At the same time, after the forming machine vibrates, an automatic height measuring device is installed to measure the height of the carbon block in real time. Subsequently, based on the feeding amount of each carbon block and using the measured height, the volume density of the carbon block is accurately calculated, thereby accurately controlling the product quality. The quality of the finished product and the equipment are monitored using existing equipment and monitoring devices. After collecting the data, a corresponding carbon block volume density curve is created on the intelligent display screen to monitor the quality of each block. At the same time, it reduces the measurement and monitoring work of employees and the labor intensity of personnel, achieving automation, data intelligence, and humanization.
