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 ---
Fourth, normal shutdown and emergency stop
1. The emergency stop is faster than the normal stop speed. After the stop, the traction roller is automatically raised. The self-locking button is urgently deactivated. In the state of emergency stop, the machine cannot be started. We need to unlock the emergency stop before the machine can be started. . When the machine does not start (observe whether the start indicator is lit), we check the status of each emergency stop button.
2. When the discharge roller is about to release the material, it must be decelerated in advance. It is guaranteed that the speed of the material is just zero when it is finished.
3. Deflating Adhere the material on the receiving roller with tape, open the pressing shaft, lift the receiving roller, place it on a stable place, deflate the receiving roller, and pull out the receiving roller.
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.
