Abstract

The invention relates to a mooney viscometer. The mooney viscometer comprises a lifting cylinder, which is mounted at the upper end of a machine frame, wherein a piston rod of the lifting cylinder is connected with an upper mold in the machine frame; a lower mold frame is arranged at the lower end of the machine frame; a lower mold corresponding to the upper mold is arranged at the upper end of the lower mold frame; a rotor is arranged in an inner hole of the lower mold; the rotor is sleeved with a spindle; the spindle is mounted in a bearing seat at the upper end of the lower mold frame via a bearing; a driving gear is arranged at the lower end of the spindle and located in the lower mold frame; a motor is arranged in the lower mold frame; the output end of the motor is connected with the driving gear; a cylinder is arranged at the lower end of the spindle and mounted on the lower mold frame; the piston rod of the cylinder is in contact with the lower end of the rotor; a sealing ring is arranged between the rotor and the lower mold body; the inner hole of the sealing ring is tapered. The mooney viscometer is simple in structure, and the sealing ring with the tapered inner hole is additionally arranged between the rotor and the lower mold, as a result, fused rubber can be effectively prevented from entering a gap between the rotor and the lower mold, and the fractional resistance of the rotor against the sealing ring is reduced.

Description

technical field [0001] The invention relates to a rubber Mooney viscosity testing device, in particular to a Mooney viscosity meter. Background technique [0002] The application of rubber is very extensive. In order to obtain high-performance rubber products, the characteristic changes during rubber processing and the characteristics after processing should be tested and analyzed to obtain the best formula and processing parameters. The existing main test The analytical equipment includes a Mooney viscometer and a vulcanization meter. [0003] Mooney viscometer is an index to measure the average molecular weight and plasticity of rubber. The Mooney viscosity is measured with a Mooney viscometer. The Mooney viscometer is a standard rotor. The shear resistance on the rotation of the rotor is related to the viscosity change during the vulcanization process of the sample. The unit is displayed. The rotor of the existing Mooney viscometer will form a gap with the lower mold w...
