Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, and more specifically, to a dry mixing device suitable for an injection molding machine. Background Art

[0002] Before the injection molding machine is processed and produced, it is necessary to fully mix various raw materials in a certain proportion, and feed the evenly mixed raw materials in batches for melting, and then squeeze the melted raw materials into the injection molding machine for production. At present, some mixing devices are equipped with hot air pipes, which can blow hot air into the tank during the mixing process, and dry the raw materials at the same time during the mixing process, but the hot air pipe is generally set on one side of the tank, and the hot air can only dry part of the raw materials near the periphery. The stirring mechanism needs to continuously turn out the raw materials near the center for drying, resulting in low drying efficiency; in addition, some tanks are provided with a discharge pipe at the bottom, and a flap valve is provided at the bottom of the discharge pipe, which is convenient for discharging the raw materials in batches after stirring, but a part of the raw materials will be pre-stored in the discharge pipe, and the stirring mechanism is not easy to turn out the raw materials in the discharge pipe for stirring, resulting in poor mixing effect.
