Guolian High Speed ??Slitting Rewinder Technical Description ---
Third, the function introduction
1. The tension control of the eject roller consists of a tension sensor and an eject motor.
In the loop control loop, the paper take-off motor is an electric motor when unwinding, and is a brake generator during normal operation and parking.
2. The pressure control of the pressure roller is controlled by various sensors such as the take-up roller diameter detecting sensor.
Forming a closed-loop control system, there are three pre-made curves for different paper grades and different finished paper diameters for the operator to choose, and the actuator will be controlled according to these three different pressure curves.
3, between the two take-up bottom rollers, take the torque difference control method, corresponding to no
The same take-up diameter, the torque between the front and rear bottom rollers is distributed in different proportions.
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.
