Automatic stirring and weighing device

The utility model discloses an automatic stirring and weighing device which is characterized in that a buffer frame and a buffer spring are arranged, when the device performs stirring work, acting force is buffered by the buffer spring at the outer end of a buffer rod, the acting force generated by the device during stirring work can be effectively prevented from acting on a pressure sensor, and the pressure sensor is prevented from being damaged. The weighing of the pressure sensor is more stable, and the use stability of the device is improved; through the arrangement of a sliding groove and a limiting groove, a buffer frame and a buffer spring for mobile buffering can be limited, the situation that the use stability of the pressure sensor is reduced due to springback of the buffer spring and the buffer frame is prevented, and cooperative use between the structures of the device is more stable; by installing the PLC, the PLC sets a corresponding weight value, and when stirring raw materials at the inner end
