Rewinding Machine Structure - Longitudinal Section
In the mechanical system of the winder, the slitting mechanism is a very important part of the winder. In order to ensure a straight and smooth cutting edge, the quality control of the finished paper roll plays an important role in ensuring the volume. It is easy and can reduce the fluffing during printing.
The slitting mechanism should be installed as close as possible to the paper roll so that it can produce a lateral movement more than necessary during the process of cutting the web without curling.

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.

Belt rewinding machine design and working principle ---

8 core filling
The core loading device supplies a paper core between the take-up rolls.
Construction
A fork-like paper core loader is mounted on the paper feed roller. The core loader includes a paper core clip and a centering tray. The core loader is hydraulically operated. The movement of the paper core clamp is operated by compressed air.
working principle 
The core is placed on a tray in the core loader. It is fixed in position by the paper core clamp.
During the rewinding process, the core loader opens and the new core is advanced. When the core loader is full, the paper core clamp will run to grip the paper core. The core loader moves to the position it should wait when the paper feed roller moves. When the paper advance roller reaches the position where the paper roll is ejected, the core loader is lowered to the drop position. The core holder is opened and the core falls into the middle of the roll.
