Problems solved by technology

[0003] The weighing structure of the existing electronic belt scale is a trunnion structure. In order to reduce the torque interference during rotation, an automatic self-aligning bearing is used. When the material is unbalanced, the entire scale frame tends to automatically find the center of rotation, resulting in Tilting, the force of the load cell is also at an angle with the vertical direction, which cannot fully reflect the quality of the actual material flowing through it instantly, resulting in the weighing accuracy hovering at ±0.5%, which cannot be further improved

Abstract

The invention relates to a high-precision electronic belt scale. The belt scale comprises two scale bodies and a weighing instrument which are sequentially arranged in a conveying direction of a beltconveyor, any scale body comprises a base fixedly connected to a rack of the belt conveyor, four weighing sensors distributed on the base in a matrix mode and a scale frame connected with the four sensors, and the weighing sensors of the two scale bodies are connected with the weighing instrument. Through structural improvement of the base and reasonable layout of the four weighing sensors on eachscale body, structural stability of the base is improved, problems of base inclination and center-of-gravity shift of the scale bodies due to deviation of a conveying belt are solved, each weighing sensor can work independently and stably, and therefore measurement precision can be effectively improved.

Description

Technical field: [0001] The invention relates to a high-precision electronic belt scale. Background technique: [0002] The basic working principle of the electronic belt scale is to sense the quality signal of the material passing through the load cell, combined with the belt line speed signal sensed by the speed sensor, and calculate the two signals through the totalizer, and finally obtain the mass of the material flowing through the belt scale , Based on this, trade settlement is carried out, and it is mainly used in docks, power plants, mixing stations, ingredients in various industries, etc. It is an indispensable measurement equipment for the national economy. [0003] The weighing structure of the existing electronic belt scale is a trunnion structure. In order to reduce the torque interference during rotation, an automatic self-aligning bearing is used. When the material is unbalanced, the entire scale frame tends to automatically find the center of rotation, result...
