Abstract

The invention relates to a modular structure electronic belt weigher which consists of the following main components: a motor speed reduction unit, a material conveying belt, a weigher body frame, a driving module, a weighing platform module, a driven module and the like, wherein the driving module consists of a driving roller, an automatic correcting device, a guide rail, a fixed carrier roll and the like; the weighing platform module consists of a weighing sensor, a head amplifier, a weighing carrier roll, a guide rail, a weighing platform frame and the like; and the driven module consists of a driven roller, a stretch roll, a guide rail, a fixed carrier roll and the like. Therefore, the problem of stability of performance indexes when the belt weigher operates for a long time is solved. The modular structure electronic belt weigher has the characteristics of simpleness for maintenance and rapidness and convenience for assembly and disassembly and has functions of continuously and dynamically weighing, accumulating the flow, controlling the flow, correcting the deflection of a belt and the like. The modular structure electronic belt weigher can be used as a batcher scale on the production line and can also be used as a target metering scale in the trade settlement process.

Description

technical field [0001] The invention relates to an electronic belt scale with a modular structure, which is used for dynamic weighing of solid bulk materials. Background technique [0002] With the continuous development of dynamic weighing technology, belt scale products are widely used in tobacco, metallurgy, chemical industry, building materials, mining, ports, logistics and other industries. Its dynamic accumulative accuracy has reached the trade settlement requirement of 0.25%. Reliability and other performances have also been greatly improved; however, whether it is a cantilever type, single-lever type or double-lever type belt scale using the principle of leverage, or a suspension-type belt scale without a lever, the scale body is all integrated. The overall structure of the scale body of this structure has the following deficiencies: [0003] 1. Poor long-term stability. After the new equipment has been used for a period of time, due to factors such as belt deviati...
