Description

Technical Field

[0001] This application relates to the field of roll forming technology, and in particular to an adjustment device for a roller frame, a roller frame, and an adjustment method. Background Technology

[0002] As an important part of the metal processing industry, the roll forming industry has seen continuous growth in market demand, thanks to the following factors: First, the expansion of downstream application areas, such as new energy vehicles and high-end equipment manufacturing, which have led to an increasing demand for roll forming lines; second, the driving force of technological innovation, with continuous progress in roll forming technology improving product performance and precision to meet the needs of high-end application areas; and third, the improvement of intelligence and automation levels, with roll forming machines developing towards intelligentization.

[0003] As the core component of a roll forming line, the forming roller assembly requires meticulous technical refinement. The roller frame, as a crucial support for the forming roller assembly, has stringent requirements regarding strength, toughness, and stability. Currently, the adjustment technology for the roller frame primarily involves simultaneously rotating adjusting screws at both ends. This causes the adjusting screws to move a slider connected to the shaft up and down, thereby altering the distance between the upper and lower roller shafts to match rollers of different sizes.

[0004] The current adjustment method has certain drawbacks: the rollers are in constant contact with metal materials, especially when processing thick materials and high-strength steel, which can easily cause wear and high maintenance costs. Therefore, since the roller frame is adjusted manually by visual inspection and scale lines, and both ends are adjusted simultaneously, uneven adjustment pressure will cause the rollers to be slightly skewed, which will accelerate the wear of the rollers and reduce the stability of the forming process. Summary of the Invention

[0005] The purpose of this application is to provide an adjustment device, roller frame, and adjustment method for a roller frame, so as to achieve precise and efficient adjustment of the roller frame.

[0006] To achieve the above objectives, this application provides the following solution: In a first aspect, this application provides an adjustment device for a roller frame, the adjustment device being used for the roller frame, the roller adjustment device being disposed at both ends of an upper roller shaft in the roller frame; The roller adjusting device includes: Adjusting screw, screw pressure plate, bracket slider and pressure detection device; The bottom of the bracket slider is fixed on the upper roller shaft, and a pressure detection device is provided on the top; the screw plate is fixed on the top of the pressure detection device, the lower end of the adjusting screw passes through the screw plate and is engaged with the screw plate, and the end of the adjusting screw contacts the pressure detection device; The adjusting screw is used to move up and down under the applied adjusting pressure, thereby driving the screw plate to move up and down, causing the bracket slider to move up and down, so as to displace the upper roller shaft and change the distance between the upper and lower roller shafts. The pressure sensor is used to detect the applied regulating pressure value, which is used to indicate the magnitude of the applied regulating pressure.

[0009] Optionally, in the roller frame adjustment device provided in this application, a second slot is provided on the bottom side of the U-shaped notch, and an annular scale is fitted on one end of the adjustment screw. The scale is engaged in the second slot, so that the adjustment screw drives the screw pressure plate to move.

[0010] Optionally, in the roller frame adjustment device provided in this application, the two sides of the U-shaped notch of the screw pressure plate are fixed to the top of the pressure detection device by screws.

[0011] Optionally, the roller frame adjustment device provided in this application includes a housing, a pressure sensor, a processor, and an alerting device. The reminder device includes an indicator light and / or a loudspeaker mounted on the outer wall of the housing; The processor is used to receive electrical signals from the pressure sensor and control the reminder device to perform adjustment reminder operations based on the pressure adjustment value corresponding to the electrical signal and the set adjustment pressure threshold.

[0012] Optionally, in the roller frame adjustment device provided in this application, the other end of the adjustment screw passes through a through hole at the top of the bracket; A screw sleeve assembly is provided on the protruding end of the adjusting screw, and adjusting pressure is applied by rotating the screw sleeve assembly.

[0013] Secondly, this application provides a roller frame, which includes two supports, an upper roller and a lower roller disposed between the two supports, and roller adjustment devices as described in the first aspect disposed at both ends of the upper roller shaft.

[0014] Thirdly, this application provides a pressure adjustment method for a roller frame, the method being used for the roller frame as described in the second aspect, the method comprising: A first pressure value and a second pressure value are obtained. The first pressure value is acquired by a first pressure detection device located at one end of the upper roller shaft, and the second pressure value is acquired by a second pressure detection device located at the other end of the upper roller shaft. Compare the magnitudes of the first pressure value and the second pressure value, as well as the set pressure threshold value; Based on the comparison results, a reminder instruction is generated, which is used to instruct the reminder mechanism to perform an adjustment reminder operation.

[0015] Optionally, in the pressure adjustment method for the roller frame provided in this application, generating a reminder instruction based on the comparison result includes: If the first pressure value exceeds the pressure threshold, a first reminder instruction is generated, which instructs the reminder device of the first pressure detection device to perform a reminder operation.

By installing roller adjustment devices at both ends of the upper roller shaft of the roller frame, the pressure during the pressure adjustment process is monitored in real time, improving adjustment accuracy and efficiency. Specifically, the roller adjustment device has a support slider whose bottom is fixed to the upper roller shaft, and a pressure detection device at its top. The lower end of the adjustment screw passes through a screw pressure plate fixed to the top of the pressure detection device and contacts the pressure sensor. Thus, when the adjustment screw moves up and down under the applied adjustment pressure, it drives the screw pressure plate to move up and down, thereby driving the support slider to move up and down, ultimately causing displacement of the upper roller shaft and changing the distance between the upper and lower roller shafts. During the adjustment process, the pressure detection device can monitor the applied adjustment pressure value in real time to indicate the magnitude of the subsequent adjustment pressure, improving adjustment accuracy and efficiency, reducing manual time, and ultimately achieving roller position adjustment. This ensures that the adjustment amount at both ends of the upper roller shaft remains consistent, thus maintaining a consistent distance between the upper and lower rollers. This reduces roller wear during subsequent operations and improves the stability of the roller pressing production line. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] It is understandable that in the roll forming industry, the roll forming machine is an important piece of equipment, and the core structure is the forming roller assembly. The roller frame, as the supporting structure of the forming roller assembly, is used to install, fix, and adjust the upper and lower rollers to achieve various processes such as continuous cold bending of sheet metal.

[0022] like Figure 1 As shown, a standard roller frame is typically a symmetrical / vertical frame structure, with one set of frames corresponding to one forming pass. It mainly consists of four parts: the frame body (support and base), a rigid structure that supports all components; the roller system (upper roller and lower roller), the rotating shaft system that mounts the forming rollers; the rollers and positioning components, including forming rollers, spacers, lock nuts, key connections, etc.; and the adjustment mechanism, used to adjust the gap, level, and axial position of the rollers, so that the roller frame remains stable in terms of strength, toughness, and stability.

[0023] It is understood that in this application, in order to improve the adjustment efficiency and accuracy of the roller frame rollers and overcome the problems in related technologies where manual adjustment by vision and scale lines results in uneven adjustment pressure leading to slight roller skew, accelerated roller wear, and reduced molding stability, a pressure detection device for detecting pressure changes is added to the upper end of the support slider. This allows the adjustment force applied during operation to be adjusted based on the detection result of the pressure detection device, thereby avoiding adverse effects on the roller frame slider and rollers due to excessive adjustment force.

[0024] To better understand the roller frame adjustment device, roller frame, and adjustment method provided in this application, the following detailed description is provided in conjunction with the accompanying drawings.

[0025] Figure 2 The diagram shown is a schematic representation of the roller frame adjustment device. Figure 2 As shown, a roller adjusting device is used for the roller frame, and the roller adjusting device is located at both ends of the upper roller shaft in the roller frame.

[0026] The roller adjusting device includes: Adjusting screw 1, screw pressure plate 2, bracket slider 3, and pressure detection device 4; The bottom of the bracket slider 3 is fixed on the upper roller shaft 5, and the top is equipped with a pressure detection device 4; the screw plate 2 is fixed on the top of the pressure detection device 4, the lower end of the adjusting screw 1 passes through the screw plate 2, is engaged with the screw plate 2, and the end is in contact with the pressure detection device 4.

[0027] When the adjusting screw 1 moves up and down under the applied adjusting pressure, it drives the screw pressure plate 2 to move up and down, causing the bracket slider 3 to move up and down, thereby displacing the upper roller shaft and changing the distance between the upper and lower roller shafts.

[0028] The pressure detection device is used to detect the applied regulating pressure value, which is used to indicate the magnitude of the regulating pressure applied during subsequent regulation processes.

[0029] Specifically, such as Figure 2 As shown, the adjustment device for the roller frame may include: an adjusting screw 1, a screw pressure plate 2, and a support slider 3. The lower end of the adjusting screw 1 is engaged with the screw pressure plate 2, and then the screw pressure plate 2 contacts the pressure detection device 4 at the top of the support slider 3, so that the pressure detection device 4 can detect the adjusting pressure applied by the adjusting screw 1 to the pressure detection device. Furthermore, the screw pressure plate 2 is fixed to the pressure detection device 4.

[0030] During the adjustment of the roller frame, if the worker uses a wrench to... Figure 2 The adjusting screw 1, as shown, applies adjusting pressure. Rotating both adjusting screws causes them to move downwards or upwards. Since the lower end of adjusting screw 1 passes through the screw pressure plate 2 and engages with it, it drives the screw pressure plate to move up and down. Furthermore, because the screw pressure plate 2 is fixedly connected to the support slider 3 via the pressure detection device 4, and the support slider 3 is fixed to the upper roller shaft, the support slider 3 moves up and down with the screw pressure plate 2, driving the upper roller shaft to move. This ultimately changes the distance between the upper and lower rollers to accommodate different heights and material thicknesses. In other words, the adjusting screw drives the slider connected to the shaft to move up and down, thereby changing the distance between the upper and lower roller shafts to match rollers of different sizes.

[0031] During this process, the pressure detection device 4 can monitor the applied adjustment pressure in real time, that is, detect the change in the adjustment pressure of the roller frame in real time, and then instruct the operator to perform subsequent adjustment operations based on the monitored pressure, such as the number of turns and direction of the adjustment screw.

[0032] It is understood that, compared with related technologies, the roller frame adjustment device provided in this application can improve the adjustment accuracy by cooperating with the adjustment screw and the pressure detection device, ensuring that the adjustment amount between the two ends of the upper roller shaft remains consistent, thereby reducing the wear of the rollers, improving the stability of the roller pressing production line, reducing manual time, and improving work efficiency.

[0033] Optionally, in some embodiments of this application, a first slot 7 is provided on the top of the bracket slider, and the pressure detection device 4 is embedded in the top of the bracket slider 3 through the first slot 7.

[0034] like Figure 2 and Figure 3 As shown, a first slot 7 can be opened on the bracket slider 3, so that the pressure detection device 4 can be connected to the inside of the bracket slider 3 through the positioning pin 71.

[0035] Furthermore, such as Figure 2 and Figure 3 As shown, the screw plate 2 can be fixed to the pressure detection device 4 by screws 9.

[0036] Optionally, in some embodiments of this application, the roller frame adjustment device has a U-shaped notch on the screw plate 2, and one end of the adjustment screw 1 can contact the pressure detection device through the U-shaped notch.

[0037] Furthermore, a second slot 21 can be provided on the bottom side of the U-shaped notch, and an annular scale 8 can be fitted on one end of the adjusting screw 1, which can be locked in the second slot.

[0038] Specifically, such as Figure 2 As shown, an annular dial 8 can be fitted onto the bottom of the adjusting screw, and a second slot 21 is opened on the bottom edge of the U-shaped notch, so that the dial 8 can be locked in the second slot 21, that is, the annular dial 8 is locked at the bottom of the screw pressure plate 2, so that after the screw pressure plate 2 is fixed on the pressure detection device 4, the adjusting screw 1 can be fixed vertically on the pressure detection device 4, and the end is in contact with the pressure detection device 4. And through the cooperation of the dial 8 and the second slot 21, when the adjusting screw moves up and down, it can drive the screw pressure plate to move, that is, drive the bracket slider 3 to move.

[0039] Optionally, such as Figure 3 As shown, in some embodiments of this application, when the screw plate 2 is fixed to the pressure detection device 4, the two sides of the U-shaped notch of the screw plate can be fixed to the top of the pressure detection device by screws 9.

[0040] Optionally, such as Figure 4 As shown, in some embodiments of this application, the roller frame adjustment device has an adjustment screw 1 with the other end passing through a through hole at the top of the roller support 10; and a screw sleeve assembly 6 is provided on the protruding end of the adjustment screw, and adjustment pressure is applied by rotating the screw sleeve assembly 6.

[0041] Optionally, such as Figure 5 and Figure 6 As shown, the pressure detection device 4 includes a housing 41, a pressure sensor 42, a processor, and an alert device 43.

[0042] The reminder device 43 includes indicator lights and / or a loudspeaker, etc., installed on the outer wall of the housing; The processor receives electrical signals from the pressure sensor and controls the reminder device to perform reminder operations based on the pressure adjustment value corresponding to the electrical signal and the set adjustment pressure threshold.

[0043] Specifically, such as Figure 5As shown, the pressure detection device is equipped with an alert device 43 (such as an indicator light or horn), a setting button 44, and a reset button 45 on its outer casing 41.

[0044] A pressure sensor 42 is embedded in the top of the pressure detection device 5.

[0045] The pressure detection device 5 can be equipped with a processor, which can be an Arduino Nano (or an ATmega328P, which is small in size and easy to integrate into the test fixture; it supports analog signal reading and meets the requirements of sensor data acquisition). That is, the chip serves as the main control module of the pressure detection device.

[0046] Correspondingly, such as Figure 5 As shown, this pressure detection device can include three functional areas: Top pressure measurement area: If a thin-film pressure sensor (such as FSR402) is used, the adjusting screw on the roller frame will act on the pressure sensor to achieve pressure detection.

[0047] Furthermore, to improve the accuracy of pressure detection and the stability of the pressure detection device, a 0.5mm thick metal pad can be placed on the thin-film pressure sensor to prevent the screw from damaging the sensor and to ensure accurate pressure transmission.

[0048] Central circuit area: Located directly below the pressure measurement area, it can be configured to occupy 60% of the entire product space to fix the Arduino Nano mounting board and power interface, thereby reading pressure sensor data.

[0049] Side alarm zone: Indicator lights or horns can be installed on the side of the housing. For example, three small holes can be made in the housing to ensure that the light can be clearly seen. When the detected pressure value exceeds the threshold set by the controller, the main controller sends a command, the indicator light lights up, and the light alarm is completed.

[0050] Alarm method: LED three-color indicator (red alarm / yellow warning / green standby, brightness ≥500cd / m2).

[0051] For example, the pressure detection range can be 50-200N, the detection accuracy can be ±3% (based on the accuracy of the selected thin-film pressure sensor); response time: ≤100ms (from the pressure reaching the threshold to alarm triggering); operating voltage: DC5V (±0.2V); operating current: ≤300mA (including alarm status).

[0052] Optionally, in some embodiments, the hardware of the pressure detection device is described below for better understanding of the pressure detection device.

[0053] Firstly, regarding the pressure sensor used, in some embodiments of this application, an FSR402 thin-film pressure sensor (with signal conversion module) can be selected, such as... Figure 7 As shown.

[0054] The pressure sensor can then convert the adjustment pressure applied to the FSR sensor diaphragm area into a change in resistance, thereby obtaining pressure information.

[0055] It's understandable that the higher the pressure, the lower the resistance. This allows it to be used in applications with pressures of 50-200N.

[0056] Furthermore, for the main control module (MCU), such as Figures 6-8 As shown, the Arduino Nano (with its small ATmega328P chip, which is easy to integrate into test fixtures; it supports analog signal reading, meeting the needs of sensor data acquisition) can be selected.

[0057] like Figures 6 to 8 As shown, the processor can be configured with four pins, which can be the positive and negative terminals of the power supply voltage, the high-level output terminal, and the analog voltage signal output terminal (0~3.3V).

[0058] Furthermore, for the power module, a 5V / 2A DC power adapter can be selected (to provide stable continuous power, avoid data deviation caused by lithium battery depletion, and adapt to fixed test scenarios).

[0059] Furthermore, for the indicator lights, you can choose a 5V red LED bead + 220Ω current-limiting resistor (red has a strong visual warning effect and is suitable for "alarm" scenarios; it has low power consumption and does not add extra power burden) red alarm light + yellow warning light + green standby light.

[0060] Furthermore, the 4-digit common anode LED display is a dynamic scanning display design. It contains 4 independent 8-segment LED units, sharing a set of segment selection pins, and is equipped with 4 independent digit selection pins (to control which digit of the LED is lit).

[0061] Finally, for housing protection, a simple housing made of ABS plastic can be used, exposing only the thin-film pressure sensor test section and indicator light window, while the circuit board and power supply are fixed inside to prevent dust or debris from affecting the sensor during testing.

[0062] Correspondingly, in the actual adjustment process, the control logic flow of the processor, namely the main control module, can realize the automated logic of real-time monitoring, threshold judgment, and alarm triggering.

[0063] Specifically, such as Figure 9 As shown, it may include the following stages: (1) Initialization phase: After the processor powers on, it automatically calibrates the sensor zero point (eliminating drift error when there is no pressure), reads the threshold set by the potentiometer / button, and stores it in memory.

[0064] (2) Pressure testing stage: The processor reads the sensor signal at a frequency of 100ms / time to acquire pressure data. The data is then converted into digital values ​​by the ADC and substituted into the calibration formula (such as "pressure value = (ADC value - zero point value) × sensitivity coefficient") to calculate the actual pressure and complete the pressure data processing.

[0065] (3) Threshold judgment and execution: If the actual pressure is less than the pressure threshold: the LED indicator turns off, and the MCU continues to cycle and detect. If the actual pressure is greater than or equal to the pressure threshold: the MCU immediately outputs a high level, triggering the LED to stay on. At the same time, a "self-locking function" can be added (the alarm needs to be manually released by pressing the reset button to avoid automatic stop after accidental triggering). (4) Visual execution judgment: Specifically, in some embodiments of this application, the control module outputs segment / digit selection signals, which can drive a 4-digit LED display to dynamically scan and display the pressure value in real time. This means that an output panel can be configured for the pressure detection device, allowing the detected pressure value to be visually displayed. In other words, the real-time pressure value detected by the pressure sensor will be displayed in real time via hardware.

[0066] For example, in some embodiments, the higher the pressure, the higher the value, and the lower the pressure, the lower the value. The pressure value is precisely synchronized with the actual applied pressure, thus fully realizing the three-in-one complete function of "pressure detection + numerical visualization + over-limit alarm".

[0067] In other words, the Arduino Nano can convert the analog voltage signal acquired by the FSR402 into the corresponding value of the actual pressure using a calibration formula. Furthermore, the converted pressure value is driven by the D5-D13 pins to drive a 4-digit common anode LED display, which is refreshed in real time. For example, it displays 000 when there is no pressure and 125 / 368 / 899 when pressure is applied. The higher the pressure, the higher the value, and the lower the pressure, the lower the value. When the pressure value exceeds the alarm threshold you set, the 3 LEDs will automatically light up to sound an alarm, and the value displayed on the LED display will remain unchanged until the pressure drops below the threshold. At this point, the LEDs will turn off, and the value will continue to change with the pressure.

[0068] It is understandable that by visualizing the pressure values, operators can be provided with real-time information on pressure changes during the adjustment process. Operators can use the visualized pressure values ​​to determine the position adjustment of the roller shafts at both ends and adjust the applied pressure in real time to improve adjustment efficiency.

[0069] The pressure detection device in this embodiment can monitor the pressure during the pressure adjustment process in real time. Then, by comparing the detected adjustment pressure value with the set pressure threshold, it can indicate the magnitude of the subsequent adjustment pressure, thereby improving the adjustment accuracy and efficiency, reducing manual time, and ultimately realizing the adjustment of the roller position. This ensures that the distance between the two ends of the upper and lower rollers remains consistent after adjustment, thereby reducing the wear of the rollers in subsequent operations and improving the stability of the roller pressing production line.

[0070] On the other hand, this application also provides a roller frame, such as Figure 4 As shown, the roller frame may include two supports, an upper roller and a lower roller disposed between the two supports, and roller adjustment devices as described in the above embodiments disposed at both ends of the upper roller shaft.

[0071] It is understood that the roller frame provided in this application embodiment, by setting the adjustment device described in the above embodiments, enables the pressure detection device to monitor the applied pressure of the adjustment screw in real time during the roller adjustment process, and thus use it as the basis for roller shaft adjustment. This allows the operator to achieve efficient and precise adjustment based on the pressure values ​​on both sides, ensuring the consistency of the distance between the two rollers after adjustment. In subsequent operations, this reduces the wear of the rollers and improves the stability of the roller pressing production line.

[0072] On the other hand, this application also provides a method for adjusting the roller frame. In some embodiments, in order to improve the adjustment accuracy and efficiency, the pressure value of the pressure detection device on both sides of the roller frame can be output to a terminal, such as a laptop or mobile terminal.

[0073] For example, the detected pressure value can be output to the processing device via wired (e.g., serial communication via hardware communication line) or wireless (e.g., by configuring a Bluetooth module or radio frequency communication module in the pressure sensor).

[0074] Furthermore, after acquiring the pressure value, the processing equipment can process it according to the set pressure threshold, such as... Figure 10 As shown, the method may include the following steps: S110, acquire a first pressure value and a second pressure value. The first pressure value is acquired by a first pressure detection device located at one end of the upper roller shaft, and the second pressure value is acquired by a second pressure detection device located at the other end of the upper roller shaft.

[0075] S120, compare the magnitudes of the first pressure value and the second pressure value, as well as the set pressure threshold.

[0076] S130, Based on the comparison result, a reminder instruction is generated, which is used to instruct the reminder mechanism to perform the reminder operation.

[0077] Specifically, during the adjustment process, pressure detection devices on both sides of the roller shaft monitor the applied pressure in real time and transmit the data to the processing equipment. That is, the first pressure detection device on one side transmits the detected first pressure value to the processing equipment, and the second pressure detection device on the other side transmits the detected second pressure value to the processing equipment.

[0078] Furthermore, after receiving the first pressure value and the second pressure value, the processing device can compare them with the set pressure threshold. If neither of them exceeds the pressure threshold, the first pressure value and the second pressure value can be compared again. Finally, based on the comparison result, a corresponding reminder command is generated and sent to the corresponding pressure detection device. After receiving the reminder command, the pressure detection device responds to the reminder command and controls the reminder device to perform the reminder operation.

[0079] For example, in some embodiments, if the first pressure value exceeds the pressure threshold, a first reminder instruction is generated. This first reminder instruction is used to instruct the reminder device of the first pressure detection device to perform a reminder operation, such as causing the indicator light of the first pressure detection device to flash, alarming the staff, or stopping the operation of the adjusting screw on that side.

[0080] If the second pressure value exceeds the pressure threshold, a second reminder instruction is generated. This second reminder instruction is used to instruct the reminder device of the second pressure detection device to perform a reminder operation, such as causing the indicator light of the second pressure detection device to flash, alarming the staff, and stopping the operation of the adjusting screw on that side.

[0081] Furthermore, if the first pressure value and the second pressure value do not exceed the pressure threshold, and the difference between the first pressure value and the second pressure value exceeds the pressure difference threshold, a third reminder command is generated. This third reminder command is used to instruct the reminder device of the first pressure detection device or the second pressure detection device to perform a reminder operation. For example, when the second pressure value is greater than the first pressure value, a reminder command can be sent to the first pressure detection device to control the action of the reminder device of the first pressure detection device (e.g., through a voice reminder) to remind the operator to increase the movement of the adjusting screw on that side.

[0082] It is understood that in this embodiment, by receiving the detection values ​​from two pressure detection devices through the processing equipment and then comparing them, the operator's adjustment operation can be guided more flexibly, thereby improving the adjustment efficiency of the roller frame.

[0083] On the other hand, this application also provides an adjustment device for a roller frame, the device comprising: The acquisition module is used to acquire a first pressure value and a second pressure value. The first pressure value is acquired by a first pressure detection device set at one end of the upper roller shaft, and the second pressure value is acquired by a second pressure detection device set at the other end of the upper roller shaft. The comparison module is used to compare the magnitudes of the first pressure value and the second pressure value, as well as the magnitude of the set pressure threshold. The generation module is used to generate a reminder instruction based on the comparison result. The reminder instruction is used to instruct the reminder mechanism to perform the reminder operation.

[0084] Optionally, in some embodiments of this application, the adjusting device of the roller frame, its generating module is specifically used for: If the first pressure value exceeds the pressure threshold, a first reminder instruction is generated, which instructs the reminder device of the first pressure detection device to perform a reminder operation. If the second pressure value exceeds the pressure threshold, a second reminder instruction is generated, which instructs the reminder device of the second pressure detection device to perform a reminder operation. If the first pressure value and the second pressure value do not exceed the pressure threshold, and the difference between the first pressure value and the second pressure value exceeds the pressure difference threshold, a third reminder instruction is generated. The third reminder instruction is used to instruct the reminder device of the first pressure detection device or the second pressure detection device to perform a reminder operation.

[0085] It is understood that this application provides an adjustment device, roller frame, and adjustment method for a roller frame. By installing roller adjustment devices at both ends of the upper roller of the roller frame, the pressure during the pressure adjustment process is monitored in real time, improving the adjustment accuracy and efficiency. Specifically, in the roller adjustment device, the bottom of the support slider is fixed on the upper roller, and a pressure detection device is provided at the top. The lower end of the adjustment screw passes through the screw pressure plate fixed at the top of the pressure detection device and contacts the pressure sensor. Thus, when the adjustment screw moves up and down under the applied adjustment pressure, it can drive the screw pressure plate to move up and down, thereby driving the support slider to move up and down, ultimately causing the upper roller to shift and changing the distance between it and the lower roller. During the adjustment process, the pressure detection device can monitor the applied adjustment pressure value in real time to indicate the magnitude of the subsequent adjustment pressure, improving the adjustment accuracy and efficiency, reducing manual time, and ultimately achieving roller position adjustment. This ensures that the distance between the two ends of the upper and lower rollers remains consistent after adjustment, thereby reducing the wear of the rollers in subsequent operations and improving the stability of the roller pressing production line.
