Description of the main accessories of the weight detection machine1
The hardware of the system mainly includes the following parts: the computer, the signal detection part, the signal conditioning circuit, the data acquisition card part, the control part and the actuator and other parts. (1) Computer: The middle of the entire measurement and control system for data acquisition, data management and control decisions. (2) Signal detection part: mainly refers to two high-accuracy pressure sensors, which are responsible for real-time conversion of the quality signal of dynamic weighing, and transmit the electrical signal obtained after conversion to the data acquisition board part. (3) Signal conditioning circuit: Amplify, encourage, linearize, isolate and filter the signal. (4) Data acquisition card part: including the data acquisition card and its supporting equipment, A/D conversion of the collected data, and transmission to the computer for further analysis and processing; and then the control results output by the computer are converted by D/A, output to the control part. (5) Weighing display control system: The computer processes according to the control setting parameters, obtains the control results through a certain control algorithm, and transmits the control results to the actuator. The weighing display control instrument can display the gross weight, net weight, then one weighing value, and then the difference between one weighing value and the set nominal value. It can also display the total number of weighing pieces, the number of underweight pieces, the number of overweight pieces, and the number of qualified products. The display control system can also transmit a variety of statistical information, and can network useful information to the management computer through the communication interface or print out the report through the printer. (6) Execution removal device: According to the packaging method and characteristics of the inspected item, the removal device can be divided into various methods such as pushing out, tipping and falling, and transferring. Substandard packaging products.
