Semi-Automatic Pail Weight Filling Machine for Water Injection & Drying Prevention in Paint

Overview:

The Semi-Auto Pail Filling Machine is designed for precise, efficient filling of water into paint pails while integrating drying prevention features to maintain paint integrity. It combines weight-based accuracy, splash-free operation, and optional automation for seamless water injection into 5–25L pails.

Key Features:

1. Precision Filling:

• Weight-Based Control: ±0.1% accuracy using load cells and HMI touchscreen calibration.

• Flow Rate Adjustment: Variable speed pumps for controlled water dosing.

• Anti-Splash Nozzle: Stainless steel, drip-free design to minimize contamination.

2. Drying Prevention Integration:

• Inert Gas Blanketing (Optional): Introduces nitrogen or CO? to create a protective layer, preventing oxidation and drying.

• Sealed Pail Lid: Compatible with sealed or vented lids; optional automatic capping for airtight closure.

• Humidity Control: Desiccant packs or moisture-absorbing lids (optional).

3. Safety & Compliance:

• ATEX/IECEx Certified: For safe operation in hazardous environments (paint fumes).

• Static Dissipation: Conductive materials and grounding systems to prevent sparks.

• Corrosion-Resistant Build: 304/316L stainless steel frame, PTFE seals, and chemical-resistant coatings.

4. Ease of Use:

• Semi-Auto Operation: Manual pail placement with foot pedal or HMI start.

• Quick Changeover: Tool-free nozzle swaps for different pail sizes (5–25L).

• HMI Touchscreen: Save recipes for varying water volumes and pail types.

5. Cleaning & Maintenance:

• CIP Compatibility: Clean-in-Place options with automated rinse cycles.

• Removable Drip Tray: Stainless steel tray for easy cleanup.

• Nozzle Purging: Automatic blowdown with air or solvent to prevent clogging.

6. Customization Options:

• Heaters/Stirrers: Keep paint at optimal temperature and consistency.

• Fumes Extraction: Integration with overhead arms or downdraft tables.

• Barcode Scanning: Track batches and ensure traceability.

Technical Specifications:

• Filling Range: 1–25 liters (adjustable in 0.1L increments).

• Accuracy: ±0.1% of target weight.

• Materials: 304/316L stainless steel, PTFE seals, FKM gaskets.

• Safety Certification: ATEX, IECEx, CE.

• Power Requirements: 220V/50Hz or 110V/60Hz (customizable).

• Environment Rating: IP65 (dust and water resistant).

Operation Steps:

1. Pail Placement: Manually position the empty paint pail under the filling nozzle.

2. Start Cycle: Initiate via foot pedal or HMI touchscreen.

3. Water Injection: The machine fills the pail to the preset weight, stopping automatically.

4. Inert Gas Blanketing (If Equipped): Optional nitrogen/CO? purge to protect the paint surface.

5. Capping (Optional): Seal the pail with an automated capping system.

6. Pail Removal: Manually remove the filled pail or use an optional conveyor.

7. Cleanup: Nozzle purges automatically to prevent cross-contamination.

Applications:

• Paint Manufacturing: Water injection into base coats, primers, or thinners.

• Coatings Production: Accurate dilution of high-viscosity coatings.

• Industrial Chemicals: Filling water into pails for other liquid formulations.

Benefits:

1. Precision & Consistency: Ensures exact water volumes to maintain paint viscosity and quality.

2. Drying Prevention: Inert gas blanketing and sealed lids protect paint from oxidation.

3. Safety: ATEX/IECEx compliance and static dissipation for hazardous environments.

4. Efficiency: Quick changeovers and semi-auto operation reduce labor time.

5. Customization: Tailored for specific pail sizes, water volumes, and drying prevention needs.

6. Low Maintenance: Robust design with CIP and removable components for easy cleaning.
