Rotary Cup Granule Packaging Machine
Share to:
The Rotary Cup Granule Packaging Machine is designed for precise and efficient packaging of granular products using a volumetric cup dosing system. Each filling cycle is controlled by adjustable measuring cups to ensure consistent weight output. Equipped with a ribbon coding printer for date marking and a finished product conveyor for easy collection, this machine offers a compact and practical solution for automated packaging. It is ideal for industries requiring stable performance, simple operation, and reliable packaging quality.
Machine Overview and Functional Description
This Rotary Cup Granule Packaging Machine is a fully automatic 4-side sealing packaging machine, designed for efficient and consistent granule packing. The sealing process follows a structured sequence: vertical sealing first, followed by horizontal sealing. During vertical sealing, additional pressing rollers apply secondary compression, enhancing sealing strength and ensuring leak-proof packaging.
The machine allows flexible adjustment of packaging size by replacing the forming collar. The changeover process is simple and efficient, typically completed within 10–20 minutes, minimizing downtime and improving production efficiency.
The working process begins with materials flowing from the hopper into the rotary disc via an inclined chute. Inside the rotary system, specially designed paddles guide the granules into layered volumetric measuring cups (multi-layer cups). These cups can be easily replaced to accommodate different filling weights, offering excellent flexibility for various product specifications.
Once filled, the measured granules are discharged into the formed bags. The system then completes sealing and cutting automatically, ensuring uniform bag appearance and consistent output quality. This machine combines stable structure, precise dosing, and efficient sealing, making it an ideal solution for small to medium-sized granule packaging operations.

Structural Design and Working Principle
1. Film Pulling System
The film pulling system ensures stable and smooth film transportation during operation. It maintains consistent tension and alignment, preventing film deviation and ensuring accurate bag forming, even at continuous working speeds.
2. Rotary Measuring Cups
The rotary disc is equipped with multi-layer volumetric cups, designed for precise and repeatable dosing. By simply replacing the cups, operators can quickly adjust packaging weight, making it highly flexible for different products.
3. 4-Side Sealing Mechanism
The machine adopts a four-side sealing structure with reinforced vertical sealing rollers. The secondary pressing design improves sealing strength, ensuring tight, leak-proof, and visually clean packaging results.
4. Ribbon Coding Printer
Equipped with a ribbon coding system, the machine allows real-time printing of production date, batch number, or expiry date directly on the packaging film, improving product traceability and compliance
FAQs
1. What products can this machine package?
It is suitable for small to medium-sized granules such as salt, sugar, seeds, beans, and detergent granules.
2. How is the filling weight controlled?
The machine uses volumetric measuring cups. Different weights can be achieved by adjusting or replacing the cups.
3. Can the bag size be adjusted?
Yes. Bag size can be adjusted by changing the forming collar. The process takes about 10–20 minutes.
4. What is the maximum particle size allowed?
The maximum recommended size is similar to shelled peanuts. Larger particles may affect accuracy and machine performance.
5. Does the machine support date printing?
Yes. It is equipped with a ribbon coding printer for printing production date, batch number, and other information.
