High Speed Automatic Paper Cup Forming Machine

The High-Speed Automatic Paper Cup Forming Machine by Sini Machinery is an industrial-grade manufacturing system engineered for continuous, mass production in the food and beverage packaging sectors. Operating at a stable capacity of 80–160 pcs/min, this advanced line integrates automatic paper feeding, side sealing, bottom punching, heating, rim curling, and auto-stacking into one synchronized operation.

Designed for heavy-duty production environments, the machine features an open-cam transmission system that replaces traditional chain drives to maximize mechanical stability and precision. This model delivers the structural rigidity and continuous output required by medium-to-large packaging factories handling high-volume contracts and tight delivery schedules.

High-Speed Stability: Optimized mechanical architecture allows continuous operation up to 160 pcs/min while maintaining strict dimensional tolerances.

Open-Cam Driving System: Uses high-precision cylindrical cams to ensure synchronized motion, minimizing mechanical wear and reducing maintenance requirements.

Intelligent PLC Control: Equipped with a premium touchscreen PLC system for real-time monitoring of temperature, pneumatic pressure, and timing parameters.

Servo-Driven Feeding System: Precision servo motors control the paper blank delivery, maintaining an alignment accuracy within ±0.2 mm to optimize material utilization.

Advanced Sealing Technology: Features heavy-duty ultrasonic side sealing and hot-air bottom sealing to ensure airtight bonding for single and double PE-coated paper.

Automated Collection: Fully integrated automatic cup stacking and counting system streamlines downstream packaging and lowers manual handling requirements.

Precision Servo Feeding: Blank paper is fed into the system with exact alignment control.

Side Wall Forming: The cup body is shaped and bonded instantly via ultrasonic or hot-air sealing.

Bottom Punching: Bottom disks are precision-punched directly from the paper roll to maximize yield.

Bottom Heating & Knurling: Multi-stage heating elements activate the protective coating to create a secure, airtight bottom seal.

Rim Curling & Shaping: Specialized curling tools form a smooth, rigid top rim for comfortable drinking and secure lid fitment.

Pneumatic Collection: Finished cups are pneumatically transferred to the stacking unit for systematic packaging.

This equipment supports standard single and double PE-coated paper options alongside biodegradable PLA-coated and water-based barrier materials used in sustainable packaging.

Target Industries:
• Industrial-scale disposable container manufacturing plants
• Beverage, coffee, and milk tea brand supply chains
• QSR, takeaway, and fast-food packaging manufacturing lines
•Contract packaging facilities requiring multi-size production flexibility
