shock! How to detect the load cell failure of the checkweigher like this
In the 20th century, the construction of China's food machinery and weighing equipment manufacturing equipment has achieved rapid development, and many companies that can participate in international competition have emerged in various fields. However, the rapid development of these online weighing equipment depends on the rapid development of China's economy on the one hand, and on the other hand on the competitive advantage obtained by reducing labor and material costs. With the improvement of the automation of food packaging checkweighers, the application of intelligent technology (especially robotics) in the packaging industry has developed rapidly, increasing from 9.5% to 17.4% in the past five years. Robots appear in almost every functional area of u200bu200bthe packaging. With the continuous advancement of intelligent manufacturing machinery technology, it gradually shows the characteristics of accuracy and self-discipline, human-machine integration, induction and recognition, super flexibility, strong learning and self-maintenance capabilities. First of all, when the weight of the belt is at a standstill (the conveyor stops with no load), we can measure the output voltage and excitation voltage of the load cell on the terminal of the instrument and make a judgment based on this. If the measurement result in the box is correct with the measurement result on the top of the instrument, and there is no abnormality in each connection of the load cell, if the belt scale has only one load cell (usually a pressure sensor), we can consider replacing it. For the double-sensor checkweigher machine, remove one of the output wires of the weight sensor from the junction box on the junction box, and only the other weight sensor, you can start the calibration machine, and measure the zero value stability of the calibration machine in the idling state sex.
need huge investment, so it is important to shop with caution.
