Consists of Qingdao Perfect Equipment CNC automatic paper square tube making machine
1) Paper Stand: The machine's "raw material reservoir," used to hold the rolls of base paper. It can be configured with multiple shafts to accommodate the required number of paper layers; some high-end models also feature automatic web guiding and tension control systems.
2) Gluing & Drying: A gluing mechanism (such as a glue pan or doctor blade) applies an even layer of adhesive to the paper; some machines are equipped with drying or heating systems to accelerate the curing of the glue.
3) Forming & Pressing: The heart of the machine. A core mold (die) determines the shape, while pressure rollers or belts apply compression to ensure the multiple layers of paper strips bond tightly together.
4) Drive & Transmission: Comprising motors and precision gearboxes, this system provides the power for the winding process. Modern equipment frequently employs variable frequency drives (VFDs) to ensure smooth and stable operation.
5) Precision Cutting: Automatically cuts the square tubes to a preset length. High-end machines utilize CNC flying cutter systems, enabling precise cutting without interrupting the production flow and ensuring clean, smooth cut edges.
6) Control System: The "brain" of the machine, typically consisting of a PLC and a touchscreen interface. Operators use this interface to configure parameters—such as length and speed—and to monitor the operational status of the equipment.
Forming type: spiral winding forming, the craft paper strips are wound spirally around a square mold; this method typically offers higher production speeds
