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---
1. Rewinder structure and working principle
1.2 Working principle
The paper web is taken out from the paper take-off roller (in this paper, the lower paper feeding method is adopted), and the paper guide roller passes through the slitting mechanism, and is wound from the bottom between the front and rear bottom rollers, and then wound on the paper core. There are 1 support rollers in front of and behind the slitting mechanism, and the front and rear support rollers are equipped with tension sensors for measuring the tension of the web. The platen roller above the core ensures the hardness of the roll. Each component of the winder is driven by a separate motor. The working principle is 3: the original paper roll taken from the paper machine is placed on the unwinding roller, and the brake on the unwinding roller maintains a certain tension of the paper web, and Quickly brake the paper roll when the head is broken. The paper web passes through the guiding roller to reach the slitting device, and several slitting circular cutters divide the paper into the required width, and then send it to the take-up roller for rewinding. After reaching the specified length, the paper is stopped and replaced with a new paper core. Repeat the above process. The main structural parameters of the winder are the width of the paper that can be processed and the maximum speed, followed by the maximum diameter of the paper and roll, the method of cutting and the length.
It can be seen from the working principle of the winder that the motor of the take-up roller drives the corresponding take-up roller to rotate the paper-wound paper core, the diameter of the paper roll gradually increases, and the axial center of the paper roll increases with the diameter. Gradually moving up, the platen roller moves up and gradually reduces the pressure. The unwinding motor mainly provides a reverse torque, creating tension on the paper surface, keeping the paper web flat, and the speed control of the unwinding motor is a process of gradually increasing speed, but the linear speed of the paper web remains unchanged.

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.
