Abstract: Printing Machinery Principles - Process - Technology: The article mainly introduces the principle of differential speed for tension control in the tension area of gravure printing presses, and the tension control in the unwind tension area is mainly done by the unwinders and other related knowledge.

Tension zone control principle of gravure printing machine

The tension control in the tension zone of the gravure printing machine adopts the principle of differential speed, and the system adjusts the tension of the paper by controlling the running speed of the paper feeding force roller and the paper output force roller.

The tension control in the unwind tension zone is mainly done by the uncoiler. Tension control is a major function of the uncoiler, so the tension zone control principle is the same as the working principle of the uncoiler, by the clutch, tension roller and tension controller to form a closed-loop control system.

The printing tension zone is an important part of the gravure printing press tension control system and is the key to ensure the accuracy of printing registration.

The tension control of this tension zone adopts the principle of differential speed, and the system adjusts the tension of the paper by controlling the running speed of the paper feeding force roller and the paper output force roller.

At present, most gravure printing presses are synchronized with the speed of the paper feed force rollers and printing press operation, the paper out force rollers shaft end connected to the stepper motor, so as to achieve differential speed control.

Slitting tension area tension control is also very important, if the tension is not stable and can not reach the slitting accuracy, it will be scrap.

For this reason, the tension zone generally uses the same control method as the printing tension zone.

Its basic speed for the printing group also paper force roller running speed, slitting group out of the paper roller shaft end and stepper motor connected to achieve differential speed control.
