Guolian High Speed ??Slitting Rewinder Technical Description ---
The specific technical structure is described as follows:
3. Double curved roller section:
Mainly composed of bracket, double arc roller, worm gear adjustment device, angle gear, air motor and other devices
After cutting the paper, it enters a set of curved roller stretching assembly, which is mainly composed of two curved rollers and an adjusting mechanism. The adjusting mechanism is driven by a pneumatic motor, and through a set of angular gear mechanism and two sets of worm gear reduction mechanisms, according to The wrap angle between the web and the curved roller needs to be adjusted at any time. The curved roller is introduced from abroad to ensure its performance. This system effectively stretches the web, eliminates wrinkles, and separates the paper rolls.
4. Automatic paper feeding department:
The guiding paper-feeding roller and the compressed air and the guiding plate are adopted, so that the paper head can smoothly and quickly and accurately complete the paper-feeding action on the uniform air cushion generated by the guiding plate and the compressed air, and between the two bottom rollers is used between the conveyor belt and the bottom roller. Friction drive, so that the paper head is close to the surface of the bottom roller, and the paper-feeding action is completed under the action of compressed air.
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.
