Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment, and in particular to an automatic mixing device that facilitates feeding and receiving of materials. Background Technology

[0002] In the production of plastic products, it is necessary to mix and stir different types and colors of plastic granules and additives (such as color masterbatch, fillers, etc.). Currently, factories generally use mixing machines (or blenders) for mixing. The height of the mixing machine is usually about 1.8 meters, and the discharge height is about 60 centimeters. Its drawbacks are: First, inconvenient feeding: When feeding manually, the operator needs to lift the heavy raw material bag to a height of nearly 2 meters. This working height is not ergonomic, not suitable for humanized operation, has high labor intensity, low operating efficiency, and poses safety hazards. Second, inconvenient receiving: After mixing, the discharge port height is usually only about 60 centimeters, resulting in a cramped discharge space. The selection of existing receiving containers is limited, which easily generates dust and material spillage, affecting the working environment and material recovery rate. Utility Model Content
