HD1200 Sanitary napkin production machine

The HD1200 source records servo drive, HMI operation, tension control with a buffer, automatic web guiding, automatic counting and stacking, and safety devices. It also lists a 1,200 ppm design speed and 1,000 ppm stable working speed. These references help organize maintenance, but troubleshooting should be performed under the machine's approved safety procedure and with a known product recipe.

Begin with the symptom, not the component catalog

A disciplined fault-isolation sequence

1. Secure the condition.Follow lockout and the documented safety procedure before entering guarded areas.
2. Preserve evidence.Keep affected products, alarm history, recipe name and material-lot information.
3. Locate the first deviation.Trace upstream from the visible defect until the product or web returns to normal.
4. Change one cause at a time.Separate material, setting, sensor and mechanical checks so the correction is explainable.
5. Verify at controlled speed.Inspect the corrected function before returning to the contracted production condition.
6. Record the recovery.Save the action, parts used, resulting samples and approved recipe value.

Maintenance points organized by process risk

Material changes that can look like machine faults

The recorded inputs include topsheet nonwoven, fluff pulp, SAP, backsheet, back release paper, pouch film, easy tape, airlaid paper, construction glue and position glue. A change in roll width, surface treatment, tensile behavior, release force, film print mark or adhesive condition can create a new symptom without a mechanical failure. Compare the incoming material specification and lot with the approved FAT material before altering servo phase or web-guiding settings.

Maintenance FAQs

Service conclusion

Reliable maintenance on the HD1200 comes from preserving cause and effect. A fault history tied to product samples, material lots and exact corrections gives HAINA and the operating team a stronger basis for remote support, spare-part planning and future FAT comparison.
