Automatic detector of cleanliness of fibers and detection method thereof

Abstract

The invention discloses an automatic detector of the cleanliness of fibers and a detection method thereof. The automatic detector comprises a liquid storage box, a testing pipe, an LED light source, an illumination sensor and a liquid level sensor, wherein the liquid storage box is internally provided with a liquid level switch; the lower part of the liquid storage box is provided with a liquid inlet pipe connected with the testing pipe; the side surface of the liquid storage box is provided with a liquid overflow port, and the other side of the liquid storage box is connected with a cleaningelectromagnetic valve; the bottom end of the testing pipe is provided with the LED light source and a concave lens; the bottom of the testing pipe is connected with the liquid level sensor; the top end of the testing pipe is provided with the illumination sensor; the side surface of the upper part of the testing pipe is provided with a ventilation opening connected with the liquid overflow port; one side of the bottom of the testing pipe is connected with a liquid inlet electromagnetic valve, and the other side of the bottom of the testing pipe is connected with a liquid discharge electromagnetic valve; and one side of the testing pipe is parallelly provided with a calibration pipe. The invention adopts a vertical light path measuring method and has high measurement automation degree and accuracy; in addition, the influence of human factors and environmental factors on a measuring result is avoided, thereby a measuring result is objective and accurate.

Description

technical field [0001] The invention relates to a fiber cleanliness detection device, in particular to an automatic fiber cleanliness detector and a detection method thereof. Background technique [0002] Cleanliness test is an important technical index in fiber inspection of down, cashmere, wadding, etc. It shows the content of impurities, dust and free organic matter remaining in the fiber. Fiber and its products with poor cleanliness can cause allergic reactions, asthma and other diseases, and cause serious harm to human health. Accurate detection of fiber cleanliness plays an important role in controlling the quality of fibers and their products. [0003] At present, the cleanliness test of washed down in domestic and foreign standards is mainly based on the transparency meter method, such as GB / T 17685-2003 "Down and Feather", FZ / T81002-2002 "Washed Down and Feather", EN12935: 2001 "Down and Feather Hygiene and Cleaning This method uses a transparency meter to measure...
