Problems solved by technology

Therefore, the biggest problem with measuring curves with the function solving method is that there are n calibration points to generate n measurement curves, and each measurement curve has one thing at the other, so the single-point calibration method cannot solve the influence of random errors

Abstract

The invention relates to a high-precision electronic belt scale and a weighing algorithm of the same. A tensioning structure of the traditional electronic belt scale cannot well maintain constant tension of a belt, and is easy to result in insensitive weighing. The high-precision electronic belt scale comprises a carrier roller, the belt and a motor which are arranged on a machine frame, and is characterized in that: the carrier roller comprises a weighing carrier roller, a primary carrier roller and a secondary carrier roller, the primary carrier roller and the secondary carrier roller are arranged at two ends of the belt, the primary carrier roller is connected with the motor, a speed sensor is connected at the outer part of the secondary carrier roller, a fixed rod is arranged at the lower part of the secondary carrier roller, a steel rope surrounds the secondary carrier roller and the fixed rod in sequence, and is connected with a counterweight block, one end of the steel rope is fixed, a weighing sensor is arranged at the lower part of the weighing carrier roller, and the weighing sensor, the motor and the speed sensor are connected with a controller. In the invention, the load of the weighing sensor can be adjusted to be zero through adjusting the counterweight block, so that the sensitivity of the electronic belt scale is increased; and the weighing sensor only receives a vertical force, and does not receive a tangential force produced during the operation of the belt.

Description

Technical field [0001] The invention relates to an electronic belt scale for dynamic continuous weighing, in particular to a high-precision electronic belt scale for flow measurement and calculation in the tobacco production process and its weighing algorithm. Background technique [0002] The measurement of the electronic belt scale is to measure the linear distribution density instead of the volume distribution according to the flow. The instantaneous flow of the belt is calculated as follows: Q(t)=q(t)v(t)(kg / h). Where q is the weight per unit length of the weighing section, and v is the belt running speed. The flow rate of a belt scale is the product of speed and weight, so the accuracy of the belt scale is determined by speed and precision. The tension structure of the existing electronic belt scale cannot keep the belt tension constant, which easily leads to insensitive weighing. In addition, there is a lack of belt deviation correction system. When the belt is corrected,...
