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", with specific steps as follows:
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.
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.
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.
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, and its hourly packaging quantity can match the batch production rhythm of industries such as large-scale dry-mixed mortar, building materials, and chemical engineering, preventing heavy-weight material packaging from becoming a production bottleneck.
High-Precision Weighing
Equipped with high-precision weighing sensors and combined with an intelligent weighing algorithm, it can correct filling errors in real time. Even for materials with large differences in fluidity (such as dry-mixed mortar with mixed coarse and fine particles), it can ensure that the weight deviation of each bag is controlled within a very small range, which not only meets the measurement standards of industrial production but also reduces material waste.
Robust Stability Design
The main body of the equipment is made of high-strength steel through welding, and the load-bearing structure is optimized by mechanics, which can stably withstand the weight impact of heavy-weight materials. At the same time, the bag-clamping device is made of wear-resistant rubber material, which not only ensures sealing performance but also extends service life, making it suitable for continuous heavy-duty operation scenarios.
Outstanding Environmental Protection
An annular dust cover is installed at the filling port, which can firmly control the dust generated during the filling process in a closed space, and then the dust is extracted and collected through a negative pressure dust removal system, greatly reducing dust emissions. In addition, the equipment uses a noise-reducing motor and shock-absorbing foot pads during operation to effectively control noise, complying with the environmental protection operation requirements of the workshop.
Convenient Operation
Equipped with a touchscreen control system, it allows intuitive setting of parameters such as packaging weight and filling speed, and supports parameter storage and retrieval. Meanwhile, functions such as automatic bag feeding, bag clamping, weighing, and unloading greatly reduce manual operations, requiring only a small number of workers to complete equipment monitoring and auxiliary operations, significantly lowering labor costs.
Multi-Functional Adaptability
It can not only be used for packaging powdery materials such as dry-mixed mortar, cement, and ore powder but also be compatible with granular materials (such as sand and gravel aggregates) and small block materials (such as fertilizer granules). By replacing filling ports and bag-clamping devices of different specifications, it can adapt to ton bags of various sizes, featuring strong versatility.
