Rewinding Machine operating procedures - Rewinding
Firstly, the switch is automatically turned on, and then the paper is positioned to automatically unload the paper. After the unloading is completed, the main operation uses the box rule to measure the size of the rolled paper and observe the trimming of the end face and the rewinding of each end roll. Whether the end face has a burr.

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

4.1 Research significance
The significance of this paper is to apply advanced field bus and frequency conversion technology to the traditional paper industry, making the rewinder control system very practical and advanced for a long time.
Firstly, the new Profibus field bus is used to replace the system's large number of I/O wiring, which effectively avoids the interference of the signal; the OP operation panel is used to replace the analog secondary instrument and switch button of the original system. The control system is divided into two levels: the monitoring machine (operator panel) and the field control level (lower position machine). Through the system, the operator can timely understand the various operating states of the winder through the OP panel, analyze the cause of the fault, and make corresponding adjustments and controls on the OP panel according to the site conditions in time. The new control system adopts the frequency conversion control technology, which abandons the DC rotation control mode of the original system of the winder. The application of the frequency conversion technology improves the speed and control precision of the system. The modified vehicle speed reaches 1200m/min (line speed), which is the original system. Twice, at the highest speed, the speed error does not exceed 2%. The friendly man-machine interface system can effectively control the entire production process of the winder, realize effective control of key production parameters, ensure safe and stable production, improve economic efficiency, and reduce labor intensity of workers.
Secondly, the implementation scheme of the new control system has strong universality. The software and hardware design and transformation of the general data acquisition system can connect the original system to the field bus, and the design of the tension and load distribution control of the winder The equipment transformation in the paper industry and the cigarette industry has certain reference significance.

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.
