Main Configuration

Plastic free paper coating machine Application

The plastic-free coated paper is applicable to food contact packages because it is eco-friendly, water and oil proof.It is mainly used in paper cups (cold & hot drinks), paper bowls, paper bags (hamburgers, bread, or other food with oil), disposable food boxes, ice cream paper packs, etc. Efficient printing and effective improvement of production efficiencyCINOVA, as the new generation Cl Flexo Press from Raydafon, integrates the printing equipment with aerospace precision manufacturing technology. ClNOVA stands for high-level Cl Flexo press, featuring high production efficiency, user- friendly operation, smart production, energy-saving emission reduction, eco-printing, and others. Meanwhile, CINOVA is fully automatic and minimizes the order change time and energy consumption.

• One Key Setup

Using pressure pre-set and pre-register, the setup time has been reduced from 25 to 4 minutes, shortening the preparation time and effectively lowering the cost.

• Effectively save replacement and adjustment time.High-efficiency automatic splicing unit

The previous splicing unit requires the specially- assigned operator to watch over the splicing process and relies heavily on the professional skill of the operator. The improved splicing unit can complete the fully automatic rewinding and unwinding process only by inputting the web diameter and the length. This will minimize the reliance on the operator, improve production efficiency, and save time and cost.

Technical advantages

Using the internet and Al technology, Raydafon always strives for intelligent production. CINOVA adopts multiple intelligent devices with a smart system, which helps factories improve production efficiency and reduce labor and running costs.Intelligent printing control

• Intelligence system for error proofing and error correction

The function is intended to prevent the machine from damage caused by human errors. The Drive Motor Torque Protection function enables the machine to stop if the torque increases abnormally, thus avoiding damage to the plate. The Tolerance Protection function allows the device to control if position tolerance exceeds 3mm at both ends of the roller, thus preventing damage to the sleeve and mandrel.

• Automatic pressure compensation

The function adjusts the print pressure automatically when machine speed changes, thus avoiding the register tolerance and color difference caused by pressure changes.The function helps the machine stable print when the machine speed changes.

• Printing length measuring

The system will measure the print length in real time and send the feedback tension system. The system will automatically adjust to ensure variable print length, thus reducing the defect rate.

• Solvent concentration real time monitoring

The function monitors solvent concentration at the print unit and main heating oven. When solvent concentration increases to a certain limit, the system will trigger an alarm and adjust the air speed discharged to the exhaust pipe.

• Drive motor torque self-adaption

The function is intended to optimize unstable register precision caused by changing to a bigger printing plate or long-running machine. Using one-key motor optimization, the system automatically identifies the control parameters and enables the print roller motor to run stably.

• Speed self-adaption control system

By comparing the torque??value and adjusting the anilox??motor speed, the system will reduce the torque difference and eliminate the ink bar caused by a bit of heavy pressure printing.

• Print unit constant temperature Control system

With a unique structure and circulating cooling system, the print mandrel is protected from heat, which may cause the print dot to expand and the plate to dry. This enables the print mandrel to vary in temperature and enhances the plate service life, thus improving the printing quality and the rate of finished products.

• Job?memory?&one-key?retrieval

The function is intended for storing technical parameters for 99 jobs. The function enables the history job parameters to be retrieved easily. The print decks can move to a set position and start printing without further setting. When the machine stops, the last position of the print sleeve will be memorized. When the engine starts again, it will work from the same position.Raydafon has developed an LED-UV drying system to meet the client's unique requirements.LED-UV drying system is the twice UV drying process. Firstly, the surfacedrying stage, ultraviolet light and ink react; secondly, in the re-dying stage, the acidic substances produced in the first stage react with the unreacted ink to achieve a complete drying effect.LED-UV drying systems have an advantage over traditional heating methods regarding energy consumption, pollution control, and heating safety. With the ability to solidify at low temperatures, the system especially applies to heat-sensitive material, plastic film, and bills.

High?efficient?solidify	Instant?drying
High?print?quality	Solvent-based ink with a high content of pigment. Display colorful print effect
High?efficient?print	Pre-heating is not required. Instant drying when the print starts. Start or stop at any time
Eco-friendly?drying	Using long-wave ultraviolet (wave 380nm), it will not produce Ozone and bring no harm to the factory and the environment.
Iow?running?cos	Sealed in epoxy resin, LED-UV is durable. The UV solidifying lamp has a longer service life,not influenced by on/off time and working time. This will reduce the maintenance cost.
Low?energy consumption	Compared with mercury lamps, the LED-UV lamp consumes power only when drying. It is a low-energy consumption drying method.
