[0002] Welded pipe machining is a process of making steel pipes from strip steel through a series of forming and welding processes. In this process, the strip steel conveying mechanism plays a crucial role. This mechanism is responsible for gradually unwinding the strip steel from the coil and stably conveying it to various processing equipment. Traditional strip steel conveying mechanisms mainly include tensioning devices, guide wheels, and conveying rollers, ensuring that the strip steel moves smoothly and efficiently throughout the production line. With the improvement of industrial automation level, modern welded pipe production lines have increasingly strict requirements for strip steel conveying mechanisms, not only requiring high-precision conveying capacity but also intelligent detection and automatic adjustment functions to cope with complex production environments.

[0025] In the embodiment two, the driving roller 2 and the driven roller 3 are arranged in linear array on the inner side of the driving frame 1, and the driving roller 2 and the driven roller 3 are arranged in several groups. The several groups of driving roller 2 and driven roller 3 can improve the stability of the strip during the conveying process. The bottom of the support frame 5 is fixedly connected with the support block 4. The support frame 5 stably supports the support block 4. The motor 12 is arranged on one side of the controller 9. The motor 12 is fixedly installed on the upper surface of the support frame 5. The motor 12 is electrically connected with the controller 9. The controller 9 can control the forward and reverse rotation of the motor 12. The output end of the motor 12 penetrates through the support frame 5 and is fixedly connected with one end of the connecting shaft 13. The support frame 5 limits the connecting shaft 13. The other end of the connecting shaft 13 is fixedly sleeved with the gear 14. The gears 14 on both sides are engaged with one end of the rack 15. The other end of the rack 15 is fixedly connected with the moving frame 6. The moving frame 6 is slidably connected with the support frame 5 through the slide rail 16. The slide rail 16 is fixedly installed on the support frame 5. The support frame 5 is provided with the limiting plate 17 on both sides.

[0026] When the strip is deflected, the contact sensor 11 is in contact with the contact 10, and a signal is triggered to the controller 9.

The limiting shell 7 drives the strip to gradually return to the correct position through the connection with the correction block 8 until the contact sensors 11 on both sides are in contact with the contact 10, which indicates that the strip has been completely aligned and is no longer deflected. At this time, the controller 9 instructs the motor 12 to rotate reversely, and drives the correction block 8 to return to the initial position, completing a complete correction cycle.

In combination with this mechanism, the design of the deviation correction block 8 further enhances the stability and reliability of the system. Specifically, the deviation correction block 8 is fixedly connected with an anti-skid soft pad 18 on one side, which helps to increase the friction between the strip and the deviation correction block 8, preventing the strip from slipping during adjustment, thereby ensuring that the correction effect is more accurate and stable. The other side of the deviation correction block 8 is fixedly connected with the contact 10, and the contact 10 is used to trigger the contact sensor 11. When the strip deviates, the contact 10 contacts the contact sensor 11, sending a signal to the controller 9 to start the correction process.

The buffer spring 19 provides buffering and resetting functions during the correction process. When the strip deviates, the buffer spring 19 can absorb the impact force to avoid excessive mechanical stress on the contact 10 and the contact sensor 11, prolonging the service life of the equipment. At the same time, the buffer spring 19 can also help the deviation correction block 8 to reset smoothly after the strip returns to the correct position, ensuring that the entire system is always in the best working condition. This design not only improves the reliability of production, but also ensures the stability of product quality, effectively preventing production accidents and quality problems caused by deviation.
