[0022] The following detailed description of the embodiments is used to exemplify the principles of the present invention, but should not be used to limit the scope of the present invention. The present invention can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
[0023] These embodiments are provided to make this disclosure thorough and complete, and to fully express the scope of the invention to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, material composition, numerical expressions, and values set forth in these embodiments should be interpreted as merely exemplary and not as limiting.
[0024] It should be noted that, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicating orientation or positional relationships, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0025] It should also be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. When a specific device is described as being located between a first device and a second device, an intermediary device may or may not be present between the specific device and the first or second device.
[0026] All terms used in this invention have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.
[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.
[0028] like Figure 1 As shown, this utility model provides a strip steel continuous operation unit correction device, which includes an insulating plate; a conductive element, which is mounted on the insulating plate and set at the strip steel limit detection position; and a controller, which includes a power supply module and is electrically connected to the conductive element.
[0029] When strip 2 reaches the limit detection position, it comes into contact with the conductive element and forms a circuit with the power supply module of the controller.
[0030] The limit detection position of strip steel can correspond to the critical position indicating that the strip steel has deviated, or the limit position that the strip steel is allowed to reach without deviating.
[0031] In the strip steel continuous running unit correction device according to the embodiment of this utility model, the correction limit detection is modified, and no additional sensor is required. Correction is achieved by switching the circuit between the conductive element and the strip steel 2. It is simple to manufacture, easy to install, increases stability, reduces failure rate, can effectively improve production efficiency, reduce equipment wear, and is not easily affected by the site environment. It has significant improvement effects in terms of safety, operability, maintenance capability and adaptability, and has good application value. It is suitable for market promotion and use.
[0032] In some specific embodiments, the number of conductive elements is two, with the two conductive elements respectively disposed on both sides of the strip width direction. Setting the number of conductive elements to multiple can cover a wider range, thereby expanding the detection range of strip deviation.
[0033] Based on the above embodiments, the distance between the two conductive elements is greater than the width of the correction frame 4. In actual production, due to various reasons (such as equipment vibration, uneven tension, uneven material, etc.), the deviation of the strip 2 may fluctuate significantly. A larger spacing between conductive elements can better adapt to this situation, improve the fault tolerance of the system, and reduce detection failures caused by extreme deviation conditions.
[0034] Based on the above embodiments, the conductive element is a galvanized steel strip 1. The galvanized steel strip 1 has good conductivity, ensuring efficient transmission of the detection signal. In the web correction device, the conductive element needs to transmit the strip edge position information to the controller in real time. The low resistance of the galvanized steel strip 1 can reduce energy loss during signal transmission, improve signal stability and response speed, thereby enhancing the accuracy and real-time performance of the web correction control.
[0035] Preferably, the galvanized steel strips 1 are symmetrically arranged with the unit centerline as the reference. On a production line with a wider strip 2, a single galvanized steel strip 1 may not be able to cover the entire width of the strip 2, while two symmetrically arranged galvanized steel strips 1 can better monitor the deviation of the strip 2 in both left and right directions, improve the detection capability of the overall deviation of the strip 2, and ensure that abnormalities can be detected in a timely manner in different deviation directions.
[0036] When strip 2 deviates and comes into contact with galvanized steel strip 1, the symmetrical arrangement ensures a certain degree of symmetry in the force distribution. If there is only one galvanized steel strip 1, the deviated strip 2 will generate lateral force upon contact, which may cause uneven stress on the insulation board, installation structure, etc., and long-term use may lead to structural deformation or damage.
[0037] In some specific embodiments, the conductive element is positioned behind the straightening roller 3 and the straightening frame 4 along the strip's running direction. Located behind the strip's running path, the conductive element can directly detect the actual position of the strip's edge. Due to its proximity to the strip exit, it can capture the strip's lateral deviation during operation in real time, providing timely and accurate feedback signals to the controller.
[0038] In some specific embodiments, the power supply module is a 24V DC power supply module. 24V DC voltage is relatively low, falling within the safe voltage range, and poses little risk of electric shock to the human body. During equipment maintenance and operation, even if an operator accidentally comes into contact with a 24V DC line, the risk of electric shock is low, ensuring personnel safety.
[0039] Based on the above embodiments, the negative terminal of the power supply module is grounded, and the positive terminal is electrically connected to the conductive element.
[0040] When the power supply module is a 24V DC power supply module, the 24V- terminal of the 24V DC power supply module is grounded, and the 24V+ terminal is electrically connected to the galvanized steel strip 1. Grounding the negative terminal (24V-) of the 24V DC power supply provides a safe protection path.
[0041] In some specific embodiments, the correction device also includes an alarm module, which is communicatively connected to the controller. When the correction device detects that the strip 2 is off-track, the controller will quickly send relevant information to the alarm module, which can immediately issue an alarm so that appropriate measures can be taken in a timely manner to avoid more serious consequences caused by failure to detect the deviation in time, such as strip 2 getting stuck and scrapped, or equipment damage.
[0042] Based on the above embodiments, the alarm module issues an alarm signal when it determines that strip 2 has shifted to the limit detection position and formed a loop with galvanized steel strip 1. The alarm signal allows operators to intervene while the shift of strip 2 is still under control, avoiding safety hazards caused by further shift of strip 2.
[0043] Timely alarm signals help reduce product quality issues caused by strip misalignment. Strip misalignment can cause deviations in product dimensions, shape, or surface quality, affecting product consistency and precision. Through alarms and subsequent corrective actions, product quality fluctuations can be controlled within a small range, ensuring that products meet quality standards.
[0044] In some specific embodiments, the alarm module includes a light alarm and / or a sound alarm and / or a display screen.
[0045] Light signals are highly intuitive, conveying different information through varying colors, brightness, and flashing frequencies. For example, red lights typically indicate an emergency stop or hazard warning, yellow lights indicate caution or slow down, and green lights indicate normal operation or a safe state. This intuitive visual representation allows operators to quickly identify and understand alarm messages.
[0046] Sound signals have the characteristic of propagating in all directions with equal energy, and the human ear can receive sounds from all directions without turning the head or body. This makes the transmission of sound signals unrestricted by the location of the signal source.
[0047] Based on the above embodiments, the controller is a PLC remote cabinet. Using a PLC remote cabinet as the controller enables remote operation of the strip steel production line 2. Operators can operate and monitor the PLC remote cabinet from a central control room or other remote location far from the production site via network or communication lines. For large strip steel production enterprises, this reduces the need for operators to work long hours in harsh production environments, improving work comfort and safety.
[0048] Based on the above embodiments, the correction device also includes an emergency stop button located on the controller. In case of an emergency, such as severe deviation of the strip 2, abnormal equipment vibration, threat to personnel safety, or other unexpected events, the operator can immediately press the emergency stop button on the controller. This button will trigger the equipment's emergency shutdown procedure, quickly cutting off the power to the relevant equipment or stopping the running equipment to prevent more serious accidents.
[0049] A specific application of this invention is as follows: Determine the limit detection position of strip 2 and install an insulating plate. Install galvanized steel strip 1 on the insulating plate. The PLC remote cabinet provides a 24V signal; 24V+ is connected to the galvanized steel strip 1, and 24V- is grounded. When strip 2 deviates and contacts the galvanized steel strip 1, the 24V DC power supply module is connected to the PLC to form a circuit, generating an alarm signal. The unit immediately stops, reducing the risk of strip 2 continuing to sag and become waste.
[0050] This utility model has the following advantages: 1. Stable detection signal; 2. Low cost and high feasibility; 3. Unaffected by the environment; 4. Extended service life of spare parts; 5. Reduced downtime; 6. Reduced scrap rate and increased yield.
[0051] The strip steel continuous running unit correction device provided by this utility model achieves correction by switching the circuit on and off, which can significantly enhance the detection accuracy of the steel coil's extreme deviation. In extreme cases, such as when the edge of the steel coil approaches or touches the equipment's limit position, the device can also quickly and accurately capture the deviation signal, providing a reliable basis for timely corrective measures. This helps prevent production interruptions and equipment damage caused by deviation, thereby ensuring the continuity and stability of production. Through optimized structural design and material selection, the correction device reduces wear and fatigue of spare parts during the correction process, thus extending the service life of spare parts. This not only reduces the frequency and cost of spare parts replacement but also reduces downtime caused by spare parts failure, further improving the overall efficiency of the production line. This correction device also significantly improves the automation level of the production line. Through integration with PLC and other automated control equipment, it achieves real-time monitoring and automatic correction of strip steel deviation, reducing the need for manual intervention, lowering operational difficulty and labor intensity, while improving the intelligence level and production efficiency of the production line.
[0052] Those skilled in the art should understand that, in the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
