The stable operation of non-woven bag making machines for spunbond non woven fabric requires a combination of standardized operation, regular maintenance, fault prevention, and environmental management measures. The following are the key points and specific implementation methods:
Daily maintenance and inspection
Lubrication and fastening of mechanical components
Regularly add lubricating oil to key parts such as gears, bearings, and guide rails to reduce wear (recommended once a month).Check all screws and nuts for looseness, especially the transmission system and cutting device, to avoid accuracy deviation caused by vibration.
Electrical system inspection
Ensure stable power supply voltage (such as 380V three-phase electricity), equipped with a voltage regulator to prevent voltage fluctuations from damaging the servo motor or controller .Clean the dust inside the electrical control box, check if the wiring terminals are loose, and prevent short circuits or poor contacts.
Key component status monitoring
Blade maintenance: Check the sharpness of the blade, replace worn blades in a timely manner (such as once a month), and prevent uneven cutting or burrs.Heat sealing system: Regularly clean the residue on the surface of the sealing blade, adjust the temperature (usually set at 120-200 ℃ according to the material thickness) and pressure to ensure a firm seal.
Regularly inspect equipment
Non woven bag making machine is a high-speed equipment, and long-term production process can cause wear and fatigue, which can easily lead to equipment failure. Therefore, it is necessary to regularly check the status of the equipment. Check the various components of the equipment, such as the transmission system, feeding system, heating system, electrical system, etc., to ensure stable operation of the equipment.
Maintain appropriate temperature
Temperature is an important factor affecting the production of non-woven bag making machines. Before production, sufficient time should be reserved for the equipment to preheat at high temperatures to ensure normal operation. During the production process, it is important to ensure that the equipment maintains a stable temperature and not to neglect the temperature status of the equipment in order to improve production efficiency.
Adjust equipment parameters based on bag type
The size, thickness, shape, and other parameters of non-woven bag making machines are required for the production of bags. Therefore, when changing the bag specifications and thickness, the equipment parameters should be adjusted according to the bag type to ensure that the quality of the produced bags meets the requirements.
Standardize operational procedures
Power on preparation
Preheat the barrel and mold to the process temperature (such as 180 ℃), hold for more than 20 minutes to ensure uniform temperature and avoid uneven material thermal shrinkage.Check that the safety door and emergency stop button are functioning properly to prevent accidents caused by misoperation.
Operation Monitoring
Use a photoelectric eye tracking system to calibrate the cursor position, ensuring that the bag length error is ≤ ± 1mm, and adjust the reflection/transmission mode and polarity setting .Real time monitoring of tension control system to avoid bag deviation or tearing caused by inconsistent film elasticity.
Shutdown processing
Turn off the heating system before shutdown to avoid damage to materials or equipment caused by residual heat.Clean up residual materials in the silo to prevent blockage or moisture from affecting the next production .
Common Fault Prevention and Handling
Bag length deviation
Reason: Inaccurate tracking of the electric eye, diameter error of the rubber roller, or controller malfunction.Solution: Re calibrate the photoelectric eye (choose scanning or fixed length positioning mode), replace the worn rubber roller or controller .
Poor sealing or glue leakage
Reason: Insufficient sealing temperature, uneven pressure, or damaged thermocouple.Solution: Adjust the temperature to above the melting point of the material, check the circuit connections, and replace the electric heating plate or thermocouple if necessary.
Frequent shutdown of equipment
Reason: The host speed is too fast or the voltage is unstable.Solution: Reduce the processing speed to the rated range of the equipment (such as 80% load) and install a voltage regulator device .
Environment and Data Management
temperature and humidity control
The workshop maintains a constant temperature (20-25 ℃) and humidity (50% -60%) to prevent non-woven fabrics from affecting dimensional accuracy due to moisture absorption, expansion, or contraction.
Data recording and analysis
Record the parameters of each production (such as temperature, speed, tension), establish a database for optimizing processes and quickly troubleshooting .
Operator training
Regularly train operators to familiarize themselves with equipment structure, common fault handling, and safety regulations (such as prohibiting manual cleaning of nozzle rubber heads).
Long term maintenance plan
Regularly clean equipment
Regardless of the type of equipment, regular cleaning and maintenance are necessary to ensure its proper functioning. For non-woven bag making machines, it is even more important to keep the equipment clean to avoid damage to equipment components and structures caused by dust, oil stains, etc.
Monthly maintenance: Thoroughly clean the inside and outside of the equipment, check the tightness of the drive belt, and lubricate all moving parts.
Annual maintenance: replace aging seals and bearings, calibrate sensor accuracy, upgrade control system software .
Summary
The normal operation of non-woven bag making machine requires regular inspection of equipment status, maintenance of appropriate temperature, adjustment of equipment parameters according to bag types, and regular cleaning of equipment. By standardizing operations, regular maintenance, timely troubleshooting, and environmental control, the operational stability and lifespan of non-woven bag making machines can be significantly improved. If encountering complex problems (such as servo system failures), it is recommended to contact professional technicians for handling. Only in this way can the non-woven bag making machine ensure long-term stable operation and produce high-quality non-woven bags.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
