Raw material premixing device and mixing method for plastic production process

Abstract

The invention relates to the field of plastic production, in particular to a raw material premixing device and a mixing method for plastic production technology, including an oblique horizontal cylinder body; the invention rotates around the pipe body by setting multiple sets of stirring rings, and adjacent The two sets of stirring rings turn in opposite directions, so that not only the mixing of the upper and lower layers of raw materials in the inclined horizontal cylinder can be realized, but also the auger blades in the adjacent two sets of stirring rings can rotate in opposite directions to each other, so as to realize the mixing of the inclined horizontal cylinder. Stirring and mixing of the raw materials in the middle of the body and the surrounding raw materials. At the same time, the stirring direction of the raw materials located in the adjacent two groups of stirring rings is opposite, thereby speeding up the mixing of the raw materials, and there is an auger rotating through the tube body, and it is connected with the obliquely set reclining The two cylinders cooperate with each other to realize the mixing of left and right raw materials in the inclined horizontal cylinder, so as to further improve the mixing effect of the inclined horizontal cylinder raw materials, improve the mixing efficiency, and improve the quality of plastics.

Description

technical field [0001] The invention relates to the field of plastic production, in particular to a raw material premixing device and a mixing method for the plastic production process. Background technique [0002] Plastic is a high molecular compound polymerized by polyaddition or polycondensation. It can freely change its composition and shape. It is usually composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. When plastics are processed and produced, the raw materials need to be pre-mixed to prevent insufficient mixing of various raw materials in the molten state, resulting in substandard quality of the resulting plastics. [0003] When the existing plastic raw materials are pre-mixed, different raw materials are usually poured into the mixing drum in different batches, so that the raw materials cannot be mixed quickly and evenly, and at the same time, the raw materials in the mixing drum cannot be effectively ...
