SUBLIMATION PAPER COATING

The machine has been specially designed, for Textile Sublimation Coating Application.
Sublimation paper is applicable to sublimation transfer, on which can print images with mirror reversal through inkjet printing, flat printing, screen printing, and gravure printing. Then transfer the image onto media by heating and pressuring, which makes ink on the paper become a gaseous state and combine with the media.

Key Features:
⦁ High Productivity
⦁ Easy Operating
⦁ Optimum energy consumption and ability to handle wide range of coating jobs
By perfect integration of the latest generation of automation electronics and mechanical components, the machine is made to deliver optimum performance and productivity with minimum left to right GSM Variation.

All Drying Zone hinged at rare end and enabled to get opened with the help of pneumatic cylinder. The heating tunnel will be accessible by catwalk throughout tunnel length. Idler rollers are driven by timing belt and pulley. Chrome plated/ Teflon coated idle rollers are dynamically balanced and polished provided in the tunnel to guide the web. Tunnel (which is exposed to the atmosphere) is connected to each compartment and insulated to preserve the heat loss. Adhesive drying is obtained by centrally connected hot air input on the web through air nozzles. The optimized airflow lessens heat consumption and avoids solvent retention in the coated substrates. Solvents evaporation is obtained by air nozzles, blowing air on the web in connection with the idle rollers, in order to ensure the drying, avoiding shaking or deforming of the web itself. The optimized airflow minimizes heat consumption and avoids solvent retention in the printed substrate. The central exhaust system is controlled by heavy-duty centrifugal exhaust blower to collect solvent contaminated air from all the tunnel units through central ducts/piping fitted with manual adjustable damper.

It is a Steel frame Structure with cross connection tie Bar Plates. Chilling unit ensures that mechatronics are synchronized. Distinctively designed, and precisely machined, strong and robust steel frame structure, maintains accuracy over long durability and ensures reduced vibration even with optimum line speed. Two chilling rolls are tightly synchronized together with ac motor Driven by AC vector drive. The rotary union is provided to ensure chilled water circulation uniformly.

Specially designed, low friction-low inertia, dynamically balanced idle rollers, mounted on low friction bearings to enhance rotational smoothness. Properly grooved, ground and balanced the rollers are made of specially graded anti-corrosion aluminum alloy.
