The invention relates to a small raw silk
fineness inspection device for silk reeling enterprises. The device comprises a
fixed length silk picking module, a silk guide module, an STM32 single-
chip microcomputer controller, a high precision electronic scale, a silk
ingot, a rack and a computer, wherein the
fixed length silk picking module comprises a winding mechanism, two bearing seats and corresponding bearings, an
alternating current (AC)
servo motor, a
servo driver and a
servo motor support; a transmission shaft of the winding mechanism is fixed by means of a
cantilever beam, a
fixed length raw silk can be wound onto the winding mechanism from the sink
ingot, and a silk picking operation can be performed at the non-fixed side; the silk guide module comprises a
ball screw slide table, asilk guide hook position adjusting device, a silk guide hook, a broken silk detecting sensor and an adjustable bracket; the
ball screw slide table translates the silk guide hook so as to translate the winding position, so that a stacking error is eliminated; the broken silk is detected at the same time. The small raw silk
fineness inspection device is small in overall size, and the length of theraw silk to be detected is flexible to obtain; the demand of small-scale and diversified raw silk
fineness self-testing of the silk reeling enterprises can be met.
