Rewinding Machine common fault - Governor does not display
1, the power is not connected - connect the power
2, open is not open - dial open
3. The speed regulator and inverter connection cable are disconnected or damaged - check the network cable
4. The power on button is damaged - replace the button
5, governor failure - contact the manufacturer
Guolian High Speed ??Slitting Rewinder Technical Description ---
Second, the system configuration
1. Main transmission part: 1 set of paper-removing brake generator, 400kW (YVP4501-6 or
1LA8357-6), one roller motor (YVP225S-4), 37kW, two pressure roller motors (YVP132S-4), 5.5kW, two coiling motors (YVP355L2-4) (one for each front and rear roller) , 315kW, 6 paper cutter motor, 0.55kW, total installed capacity 1082kw (model and power are subject to final design). The rectification feedback and the inverter unit and the tension controller matched with the above constitute a transmission control system.
2. Logic control part: PLC host 1 block.
3. The logic control system selects the S7-400 series products of SIEMENS.
4. Tension control part: 1 set of tension detection and control system, using Sweden
5. 1 set of coiling roller pressure detection and control system.
6. The diameter detecting sensor of the take-up roller.
7, with position detection, pressure detection, liquid level detection, safety detection sensor and phase
The control agency should be controlled.
8. On-site operation panel, logic control panel, and electric drive panel.
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"
