The feature of super thick overall cast iron walling and staunch
cast iron
foundation as well as the typical offset printer structure ensure
the high-speed
operation stability, high precision, long life and enough printing
pressure.
Additionally, the vibration-free running of the dampening and
inking rollers and
the roller bearings ensure the long smooth running and constant
printing quality
to the press.
The rubber cylinder adopts the large-scale offset printer,s usual
impression
technology-three-point suspension technology with accurate and
reliable pressure
adjustment. The cylinders are adjusted independently without
interference to each
other, protecting the roller bearings.
The outside high precision gear drive and cylinder bearer are
adopted to ensure
the steady printing pressure transmission and stable rolling of the
roller as well as the
large area of field printing, clear screen dot duplicating and
petty characters printing.
The overall machine is supplied with the oil in an collective way
so that all the
gears and bearings are lubricated from time to time when starting
up or in operation
(single-color press adopts manual pump).
The whole inking unit is composed of 15 inking rollers, including 4
plate rollers
of different diameters, featuring quick system response and
excellent ink distribution.
The ink fountains are zone controlled by ink fountain key and the
individual

this way, it
guarantees enough ink reserve and uniform ink supply.
Adopt big machine's special feeder and paper feeding plate,
including elaborate
two suction nozzle pick-delivery-type sheet feeding unit and
conventional uploading
brush, and sheet pressing roll belt friction-type paper feeding
plate. The roller wheel
type side drawing guide sheet transfer unit adopts standard upward
swing sheet
transfer unit, and the holding tooth will close up at the cam,s
high point, thus the sheet
transfer is stable and accurate.
The quick plate clamps with the locating pins on the plate cylinder
is convenient
for the quick loading and unloading of the printing plate. Remote
controlled
adjustment device can adjust the printing plate in the
circumferential, axial or
diagonally direction without stopping the press. The axially
adjusting allowance is
±1.5mm, circumferentially adjusting allowance ±0.67mm, and bevel
adjusting
allowance ±0.45mm. Particularly, the registration adjustment in
diagonal direction is
HGPM,s own proprietary technology.
For the half high pile delivery, the number of the gripper bars is
increased from
2 to 5 and the extended delivery distance is in favor of the
thorough drying of the
printings.
