As a high-precision quantitative batching device, multihead weigher is widely used in batching systems with small flow, generally used in batching systems less than 500kg/h. In comparison, the multihead weigher has the characteristics of high control precision, fully sealed design, simple calibration and good stability. Today, Zhongshan Smart weigh will share with you how to improve the reliability and accuracy of the multihead weigher. To make the multihead weigher work better for production, it needs to be improved in detail, that is, how the multihead weigher improves the reliability of metering and the accuracy of control.
The multihead weigher improves the reliability of measurement and the accuracy of control mainly from the following aspects: 1. The multihead weigher selects the appropriate range of the load cell. In some cases, the feeding amount of the multihead weigher is very small, such as 50kg/h. At this time, the sensor needs to have a high sensitivity. If the selected sensor range is too large, the sensor will not be sensitive to weight changes. Errors or even zero flow rates are unavoidable. 2. Try to stay away from places with vibration sources. The impact of vibration on weight is self-evident, especially for irregular vibration sources. Therefore, if possible, install the multihead weigher in a place far away from the vibration source.
2, 3. For the situation that the feeding amount often needs to be adjusted in the feeding process and the adjustment is relatively large, two-way PID control should be adopted. Fine adjustment, so that the feeding amount is stable near the set value. Zhongshan Smart weigh self-developed automatic multihead weigher, multihead weigher, multihead weigher, automatic sorting scale, weight sorting scale for a large number of enterprises in my country to solve the difficult problems in the production and packaging of products, improve product quality assurance, and improve the quality of enterprises. Brand.
