Technical Data

Process Workflow

1. Feeding: PP/PE raw material pellets are loaded into the hopper and fed into the extruder barrel.
2. Extrusion: Material is melted under controlled temperature zones and shaped into a continuous tube via a precision die.
3. Cooling: The extruded tube passes through a water bath for rapid solidification and dimensional stability.
4. Sizing & Calibration: A vacuum calibration unit ensures consistent outer diameter and wall thickness.
5. Printing (Optional): Patterns or brand logos are applied using a rotary inkjet printing system.
6. Cutting: High-speed blades slice the continuous tube into precise lengths as set on the control panel.
7. Quality Inspection: Vision sensors automatically detect and reject out-of-tolerance straws.
8. Packaging: Finished straws are automatically counted and packed into bags or boxes for delivery.

Frequently Asked Questions

What materials can the SUHUI drinking straw making machine process?

The SUHUI drinking straw making machine is compatible with PP (polypropylene), PE (polyethylene), PLA (polylactic acid), and other biodegradable polymers. Material changeover is supported through parameter adjustments on the touchscreen PLC control panel, allowing manufacturers to switch between conventional and biodegradable straw production.

What straw diameter and length range does the machine support?

The machine supports straw diameters from φ1 mm to φ14 mm and straw lengths from 3 mm to 1,000 mm. Diameter and length parameters are set via the PLC control panel, allowing rapid changeover between different straw specifications without mechanical tooling changes.

What is the production output speed of the drinking straw making machine?

The machine delivers line speeds exceeding 250 m/min, producing up to 800 straws per minute depending on straw diameter and length settings. Three standard models (JH01-245, JH01-250, JH01-255) offer output capacities of more than 25 kg/h, 35 kg/h, and 45 kg/h respectively, scaling to match different production volume requirements.

How does the machine ensure consistent straw quality and dimensions?

Straw quality is maintained through a vacuum calibration unit that controls outer diameter and wall thickness consistency, a water bath cooling system that ensures dimensional stability, high-speed precision blades that cut straws to ±0.2 mm length tolerance, and integrated vision sensors that automatically detect and reject out-of-tolerance straws before packaging.

What is the temperature control configuration of the extrusion system?

The extruder barrel uses an 8-zone independent temperature control system that precisely manages melt temperature at each stage of the extrusion process. Inverter-controlled servo motors regulate screw speed, while zone-by-zone temperature control ensures consistent melt flow and uniform straw wall thickness across the full production run.

Is the drinking straw making machine suitable for small and medium-scale factories?

Yes. The SUHUI drinking straw making machine features a compact, optimized layout designed to fit within small to medium-scale production facilities. Its modular design supports easy maintenance and quick changeover between straw specifications, minimizing production downtime. The machine’s touchscreen PLC interface reduces the need for specialized operator training.
