Embodiment Construction

[0019] The present invention will be further described below in conjunction with specific examples, but the scope of protection required by the present invention is not limited to the scope described in the specific examples.

[0020] According to attached figure 1 A yarn detection device is used to make a certain width yarn 3 pass through the imaging area 5, and the yarn is driven by the yarn delivery device 6. Under the action of the tension constant device 4, the yarn 3 is kept in a constant and repeatable tension state and enters the imaging area 5 to complete the imaging.

[0021] The illuminant 2 provides enough light in the imaging area 5 so that the image passes through the focusing lens 7 to the image sensor 8 to achieve clear imaging expectations. The illuminant control device 1 controls the light of the illuminant 2 by means of output level control. The illuminant 2 can be an adjustable incandescent lamp. This provides a variable intensity yet steady light. In t...

Abstract

According to a yarn testing device, an image sensor can perform dimension testing and color testing simultaneously. The image sensor receives yarn information; and pixels are input into an electronic controller through voltage by means of pixel representation. In receiving an image, pixels are converted to voltages, thereby realizing dimension testing and color testing successively. The yarn testing device has advantages of ensuring practicability and precision of final hairiness data, greatly improving efficiency and reducing testing cost.

Description

technical field [0001] The invention relates to a yarn detection device, in particular to a detection device and detection method for measuring yarn hairiness. Background technique [0002] Yarn hairiness is one of the signs to measure the quality of yarn. Hairiness affects the uniform dryness and smooth surface of the yarn, affects the strength utilization coefficient of the fiber, reduces the strength of the yarn, and makes the wear resistance of the yarn worse. Yarn hairiness is an important factor affecting the appearance, feel and performance of the final product. With the improvement of people's requirements on the performance of textiles and the special requirements of new high-speed looms on the smooth surface of yarns, the problem of hairiness has attracted more and more attention from manufacturers and users. In this case, it is very important to test the yarn hairiness, not only to check the quality of the yarn, but also to guide the production. Therefore, it is...
