Abstract

The invention discloses an automatic sample injection device suitable for full-automatic viscosity measurement. The device comprises a gas bath temperature control bin and a sample injection bin. A mesh bin partition plate is arranged between the gas bath temperature control bin and the sample injection bin. An automatic sample injection rotary disc is arranged in the sample injection bin and comprises a reagent bottle, a rotary motor, a lifting motor and a sample injection disc. The reagent bottle is arranged on the sample injection disc, the rotary motor controls the sample injection disc to rotate, the lifting motor controls the reagent bottle to ascend and descend, a round hole allowing a sample injection needle to penetrate is formed in the top of the sample injection bin, a PTC heater and a turbulence draught fan are arranged in the gas bath temperature control bin, and the PTC heater is connected with a temperature controller. The accuracy of measured data is guaranteed, labor is saved, working efficiency is greatly improved, and the safety of experimental facilities and staff is guaranteed.

Description

technical field [0001] The invention belongs to the field of polymer experiment instruments, and more specifically relates to an automatic sampling device for full-automatic viscosity measurement. Background technique [0002] In petrochemical, chemical fiber and other polymer fields, the measurement of polymer viscosity or viscosity-average molecular weight is a very important indicator for testing product performance, such as in polyester PET, PBT, nylon PA6, PA66, etc. Polycarbonate PC, polyvinyl chloride PVC, polyacrylonitrile PAN, polyacrylamide PAM, polyvinylidene fluoride PVDF, organic silicon, organic glass PMMA, polylactic acid PLA, PGA, cellulose CA, MCC, and other polymer materials In the field of production and research, according to international or national standards, viscometers are used to measure the viscosity value or viscosity average molecular weight and other results. [0003] At present, domestic viscometers only realize the process of automatic measur...
