Labeling inspection machine consists of weighing module, when the items through the load cell, the load cell records the weight of the size, so that after the analog collection of signals through the conversion needs. Digital signals processed through the microprocessor display, the current display equipment are to apply the liquid crystal display, when the collection of weight data and printing and labeling, these data through the microprocessor can be analyzed, sorted to meet the requirements of the weight of the simplest and most common is the current widely used small electronic scales.
020-34563445Sorting Scale is a high speed, high precision online checkweighing equipment of dynamic weight signal processing system, a wealth of software, electronic and mechanical options, so that this series can meet the requirements of online checkweighing in various industries. Modular design makes the operation and daily maintenance of this series very easy. The components are easy to disassemble and clean with water, imported electrical components, waterproof performance and simple operation surface. It can store 100 kinds of parameters of different weight specifications of materials, which is convenient for operation and use.
Built-in report statistics, reports can be generated EXCEL format, can automatically generate a variety of real-time data reports; U disk can be stored for more than 1 year of statistical data, at any time to grasp the production situation; reserved standard interface, data management is convenient, and can be networked with the PC and other intelligent equipment communication; to achieve centralized control: to achieve a computer/human-machine interface on the centralized control of multiple checkweigher; parameter restoration: to provide factory Parameter recovery function: provide factory parameter setting recovery function.
Checkweigher working principle:
When the material is conveyed to the center of the weighing platform, pressure is applied to the load cell, which undergoes deformation, resulting in a change in impedance, and at the same time a change in excitation voltage is used to output a variable analog signal.
The signal is amplified by an amplifier circuit and output to a special analog-to-digital converter, which is converted into a digital signal for easy processing and output to a proprietary microprocessor for arithmetic control.
This result is output to a display that shows item weight data based on keyboard commands as well as algorithms.
Weighing objects in motion, its dynamic Weighing system consisting of load cells and other components is not a closed-loop automatic control system, but a specialized data acquisition system.
That is, the signal characteristics and quantities given by the dynamic weighing control system are processed according to which the DC component, which is proportional to the mass, is separated from it, so that the current dynamic weighing method can be said to be a method based on signal processing.
