Features

1, semi-automatic plate loading device, convenient for the operator to quickly and accurately plate, reducing the auxiliary time of printing plate loading.

2,paper thickness preset function enables the operator to automatically, quickly and synchronously adjust the printing pressure of each color group when printing paper of different thickness.

3,When the paper on the machine is not stopped to meet the printing requirements of the machine, replace the new paper pile; Reduce the printing of thick paper, long version of the live downtime to change paper time.

4, electrical use Mitsubishi mature process bus module CC-LINKffl line control, with communication between units to achieve contact.

5. The printing system composed of double-diameter impression cylinder and double-diameter paper transfer cylinder is conducive to the printing of thick paper and cardboard. At the same time, it reduces the number of paper handovers and is conducive to accurate overprinting.

6,centralized control of the DC electric pull plate control of the three directions (circumferential, axial, oblique) of the plate loading error, can be convenient and quick calibration of the four-color printing plate, reduce the printing auxiliary time.

7 and five-roller structure and moving intermediate rollers can effectively reduce ghost generation, fast ink balance and reduce the amount of over-plate paper.

8. The remote control ink fountain composed of 23 partitions is adjusted through the touch screen of the main console. It has the functions of ink quantity preset and job storage. It can easily retrieve relevant printing data and quickly enter the printing state.

Specific units

Feeder:
-Conjugated cam. Forwarding mechanism
controlled by linear guide rail makes machine
speed faster and more stable.
-Rotary valve with patent can clean paper dust
automatically and reduce the fault.
 

 

Printing Units:
- Both of frame and base are integral casting.
-High frequency quenching of gears guarantee
transmission accuracy.
- Helical gears, high overlap coefficient and low
noise.
 

Pneumatic Clamp Bar, Change Plate Without Tools:
-Tension of clamp bar is controlled by imported
hoses and disc springs, so that it is more flexible
for operation.
-Corners of cylinders are controlled by high
precision encoder. Plates will be installed and
dismounted by program automatically. Thus it can meet the long version and short version edition of the printing business needs.
-The tail of clamp bar is separated, so that it can
help paper more smooth.
 

 

Accurate Grippers:
 -After checkered high strength steel pads had been quenched, their life will be longer and replacement will be more conveniently.
-Wear-resistant soft pads ensure stability of paper handover and precision of paper transmission.
-High precision needle roller bearings and opening bearings improve stability of gripper system
