Rewinding Machine common fault - Rolls are not collected
1. The original coil is not uniform - Finish the original coil to ensure that the original coil is neat
2, paper core size head - check the paper core
3, only start a short period of time - normal phenomenon,
4, bearing damage - bearing damage is often accompanied by abnormal noise, pay attention to check the bearing, found that the damage is replaced in time
5, shaft damage - contact the manufacturer
Guolian High Speed ??Slitting Rewinder Technical Description ---
Part II: Hydraulic and pneumatic parts:
1. Hydraulic part:
The local hydraulic system consists of a hydraulic pump station and a valve station. System control and transmission components use world famous brand products. All hydraulic lines of the winder are supplied.
The hydraulic pump station uses three oil pumps to provide pressure oil source. The hydraulic station has safety facilities such as liquid level alarm, temperature control, filter blockage alarm, and a set of circulating filtration and cooling system. The valve station control section includes:
1) Ejection shaft ejection and locking device 2) Ejection frame movement 3) Ejection shaft clutch
4) Hook protection device 5) Paper core plug locking device 6) Press roller load reducing device
7) Unloader unit 8) Push roller unit 9) Stop roller holder lifting device
10) Ejection shaft hydraulic disc brake 11) Guide roller hydraulic disc brake
12) Front and rear bottom roller hydraulic disc brakes 13) Head lifting device.
14) Paper core positioning device 15) Paper head clamping lifting device
16) Automatic paper changer lifting device
The hydraulic circuit has the following features:
A. This system adopts superimposed valve, which is simple and compact in structure, convenient in maintenance and installation, and strong in work reliability;
B. The paper return shaft, the guide roller and the two bottom rollers are equipped with hydraulic disc brakes, which assist the brake during emergency braking and share part of the braking torque. Reduce the braking load of the motor, increase reliability, and install an accumulator;
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.
