Maintenance covers daily checks, part care, and fault handling. Do the work on a schedule. This keeps the machine running and extends service life.
Daily checks and basic maintenance
Photoelectric sensor and reflector. Before startup each day, check the photoelectric sensor for damage. Check that the reflector is in the correct position and free of dust. If the reflector has shifted, align it with the sensor. If dust covers the surface, wipe it with a clean soft cloth. This keeps signal transmission stable.
Fasteners. Check screws and nuts for looseness. Tighten any loose fastener right away. If a screw or nut is missing, mark the location and tell a trained technician. Do not take the machine apart on your own, or you may damage parts.
Strap feed track. Check the feed track for debris, such as strap fragments and dust. Clean the track with compressed air or a soft brush. This keeps the strap moving and prevents jams or slip.
Lubrication and running checks
Crankshaft lubrication. Check the crankshaft for oil weekly. Use the dip and drip method. Dip a thin wooden stick in a small amount of lubricating oil and drip it slowly onto the shaft. Keep oil out of the strap feed track. Low oil increases crankshaft wear and can cause vibration or noise.
Abnormal conditions. If the machine makes unusual noise, vibrates too much, or gives off an odor, stop it and call a technician. Loose internal parts, worn bearings, or electrical faults can cause these signs. Running the machine can lead to more damage.
Strap quality and fit
Strap quality check. Before production, check that the strap specs are consistent. Avoid strap with uneven thickness, uneven width, or a rough surface. This kind of strap can fail to feed, fail to tighten, or jam, which lowers production efficiency.
Handling method: cut out the bad section. Run a test strap and adjust the tension knob until the result meets the standard. If a whole roll is poor, change to a new roll.
Feed problems. If the strap cannot enter the feed track or jams often, check two things. First, check whether the feed track has come loose. A missing nut can let the track shift. Second, check whether the strap size matches the machine. Width and thickness must meet the standard. Clear leftover strap fragments, then reset the track or change the strap.
Common fault fixes
No strap or missed strap.
Photoelectric sensor fault: check alignment between the sensor and reflector. Replace the sensor if it is damaged.
Heating iron temperature: set it to 300 C, within plus or minus 10 C. Too high can break the strap. Too low gives a weak seal.
Strap jam. Stop the machine. Remove the strap guard beside the feed track. Take out the jammed strap. Blow out leftover fragments and dust with compressed air. This helps prevent a second jam.
Maintenance schedule:
Daily: check the photoelectric sensor, fasteners, and feed track.
Weekly: lubricate the crankshaft and spot-check strap quality.
Monthly: clean the inside of the machine and check electrical connections.
Systematic maintenance lowers fault rate, extends service life, and keeps production continuous.
When a roller, guide, cutter, or other wear part reaches its limit, Hansheng Automation can machine a replacement from customer drawings. Our drawing-based service also covers filling machinery, tobacco packaging machinery, yacht components, and RC car components, along with non-standard parts for food, printing, and medical equipment. We handle single pieces and small batches.
