The basic principle of precision sorting scale and screening checkweigher.
The total weight sorting scale adopts the world's best digital display scale control module to carry out high-precision and stable measurement and testing. The steel frame of the total weight scale ensures accurate and stable LCD touch screen computer operation in the middle and late stages of dynamic work. The system, the English-Chinese control panel and the touch screen display are convenient in actual operation, convenient and easy to understand. The powerful data statistical analysis function, records the detection data of each class, selects the offline conveyor belt, and is convenient to maintain the standard total weight of five disk partitions. Can store 10 sets of product data information preset method Outer packaging box specification model (mm): 1145 (L) × 860 (W) × 1440 (H) × total weight: 145Kg. Electronic components (loading sensor, operational amplifier circuit, AD conversion circuit, single-chip circuit, display circuit, computer keyboard circuit, communication interface power supply circuit, adjustable regulated power supply circuit, etc.) are selected to form the basic principle of the sorting scale. The basic concept of the total weight classification scale: the test results show that: when the object is placed on the scale, the pressure is released to the sensor, the sensor causes deformation, and then changes the characteristic impedance; in addition, the use of encouragement measures makes the working standard voltage change, and then Output a transformed differential signal. According to the operational amplifier circuit, the signal can be output to the analog-to-digital converter. The pulse signal that is transformed into easy to obtain is output to the CPU for calculation and solution. The cpu outputs this result to the display screen according to the commands of the computer's keyboard and their operating procedures. Before the result information content is displayed. The scope of application of the material selection scale: It is mainly used for automatic net weight inspection, upper and lower side line identification or net weight classification selection on various automated control packaging lines. It is widely used in the pharmaceutical industry, food, food, health products, Various online high-speed packaging inspection applications for daily chemical products, batteries, light industry, etc. Turnover materials are inspected by checkweighing. After reaching the standard, they will be sent to the genuine conveyor belt. If they are unqualified, they will be loaded and unloaded (or the alarm system is on standby). The product is classified and data analyzed according to the settings, and the feedback signal is automatically adjusted. Feeder machinery and equipment, text display common problem alarm information, a variety of graphical data analysis and display functions.
