Fully Automatic PreMade Plastic Bags Weighing Packing Machine

The eight-station white sugar packaging machine is a medium-to-high-speed packaging equipment specifically designed for the automatic weighing, filling, and sealing of white sugar. It is widely used in the sugar refining and food processing industries.

I. Core Concept

"Eight stations" refers to eight identical weighing or packaging workstations on the machine. These stations rotate around a main shaft (turntable) like wheel spokes, completing their respective tasks sequentially. This design, through parallel operation, greatly increases packaging speed, typically reaching 1200-2000 bags/hour or even higher.

II. Main Features

1. High Efficiency: With eight stations working simultaneously (e.g., one feeding, one weighing, one unloading, and one sealing), the speed is far faster than single-station or dual-station equipment.

2. High Precision: Utilizing a high-precision sensor and computer-controlled multi-head scale for feeding, the weighing accuracy is high, typically controllable within ±0.5 grams, complying with national quantitative packaging regulations.

3. High Degree of Automation: From feeding, metering, bag making/opening, filling, sealing to coding, the entire process is fully automated, reducing reliance on manual labor.

4. Wide Applicability: Capable of packaging various sizes of granulated sugar, such as small or medium-sized bags of 500g, 1kg, 2kg, and 5kg.

5. Good Stability: Mature mechanical structure, strong continuous operation capability, suitable for mass production.

III. Typical Workflow (Taking Pre-made Bag Vertical Packaging as an Example)

1. Feeding: Granulated sugar enters the buffer hopper and weighing hopper of the computer-controlled multi-head scale via an elevator.

2. Precise Metering: The multi-head scale system of the multi-head scale quickly calculates the optimal combination, feeding the precise weight of sugar through the guide chute into the metering cylinders of the eight rotary stations on the packaging machine.

3. Bag Retrieval and Opening: The robotic arm retrieves pre-made plastic bags from the bag magazine and opens the bag opening. Each station corresponds to one bag.

4. Filling: The turntable rotates. When the measuring cylinder containing sugar reaches the filling position, the valve opens, and the sugar falls into the bag below.

5. Sealing: The turntable continues to rotate to the heat-sealing or seam-sealing position for sealing.

6. Output: The sealed bags are released onto the conveyor belt for counting, coding (such as production date, batch number), or boxing.

IV. Core System Components

1. Lifting and Feeding System: Feeds sugar into the weighing hopper.

2. High-Precision Computerized Combined Scale: This is crucial for accuracy and speed. It typically has 8, 10, or 14 scales, and is paired with an eight-station main unit.

3. Eight-Station Rotary Main Unit: The core actuator, responsible for bag holding, filling, and other actions.

4. Bag making or bag picking system: Configured according to whether roll film or pre-made bags are used.

5. Heat sealing/sewing system: Seals the plastic bags.

6. Control system: PLC (Programmable Logic Controller) + touch screen human-machine interface, controls the coordinated operation of the entire machine, allows setting parameters, monitoring status, and calculating output.

7. Conveying and coding system: Conveys finished products and performs coding.
