Rewinding Machine operating procedures -  Job preparation.
1. The operator arrived at the post 10 minutes in advance.
2. Check and understand the operation of the equipment, check equipment hazards, check equipment hygiene and on-site hygiene, and make a good inspection record.
3. Understand the production situation and quality of the class before the class, familiar with the work site.
4. Familiar with process standards, master product quality requirements, variety specifications, dimensions, roll length, indicators and tasks.
5. Do personal safety protection and equipment safety protection.
6. Carefully implement the handover system and make a record of the handover.

Four release and one rewinding machine operation program ---

Second, the machine starts
1. Press the warning button and delay for about 2 seconds. At the same time, the alarm sounds, and then press the start button to start the machine.
2. When the machine starts, fine-tune the discharge roller to ensure that the material is flush at the receiving roller. During the fine adjustment process, the gear is not rubbed against the periphery.
3. When the machine is running, no objects are allowed between the ultrasonic probe and the material axis. This will cause the machine to stop working.


Third, automatic acceleration
When the accelerator button is pressed and delayed for about 3 seconds, the machine automatically accelerates to the required maximum speed (set in the touch screen), and the deceleration button is pressed once during the acceleration process to automatically accelerate and stop.

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.
