Description

TECHNICAL FIELD

[0002] The plastic mixer is a mixing device specially designed for plastic raw materials (such as particles, powders, recycled materials, etc.), which belongs to the subfield of mixers. Its core function is to uniformly mix plastic raw materials through stirring, shearing, heating, etc. It may also have additional functions such as drying, coloring, and modification. The filling device is responsible for accurately and uniformly transporting the raw materials to be mixed from the storage container to the feeding port of the mixer.

[0003] In the prior art, such as a filling device of a baby milk powder filling machine, the powder is fed from the storage bin to the discharge pipe through the anti-blocking mechanism, effectively preventing the accumulation and blockage of the powder, improving the work efficiency, and the powder is poured into the powder tank along the circumference through the rotating mechanism, making the powder in the powder tank more uniform, and achieving the ideal effect.

[0004] In order to solve the problem that the existing equipment is prone to blockage of the discharge port during the filling process, affecting the filling speed, the anti-blocking mechanism is used to feed the powder from the storage bin to the discharge pipe;
