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 ---
The specific technical structure is described as follows:
3. Double curved roller section:
Mainly composed of bracket, double arc roller, worm gear adjustment device, angle gear, air motor and other devices
After cutting the paper, it enters a set of curved roller stretching assembly, which is mainly composed of two curved rollers and an adjusting mechanism. The adjusting mechanism is driven by a pneumatic motor, and through a set of angular gear mechanism and two sets of worm gear reduction mechanisms, according to The wrap angle between the web and the curved roller needs to be adjusted at any time. The curved roller is introduced from abroad to ensure its performance. This system effectively stretches the web, eliminates wrinkles, and separates the paper rolls.
4. Automatic paper feeding department:
The guiding paper-feeding roller and the compressed air and the guiding plate are adopted, so that the paper head can smoothly and quickly and accurately complete the paper-feeding action on the uniform air cushion generated by the guiding plate and the compressed air, and between the two bottom rollers is used between the conveyor belt and the bottom roller. Friction drive, so that the paper head is close to the surface of the bottom roller, and the paper-feeding action is completed under the action of compressed air.
Design and application of constant tension and load distribution control for winder---
2. Main research content
(1) On the basis of understanding the working principle and production process of the rewinder, determine the AC drive configuration scheme of the rewinder and the common DC bus power supply mode.
(2) In view of the influence of the change of the winding diameter on the tension during the rewinding process and the phenomenon of paper break and loose paper during acceleration and deceleration, a composite tension control method combining direct tension and indirect tension is proposed, and the real-time calculation and dynamics of the winding diameter are designed. Torque compensation program that effectively corrects tension disturbances to ensure constant tension during rewinding
(3) Software and hardware design to complete the pressure control of the platen roller”
(4) After detailed analysis of the causes of the load distribution of the bottom roller motor before and after the detailed analysis, determine the master-slave control scheme of the two motors, design the load distribution control system.
(5) Establishing a profibus-Dp network system, designing communication between pLC and inverter! Op operation panel"
(6) Using STEP7 to design the software of the rewinder control system, using ProTool to compile the entire monitoring system screen"
