Raw material mixing equipment for flame-resisting and environment-friendly polylactic acid plastic production

Abstract

The invention discloses raw material mixing equipment for flame-resisting and environment-friendly polylactic acid plastic production, and relates to the technical field of the polylactic acid plasticproduction. The raw material mixing equipment comprises a mixing barrel, an electric motor and a discharge pipe. A base is installed below the mixing barrel, feeding ports are formed in both sides above the mixing barrel, the electric motor is installed in the upper middle portion of the mixing barrel, a main rotating shaft is fixedly arranged under the electric motor, and the discharge pipe is disposed at the bottom of the mixing barrel. A micro motor is welded to the outer side of the main rotating shaft, and stirring blades are fixedly arranged at the top end of the micro motor. Brushes are mounted on the right sides of the stirring blades, auxiliary rotating shafts are welded to both sides of the main rotating shaft, stirring rods are fixedly arranged on the outer sides of the auxiliary rotating shafts, fixing brackets are disposed on the outer side of the mixing barrel, damping springs are mounted in the fixing brackets, and fixing rings are fixed to the top ends of the fixing brackets. The raw material mixing equipment has the beneficial effect that the raw material mixing equipment facilitates the improvement of the efficiency of stirring and mixing of raw materials by arranging the main rotating shaft and the auxiliary rotating shafts.

Description

technical field [0001] The invention relates to the technical field of polylactic acid plastic production, in particular to a flame-retardant and environment-friendly polylactic acid plastic production raw material mixing equipment. Background technique [0002] Polylactic acid, also known as polylactide, is a polymer obtained by polymerizing lactic acid as the main raw material and belongs to the polyester family. The source of polylactic acid raw materials is fully renewable, the production process is pollution-free, the product can be biodegraded, and it can be recycled in nature. It is an ideal green and environmentally friendly polymer material. Adding a synergistic mixture of at least one common flame retardant to polylactic acid can make polylactic acid have flame retardant properties, so mixing equipment is needed to mix and stir the raw materials of polylactic acid plastics. [0003] A plastic raw material mixing device disclosed in the Chinese invention patent app...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of raw material mixing equipment for the production of flame-retardant and environment-friendly polylactic acid plastics, so as to solve the problem that the plastic raw material mixing device proposed in the above-mentioned background technology cannot perform multi-directional stirring, and the raw material stirring efficiency and mixing degree are relatively low. And there is no corresponding cooling structure, the plastic raw materials may generate high temperature due to frictional heat during the mixing and stirring process, and there may be a problem of raw material accumulation at the discharge port causing the blockage of the discharge
