Gearless CI Flexo Printing Technology

High-Speed, High-Precision Solutions for Flexible Packaging

Changhong Full Servo Gearless CI Flexo Printing Machines are designed for high-speed, high-precision printing on flexible packaging and other roll-to-roll substrates. The machine integrates full servo gearless drive, automatic register control, closed-loop tension control, sleeve technology and centralized drying for stable production and fast job changeover.

CHANGHONG Key Features

Full Servo Gearless Drive

Each printing unit is independently driven by a servo motor through an electronic shaft system. The gearless structure reduces mechanical transmission components and provides precise control during high-speed printing.

High-Precision Printing

The double-wall central impression cylinder uses constant-temperature water circulation to maintain stable printing conditions and support high-precision printing.

Closed-Loop Web Tension Control

The unwinding system uses servo-driven central unwinding and closed-loop tension control. A lightweight floating roller provides automatic tension compensation to help maintain stable substrate movement.

Double-Station Non-Stop Unwinding

The double-station unwinding system supports continuous roll-to-roll production and reduces downtime during material changes.

Automatic EPC Web Guiding

An automatic EPC system is installed before the printing units to correct web edge position. Manual, automatic and center-return functions support accurate substrate alignment during production.

Intelligent Register Control

The machine supports electronic register adjustment with electric longitudinal and lateral positioning. Production parameters can be stored and recalled through the production menu and register memory functions.

Automatic Printing Pressure Control

The plate cylinder and anilox roller use independent servo-driven pressure adjustment. Pressure positions can be stored and recalled, while automatic pressure compensation helps maintain stable printing as production speed changes.

Sleeve Printing System

Sleeve-type plate and anilox roller structures allow fast cylinder changes and reduce job setup time. The cantilever-style structure provides convenient access for operators during sleeve replacement.

Chamber Doctor Blade Ink Supply

The enclosed chamber doctor blade system provides controlled ink transfer and helps reduce solvent evaporation. The pneumatic diaphragm pump supplies ink to the printing units, while automatic viscosity control is available as an option.

Centralized Hot Air Drying

The post-printing drying section uses centralized hot air drying with continuous temperature control. Variable-frequency fan control adjusts airflow according to production requirements, while secondary air return helps reduce energy consumption.

How It Works

From Unwinding to Rewinding

01. Double-Station Unwinding

Continuously feeds the substrate into the press and enables fast roll changes with minimal downtime.

02. Web Tension Control

Maintains stable and precise web tension to prevent wrinkles, stretching, and material deformation.

03. EPC Web Guiding

Automatically corrects web position to keep the substrate accurately aligned throughout the printing process.

04. Flexographic Printing

Independent servo drives precisely control each printing unit for accurate registration, stable color performance, and high-speed printing.

05. Centralized Drying

Rapidly dries the printed ink to prevent smearing and ensure consistent print quality between colors.

06. Cooling

Reduces the web temperature after drying, helping stabilize the printed material before rewinding.

07. Rewinding

Precisely winds the finished web into uniform, neat rolls for easy handling, storage, and further processing.
