Adjustable edge grinding machine

The utility model provides an adjustable edge grinding machine which comprises a machine frame, a first driver, a first conveying mechanism, a second conveying mechanism, a supporting frame, a sliding groove, a pressing wheel assembly, a pressing wheel driving rotating shaft, a reverser, a transverse rotating shaft and an adjusting hand wheel. Certain downward force is applied to materials through the pressing wheel assemblies arranged on the supporting frames on the two sides, the materials are pressed and fixed, and the situation that the materials vibrate up and down due to external vibration, so that the edge grinding device is not accurate enough in blunt and poor in blunt effect is avoided; the pressing wheel assembly longitudinally moves on the machine frame, the commutators on the two sides are connected through the transverse rotating shaft, the two ends of the pressing wheel assembly keep horizontally moving on the sliding grooves, and the problems that the height of left-right movement is inconsist
