Sembsun 4 Stations Rotary Premade Bag Packing Machine
Why is Sembsun’s four-station premade bag packaging machine said to have efficient production, flexible adaptation, precise control and high degree of automation?
- Multiple stations work together: four stations (bag taking, bag opening, filling, and sealing) operate synchronously, greatly improving the packaging speed
- Support various bag types: compatible with stand-up bags, aluminum foil bags, zipper bags, special-shaped bags, etc.
- Intelligent temperature-controlled sealing: ensures a firm seal, avoids air leakage or scalding through the bag film, and improves the packaging qualification rate
Sembsun Automatic 4 Stations Doy Bag Packing Machine
What kind of bags can be packed with a four-station premade bag packaging machine?
1. Stand-Up Pouch
Features: The bottom can stand up, which is convenient for display and storage. It is suitable for liquids, powders, granules, etc.
2. Eight-Side Seal Pouch
Features: Eight-side seal design, strong three-dimensional sense, good load-bearing capacity, suitable for large-capacity packaging.
3. Spout Pouch
Features: With a suction nozzle or a screw cap, it is easy to open and close multiple times, suitable for liquids or viscous materials.
4. Four-Side Seal Pouch
Features: The four sides are completely sealed, moisture-proof and leak-proof, with a simple structure and low cost.
5. Shaped Pouch
Features: Personalized design (such as heart shape, gourd shape) to enhance product recognition.
6. Zipper Pouch
Features: The bag mouth has a zipper, which can be repeatedly sealed and has strong freshness preservation.

What are the functions of the four workstations?
Bag Picking Station
Purpose: The robot or suction cup device accurately grabs the pre-made bag (pre-made empty packaging bag) from the bag library and transfers it to the next station.
Key point: Ensure that the bag is picked up accurately and not stuck or damaged.
Bag opening station
Purpose: To open the bag opening through airflow (positive/negative pressure) or mechanical clamps to prepare for subsequent filling.
Key points: It needs to adapt to different bag types (such as self-supporting bags, back-sealed bags, etc.) to ensure that the opening is sufficient and stable.
Filling station
Purpose: Use with feeding/metering devices (such as linear scales, screws) to quantitatively fill materials (such as powders, liquids, granules) into opened bags.
Key points: Precision control (anti-leakage), matching of rotation speed and feeding speed.
Sealing station
Purpose: Heat seal (heat-press seal) the bag mouth after filling to ensure the airtightness of the package.
Key point: Sealing temperature/pressure adjustment to avoid leaking or burning through.
Sembsun Service Term
Through the continuous collaborative operation of four stations (bag taking, bag opening, filling, and sealing), the prefabricated bags can be automatically taken out, opened, quantitatively filled, and sealed without manual intervention.
Usually 800-1500 bags/hour, depending on the bag type, material characteristics and equipment model (e.g. D-240 model is about 600-900 bags/hour).
Accuracy range: ±1-5 grams (the error is smaller for powders, and may be slightly larger for granules or viscous materials).
Influencing factors: material fluidity, metering device (screw/weighing), equipment vibration, etc.
Yes, but it needs to be equipped with a drip-proof filling head and a more tightly sealed sealing station. Viscous materials may require a piston pump filling system.
High failure points: wear of bag opening suction cups and aging of sealing heating elements.
Maintenance suggestions: Regularly clean photoelectric sensors, lubricate moving parts, and replace wearing parts (such as sealing strips).
Advantages: Suitable for pre-made bags (more exquisite pattern printing), more diverse bag types.
Consider:
Bag type and size (matching equipment station parameters).
Material properties (powder/liquid/granules are suitable for different filling systems).
Productivity requirements (e.g., high-speed machine is required for ≥1,000 bags per hour).
