What Are The Key Points For Daily Maintenance Of Bag Making Machines?

Daily maintenance of bagging machine is very important to ensure stable operation of bagging machine, prolong its service life and improve production efficiency. Daily maintenance points of the bagging machine include cleaning, lubrication, inspection, adjustment, safety, etc.:
1.Daily cleaning and Sanitation
Body and Workplace Cleanliness
Daily cleaning: Use dry cloth or soft-bristled brush to remove dust, oil and film debris from machine surfaces to prevent dust accumulation affecting heat dissipation or contaminated products.
Key areas: focus on cleaning the sealing area, slices, photoelectric sensor, conveyor belt, etc., to prevent clutter from interfering with machine operation.
Dust-proof: When not in production, cover the machine with a dust cover to reduce dust ingress.
Thermal Sealing System cleaning
Hot Seal Blade Wash: After daily production, wipe the surface of a hot Seal Blade with alcohol to remove melt residue (such as PE adhesive residue) and prevent loose seals or burrs.
Silicone Strip Inspection: Check for aging, cracking or deformation of silicone strip. If there is damage, it should be replaced in time to ensure uniform sealing pressure. Cutting System Cleaning
Cold Cutting Machine: Polishing the blade with greasestone or fine sandpaper to maintain it sharp and avoid cutting or burrs.
Moving Part Lubrication
Lubrication Cycle: Special lubricants (such as lithium based grease) are used weekly for moving parts such as chains, gears and bearings to reduce wear and noise.
Lubrication Points: Lubricate the unwinding shaft, guide rollers, conveyor belt rollers and cutting mechanism to prevent rust and blockage.
Anti-rust
Metal parts: Rust oil is commonly used in non-galvanized metal parts,such as frames and screws, especially in humid conditions.
Downtime maintenance: During extended downtime, thoroughly clean equipment, apply rust oil, and cover with a dust cover.
III. Inspection and replacement Key Components
Power System Inspection
Wiring Connections: Check daily for loose or damaged power cord and sensor cord to prevent short circuits or signal interference. Component Condition: check whether electrical components such as relays, contactors and switches are hot or have abnormal noise, and replace aging components in a timely manner.
Grounding protection: ensure good grounding of equipment to prevent static electricity and leakage.
Mechanical Component Inspection
Belts and chains: Check for wear and tear and loosening of conveyor belts and timing belts belts and adjust tension to an appropriate range.
Bearings and gears: Periodically check if bearings are fixed, check if gears are missing and replace if necessary.
Pneumatic Components: check cylinders and solenoid valves for leaks and air filters for any moisture or impurities.
Replacement Consumable Parts
Blade: Replace the blade periodically depending on production (e.g., every 1-2 weeks for cold blades and every 3-4 weeks for hot blades).
Silicone Strips: Replace every 3 to six months, or replace them in advance according to seal quality.
Photoelectric Sensors: cleaned every six months to test sensitivity and ensure accurate positioning.
IV. INTRODUCTION Introduction. calibration and adjustment of parameters
Temperature Control Calibration
Heat Sealing Temperature: weekly infrared thermometer is used to check whether the actual temperature of the heat seal blade is consistent with the set temperature. If the deviation exceeds ±5°C, calibrate the thermostat. Heating hose inspection: Check whether heating hose aging or short circuit, timely replacement of damaged parts.
Speed ​​and Tension Adjustment
Spindle Speed: adjust spindle speed according to material thickness to avoid seal loosening or high speed cutting deviation.
Tension control: Check the position of the float roller daily to ensure the film tension is stable and prevent stretching or wrinkling.
Seal pressure test
Pressure Adjustment: use pressure tester to check uniform sealing pressure and adjust cylinder or spring pressure to the recommended material value of 0.2-0.3 MPa for PE bags).
V. Safe Operation and Protection
Security Inspections
Emergency shutdown button: The emergency shutdown button is tested daily to ensure a timely response and can be turned off immediately in an emergency.
Shielding: Check the protection of cut and heated areas to ensure they are intact and to protect operators from hazardous areas.
Sensors: Check that the light screen is working properly to prevent people or foreign objects from entering hazardous areas.
Operational standards training
New employee training: Ensure operators are familiar with equipment start-up, shutdown, debugging, and emergency response procedures. Prohibition of operation: It is prohibited to clean blades, adjust heat seal temperature and touch moving parts during operation of equipment.
Personal Protective Equipment
Protective equipment: Operators are required to wear cutting gloves, goggles and dust masks to reduce the risk of accidental injury.
VI. INTRODUCTION INTRODUCTION INTRODUCTION Maintenance Records and plans
Daily Maintenance Records
Content: including cleaning times, lubrication areas, replacement wear site, fault detection and solution.
Data analysis: prepare preventive maintenance plan in advance by recording and analyzing equipment failure frequency.
Regular Maintenance Programme
Weekly maintenance: focus on lubrication, electrical connections and safety devices.
Monthly maintenance: maintenance of mechanical components, replacement of worn parts, calibration parameters.
Annual maintenance: Remove deep cleaning equipment and replace aging circuits and seals.
VII. Environmental and Storage Management
Working Environment Requirements
Temperature and humidity control: workshop temperature stays between 20 and30 degrees Celsius, humidity ≤60%, preventing excessive humidity and overheating.
Ventilation: Ensure good ventilation around equipment to prevent the accumulation of heat sealed smoke. Spare Parts management
Common spare parts inventory: Store consumable parts such as cutting blades, silicone strips and photoelectric sensors to reduce downtime.
Spare parts expiration date: Check the storage status of spare parts regularly to avoid expiration or damage.
VIII. Quick fixes for common glitches
Loose seal: Check temperature, pressure and silicone strip condition, adjust parameters or replace parts.
Cutting bias: cleaning the blade, adjusting the cutting position, or replacing worn blades.
Unusual equipment noise: Stop checking chains, gears or bearings, lubricate or replace damaged parts.
Error sensor alarm: Clean sensor surface, adjust sensitivity, or replace faulty sensor.
Through the daily maintenance of the system, the cloth bag duster can achieve efficient and stable operation, reduce downtime, prolong the service life of equipment and guarantee the quality and production safety.
