Working Principle
Centered on "large-capacity bearing + precise weighing control", the ton bag packing machine is suitable for the packaging needs of heavy-weight materials. Its overall process revolves around "bag positioning - material conveying - phased filling - weighing calibration - automatic unloading".
Step 1
Bag Fixing and Positioning
First, empty ton bags are sleeved onto the filling port by manual operation or an automatic bag-feeding mechanism. The equipment clamps the ton bags from the four corners or the edge of the bag mouth through a pneumatic bag-clamping device, ensuring the bag is stable and tightly sealed with the filling port to prevent material leakage or bag displacement during filling. Meanwhile, the bottom of the ton bag is placed on a tray supported by weighing sensors, preparing for subsequent weight monitoring.
Step 2
Material Conveying and Initial Filling
According to the characteristics of materials (such as dry-mixed mortar, ore powder, etc.), the equipment uses a screw conveyor or belt conveyor to transport materials from the storage bin to the filling channel. In the initial stage, the control system activates the high-speed conveying mode, where the screw or belt operates at maximum speed to quickly inject materials into the ton bag. This stage completes most of the target weight, significantly shortening filling time and meeting the efficiency requirements of heavy-weight packaging.
Step 3
Precise Supplementary Filling and Weighing Calibration
When the weighing sensor detects that the material weight in the ton bag is close to the preset value, the control system automatically switches to the "low-speed supplementary filling" mode - the conveying equipment operates at a reduced speed to decrease the amount of material conveyed per unit time. At the same time, the weighing system collects weight data in real time and feeds it back to the control center to dynamically adjust the supplementary filling speed. When the weight reaches the preset value, the conveying equipment stops immediately, and the residual materials in the filling channel are cleared by a small vibration device to ensure weighing accuracy.
Step 4
Automatic Unloading and Bag Sealing
After filling is completed, the pneumatic bag-clamping device is released, and the ton bag moves to the unloading station along with the tray (some equipment is equipped with an automatic conveyor belt). Subsequently, the bag mouth of the ton bag is sealed by heat sealing or rope binding through manual operation or an automatic sealing mechanism to prevent materials from getting damp or scattered, ultimately completing the entire packaging process.
Product Features
Adaptable to Large Production Capacity
Designed for heavy-weight packaging requirements, the equipment can efficiently complete a single large-capacity filling, matching the batch production rhythm of dry-mixed mortar, building materials, and chemical engineering.
High-Precision Weighing System
Equipped with high-precision weighing sensors and an intelligent weighing algorithm to correct errors in real time, ensuring weight deviation is controlled within a very small range even for complex materials.
Robust Stability & Heavy-Duty Design
The main body is made of high-strength welded steel, optimized for heavy-load impacts. The wear-resistant rubber bag-clamping device ensures reliable sealing and an extended operational service life.
Outstanding Environmental Protection
Features an annular dust cover at the filling port linked to a negative pressure dust extraction system. Operates quietly thanks to a noise-reducing motor and shock-absorbing foot pads.
Convenient & Automated Operation
Intuitive touchscreen control system supports parameter storage and retrieval. Automatic bag feeding, clamping, weighing, and unloading functions minimize labor dependence and costs.
Multi-Functional Material Adaptability
Compatible with powders (dry-mixed mortar, cement, ore powder), granules (sand, gravel aggregates), and small blocks (fertilizer granules) by switching different filling ports and clamping devices.

Frequently Asked Questions
What is the packing capacity and weight range of this ton bag packing machine?
The machine has a production capacity of 3 to 6 bags per hour, and it is designed to handle a packing weight ranging from 500kg up to 1000kg per bag.
How does the machine guarantee weighing accuracy?
It features a high-precision weighing sensor with a packing error of ≤0.3%FS. The intelligent control system automatically switches from high-speed conveying to a "low-speed supplementary filling" mode as the bag weight approaches the preset value, ensuring precise calibration.
What types of materials can this machine pack?
This equipment features multi-functional adaptability. It is compatible with powder materials (such as dry-mixed mortar, cement, ore powder), granular materials (such as sand and gravel aggregates), and small block materials (like fertilizer granules).
Which component brands are utilized in the control system?
To guarantee long-term stability and reliability, we cooperate with world-class brands including Siemens PLC, ABB frequency converters, and Schneider air switch contactors.
How does the equipment control dust and environmental pollution?
An annular dust cover is installed at the filling port to enclose dust during operation. The dust is then collected via a negative pressure dust removal system. Additionally, noise-reducing motors and shock-absorbing foot pads are used to control noise levels.
What is your after-sales service and warranty policy?
We offer a 1-year free warranty, one-to-one service, and a 7*24-hour response time. Our technical support includes installation guidance and remote diagnosis, alongside operation and maintenance training.
