Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] The main invention contents of the present invention include

[0021] 1. Set up a set of cotton sample net making device to make cotton into a uniform cotton net with a thickness of about 1mm;

[0022] 2. Set up a set of image acquisition system to collect images of the cotton web passing through the image acquisition area;

[0023] 3. Through the "identification and measurement software" installed in the computer, the foreign fibers in the collected images are identified and classified, and the area of ​​the foreign fibers is calculated;

[0024] 4. According to the mathematical model of the relationship between the area and weight of foreign fibers, the results of image recognition and classification are calculated, and then the weight of foreign fibers in cotton is obtained.

[0025] Such as figure 1 Shown, the cotton sample net making de...

Abstract

The present invention relates to a cotton isomerism fiber detecting and measuring device, and a detecting and measuring method thereof. The device is characterized by comprising a cotton sample network preparing device, a cotton network collecting device, a detection box and a computer; the forefront of the cotton sample network preparing device is provided with a pair of cotton transmitting rollers and a pair of drawing rollers; one of the cotton transmitting rollers and the drawing rollers is provided with an encoder which is used for recording the transmission velocity and the position of the cotton network; the detection box is positioned between the two cotton transmitting rollers and the two drawing rollers; a detection channel is positioned in the detection box and is a transparent rectangular tube; one side or two sides of the detection channel are provided with a set of image acquisition systems; the computer is respectively connected with the signal acquisition card of the encoder and the image acquisition cards of the image acquisition systems; a set of isomerism fiber image identifying and measuring software is arranged in the computer; and the computer is connected with a displaying and printing device. The device and the method can be widely used in cotton quality inspection departments, cotton processing enterprise and cotton spinning enterprises.

Description

technical field [0001] The invention relates to a detection and measurement device and a detection and measurement method, in particular to a detection and measurement device and a detection and measurement method capable of finely identifying and accurately measuring foreign fibers in cotton. Background technique [0002] Foreign fibers in cotton mainly refer to non-cotton fiber materials such as woven bag silk (polypropylene yarn), colored thread, human and animal hair, chemical fiber silk, plastic film, cloth strips, poultry feathers, hemp rope, etc. Most of them are in cotton picking and circulation. produced in the segment. Over the years, due to the existence of foreign fibers, the quality of cotton yarn and cotton cloth has been seriously affected. In the process of spinning and weaving, foreign fibers will not only reduce the spinning efficiency and form gauze defects, but also affect the color and appearance quality, seriously weakening the domestic market. The comp...
