[0002] Plastic blending modification refers to the process of physically mixing two or more plastics with different properties into a new type of plastic material to achieve better performance and a wider range of applications. However, existing plastic blending devices have certain inconveniences when used.

[0003] A plastic quantitative blending device is disclosed in the Chinese utility model patent application number: CN202021893162.X. By setting a weighing sensor, the stirring ratio is precisely controlled. On the other hand, by setting a stirring blade with a recessed inner cavity, the reaction modification time is increased during the stirring process, thereby improving the effect, quality and stability of the blending. However, the blending device is not convenient for screening plastic materials when in use. The different masses of the plastic materials are likely to affect the blending effect. In addition, the position of the material put into the blending device is relatively fixed when in use, which is likely to cause material accumulation and difficulty in dispersed blending. For this reason, we propose a plastic blending device. Utility Model Content

A filter mesh plate 17 is welded to the middle of the conveying barrel 8, and the filter mesh plate 17 mainly has a filtering effect on the plastic material.

[0021] The utility model provides a plastic blending device, in which a conveying barrel 8 is arranged to introduce materials in a hopper 11 through a discharge valve pipe 12 when in use, and the plastic materials can be blown by a feeding fan 10.
