Gravure Coater

Gravure coater is composed of unwinding, storage, traction, gravure coating head, oven, rectification, storage, compound unwinding, compounding, storage, winding, heating, air duct and control system, among which the coating head and oven runner are the core technologies. The working principle of the equipment is that the rolled PETG/PVC/PP/TPU and other substrates are conveyed by the unreeling unit, and then enter the gravure coating head unit through the traction device, where the coating head is used to evenly coat the slurry on the surface of the substrate. Its principle is that the rubber roller is pressed above the gravure roller, and the film is pressed between the rubber roller and the gravure roller at the same time. At the same time, when the gravure roller rotates, the single-side scraper scrapes the slurry and transfers it to the film to finish coating, and then enters the oven for drying, and then exits the oven.

Equipment advantage

Gravure coater

1. The inflatable shaft chuck adopts mechanical chuck mode or gas cap structure, which has compact structure, abrasion resistance, strong bearing capacity and high reliability

2. Overroll drive structure optimization, reduce abnormal noise, improve bearing life

3. Double closed loop tension control, tension swing roller adopts low friction cylinder and electrical proportional valve, closed-loop pressure control

4. New anti-wrinkle technology, according to the design of the equipment sheet road configuration of a variety of forms of flattening roller, curved flattening roller, spiral flattening roller

5. The temperature in the bellows is uniform, the error is ±2°C, PID closed-loop adjustment, energy saving and environmental protection (electricity/steam/oil can be selected)

6. Through the fluid simulation of the bellows runner, the structure is optimized to ensure that the internal runner of the bellows has no dead Angle and no spiral flow, and the wind speed is stable and small fluctuation

7. Carry out fluid simulation and optimize the structure of the pipeline and air nozzle to improve the utilization rate of hot air and save energy consumption

8. Coating roller and comma scraper are designed for quick disassembly structure, easy to replace, clean and maintain
