Features in the four-shaft front roller feeding unit

• The four-shaft front roller feeding system makes feeding more accurate. Feeding thin and bending sheets becomes easier.
• Continous feeding, skip feeding or single-sheet feeding is possible. The attached counter can accurately record the quantity of production..
• The front edge fo the sheets is taken as the baseline so that mechanical errors are reduced ant and printing and slotting can be more accurately positioned.
• The air flow and pressure are controlled by a frequency converter to satisfy the requirments for the thickness and the size of the sheets.
• Double paper feeding system, more stability during feeding.
• The upper paper feeding roller adopts quick-change system. The roller and gudgeon block are separated. The whole roller an be changed when necessary. Easy maintenance.
• The lower paper feeding roller can be adjusted manually, and the adjusted date will be displayed on the dial.
• The highly efficient de-dusing device can substantially remove the dust and dirt from the printing surface of the sheets and enhance the printing quality.
• The rear sheet holder can move forward and backward, upward and downward through electric control. Adustment can be made quickly.
• The powerfuly cylinder main lock for the whole machine makes the system the systme more stable.
• A motor start protective device is adopted for the machine. When not properly secured, the machine will not start up.

Features in printing section

• Applies hanging plate printing system, easy for plate changing; and has pedal swtich, easy for plate hanging.
• Has anilox roller plus paper feeding system auto lifting device ( in feeding anilox roller drops and contacts printing plate, whereas in stop, it rises to separate from the printing plate.)
• The cirumferential adjustment mechanism of the pringting platen applies planetary gear structure.
• The printing phase can be subjest to a ***-degree adjutment by means of a transducer a touch screen control or in an electric numeral way (in both running and stop statuses)
• The inking roller uses wearable high-precision right chrome anilox roller.(the ceramic anilox is optional)
• The rubber roller is formed by means of  wrapping a steel pipe with wearable rubber, and has good ink transfer effect.
• Has auto low ink warning, avoiding damaging the rubber roller and anilox roller.
• The space between roller can be adjusted by eccentricity gear and this leads to compact structure and accuracy location. The space between roller and cylinder can be adjuted manuaally. The date is shown on the dial.
• The transverse position can be adjusted in an electrical numeral way, with total distance adjustable from right to left being *0mm.
• Printing phase fixing device applies electromagnetic clutch braking mechanism. When the machine table separate or adjust the phase, the braking mechanism restricts the table rotation and maintains original gear position fixin point.
• A 5.7" touch screen is set on the control panel, easy for operation.

Dual-scraper Inking System

• Locked by air pressure or cylinder adjustment, automatic compensation for blade wear, obtaining uniform effect of ink scraping.
• Blade chamber is coated with Teflon for anti-corrosion and anti-sticking, making it easy for ink trasfer and cleaning.
• With actual meaning of "Sealing Completely", in particular applying to volatile solvent, reducing ink cost and improving the working environment.

Features in slotting section

• The axial adjustment of line-press wheel, paper-feeding wheel and slotting kinife head has touch screen date predefining and manual adjustment tow manners, being prompt and accurate; and the next order sizes can be predefined during production.
• The scoroing roller, the feeding roller and the slottter seat move axially, guiding by a rolling straight guiding track so that movement is stable and positionning is accurate.
• The slot phase applies transducer and touch screen control, can be electrically regulated within ***-degree in numeral (both in running and stop), has restoration fuction; and can store orders.
• A *0.4" toch screen is et on the control pannel that can control the feeding section, printing section and soltting section, easy to operate.
• The lower lay-on roller and The lower slotting cuter roller adopt eccentricity geat system and this leads to compact structure and accuracy location. The space between lower lay-on roller and lower slotting cutter roller can be adjusted manually. The date is shown on the dial.
• Has central knife moving, being able o produce large-sized *-piece cartons.
• The slotter shaft and the feeding roller shaft are hard-chrome plated and finely polishe, enjoying long lifespan and no vibration during moving.
• Punching device is optional according to user's necessity.

Features in die cutting unit

• The rubber roller is designed as folded rubber cushion, providing convenience and ease for removal, installation and replacement.
• The rubber rooller can move axially *0mm leftward and rigthward, controlled by a hydraulic control system. The displacement of each rount of rotation is adjustable to ensure a steady and reliable movement.
• A frequency converter is adopted at the pahse position of the cutter unit. The touch screen and the electric-digital device provice ***-degree adjustment. Order forms can e stored in the system.
• The transverse position of the die can be regulated through the electric-digital adjuste. The total adjustable distant is about *0mm.
• A PLC touch screen is used to control the spacing beween the die roller and the rubber roller.
• A speed difference offsetting device is adopted that can automatically adjust the rotaion speed of the rubber so that the die cutting carton has exactly the same shape as the die shape.
• The cores of the rubber roller and the die roller are made from quality steel and are hard-charome plated and finely polished. The track path is balanced and calibrated to enhance the stablity of movement.

Features in accumulating section

• The whole procedure of pilling cardboards is automatically finished in control system.
• Paper receiving arm can be manual or auto operated.
• Cardboard feeding speed is adjustable according to production need.
• Reliable safety prevention is available when the section is in work.
• The rear blocking plate is electrically adjustable in both running and stop atatuses.
