(3)Length-ways chromatically execute structure :dunle precisions to the ball bearing pole ,and the correction distance are 100mm single.
6. Press and print shaft :Integrate the shafts
(1)Mode of press and print:the gas-vat power of press and print can be adjusted freely,double sides press adjusted .
(2) Setting for the press and print shaft:Adopts adjust -center shaft and own the speediness disassembly structure.
(3) Orientation for the press and print shaft :own the steady location structure ,and defend flexible .
(4) Material of the press and print shaft :rubber material ,rigidity 75-80 degree,and rinse the colloid by resist impregnant.
7. Draw knife unit
(1)Adjust the draw knife :it can be controlled by manual for level direction ,upright direction or each point of view .
(2)Draw knife press adjusts:double gas-vat with inverse,range of the press is 0-50kg can be adjusted according to the requirement .
(3)Draw knife swing capacity when it is come and go :10mm
(4)Draw knife material :the big plate is made of aluminum ,and one of the draw knife plywood is made of aluminum ally ,the other is made of armor plate .
8. Printing ink
(1)Material and the forms of the printing ink box :made of stainless steel ,and the printing plate shaft is immerge the ink box directly .
(2)Adjust the printing ink box :gear and rack structure ,and can be upright elevation.
9. The circle structure of the printing ink box
(1)Start-up the septum and let the printing ink circle
(2)Space of a whole page is in a drought structure ,and it is the line-hole ,hammer-wind tube .
10. Dryness box
(1)Heating form :heating by electricity
(2)Structure form :mesh and gap model ,heat-wind circle and vent rapidly structure .
(3)Temperature control :automatic constant temperature control.
(4)Unlock mode :guide track mode ,open and close by gas .
11. Roller requirements :
(1)Adjustable roller with the instruction sheet :park in the front of the printing plate roller ,it can be adjusted through the level orientation ,and assistant the landscape orientation chromatically .
12. Drawing unit
(1)Draught for drawing
(2)Structure form :gas-press glue roller +active steel roller draught
(3)Driving form :it is droved by automatic stable power and motor drive controlled .
13.Chromatically system
(1)Control: Length-ways orientation :chromatically system Landscape orientation :echelon pole adjust .
(2)Check mode :reflect mode with double magic eye(have the glisten board)
(3)Pre-chromatically check: circle code
(4)Check precision : ±0.15mm
(5)Chromatically precision : Landscape orientation: ≤±0.15mm Length-ways orientation: ≤±0.15mm
III. Main feature:
1.The machine also uses in BOPP, PET, PVC, PE, NY and the paper and so on, has the fine film reel of printing performance, the material has multicolor prints continuously.
2.Non-axis justification, printing speed 10-120 meter, mechanical speed 150 meters.
3. Automatic color printing system, each control unit disposition independent microcomputer processor, but rapid accurate revision color printing deviation.
4. Mainly motor adopt frequency adjust.
5. Unwinding tension system, uses the completely automatic permanent tension controller and the magnetic powder brake control.
6 .Rewinding tension, uses the completely automatic permanent tension controller coordination bimoment electrical machinery control, the automatic double working station can make sure the machine change the fabric non stop.
7. Outside the independence sets at the heating, the closed cycle hot blast is dry, but uses electricity frugal 30%. The independent cold bellower cools.
8. Sectional type heating system.
9. The air operated stamping systematic and independent air operated blows the ink system.
10.Printing ink auto cycle system.
11 .Takes in and puts away the material axis to use the gas to rise the axis, the handling operation is convenient.
12. The printing link speed and counts demonstration.
13. The complete machine for the frame type high-test cast iron structure, the stability, the earthquake resistance line is good.
14. Has the color printing deviation indication, the system synthesis drift correction and the ultra difference reports to the alarm the function.
15.The electrical machinery transmission uses the synchronized belt transmission principle of work completely.
