High Speed Automatic Industrial Paper Tube Machine

1. What is an Auto Spiral Perforated Tube Rolling Machine?

It is a sophisticated, automated industrial machine designed to produce long, continuous tubes with perforated patterns from a coiled metal strip. The process integrates two key functions:

1. Spiral Forming & Welding: It forms a flat strip into a continuous spiral (helical) tube and welds the overlapping edges.

2. Perforation: It punches a precise pattern of holes (perforations) into the metal strip before or during the tube-forming process.

2. How It Works (Typical Process Flow)

1. Decoiling & Straightening: A coiled metal strip (stainless steel, carbon steel, aluminum, etc.) is loaded and automatically fed into a straightening unit.

2. Perforation (In-line): The straightened strip passes through a high-precision servo-driven punching unit. This unit, using a custom-designed punch and die, stamps the desired hole pattern (round, square, slot, decorative, etc.) onto the strip.

3. Forming: The perforated strip is then progressively formed by a series of rolls. The edges are curled to create the helical lock-seam or prepared for welding.

4. Welding: The overlapping spiral seams are welded together using TIG (for high-quality, oxidation-free welds) or HF (High-Frequency) contact welding (for high speed). This creates a strong, continuous tube.

5. Sizing & Cutting: The tube passes through sizing rolls to achieve perfect roundness and diameter. Finally, an automated flying cut-off saw or cutter cuts the tube to pre-set lengths without stopping the production line.

6. Control & Collection: The entire process is monitored by a PLC and HMI (Human-Machine Interface). Finished tubes are collected on a rack or conveyor.

3. Key Components of the Machine

• Uncoiler & Straightener: Holds and feeds the master coil.

• Servo Punching Unit: The heart of perforation, with a heavy-duty press, punch, die, and servo for synchronization.

• Forming Station: A series of hardened steel rolls arranged in a cage frame to gradually shape the strip.

• Welding System: TIG or HF welding apparatus with wire feeder (if needed).

• Sizing Station: Precision rolls to calibrate the tube diameter.

• Flying Cut-Off Unit: Servo-driven saw or cutter.

• PLC Control Cabinet & HMI: For automated operation and parameter setting.

• Exit Conveyor / Racking System.

4. Advantages & Features

• High Efficiency: Produces finished perforated tubes in a single, continuous automated process.

• Design Flexibility: Hole pattern, tube diameter (from ~20mm to over 1000mm), material thickness (typically 0.5mm to 4.0mm), and pitch are easily adjustable.

• Consistent Quality: Automation ensures uniform perforation and weld quality along the entire tube length.

• Material Savings: Uses coiled strip, minimizing waste compared to perforating pre-made tubes.

• Long Lengths: Can produce tubes significantly longer than typical mill lengths.

  
  

5. FAQs for Automatic Paper Tube Making Machine

Q1: What types of paper tubes can an automatic paper tube making machine produce?

A1: This automatic equipment manufactures spiral wound paper cores and paper tubes for multiple industries. Output includes packaging paper cores, tape core tubes, textile winding tubes, film and foil cores, as well as kraft cardboard industrial paper tubes. It supports production for both thin-wall light duty tubes and heavyduty highstrength paper cores according to production settings.

Q2: What raw paper materials are compatible with the automatic paper tube making machine?

A2: It works with kraft paper, corrugated laminated paper, composite paper strips and recycled paper. Operators can use different paper grammages to adjust final tube strength. Multiplelayer paper feeding design allows stacking different paper stocks to reinforce tube wall for heavyload application scenarios.

Q3: How accurate is the tube size on an automatic paper tube making machine?

A3: Driven by servo motor and precise cutting unit, inner diameter, wall thickness and cutting length are controllable. Length tolerance stays within ±0.5 mm. The finished tubes keep good roundness without deformation. All dimension parameters can be quickly modified on the PLC touchscreen for fast order switching.

Q4: How much labor and workshop space does an automatic paper tube making machine require?

A4: Fully automatic models greatly cut manual work. Only 1-2 operators per shift are needed for material feeding and finished tube collection. Standard unit requires around 80-120 m² workshop area. Customers can select single-head or multi-head configurations based on target daily output volume.

Q5: What technical and aftersales support do overseas clients receive from NRC Machinery?

A5: Every automatic paper tube making machine includes factory warranty, English operation manuals and maintenance video tutorials. Lifelong remote technical support and online troubleshooting are provided. On-site installation and staff training are available as optional services.
