When the marking mechanism works, the ejection mechanism 6 performs one-time telescopic action to eject the spun yarn 9 onto the collodion inkpad 7, so that an operator can conveniently identify the specific position of the unqualified and fine spun yarn.

The spinning broken yarn detection equipment and the spinning machine are electrically connected with an external control system.

The embodiment also provides a broken yarn detection method of the textile broken yarn detection device, which comprises the following steps:

s1: detecting the tension of the spun yarn 9 by the tension detection mechanism 8, when the tension of the spun yarn 9 is smaller than a preset value, adjusting the tension of the tension detection mechanism 8 by rotating a rotating bolt 82 on the tension detection mechanism 8, outputting an electric signal by a down-bouncing extrusion pressure sensor 86 by a longitudinal sliding plate 84 in the tension detection mechanism 8 when the tension of the spun yarn 9 is lost, controlling an early warning module 10 by an external control system to give an early warning prompt, stopping the operation of the textile machine at the same time, or executing S2;

s2: measuring the electric signals output by the photoelectric element 5 under different light intensities, and manufacturing a standard bus; that is, the photoelectric element 5 converts an optical signal into an electrical signal and outputs the electrical signal, and the electrical signal is increased with the increase of the light, and the optical signal and the electrical signal have a certain relationship with each other, and a reference bus line as a relationship line between the optical signal and the electrical signal is formed.

S3: measuring electric signals output by the photoelectric element 5 under different light receiving areas under various illumination intensities, and respectively manufacturing standard buses; under the same illumination intensity and different light receiving areas, the electric signal output by the photoelectric element 5 also changes, and standard buses for outputting the electric signal under different light receiving areas and different illumination intensities are manufactured. The specific steps are to measure the light intensity of the light source 2 when emitting light normally, for example, the normal light intensity of the light source 2 is 50lx, and to measure the electric signals output by different light receiving areas under each illumination intensity of 0-50lx, that is, the electric signals output by the photoelectric elements 5 with different light receiving areas under 50lx light intensity, the electric signals output by the photoelectric elements 5 with different light receiving areas under 49.9lx light intensity, the electric signals output by the photoelectric elements 5 with different light receiving areas under 49.8lx light intensity, and so on.

S4: by taking the electrical signal received by the photoelectric element 5 in the independent cavity without the through hole 11 below the transverse partition plate 3 as a reference, the illumination intensity of the light emitted by the light source 2 through the light-transmitting opening 31 is obtained according to the measured reference bus;

s5: selecting standard buses corresponding to the output electric signals of the photoelectric elements 5 with different light receiving areas under the illumination intensity by taking the obtained illumination intensity as a reference;

s6: at the same time, the light receiving area of the electro-optical element 5 at the spinning 9 side at the time is obtained according to the electrical signal output by the electro-optical element 5 at the spinning 9 side and the standard bus selected in S5.

Since the existence of the spun yarn 9 blocks the optical fiber, the light receiving area of the photoelectric element 5 changes.

S7: subtracting the light receiving area measured in S6 from the light receiving area of the photoelectric element 5 on the spinning 9 side without shielding to obtain the shielding area of the shadow formed by the spinning 9;

s8: the shielding area of the shadow formed by the spinning 9 is compared with a preset threshold value, when the shielding area is smaller than the preset threshold value, the ejection mechanism 6 performs one-time telescopic action to eject the spinning 9 to the collodion inkpad 7, red marks are left at two ends of the spinning 9, the thin but unbroken part of the spinning is marked, the spinning machine stops running, and meanwhile the early warning module 10 performs early warning prompt.

The threshold value is an empirical value, that is, when the shadow area (shadow area is corresponding to the thickness of the spun yarn 9) cast by the spun yarn 9 is smaller than the threshold value, the warning prompt is performed.

The method can not only realize early warning when the spinning is broken, but also realize early warning notification when the spinning is thin but not broken, and the staff can process the thin part in advance, thereby ensuring the quality of the product.

In addition, in the method, the photoelectric element 5 on the side without the through hole 11 is used as a reference for measurement, so that the situation of false measurement and false alarm caused by the fact that the output electric signal of the photoelectric element 5 is reduced after the light intensity of the light source irradiation is changed can be effectively avoided.

Further, when the shielding area for forming the shadow of the spun yarn 9 in the S8 is smaller than the preset threshold value, the external textile machine further conveys the spun yarn 9 forward for a distance of 2L-3L, and then stops running, wherein L is the length of the shell 1; the arrangement can lead the marking section of the inkpad of the spinning 9 to penetrate out of the shell 1, thereby being convenient for the staff to process the thinner section of the spinning.
