Rewinding Machine safety operation guide - 

Third, the rewinding machine opening and closing operation sequence:

2. When the paper roll reaches the specified rewinding diameter (meters), the working speed will slowly drop.
After the paper roll reaches the specified diameter (meters), press the “stop” switch. After the quality inspector has measured the paper roll and the appearance quality, tape the outermost piece of paper with a tape and stick the paper. The inner core of the core barrel is pulled out (the thimble) and the bottom knife roll is lifted to remove the paper roll.
3, the rewinding machine should have a long downtime, stop the paper side fan, and do a good job of surrounding sanitation.

Automatic rewinding machine speed ratio adjustment method ---

3. Adjust the curved shaft behind the punching knife. The curved shaft is finally stretched as a smooth transition axis before the web is wound up. The position of the position and the working arc size not only affect the smoothness of the paper web, but also affect the stability of the web transport. When the curved axis is too high, the paper web is scratched by the punching surface knife, and the jitter is large and the paper is easy to break. When the position is too low, the paper web is scraped to the low hole and the broken layer is easy to break. Generally, the height of the curved shaft position is adjusted so that when the paper web passes through the punching knife, the bottom layer is preferably 5~8 mm higher than the punching bottom knife, and the working arc of the curved shaft is as small as possible, and the paper can not wrinkle.

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"
