1. Product Overview
Il Automatico Tubo di carta a spirale del diametro interno di 500mm che fa la macchina (Four Heads PLC Control), manufactured by MACCHINA NRC (Qingdao New RiChuan Precision Machine Co.,Ltd), is a state-of-the-art industrial paper processing machine designed for high-volume, high-precision production of spiral-wound paper tubes.
It is High-efficiency, fully automatic equipment for producing large-diameter spiral paper tubes with precision PLC control.
It features a four-head winding system and advanced PLC (Programmable Logic Controller) with a touchscreen HMI, enabling fully automatic operation from paper feeding, gluing, winding, to precise cutting and final tube discharge.
This machine is engineered to produce paper tubes with an inner diameter ranging from 50mm up to 500mm, making it ideal for manufacturing large cores used in textiles, plastics, films, paper mills, construction, and packaging industries. The four-head design significantly boosts production efficiency while ensuring stable winding and uniform tube quality.
2. Working Principle of 500mm Inner Diameter Tubo di carta a spirale che fa macchina
The machine operates on the spiral winding principle:
- Unwinding & Tension Control: Multiple kraft paper rolls are loaded onto motorized stands, with constant tension control to ensure smooth paper feeding.
- Gluing System: Paper strips pass through an automatic gluing unit (single or double-sided) that applies adhesive evenly.
- Four-Head Winding: The glued paper strips are spirally wound simultaneously around a rotating mandrel by four synchronized winding heads. The multi-head design ensures balanced force distribution, stable operation, and higher speed.
- Automatic Cutting: An infrared sensor precisely measures the tube length. A servo-driven circular blade cuts the moving tube accurately without stopping the production line.
- Discharge & Collection: Finished paper tubes are automatically discharged and collected, completing the fully automated production cycle.
