Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch processing, and more specifically to an extrusion device for PBAT biodegradable masterbatch. Background Art

[0002] The full name of masterbatch is masterbatch, also called color seed. It is a new type of colorant specially used for polymer materials, also known as 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 made by uniformly loading an extraordinary amount of pigment into the resin. In the process of masterbatch processing, the masterbatch needs to be extruded into shape through an extruder.

[0003] Based on the above, the inventors found that after the existing extrusion device performs the extrusion molding of the masterbatch, the masterbatch is arranged in a strip shape and is transported by a conveying device. The masterbatch strips are not easy to be rolled up in a centralized manner, which is not convenient for subsequent sorting and collection. Therefore, in view of this, the existing structure is studied and improved, and an extrusion device for PBAT biodegradable masterbatch is provided, in order to achieve a more practical purpose.
