Rewinding Machine safety operation guide -
Fourth, joint operator joint quality:
1 found that the paper has a broken rewinder
2 peel off the damaged paper that affects the quality at the break of the rewinding and rewinding paper roll, and draw the paper edge Qi.
3 first cut a piece of paper, paste double-sided tape (or according to process requirements)
4 Stick the other side of the paper together, cut the paper, and attach the connector label.
Four release and one rewinding machine operation program ---
6. Check if the power indicator on the outside of the tension control cabinet is lit.
7. In the touch screen, you need to input or rewrite the following parameters:
1 counting length is cleared (if it is necessary to re-measure the length);
2 automatic acceleration speed (refers to the speed we reach after the automatic acceleration of the machine after pressing the acceleration button delay)
3 Automatic acceleration time (refers to the time required for the machine to automatically accelerate from zero speed to the design of the highest machine speed. The shorter the time setting, the faster the acceleration.)
8. Tension control: Set the tension of each discharge motor in the touch screen. The discharge motor mainly provides a reverse torque, generates tension on the paper surface, keeps the paper web flat, and the speed control of the discharge motor is a process of gradually increasing speed, but the line speed remains unchanged.
9. Each console has its own power switch, which can be switched on and off as needed.
10. The forward and reverse running buttons are set on the console, and the user can select the running direction according to the needs.
Rewinder mechanical structure and control process ---
I. Overview of the double-roller under the paper rewinding machine
The mechanical structure of the lower paper rewinding machine is shown in Figure 2-1. It can be seen from the mechanical structure diagram of the rewinding machine that the lower paper rewinding machine is fed into the paper web from below the rewinding machine. The paper web is wound around a support roll and then rolled up with a roll of paper. The paper is ejected from the unwinding roll, passed through the lower transfer roll, and then the web passes through the slitting mechanism at a fixed position, bypassing the front backup roll (press The second roller in the direction of the paper line or the back support roller is then wound on the take-up reel.
During the rewinding process, the paper web passes through the eject roller, and the tension force formed by the paper web pulls the paper roll toward the support roller, and the tension of the paper roll is stabilized by the action of the tension, and the rewinding machine can be made at a high speed roll. The quality of the paper roll can be guaranteed when taken. The lower thread rewinding machine can also control the pressure between the platen roller and the paper roll by changing the transmission torque difference of the two supporting rollers, so that the pressure of the finished paper roll can be controlled, and the quality of the paper roll can be Do a good job of control.
It can be seen from the figure that since the slitting mechanism of the lower threader rewinding machine is installed at a fixed position, this can avoid axial sway during the rewinding process, and also facilitates the control of the winding of the paper roll. The role of most of these rewinders in the Middle East is not very high, very close to the ground, the center of gravity, relatively low, due to the lower center of gravity, the rewinder can remain stable at high speeds, so this Types of rewinding machines are widely used, and most of the paper mills in China use the lower thread rewinding machine. Through many practices, this rewinding machine is also the best performance. And its speed can reach 2,500 meters per minute, the width is also long, can reach 10 meters, can handle the rewinding of different types of paper, from low basis to cardboard can be re-rolled. Of course, it also has its own shortcomings. The disadvantage is that because it is close to the ground, it is not easy for the operator to access the bottom of the machine. It is also difficult to guide the paper. Therefore, when the mechanical equipment is installed, a pit will be placed under the machine. In order to make the operator more accessible, the high-grade rewinding adopts the automatic threading structure, and there is no such problem.
