Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a waste cleaning structure of a rubber Mooney viscosity testing machine. Background Art

[0002] The rubber Mooney viscosity tester is used to measure the viscosity and scorch of raw rubber or mixed rubber. Mooney viscosity reflects the rubber's processing properties, molecular weight, and distribution range. High Mooney viscosity indicates that the rubber is difficult to mix evenly and difficult to extrude; it has a high molecular weight and a wide distribution range. Low Mooney viscosity indicates that the rubber is prone to sticking to the roller; it has a low molecular weight and a narrow distribution range. Excessively low Mooney viscosity results in low tensile strength of the vulcanized product. The Mooney viscosity-time curve also reflects the vulcanization process performance of the rubber.

[0003] The Rubber Mooney Viscosity Tester measures the flow properties of rubber. During the test, a rubber sample is placed on a rotor and heated simultaneously, remaining within the upper and lower mold cavities. As the rotor rotates, it exerts a torque on the cavity material, pushing the rubber layer closest to the rotor to flow. This forces the rubber material within the cavity to react, which is measured using a torque sensor mounted on the motor mount below the cavity to obtain the rubber flow parameters. During the test, the heating causes the rubber to flow, resulting in waste rubber that compromises the stability and reliability of the equipment, affecting the precision and accuracy of the test. Existing equipment lacks a dedicated waste removal mechanism, requiring the removal of multiple upper components, which remains to be improved. Utility Model Content
