Secondary Ink Cartridge Assembly | Integrated Fluid Solution for Industrial Inkjet Ink Path

In the industrial inkjet mass production scenario, problems such as bubble interference, negative pressure fluctuations, and white ink sedimentation blockage have long-term impacts on the continuous and stable operation of the equipment. **KUNAG Kunag Fluid Control Systems (Shanghai) Co., Ltd. is deeply engaged in the field of precision fluid control. We have independently developed a complete set of ink supply modules, including secondary ink cartridge/tank assemblies, ink path dedicated solenoid valve integrated valve groups, and negative pressure matching components. The structure, valve components, and air path are designed in a coordinated and integrated manner to provide stable and reliable ink supply for UV, solvent, water-based, and white ink industrial inkjet equipment.
1、 Secondary ink cartridge/secondary ink tank assembly (core product)
KUNAG Kunag has a rich product line of secondary ink cartridges, covering single chamber, dual chamber, four chamber multi ink storage structures, dual connected ink tanks, and glass ink tank assemblies.
The product integrates a liquid level detection module, an anti shake plate, and a white ink specific anti settling structure, effectively alleviating pigment settling and reducing the risk of nozzle clogging;
Compatible with mainstream industrial nozzles such as Ricoh G5/G6, Seiko, Kyocera, etc., it is compatible with various media such as UV ink, solvent ink, water-based ink, white ink, etc., and can meet the ink supply needs of different printing scenarios such as UV flatbed machines, digital printing, OnePass line scanning equipment, etc.
2、 Ink road dedicated solenoid valve, integrated valve group
Different from the assembly solutions of externally purchased valve bodies on the market, KUNAG Kunag's matching solenoid valves and integrated valve groups are all independently developed, and ink cartridges and valve groups are synchronously developed and integrated for assembly.
The internal flow channel of the ink road has a higher matching degree, excellent sealing performance, and avoids the hidden dangers of ink leakage and ink leakage; The layout of the valve group can be customized according to the number of nozzle channels and equipment control logic, achieving independent on/off, cleaning, and circulation control of each ink channel, and adapting to high-speed continuous printing conditions.
3、 Negative pressure matching components
KUNAG Kunag synchronously provides negative pressure safety bottles, gas path stabilizing components, and liquid level sensor assemblies to build a complete gas-liquid collaborative system.
Stabilize the negative pressure range of the ink path and improve the problems of ink interruption, dripping, and flying caused by negative pressure fluctuations; Real time online monitoring of liquid level, supporting signal feedback and ink shortage warning, effectively protecting precision nozzles and reducing downtime and maintenance costs.
4、 Core advantages of the plan
✅  The white ink solution is mature and has a prominent market reputation**
Targeted solutions to the pain points of white ink pigment precipitation, pipeline powder accumulation, and nozzle blockage are the preferred ink path solutions for white ink UV and white ink digital printing equipment.
✅  Directly addressing the pain points of three major industries: sedimentation, bubbles, and negative pressure fluctuations**
The multi chamber structure achieves efficient bubble separation, the anti oscillation plate suppresses ink oscillation under high-speed working conditions, and the stabilizing component stabilizes negative pressure output, ensuring uninterrupted production for 7 × 24 hours.
✅  Integrated research and development within the same factory, with stronger system compatibility**
Ink cartridges, ink valves, and negative pressure components are developed in the same system, rather than simply combining scattered accessories. The overall debugging difficulty is lower, and the stability of the entire ink path system is stronger.
✅  Multi media and multi nozzle adaptation, supporting non-standard customization**
UV、 Solvent, water-based, white ink all medium coverage, compatible with mainstream industrial nozzles such as Ricoh, Seiko, Kyocera, etc., can be customized and developed according to the needs of equipment manufacturers.
5、 Application Fields
UV flatbed inkjet equipment, digital printing equipment, OnePass high-speed line scanning inkjet printing, packaging inkjet coding, building materials inkjet printing and other industrial inkjet equipment are fully equipped.
KUNAG Kunag can provide individual product supply and also undertake customized development of complete ink flow systems, cooperating with equipment manufacturers to iterate ink flow solutions synchronously, and assisting in stable and efficient production of printing equipment.
