In the process of preparing a polymer blend sample, a torque rheometer (internal mixer) is generally used to melt blend a small batch of multi-component materials (resins) to obtain a mixture sample which can be tested and characterized. Because the materials are melted and blended in a closed cavity of the internal mixer, the cavity needs to be opened after internal mixing is finished, the blended materials are scraped out from the cavity wall and a rotor of the internal mixer by using a copper tool, but the high molecular polymer has certain viscoelasticity and fluidity, in the process of scraping the materials, the physical processability of the high molecular polymer and the external force action of a scraping tool can cause the size and the shape of the taken-out blended materials to be irregular, and the materials are difficult to cut after being cooled and solidified at room temperature, thereby causing difficulty in subsequent further processing molding or direct sampling test.

In general, in order to enable the scraped material to be directly used for next processing and forming, a small amount of sampling methods can be adopted for multiple times, but the sampling method is low in efficiency and long in time, and the scraped material is difficult to remove because the sampling quality does not reach the minimum dosage required by next processing and forming (micro extrusion, micro injection molding and plate molding), and the inner wall of a cavity and the surface of the material adhered to a rotor are cooled and solidified. Or when the materials are still in a molten state, the materials are scraped out in a large block and quickly, and after the materials are solidified, the materials have higher surface hardness and larger solidified size, so that the cutting is difficult.
