Description

[0001] The utility model belongs to the technical field of thermoplastic powder processing, in particular to a thermoplastic powder processing mixing barrel. Background Art

[0002] In the process of thermoplastic powder processing, it is necessary to mix a variety of raw materials evenly before molding. In order to achieve the effect of uniform mixing, it is usually necessary to use a thermoplastic powder processing mixing barrel. The mixing barrel usually adopts a closed structure and has a set of forced rotating mixing parts inside to ensure that the raw materials are fully mixed. By using a thermoplastic powder processing mixing barrel, the efficiency of thermoplastic powder processing and product quality can be improved.

[0003] In the prior art, a Chinese patent with publication number CN212142333U discloses a plastic powder mixing barrel, which is powered by a rotating motor. The rotating motor can drive the auger blade and the inclined plate to rotate, thereby stirring the plastic powder in the inner cavity of the processing barrel, and controlling the hydraulic rod to contract so that the rubber inclined plate contacts the inner wall of the processing barrel, thereby avoiding the appearance of dead corners; the powerful exhaust fan of the dust suction mechanism is turned on to draw air into the liquid storage box, so that a negative pressure is formed in the inner cavity of the barrel, thereby preventing dust from flowing out with the air, and phenolic resin is easily soluble in alcohol, thereby preventing its powder from flowing out; the blades of the cleaning mechanism can rotate due to the suction force of the powerful exhaust fan, thereby driving the brush to rotate, thereby avoiding the filter from being completely blocked; the plastic powder mixing barrel can not only stir and mix to avoid the appearance of dead corners, but also suck the air to prevent it from flowing out and affecting the environment.

[0004] However, the above-mentioned prior art only uses a set of spiral blades extending into the mixing barrel to stir and mix the materials. The stirring structure of this method is relatively simple, and can only perform simple mixing processing on the raw materials. The mixing uniformity effect is general, and the mixing efficiency is low. Moreover, if the thermoplastic powder is mixed with other coatings, it is not convenient to manually clean the inner wall.
