Step-by-Step Operational Workflow of Air Bubble Film Machinery

Operating a complex set of air bubble film machinery requires strict adherence to standard operating procedures. From pre-start preparation to final product winding, every step determines the final product's pass rate.

 

Step 1: Pre-operational Preparation

Before starting the bubble film machine, a comprehensive inspection must be performed.

Raw Material Inspection: Ensure LDPE granules are dry and free of impurities. If producing colored or antistatic films, the color masterbatch or additives must be mixed strictly according to the specified ratio.

System Inspection: Check that the electrical control cabinet wiring is secure and that the air system is unobstructed, especially the water cooling circulation system. Ensure a stable water flow, as this is crucial for bubble formation.

 

Step 2: Heating and Temperature Setting

Temperature control is the core of bubble film making machine operation.

Preheating Process: Based on the characteristics of the raw materials, set the heating temperature for each section on the PLC touchscreen. Preheating typically requires 1-2 hours; the machine can only be started after the temperature reaches the set value and stabilizes.

Temperature Fine-tuning: Operators must monitor the melt temperature in real time to prevent decomposition due to excessive heat or poor extrusion due to excessive cold.

 

Step 3: Extrusion and T-Die Adjustment

Once the temperature reaches the target, start the main motor to begin extrusion.

Melt Filtration: The filter inside the extruder traps impurities. When operating air bubble film machinery, observe the pressure gauge changes and replace the filter promptly to ensure stable melt pressure.

Thickness Control: Precisely adjust the bolts on the T-die to ensure consistent film thickness. This is a crucial indicator of a bubble film machine's precision and the operator's skill level.

 

Step 4: Bubble Forming and Cooling

This is the most technically demanding part of the bubble film making machine process.

Vacuum Adsorption: The molten film adheres to the surface of the forming roller and is drawn into the roller's small holes by vacuum suction to form bubbles. Pressure regulation of the vacuum pump is critical at this stage; insufficient pressure will result in incomplete bubble formation.

Water Cooling System: Cooling water circulates inside the forming roller. High-efficiency air bubble film machinery must be equipped with a large-capacity cooling circulation system to ensure rapid bubble setting during high-speed production.

 

Step 5: Trimming and Winding

The final step is to process the continuous film into rolls.

Online Slitting: Cutters on the side of the machine trim excess edge material. Ztech equipment typically features an online edge material recycling system that directly crushes and feeds waste back to the extruder.

Automatic Rewinding: After setting the rewind length, the bubble film machine automatically flips and cuts the roll. The accuracy of the tension control system determines the flatness and tightness of the finished roll.

Key Tips to Improve Efficiency and Product Quality

To achieve efficient operation of a bubble film machine, basic operation alone is insufficient; optimization of details is also necessary.

 

Optimizing the Matching of Screw Speed and Traction Speed

When operating air bubble film machinery, the extruder screw speed determines the output, while the traction roller speed determines the film thickness.

Synchronous Adjustment: Skilled operators utilize the synchronization function of the PLC system to proportionally increase the traction speed while increasing output, maintaining stable weight.

Stability First: Avoid frequent and drastic speed adjustments; a smooth production rhythm significantly reduces the scrap rate of the bubble film making machine.

 

Precise Control of Cooling Water Temperature Difference

The temperature of the cooling water directly affects the transparency and hardness of the bubbles.

 

Chiller Support

Equip the bubble film machine with a dedicated industrial chiller. Large temperature differences exist between summer and winter; maintaining a constant temperature for the cooling rollers through temperature control valves ensures consistent product quality across batches.

Regularly clean the die head and filter. Carbon buildup in the die head or a clogged filter is a major cause of black spots on the film.

 

Preventative maintenance

Don't wait until product defects appear before cleaning. Establishing a regular die head cleaning schedule not only improves the appearance of your air bubble film machinery but also reduces the load on the extruder.

 

 

Maintenance Tips for Long-Term Performance

Maintenance is key to ensuring the return on investment for your bubble film making machine. Good maintenance can keep the equipment running for over 10 years.

 

Lubrication of the transmission system

Bubble film machines have numerous gears, chains, and reducers.

Regular lubrication: Check the reducer oil level every 2000 hours of operation and change the gear oil if necessary.

Bearing inspection: Especially the bearings of the forming rollers and the extruder spindle; regularly lubricate them with grease to prevent wear-induced equipment vibration.

 

Dust prevention and tightening of the electrical system

Dust is inevitable in production workshops, which can threaten the electrical control system of air bubble film machinery.

Dust Cleaning: Regularly clean the dust inside the frequency converter and PLC cabinet monthly with compressed air to prevent poor heat dissipation or short circuits.

Screw Tightening: Long-term equipment vibration may cause wiring terminals to loosen. Regularly tightening all wiring terminals can effectively prevent unexplained shutdowns.

 

Protection of Critical Components

The forming roller and extrusion screw are core components of the bubble film making machine and are expensive.

Preventing Hard Objects from Entering: Metal detectors must be used during material feeding. Hard metal objects are strictly prohibited from entering the extruder to avoid scratching the screw or die.

Shutdown Protection: Before long-term shutdown, empty the residue from the barrel and apply anti-rust oil.
