Yarn Tension Control For Lawn Tufting Machines

Yarn tension control system is an important link in the textile industry. The quality of tension control directly affects product quality and production efficiency. Especially in the process of carpet tufting, the yarn tension affects the amount of yarn fed, thus affecting the quality of the carpet surface.

Because many factors affect the yarn tension during carpet tufting, and the yarn tension is small and easily disturbed, yarn tension control has always been a difficult problem in the textile industry. And most of the tension control devices on the market are mainly mechanical, and there are few electronic control devices.

When testing the tension, because the yarn is constantly moving, it is difficult to directly collect the yarn tension, and it cannot be measured directly by simply using a tension sensor. In order not to affect the original tension of the yarn, a roller is set in the direction of the yarn movement, which consists of a collection wheel and two fixed rollers, and the yarn tension is indirectly converted into the pressure on the collection wheel. The measurement of yarn tension can be obtained by calculation. The yarn to be tested is wound so that the yarn forms a fixed angle between the fixed roller, the collecting wheel and the fixed roller, and the sensor is fixed on the collecting wheel.
