High-precision suspension array belt metering scale

Abstract

The invention relates to a high-precision suspension array belt metering scale, which comprises a plurality of groups of full-suspension scale groups uniformly distributed on a rack of a belt conveyor. Each full-suspension scale group comprises two weighing bridges arranged on the rack on the two sides and a plurality of weighing carrier roller supports are arranged on each weighing bridge. Weighing carrier rollers are arranged on the weighing carrier roller supports, and a bearing beam is arranged between two weighing bridges. Two weighing sensors are arranged on the bearing beam. All the weighing sensors are connected to an integrator. A speed measuring device arranged below the rack is connected with the integrator. The integrator is further connected with an industrial controller. According to the invention, a weighing bridge frame is connected with the weighing sensors in a freely floating mode, while no inhibiting device is arranged. Fewer force transmission links are arranged, and the high-precision suspension array belt metering scale is accurate and reliable in weight measurement and high in measurement accuracy. The high-precision suspension array belt metering scale hasthe advantages of strong load-deflection resistance performance, large bandwidth for adapted belt conveyors, high belt speed and the like. Meanwhile, the weighing bridge frame is simple in structure,convenient to install and free of maintenance. The high-precision suspension array belt metering scale serves as optimal equipment for the measurement of high-precision belt conveyors.

Description

technical field [0001] The invention relates to an electronic belt scale, in particular to a high-precision suspension array belt measuring scale. Background technique [0002] Generally speaking, the accuracy of electronic belt scales is not very high, mainly used for internal measurement control. With the introduction of foreign technology, many professional belt scale manufacturers have been able to produce high-precision electronic belt scales. The high-precision electronic belt scale is generally composed of a scale frame, a speed sensor, a high-precision load cell, a high-precision belt scale control display instrument, etc., and can continuously and dynamically measure solid materials. [0003] Electronic belt scales can be roughly divided into two types: pass-through belt scales and quantitative feeders. The former is suitable for trade settlement, while the latter is mainly for process control, which plays a role in increasing the qualified rate of products. Becau...

Problems solved by technology

[0004] The existing belt metering devices on the market, that is, belt scales are mainly lever-type and single-body scales. One or two load cells are used as pressure reflecting elements, and different belt speeds are integrated through the change of MV voltage to obtain the belt in the belt. The measurement value of the area, the existing domestic belt scale is a single-section scale body measurement, and the multi-point balance method cannot be used as a reflection of the real stress state of the conveyor

And it cannot solve the problem of measurement accuracy caused by the conveyor belt being too long or deviation
