Automatic rewinding machine speed ratio adjustment method ---


        The rewinding machine is the first station of the production line equipment of the welcoming machine. The good running condition of the rewinding machine directly affects the quality and production efficiency of the post-processing welcoming paper. The rewinding machine should be able to operate normally and in a good production state. In addition to the good and non-damage of the components, the reasonable adjustment and control of the transmission ratio of the whole machine is very important.
        When the rewinding machine is produced, the original paper web is conveyed by five transmission rollers and belts, that is, a paper feeding belt, a curved roller, a rear platen roller, a front platen roller, a winding roller, and the like. Each of the base papers is thin, the elongation is limited, and the transmission speed ratio is unstable, and the paper web is easy to wrinkle and be broken during the continuous acceleration and deceleration operation of the winder. Reasonable adjustment and control of the speed of each drive roller and paper feed belt can greatly reduce the phenomenon that the paper web is broken. After many daily adjustments, the author summarizes the following key adjustment methods. 1. Stable paper feed belt conveys the line speed of the original paper web. The paper feeding belt of the rewinding machine is driven by the V-belt through the stepless speed-regulating wheel. When the output torque is large, the driving V-belt is close to the outer edge of the speed-regulating wheel, and the transmission speed will be more stable. In order to achieve such a stable transmission effect, the speed ratio of the main gearbox can be adjusted step by step to make the speed of the winding roller slower, and at the same time adjust the speed control handwheels of the paper feed belt of the original paper frame, so that the three sets of transmission triangle belts are in The outer edge of the stepless speed regulation wheel is in a reasonable position until the winding speed of the winding roller and the paper feeding belt are the same.

Design and application of constant tension and load distribution control for winder---

2. Main research content
(1) On the basis of understanding the working principle and production process of the rewinder, determine the AC drive configuration scheme of the rewinder and the common DC bus power supply mode.
(2) In view of the influence of the change of the winding diameter on the tension during the rewinding process and the phenomenon of paper break and loose paper during acceleration and deceleration, a composite tension control method combining direct tension and indirect tension is proposed, and the real-time calculation and dynamics of the winding diameter are designed. Torque compensation program that effectively corrects tension disturbances to ensure constant tension during rewinding
(3) Software and hardware design to complete the pressure control of the platen roller”

(4) After detailed analysis of the causes of the load distribution of the bottom roller motor before and after the detailed analysis, determine the master-slave control scheme of the two motors, design the load distribution control system.
(5) Establishing a profibus-Dp network system, designing communication between pLC and inverter! Op operation panel"

(6) Using STEP7 to design the software of the rewinder control system, using ProTool to compile the entire monitoring system screen"
