Problems solved by technology

[0002] The working principle of the weighing of the belt scale is that the material to be weighed passes through the belt on the belt conveyor and then weighed. The tightness of the belt and the hardness of the belt directly affect the weighing result. Due to the tension of the belt on each belt conveyor and the belt itself The softness and hardness of the belt scale are different, especially the softness of the belt is changed by the influence of the external environment temperature. These factors lead to poor stability of the measurement accuracy of the belt scale.
[0003] The poor stability of the measurement accuracy of the electronic belt scale is the main reason for the low weighing accuracy of the belt scale since the electronic belt scale.
At present, the existing technology solves this problem by regularly performing material calibration or simulation calibration. Since material calibration or simulation calibration is carried out regularly, the measurement accuracy is affected by the change of belt hardness in the daily use of the belt scale. Changes cannot be adjusted and compensated in time, resulting in poor measurement accuracy; in addition, regular material calibration or simulation calibration is time-consuming, inconvenient, and costly

Embodiment

[0025] Test conditions: belt width: 650mm; belt speed: 1m / s;

[0026] Step 1: When the belt scale is calibrated, the ambient temperature is 27°C; the weighing instrument 7 records the range calibration number after the belt scale is calibrated as E; in the case of an empty belt, the front weighing scale frame 1 and the rear weighing Scale frame 2 respectively measures the weight value of the same empty belt, records and calculates:

[0027] Front weighing scale frame 1: Measure the weight value of the empty belt 60.42kg

[0028] Rear weighing scale frame 2: Measure the weight value of empty belt 54.49kg

[0029] Empty belt weight error = (weight value of empty belt measured by rear weighing scale frame 2 - weight value of empty belt measured by front weighing scale frame 1) / weight value of empty belt measured by rear weighing scale frame 2

[0030] Empty belt weight error = (54.49-60.42) / 54.49 = -10.88%

[0031] Step 2: When the belt scale is running normally and the zero...

Abstract

The invention discloses a high-stability electronic belt scale and a stability compensating method thereof. The electronic belt scale comprises a front weighing scale rack (1), a back weighing scale rack (2), a weighting instrument (7) and a speed sensor (8), wherein output signals of each weighting sensor in each of the front weighing scale rack and the back weighing scale rack are respectively sent to the weighting instrument (7). According to the stability compensating method, when the belt scale is in calibration and normal operation zero adjustment under the condition of an empty belt, the weighting instrument (7) respectively detects and calculates the weight error, of the same empty belt, detected by the front weighing scale rack and the back weighing scale rack at the same time, the deviation error is obtained through the weight error, the range calibration number is obtained through the biased error, and the amended range calibration number is used for weighting, so that the influence on measuring accuracy caused by hardness change of the belt is compensated, and the stability and the weighing accuracy of belt scale weighing are ensured. Meanwhile, normal use of the belt scale cannot be influenced, the use is fast and convenient, the cost is low, and the project realization is facilitated.

Description

technical field [0001] The invention relates to a high-stability electronic belt scale and a stability compensation method thereof, belonging to the technical field of automatic weighing instruments. Background technique [0002] The working principle of the weighing of the belt scale is that the material to be weighed passes through the belt on the belt conveyor and then weighed. The tightness of the belt and the hardness of the belt directly affect the weighing result. Due to the tension of the belt on each belt conveyor and the belt itself The softness and hardness of the belt scale are different, especially the softness of the belt is changed by the influence of the external environment temperature. These factors lead to poor stability of the measurement accuracy of the belt scale. [0003] The poor stability of the measurement accuracy of the electronic belt scale is the main reason why the weighing accuracy of the belt scale is not high since the electronic belt scale....
