Problems solved by technology

This has the disadvantage that the electronic belt scale provides little weighing information, which is not conducive to monitoring and application.
In addition, the fully suspended single roller weighing unit of the electronic belt scale that makes up the metering system has a fixed structure in which the connection between the roller bracket and the load cell is fixed, and it is inconvenient to adjust during installation. This structure is installed on the scale body. There will be a certain internal stress in the future, and sometimes the internal stress cannot be released well, and it is easy to cause over-positioning, which will affect the accuracy of the final measurement result of the belt scale

Embodiment Construction

[0012] Below in conjunction with accompanying drawing, one embodiment of the present invention is further described:

[0013] As shown in the figure, the multi-accumulation electronic belt scale is composed of a plurality of groups of weighing units 12 , accumulators 10 , and speed sensors 11 , which are evenly distributed and fixedly installed on the conveyor frame 6 . Each group of weighing units 12 is mainly composed of idler bracket 1 , support body 2 , load cell shield 3 , load cell 4 , load cell bracket 5 , tension bolt 7 , limit bolt 8 , and limit body 9 . There are at least two groups of weighing units 12, figure 1 4 groups are shown. The multiple groups of weighing units 12 may also be 3 groups, 5 groups, 6 groups, 7 groups or 8 groups, etc. according to actual needs. There are two load cell brackets 5 for each group of weighing units 12, which are respectively fixed on the conveyor frame 6 on the left and right. In order to increase the fixing rigidity of the load...

Abstract

The invention relates to a multi-accumulation electronic belt scale, which is suitable for on-line precise and reliable weighting measurement of materials continuously conveyed by a belt conveyor. The multi-accumulation electronic belt scale comprises a plurality of groups of weighting units, an accumulator and a velocity sensor, wherein the accumulator accumulates and combines multiple paths of weighting signals and velocity signals of the velocity sensor into a plurality of groups of accumulation so as to perform the weight measurement and display control of a group of main accumulation and more than two groups of auxiliary accumulation on the electronic belt scale. Each weighting unit of the belt scale is a full suspended weighting unit, and the belt scale can simultaneously display the plurality of groups of accumulation, and has redundancy backup function, high reliability and accurate measuring precision; the weighting unit has simple structure and wide applicable bandwidth range; the sensor has no over-positioning; a sensor bracket has firm structure; and the multi-accumulation electronic belt scale has simple and easy installation and debugging, small maintenance workload, long service life and comprehensive practicability.

Description

technical field [0001] The invention relates to a multi-cumulative electronic belt scale, which is especially suitable for accurate and reliable online weighing and measurement of materials continuously conveyed by a belt conveyor. Background technique [0002] At present, electronic belt scales used for continuous weighing of materials on belt conveyors have various structural forms such as single lever, double lever, and full suspension; these electronic belt scales have a single independent measurement when they are used on the conveyor, and there are also two Each one forms a pair of measurement, and there are multiple single scales to form a measurement system for measurement. At present, the measurement system of this electronic belt scale adopts the measurement method of combining all weighing signals into the accumulator, or the measurement method of entering the weighing signals of each load cell into the accumulator independently for cumulative operation. These two...
