Mixing mechanism and low-odor flame-retardant reinforced polypropylene material preparation device

Abstract

The utility model relates to the related technical field of polypropylene material preparation devices, in particular to a mixing mechanism and a low-odor flame-retardant reinforced polypropylene material preparation device.The mixing mechanism comprises a mixing barrel, a servo motor, a material mixing box and a material mixing assembly, according to the polypropylene material mixing device disclosed by the utility model, residual and blockage of a polypropylene material in the mixing barrel are avoided, and meanwhile, under the spiral stirring power of the stirring shaft, the material mixing barrel is not blocked by the residual polypropylene material, so that the material mixing efficiency is improved, and the material mixing efficiency is improved. Blocked raw materials can be spirally conveyed into the secondary mixing box, polypropylene materials are fed into the mixing box to be premixed, processed and fed, the polypropylene materials are mixed before being fed by the polypropylene material preparation device, and a mixing mechanism assembly is prevented from blocking a large number of mixed raw materials under the spiral stirring power of a stirring shaft. The stirring rod in the polymerization kettle can be used for timely mixing propylene and a catalyst.
