[0002] Plastic can be made into various objects, such as cups, shells, and plastic bags. In the plastics manufacturing industry, a large quantity of bagged plastic granules is needed. Previously, this was done manually by tearing open the packaging bags and pouring the granules into the processing equipment. Some companies also used unpacking machines to tear open the packaging bags and pour the granules into a feed trough, which was then transported to the processing equipment. However, because the material is stored in the bags for a long time, it is easily affected by external factors and clumps together, resulting in the plastic granules not meeting the feeding requirements of the processing equipment. Furthermore, different sizes of plastic granules have different uses, and existing unpacking machines cannot quickly classify the granules and feed the appropriate granules in a timely manner, affecting production efficiency. Therefore, we need to propose a plastic granule unpacking and feeding device. Utility Model Content
