Belt Measuring Scale: Technical Analysis of Measuring Accuracy

The measuring accuracy of belt measuring scale is closely related to the structure of the scale frame, and the selection of high-quality materials and scientific design are the primary links to establish accurate measurement. The optimized scale frame is made of high-strength alloy steel or special composite materials. These materials have compression and deformation resistance and can withstand the heavy pressure and frequent vibration of materials during belt operation. Through finite element analysis technology, engineers simulate the stress distribution of the scale frame and accurately calculate the stress conditions of different parts, so as to design the structure in a targeted manner. Add reinforcement ribs or optimize the connection method at key stress points to ensure that the overall deformation of the scale frame is controlled within a very small range during material transportation. This double guarantee from material to design effectively avoids measurement deviations caused by unstable scale frame structure. ​
Innovative design to isolate interference
As an innovative structure to ensure the measurement accuracy of belt measuring scale, the suspended scale frame isolates external interference through a unique design concept. The scale frame uses a special support and hanging system to physically isolate the weighing area from other parts of the belt operation. During the operation of the belt, common factors such as belt deviation and tension fluctuation will interfere with the measurement, but the suspended scale frame makes the weighing area relatively independent, and these interference factors are difficult to be transmitted to the weighing sensor. When the belt deviates, the suspension structure allows the weighing area to adjust adaptively within a certain range, always maintaining accurate perception of the material weight; in the face of changes in belt tension, the suspension design acts as a shock absorber to buffer the impact of tension fluctuations, ensuring that the weight signal collected by the sensor only comes from the material itself, greatly improving the accuracy and stability of the measurement. ​
Exquisite layout for uniform load bearing​
The four-group roller scale frame uses its exquisite layout design to achieve uniform load bearing in the weighing area and ensure accurate measurement. This scale frame reasonably plans the spacing and installation angles of the four groups of rollers to form a stable support surface when the belt passes through the weighing area. When the material is transported to the weighing area, the four groups of rollers can evenly disperse the weight of the material to avoid measurement errors caused by uneven local force. The precise roller installation angle can also guide the material to maintain a stable distribution state on the belt to prevent material accumulation or deviation from affecting the measurement results. The four-roller scale frame is designed with full consideration of the running characteristics of the belt, reducing the friction resistance between the belt and the roller, reducing the vibration interference caused by friction, and cooperating with high-precision sensors to achieve accurate measurement of material weight, providing reliable guarantee for the stable measurement of the belt measuring scale. ​
Perfect coordination of structure and sensor​
The optimization of the scale frame structure does not play a role in isolation, and the coordination with high-precision sensors is the key to achieving accurate measurement. The stable scale frame structure provides a reliable installation foundation for the sensor, reducing the interference of external factors on the sensor signal acquisition; and the high-precision sensor can accurately capture the material weight information transmitted by the scale frame and convert it into accurate electrical signal output. When the scale frame effectively isolates the interference of belt tension changes, vibrations, etc., the sensor can focus on the measurement of material weight, and the two complement each other. In practical applications, the suspended scale frame is combined with a high-sensitivity strain gauge sensor to accurately measure under complex working conditions; the four-roller scale frame is combined with a high-precision piezoelectric sensor to quickly respond to changes in material flow and accurately measure instantaneous weight. The combination of structure and sensor enables the belt measuring scale to maintain measurement accuracy in various industrial scenarios, making it a reliable device in the field of material measurement.
