Rotary material blocking device

The utility model relates to the technical field of automation equipment, in particular to a rotary material blocking device. Comprising a base, a rotating shaft is axially fixed to the base, the rotating shaft is perpendicular to the base, the rotating shaft is sleeved with a striker plate, the striker plate is parallel to the base, a sensor is arranged on the striker plate, a driving piece is further arranged on the base, and a transmission piece in meshing transmission with a gear is arranged at the driving end of the driving piece. By controlling rotation of the striker plate and movement or stop of the workpieces, when no workpieces are stacked on the machining station, the workpieces can normally work, when the sensor detects the workpieces, the striker plate rotates, the workpieces smoothly pass through, when the workpieces on the machining station are not machined completely, and when the sensor detects the workpieces, the striker plate does not rotate; and the workpieces are prevented from passing th
