The characteristic of the on-machine mixing ring screw of the sheet extruder is that the mixing element is installed at the metering section, which mainly plays the role of mixing and homogenization. Based on mechanical manufacturing process considerations, there are generally two structural forms, namely pin type and barrier type. The pin-type mixing element makes full use of the diversion effect of the pin during the plasticization process. During the diversion process, the tiny pieces that have not been plasticized in the previous section will continue to absorb heat from the molten material, thereby making the entire molten material The temperature decreases. When the plastic passes through the pins, the solid phase in the material is crushed and refined, and the melting time is shortened. And due to multiple mixing, plasticized melt can be obtained. This structure is more suitable for raw materials that require high temperature control and require a small temperature rise during processing. Such as transparent materials, etc. In the design, attention should be paid to the selection of parameters such as the number of pin positions and the circulation area. During the plasticizing process, the barrier-type mixing element uses the shearing effect of the barrier ribs between the feed chute and the discharging chute on the material to further homogenize the remaining unplasticized tiny fragments, and at the same time the material can also be mixed. With this structure, the material should contain a certain amount of solid phase material before entering the mixing section to maximize the efficiency of this element. Its color mixing and plasticizing effects are relatively good, but for some products with high transparency or raw materials with poor thermal stability, attention should be paid to the parameter selection of the mixing components.
