The automatic inline cup filling and sealing machine is designed to automatically feed empty cups, detect their position, fill, seal, and discharge finished products in a continuous production process.
The inline cup filling and sealing machine is constructed from 304 stainless steel and anodized aluminum, making it suitable for demanding food production environments, including those with moisture, steam, oil, acidity, and salt exposure. The frame is also washable with water for easy and hygienic cleaning.
It is equipped with high-quality imported electrical and pneumatic components to ensure stable long-term operation, minimize downtime, and reduce maintenance requirements.
Main Features
1.Conveyor System
Powered by a servo motor with a planetary gear reducer, the conveyor operates smoothly and accurately at high speed. The servo-driven motion helps prevent product splashing while ensuring precise cup positioning.
2.Automatic Cup Loading
The inline cup filling and sealing machine uses advanced cup separating and pressing technology to prevent cup damage or deformation. A vacuum suction system accurately places empty cups into the molds.
3.Empty Cup Detection
Photoelectric or fiber optic sensors automatically detect whether cups are present in the molds, preventing filling or sealing errors and reducing product waste and cleaning time.
4.Filling System
Equipped with a piston filling system and cup lifting function for clean, accurate filling without splashing or leakage. An optional CIP (Clean-In-Place) system is available for easier cleaning.
5.Sealing and Cutting System
Features automatic film feeding, film alignment, waste film collection, and heat sealing functions. The sealing system ensures accurate positioning on printed film and uses an Omron PID temperature controller for reliable and consistent sealing quality.
6.Product Discharge System
Automatically discharges sealed cups and transfers them smoothly to the next production stage.
7.Automatic Control System
Integrated with PLC control, touchscreen interface, servo system, sensors, solenoid valves, and relays for stable and user-friendly operation.
8.Pneumatic System
Includes air valves, air filters, pressure gauges, sensors, solenoid valves, cylinders, and silencers to ensure reliable pneumatic performance.
9.Safety Protection System
Optional safety guards made from stainless steel and transparent PC panels provide operator protection and include safety switches for safer operation.
