Rewinding Machine operating procedures - Preparation for rewinding.
1. The crane operator and the rewinding personnel first check whether the information on the parent roll tracking slip on the base paper meets the requirements of the technical standards, specifications and specifications.
2. Check whether the labels of various paper diseases on both ends of the base paper roller are clear and consistent with the contents on the tracking sheet.
3. The crane operator should operate carefully according to the safe operation rules of the driving.
4. Place the base paper roll on the unloading frame smoothly, place the drum groove on the shaft head, place the track groove in the locked position, and connect it with the hydraulic coupling.
5. Jog the left and right shift buttons of the exit tray to bring the ends of the web to a position that can be trimmed (to be threaded).
6. The operator should make a detailed record of the paper (such as shift, shift, production date, roll time and paper roll code, etc.).

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 ---

 

Second, the main structure of the winder
2.1 Ejection Department
In the rewinder system, we installed the paper roll on the paper exit frame. In order to ensure that the width of the sides of the paper web is the same, we should be moving the seasoning when the paper roll is ejected. However, the paper roll in the new structure can be moved together with the paper exit frame, which ensures greater rigidity of the paper exit frame. In addition to manually moving the paper roll, we can also use the pneumatic, photoelectric device and electric method to adjust the axial movement of the paper exit frame, so that the cutting edge of the winder can be narrowed, and the manual adjustment can not be achieved. Requirements.
We have a coupling on the reel of the unwinding roll. When working, we can use a pneumatic device to connect the brake to the motor. We can know that when the high-speed winder is started, the required acceleration time from zero to 2000m/min can be completed within 50~60s, and the deceleration time required for braking is 40s. Or even shorter, so we need to consider the maximum diameter and the maximum braking speed of the paper-removing brake on the winder to reduce the paper loss of the paper-cut, or it will cause a lot of waste. In the selection of the brakes of the eject roll, we often use brakes for starting brakes, magnetic brakes and mechanical brakes. In the usual case, we use the combination of the brake motor and other brake devices. When we press the paper, the paper roll started by the DC motor can enter the acceleration and working state and can be operated by the braking of the DC motor. Control, the tension control of the paper web, in the case of emergency stop, we can use the DC motor and other brakes together to stop the paper roll at the fastest speed.
