Four release and one rewinding machine operation program ---
Fifth, sorting out
1. After the work is finished, turn off the power and put the main power switch down.
2. Clean up the work area.
1. It is necessary to add oil to the bearings.
2. Use a manual grease gun to add butter to the bearing of the belt shaft once every six months; when the gear is missing butter, pay attention to add butter.
1. The winder has certain dangers, so it is necessary to pay attention to safety during operation.
2. Never touch the ultrasonic probe on the pressure roller.

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.

12Paper roll holder
When the paper roll is stopped, the paper roll is fixed at a certain position by the paper roll holder. The paper roll holder prevents slack and lateral movement of the paper roll. It is important to make a joint when making a customer roll. Roll holder on the take-up roll
The paper roll holder on the paper roll includes a spring-loaded plastic roll mounted on the paper cutter frame. When the paper cutter is in or on the middle position, the paper roll holder is placed against the surface of the rear bottom roller.
13 Automatic roll change
The rewinding device removes the paper roll from the winder.
The rewinding device cuts the sheet, pushes the paper roll onto the unloading station and fills in a new core for the rewinding.
The roll change can be started when the roll is decelerated. In the final stage of deceleration, the nipple guardrail and the platen roller rise to a high position. The unloader rises to the position where the paper roll is received. When the winder stops, the paper core clamp opens and rises to rise. The paper cutter is raised from between the paper rolls. The paper feed roller pushes the paper roll to the paper unloading station. At the same time, the paper cutter cuts the paper. The vacuum suction of the rear bottom roller sucks the cut sheet onto the roller. The core loader drops the new core onto the roll. The paper feed roller returns to its original position and the unloading table falls to the middle position. The paper core clip is lowered and closed. The platen roller and the nip guard are lowered. The winder crawls at a speed.
