Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch feeding devices, in particular to a masterbatch feeding device for an injection molding machine. Background Art

[0002] Masterbatch is a mixture of resin and a large amount of pigment or dye with high concentration of color. Masterbatch, also known as color seed, is an aggregate made by uniformly loading an extraordinary amount of pigment or dye into the resin. When processing, a small amount of masterbatch is mixed with uncolored resin to achieve the colored resin or product with the designed pigment concentration. When processing, the masterbatch is mixed and stirred by using a masterbatch mixer. The current masterbatch mixer cannot add materials evenly according to actual needs, which reduces the mixing effect and thus reduces the quality of the masterbatch.

[0003] The existing feeding method is mixed extrusion feeding, which will cause the masterbatch to be mixed unevenly in the stirring extrusion discharge device, and fall together when extruded. During the extrusion process, the masterbatches rub against each other. After long-term use, the extruded plastic is incomplete or sticks to the conveying screw, requiring secondary processing or removal, which increases the workload of the operator.
