Tension information detection method

(1) Tension sensor detection method: It is a method of detecting the tension directly, closely combined with the machine, and without moving parts. Usually two sensors are paired and mounted on the end shafts on both sides of the detection guide roller.
(2) Roll diameter calculation type detection method: It uses the proximity switch installed at the reel to detect the rotation speed of the reel. Because the reel rotates once, the winding diameter will change twice the thickness of the material.The current diameter of the reel is obtained by cumulative calculation by the initial value of the reel diameter and the material thickness, and the change of the corresponding reel diameter reflects the change of the actual tension value.
(3) Floating roller position detection mode: It uses the cylinder attached to the slitter to connect the floating roller to drive the angular displacement sensor to detect the tension change. When the tension is stable, the tension on the material is balanced with the cylinder force, so that the floating roller is in the center position. When the tension changes, the balance between the tension and the cylinder force is broken, and the position of the floating roller will rise or fall. At this time, the swing lever will rotate around a point and drive the floating roller angular displacement sensor to rotate together.
(4) Floating roller position + tension sensor combined tension detection mode: It can simultaneously detect the floating roller position signal output by the floating roller angular displacement sensor and the tension signal output by the tension sensor, thereby providing higher precision tension control to the system.
