Description

The present invention relates to a servo tensioner technical field and relates to a servo tensioner without a spring tension rod.

The birth of the Servo Tensioner is a historic reform based on traditional tension technology. Servo tensioners feature active wire feed, have advantages such as high control accuracy, sensitive response, constant tension, etc., and provide technical solutions to the high-end coil manufacturing field to solve them. With rapid economic development and rising material living standards, the growing demand for companies to produce sophisticated product quality urgently requires process technology reforms to ensure improved quality and efficiency. It promotes continuous progress and improvement of servo tensioner technology.

Existing servo tensioners need to combine a servo drive system with a mechanical structure assembled with a spring tension rod as the main component. In the mechanism, the spring tension rod is the main part where tension is generated and it is necessary to select or replace different spring tension rod specifications for different tension demands. Such a design has the problem that there are many spring tension rod specifications, which causes inconvenience in switching between different tension ranges. Switching between different tension ranges requires frequent man-made spring tension rod replacement, resulting in increased manual operation and the use of standardized processes. In addition, there is a very high possibility that failures such as spring deformation and breakage will occur due to improper use or improper model specifications. Further, in the servo tensioner of the spring tension rod structure, the corresponding tension is generated by the relative tension between the spring and the tension rod. Such a structural principle has a limit on the parameters of the range that outputs tension, and when a large parameter is required for tension output, it is necessary to increase the spring tension rod, and if the spring tension is increased infinitely, In addition to serious strength problems throughout the structure, the infinite increase in spring tension rods reduces tension stability and buffer sensitivity.
