What is the principle of the online weighing machine? Briefly describe the accuracy of the automatic weighing machine
The online weighing machine can detect unqualified products, and the online weighing machine can replace manual sampling inspection on the production line. The editor has compiled the principle knowledge of the weighing machine and understands the accuracy of the weighing machine. Only by understanding the principle knowledge of the online weighing machine can the weighing machine be used, so what is the principle knowledge of the online weighing machine? The online weighing machine will release the items that have passed the test, and the weight of the unqualified items will be alarmed, or the sorting organization will push out the conveyor belt. The on-line weighing machine can replace manual sampling inspection on the production line, and can detect all passed items without exception. It is a very suitable measuring equipment to ensure the quality of the produced products. A light conveyor belt is installed on the inspection platform of the online weighing machine. When the tested item passes the inspection platform, the system judges its weight, detects whether it meets the specified weight requirements, and makes a qualified, overweight, or underweight prompt. Or execute the corresponding non-conforming product removal action (according to user needs), and push the nonconforming product out of the production line. The online weighing machine control system has the functions of standard weight detection, counting, alarm and sorting. The automatic checkweigher machine can also have the function of grading and sorting (customization required). When items of different weight specifications are transported on a conveyor belt, the sorting scale can still perform weight identification. The automatic checkweigher machine can be used to control the qualified rate of packaged products, detect whether the package weight meets the standard, determine whether the number of items placed in the box meets the requirements, automatically determine the weight of small packaged foods and classify them, and can also be used to detect quantitative packaging The weight error of the packaging bag on the production line can also be used to detect the abnormal state of the pre-processing procedures on the mechanical processing production line, so as to eliminate unqualified products or implement alarms to achieve the purpose of timely adjustment of equipment and control of product quality. The above knowledge is about the principle knowledge of the online weighing machine. Next, let's take a look at what is the accuracy of the weighing machine. The product to be tested enters the checkweigher machine from the assembly line, and is transported to the weighing section through the Accelerating Section; during the movement of the product to be tested in the Weighing Section, the sensor deforms under the action of gravity, which promotes its impedance When a change occurs, an analog signal is output; it is output to the weighing module analog-to-digital converter through the amplifying circuit, and quickly converted into a digital signal, which is transmitted to the weighing module's processor, and is calculated by the weighing algorithm independently developed by our company ; The weighing module processor amplifies and recognizes the weight signal. If the weight of the product exceeds the preset upper and lower limits, the processor will output a rejection command to the rejection device on the rejection section, thereby removing the unqualified product from the rejection section. (Rejecting Section) is removed. Introduced the principle and accuracy of the online weighing machine, I hope this article will help you understand the online weighing machine quota knowledge.
