[0002] In the field of metal processing, rolling technology is an important process for manufacturing metal plates, bars and profiles. During the rolling process, precise control of the rolling thickness is essential to ensure product quality and performance. With the development of industrial automation and intelligent manufacturing technology, modern rolling equipment is moving towards higher precision, flexibility and efficiency. This equipment can adapt to the production needs of products of different specifications and quickly adjust the roller spacing to adapt to the rolling of materials of different thicknesses. In addition, the design of the new rolling equipment also takes into account the metal surface treatment to ensure that the surface of the metal plate after rolling is flat and defect-free, meeting the requirements of high quality standards. Therefore, a metal rolling equipment with adjustable rolling thickness is developed.
