DESCRIPTION

1. Printing part full servo motor control : Press enables you to print any repeat within the minimum and the maximum size of the machine eliminating the old gears limitations such as obtaining any intermediary size. Furthermore, it's even possible to print different lengths within a suggested tolerance by using the same print sleeves, which is aimed at stretch ability of film. All the motors are synchronized to rotate at same peripheral speed and their angular positions are constantly driven by a centralized electronic system throughout the feedback of encoders.The system provides a very accurate positioning of the rollers,repeating exact positions and printing pressures for jobs already processed and recorded.

2. Quick Sleeve Replacement: This machine adopts TDS quick plate cylinder and an anilox roller replacement system. lts unique "gate"design ensures operators can quickly and safely replace sleeves with simple operation, requiring no tools or electrical mechanisms, reducing waiting time. Without using any hydraulic units, operation becomes safer. Fewer parts ensure high equipment reliability and convenient maintenance.

3. Stable and Simple Structural Design: The printing unit features a robust structure.The operation side is fixed by one high-precision linear guide rail, while the non-operation side is secured by two upper and lower high-precision linear guide rails. This design provides stronger support force for the sleeve mandrel. The printing unit contains no hydraulic mechanisms, and the entire operation process requires no tools. Through ingenious design, it ensures high reliability while minimizing the number of components. The color unit positioning mechanism is located outside the side frame, separated from the inking system, ensuring operational safety and reducing equipment maintenance difficulty.

FLYING SPLICE TURRET UNWINDER.

WINDING AXIS CONTROLS

SPLICE SYSTEM

² Twin axis, shafted type, unwinder for reels of maximum diameter 800 mm(film).

² Unwinder for reel mandrel of external diameter 96 mm (3" air shaft mandrel)

² Frames complete with base for jacking screws and holes for levelling and securing to the floor.

² Winding axis are center driven by A.C. motors.

² Tension control of the unwind axis by dancer roller system with pneumatic reaction, and rotary potentiometer.

² Web detector incorporated in the dancing roller, auto stop when paper broken

² Hand wheel for axial adjustment, the maximum adjustment amount is 20mm.

² Splice system composed by a lay on roller to stick the new reel to the substrate in use, and a cross knife to cut the substrate from the expiring reel.

² Reel change sequence activated by the operator throughout remote controls located near by the unwind section.

² Minimum external diameter of the reel permitted for the splice is 500 mm.

IN-FEED EDGE GUIDING SYSTEM

IN-FEED NIP ROLLER

PRINTING STAND

² Automatic edge guiding system is mounted before the printing section. 

² The system includes 1 (one) sensor for "left or right guiding".

² Nip roller, composed by a steel roller covered with rubber of hardness 65/70 shores, to lay film on the central drum. 

² The roller is mounted on sealed ball bearings, and is pressed laterally through two (2) pneumatic cylinders, one on each side, having independent pressure control manually adjustable.

² Central impression type, having framework prepared for maximum 8 printing units.

² Frames of stabilized HT250 cast iron, 120 mm (To be determined). thickness, connected by spacers and tie rods in steel and cast iron. A cast iron base supports all the structure and allows levelling and securing to the floor by jacking screws and holes.

CENTRAL IMPRESSION DRUM

PRINTING SECTION

TYPE OF INKING SYSTEM

² Chrome plating drum, protect it from external corrosion.

² The drum is supported laterally by tapered-roller bearings. In order to ensure the necessary eccentricity tolerance, the grinding and super finish process of the external diameter is carried out with the drum already mounted on its bearings and coupling flanges.

² Centralized manual lubrication of the supporting bearings of the central drum.

² Closed loop water conditioning system for the drum. The conditioning system integrates heat exchangers for cooling or heating the water.

² The plate and the anilox roller sleeve mandrel of each section are driven by a separate servo motor

² The pressure engage/dis-engage of the plate and anilox roller sleeve of each section is driven by a separate servo motor

² The horizontal adjustment of the plate roller of each section is driven by a servo motor

² Inking system by enclosed chambered doctor blade system. With ink circulation inlet and outlet, both sides are sealed.

² The two sides are sealed with special sealing blocks, which can effectively overcome the shortcomings of traditional rubber and sponge sealing blocks that wear quickly at high speeds.

² The enclosed doctor blade chamber is constructed a split design, the knife holder part can be easily separated from the main body, and the blade replacement is quicker and lighter

DRYING SYSTEM

DRYING SYSTEM BETWEEN THE PRINTING UNITS

FINAL DRYING TUNNEL

² The drying fans, the heat supplying units, the final drying tunnel and part of the entire ducting system of the dryers, is mounted on a steel framework located on the top of the machine and connecting the printing stand to the out-feed and chill roll assembly.

² A walkway, accessible from the ground by a ladder, is integrated in the steel structure assembly for ease of service for the units mounted on this section.

² Air box distributors mounted on the printing section, one after each printing unit excluding the last one.

² The box distributors are constructed in steel, and the air is blown onto the printed film by airstreams transversal to the web running direction. Exhaust cavity integrated for the evacuation of the air soaked of solvents. Edges protected by rubber seals to avoid air flows outside the drying area, and for proper evacuation throughout the exhaust system.

Closed type drying tunnel composed by 3 sections with integrated distributing chambers, mounted after the printing section.

The tunnel is constructed in steel, and the air is blown onto the printed film by airstreams transversal to the web running direction. Exhaust cavity integrated for the evacuation of the air soaked of solvents. Edges protected by rubber seals to avoid air flows outside the drying area, and for proper evacuation throughout the exhaust system.
