Description

Technical Field

[0001] The utility model relates to the technical field of injection molding particle mixing, in particular to a high-efficiency injection molding particle mixing device. Background Art

[0002] The raw materials used for injection molding are plastic particles of various materials. In order to improve product performance during the injection molding process, it is usually necessary to mix plastic particles of various materials or colors, and then use an injection molding machine to perform injection molding. However, the existing mixing method is to pour the particles into a mixer for mixing. The mixer stirs the plastic particles evenly through the internal screw. The entire mixing process takes a long time and the mixing uniformity is poor. In addition, during the long-term stirring of the plastic particles by the screw, the friction between the screw and the plastic particles will generate heat and temperature rise. In severe cases, the plastic particles will adhere to the surface of the screw. Therefore, in order to solve the above problems, an efficient mixing device for injection molding particles is designed. Utility Model Content

[0006] Preferably, the spoiler is fixedly connected to the main shaft through the annular frame, and the spoiler is arranged obliquely corresponding to the outer edge of the mixing hood; the plastic particles fall from the gap between the barrel body and the mixing hood after being thrown by the mixing hood, and the fallen plastic particles are spirally mixed in the lower layer of the barrel body under the drive of the rotating spoiler until they fall to the bottom of the barrel body;

[0007] Preferably, the stirring arm fits the air-permeable net at the bottom of the barrel, and the stirring arm is used to prevent the plastic particles from piling up at the bottom of the barrel;

[0008] Preferably, the diameter of the multiple air holes on the surface of the air permeable net is d, wherein 0.5 mm ≥ d ≥ 0.1 mm; the air holes on the surface of the air permeable net that are much smaller than the diameter of the plastic particles can prevent the plastic from falling, and can also allow the gas to pass through the air permeable net to cool the plastic particles;

By arranging a breathable net at the bottom of the barrel body, the gas passes through the breathable net to cool the plastic particles, thereby achieving the effect of preventing the plastic particles from heating up due to friction.

[0020] The spoiler 3 is fixedly connected to the main shaft 6 through the annular frame, and the spoiler 3 is inclined corresponding to the outer edge of the mixing cover 2; the plastic particles fall from the gap between the barrel body 1 and the mixing cover 2 after being thrown by the mixing cover 2, and the fallen plastic particles are spirally mixed in the lower layer of the barrel body 1 under the drive of the rotating spoiler 3 until they fall to the bottom of the barrel body 1;
