Rewinding Machine Structure - Control Performance Indicators
The rewinder is the last process in the papermaking process. The performance of the rewinder determines the quality of the finished paper roll. A complete rewinder must have the following properties:
1. Adjusting mechanism of pressure of the platen roller
2, support roller torque program control
3. Tension adjustment mechanism
4. Electric drive "flexible" start and proper speed program control.
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.
Automatic rewinding machine speed ratio adjustment method ---
4. Adjust the internal toothed chain and external chain of the main gearbox to make the transmission of the whole machine more stable. When the roll paper rewinding machine is running, it is controlled by the automatic acceleration and deceleration program to start and stop frequently, and the automatic trimming and sealing operation is completed. Therefore, the stability of the gearbox transmission ratio is high. By tightening its internal and external chains, the chain can be prevented from slipping and skipping, making the speed ratio more stable during frequent acceleration and deceleration. The tensioned upper chain of the toothed chain can be moved up and down by a tool of about 5 to 8 mm.
