[0011] (1) During the metal plate processing, the rollers and belts set on both sides of the device can not only apply a stable clamping force to the metal plate during processing to ensure that the metal plate will not shift or shake during processing, but also greatly facilitate the smooth transportation of the metal plate, so that the metal plate can be pushed forward in the processing flow, thereby continuously processing the metal plate and avoiding slowing down the processing efficiency due to loading and unloading; by flexibly adjusting the height of the movable frame, the device can accurately adapt to metal plates of different thicknesses, which can meet the thickness requirements of various metal plate processing; and the drive motor built into the roller is a major highlight, which can stably and slowly transport the metal plate forward with the help of the belt; in summary, the device, with its unique structural design, achieves multiple goals such as high-efficiency processing, adaptability to metal plates of various thicknesses and stable transportation, while also having the advantages of simple structure, easy maintenance and low cost;

[0012] (2) In the metal plate processing process, by precisely changing the position of the mounting box and clamping plate, the device can effectively meet the processing needs of metal plates of different widths, thereby expanding the applicability of the device. In this process, the cooperation between the threaded rod and the slider plays a key role. This design can overcome the limitations of the traditional pin and locking structure in adapting to metal plates of various widths, and avoid problems such as unstable connection or incompatibility caused by width differences. At the same time, compared with the method of adjusting by relying solely on the screw and screw hole, this cooperation mechanism greatly improves the adjustment efficiency, reduces the operation time and labor costs, and enables the device to complete the adjustment action more quickly and accurately when facing metal plate processing tasks of different widths, ensuring the continuity and efficiency of the processing process.
