The assembly for real-time dynamic verification of the electronic belt scale comprises a belt arranged on the electronic belt scale and a cycling chain code device arranged above the electronic belt scale, wherein the cycling chain code device comprises a chain code arranged above the belt, and conveying carrier rollers and weighing carrier rollers are arranged below the belt; weighing scale frames are arranged below the weighing carrier rollers, the cycling chain code device is arranged above the weighing scale frames, and the plurality of weighing carrier rollers are arranged in the running direction of the belt; and a chain code speed measuring device is arranged on the inner side of the cycling chain code device, a belt speed measuring device is arranged on the inner side of the electronic belt scale, and the plurality of weighing scale frames, the chain code speed measuring device and the belt speed measuring device are connected with a weighing instrument through communication cables.

Description

technical field [0001] The invention relates to a real-time dynamic calibration electronic belt scale assembly and a calibration method thereof. Background technique [0002] The working principle of the electronic belt scale is to measure the material weight of a certain section of the belt and the current belt speed, and calculate the instantaneous flow rate based on this, and obtain the belt cargo delivery volume within a certain period of time by time integrating the flow rate. The weight of the material is transmitted to the measuring equipment through the belt. The tension, hardness, and ambient temperature of the belt directly affect the weighing result. These factors (tension, hardness, and ambient temperature of the belt, etc.) have a greater impact on the accuracy of the weighing. The current technical solutions to solve this problem generally use circular chain codes or calibrate the hopper scales and belts, and correct the measurement parameters of the electronic...
