Problems solved by technology
[0004] At present, the calibration is done by the calibrators simulating the physical (weight) calibration and calibration work. The time interval between each calibration is long. Once the measurement accuracy deviates during use, the calibration cannot be carried out in a timely and rapid manner, which will affect the product quality; and The weight itself will change in weight during use or long-term storage, which will lead to increased tobacco weighing errors
If you want to shorten the time interval for each calibration, the current calibration method of manually moving weights is used. The entire calibration process is inconvenient to operate, the work is labor-intensive, the calibration time is long, the calibration work efficiency is low, and the operation safety is low.
At the same time, the fragments of tobacco material that are spilled during the production process are easy to get stuck between the belt bracket and the area of the weighing unit, affecting the accuracy of the calibration results

The invention discloses a belt weigher weighing error measuring device, and relates to the technical field of tobacco weighing devices. The device comprises a reference platform and a compressed air system, the reference platform is provided with a belt weigher weighing unit, the compressed air system comprises an air storage container storing compressed air and an air outlet nozzle communicated with the air storage container, and the air outlet nozzle is installed towards the reference platform; and the air outlet nozzle sprays compressed air to the belt weigher weighing unit on the reference platform, and the compressed air acts on the belt weigher to enable the belt weigher to display weighing data corresponding to the air acting force. According to the invention, compressed air is used for flushing and spraying the weighing unit of the belt weigher, and then the weight reading is displayed on the belt weigher to replace a weight. The invention further discloses a belt weigher weighing error measuring method which is used for detecting the weighing error of the belt weigher, the detection accuracy is high, and the belt weigher can be guided and adjusted.
Description
Technical field [0001] The present invention relates to the field of tobacco weighing devices, and more particularly to a belt scale weighing error measuring device and a measurement method thereof. Background technique [0002] The tobacco industry, the electronic belt scale is used in the various processes of silk processing, belonging to a common metering device. [0003] During the production process, the flow of water flow, adding fragrance, etc., according to the electronic belt scale weighing, the accuracy of the weighing sensor of the electronic belt scale is high, and the technician also regularly performs the weighing accuracy of the belt scale. Verification and calibration. [0004] At present, the calibration is the calibration person analog physical (weight) calibration calibration, and each of the time intervals of the scales have a long time interval, once the measurement accuracy is deviated during use, it is not possible to quickly and quickly carry out the quali...
