Automatic Flexo Printer Slotter and In-Line Folder Gluer is used to make complete corrugated
cartons automatically after the corrugated paperboard is slotted to replace manual gluing and
folding .The machine consists of a gluing unit, folding unit, automatic pressing and laminating
unit and counter ejector unit. After corrugated paperboard is slotted , the gluing unit will supply
glue to the corrugated paperboard flap, and the laminating unit folds the board and laminates it.
The edge presing roller then presses the edges and the steel roller pre-presses it, then after
folding ,the corrugated boards are reshaped by a shaping board (patting the fronts and back of
the boards).Following this, the counter ejector sends out the pile of card-board and counts the
quantity ,then binds the pile of cardboard.The gluing ,folding, pressing ,laminating and counter
ejec-tor workflow can greatly improve working efficiency and increase the benefits of manufacturers
through precise shaping after folding and precise operation of the counter and ejector unit.
The configurations of the machine
Lead Edge Feeder
* Fast setting of feeding speed, minimal maintenance, absolute safety and easy operation.
* Adjustable blower pressure can be used for different types of paper .
* Paper is delivered at the same speed to the lead edge puller to avoid wrinkling due to pressure.
* Adjustable air flowf for the blower which helps to feed paper into the machine.
* Fitted with brushes to remove dust from the surface of the paper.
* Double-side positioning of the paper sheets.
Vacuum Dust Remover
* High efficient vacuum dust removing device can vacuum and clean the dust quickly.
* Printing unit can be rotated a full 360°when paper is in motion or stopped,motorized
* Printing assembly can be manually adjusted up to 12.5mm.
* Pneumatic down-pressure touch-board. The lines of high quality ceramic anilox roller
can be from 200 to 350 lines.
This unit features a pneumatic down-pressure touch-board.
* The metering and the anilox rollers are automatically raised by the safety system when
the air pressure stops.
* Enclosed chamber (doctor blade) system and rubber roller can be specified for ink
supply system at customer`s option.
Vacuum transfer for printing unit.(bottom sucking)
* Conveying Device consists of one conveying box with groups of rolling wheels and
strong air vacuum sucking transfer system. The paperboard are sucked on the wheels
stably and transferred by them, which can transfer the small sized and thin paperboards
more smoothly. The printing area on the paperboard can be avoided being scratched
without pressing pull rolls. Dryer can be installed to dry ink immediately.
* Sucking and exhausting air device and tube.
* The pressure between rolling wheel conveying box and printing plate cylinder can be
Hot air drying system for printing unit
* The heating from electric heating tube (18KW) transferred into the hot air cover.
The specially-designed net below the hot air cover blow the hot air into the
paperboard surface evenly to make the printing result more colorful.
* Hot drying air. The air gate is divided into three parts and it can be adjusted
according to the paperboard size .
* Air cover has two layers. The inside cover blow hot air and outside cover suck air.
The extra water vapor and heating air can be exhausted.
* Hot aie temperature can be adjusted automatically.
Enclosed chamber system for printing unit.
* Ink supply by pressure,double doctoring blade to make the ink supplied on the
net roller even and equal.
* Pneumatic double film separation pump to fill in the ink and pump out the remaining ink.
* Only 20grame pressure(0.2N) on the length of every cm can get very ideal ink doctoring effect.
* To reduce the wear of anilox roller, doctoring blade and blade edge sealing
material to save ink doctoring cost.
* To use patented blade edge sealing mechanism.
* To use a “sttipped doctoring blade system” to change the blade rapidly.
* Without the influence of anilox roller diameter, only with the help of the side faces of
chamber system and each side face will match with one part of inking roller diameter
and obtains the most ideal ink doctoring result.
* Quick and convenient change from working status into washing status.
* The slotting unit can be rotated a full 360°and incorporates a cutting depth
scale which directly displays the adjusted position of the front and rear knives.
* The creasing and slotting shaft can be adjusted up or down.
* Automatic setting of slotting knives with order memory functions.
Rotary Die Cutter
* Slotting knife roller moves both left and right
* Automatic switch on/off of pressure
* Can be used with equalizer
* Die cutting cylinder made of superior material with extra hardness.
Computerized for whole machine
* The whole machine with PLC control system, each printing unit is equipped with
an 5.7” screen touching panel, and the slotter has a bigger and colorful one with
the size of 10.4”, through which we are able to make and save more than 500
production orders. Another central control system can be expanded to connect
local area networks, and achieve distal maintenance function.
* Computer control for the movement of the front stop board in the feeder, relevant gap
between units, processing phase of each units, axially movement, clutch pressure, and
air sucking function. And all the units are equipped with safety device and error displayer.
In line folder gluer
* Motorized-operated gluing unit and human-interface input controls.
* Gluing roller works at the same speed as the main machine. When the machine
stops, the gluing roller runs by itself so that the glue on the roller will not dry.
* High quality gluing system imported from USA or Europe at customer’s option.
* Motorized-operated movement of folding beam, controlled by interface or computer
* Adjustable folding pole can match different corrugated board’s specification.
* Springy upper belt pressure roller avoids loss of hardness in corrugated cartons.
* Lower synchro-belt allows corrugated boards to go in smoothly .
* Corrugated carton guiding square and side roller.
* Air blower blows the boards down, while front patting boards make the front and back
flat and neat.
* Motorized adjustment of left and right side of stacker so that corrugated cartons are
piled in the middle.
* Motorized-operated movement of front and back stop board.
* Piles of 10-40 cartons can be set and sent out .
* Motorized adjustment of the height of sheet pressing frame.
* Pushing by inserting from the bottom, precise counting.
Automatic kicking feeder
* PLC control of the main motors in the paper feeder unit,userfriendly interface and
LCD display screen make operation easy.
* Front paper block,side positioners and rear block are all electronically controlled.
* Blower system features extra blower to add air volume if its needed.
* Additional sheet-in brush dust cleaner.
* Double sheet-in roller structure.
Semi-computerized for whole machine.
* The whole machine with PLC control system, the feeder is equipped with an
5.7” screen touching panel, and the slotter has a bigger and colorful one with
the size of 10.4”,through which we are able to make and save more than 990
