Abstract

The invention relates to calibration device of an electronic belt scale. The calibration device comprises a belt periphery fixed steel frame, a carrier roller, a belt, a weigh scale frame, a standard calibration check rod support I, a calibration check rod support II, a return belt, a weighing sensor, a speed sensor, a signal processing and measuring meter, a computer and standard calibration check rods. An electronic belt scale weighing device is fixed through the belt periphery fixed steel frame, the belt is loaded on the carrier roller, the weighing sensor is fixed below the weigh scale frame, and the speed sensor is arranged on the return belt. A signal output end of the speed sensor is connected with the signal processing and measuring meter, and the signal processing and measuring meter is connected with the computer. The standard calibration check rod supports are arranged on the periphery fixed steel frame and the weigh scale frame, the standard calibration check rods can be arranged on the standard calibration check rod supports, and therefore the calibration device is convenient and capable of saving a great deal of manpower and enlarging generality of a check device. In addition, the calibration device can be used for calibration in multiple points, and is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to a calibration device for an electronic belt scale. Background technique [0002] When the electronic belt scale is installed on site, or after a period of use, in order to ensure the accuracy of measurement, it must be calibrated. In "Calibration Method of Electronic Belt Scale", "Three Calibration Methods of Electronic Belt Scale" and other papers, the following three calibration methods are often used: hanging code calibration, chain code calibration, and physical calibration. These calibration methods are to compare whether the cumulative value of mass display on the instrument is equal to the real value of these materials; if not, correct it until the error between the two is less than the industry-specified index. [0003] In the production of actual enterprises, one method of physical calibration is to gradually add accurately known quantitative materials to the conveyor belt, and finally compare the difference between t...
