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.

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.
