Structural features and operating
principle:
ZY8160-8320 Intaglio printer in group
or in combination consists of 4 main
units-feeding,printing ,drying and
delivery units.
Feeding unit
Feeding unit adopts rotary centering
feeding apparatus and automatic tension
control.Tension can be autimatically
changed with diameter of paper web
and speed to keep paper running steady
without wrinkling.
Printing unit
Printing unitis made up of drive gearbox,printer
frame,impressing mechanism,squeegee
apparatus, paper feeding system,etc.
2.1 Driving mechanism
Driving mechanism driven by a FM speed-regulating
motor drives gearbox through universal
coupling and driving shaft.
2.2 Gearbox
The driving shaft drives plate cylinder
to rotate at a variable speed via
spiral bevel gear,cylindrical gear
and gear at the output end of shaft.Traverse
chromatographing of plate cylinder
is controlled by moving cylinder with
manual speed regulation (plate with
shaft).
2.3 Printer frame
Printer frame is made up of right
and left solid cast-iron wall plates,intermediate
support,guide roller,color duct,etc.The
stainless steel duct storing ink is
driven through worm wheel,worm,gear
and gear rack to move up and down.
2.4 Impressing mechanism
Pressing rubber roller drives movable
shaft support via small gearbox,nuts
and screws to adjust height of rubber
rollers in correspondence to diameter
of pattern roller.
2.5 Squeegee device
Print ink can be directly distributed
on the plate cylinder and excessive
ink must be scraped off with aluminum
blade to avoid ink to be splashed
on prints during operation.Squeegee
device can rotate from top to bottom
and from front to back and inversely
in correspondence to diameter of the
cylinder.Blade and printing roller
should have a good contact to maintain
a certain pressure.At the same time
the device can also travel across
plate cylinder.
2.6 Paper feeding system
Paper feeding system comprises three
units-guiding system for paper feeding,guiding
system for color-printing and guiding
system for paper delivery.Prints are
transferred by aluminum guide rollers.In
the guiding system for color- printing
two guiding rollers are electrcally
driven to realize up and down movement
and changing length of paper running
between numbers of printing color
through worm wheel,worm and guide
roller on precise roller screw,thus
obtaining accuracy of longitudinally
chromatographing.3.Drying unit
The machine adopts electric hot air
drying and residual heat (Electric
heating power 18kW/set)with the features
of uniform drying and shrinkage,high
speed,and economized power.
4.Delivery unit
Driven by a motor of 40 Newton torque
the delivery unit provides floor-standing
two-roller friction delivery and two-position
blowing shaft suspending delivery
for user to choose.Unwinding roller
for web and taking-up roller all air-blasted
to perform longitudinal and traverse
movement through nut and screw adjusting
system.
