Come utilizzare la macchina per la produzione di tubi di carta NRC150B

1. Place the NRC150B macchina per la produzione di tubi di carta according to our layout drawing.

   

2. Install the prepared raw paper rolls onto the paper stand, and pour the required glue into the glue tray on the glue stand.
3. Start the paper tube machine and the air compressor, keeping the machine running at low speed.
4. Lead the base paper through the base paper stand; it will naturally wrap around the mold as the macchina runs.
5. Guide the raw paper through the glue and the glue scraper, then feed it into the machine to wrap over the base paper. Repeat the above steps for the remaining layers of paper.

Common Faults & Solutions for how to operate NRC150B Paper Tube Making Machine

1. Paper tube out-of-round / deformed

• Causes: Uneven glue, uneven paper tension, mold worn, unstable speed.
• Solutions: Adjust glue amount & scraper; balance paper tension; replace mold; stabilize running speed.

2. Glue uneven / too thick or too thin

• Causes: Glue tray level off, scraper worn, glue too thick/too thin.
• Solutions: Level glue tray; replace scraper; adjust glue concentration.

3. Paper breaks frequently

• Causes: Tension too high, paper edge damaged, paper damp, speed too fast,the angle degree wrong.
• Solutions: Reduce tension; use good paper; dry paper; lower speed temporarily,adjust the angle degree of paper layer.

4. Tube length inaccurate

• Causes: Cutting knife dull, positioning error, speed fluctuation.
• Solutions: Sharpen or replace knife; recalibrate length; check inverter.

5. Tube delaminates / layers separate

• Causes: Insufficient glue, low temperature, insufficient wrapping pressure.
• Solutions: Increase glue; preheat glue/paper; adjust pressure roller.

6. Machine noisy / shaking

• Causes: Loose screws, bearing damaged, belt misaligned.
• Solutions: Tighten parts; replace bearing; adjust belt tension.

7. Air pressure insufficient (pneumatic models)

• Causes: Air compressor low, air leak, filter blocked.
• Solutions: Check compressor; fix leaks; clean air filter.
