Vacuum Transfer in Printers through Wheel Drawer and Counterpart Roller Driven by Kinematics or Independent Servo Motor with Transmission to the Wheels, with Thickness Adjustment and Centrifugal Suction Fan.
In conventional cardboard machinery with pair roller traction, it is necessary to crush the sheet for effective traction, and even then, this does not guarantee precise color transfer.
Moreover, the crushed surfaces do not receive ink, and to achieve satisfactory results, it is necessary to use trimming.
Finally, when inline colors are not in use, the use of traction bands is required, leading to significantly increased changeover times.
Transferring sheets without grippers or traction bands represents an improvement in box parameters.
Advantages
We can upgrade your cardboard machinery with this technology, increasing productivity and improving print quality with a high return on investment ratio.
Composition
The system consists of the wheel drawer and counterpart roller, which can be driven by kinematics or an independent servo motor. Additionally, it includes: the thickness adjustment mechanism, the centrifugal suction fan to adhere the sheet to the wheels, the gate system to adjust to the sheet width, and the overall control.
THE RETROFIT OF CAVIFES PRINTERS CONSISTED OF:
These modifications have allowed for a 40% increase in the machine's maximum speed and a reduction in register variation from ±3 mm to ±0.5 mm. In conclusion, more production with higher quality.
