Rewinding Machine safety operation guide -
First, prepare for work after taking over:
1. It is necessary to arrive at the post, check, and original record 15 minutes earlier. Comprehensive understanding of the above
The operation of a class of equipment, the quality of rewinding and safety.
2. Understand whether the previous class of paper is good; whether the class changes specifications, the weight and change
time. Check if the shift is cleared in the previous shift.
3, the middle and night shift rewinders must check whether the rewinding paper core tube and packaging materials are adequate.
4,Report the handover to the squad leader
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---
4 Research significance and content
Due to the application and development of frequency conversion technology and computer network technology in the field of industrial control, the establishment of AC drive control system based on field bus has become an effective way to solve the above shortcomings and limitations. Taking PLC as the control unit, the inverter is the execution unit, and the OP operation panel is the operating unit to form the all-digital field bus rewinder AC rotation control system. Based on this assumption, in order to reduce the investment, the original mechanical part and hydraulic part of the system are basically maintained, the original DC rotating system is transformed into an AC rotating system, the solenoid valve and some worn mechanical parts are replaced; and the OP270 man-machine interface is used instead of the machine. Buttons and analog meters, and a part of the mechanical buttons, so that workers can operate on the OP270 or on the console buttons, complement each other, increasing the flexibility of operation.
