mode. Manual control is also available to meet different production needs. The data storage and management subsystem's data storage module stores various data such as tension data, abnormal condition records, and parameter settings in a local or remote database, providing a basis for equipment optimization and improvement. The data management module manages and maintains the stored data, including backup, recovery, and query functions. Operators can use this module to query historical data, understand equipment operation status and production efficiency, and provide strong support for production management.
