Description

Technical Field

[0001] The invention belongs to the technical field of hot rolling production equipment, and in particular relates to an automatic hot rolling steel strip packaging workbench. Background Art

[0002] The production of hot-rolled steel strip is an important link in the metallurgical industry. The traction and transmission in the production process have an important impact on product quality and production efficiency. With the continuous development of steel manufacturing technology, the automated production of hot-rolled steel strip has become a key technical direction for improving production efficiency and reducing costs. In traditional hot rolling production lines, the traction and transmission of steel strips usually rely on manual operation, especially in the traction and straightening of the head of the steel strip, workers need to manually use tools such as pliers to operate. This not only greatly increases the labor intensity of workers, but also brings serious safety hazards. Since the temperature of hot-rolled steel strips is usually between 500 and 600°C, direct contact will lead to frequent scalding accidents, especially in high temperature environments, workers are also prone to safety accidents such as heat stroke.

[0003] In the existing steel belt traction and transmission equipment, the degree of mechanization and automation has been improved, but the design of most systems still has the following problems: First, the coordination between the various transmission and traction equipment is not smooth enough, which can easily cause the steel belt to bend or deflect during the transmission process, resulting in unstable operation of the subsequent coiler. Secondly, the existing equipment usually relies on single-speed transmission control and cannot dynamically adjust the traction speed according to the actual working conditions, resulting in the mismatch of the speed of the steel belt in different sections during the production process, affecting the overall production efficiency. In addition, most of the existing equipment lacks the function of automatic correction of the posture of the steel belt, especially when the steel belt is in a free state after the serpentine oscillator guide groove, the steel belt is prone to bending, and manual intervention is required to adjust the position of the steel belt head. This not only increases the dependence on manual labor, but also affects the continuity and efficiency of production.

[0004] With the continuous development of intelligent manufacturing technology, the automation and intelligentization trend of the steel industry is becoming increasingly obvious. Various solutions based on robotics, intelligent control algorithms and automation systems are gradually being applied to steel belt traction and transmission systems. The core goal of these solutions is to reduce manual participation, improve system stability and production efficiency, and realize automatic adjustment of equipment operation through optimized control algorithms. However, most automation systems on the market still rely on fixed control logic and lack the ability to dynamically adjust real-time data in the production process, especially in the posture correction and speed optimization control of steel belts. There are still many deficiencies. Summary of the invention

[0029] Beneficial effects of the present invention:

[0030] In view of the shortcomings of the prior art, the present invention provides a steel strip traction device and a conveying device for a hot rolling production line based on an optimization control algorithm, aiming to solve the problems of low manual operation efficiency, great safety hazards, and poor production continuity. The present invention realizes the dynamic adjustment of the steel strip traction speed and the automatic correction of the steel strip posture by introducing a real-time data feedback system, an optimization control algorithm, and an adaptive control technology, thereby reducing manual intervention while improving production efficiency, and significantly improving the automation level and safety of the production line. The device can not only operate stably in a high-temperature and high-speed working environment, but also automatically optimize the control parameters according to the position and speed deviation of the steel strip, ensuring the continuity and consistency of the posture and speed of the steel strip during the transmission process, and realizing the full process automation operation from the steel strip out of the groove to the coiling.

[0031] The present invention realizes dynamic adjustment of the steel belt traction speed through an optimized control algorithm, effectively solving the problem that traditional equipment cannot automatically adjust the speed according to actual working conditions. In the production process, different sections of the steel belt usually require different transmission speeds, and most of the existing technologies use fixed speed control, resulting in poor matching. The speed optimization formula adopted by the present invention can adaptively adjust the traction speed by real-time monitoring of the position information and speed deviation of the steel belt, thereby improving the overall efficiency of the production line and avoiding the accumulation or stagnation of the steel belt caused by speed mismatch.

[0032] The gripping device of the present invention combines the lateral and vertical drive mechanisms to achieve automatic straightening and posture correction of the steel belt, reducing the need for manual intervention. Compared with the prior art method of relying on manual use of tools to straighten the steel belt, the gripping device of the present invention can automatically correct when the steel belt deviates from the target position and maintain precise control as the steel belt moves. This multi-dimensional automatic adjustment capability greatly improves the continuity and safety of production, and avoids subsequent process errors caused by unstable steel belt posture in traditional methods.

[0033] The present invention realizes the monitoring and dynamic adjustment of real-time data in the production process by introducing a closed-loop feedback control system. Existing systems often use open control logic, which makes it difficult to adjust production parameters in real time. The present invention collects the motion data of the steel strip in real time to form a closed-loop feedback mechanism to ensure the accuracy and response speed of the traction speed and position correction. This feedback control system greatly reduces the error rate in the production process, makes the posture and position of the steel strip during transmission more accurate, and improves the intelligence level and stability of the overall production line.

[0034] The application of the adaptive control algorithm enables the present invention to automatically optimize the control parameters according to the production environment and load conditions. Compared with the fixed parameter control in the prior art, the adaptive algorithm of the present invention ensures the efficient operation of the system under different working conditions by calculating the error in real time and adjusting the traction parameters. This dynamic optimization method not only improves production efficiency, but also reduces equipment wear and energy consumption caused by changes in the production environment, making the system run more smoothly and efficiently.

[0080] The above is a detailed description of the steel strip conveyor device of the hot rolling production line. The present invention also provides an automatic hot rolling steel strip packaging workbench based on the steel strip conveyor device of the hot rolling production line. The control logic of the packaging workbench is as follows:

[0081] System initialization phase

[0082] Equipment calibration: When the system starts, calibrate the positions of all driving devices (lateral driving structure, vertical driving mechanism) and gripping devices to ensure that the equipment is in the initial state.

[0083] Steel belt position detection: The distance detection element on the sliding car is used to detect the steel belt position in real time and transmit it to the central controller.

[0084] Optimization goals: maximize traction speed, ensure continuity, and reduce downtime.

[0085] 2. Steel belt grabbing stage

[0086] Steel belt positioning: When the steel belt passes through the serpentine oscillator guide groove and reaches the free state, the system detects the position and angle of the steel belt in real time. If the steel belt deviates too much, the automatic straightening function is activated.

[0087] Grasping device presses down: According to the position of the steel strip, the horizontal drive and vertical drive mechanism are used to accurately align the grabbing device with the head of the steel strip. The vertical drive mechanism presses down the grabbing device to complete the grabbing.

[0088] 3. Transmission and traction stage

[0089] Automatic movement: The sliding car is adjusted according to the position of the steel belt. After the grabbing device grabs the steel belt, the sliding car starts to move along the sliding track.

[0090] Optimized traction speed formula: traction speed v opt The optimization formula can be expressed as:

[0091]

[0092] Among them, v nom is the nominal speed, e p is the deviation between the current grasping position and the target position, e v is the difference between the current speed and the ideal speed. k1 and k2 are optimization parameters that determine the smoothness and accuracy of the speed response.

[0093] Control feedback: The sliding car provides real-time feedback on its movement speed and distance, and adjusts the traction speed according to the optimized control algorithm formula to ensure the continuity of the steel belt.

[0094] Position and safety correction phase

[0095] Position correction: If posture deviation of the gripping device or steel belt is detected, the system adjusts the lateral or vertical movement of the gripping device according to the deviation value to achieve precise traction and transportation.

[0096] Safety protection: When the grabbing device detects abnormal temperature or position of the steel belt, the system will automatically slow down or stop pulling to prevent equipment damage or personal injury.

[0097] 5. Automation and adaptive control

[0098] Adaptive optimization: Based on real-time data, the system continuously adjusts the motion parameters of the traction device through machine learning algorithms to keep the equipment in the optimal state under different workloads and speeds. The following adaptive control formula can be used:

[0099]

[0100] in:

[0101] e(t) is the real-time error of the system, K p , K i , K d is the gain coefficient of adaptive control.

[0102] Termination Phase

[0103] Automatic return: When the traction is completed or the steel belt is fully curled, the grabbing device automatically returns to the initial position and prepares for the next task.

[0104] System feedback and update: All detected data is transmitted to the central control system, which analyzes the current operating status and optimizes the control logic in subsequent production cycles based on empirical data.

[0105] In practical application:

[0106] This implementation method includes the following key steps:

[0107] Equipment initialization and data collection

[0108] Before starting the production line, the equipment is first initialized, and all drive devices (such as horizontal drive mechanism, vertical drive mechanism, etc.) are reset to the initial position. At the same time, the distance detection element on the sliding car begins to collect the position and posture data of the steel strip in real time to ensure that the data is accurately input into the control system.

[0109] By collecting data such as the steel belt's motion trajectory and speed in real time, the system can form a closed-loop feedback loop to ensure more precise traction and correction in subsequent steps.

[0110] Grasping and posture correction

[0111] After the steel belt passes through the guide groove of the serpentine oscillator, it is in a free state and is prone to bending or deviation. The system automatically determines the position deviation of the steel belt through the real-time position information collected.

[0112] The horizontal drive and vertical drive mechanisms adjust the position of the grabbing device by optimizing the control logic, so that the grabbing device is accurately aligned with the head of the steel strip. The grabbing device automatically corrects the posture of the steel strip by coordinating the longitudinal and lateral adjustments, reducing human intervention.

[0113] Optimization of traction speed

[0114] After the steel strip is grabbed, the sliding car starts to drive the grabbing device to move along the sliding track and pull the steel strip to the winding mechanism. During the pulling process, the pulling speed is adjusted by optimizing the speed control algorithm. The system monitors the position and speed deviation of the steel strip in real time.

[0115] Feedback Control and Adaptive Optimization

[0116] During the traction process, the system detects the status of the steel belt in real time through the feedback control module. If the position deviation of the steel belt exceeds the set threshold, the system will automatically adjust the position and traction speed of the grabbing device according to the feedback information to ensure the stability of the steel belt during the transmission process.

[0117] The adaptive control algorithm continuously optimizes control parameters based on real-time data from the production process to adapt to different working conditions and ensure that the traction device can still operate smoothly under high load and high speed conditions.

[0118] Termination and Reset

[0119] When the steel strip is pulled to the coiling position, the grabbing device automatically returns to the initial position to prepare for the next round of operation. At the same time, the control system records the entire operation process to facilitate the next round of production optimization and adjustment.

[0120] Specific:

[0121] Example 1: Operations during conventional steel strip production

[0122] In conventional hot-rolled steel strip production, the temperature of the steel strip is about 500-600°C, and the production line requires continuous and efficient operation. In this embodiment, after the system is initialized, the head of the steel strip is first grabbed and the posture is corrected. After the automatic adjustment of the grabbing device is completed, the sliding car begins to move along the sliding track and adjusts the traction speed according to real-time feedback. During the traction process, the system dynamically adjusts the traction speed and the position of the grabbing device through an adaptive control algorithm to ensure that the steel strip enters the coiler smoothly. The entire process is highly automated, without the need for manual intervention, and the production speed is about 15% higher than the traditional method.

[0123] Example 2: Production under high temperature and high load conditions

[0124] In a high-temperature and high-load production environment, the temperature of the steel strip may be higher than 600°C, and the operation of the production line needs to be more stable. In this embodiment, the system achieves more precise control of the posture and speed of the steel strip by strengthening real-time data acquisition and feedback control. The grabbing device quickly grabs and straightens the head of the steel strip through the cooperation of the lateral and vertical drive mechanisms. During the traction process, the adaptive control algorithm automatically adjusts the traction speed according to the production load to avoid speed fluctuations caused by excessive temperature or excessive load. Compared with traditional methods, the traction efficiency of this embodiment at high temperature is improved by about 20%, and energy consumption is reduced.

[0125] Example 3: Automatic traction and correction of multiple steel strips

[0126] In some special production tasks, the steel strips may have different lengths or thicknesses, requiring speed adjustments in different sections. In this embodiment, the system can automatically optimize the traction speed according to the length and thickness differences of the steel strips. In specific operations, the grabbing device first performs multiple posture corrections to ensure that steel strips in different sections can be accurately grabbed. Subsequently, the system dynamically adjusts the traction speed based on the actual data of each section to ensure speed matching of different sections during the transmission process. Compared with the traditional fixed speed control method, the traction continuity of this embodiment is better, which is particularly suitable for the automated production of heterogeneous steel strips, reduces human intervention, and significantly improves production efficiency.

[0127] The steel strip conveying device for a hot rolling production line described in this embodiment does not require manual operation close to the production line, thus reducing the waste of human resources, while also ensuring the personal safety of workers and avoiding the occurrence of construction safety accidents; and the device is arranged on the hot rolling steel strip production line, and can realize clamping and straightening operations at any position on the production line where the steel strip needs to be straightened and pulled, thereby achieving the effect of controlling the posture of the steel strip on the production line, and is suitable for existing hot rolling forming steel strip production lines.
