Product Overview
The Medium Speed Automatic Paper Cup Machine is designed for continuous forming production with a stable output range of 70–90 cups per minute. The system integrates cup forming, side sealing, bottom processing, rim curling, and automatic stacking in a fully synchronized mechanical cycle.
The machine is engineered around long-cycle operational stability, ensuring consistent forming accuracy under sustained production conditions. Each station operates with fixed timing coordination to maintain stable cup geometry, sealing strength, and output consistency.
Key Technical Advantages
Precision Cam Drive System
Adopts an open-cam distribution structure combined with heavy-duty gear transmission, ensuring precise mechanical synchronization across all forming stations during continuous operation.
High-Efficiency Ultrasonic Sealing
Uses a high-power ultrasonic side-sealing system to achieve strong, clean seams for both single and double PE-coated paper without damaging printed surfaces or causing edge burning.
Automatic Lubrication System
Equipped with a filtered circulation lubrication system that delivers controlled oil supply to key transmission and friction components, maintaining stable mechanical performance.
Intelligent Production Monitoring
Integrated sensor system monitors feeding, forming, and bottom processing. The machine automatically stops when abnormal feeding or forming errors are detected, reducing material waste and protecting tooling.

Working Principle
The production process follows a continuous synchronized cycle:
Paper feeding → Side sealing → Cup forming → Bottom feeding → Bottom sealing → Rim curling → Automatic stacking
Each station operates under fixed mechanical timing. The synchronized movement ensures consistent forming pressure, sealing integrity, and geometric stability across continuous production cycles.
