| Abstract:This paper analyzed the mechanical structure of an improved paper reeler and hydraulic pressing process. The mathematical model was established in order to use PLC controlling paper roll with constant linear pressure in the reeling process. Angle values were measured by angular displacement sensors which were installed on the rotating positions of primary arm and secondary arm, respectively. Then the angle value signals were input to the PLC and processed based on the mathematical model, the control signals were sent to the proportional valves. The support cylinder pressure value and the pressure value of the chamber with rod in secondary arm cylinder were controlled accordingly. This method made the paper reel pressure constant therefore to ensure the paper quality without wrinkling. |
