6 Colour Flexo Printing Machine for Napkin CI Printing, Embossing, Hot-Stamping, Folding & Cutting

about CRY 460B 6 Colour Flexo Printing Machine

CRY Series Napkin Printing Machines are designed for high-quality, multi-colour printing on roll napkin material. The fully automatic system efficiently handles material loading, deviation correction, printing, embossing, stamping, folding, and cutting, and is the ideal choice for businesses today seeking first-class production.

In 6 colour flexo printing machine, the press employs a central impression drum to deliver crisp and colorful prints. The press is equipped with precision helical gears for its strong, compact drive system with smooth transmission and quick, precise colour registration.

For small-sized napkin printing jobs, the two resin plates are held by the plate rollers for various napkin sizes. The pneumatic clutching system, when the machine is not in use, disengages the plate roll and ceramic anilox roller, making it easier to operate and increasing efficiency.

The easy-to-use, high-speed machine provides better quality for sensitive multi-colour napkin printing.

Machine Structures:

1. Unwinding mechanism

Pneumatic Feeding System – Equipped with an individual motor and surface belt active unwinding for smooth operation. Precise tension control originates from the dancing roller system which receives direction from a high-precision potentiometer linked to a low-friction cylinder for maintaining constant tension and accurate feeding speed during the entire processing time.

2. Dust Removal and Napkin Calendering

• A combination of brush dust removal unit and low-noise dust collector provides effective and speedy vacuum function to eliminate dust from paper surfaces.
• Multi-layer napkins receive a shiny lamination finish through the calendering process to produce better printed results.
• The steel material for the quality calender roll undergoes heat treatment together with quenching to provide strength while extending its operational service life.
• The Scraper System cleans the roll surface effectively by eliminating impurities such as scraps and wool from the surface.
• The 6 Colour Flexo Printing machine uses a high-quality toothed chain type Continuous Variable Transmission (CVT) to perform precise speed regulation.

3. Deviation correction mechanism

The Photoelectric Deflection Correction system detects and follows and corrects lateral movement of deformable materials from their original path. The device maintains paper edges in precise alignment before introducing them to the print unit for exact and clean entry. Stable & Efficient System – Comprises an AC synchronous motor, screw mechanism, tail plate, and roller for smooth & accurate adjustments.

4. Printing Units

The printing unit of this machine employs a satellite printing system together with precision helical gears to achieve quick plate alignment as well as smooth transmission and high printing precision. The equipment enables the production of customizable flexographic plates and allows double-assembly roll operation that works well for napkin printing requirements. Water-based ink serves as the printing component of this system which provides an environmentally friendly option for superior print output.

Every single component functions independently which enables smooth machine operation even when separate units connect or disconnect from the system.

Key Components
1. Anilox Rollers

• The system contains six ceramic anilox rollers that customers can customize based on LPI measurement.
• A solitary motor maintains steady rotation of the system when the machine stops briefly to prevent both the ink from drying and roller damage.

2.Doctor Blade System

• Closed doctor blade chamber with an open ink supply for easy disassembly, efficient ink distribution, and simple cleaning.

3. Plate Roller

• Precise position calibration for easy and accurate plate application.
• The system features pneumatic systems that assist in automatic plate insertion and extraction process.
• The device automatically detaches itself when it stops running to avoid undesirable alignment.
• Equipped with 6 printing rollers.

4. Printing Colour Control

• The pneumatic clutch system enables each colour group to function independently so the remainder of the machine stays unaffected.

5. Speed & Colour Register Control

• Users can control printing speed through the operation of a frequency converter.
• The operator can now make manual adjustments to secure perfect colour registration.

5. Drying mechanism

The infrared air drying system reaches 3 meters in total length while helping users save energy through quick and effective heating. Users can reach and maintain the oven because of its pneumatic opening system.

6. Embossing

A unique frame construction of the embossing unit allows users to easily perform dismounting and mounting and reset the entire unit smoothly. Quick maintenance and changeover operations are possible through this system. The system includes one fundamental steel-to-wool peripheral embossing roll set that ensures high and exact embossing performance.

7. Hot-Stamping

This is rotary stamping, hot stamping, the Stamping temperature is based on the foil Property. The jump stamp designed for small area stamping( within 8cm).The rotary hot stamping equipment performs foil stamping with exact precision because of the foil material properties. The machine incorporates a jump stamp design to address small-area stamping batches up to 8 cm thus enabling precise decoration or branding of napkins.

8. Folding

This system enables users to achieve accurate dimensions when processing different napkin shapes. Speed and gap adjustments happen on the pulling roller while the folding rollers easily modify spacing. Often the folding board requires no hassle for swapping thus maintaining operational continuity.

The cam system includes two functional components which can be operated independently to regulate clamping and unclamping times. The machine operates with enhanced efficiency through automated stacking that counts items for determining protuberance between every 1-3 pieces. The stacking application uses cylinders to deliver operation with precise control and sufficient space movements allowing smooth consistent functionality.

9. Slitting part

The ring belt knife located at the exit point performs the finished product cutting process to achieve clean and precise cutting.

A knife steel wheel implements its curved design to achieve balance which produces operation that runs silently. Users can adjust the belt knife tension together with its inclination levels to meet diverse cutting requirements and achieve better precision and flexibility.

10. Electrical control

A secure operational process is ensured through the integrated electrical control system. The machine runs on high-quality domestic motors which operate main and auxiliary operations.

Built-in viewing components with bells and horns warn operators before machine startup yet require at least a six-second delay before activating the machinery. The operation status is indicated through a red warning light to boost safety measures.
