Pet Product Packaging Machine for Cat Litter, Cat Food, Dog Food, Treats, and Freeze-Dried Products with Dust Removal Device

The "pre-made bag cat litter packaging machine" is a crucial and common piece of equipment in the pet supplies manufacturing industry. It is specifically designed to automatically fill various forms of cat litter, such as bentonite, tofu litter, crystal litter, and mixed litter, into pre-made packaging bags.

I. What is a pre-made bag cat litter packaging machine?

This is an automated packaging device that uses pre-made bags, often with a resealable zipper (stand-up pouch) on the back. Its workflow is as follows: Pick Bag -> Open Bag -> Fill -> Compact (Optional) -> Evacuate Air / Seal -> Output Finished Product.

It operates on a similar principle to another common machine, the "bag-giving packaging machine," but is optimized for the characteristics of cat litter (such as dust, varying particle sizes, unstable bulk density, etc.).

II. Key Features and Advantages

1.Aesthetically Pleasing Packaging: Pre-made bags are often exquisitely printed and can be used directly as point-of-sale packaging, with an attractive appearance that enhances the product's grade.

2.High Degree of Automation: The process from bag picking to finished product output is fully automated, significantly saving labor and improving production efficiency.

3.Zipper Sealing Function: This is an essential function for cat litter packaging. The machine accurately opens and heat-seals the zipper, ensuring seal integrity and facilitating multiple uses for the consumer.

4.Strong Adaptability:

Bag Types: Can handle various bag types like back-gusseted stand-up pouches, four-side-seal stand-up pouches, and handle bags.

Materials: By changing different feeding devices (such as screw feeding, gravity feeding, vibration feeding), it can adapt to cat litters with different physical properties like bentonite granules, long tofu cat litter strips, and fine crystal sand.

5.Integrated Compaction and Air Evacuation Functions:

Compaction: Vibrates the bag to compact the litter inside, preventing bag bulging during transportation and allowing for denser packing.

Air Evacuation: An air evacuation device can be optionally equipped to remove air from the bag, making the package more compact and saving storage and transportation space, especially suitable for bentonite litter.

6.Precise Metering: Uses high-precision electronic scales (e.g., weigh-fill type) or volumetric metering to ensure consistent weight per bag, complying with trade specifications.

III. Basic Workflow

1.Bag Loading: A robotic arm automatically picks a pre-made bag from the bag storage magazine.

2.Bag Opening: Uses suction cups or grippers to open the bag mouth and place it over the filling nozzle.

3.Filling: The measured cat litter falls into the bag through the filling nozzle.

4.Compaction/Leveling: During or after filling, high-frequency vibration compacts and levels the litter.

5.Air Evacuation (Optional): If this function is configured, air inside the bag is removed at this stage.

6.Heat Sealing: The bag mouth is heat-sealed, including the inner zipper seal and the outer bag mouth seal.

7.Output: The finished, sealed bag is conveyed out via a conveyor belt and can be connected to a labeler or coder for printing the date/batch number.

IV. Key Equipment Components

1.Main Frame & Control System: PLC + Touchscreen HMI, the brain of the equipment.

2.Bag Loading Mechanism: Servo motor-driven robotic arm responsible for precise bag picking and opening.

3.Metering System: Often a weigh-fill hopper scale, offering the highest accuracy and adapting to changes in litter bulk density.

4.Filling System: Includes a storage hopper, feeding mechanism (e.g., screw, gate), and dust-proof design.

5.Compaction Device: High-frequency vibrator, usually located below or to the side of the filling station.

6.Air Evacuation System: Vacuum pump and suction nozzle.

7.Heat Sealing System: Heating plate and cooling plate to ensure a secure seal for both the zipper and the bag mouth.

8.Conveyor Belt: Connects various workstations and transports bags and finished products.
