Description

Technical Field

[0001] This utility model belongs to the field of plastic production technology, and more specifically, it relates to a mixing device for the production of modified plastics. Background Technology

[0002] Modified plastics refer to plastic products that have been modified from general-purpose plastics and engineering plastics through methods such as filling, blending, and reinforcement, thereby improving their properties such as flame retardancy, strength, impact resistance, and toughness. In the production process of modified plastics, a mixer is required to mix the modified plastics.

[0003] During the mixing process, liquid additives (such as plasticizers and coupling agents) need to be added after the initial mixing of modified plastics. However, the existing method of adding liquid additives usually involves operators manually pouring them into the mixer. This makes it difficult to evenly distribute the liquid additives into the solid raw materials of the modified plastics, resulting in low mixing efficiency and requiring a significant amount of time to mix the liquid additives with the solid raw materials of the modified plastics. This has certain limitations in practical use. Therefore, in view of this, this paper studies and improves the existing structure and its shortcomings, providing a mixing device for modified plastics production, aiming to achieve a more practical application.
