Fully Automatic Premade Bag Vacuum Rotary Packaging Machine

A vacuum rotary packaging machine is an automated device capable of processing multiple packaging bags simultaneously, automatically completing a series of processes including bag picking, opening, filling, vacuuming, sealing, and unloading. Its core advantages lie in its high efficiency and high automation, significantly increasing the packaging speed of the production line.

I. Key Functions and Technical Highlights

1. Intelligent Control and Operation: Most machines utilize PLCs and touchscreens from brands such as Mitsubishi, enabling parameter setting, recipe storage, fault self-diagnosis, and one-button start/stop, making operation extremely convenient.

2. Automated Adjustment: When changing to different sized packaging bags, parameters can be input via the touchscreen, and the servo motor automatically adjusts the bag width and related mechanisms, eliminating the need for manual tools and reducing changeover time to less than 5 minutes.

3. Comprehensive Detection System: The equipment is equipped with multiple sensors that automatically detect abnormalities such as "no bag," "unopened," and "unfilled," automatically rejecting defective products and reducing waste.

4. High Safety Standards: Equipped with safety door interlock switches, light curtains, and emergency stop buttons, the equipment will immediately stop operating if the door is opened or someone enters the danger zone, ensuring operator safety.

5. Superior Materials and Craftsmanship: Parts in contact with food are typically made of 304 stainless steel, meeting FDA and EU standards to ensure food hygiene and safety.

II. Core Working Principle Its workflow is generally as follows:

1. Bag Pickup: A robotic arm picks up a packaging bag from the side bag reservoir.

2. Printing: Optional, printing the production date or batch number on the bag.

3. Bag Opening: The bag opening is opened using a suction cup, and air is blown to fully open the bag.

4. Filling: The measured product is injected into the bag through a funnel (can be connected to a computer-controlled scale, liquid filling machine, etc.).

5. Shaping: For products requiring a regular shape, vibration or tapping is applied.

6. Pre-sealing: The bag opening is gently pressed to prevent the product from falling out when entering the vacuum chamber.

7. Vacuum Sealing: The bag enters the vacuum chamber at the workstation, where air is evacuated and heat-sealed.

8. Cooling and Shaping: After heat sealing, the bag cools naturally, making the seal more secure.

9. Bag Unloading: The finished bag is automatically released and slides onto the conveyor belt to enter the next stage.

III. Main Advantages

1. High Speed: This is its biggest advantage. Due to the parallel operation of multiple workstations, the speed far exceeds that of single-station or dual-station equipment, typically reaching 40-60 bags/minute, and some models can even reach over 80 bags/minute.

2. Smooth Operation: The continuous rotary motion results in less impact, lower noise, and less mechanical wear compared to linear reciprocating motion.

3. High Space Utilization: Utilizing a circular layout, the footprint is typically smaller than that of linearly arranged equipment with the same number of workstations.

4. Strong Compatibility: By changing the robotic arms and molds, it can adapt to various bag types, such as stand-up pouches, four-side seal bags, and zipper bags.
