Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic processing technology, specifically to a quantitative dispensing device for plastic granules. Background Technology
[0002] After processing, plastic granules need to be quantitatively sieved in batches using a metering device on the feeding funnel to prevent accumulation. The sieved granules then flow through a sealed discharge pipe into corresponding granule boxes for further packaging. The advantages are simple structure, low cost, and suitability for materials with good flowability. However, during quantitative packaging, gaps between the plastic granules and the friction between them can result in large voids, affecting packaging accuracy and leading to significant weight variations in each batch.
