Eight-Station Fully Automatic Liquid Beverage and Food Packaging Equipment with Hydraulic Drive

The eight-station liquid packaging machine is a highly efficient and automated rotary liquid filling and sealing device, widely used in the food, beverage, daily chemical, and pharmaceutical industries.

I. Core Working Principle: Rotary Intermittent Motion

The machine's main shaft drives eight station turntables in intermittent rotational motion (usually controlled by a cam divider to ensure precise positioning). Each station completes a specific operation during a stationary period and switches to the next station during a rotating period, repeating the cycle to form continuous production.

II. Typical Workflow of Eight Stations

This is the core of the machine. Although the sequence may vary slightly between different models, a standard eight-station workflow is as follows:

1. Station One: Empty Container Loading

Empty bottles/cups/bags are placed into the clamps or molds using a bottle unscrambler or manually, and automatically clamped and positioned.

2. Station Two: Positioning and Inspection (Optional)

Inspects whether the container is in place and in normal condition. If any items are missing, subsequent stations (such as filling) can automatically skip them to avoid waste.

3. Station Three: First Filling (if required)

For liquids requiring mixed or layered filling, the first liquid is quantitatively filled at this station.

4. Station Four: Second Filling / or Main Single Filling Station

In most cases, this is the main filling station. High-precision quantitative filling is performed using **volumetric filling** (e.g., peristaltic pump, plunger pump) or gravity filling. The filling head can be raised and lowered to prevent foaming.

5. Station Five: Post-Filling Inspection (optional)

The filling volume is checked for compliance using weighing or a level sensor.

6. Station Six: Sealing

This is a critical station. The method varies depending on the packaging material:

For flexible bags: heat sealing or ultrasonic sealing.

7. Station Seven: Cooling and Shaping (for heat sealing)

Cooling and shaping the heat-sealed area ensures a firm and aesthetically pleasing seal.

8. Station Eight: Finished Product Unloading

The fixtures automatically open, and the finished product is pushed onto the conveyor belt for the next stage (e.g., boxing, coding, cartoning).

Note: The entire process is fully automated under the control of a PLC (Programmable Logic Controller) and a touchscreen human-machine interface, allowing adjustment of all parameters such as speed, filling volume, and temperature.

III. Main Application Features

1. High Efficiency: Eight stations operate simultaneously, ensuring stable output. Speed ​​varies depending on the product, typically reaching 2000-6000 units or more per hour.

2. High Precision: Employing a high-precision pump or servo control system, filling accuracy can reach ±0.5% - ±1%.

3. High Adaptability: By changing the filling head, fixtures, and molds, it can adapt to containers of different shapes and capacities (e.g., round bottles, square boxes, irregularly shaped cups).

4. Hygiene and Safety:

The main material contact parts are made of 316/304 stainless steel, meeting GMP (Good Manufacturing Practice) requirements.

5. Easy to disassemble and clean (CIP/SIP function optional), with no unsanitary corners.

6. High Stability: Core transmission components (such as dividers, servo motors, and guide rails) are from well-known brands, ensuring stable continuous operation over long periods.

7. Intelligent: Equipped with functions such as production counting, fault alarms, data recording, and formula storage.

IV. Main Application Industries and Products

1. Food and Beverage: Yogurt, jelly, pudding, sauces, juices, milk, hot pot base.

2. Daily Chemicals: Laundry detergent, hand soap, shampoo, lubricating oil.

3. Pharmaceuticals and Chemicals: Disinfectants, eye drops, oral liquids, veterinary drugs, reagents.
