3) The rubber roll undergoes special grinding process, providing superb ink transfer effect.
4) The caliber of the rubber roll is adjusted by a self-locking system for a range from zero to 3mm.

5: Unit Adjustment Mechanism of the Printer Slotter
1) Planetary gear structure
2) Digital display type unit indication makes the operation convenient, intuitive and accurate.
3) Controlled by PLC with touch screen, the printing unit can be digitally adjusted at 360 degrees no matter when it runs or stops working. The precision of adjusting the unit reaches up to 0.35mm.
4) The printing roll is designed with a frequency converter to adjust the unit, providing fast auto-zero and plate adjusting as well as precise plate adjusting.
5) First, all units of the printer slotter and paper feeding system are automatically returned to zero with precision up to 0.5mm. Then, the unit will be adjusted roughly and automatically. After a trial of printing, accurate adjustment can be conducted to greatly reduce the waste paperboard.

6: Ink Recycling System of the Printer Slotter
1) A pneumatic diaphragm pump is used to supply ink stably. It is operated and maintained easily.
2) The pneumatic pump is not allowed to pump ink until the rubber roll and anilox roll are gathered up.
3) A filter screen is used to remove impurities from ink.

7: Fixed Device of the Printing Unit
1) When the unit is separated or adjusted, the pneumatic braking mechanism limits gear rotation and maintains the original gear fixed point.

8: Axial Adjustment Mechanism
1) The axial orientation adopts electrical adjustment mechanism with control range from -10mm to +10mm.
2) Digital display type position indication makes operation convenient, intuitive and accurate.

C: Slotting Unit of the Printer Slotter
1) Paperboard is not broken easily after creasing.
2) Its intermittent dial is manually adjusted.
3) The caliber of the creasing wheel is manually adjusted with the dial to show the adjustment data.
4) The slotting knife is 7.0mm wide. It is made of alloy steel and becomes gear shaped after heat treatment. Double trimming knives provide high sharpness and high precision.
5) The caliber of the slotting boss is manually adjusted with the dial to show the adjustment data.
6) The slotting unit adjustment mechanism is designed with planetary gear structure.
7) Controlled by PLC, the slotting unit can be electrically and digitally adjusted at 360 degrees.
8) The movement of the upper boss and lower boss are linked so the two knives stay aligned during movement.

D: Die Cutter of the Printer Slotter
1: Operating Function
1) Without die cutting, the die roll and rubber roll will be automatically separated via an air-cylinder eccentric device to extend the lifespan of rubber and cutting die.
2) Planetary gear structure
3) The slotting unit is controlled by PLC and electrically and digitally adjusted at 360 degrees.
4) Electrical and digital adjustment, transverse movement, adjustment distance of approx. 10mm
5) The printer slotter is equipped with a rubber correcting device, allowing the rubber roll to be corrected repeatedly for use. A belt is equipped for conveyance.

2: Die Roll (Lower Roll)
1) The outside diameter of the die roll (concluding the cutting die) reaches 239.2mm. Please note that different models come with different outside diameters.
2) The die roll is made of cast steel. It is surface ground and chrome plated.
3) Balance correction for increased stability of operation
4) The pitch of the screw hole fixed by a cutting die is 100mm in axial direction.
5) The suitable cutting die is 25.4mm high.
The thickness of the wood die varies from 16mm to 18mm for three-layer board and from 13mm to 15mm for five-layer board.

3: Rubber Roll (Upper Roll)
