Four release and one rewinding machine operation program ---

Second, the machine starts
1. Press the warning button and delay for about 2 seconds. At the same time, the alarm sounds, and then press the start button to start the machine.
2. When the machine starts, fine-tune the discharge roller to ensure that the material is flush at the receiving roller. During the fine adjustment process, the gear is not rubbed against the periphery.
3. When the machine is running, no objects are allowed between the ultrasonic probe and the material axis. This will cause the machine to stop working.


Third, automatic acceleration
When the accelerator button is pressed and delayed for about 3 seconds, the machine automatically accelerates to the required maximum speed (set in the touch screen), and the deceleration button is pressed once during the acceleration process to automatically accelerate and stop.

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.

Stretching device after cutting the web
The purpose of stretching after slitting is to stretch the sheet in the lateral direction and to separate the cut sheets from each other.
Construction
After the cut, the stretch is achieved by the wrap angle roll. The wrap angle roll includes a stretch roll. The first spreader roll is above the cut sheet and the second spreader roll is below the sheet. Both rollers are mounted on a frame that is used to adjust the stretch.
The spreader rolls above the sheet have good curvature. The spreader roll is equipped with a bend control device. The hand wheel and screw mechanism are used on the maintenance side to control the direction and tendency of the bend.
The segmented spreader rolls are under the sheet of paper. The segmented stretch roll is placed over an arcuate roll mounted on a steel beam. The cylinder is mounted below the segmented spreader roll. The bending curvature of the spreader roll can be modified by adjusting the gas pressure to adjust the cylinder.
Stretching principle:
When the sheet passes under the first roller, the sheet is guided from the center to the outside by a curved roller at each slightly different angle. At this time, there is a small gap between the cut sheets. When the sheet is placed over the second roll, the sheet encounters an arc of the opposite direction, which allows the sheet to remain parallel through the gap.
The stretching effect is mainly controlled by changing the wrap angle of the spreader roll. In addition, the stretching effect can also be controlled by changing the bow position of the stretch roll to control and change the arcuate curvature of the segmented spreader roll. The spreader roller is driven by a separate drive motor through a V-belt. The speed of the stretching roller is the same as the speed of the rewinding machine.
