Rewinding Machine safety operation guide - 

Third, the rewinding machine opening and closing operation sequence:

2. When the paper roll reaches the specified rewinding diameter (meters), the working speed will slowly drop.
After the paper roll reaches the specified diameter (meters), press the “stop” switch. After the quality inspector has measured the paper roll and the appearance quality, tape the outermost piece of paper with a tape and stick the paper. The inner core of the core barrel is pulled out (the thimble) and the bottom knife roll is lifted to remove the paper roll.
3, the rewinding machine should have a long downtime, stop the paper side fan, and do a good job of surrounding sanitation.

Design and application of constant tension and load distribution control for winder---

2Rewinder control research status at home and abroad
Rewinding machine is an important papermaking machine. It is usually installed behind the paper machine. Its speed should be 2-3 times of the speed of the paper machine, generally 1500-1800m/min, up to 300om/min. When threading, run at a maximum speed of 1:100. In order to ensure continuous paper and loose paper during the rewinding process, the tension of the paper web must be kept constant; in order to ensure the tight and loose quality inside the finished paper, the load distribution of the front and rear bottom roller motors must be performed. Therefore, the main performance requirements of the rewinder for the electric drive system are long-term linear speed, adjustable speed and wide speed range, and fast response.
The control of the early rewinder is mainly based on DC drive, and the DC control system is composed of discrete components or analog regulators to realize the above control functions. Since the transmission of analog signals requires a one-to-one physical connection, the signal changes slowly, which increases the overhead of computer speed and accuracy, and the anti-interference ability of signal transmission is poor, and paper breakage and wrinkling often occur in the production process. So in the mid-to-late 1980s, the analog regulator was replaced by a digital regulator, and the DC digital control system of the winder appeared. This control system is more stable, reliable and suitable for maintenance than the analog system, and is more suitable for interface with the factory computer. In the mid-1990s, most of the newly-invested rewinders in the domestic paper industry used all-digital DC-speed converters produced abroad, and the more famous ones were the 6RA7O series from Siemens and the 590 series DC-speed converters from Continental Transmission.
Due to the DC motor commutator and the brush, under the stable conditions, the design speed of the winder can only reach 1800m/mni, and the accuracy of the digital regulator is still limited to about 0.08% of the maximum speed, which can not meet the high speed paper. The matching requirements of the machine (the speed of the winder should be 2-3 times the speed of the paper machine). In the early 1980s, European and Japanese developed AC variable frequency speed control devices. This technology was successfully introduced to the United States in the mid-1980s and used in rewinders. The biggest advantage of the AC drive is that the AC motor is simple in construction and reliable in operation, and it requires much less maintenance and repair than DC motors.
