paper corner protector machine equipment are key equipment for producing paper corner protectors, and their stable operation directly affects product quality and production efficiency.

1、 Daily inspection items

mechanical part

Transmission system: Check whether the chains, belts, and gears are loose, worn, or poorly lubricated.

Roller and mold: Confirm that the surface of the pressure roller and forming roller is clean and free of residual glue, and that the mold is not deformed or worn.

Fasteners: Check if bolts, nuts, etc. are loose, especially in areas with high vibration.

Bearings and guide rails: Whether lubrication is normal, whether there is any abnormal noise or overheating phenomenon.

electrical system

Motor and frequency converter: whether they run smoothly, whether there are any abnormal noises or heating.

Sensors and limit switches: Are photoelectric sensors and position sensors sensitive, and are limit switches reset properly.

Line safety: Check the cables of the paper corner protector machine for aging, damage, and reliable grounding.

Pneumatic/Hydraulic System (if applicable)

Air pressure/oil pressure: Whether the pressure is stable and whether there are leaks in the pipeline.

Cylinder/oil cylinder: whether the action is smooth, whether the seals are leaking air/oil.

Raw material and finished product quality

Paper roll supply: Whether the tension of the paper roll is uniform and the edges are aligned.
Glue system: Whether the glue spraying is uniform and whether the nozzle is blocked.

Finished product inspection: whether the size, angle, and adhesive strength of the corner protector meet the standards.

2、 Periodic inspection (weekly/monthly)
Deep Cleaning

Remove paper scraps and adhesive residue inside the paper corner protector production line to avoid blockage or corrosion.

Lubrication maintenance

Replace or supplement lubricating grease (such as bearings, guide rails).

Accuracy Calibration

Check whether the gap between the forming rollers and the position of the cutting blade are accurate.

Replacement of vulnerable parts

Check the wear and tear of cutting tools, molds, belts, etc., and replace them in a timely manner.

Regular inspections can reduce sudden shutdowns and extend the lifespan of paper corner protectors.
