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.

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

2Rewinder control research status at home and abroad

AC drives were quickly successful in paper mills in Europe and Japan. Most major drive manufacturers now offer AC drives for paper mills. Most domestic paper mills use ABB, Siemens and other company's complete rewinder AC drive systems. . For example, the 6SE7O series speed control device of Siemens Company has achieved the speed control performance and has exceeded or exceeded the DC speed regulation performance and become the preferred solution for the transmission. The domestic rewinding machine AC drive started in the middle and late C9 of the 20th century. Due to the lack of understanding and research of the AC drive system of the winder, few mature sets of equipment were introduced to the market.
At present, in the domestic paper industry, the drive control system of the winder is gradually developing from the all-digital DC drive control system to the AC variable frequency drive control system. With the continuous improvement of the production process and speed of the rewinding machine, the requirements for real-time control and monitoring of the rewinding machine production process are becoming higher and higher. In order to reduce the large amount of wiring between the rewinding machine production site and the control room, the signal is improved. The transmission speed and quality of the fieldbus and human-machine interface began in the late 1990s for rewinders. Fieldbus is a new type of control system for all-digital, two-way communication. Due to the intelligent and digitized fieldbus devices, it fundamentally improves the accuracy of measurement and control and reduces transmission errors compared with analog signals. At the same time, due to the simplified structure of the system, the equipment and wiring are reduced, the internal functions of the field instrument are strengthened, the round-trip transmission of signals is reduced, and the operational reliability of the system is improved. In addition, the field control equipment has the ability of self-diagnosis and simple fault handling, and sends related equipment operation information and diagnostic maintenance information to the man-machine interface through digital communication. The user can monitor the running status of all equipments, query the cause of the fault, and Process parameters (such as tension) are set and modified according to the different requirements of the rewinder process. For this reason, the application of fieldbus technology and HMI technology to the winder has become the development trend of automatic control of the winder. With the continuous promotion of inverter, HMI technology and fieldbus technology in the application of winder and the combination of computer technology and communication technology, the design speed of the winder can reach 300om/min, the working speed is 2500m/min, and the winder Many of the manual operations have been automated, and manual operations have been greatly reduced. The degree of automation and control accuracy, control speed and system stability will be raised to a new level.

Belt rewinding machine design and working principle ---

14 change roll
The roll change blower is used to blow the cut sheet onto the core. On the platen roller, there are three blowing tubes on the paper core with a blowing tube under the paper core. When blasting is used, the paper will bypass the core at the beginning of the machine.


15 paper cut hair dryer
The web cut blower is used when the web must be cut quickly. The blow tube is located between the guide rollers.
The blow tube is activated by a safety photocell or a manually transmitted pulse signal.
1- Spreading roller
2- Adjust the paper wrap angle device,
3- Stretch roller bending direction adjustment device
A- paper web
B- First stretch roll bending direction
C- second stretch roll bending direction
Stretching device
The stretching device on the illustration is the basic position of the display. The web A passes directly through the spreader roll, which means that the web curvature is zero. The first spreader roll B is at an angle of 90 degrees with respect to the sheet. The second spreader roll has a camber at the base position when the cylinder pressure is 0 bar. The cylinder pressure can be read on the meter at the location of the control system.
