High Speed Rotogravure Printing Machine consists of an automatic unwinding system, a tension control system, 1 to 10 printing units, an air drying module, an automatic roll changing device, an electronic control system and a registration detection module. The machine body adopts a modular structure + anti-static stainless steel machine cover. It is an industrial-grade high-efficiency printing equipment designed for flexible materials such as PE breathable film and cast film

1. Ultra-high-speed performance: greatly improved production efficiency

The high-speed gravure printing press boasts a maximum printing speed of 400m/min, significantly exceeding the 180-250m/min of traditional equipment. This significantly increases output per unit time while maintaining stable pattern quality, meeting mass production needs. The press supports printing on ultra-wide webs up to 2500mm at speeds of up to 150m/min, making it suitable for printing on large rolls such as packaging film.

2. Multi-ink compatibility: free switching of water-based inks

The system supports dual-channel ink paths for water-based inks and solvent inks, is equipped with constant temperature heating and anti-settling stirring devices, supports environmentally friendly low-VOC inks (compliant with EU RoHS standards), and supports fast ink path switching functions, with a switching time of less than 15 minutes to meet the needs of different orders.

3. Low tension control: suitable for light and thin materials

The High Speed Rotogravure Printing Machine adopts a constant pressure closed-loop tension control system, and the unwinding tension is controlled as low as 2.5N~3.5N, which effectively prevents ultra-thin breathable films and PE films below 12g/㎡ from wrinkling or tearing due to uneven force, thereby improving the yield rate and printing flatness.

4. Accurate overprinting: automatic positioning, error ≤±0.1mm

The high-precision servo registration system is equipped with a fixed-length detection device for printed patterns to automatically identify overprint marks and make dynamic adjustments. The overprint error is controlled within ±0.1mm, which is suitable for high-precision process requirements such as multi-color patterns and reverse positioning printing.

5. Intelligent drying system: air energy-saving drying

The standard air energy hot air drying system supports fast drying in energy-saving mode. Each printing unit is equipped with independent air ducts and temperature control, and the hot air temperature range is adjustable from 45°C to 85°C, which effectively avoids ink residue, transfer or blurred patterns.

6. One-button automatic roll change: 30% efficiency improvement

The High Speed Rotogravure Printing Machine is equipped with automatic splicing and switching functions, and the maximum unwinding/rewinding diameter is Φ800mm. The roll change time is controlled within 10~15 seconds, which improves the roll change efficiency, reduces the intensity of manual work, and improves the comprehensive utilization rate of the equipment.

7. Less material waste and more convenient operation

By optimizing the film material unfolding path, automatic ink delivery, online cutting and other devices, the film head and tail waste is controlled within 0.8%. At the same time, it is equipped with a centralized touch screen control system with clear operation logic, which is convenient for novices to get started quickly.

1. Baby diaper printing factory: Hengan Hengan International

Hengan Group uses the model for PE cast film pattern printing at its Quanzhou production base, which is used for the outer packaging film of baby diapers. It uses environmentally friendly ink for 8-color overprinting, with a maximum production speed of 380m/min, which effectively supports its monthly production capacity layout of 10 million.

2. Adult care product manufacturer: Daio Paper

Daio uses the High Speed Rotogravure Printing Machine equipment to print brand icons and batch numbers on adult urine pad bottom films in its local factory in Japan. Using a dual-channel ink system, the switching time is shortened to 10 minutes, supporting high-frequency order change operation mode.

3. Pet pad packaging film factory: Uni-Charm PetCare

Uni-Charm's pet products factory uses the High Speed Rotogravure Printing Machine for customized pattern printing on PET bottom films. The printed patterns are bright in color, use environmentally friendly inks, and have high pattern line accuracy, with errors controlled within the range of ±0.08mm.

4. Food packaging company: Amcor

Amcor uses High Speed Rotogravure Printing Machine for printing PE/PET multi-layer film food packaging bags to support wide-format bag making needs. The ink is food-grade solvent ink, the equipment achieves all-weather continuous production, and is equipped with an online pattern recognition and correction system.

5. Nonwoven fabric printing factory: First Quality

First Quality purchased High Speed Rotogravure Printing Machine model printing machine to print NWF nonwoven fabric materials for inner layer pattern decoration of baby and adult care products. The nonwoven fabric tension control is precise, the equipment runs stably, and the pattern alignment is free of ghosting.

1. Regular cleaning of the roller and the embossing roller

After each shift, the ink layer on the surface of the roller and the embossing roller should be thoroughly cleaned with a non-corrosive cleaning fluid to prevent the ink from drying up. Check the axis once a week for wear and deflection, and keep its circular runout ≤0.02mm.

2. Tension system calibration and sensor maintenance

It is recommended to conduct joint adjustment tests between the tension sensor and the PLC closed-loop system every week to ensure that the tension curve of each section is stable. When changing different substrates, the initial tension value of unwinding/rewinding should be reset, and the tension curve should be recorded for the next call.

3. Dust removal and temperature control detection of the drying system

The air-energy drying module needs to be cleaned once every 500 hours of operation, and the filter element should be cleaned with compressed air. The hot air thermostat is calibrated once a month to ensure that the error between the output air temperature and the set temperature is controlled within ±2°C.

4. Flushing and maintenance of the ink system

It is recommended to perform a weekly cycle flushing of the ink pump, ink tank and ink delivery hose, using the specified ink cleaning agent. If the shutdown exceeds 24 hours, the ink system should be emptied and sealed with inert gas to prevent ink precipitation or clogging.

5. Maintenance of automatic roll-changing knives and sensors

The pneumatic cutters in the rewinding and unwinding area should be kept sharp, and the blades should be replaced after every 50,000 meters of film material is processed; the automatic splicing sensor eye should be wiped clean every day to avoid roll-changing errors caused by dust obstruction, and ensure that the splicing accuracy rate is ≥98%.
