The invention discloses a novel automatic plate shearing machine. The novel automatic plate shearing machine comprises lower stand columns, a base, a lower cutter and an upper cutter, the lower standcolumns are welded to the lower portion of the base, a lower bottom plate is welded between the lower stand columns, the upper portion of the base is connected with upper stand columns, an upper top plate is arranged above the upper stand columns, a mechanism used for cutting is arranged on the upper top plate, a feeding roller and a feeding belt are arranged on the front half portion of the base,a discharging roller and a discharging belt are arranged on the rear half portion of the base, the lower cutter is mounted in the middle of the base, a sheave mechanism is arranged at the left end ofthe base, a large pulley, a small pulley and a synchronous conveying belt are arranged at the right end of the base, and a receiving device is arranged behind the base. According to the design scheme, automatic cutting production of the equal-width plates is achieved, manpower and production time are greatly saved, production efficiency is improved, the width of the sheared plates is convenientlyadjusted, workpieces can be prevented from being damaged due to large impact during material receiving, and the advantages of being stable in transmission process and cutting process and the like areachieved.
