The rotary pre-made bag washing powder packaging machine utilizes a rotary multi-station design. It uses pre-made bags and automatically completes a series of operations, including bag removal, bag opening, quantitative filling, venting, sealing, and discharge, achieving high-speed packaging of washing powder.
Pre-made bags: Bags are pre-printed and pre-formed finished bags, unlike vertical packaging machines that use roll film for on-site bag production.
Rotation: The machine's main actuator is a turntable that rotates continuously or intermittently, surrounded by multiple stations that perform different operations simultaneously, greatly improving production efficiency.
1. Workflow (Example: 8-Station)
The turntable pauses after each rotation (e.g., 45°) to complete the operation of one station before continuing to the next. The entire process is parallel and continuous, ensuring extremely high efficiency.
Station 1 (Bag Loading): The bag gripper is in the bag removal position, and the bag removal mechanism clamps a new bag onto the gripper.
Station 2 (Bag Opening): The device securely opens the bag opening.
Station 3 (Bag Inspection): Checks whether the bag opening is fully open. If not, the machine may reject the bag or trigger an alarm at this station.
Station 4 (Filling): The screw filling head descends to the bag opening and metered amounts of detergent are added.
Station 5 (Venting): The bag is vibrated or squeezed to remove air.
Station 6 (Sealing): The heat sealer seals the bag opening.
Station 7 (Cooling/Shaping): The seal area is cooled.
Station 8 (Unloading): The bag gripper releases, and the finished bag falls onto the output conveyor. The turntable returns to Station 1 empty, starting the next cycle.
2. Advantages and Features
High Efficiency: Multiple stations operate in parallel, achieving speeds of 40-80 bags/minute or even higher, far exceeding single-station linear packaging machines.
High Precision: Utilizing screw metering or load cells, the filling accuracy is high and meets national standards.
Wide Applicability: Suitable for a variety of pre-made bags (paper-plastic composite, plastic composite, stand-up pouches, zipper bags, etc.).
High Automation: Fully automated from bag removal to finished product delivery, requiring only one person, saving labor.
Beautiful Packaging: Pre-made bags feature exquisite printing and excellent sealing quality, resulting in high-quality finished products.
Easy Production Changeover: Parameters can be adjusted and grippers and filling heads can be replaced via the touchscreen, allowing for quick adaptation to different bag sizes and products.
