Product Overview
The Fully Automatic High Speed Paper Cup Machine is an industrial forming system designed for continuous high-output production of paper cups. It integrates automatic paper feeding, ultrasonic side sealing, bottom forming, heating, curling, and stacking into a synchronized forming cycle.
The machine is engineered for manufacturers requiring stable long-hour operation and consistent forming accuracy under high production demand. Each motion unit is coordinated through a PLC control system combined with servo-driven feeding and ultrasonic sealing technology to ensure precise timing between stations.
This structure reduces mechanical deviation during high-speed operation and maintains consistent cup shape stability across continuous production cycles.
Key Features & Industrial Advantages
Heavy-Duty Gear & Open-Cam Drive System
Ensures stable mechanical synchronization under long-hour high-speed operation, reducing wear and vibration compared to chain-driven systems.
Precision PLC + Servo Coordination Control
Provides real-time motion synchronization between feeding, sealing, and forming units for consistent cup geometry.
Ultrasonic Cold-Sealing Technology
Enables stable seam bonding without temperature fluctuation, improving consistency across different paper coatings.
Smart Fault Detection System
Monitors production status through sensors and automatically stops the machine in case of paper misalignment or missing cups.

Frequently Asked Questions
Q: How does the machine handle variations in paper gsm and coatings like PLA?
A: The machine features digital temperature controls and adjustable ultrasonic welding parameters. This allows calibration for paper thicknesses from 150 to 350 gsm and ensures precise thermal activation for PE, PLA, or PBS coatings without damage to the material.
Q: What is the estimated changeover time for different cup sizes?
A: Changing the forming molds and adjusting the mechanical components takes approximately 4 to 8 hours depending on technician experience. Sini Machinery provides detailed step-by-step documentation and engineering support for mold changeover procedures.
Q: How does Sini Machinery ensure zero-leakage rates at 150 pcs/min?
A: Leakage prevention is achieved through a synchronized bottom-heating system and rigid open-cam mechanical pressing. By applying uniform pressure and constant heat to the bottom seam before the final knurling stage, the structural integrity of the seal is maintained at maximum operating speeds.
