Printing unit (four ceramic anilox rollers,four doctor blades)
Printing department is composed of adsorption bellows,printing
roller,anilox roller,rubber roller(or scraper). The transmission in
all units adopts the cross slider structure(In particular,the
pressure adjustment between the anilox roller and the rubber
roller,and between the anilox roller and printing roller adopt the
cross slider structure),decrease the noise,more stable
transmission. The vacuum feeding system in the whole course,it can
realize full plate,bending board printing,there is no need to
leave traction margin on both sides of cardboard,reduce cardboard
waste.
The printing roller is made of high quality steel,with grinding
surface and hard chrome plating.
Balance correction,smooth operation.
Scroll hang plate,the left and right sides adopt locking device so
that the plate to be accurate.
Loading and unloading printing plate,foot switch electric control
positive and negative rotation.
Anilox roller(ceramic anilox roller,mesh number can be selected
according to customer’s requirements)
The mesh consistency,the ink uniformity.
The interval of anilox roller is equipped with self-locking
structure,adjustment range is 0-12mm.
Anilox roller is a quick change device(convenient for
maintenance,saving time and effort).
Phase adjustment mechanism
Planetary gear construction.
Printing phase is adjusted 360degrees by computer and electric
digital control(both of operation and stop can be adjusted).
The lateral phase is controlled by computer and electric digital
control with a control range of ±10mm.
Printing roller phase is adjusted by frequency converter,quickly
reset and adjustment of high precision.
Automatic reset system after the printing plate is cleaned during
the printing process.
Quickly printing plate hanging function.
Inking circulation structure
Pneumatic diaphragm pump,stable inking,simple operation and
maintenance.
Pneumatic diaphragm pump cannot pump the ink when the rubber roller
and anilox roller are not closed.
Abnormal ink supply,warning light lights up.
Ink filter screen,filter impurities.
Stainless steel ink tank.
Ink saving function,changing ink color or cleaning each unit each
time can save ink.
Automatic cleaning function,after ink recycling,automatically
switch to clean with water.
Printing phase fixing device
Electromagnetic clutch brake mechanism,when the unit is separated
to adjust the phase or be cleaned,the brake mechanism restricts the
gear rotation and keeps the original tooth position fixed.
The power transmission of the pressure roller adopts cam bearing
transmission,which reduce abrasion and makes the transmission more
stable.
Economical doctor blade system,saving costs and controllable ink
volume.
Automatic switch setting of inking supply and cleaning procedure.
Electric adjustment of scraper pressure to control ink
quantity(production adaptability).
