Pre-Made Bag Rotary Fill Seal Packaging Machine

Pre-Made Bag Rotary Fill Seal Packaging Machine used to automate the packaging process, which can complete the steps of filling, sealing and packaging of pre-made bags. It is suitable for different types of products such as powder, granular, liquid, etc. Pre-made bag rotary filling and sealing packaging machine is widely used in food, chemical, pharmaceutical and other industries, which helps to improve production efficiency and packaging quality.

How does the pre-made bag rotary fill and seal packaging machine work?

① Automatic bag feeding: Prefabricated bags (such as self-supporting bags and zipper bags) are accurately grabbed by vacuum suction cups or mechanical grippers and transferred to the rotating station. The bag mouth is automatically opened by the guide device to ensure smooth filling channels.

② Filling: According to the product type (granules, powders, liquids), servo screw metering, gravity filling or pumping system is used, with an accuracy of ±0.5%.

③ Gas Flushing (optional): Oxygen-sensitive products (such as nuts and milk powder) can be integrated with a nitrogen replacement system to extend the shelf life.

④ Sealing: The rotary multi-station design completes the bag mouth sealing by heat sealing knife or ultrasonic sealing.

⑤ Ejection: The finished bag is exported by the conveyor belt and can be connected to an automatic cartoning machine or labeling machine to achieve full production line operation.

Which industries are pre-made bag rotary filling and sealing packaging machines suitable for?

Pre-made bag rotary fill seal packaging machine has a wide range of applications in many industries and fields. The following are some common application areas:

-Food industry: can be used to package biscuits, candies, puffed foods, snack foods, frozen foods, etc.

What are the advantages of pre-made bag rotary fill seal packaging machine？

High speed and high efficiency: The rotary design enables continuous operation, with a speed of 40-90 bags/minute517, far exceeding the linear packaging machine.

Precise control: PLC+touch screen system adjusts parameters (temperature, speed, filling volume) to adapt to different bag types and materials.

Flexible adaptation: It can handle prefabricated bags with a width of 80-300mm, and the materials include high barrier films such as PET/AL/PE and KNY.

Low failure rate: Equipped with automatic lubrication system and fault diagnosis module to reduce downtime

Pre-made bag rotary filling and sealing packaging machine composition structure

The structure of the pre-made bag rotary fill and seal packaging machine can include the following main parts:

Bag supply system: used to provide pre-made bags and convey them to the filling area.

Filling system: used to accurately fill powder or granular materials from the hopper or feeding device into the pre-made bags.

Sealing system: used to seal the filled pre-made bags to ensure the sealing and freshness of the products. The sealing system usually adopts heat sealing technology, including heating elements, pressure devices, sealing knives, etc.

PLC control system: used to control the operation and parameter settings of the packaging machine.

Transportation system: used to transport the filled and sealed pre-made bags from the filling area to the packaging area or the next process.
