The existing raw material mixing device generally comprises a mixing bin, a stirring shaft and stirring blades. The mixing bin is used for containing raw materials. The stirring blades are arranged on the stirring shaft. The stirring shaft extends into the mixing bin and drives the stirring blades to stir the raw materials in the mixing bin. It is found in use that the existing raw material mixing device can only mix raw materials through the stirring action of the stirring blades, and the mixing efficiency is low.

[0003] However, in the prior art, the stirring blades often stick to the inside of the machine during the process of stirring and mixing raw materials.

In addition, during the mixing process, the raw materials for producing environment-friendly bags are relatively light, and many machines are discharged through the gravity of the raw materials themselves. During the stirring process, the machine interior generates a swirling airflow to prevent the mixed raw materials from being discharged, so that the raw materials are blocked from being discharged, thereby reducing the production efficiency.
