Method for monitoring durability of electronic belt scale

Abstract

The invention discloses a method for monitoring durability of an electronic belt scale. The characteristic that the tension of a belt on the tail of a belt conveyor is small, and the tension of a belt along the position close to the head direction of the belt conveyor is larger is utilized, two sets of independent weighing loaders are arranged, due to the fact that the arranged weighing loaders are arranged at the different positions of the belt conveyor, when the same materials pass through the weighing loaders, the influences of the tension of the belt on the detected material weight are different, and therefore the weight difference value of weighing materials of the two sets of weighing loaders can be obtained. The weight difference value is compared with the weight difference value obtained in the correcting process in real time, if the value exceeds a certain error, the external environment, such as hardness and tension, of the belt is changed, the range calibration number of a belt scale instrument is corrected in time, and the accurate metering is ensured.

Description

technical field [0001] The invention relates to a durability monitoring method of an electronic belt scale, belonging to the technical field of dynamic weighing. Background technique [0002] The poor measurement accuracy and durability of electronic belt scales is the main reason that has affected the low accuracy of belt scales for many years. The softness of the belt directly affects the weighing results. Because the belt tension on each belt conveyor and the hardness of the belt itself are different, especially the belt hardness is changed by the influence of the external environment temperature. These factors lead to belt scales Measuring accuracy is poor in durability. At present, the current technology to solve this problem is to carry out material calibration or simulation calibration regularly. Since the measurement deviation cannot be adjusted in time due to regular calibration, the measurement accuracy is poor, and the material calibration or simulation calibrati...

[0002] The poor measurement accuracy and durability of electronic belt scales is the main reason that has affected the low accuracy of belt scales for many years. The softness of the belt directly affects the weighing results. Because the belt tension on each belt conveyor and the hardness of the belt itself are different, especially the belt hardness is changed by the influence of the external environment temperature. These factors lead to belt scales Poor measurement accuracy and durability

At present, the current technology to solve this problem is to carry out material calibration or simulation calibration regularly. Since the measurement deviation cannot be adjusted in time due to regular calibration, the measurement accuracy is poor, and the material calibration or simulation calibration is time-consuming, inconvenient and expensive.
