For example, the elastic member 34 may include springs, which may be arranged in three groups. For example, further, the springs may be provided in a plurality and parallel arrangement to each other, which can provide a greater force. Here, that is, the material enters through the pressing space, and sand making is achieved under the pressing and shearing actions of the movable roller 32 and the fixed roller 21.
Wherein, with respect to the rotating shaft 35, the connection point between the elastic member 34 and the mounting seat 31 is located at one side of the rotating shaft 35 away from the fixed roller 21, the rotating shaft 35 is used as a lever fulcrum of the mounting seat 31, the elastic member 34 is used as a proximal stress point of the mounting seat 31, and the movable roller 32 is used as a distal stress point of the mounting seat 31.
