Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a mixer for preparing plastic barrels which can automatically mix and stir masterbatch plastics. Background Art

[0002] Plastic barrels are usually made of plastic materials such as polyethylene and polypropylene. They are light in weight and easy to carry and transport. They are corrosion-resistant and can withstand the erosion of various chemicals. They are not easy to break and are more durable and safer than materials such as glass.

[0003] During the processing and preparation of plastic barrels, masterbatches are usually added to the plastic to color it. Masterbatches are a type of colorant that can give the plastic a variety of rich colors. Masterbatch plastics have the characteristics of uniform and stable color and are not easy to fade or discolor. After the masterbatch is added to the plastic, the plastic and masterbatch need to be evenly and gently stirred by a blender.
