[0004] Non-ferrous light metal alloy plates, such as aluminum alloy plates and magnesium alloy plates, are partially used for product appearance surfaces. The surface quality requirements for the finished plates are relatively high, and some plates even have mirror requirements. When processing plates, the non-ferrous light metal alloy plate processing line needs to ensure that the plates are fed forward along the center line of the equipment. Therefore, after the plates are loaded onto the rollers, the plate centering action needs to be performed to ensure that the plates are fed along the center line of the production line. The existing feeding roller centering action often slides along the axis of the roller. The centering process is likely to scratch the surface of the plate, affecting the subsequent use of the plate. The problem of easy scratching during the plate centering process needs to be solved urgently. (III) Content of utility model
