granule bag packaging machine

Developed by GLZON’s professional technician team, the automatic plastic granule bag packaging machine (double bucket gravity type) is specially engineered for high-efficiency granule bagging. It is widely applied to plastic granules, wheat, maize, paddy, sunflower seeds, beans, peanuts, animal feed, as well as river sand, sea sand and other granular/bulk materials, delivering stable performance for batch packaging tasks.

Brand： GLZON

Model： GZM-50GI

Gravity Bagging Machine | Automatic Plastic Granule Bag Packaging Machine

Application: Automatic packaging of agricultural cereals, industrial granular materials, and bulk materials

Overview

Core Advantages for Granule Bag Packaging

? MCU Microprocessor Control: Equipped with a digital display screen for intuitive operation, clear data reading, and easy monitoring of granule filling progress.

? High-Precision Granule Weighing: Ensures accurate weight measurement for each granule bag, meeting strict industrial packaging standards and reducing material waste.

? Flexible Parameter Setting: Convenient to set, store and modify weighing parameters for different types, sizes and densities of plastic granules and other granular materials.

? Intelligent Data Statistics: Automatically counts total filling tons and granule bag quantities, facilitating production management and inventory control.

? Full-Automatic Granule Packaging Flow: Integrates automatic weighing, discharging and bag clamping, minimizing manual intervention and improving packaging efficiency.

? Auto/Semi-Auto Tare Removal: Deducts the weight of packaging bags automatically or semi-automatically, ensuring precise measurement of granule net weight.

Main Components & Technical Parameters (Granule Bag Focus)

Components	Specifications	Details for Granule Bag Packaging
Main Filling Machine	Control System	MCU instrument with digital display screen, easy to operate for granule packaging parameters.

Working Requirements

Labor Demand: Only 2 operators needed for efficient granule bag packaging:

Operator 1: Places empty granule bags under the discharging outlet (simple operation, no professional skills required).
Operator 2: Assists the sewing machine for granule bag sealing, ensuring tight and neat stitching.

Granule Bag Packaging Working Procedure

Manual Bag Placing: Operators place empty woven sacks (or plastic bags) under the discharge port, clamped by the sensor-controlled clamper.
Automatic Filling: The machine starts vibrating feeding according to preset granule weight parameters, with three-speed adjustment to avoid spillage.
Automatic Weighing: High-precision weighing system stops feeding once the target granule weight is reached, ensuring accuracy.
Automatic Conveying: The belt conveyor transports the filled granule bags to the sewing station smoothly.
Semi-Automatic Sealing: The sewing machine seals the granule bag mouth with manual assistance, completing the whole packaging process.
