The invention relates to the technical field of glutinous rice cake processing devices, and discloses a glutinous rice cake processing device based on reciprocating secondary hammering acting force and a use method. The glutinous rice cake processing device comprises a bottom plate, side plates are fixedly connected to the left side and the right side of the top of the bottom plate, a top plate is fixedly connected to the tops of the side plates, a pressing cylinder is fixedly connected to the top of the bottom plate, and left and right buffering extrusion mechanisms are arranged on the left and right sides of the inner wall of the pressing cylinder. The glutinous rice cake processing device solves the problems that in the hammering process, only single reciprocating hammering is adopted, although manpower is saved, glutinous rice cakes cannot become soft after being hammered, and meanwhile, the flexibility of the glutinous rice cakes can be damaged due to excessive force. According to the device, manual operation is simulated through reciprocating secondary hammering operation, so that manpower is saved, in the operation process, secondary slightly light hammering can be performed after primary heavier hammering, the glutinous rice cakes can become soft after being hammered through reciprocating operation, meanwhile, the flexibility of the glutinous rice cakes cannot be damaged, and the glutinous rice cakes are more attractive in the making process.
