Core Operating Principles
Cylindrical packaging forming machines primarily operate under two mainstream modes:
Plastic Cylinder Forming Mode: Driven by a PLC control system, sheet materials (such as PVC, PP, or APET) are rolled into a cylindrical shape by a curling unit. Side bonding is then achieved via adhesive application or ultrasonic welding, completing the cylinder formation in a single pass; some models can also perform punching operations simultaneously.
Cylinder Wrapping Mode: This involves two wrapping methods-radial and axial. In radial wrapping, powered rollers drive the cylindrical load to rotate, enabling wrapping around the cylinder's curved surface. Axial wrapping involves wrapping the entire cylindrical object along its axis to create a dust-proof and moisture-proof sealed package.
Core Components and Process
The equipment comprises a feeding unit, a curling unit, a pressing/bonding unit, and an output unit. Integrated with a PLC and HMI (Human-Machine Interface) system, it automates the entire workflow-from material loading and flattening/cutting to rolling/forming and bonding/setting. Fully automatic models can achieve production rates of 40–60 units per minute.
