Problems solved by technology
At present, the domestic cocoon silk production industry still adopts the traditional live chrysalis reeling technology in the selection of live chrysalis: the length, break point, and first break length of the monofilament are measured manually, and the inspector uses the naked eye to observe and record the number of knuckles , the test results are greatly affected by human factors, and the amount of data is large, which requires a lot of manpower and time. It takes more than ten days to get the results for one test, and the efficiency is very low.
The traditional live pupa silk reeling technology is far behind other production technologies in the cocoon silk industry, which seriously restricts the development of the cocoon silk industry

[0049] as attached figure 1 As shown, the measurement beam emitted by the transmitting tube T1 is uniformly processed by the ground glass 1, and then irradiated on the receiving tube T2 of the photoelectric tube through the low-pass filter 2; the transmitting tube T1 emits a photoelectric signal with a wavelength of 700nm, and the optical signal After the beam passes through the ground glass, it will become uniform under the action of the ground glass; the low-pass wave plate with a cut-off wavelength of 850nm can effectively reduce the interference of various clutter, and improve the anti-interference performance of the optical path detection.
[0050] as attached figure 2 And attached image 3 As shown, the realization principle of the optical path detection of this system is to use the parallel characteristic of light transmission, and the method of casting shadows when there is an object on the light transmission path. When the emitted light is directly irradiated to th...

The invention relates to a method and a device for detecting the quality of a monofilament. The method is characterized by comprising the following steps of: in a region with an equatorial projection area being d1*h on a photoelectricity receiving tube T2, setting a projection diameter d3 of the monofilament passing through the projection region, and a projection diameter d2 of a rough spot passing through the projection region, wherein d2 is greater than d3; setting wire winding comparison voltage V1 and rough spot comparison voltage V2; when a final output voltage V obtained after the output voltage of the photoelectricity receiving tube T2 is amplified through an analog circuit meets the requirement that V is greater than or equal to V1 but is less than V2, recognizing to be normal wire winding; when the output voltage V is greater than or equal to V2, recognizing to be rough spot existence; when the output voltage V is less than V1, recognizing to be filament break or fiber drawing completion; setting a singlechip microcomputer for carrying out data acquisition and control on a signal output by the photoelectricity receiving tube T2; and recognizing normal wire winding, rough spot, filament break or fiber drawing completion of the collected output voltage V of the photoelectricity receiving tube T2 through the singlechip microcomputer. The method and the device for detecting the quality of the monofilament have the advantages that: the quality of the monofilament of silk is automatically detected in filature production, the quality test data can be counted automatically, and the efficiency is high.
Description
technical field [0001] The invention relates to a method for detecting the quality of silk in silk reeling production, in particular to a monofilament quality detection method and a detector for detecting the quality of monofilament. Background technique [0002] In the silk production process, the quality of silkworms is the key factor to determine the quality of silkworms, only good silkworms can spit out good silk. Silk reeling from living chrysalis is to select high-quality living chrysalis as silkworm eggs by comparing the quality of many alternative living chrysalis cocoons, in order to reproduce high-quality offspring and obtain high-quality silk. At present, the domestic cocoon silk production industry still adopts the traditional live chrysalis reeling technology in the selection of live chrysalis: the length, break point, and first break length of the monofilament are measured manually, and the inspector uses the naked eye to observe and record the number of knuckl...
