In the production line of spunlaced nonwovens, it is very important to accurately control the tension of each link.
Firstly, in the fiber opening and mixing stage, the tension state of the fiber is monitored in real time by installing a high-precision tension sensor. According to the feedback data, the automatic control system is used to adjust the running speed or conveying strength of the equipment to achieve the appropriate tension level.
In the carding process, the design and parameter setting of carding machine are optimized to ensure the uniform and stable tension of fiber during carding. Advanced tension adjusting device, such as adjustable roller or tension compensation mechanism, can be used to make fine adjustment according to the actual situation.
In the process of spunlace, the tension should be indirectly affected by the control of water pressure and water quantity. Reasonable adjustment of the position and angle of spunlace head can not only achieve good entanglement effect, but also avoid excessive tension fluctuation. At the same time, in the process of conveying fibers to the spunlaced area, accurate guide rollers and tensioning devices are used to maintain the constant tension.
In the drying and winding stages, the precise transmission system and tension control system work together. According to the characteristics and process requirements of non-woven fabrics, the appropriate tension value is set, and the tension is always within the precise control range through continuous monitoring and adjustment.
In addition, it is essential to establish a perfect monitoring system and data analysis mechanism. Record and analyze the tension data of each link in real time, find the abnormality in time and take corresponding measures. Maintain and calibrate the equipment regularly to ensure the accuracy and reliability of the tension control device.
Through the comprehensive application of the above measures, combined with advanced technology and strict management, the tension of each link in the spunlaced nonwovens production line can be effectively controlled accurately, thus ensuring the product quality and smooth production.
