Semi-Auto Pail Weight Filling Machine for Water Injection and Drying Prevention of Paint
Semi-Automatic Pail Weight Filling Machine for Water Injection and Drying Prevention in Paint
Overview:
The semi-automatic pail weight filling machine is designed for precise, controlled filling of paint or coatings into pails, with optional water injection to prevent drying and maintain product consistency. This system ensures accurate dosing, minimal waste, and contamination control while addressing the challenges of viscous, thixotropic, or moisture-sensitive materials. It is ideal for small to medium-scale production in industries like automotive, aerospace, and industrial coatings.
Key Features:
Weight-Based Filling:
High-Precision Load Cells: Ensures ±0.2% accuracy by stopping the fill cycle when the target weight is reached.
Programmable Batch Recipes: Quickly set and save fill weights for different pail sizes or paint formulations.
Drip-Free Nozzles: Prevents dripping or leakage during and after filling.
Water Injection System (Optional):
Proportioning Pumps: Automatically injects water or solvents into the paint at a preset ratio to maintain consistency.
Static Mixers: Ensure homogeneous blending of injected water with the base paint.
Purge Function: Cleans the water line to prevent clogging or contamination.
Drying Prevention:
Inert Gas Blanketing (Optional): Nitrogen or CO? purging creates an oxygen-free environment to prevent skinning or drying.
Heated Jackets (Optional): Maintains paint temperature to prevent thickening or solidification.
Sealed Filling Area: Minimizes exposure to air, reducing evaporation and contamination.
Paint Compatibility:
Viscous Fluid Handling: Gear pumps or piston diaphragm pumps handle high-viscosity (up to 10,000 cP) and thixotropic paints.
Corrosion-Resistant Materials: Stainless steel (304/316) construction with PTFE/FKM seals for chemical compatibility.
Filter Housing: Inline filters prevent contaminants from clogging nozzles.
User-Friendly Operation:
Touchscreen HMI: Intuitive interface for setting parameters, monitoring batches, and troubleshooting.
Foot Pedal Control: Hands-free start/stop for safe and efficient operation.
Manual Override: Allows manual adjustment during setup or maintenance.
Safety & Compliance:
ATEX/IECEx Certification: Explosion-proof design for hazardous environments (Zone 1/21 or Zone 2/22).
Static Grounding: Eliminates static buildup during filling.
Spill Containment: Drip trays or enclosed filling booths catch accidental spills.
Maintenance & Cleanliness:
Tool-Free Nozzle Removal: Simplifies cleaning and maintenance.
Self-Purging Function: Automatically cleans the nozzle after each cycle.
Quick-Change Parts: Interchangeable nozzles and hoses for different products.
Customization Options:
Multi-Lane Configuration: Add filling heads for higher throughput.
Labeling Integration (Optional): Apply barcodes, batch numbers, or expiration dates.
Pail Conveyor System (Optional): Automates container loading and unloading.
Compliance & Certifications:
CE Marking: Complies with EU safety and environmental standards.
ISO 9001 & 14001 Certified: Adherence to quality and environmental management systems.
GMP Compatible (Optional): For pharmaceutical or food-grade applications.
Applications:
Paint & Coatings: Filling waterborne, solvent-based, or UV-curable paints into pails.
Industrial Coatings: Packaging epoxy, polyurethane, or specialty coatings.
Automotive: Filling OEM or custom paint formulations for assembly lines.
Aerospace: Precision filling of high-viscosity or moisture-sensitive coatings.
Construction: Dispensing architectural coatings or sealants.
Operation Steps:
Container Loading: Empty pail is placed on the weighing platform (manually or via conveyor).
Nozzle Positioning: Telescopic or fixed nozzle extends into the pail to minimize splashing.
Filling: The machine fills the pail to the preset weight using load cells.
Water Injection (Optional): If enabled, water or solvent is injected and mixed into the paint.
Sealing & Capping: Operator manually applies a lid or cap (optional automated capping).
Container Removal: Filled pail is removed manually or transferred via conveyor.
Cleanup (Optional): Nozzle self-purges or undergoes manual cleaning.
Benefits:
Accuracy: Weight-based filling ensures precise dosing, reducing overfilling and material waste.
Consistency: Optional water injection maintains paint viscosity and prevents drying.
Safety: ATEX certification, drip-free nozzles, and static grounding ensure safe operation in hazardous environments.
Flexibility: Handles viscous, thixotropic, or moisture-sensitive paints with ease.
Efficiency: Semi-auto operation reduces labor costs while maintaining high throughput.
Environmental Impact: Drip-free technology and sealed filling minimize spills and emissions.
Low Maintenance: Tool-free cleaning and durable construction minimize downtime.
