Rewinding Machine common fault - Paper roll end faces are not aligned
1. Top core movement - Check the top core plane bearing and lock nut and adjust the clearance.
2. The top core force is not enough - check the air motor.
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.

3 limitations of the original control system
This paper is aimed at the transformation of the rewinder analog DC drive system. The original rewinder control system mainly has the following shortcomings and limitations:
(1) The original rewinder control system is the DC drive control system of Siemens AG of Germany. Due to the DC motor drag, the analog regulator is adjusted, the device parameters are easy to drift, resulting in the reliability and accuracy of the rewinder, and Affect the quality and efficiency of rewinding, the maximum speed is only about 600m/min, it is difficult to meet the production requirements of high-speed paper machines.
(2) The original system uses mechanical buttons and instruments to operate and monitor the production process. The information integration capability is not strong. The process parameters of many production processes cannot be obtained, which increases the labor intensity of workers' operations and the time of manual participation in production, which affects the rewinding. Machine utilization and automation.
(3) The original system is a centralized system. A large number of I/O cables are distributed between the control room and the site, which not only increases the cost but also increases the system's unreliability.
(4) Due to incomplete information of field-level equipment, online fault diagnosis, alarm, and recording functions of field-level equipment are not strong. On the other hand, it is difficult to complete the parameterization functions such as remote parameter setting and modification of field devices, which affects the maintainability of the system.
