Raw material mixing device in plastic production process

Abstract

The invention relates to the technical field of plastic production equipment and relates to a raw material mixing device in a plastic production process. A stirring shaft is arranged in a cylinder body of the raw material mixing device and is connected with a stirring motor through a planetary gear; the stirring shaft comprises a screw shaft and a sleeve shaft; the screw shaft and a sun wheel are coaxially arranged at the sun wheel; the sleeve shaft is connected with a planetary carrier; guiding long holes are formed in the side wall of the sleeve shaft along the axial direction; a paddle holder is in threaded connection with the screw shaft; paddle mounting rods extending from the corresponding guiding long holes are arranged on the side wall of the paddle holder; a paddle is arranged at each paddle mounting rod; each paddle is connected with the corresponding paddle mounting rod through a first bearing; premixing device bodies are arranged at the cylinder body and comprise material mixing barrels; a material mixing cavity is arranged in each material mixing barrel; and a material mixing rotary shaft is arranged in each material mixing cavity and is driven by a material mixing motor. According to the raw material mixing device disclosed by the invention, plastic production raw materials can be better stirred and mixed at multiple stages.

Description

technical field [0001] The invention relates to the technical field of plastic production equipment, in particular to a raw material mixing device in a plastic production process. Background technique [0002] Plastics are polymer compounds (macromolecules), commonly known as plastics or resins, which are polymerized from monomers as raw materials through polyaddition or polycondensation reactions. Fillers, plasticizers, stabilizers, lubricants, pigments and other additives. When plastic is processed and produced (granulated), it is necessary to mix the raw materials for plastic preparation and then carry out a series of operations such as kneading, hot cutting, and screening. Whether the mixing of plastic raw materials is sufficient has a great influence on the quality of the prepared plastics. The existing equipment for mixing plastic raw materials basically adopts a single stirring method, which makes the mixing of plastic raw materials. There will be a large number of ...

Whether the mixing of plastic raw materials is sufficient or not has a great influence on the quality of the prepared plastics. The existing devices for mixing plastic raw materials basically use a single stirring method, which makes the plastic raw materials mixed and stirred. There will be a large number of blind spots in mixing, so that the plastic raw materials cannot be mixed well, which will seriously affect the quality of the prepared plastic products
