Second, the main structure of the winder

2.3 Rolling Department

3, unloader
Nowadays, with the increase of the speed of the winder, most of the winders are equipped with unloaders, which are used to push the rolled paper rolls from the support rolls and unload them on the ground. It has many forms, the most common ones are the unwinding station and the unwinding pendulum. Its control mainly depends on air pressure or hydraulic pressure. The thief of the unwinder can be selected according to the number of operators, the size and quality of the core. The advanced foreign rewinding machine can automatically control the positioning of the mandrel and mandrel and the cutting of the paper, which can save auxiliary operation time and improve production efficiency.
4, transmission mechanism
The speed of the paper-feeding machine of the winder is generally about 15 to 40 m/min. In the process of raising the speed of the paper from low, we require the speed of the vehicle to rise, so that the paper roll can be avoided due to the fluctuation of the tension. The tightness is inconsistent. Uniform acceleration is required for breakage or shutdown. During the acceleration process, the average acceleration is usually 0.23~0.37m/s, and the acceleration time is usually 50~60s. In the braking process, the deceleration is 0.42~0.75m/s and the braking time is 40s. In order to meet the shifting requirements of the winder, most of the rewinding opportunities are driven by DC motors. In the previous rewinding system, a DC motor generally controlled two supporting rollers, and in the current rewinding machine, Development and research have started with two separate motor control rolls, which can control the speed difference between the two rolls, which is beneficial for taking up the appropriate tightness of the paper roll.

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.
