Description

Technical Field

[0001] The utility model belongs to the technical field of textile machinery and relates to a hairiness detection device for industrial yarns. Background Art

[0002] In the continuous high-speed production process of industrial yarns, hairiness detection plays a vital role in quality control. Hairiness refers to the fibers protruding from the surface of the yarn bundle. Its presence not only affects the appearance quality of the yarn bundle, but may also have an adverse effect on subsequent processing and performance. Therefore, accurate and efficient detection of hairiness is the key to ensuring product quality and stable operation of the production line.

[0003] In order to achieve accurate detection of hairiness, the industry is constantly seeking technological innovations and solutions. Among them, patent application CN205188527U provides an industrial raw silk hairiness detection device, which uses a signal acquisition module composed of an infrared transmitter and a receiver to accurately record the length, generation time and number of hairs. The application of this technology has greatly improved the automation level and accuracy of hairiness detection, providing strong technical support for industrial yarn production.

[0004] However, the above patents still face certain challenges in practical applications. Especially in the high-speed spinning process, the production oil attached to the yarn bundle will form oil mist, and impurities such as broken short fiber flying will adhere to the lens of the detection device. These pollutants will gradually accumulate on the surface of the lens, affecting the transmittance of light and the quality of signal reception, thereby causing the detection device to generate false signals; specifically, when oil mist and short fiber flying accumulate on the lens, the detection device may mistakenly judge hairless yarn as hairy yarn, and this misjudgment will greatly affect the production efficiency of the production line. In order to ensure the accuracy of the test results, it is often necessary to manually wipe and clean the lens of the detection device at regular intervals to avoid the generation of false signals. However, there are about several hundred lenses used for hairiness detection in industrial yarn production, and usually each lens must be cleaned once within 2 hours. Such cleaning operations are not only frequent, but also huge in workload, which is time-consuming and laborious.

[0005] Therefore, it is urgent to develop a new type of hairiness detection device to solve the problems existing in the above-mentioned hairiness detection process. Utility Model Content

[0006] The utility model aims to solve the problems existing in the prior art and provide a hairiness detection device for industrial yarns.

[0013] The electromagnetic valve is electrically connected to the control system;

[0015] For a hairiness detection device for industrial yarns as described above, the blowing device further comprises a mounting plate, and the mounting plate is fixedly connected to both the hairiness detector main body and the air collecting box at the same time.
