Abstract
The utility model relates to a packing grading device which comprises a microcontroller. An A/D converter is connected on the microcontroller and connected with a straingauge type transducer converting a weight signal into a voltage signal. A card reader is connected on the microcontroller. The card reader comprises a data collecting unit and a communication unit. A tobacco grade professional keyboard is connected on the microcontroller. The packing grading device is characterized in that the straingauge type transducer can convert the weight signal of tobacco into the voltage signal and then conducts read-write on an RFID tag through the data collecting unit. In addition, the microcontroller controls the card reader to transmit radio wave energy with a certain frequency to the RFID tag on a tobacco frame so as to drive a tag circuit on the RFID tag to send out internal data. The card reader sequentially receives and reads the data and sends the data to the microcontroller for relevant processing, the data are inputted through the tobacco grade professional keyboard, and therefore the grade of the tobacco is assessed. Tobacco weighing, card reading, and input function of grading are combined into a whole, automation degree is high and working efficiency is high.
