PHOTOELECTRIC AUTOMATIC TESTER FOR CHECKING UP THE HOMOGENEITY AND DEFECTS OF SILK

The utility model discloses a photoelectric automatic tester for checking up the homogeneity and defects of silk, an optical imaging system is arranged, and on the photo surface of the photoelectric automatic tester, a rectangular optical grating is arranged. A photoelectric detector on the rear of the photoelectric automatic tester outputs the electric signal proportional to the silk diameter of the silk and goes through a signal pretreatment circuit, then the signal is processed by a computer, and last the photoelectric automatic tester automatically gives out the quantitative test index of the homogeneity and the defects by a printer. The utility model which has the advantages of simple structure, convenient operation and high reliability can replace the traditional test equipment of the blackboard and simplify the test technology. The photoelectric automatic tester is suitable not only for checking up the silk but also for checking up the homogeneity and defects of other textile fibers.
