Abstract
A metering device comprises a scale barrel, a weight part, and a shut mechanism. The scale barrel is composed of a stationary box plate and a movable box plate pivotally connecting with each other. At least a weighing platform is provided at an inner side of the movable box plate. The weight part is disposed at a lateral side of the scale barrel to measure the weight of weighed substances sent into the scale barrel. The shut mechanism is disposed at an outer side of the movable box plate and has a moving rod to open or close the movable box plate. When the movable box plate is in a state of closing, weighed substances can be received in the scale barrel. When the weight of weighed substances in the scale barrel reaches to a predetermined value, the movable box plate may open pivotally to admit the weighed substances entering a packing bag.
