Automatic plate positioner of offset press

The utility model provides an automatic plate positioner for an offset press, which relates to the technical field of offset presses and comprises a workbench, moving components are symmetrically arranged on two sides of the lower end face of the workbench, and bearing plates are mounted on the moving components. The plate feeding device has the advantages that a plate is placed on the workbench, the telescopic component drives the bearing plate to move towards the inner side, the bearing plate moves through the moving assembly, meanwhile, the bearing plate on the other side is driven to synchronously move towards the inner side through the pulling assembly, and then the mounting table drives the positioning frame to move towards the plate; the positioning wheels in the width direction of the plate firstly make contact with the plate, along with clamping of the plate, the positioning frame can rotate on the mounting table to drive the positioning wheel on the other side to clamp the plate in the length direct
