Rewinding Machine Structure - Longitudinal Section
In the mechanical system of the winder, the slitting mechanism is a very important part of the winder. In order to ensure a straight and smooth cutting edge, the quality control of the finished paper roll plays an important role in ensuring the volume. It is easy and can reduce the fluffing during printing.
The slitting mechanism should be installed as close as possible to the paper roll so that it can produce a lateral movement more than necessary during the process of cutting the web without curling.

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.

Guolian High Speed ??Slitting Rewinder Technical Description ---

The specific technical structure is described as follows:

Part 1: Mechanical parts
The mechanical part mainly consists of a paper exiting section, a paper cutting section, a double curved roller section, a paper winding section, and an automatic paper guiding section.
1. Ejection department:
The structure is all welded by steel plate, equipped with an empty paper roll temporary storage guide rail. The paper-removing roller is locked on the paper-removing frame by the hydraulic operating lever. After the paper is finished, the paper-returning core is pushed onto the guide rail to replace the paper. Roll and start-up operation saves time. A bumper is attached to the end of the exit frame rail to reduce vibration and noise caused by the roll change.
The coupling clutch is located between the paper roller and the brake motor, hydraulically operated, and is interlocked with the hook safety anti-lift device. The crane hook cannot lift the empty paper return shaft before the roll paper completes the clutch has been disengaged. Security performance.
With brake generator drive and hydraulic control, the paper return frame is horizontally adjusted by hydraulic motor and has a lateral swing function with a maximum swing of ±50mm. The emergency brake uses a brake generator and a hydraulic disc brake. The brake is imported from abroad, with small volume, large braking torque and good reliability.
