Problems solved by technology
For example, in order to ensure the accuracy of electronic belt scales, the tobacco industry needs to calibrate all belt scales once a day before production. The calibration work of each electronic belt scale requires about 3 to 4 people, and because the weight calibration is done intermittently, it cannot be completely Simulate the state of continuous feeding in actual production, and due to the complicated working conditions of the electronic belt scale, the efficiency of manual weight calibration is very low

Description
technical field [0001] The invention relates to an automatic calibration device for an electronic belt scale. Background technique [0002] Electronic belt scales have a wide range of applications, such as tobacco, chemical, steel, cement and other industries. Calibration is a very important task in the calibration of electronic belt scales. At present, this work is mainly performed manually by placing weights, connecting weights and calibrating. For example, in order to ensure the accuracy of electronic belt scales, the tobacco industry needs to calibrate all belt scales once a day before production. The calibration work of each electronic belt scale requires about 3 to 4 people, and because the weight calibration is done intermittently, it cannot be completely Simulate the state of continuous feeding in actual production, and due to the complicated working conditions of the electronic belt scale, the efficiency of manual weight calibration is very low.
