[0002] The full name of masterbatch is masterbatch, also called color seed. It is a new type of colorant for polymer materials, also called pigment preparation. Masterbatch is mainly used in plastics. Masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate obtained by uniformly loading an extraordinary amount of pigment in the resin. It can be called a pigment concentrate, so its coloring power is higher than the pigment itself. In the preparation process of masterbatch, after granulation, it needs to be circulated and dried. A material conveying device is needed in the circulated drying process. However, the current material conveying device for the circulation drying process of plastic masterbatch does not have a heating function, resulting in the inability to dry the material during the conveying process, and does not have a cleaning function, resulting in the need for manual cleaning, which is very troublesome. For this reason, we propose a material conveying device for the circulation drying process of plastic masterbatch. Utility Model Content
