[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is equipped with a top limit module, a side limit module and a shearing module, and a multiple limit system of the top limit module and the side limit module is designed to ensure the stability and position accuracy of the plate during the leveling and shearing process. The top limit module is driven by an electric telescopic rod, and can automatically adjust the height of the pressing plate according to the thickness and material of the plate, so that the plate is tightly fitted from above during the shearing process, effectively preventing the plate from being offset or deformed due to uneven force. The side limit module achieves precise fixation of the side of the plate through the cooperation of the limit plate and the micro electric push rod. The design of the limit groove can closely fit the edge of the plate, ensuring that the plate maintains a stable posture during the shearing process, and the micro electric push rod can push the sheared plate to the discharge port after the shearing is completed. The top limit module and the side limit module work together The effect reduces the deviation and shaking of the plate during the shearing process, thereby improving the overall feeding accuracy. The production line is clearly divided into a leveling room and a shearing room. The two areas are equipped with corresponding functional components, so that the plate can go through the two processes of leveling and shearing in turn, realizing the efficient and continuous processing flow. At the same time, through the use of servo motors, electric telescopic rods and micro electric push rod automation equipment, manual intervention is reduced and the degree of automation of the production line is improved, which can not only improve production efficiency but also reduce the labor intensity of operators. The precise limit and stable conveying system jointly ensure the stability and accuracy of the plate during the processing, thereby ensuring the processing quality of the final product. Therefore, the problems of low feeding accuracy, low processing efficiency, insufficient flexibility and unstable processing quality in the plate processing process can be solved.

[0016] 2. The present invention installs a limit plate, a mounting groove, a limit groove and a micro electric push rod. When the shear knife completes a plate shearing, the electric telescopic rod 2 drives the shear knife to move upward and retract the shear knife. At this time, the electric telescopic rod 1 drives the pressure plate to move upward, and the servo motor 1 drives the discharging conveying roller to rotate in the opposite direction and then stops. The micro electric push rod extends to push out the plate inside the mounting groove and the limit groove, and the sheared plate is discharged from the discharging port. The micro electric push rod shortens, and then the servo motor 1 drives the discharging conveying roller to rotate forward until one end of the plate is fixed inside the limit groove, and the plate is sheared and pushed out repeatedly. The design of the limit plate and the limit groove can accurately fix the position of the plate during the shearing process, prevent the plate from being offset or moved during shearing, thereby ensuring the shearing accuracy and plate quality. The application of the micro electric push rod realizes the automatic pushing out of the plate. After the shearing is completed, the micro electric push rod extends to push out the plate inside the mounting groove and the limit groove, so that the sheared plate is smoothly discharged from the discharging port without manual intervention, thereby improving production efficiency and automation. Through the coordinated work of the electric telescopic rod 1, the electric telescopic rod 2, the servo motor 1 and the micro electric push rod, continuous and efficient production of the plate is realized, forming a complete production cycle, greatly improving production efficiency, and automated plate pushing and continuous production reduce manual intervention, reduce the labor intensity and safety risks of operators, and at the same time, precise plate positioning and fixation also reduce the possibility of equipment damage and personal injury caused by plate offset or movement. Therefore, the problems of inaccurate plate positioning, non-automatic pushing, low production efficiency, poor adaptability and frequent manual intervention can be solved.

[0017] 3. The present invention is equipped with a laser displacement sensor, an acoustic sensor, a strain gauge pressure sensor 1 and a strain gauge pressure sensor 2. The laser displacement sensor detects the position of the plate at the exit and entrance of the leveling chamber and the shearing chamber, and can monitor the movement and positioning of the plate in real time and accurately, ensuring that the plate is always in the correct position during the leveling and shearing process, thereby improving the feeding accuracy of the production line. The acoustic sensor monitors the sound generated during the leveling and shearing process, which can help identify the equipment operation status and potential faults, including bearing wear and tool damage, so as to perform maintenance and adjustments in time to ensure the stability and efficiency of the processing process. The strain gauge pressure sensor 1 monitors the pressure on the shearing knife during the shearing process, which can be realized. Real-time feedback of the shear force helps to optimize the shearing parameters, including shearing speed and tool angle, to improve shearing quality and tool life. The strain gauge pressure sensor measures the pressure of the leveling roller on the plate during the leveling process, which can ensure that the leveling pressure is moderate, achieving the leveling effect while avoiding excessive pressure on the plate, improving the leveling quality and plate utilization. Through the comprehensive application of multiple sensors, a more comprehensive monitoring system can be established to monitor and analyze the operating status of the production line in real time, promptly discover and deal with potential faults, reduce downtime and maintenance costs, and therefore solve the problems of position control in the plate processing process, monitoring and optimization of the processing process, fault diagnosis and prevention, and improvement of the intelligent level of the production line.

[0018] 4. The present invention is equipped with ultrasonic thickness sensor 1, ultrasonic thickness sensor 2 and speed sensor. Ultrasonic thickness sensor 1 can accurately measure the original thickness of the unleveled plate, which provides important reference data for the subsequent leveling process. By understanding the initial thickness of the plate, the gap and pressure of the leveling roller can be adjusted more accurately to ensure that the thickness of the plate after leveling is uniform and meets the requirements. Ultrasonic thickness sensor 2 is used to measure the thickness of the plate after leveling to verify the leveling effect. By comparing the thickness of the plate before and after leveling, it can be evaluated whether the adjustment of the leveling roller is accurate and whether further adjustment is needed to achieve the best leveling effect. The speed sensor is installed on the motor shafts of servo motor 1, servo motor 2 and servo motor 3, and can measure the conveying speed and leveling speed of the plate on the feed conveyor roller, the discharge conveyor roller and the leveling roller in real time. It is very important to ensure the stability and continuity of the plate in the entire processing process. By monitoring The data provided by the speed control sensor can timely discover and solve the problem of inconsistent or excessive fluctuation in conveying speed, thereby avoiding quality problems such as misalignment, scratches or deformation of the plate during processing. Combined with the data of the ultrasonic thickness sensor and the speed sensor, the processing parameters can be adjusted and optimized more accurately, including the gap, pressure, and rotation speed of the leveling roller and the rotation speed of the conveying roller, etc., which can not only improve the leveling quality and processing efficiency of the plate, but also extend the service life of the equipment and reduce maintenance costs. By introducing a variety of sensors and real-time monitoring technologies, the plate leveling and shearing production line of the present invention has a higher level of intelligence. The sensor data can be used as an input for the intelligent control system to realize automation and intelligent control, and automatically adjust the processing parameters according to the thickness of the plate and the conveying speed, thereby improving the adaptability and flexibility of the production line. Therefore, the problems of inaccurate thickness measurement, unstable conveying speed and inaccurate adjustment of processing parameters in the plate processing process can be solved.

The feed conveyor roller 20 is made of high-quality alloy steel. The surface of the feed conveyor roller 20 is specially treated to improve wear resistance and corrosion resistance. The surface of the feed conveyor roller 20 is provided with an anti-slip texture and an anti-slip coating to increase the friction between the plate and prevent the plate from sliding or deflecting during transportation.

[0050] During the feeding process of the plate leveling and shearing production line, servo motor three starts and drives the feed conveyor roller 20 to rotate. The plate is placed on the feed conveyor roller 20. As the roller rotates, the plate is smoothly and continuously conveyed to the leveling area. The control system can monitor the position and speed of the plate in real time, and adjust the speed and direction of servo motor three as needed to ensure that the plate always maintains a constant speed and position during the feeding process.

[0051] See also Figure 2 The present invention provides an embodiment: a plate leveling and shearing production line with high feeding accuracy, wherein the bottom wall of the leveling chamber 2 is embedded with an ultrasonic thickness sensor 1 and an ultrasonic thickness sensor 2, and the ultrasonic thickness sensor 1 is located between the feed conveying roller 20 and the leveling roller 18, and the ultrasonic thickness sensor 2 is located between the leveling roller 18 and the discharge conveying roller 5, the ultrasonic thickness sensor 1 is used to measure the original thickness of the plate before leveling, and the ultrasonic thickness sensor 2 is used to measure the thickness of the plate after leveling.

[0052] Furthermore, an ultrasonic thickness sensor 1 is embedded in the bottom wall of the leveling chamber 2 and is located between the feed conveying roller 20 and the leveling roller 18. The function of the ultrasonic thickness sensor 1 is to measure the original thickness of the plate before leveling. By emitting ultrasonic waves to the plate and receiving the reflected signal, the sensor can accurately calculate the thickness value of the plate.

[0053] Ultrasonic thickness sensor 1 uses the propagation speed and reflection characteristics of ultrasonic waves in solid media for measurement. When ultrasonic thickness sensor 1 transmits ultrasonic waves to the plate, the ultrasonic waves will propagate inside the plate and reflect back from the bottom surface. Ultrasonic thickness sensor 1 measures the round-trip time of the ultrasonic waves and calculates the thickness of the plate based on the known propagation speed of the ultrasonic waves in the plate.

[0054] The measured original thickness data of the plate will be transmitted to the control system in real time. The control system can adjust the gap and pressure of the leveling roller 18 and other parameters according to these data to ensure that the plate is properly treated during the leveling process.

[0055] Ultrasonic thickness sensor 2 is embedded in the bottom wall of the leveling chamber 2, but is located between the leveling roller 18 and the discharge conveyor roller 5. The function of ultrasonic thickness sensor 2 is to measure the thickness of the plate after leveling to verify whether the leveling effect reaches the expected effect. Like ultrasonic thickness sensor 1, ultrasonic thickness sensor 2 also uses the propagation speed and reflection characteristics of ultrasonic waves for measurement. By emitting ultrasonic waves to the plate after leveling and receiving the reflected signal, ultrasonic thickness sensor 2 can accurately calculate the thickness value of the plate.

[0056] The measured thickness data of the plate after leveling will also be transmitted to the control system in real time. The control system can make feedback adjustments to the leveling process based on these data to further optimize the leveling effect. At the same time, these data can also be used for quality control and statistical analysis to help production personnel understand the quality stability and consistency of plate leveling.

[0057] See also Figure 2The present invention provides an embodiment: a plate leveling and shearing production line with high feeding accuracy, wherein speed sensors are installed on the motor shafts of the servo motor 1, servo motor 2 and servo motor 3, and the speed sensors are used to measure the conveying speed and leveling speed of the plate on the feed conveyor roller 20, the discharge conveyor roller 5 and the leveling roller 18.

[0058] Further, the use of the plate leveling and shearing production line is as follows: S1, the plate enters the leveling chamber 2 through the feed port 21 for leveling; S2, the flattened plate is transported to the shearing chamber 3 through the discharging conveying roller 5 for shearing; S3, the sheared sheet is output through the discharge port 22.

[0059] Furthermore, in S2, the following steps are also included: S21, one end of the plate moves to the limit groove 11 and stops moving, the electric telescopic rod 1 6 of the top limit module pushes the pressing plate 7 down to fix the plate, and the electric telescopic rod 2 8 drives the shearing knife 9 to shear the plate; S22, a strain gauge pressure sensor monitors the pressure of the shearing knife 9, an acoustic sensor monitors the shearing sound, and a laser displacement sensor detects the position of the plate before shearing.

[0060] Working principle: The plate enters the leveling chamber 2 through the feed port 21, the laser displacement sensor detects the position of the plate to ensure the stability of the plate during the leveling process, the servo motor 2 drives the leveling roller 18 to rotate to level the plate, the ultrasonic thickness sensor 1 measures the original thickness of the plate, the ultrasonic thickness sensor 2 measures the thickness of the plate after leveling, and the strain gauge pressure sensor 2 monitors the pressure of the leveling roller 18 on the plate to ensure the leveling effect.

[0061] The leveled sheet is conveyed to the shearing chamber 3 by the discharging conveying roller 5. One end of the sheet moves to the limit groove 11 and stops moving. The electric telescopic rod 1 6 of the top limit module pushes the pressure plate 7 to descend and fix the sheet. The electric telescopic rod 2 8 drives the shearing knife 9 to descend and shear the sheet. The strain gauge pressure sensor 1 monitors the pressure of the shearing knife 9, the acoustic sensor monitors the shearing sound, and the laser displacement sensor detects the position of the sheet before shearing. When the shearing knife 9 completes a sheet shearing, the electric telescopic rod 2 8 drives the shearing knife 9 to move upward and retract the shearing knife 9. At this time, the electric telescopic rod 1 6 drives the pressure plate 7 to move upward, and the servo motor 1 drives the discharging conveying roller 5 to rotate in the opposite direction and then stops. The micro electric push rod 12 extends to push out the sheet inside the installation groove and the limit groove 11, and the sheared sheet is discharged from the discharging port 22. The micro electric push rod 12 shortens, and then the motor 1 drives the discharging conveying roller 5 to rotate forward until one end of the stopped sheet is fixed inside the limit groove 11, and the sheet is sheared and pushed out repeatedly, and the sheared sheet is output through the discharging port 22.
