Rewinder mechanical structure and control process ---
Third, the rewinding machine control performance indicators
The rewinder is the last process in the papermaking process. The performance of the rewinder determines the quality of the finished paper roll. A complete rewinder must have the following properties:
1. Adjusting mechanism of pressure of the platen roller
As the rewinder continuously performs rewinding, the diameter of the finished paper roll is gradually increased, and the weight of the finished paper roll is also gradually increasing, so that the contact points of the finished paper roll with the front and rear bottom rolls are also changing. So you can come to a conclusion like this:
If the pressure of the platen roller is kept constant and does not change, the pressure between the contact points of the finished paper roll and the front and rear bottom rolls is not guaranteed to be constant, and the change in the contact point causes the pressure generated between them to change accordingly. Therefore, if we want the paper roll to reach the best form, we must adjust the pressure exerted by the platen roller to compensate for the influence of the above two factors. Only in this way can the pressure between the front and rear bottom rollers and the finished paper roll be guaranteed. Variety.
2, support roller torque program control In the rewinding process of the finished paper roll, in order to obtain high quality finished paper roll, the speed control or the support roller torque should meet certain conditions, if the speed control is used, the support roller The speed between the two should be less than 0.2%. As the diameter of the paper roll increases, the speed of the two supporting rollers must be close. Only in this way can the high quality finished paper roll be rewinded, but some quick checking systems cannot consider this design.
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.
