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.

Fourth, summary
This chapter mainly introduces the mechanical structure of the double-backed roller rewinding machine, the working principle of the rewinding machine, the quality index and control performance index of the finished paper roll, and mainly analyzes the process of the rewinding machine from non-electrical convenience. Through the introduction of the quality index and control performance indicators of the finished paper roll, we can clearly understand that in order to optimize the quality of the paper roll, we understand the control system control objectives. Detailed analysis from the mechanism of operation: automatic program control of platen roller pressure; automatic program control of support roller torque; automatic tension control; electric drive "flexible" start and appropriate speed program control .
