Fiber Cleanliness Automatic Tester Is Identified.

Recently, experts from the Sichuan Provincial Bureau of quality and technology supervision carried out the appraisal of the results of the development of the automatic testing instrument for fiber cleanliness, which was led by the Sichuan Fiber Inspection Bureau.

According to the introduction, the instrument developed by this project has been realized. Instrumented The detection method instead of the traditional manual detection method provides new technology and equipment for the accurate and objective detection data.

It is reported that the project is based on Lambert-Beer Law Find out. fibre The relationship between cleanliness and the concentration, transmittance, absorbance and turbidity of the extract is formulated. The calibration method and calibration method for the automatic detection of fiber cleanliness are formulated. The vertical optical path is innovatively designed, and a new type of fiber cleanliness automatic detector is developed, and one of the utility model patents and one invention patent is obtained, with independent intellectual property rights.

Introduction: CMT1800 roving and intelligent full-automatic roving frame system is an important part of realizing the unmanned spinning plant. The spinning factory can realize the digitalization, intellectualization and continuity of production, and then develop into an unmanned chemical plant.

Scientific and technological innovations: (1) the combination of the automatic doffing system and the coarse and fine joint system. Through fieldbus technology and modern control technology, the whole process from spinning to automatic doffing, full yarn and ATC automatic transportation, bobbin on-line monitoring and processing of logistics and information flow has been realized.

(2) a plurality of roving frames can share an intelligent yarn library, and multiple yarn libraries can be invoked each other. The intelligent yarn library has multiple varieties identification system, which solves the problem of different roving varieties confusion and multi variety production problems.

(3) the intelligent yarn library adopts the first in first out principle, so that roving and ATC can be stored in the yarn store for the shortest time, ensuring the quality of roving.

(4) the automatic cleaning and monitoring function of the air tube tail yarn. Through the on-line cleaning of the tail yarn cleaning machine and the loosening of the sliver, the monitoring device detects unqualified bobbins and automatically changes the qualified bobbins.

(5) with the color recognition function of the bobbin, the roving of each species can be allocated to the color of a bobbin, and the color of the bobbin can be detected by the color sensor to determine the variety. Radio frequency identification technology can also be used for variety identification and validation, so as to achieve product quality traceability. '

(6) roving frame four frequency conversion synchronous control and doffer device three variable frequency synchronization, ensure the automatic control of the spinning doffing process, so that the doffing time is less than 120 seconds.

(7) multiple yarn library collective network control is realized, and the supply and demand situation of monitoring roving is realized by using PLC, fieldbus technology and networking communication system. Using Internet technology to realize the full integration of logistics and information flow between processes, it is possible to effectively match any roving frame and spinning frame within the system.

(8) production management adopts the embedded software developed independently, which can collect and analyze the whole production process. The Internet technology such as radio frequency identification and radio frequency identification can realize output statistics, quality tracing, data analysis and production dynamic query. It can also share resources with the ERP lamp management software of the client.
