Figure 4 Schematic counting metering device

Two holes through the bottom of the bin , bins of material fall into the holes , each hole a quantitative total amount of the holes on the disc is usually divided into several groups ( shown as three groups ) . When quantitative disc 3 Go unloading station , the material through the discharge chute 4 filling Packing Machine containers.

The device is designed primarily on quantitative structure . To ensure that the material can be smoothly into the hole in the metering disk , often makes quantitative disk 3 is slightly larger than the diameter of the hole diameter of material ( about large 0.5 ~ 1.0mm). Thickness of the disc is slightly larger than the thickness of the material . Bins with transparent front plate more than one material , in order to facilitate observation of material into the hole inside the material situation . This board is the upper surface of the bottom plate and quantitative gap should not be too large to prevent leakage of excess material or slab crushing or scraping broken .

2.2 Scenario Comparison

Several measurement methods discussed above , the volumetric measuring device of simple structure , easy operation, wide adaptability , for the measurement does not require very accurate time , is the preferred way . Relative displacement is measured , weighed metering method to produce high efficiency, high accuracy is also applicable to relatively large changes in the proportion of the material .
