Description

Technical Field

[0001] The utility model relates to the technical field of intelligent weighing platforms, and in particular to an intelligent weighing platform calibration device. Background Art

[0002] Weight scales need to be inspected and calibrated for accuracy before leaving the factory to prevent defective products from entering the market. Currently, weight scales are calibrated mostly by using standard weights to verify and calibrate their no-load, minimum weighing, maximum weighing and other load points. However, various weights of different specifications are needed to support the entire verification and calibration process, which requires staff to frequently replace weights. Weights that are used for a long time will inevitably wear out, which may cause deviations in the weight quality and affect the accuracy of the calibration.

The weight scale metrology calibration device, by providing an electric hydraulic rod, a calibration component, an anti-skid component, a pressure sensor, a display screen, an adjustment component and a universal wheel, avoids the inevitable wear of the weights used for a long time, thereby ensuring the accuracy of calibration, and rolling instead of moving makes it more convenient and labor-saving for users to use the calibration device, thereby improving the practicality of the weight scale metrology calibration device.

The device moves the calibration platen manually, and the moving process is cumbersome, which increases the labor intensity of the staff. At present, no effective solution has been proposed for the problems in the relevant technology. Utility Model Content
