Automated Offset Printing Press Blanket Cleaning Machine Stable

The automatic blanket washing system is a dedicated automated cleaning device designed for offset printing presses. Through a combination of pre-wet cleaning cloth/brush, pneumatic/electric drive and PLC intelligent control, it can quickly clean ink, paper lint, paper powder and impurities on the blanket surface with one click while the printing press is running without stopping.

Integrating functions such as automatic cleaning cloth conveying, pre-wetting, ink scraping, waste liquid recovery and fault alarm, the equipment is compatible with mainstream offset printing presses such as Heidelberg, Roland, Komori and Mitsubishi, and can also be customized for UV printing presses. Compared with manual cleaning, each cleaning only takes 1–2 minutes, which greatly improves printing efficiency, reduces labor costs, decreases VOC emissions, extends the service life of blankets and ensures the color consistency of printed products.

• Low-VOC/zero-VOC cleaning agent with a flash point ＞250℃, complying with environmental protection standards.
• High-efficiency utilization of cleaning cloth, solvent recycling, single use reduced to 30–50ml, solid waste reduced by more than 50%.
• Water-saving design, self-equipped water tank + micro-mist spraying, low consumption of purified water.

4. Strong Adaptability, Stable and Durable
• Aviation aluminum/stainless steel body, lightweight, corrosion-resistant and long service life.
• Compatible with mainstream offset printing presses, installed according to original factory hole positions without modifying the press body.
• Imported pneumatic/electrical components, low failure rate and simple maintenance.

5. Excellent Cleaning Effect
• Micron-level cleaning, residue ≤0.5mg/cm², one-time qualification rate of printed products reaches 98.6%.
• No damage to the blanket, uniform inking, 40%+ saving of makeready paper, and high color reproduction.

How to choose:

1. Match Printing Press Model
• Confirm the press model: Heidelberg, Roland, Komori, Mitsubishi, etc., and whether it is a UV printing press.
• Number of color groups: 4-color/6-color/8-color, requiring synchronous/independent cleaning.
• Installation conditions: original factory reserved hole positions/need for customized brackets, space dimensions.

2. Cleaning Technical Route
• Pre-wet cleaning cloth: mainstream type, uniform cleaning, no damage to the blanket, moderate consumable cost.
• Brush type: strong cleaning power, suitable for heavy dirt, need to replace brushes regularly.
• Water-based/solvent type: prioritize low-VOC/zero-VOC products that comply with GB 37822-2024.

3. Core Configuration and Performance
• Control system: PLC brand, touch screen, fault alarm, data recording.
• Drive mode: pneumatic (stable)/electric (low noise).
• Cleaning efficiency: single group time, multi-group synchronous capability.
• Environmental indicators: VOC emissions, solvent recovery rate, solid waste amount.

4. Consumables and After-Sales Service
• Cleaning cloth/brush: versatility, unit price, service life.
• Warranty: 1–3 years, lifetime maintenance, on-site service response time.
• Cases: usage effect of customers with the same press model/in the same industry.

5. Budget and Cost Performance
• Equipment price: domestic 20,000–80,000 yuan, imported 80,000–200,000 yuan.
• Comprehensive cost: equipment + consumables + maintenance + labor savings, payback period of 1–2 years.

How to use:

1. Installation and Commissioning
• Fix the main unit according to the reserved hole positions of the printing press, connect the air source/power supply/water tank.
• Install the cleaning cloth reel, thread the cloth to the recovery roller, and adjust the tension.
• Touch screen settings: cleaning time, liquid spray volume, color group selection, number of cycles.
• No-load test: normal cloth feeding, wetting, ink scraping and recovery, no cloth jamming or liquid leakage.

2. Daily Operation (One-Click Cleaning)
• The printing press is running normally, and the blanket needs cleaning due to dirt.
• Select the cleaning color group on the touch screen and start "Automatic Cleaning".
• The system automatically performs: pre-wetting → cleaning cloth attachment → roller rotation cleaning → waste cloth recovery → reset.
• After cleaning is completed, an automatic prompt will appear, and printing can continue.

3. Consumable Replacement
• When the cleaning cloth is used up: stop the machine, open the protective cover, take out the empty reel, install a new cloth, and re-thread the cloth.
• When the brush is worn: disassemble according to the instruction manual, replace with a brush of the same specification, and adjust the gap.

4. Maintenance
• Daily: Check the air source/power supply/water tank liquid level, clean impurities in the recovery tank.
• Weekly: Clean nozzles and ink scrapers, check cylinders/solenoid valves, and lubricate transmission parts.
• Monthly: Calibrate tension, check PLC programs, and back up parameters.
• Quarterly: Replace cleaning agent filter elements, detect VOC emissions, and conduct a full machine inspection.

5. Safety Precautions
• Do not open the protective cover during operation to prevent hand pinching and liquid spraying.
• Keep the cleaning agent away from fire sources; fire prevention is still required even if the flash point is ＞250℃.
• Stop the machine immediately when a fault alarm occurs, troubleshoot according to the prompt, and do not force operation.
• Train operators regularly and require them to work with certificates.
