Rewinding Machine common fault - The platen roller does not move
1. Proportional valve is unstable. - Clean the proportional valve or replace the proportional valve to adjust the amplification signal.
2. Control failure - on-site debugging of the instrument.
Guolian High Speed ??Slitting Rewinder Technical Description ---
Fourth, performance guarantee

3, the seller guarantees that the rotating components will not affect the running performance, paper quality, equipment can
Responsive or maintenance vibration.
4. The vibration guarantee is valid only when the basis of the winder is designed according to the requirements of the seller. 5. Mechanical guarantees do not include natural wear and consumables and consumables.
6. Selling due to improper storage, transportation, installation, maintenance and operation by the buyer
The party is not responsible. The buyer’s modification of the equipment is not guaranteed by the seller.
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"
