AUTOMATIC OIL CONTENT MEASURING INSTRUMENT

PURPOSE:To automatically, rapidly and highly accurately measure oil content adhering to synthetic resin by injecting an oil content extracting solvent successively to samples, receiving extracted oil to a successively heating and evaporating the oil component, weighting the residual, and then calculating adhering oil content. CONSTITUTION:A previously weighted fiber sample 6 is successively moved to the lower part of a sample charger 14 by a feeding table 8 and pressed into an oil content extracting cylinder 1 by the charger 14 and the oil extracting solvent is injected into the cylinder 1 by a solvent quantitative injector 15. On the other hand, the receiver 5 is previously weighted by a balance 19, rotated in parallel with the cylinder 1 and moved to the lower part of the cylinder 1, and the solvent is rinsed out from the lower hole of the cylinder 1 and received by the receiver 5. The received solvent is vaporatized by a heater 20, the residual is weighted by a weighting balance 18 and the adhering oil content can be automatically, rapidly and highly accurately measured on the basis of the weight of the receiver and the weight of the fiber.
