Eight-Station Bag-Fed Packaging Machine for White Lentil Granules

Eight-Station Bag-Fed Packaging Machine for White Lentil Granules

The Eight-Station Bag-Fed Packaging Machine for White Lentils is a bag-fed automatic packaging machine specifically designed for packaging white lentils. It features eight workstations (stations) for fully automated production line operation.

1. Core Concept Analysis

White lentils: The product being packaged. This is a granular agricultural product with the following characteristics:

Appearance: Granular, relatively uniform in size, and with good flowability.

Requirements: The packaging process must avoid crushing and accurate metering.

Bag-Fed Packaging Machine: A type of packaging machine.

2. Working Principle: Unlike common "bag-fed packaging machines" (which start with film rolls, fill, and seal), bag-fed packaging machines use pre-made bags. The machine automatically completes the entire process, including bag removal, bag opening, metering and filling, venting (optional), sealing, and discharging.

Advantages:

Various Packaging Styles: A variety of beautiful pre-made stand-up pouches, self-supporting bags, zipper bags, and tote bags can be used, enhancing the quality of your products.

High Efficiency: Particularly suitable for products with limited packaging variations, with stable speeds.

Good Material Adaptability: Filling is smooth and prevents jamming for granular materials like white lentils.

Eight Stations: The machine's level of automation and functional complexity.

A station refers to a workstation on the packaging machine's turntable, each responsible for a specific packaging step. Eight stations mean the machine can perform eight different operations simultaneously, resulting in extremely high efficiency.

3. Workflow (A typical eight-station system may include the following steps):

Station 1 (Bag Loading): A robot or suction cup precisely removes a pre-made bag from the bag magazine.

Station 2 (Bag Opening): A gripper grips the bag opening, and an air blower or suction cup opens the bag opening in preparation for filling.

Station 3 (Metered Filling): This is the core station. Using a gravimetric hopper (multi-head combination weigher) or volumetric measuring cup, the precise amount of white lentils is poured into the opened bag. This is crucial for ensuring the precise weight of each bag.

Station 4 (Vibratory Blanking/Auxiliary Blanking): Gentle vibration or a rod insertion device ensures that there is no residual material on the bag opening and inner wall, ensuring a clean seal.

Station 5 (Venting): For products that require venting, this station compresses the bag to expel air, making the packaging tighter, more aesthetically pleasing, and extending its shelf life (as may be required for white lentils).

Station 6 (Sealing): The core station. A heat sealer heats and pressurizes the bag opening to complete the seal. This can be a straight seal, back seal, or zigzag seal.

Station 7 (Cooling and Shaping): The heat seal is cooled and shaped to ensure a secure and aesthetically pleasing seal.

Station 8 (Unloading and Output): The packaged finished bags are released onto a conveyor belt for the next stage (such as boxing, coding, and metal inspection).

Note: The specific order and functions of the workstations can be customized based on manufacturer design and customer needs. For example, an inspection station (e.g., weight recheck, metal detection) or labeling station may be added.

4. Equipment Workflow Summary

Empty bag → Automatic bag loading → Bag opening → Accurately measure and fill with white lentils → Bag opening trimming → Air removal → Heat-press sealing → Cooling and setting → Finished product output
