Rewinding Machine safety operation guide -
Third, the rewinding machine opening and closing operation sequence:
1. Start the rewinding machine and the paper edge blower motor to put the speed to the crawling speed. Tearing the web
Into one. The paper edge is wound into a roller according to the specified path, and the round paper web must be straightened. Loosen and tightly adjust, press the switch and the paper core tube to stick the tape. Stick the paper web to the paper core tube and start crawling. At the same time, the end of the paper roll is flat. The paper can not be wrinkled or discounted to ensure the quality of the rewinding. When the paper has broken ends, the joints are operated, the broken ends are connected and the joint quality is ensured.
Rewinding Machine operation safety regulations -
Fourth, other requirements in the production process：
5. When an abnormality or malfunction occurs in the production process, the machine must be turned off and checked and repaired. If the abnormality or failure is not handled, the workshop supervisor should be reported in time;
6. The perforation line must be inspected every half hour during the production process. If the perforation line is unqualified, it must be shut down immediately;
7. Every paper change must be weighed twice in the production process. If the weight of the original paper is quantitative, the texture and elongation are unstable, the number of knots should be adjusted at any time, the pressure of the riding stick should be adjusted, and the gearbox should be adjusted. The paper is elastically adjusted to meet the product diameter requirements, and the weighing is tracked to see if the weight of the product meets the standard.
8, at any time to patrol the quality of the product.
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.
