Main accessories of checkweigher
The following checkweigher machine manufacturers explain the main parts of the checkweigher that the hardware system is the physical basis of the entire measurement and control system. According to the requirements of the function of the measurement and control system, the hardware system is constructed and optimized. The hardware of the system mainly includes the following parts: computer, signal detection part, signal conditioning circuit, data acquisition card part, control part and actuator and other parts. (1) Computer: The middle of the entire measurement and control system for data acquisition, data management and control decision-making. (2) Signal detection part: mainly refers to two high-accuracy pressure sensors, which are responsible for real-time conversion of the mass signal of dynamic weighing, and transmit the electrical signal obtained after conversion to the data acquisition board part. (3) Signal conditioning circuit: Amplify, excite, 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 section. (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 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 deliver a variety of statistical information, and the useful information can be networked to the management computer through the communication interface or the report can be printed out through the printer. (6) Execution rejection device: According to the packaging form and characteristics of the inspected items, the rejection device can be divided into various methods such as pushing out, tipping and dropping, and handling. Packaging the product. manufacturers tell you that checkweighers are mainly used for automatic weight detection, upper and lower line discrimination or weight classification selection on various automated packaging lines, and are widely used in online high-speed packaging in pharmaceutical, food, daily chemical, battery, light industry and other industries.
