Packaging Machine

The OFEC Packaging Machine is the terminal equipment in organic fertilizer production lines, designed to automatically weigh and bag finished organic fertilizer granules after cooling and coating, facilitating storage and transport.

Product Overview

OFEC offers a variety of packaging solutions. Based on packaging specifications, we provide ton bag packaging machines (for large-capacity packaging, typically 500–1000 kg/bag) and open-mouth bag / valve bag packaging machines (for standard 25 kg/bag or 50 kg/bag packaging). Depending on capacity requirements, single-scale and double-scale configurations are available – the double-scale option enables alternating or parallel operation, significantly improving packaging efficiency.

After cooling and coating, organic fertilizer granules generally need to be bagged for storage and transport. Packaging is the final step before finished products leave the factory, directly affecting product presentation and logistics efficiency.

Equipment Components

The packaging machine mainly consists of the following components:
● Scale Frame: Supports the entire equipment
● Feeder: Delivers material from the storage hopper to the weighing hopper, with fast and slow feeding stages
● Weighing Hopper: Temporarily holds material to be weighed
● Discharge Chute: Guides weighed material into the bag
● Pneumatic Bag Clamp: Secures the bag opening
● Load Cells: Detect material weight in real time
● Weighing Control Instrument: Displays and controls the weighing process
● Electronic Control System: Full machine automation control
Optional Auxiliary Equipment:
● Hemming machine
● Industrial sewing machine
● Automatic palletizing system (robotic arm or palletizer)

Working Principle

The packaging machine operates as follows: finished organic fertilizer granules are conveyed into the storage hopper via the conveying system. The feeder then delivers material into the weighing hopper. Load cells continuously detect the material weight in real time. When the preset weight is reached, the control system signals the feeder to stop and opens the discharge gate at the bottom of the weighing hopper, releasing the material through the discharge chute into the bag held in place by pneumatic bag clamps. After bag filling is complete, the bag clamps automatically release and the filled bag is conveyed away.

Open‑mouth bag packaging: The bag is folded by a hemming machine and then sealed by an industrial sewing machine, ensuring a secure closure.

Ton bag packaging: Using loop‑type or ear‑type ton bags, filled bags are removed by crane or forklift.

Automatic palletizing: An automatic palletizing system can be installed after the packaging machine, using a robotic arm or palletizer to neatly stack bags on pallets according to preset patterns – saving labor and improving efficiency.
