Hot stamping foil slitting machine operation guide: avoid common slitting problems

Preparation before operation

1. Check the material: Make sure that the gold foil coil is free of creases and pollution, and the edge of the coil is neat

2. Equipment inspection: confirm the sharpness of the slitting blade and check whether the air pressure system is normal

3. Environmental control: keep the working environment clean, with appropriate temperature and humidity (recommended temperature 20-25°C, humidity 40-60%)

Common problems and solutions

1. Burr/irregular edges

• Possible cause: Blade passivation or improper installation

• Solution:

◦ Replace or sharpen the blade

◦ Adjust blade pressure (0.2-0.3MPa recommended)

◦ Check the tension of the gold foil roll (keep it uniform and moderate)

2. The slitting size is not accurate

• Possible causes: Loose mechanical drivetrain or faulty encoder

• Solution:

◦ Calibrate the slitting size setting

◦ Inspect and tighten transmission components

◦ Clean the encoder or contact a technician for service

3. The material is wrinkled

• Possible causes: uneven tension or unbalanced guide rollers

• Solution:

◦ Adjust the unwinding and rewinding tension

◦ Check the parallelism and levelness of all guide rollers

◦ Reduced slitting speed (especially thin gold leaf)

4. Slitting surface adhesion

• Possible causes: Static build-up or high temperature

• Solution:

◦ Install the static eliminator

◦ Reduce the temperature of the workshop

◦ Appropriate reduction of winding pressure

Routine maintenance recommendations

1. Clean the blades and guide rollers every 8 hours

2. Inspect the air system and transmission components weekly

3. Fully calibrate the accuracy of the equipment every month

4. Change the lubricating oil and filters quarterly

Safety Precautions

• Wear protective gloves and goggles when operating

• It is forbidden to touch moving parts with your hands while the equipment is running

• Press the E-STOP button immediately in case of emergency

• Inspect electrical safety devices regularly

Following these guidelines can significantly reduce slitting problems and improve production efficiency and product quality.
