Plate strip side edge pressing device

A plate and strip side edge pressing device comprises a machine frame, a supporting shaft, a main shaft and a main shaft lifting mechanism, the supporting shaft is installed on the machine frame, the main shaft is installed on a lifting frame, the lifting frame is arranged on the machine frame and connected with the main shaft lifting mechanism, the main shaft lifting mechanism is installed on the machine frame, and an edge pressing sleeve is arranged on the main shaft. The split and sheared plate strip is conveyed to the supporting shaft from the previous procedure, the main shaft lifting mechanism is started to drive the main shaft to descend, the edge pressing sleeves are pressed on the two side edges of the plate strip, the main shaft and the supporting shaft are conveyed forwards along with the plate strip to passively rotate, and the edge pressing sleeves flatten edge burrs and slight turnups generated after shearing on the plate strip. According to the utility model, the operation requirement of a plat
