The six working processes of a cup, bowl, and box filling machine include automatic container loading, automatic container cleaning, automatic filling, automatic sealing, automatic coding/inkjet printing, and automatic container discharge.
1. Automatic Loading of Cup, Bowl, and Box Containers
The fully automatic filling machine uses a conveyor to automate container loading, eliminating the need for manual placement into molds. High-precision sensors and the conveyor system work together to ensure accurate positioning and a continuous, stable supply of containers for subsequent processes.
2. Automatic Cleaning of Cup, Bowl, and Box Containers
Depending on customer requirements, the equipment can integrate an automatic cleaning module. High-pressure spraying or ultrasonic cleaning technology cleans the inner walls and outer surfaces of containers, removing impurities and microbial contamination. This function may extend the single-cycle operation time, but it significantly improves product hygiene standards. It is suitable for food, pharmaceutical, and other fields with high cleanliness requirements. For such modules, Hansheng Automation can machine custom nozzle holders, guide rails, fixture plates, and changeover parts from customer drawings in single pieces or small batches.
3. Automatic Filling of Cup, Bowl, and Box Containers
The equipment is equipped with a material storage tank with a stirrer. Screw pumps or piston pumps provide precise metered filling. The stirring device ensures material uniformity and prevents separation. The filling head uses an anti-drip design and is controlled by a servo motor, allowing filling speed and accuracy to be adjusted for materials of different viscosities. The error range is controlled within ±0.5%.
4. Automatic Sealing of Cup, Bowl, and Box Containers
The machine supports two sealing forms: roll film and sheet film, using heat-sealing technology. A temperature control system and pressure adjustment device work together to ensure sealing strength meets requirements without wrinkles. This process can integrate nitrogen flushing to form modified atmosphere packaging, extending product shelf life. It is especially suitable for packaging oxidizable foods.
5. Automatic Coding/Inkjet Printing on Cup, Bowl, and Box Containers
The equipment has a built-in high-resolution coding system. It can print production batch numbers, expiration dates, QR codes, and other information on the surface of sealed containers. Non-contact inkjet technology supports dynamic coding and variable data input, ensuring clear and traceable markings. Some models can be upgraded with a laser coding module for permanent marking.
6. Automatic Discharge of Cup, Bowl, and Box Containers
Finished products that have completed all processes are automatically conveyed to a collection area through slide rails or robotic arms, achieving seamless connection with downstream packaging lines. The equipment is equipped with an intelligent inspection system that automatically rejects nonconforming products, ensuring the qualification rate of discharged products. Discharge speed can reach 60–120 pieces per minute, with specific parameters adjusted according to model specifications.
The above processes are coordinated automatically through a PLC control system. Buffer transition zones are set between processes to prevent material accumulation or process conflicts. The modular design supports functional expansion, allowing flexible configuration of additional modules such as cleaning, sterilization, and weight inspection according to production needs.
