With the surge in demand for e-commerce logistics and precision instrument transportation, air column bags have become a star product in the packaging field due to their excellent cushioning and protection performance. As the core equipment for air column bag production, the air column cushion bag making machine production line integrates the whole process of film forming, inflation and sealing, slitting and winding.
This article will disassemble the operation logic of this intelligent production line in detail for you, help buyers quickly grasp the key points of equipment operation, and achieve advancement from "start-up novice" to "production expert".
What does the air column cushion bag making machine consist of?
Before formal operation, it is necessary to establish a systematic understanding of each module of the production line:
*Film making unit: using multi-layer co-extrusion technology, PE/PA raw materials are extruded through the die head to form a cylindrical film
*Inflatable sealing unit: equipped with high-precision air pump and heat sealing device to achieve synchronous inflation and longitudinal sealing
*Slitting and rewinding system: slit wide films into different specifications according to needs (common width 20-100cm)
*Intelligent control center: PLC+touch screen combination, can preset more than 30 parameters such as pressure, temperature, speed, etc.
*Safety protection system: including triple protection mechanisms such as emergency stop button, overload protection, and leakage monitoring.
How to operate the air column cushion bag making machine correctly?
Step 1 Preparation before starting
*Check the stability of the three-phase power supply (voltage fluctuations must be controlled within ±5%)
*Confirm that the air source pressure reaches the standard value of 0.6-0.8MPa
*When installing PE coils, pay attention to distinguishing the AB surface (it is recommended to use the light transmission detection method)
Step 2 Parameter preset
*Set through the HMI human-machine interface:
*Temperature parameters: die area 195-210℃ heat sealing area 150-170℃
*Inflation pressure: 0.12-0.25MPa (adjusted according to film thickness)
*Production speed: It is recommended to set the initial setting to 15-20m/min, which can reach 35m/min after proficiency
Step 3 Start trial operation
*Start step by step in the order of "film making → film penetration → inflation → sealing → slitting"
Key observations:
*Film stretching uniformity (no light or dark stripes during light transmission)
*Air column fullness (diameter must be within ±2% of the preset value)
*Sealing line flatness (tested with a peel tester ≥3.5N/15mm)
Step 4 Quality monitoring
Hourly sampling inspection:
*Burst pressure (standard ≥35kPa)
*Sealing integrity (no continuous bubbles in immersion test)
*Dimension tolerance (length error ≤±1.5%, width ≤±1%)
Step 5 Abnormal handling
Common problem solutions:
| Fault phenomenon | Possible cause | Solution |
| Flat bubble | Insufficient air pressure/leakage | Check the air path sealing and adjust the boost valve |
| Seal cracking | Temperature offset/uneven pressure | Calibrate the parallelism of the heat sealing head and reset the temperature curve |
| Film wrinkles | Tension imbalance/guide roller offset | Adjust the unwinding tension to 15-20kg and correct the guide roller angle |
Step 6 Slitting and rewinding
*Set the slitting quantity according to the order requirements (the recommended maximum slitting number is ≤8 strips)
*Rewinding tension is controlled at 8-12kg (too large will cause deformation of the film roll)
*Use an electronic meter to ensure that the length error of each roll is less than 0.3%
Step 7 Shutdown maintenance
*Strictly implement the "cooling → power off → sewage discharge" process:
*Reducing the temperature of each heating zone to below 80°C
*Release the residual air pressure after cutting off the main power
*Clean the die head residue (it is recommended to use a copper scraper)
How to effectively improve the efficiency of the air column bag making machine?
Strategy 1: Raw material pretreatment
*PE particles need to be dried at 60℃ for 4 hours in an environment with humidity > 60%
*When adding 5%-8% recycled materials, the extrusion temperature should be increased by 3-5℃
Strategy 2: Intelligent parameter optimization
*Record production data through the MES system and establish parameter templates for products of different specifications:
*Small bubble bags (Φ15mm): high speed and low pressure mode (25m/min/0.15MPa)
*Atmospheric column bags (Φ35mm): medium speed and high pressure mode (18m/min/0.22MPa)
Strategy 3: Preventive maintenance
*Develop a three-level maintenance plan:
*Daily maintenance: clean guide rollers, check air pipe joints
*Weekly maintenance: calibrate temperature sensors, lubricate transmission chains
*Monthly maintenance: replace filter elements, test motor insulation resistance
Red line for safe operation: six regulations that must be followed
1.It is strictly forbidden to touch the heat-sealed parts in operation with bare hands (surface temperature ≥150℃)
2.Asbestos gloves must be worn when handling die head accumulation
3.The machine should be shut down immediately when the voltage fluctuation exceeds ±10%
4.The safety switch of the slitting machine needs to be locked when changing the tool
5.Check the grounding resistance value (≤4Ω) daily
6.Press the emergency stop button immediately when there is a sudden abnormal sound or burnt smell
After mastering these operating points, the production line can achieve a standard production capacity of 8000-12000 meters per day. It is recommended that new users record the equipment operation log every week for the first three months, and gradually explore the parameter combination that best suits their own production needs by analyzing key indicators such as temperature fluctuation curves and energy consumption data.
With a deeper understanding of the characteristics of the equipment, you will be able to give full play to the potential of this intelligent production line and gain a competitive advantage in the field of air column bag manufacturing.
