Embodiment Construction

[0016] Reference attached figure 1 , 2 , 3 describes an embodiment of the present invention.

[0017] An automatic detection method for neps and impurities in cotton sliver:

[0018] ① Draft the sliver to form a cotton net with uniform width and uniform thickness;

[0019] ② Irradiate the cotton net evenly with light;

[0020] ③Using an area-scan CCD camera to capture images of the cotton net on the black and white backgrounds;

[0021] ④ Apply image processing technology to pre-process the image signal captured by the area array CCD camera;

[0022] ⑤The pre-processed image signal is sent to the computer, and the neps and impurities on the cotton web are classified and counted through the computer to output the data.

[0023] An automatic detection device for neps and impurities in cotton sliver, in which a sliver drafting mechanism (2), a black and white bottom plate (3), a cotton web drafting mechanism (4) and a cotton web are vertically arranged in the shell (1) The collectio...

Abstract

The present invention is automatic detection method and apparatus for cotton neps and impurity in silver. The detection apparatus has in the casing a silver stretching mechanism, a white-and-black bottom plate, a web stretching mechanism and a web collecting box. The white-and-black bottom plate locates between the silver stretching mechanism and the web stretching mechanism, and in front of the white-and-black bottom plate, there are area CCD camera and light source. The present invention can detect automatically cotton neps and impurity in silver in high efficiency, and the detection result may be used in evaluate cotton carding apparatus. Improving the cotton carding apparatus can raise the quality of yarn and fabric.

Description

Technical field [0001] The invention relates to an automatic detection method and device for neps and impurities in cotton sliver. Background technique [0002] At present, domestic textile companies use manual testing to detect the size and quantity of neps and impurities in cotton slivers. That is, after the sliver is drawn into a cotton net by the manual drafting mechanism, the number of neps is counted with naked eyes under the black bottom plate, and the number of impurities is counted with naked eyes under the white bottom plate. At least two workers are required to perform inspections every day. The labor intensity is high and fatigue is easy. The statistical results of inspections are greatly affected by human factors. Summary of the invention [0003] The technical problem solved by the present invention is to design an automatic detection method and device for neps and impurities in the sliver, a device for automatically drafting the sliver into a cotton web, and an im...
