Enclosed Doctor Blade and Automatic Ink Supply System

In terms of ink supply and printing execution, the machine is fitted with an enclosed doctor blade matched with an automatic ink supply system. Compared with the traditional open ink supply structure, the enclosed design can effectively prevent ink splashing, volatilization, and dust pollution, keep the production environment clean and tidy, and reduce water-based ink waste. The automatic ink supplier can stably and quantitatively supply ink according to the printing speed and pattern requirements, ensuring uniform ink thickness on the printing surface, making printed patterns delicate and layers clear, and greatly improving the overall printing grade.

Video Inspection System for Zero-Defect Quality Assurance

To guarantee zero-defect printing quality, the equipment is equipped with a professional video inspection system for real-time printing effect detection. During high-speed operation, the system can automatically identify various printing defects such as missing ink, blurred patterns, printing deviation, and ink spots, and feed back abnormal information in real time. Operators can adjust equipment parameters in a timely manner according to the detection results, effectively reduce the defective rate of finished products, save raw material costs, and improve production yield and product qualification rate.

Flexible Unwinding and Rewinding Configurations

In order to adapt to different production batches and material specifications, the machine supports three unwinding methods and three rewinding methods for flexible switching.

Machine Details

This diversified configuration can be adjusted according to material thickness, width, hardness, and production process requirements, realizing customized production of different orders. Meanwhile, the equipment is compatible with two types of anilox rollers for customers to choose from, including metal anilox rollers and ceramic anilox rollers. The standard configuration adopts high-precision chrome-plated steel anilox roller, which has excellent wear resistance, high structural stability, and long service life, and can maintain stable ink transfer accuracy after long-term high-frequency operation. In addition, the machine supports dual-side synchronous printing, which doubles the production efficiency compared with traditional single-side printing equipment, greatly shortens the production cycle and improves the factory's order delivery capacity.

Optimized Unwinding Unit for Stable Material Conveying

The unwinding unit of the equipment is professionally optimized for stable material conveying. It supports single unwinding and shaftless unwinding modes, which is convenient for rapid loading of different material rolls. Equipped with an automatic tension control system, it can dynamically adjust the material tension during the unwinding process to avoid material stretching, deformation, or loose winding. The pneumatic feeding method ensures smooth and fast material feeding, stable material flatness, and lays a solid foundation for high-precision subsequent printing.

Precision Traction Unit with Dual Positioning Design

The traction unit adopts a combined structure of rubber wheels and steel roller-to-roller traction, matched with pre-press traction and post-press traction dual positioning design. This dual-group traction structure can effectively clamp and convey materials, prevent material deviation and sliding during high-speed operation, and ensure the synchronization of material conveying speed and printing speed. The stable traction system is the core guarantee for consistent printing registration accuracy in long-time continuous production.

Core Printing Unit with High-Precision Configurations

In the core printing unit, the equipment integrates multiple high-precision configurations to achieve ultra-high printing stability. It is equipped with an automatic web guide system to correct material deviation in real time, and adopts ultrasonic and servo motor combined feeding deviation correction technology, with sensitive response and high correction accuracy. The whole machine is driven by a synchronous belt, which features stable transmission, low noise, and no speed jitter. The rubber-plated roller is adjusted by hydraulic pressure, and the plate locking method also adopts hydraulic design, realizing precise and stable pressure regulation and plate fixing. Equipped with high-precision helical gears, the transmission operation is smoother and more durable. In terms of color registration accuracy, the equipment achieves a vertical registration stroke of ±15mm and a horizontal registration stroke of ±50mm, which can easily meet the high-precision printing requirements of fine patterns, text, and color overlay.

Independent Heating and Drying Unit

The independent heating and drying unit ensures fast drying of water-based ink and avoids ink smudging and pattern blurring. The electric heating mode is adopted with stable and uniform heating. The main oven is equipped with 11 heating tubes, and each color unit oven is equipped with 8 heating tubes, with a total heating power of 26kw. The oven length reaches 2.5 meters, matching the high-speed operation of the equipment. Equipped with a 2.2 kW main fan and 2.2kw color unit fan, the circulating air drying system can quickly take away water vapor, realize rapid and uniform drying of printed materials, and ensure clear and dry printing surface without sticking during rolling.

Reliable Electrical Components and Rewinding System

In terms of electrical components, the main motor adopts well-known brands such as SFC, Inovance, and Jiangke, with stable performance, strong power, low failure rate and durable service. The rewinding unit is equipped with friction rewinding mode, matched with low-friction cylinder and swing rod tension control system, which can stably control the rewinding tension to ensure neat and compact finished roll materials without loose rolling or edge warping.
