Maintenance of the winder
1. The transmission of the toilet paper rewinder, such as the gear chain, needs to be added with butter.
2. The rewinding machine generally does not have problems. The consumable parts are nothing more than small pinions. If one is added, the printing knife is easy to break. The wool roller will become thinner after one and a half years of loading, and it needs to be transported back to the factory for renovation. If the embossing pattern needs to be replaced in the steel roll embossing device, it is necessary to transport the steel roll back to the original factory for modification, and it will not cost much.
3. Pay attention to the voltage of the winder should be stable, otherwise it is easy to burn the motor; pay attention to hygiene, do not let the debris fall between the steel roller and the roller.

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

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.

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"
