Bảo trì hàng ngày máy đóng gói đứng VFFS: Chìa khóa cho hoạt động hiệu quả

VFFS (Vertical Form Fill Seal) packaging machines are essential equipment widely used in the food, pharmaceutical, and chemical industries. Their high efficiency and automation significantly enhance productivity. However, maintaining the stable operation of precision machinery requires regular and careful maintenance. This article explains the importance and detailed procedures for daily cleaning, lubrication, and periodic replacement of wear parts for VFFS machines, helping you ensure efficient, long-term performance.

1. Daily Cleaning: Keeping Equipment Clean

Daily cleaning is fundamental and critical in maintaining VFFS machines. Regular cleaning extends machine life and ensures product hygiene, especially in the food industry.

• Cleaning Essentials:

  • External Cleaning: At the end of each production day, use a clean, soft cloth to wipe machine surfaces, removing dust, residue, and oil. Stainless steel parts may be cleaned with food-grade detergents, rinsed thoroughly, and dried completely.
  • Cleaning Product Contact Parts: Components directly in contact with materials (e.g., hoppers, measuring devices like multihead weighers or auger fillers, formers, and sealing jaws) must be thoroughly cleaned. Initially, use compressed air to remove residues. Depending on the material, clean with warm water, food-grade detergents, or specialized solvents. Rinse and dry completely to avoid contamination or corrosion.
  • Forming Tube: Remove it from the machine for thorough cleaning. Use a soft brush and mild detergent to remove residue, rinse with water, and dry completely. (packstec.com)
  • Sealing Jaws: If dirty, remove the cutting knife first, then clean the sealing jaw surfaces with a damp cloth. (packstec.com)
  • Hopper: Empty the hopper and use a mild detergent with a soft brush to clean out product residues. Rinse and dry thoroughly.
  • Waste Removal: Regularly remove waste materials and packaging film debris from inside and around the machine to prevent blockage and operational issues.
  • Air System Cleaning: Periodically inspect and clean moisture and impurities from the air system, ensuring clean, dry air supply and preventing pneumatic component damage.

Precautions:

• Always disconnect the power supply before cleaning for safety.
• Avoid corrosive or abrasive cleaners to protect surfaces and components.
• Protect electrical components and sensors from water exposure during cleaning.

 

2. Lubrication: Ensuring Smooth Operation

Proper lubrication is crucial for the smooth and efficient operation of moving parts in VFFS machines. It reduces friction, minimizes wear, extends component life, and decreases downtime.

Lubrication Essentials:

• Identify Lubrication Points: Review the machine’s operation manual to identify all parts needing lubrication, such as gears, bearings, chains, rails, and cams.
• Select Appropriate Lubricants: Use the correct oil or grease. Food-grade lubricants are necessary for the food industry to ensure product safety.
• Lubrication Frequency: Follow the recommended lubrication schedules in the equipment manual, typically daily, weekly, monthly, or quarterly. Avoid excessive or insufficient lubrication.
• Lubrication Methods:
  • Manual Lubrication: Apply lubricants using an oil gun or brush.
  • Automatic Lubrication System: High-end machines might include automated lubrication systems. Regularly check lubricant levels and system conditions.

Precautions:

• Clean lubrication points thoroughly before application to avoid introducing contaminants.
• Use lubricant in moderation. Excessive lubrication may cause overflow and contamination of products or the environment.
• Regularly inspect lubricant quality, replacing any lubricant that becomes degraded or contaminated.

3. Post-Cleaning Procedures

• Reassembly: Ensure all parts are completely dry before reassembling the machine according to the manufacturer’s instructions. (lintyco.com)
• Reconnect Power and Air Supply: After reassembly, reconnect power and air sources. (lintyco.com)
• Test Run: Conduct an empty bag test to ensure all functions operate correctly before resuming regular production.
