The rapid test reflects the quality of the mixed rubber through four indicators - "sulfur change, Mooney, specific gravity, and hardness". These four indicators require cutting samples of different sizes from the sample for testing. However, the existing prototype machine uses a separate tool to cut the sample according to the test sample required by the rubber material, which is inefficient, or uses scissors as a tool, but scissors are slow and labor-intensive.
