Small raw silk fineness inspection device for silk reeling enterprises

Abstract

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.

Description

technical field [0001] The invention relates to the field of raw silk quality inspection, in particular to a small raw silk fineness inspection device for silk reeling enterprises. Background technique [0002] Raw silk fineness refers to the thickness of raw silk. The current standard GB / T1798-2008 "Raw Silk Test Method" is used to test the raw silk fineness. The detection method is as follows. 50 spinning spindles (2 spinning spindles for each skein sample), take up the fineness yarn with a fineness machine, and take up 4 strands for each spinning spindle, 100 twists per twist, a total of 200 strands, and then use the fineness meter to weigh the fineness of each strand . [0003] The fineness detection of raw silk evaluates the thickness and uniformity of raw silk through indicators such as average fineness, fineness deviation, and maximum fineness deviation. Uneven thickness of raw silk means that the quality of raw silk is poor, which is not conducive to the subsequent ...

AI Technical Summary

Problems solved by technology

This kind of inspection device for indirect measurement of raw silk fineness uses physical methods to brake. The obtained raw silk length has a high error, the device takes up a lot of space, and the size of the winding mechanism is stipulated by the national raw silk inspection standard, which is not suitable for the raw silk fineness inspection requirements of silk reeling enterprises.
