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.
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 ---
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.
