Technical & Structural Advantages
Engineered for Performance and Reliability
Our machine's design is focused on efficiency. The use of a single cylinder for four-station movement creates a highly compact structure, which ensures a fast response time and significantly reduces the failure rate. Furthermore, the super filter function actively combats vibration and electrical interference, which is critical for maintaining a stable and accurate weighing process, even in busy industrial environments.
Operator-Focused Controls
Ease of use is paramount. The system is managed by a high-precision controller that is simple to operate. For maximum convenience, it includes a one-key recovery function, allowing the operator to instantly press the reset key to return to the default parameters. A reserved RS232/485 interface is also included, allowing for straightforward integration and data communication with other factory management systems.
Quality Control and Component Philosophy
Commitment to Quality Manufacturing
Every grain packing machine we produce is subject to a rigorous quality control regimen. The process starts with the inspection of all incoming materials and continues through every stage of fabrication and assembly. Before shipment, each machine is fully assembled and undergoes extensive testing with materials similar to the client's product to ensure it performs flawlessly and meets all technical specifications. Our design also emphasizes energy efficiency, consuming only 1KW of power, which helps our clients reduce their operational costs and environmental footprint.
High-Quality Component Sourcing
We build our machines to last. This is achieved by using reliable, high-quality main components sourced from internationally recognized brands. This philosophy minimizes maintenance requirements and maximizes operational uptime for our customers.

Frequently Asked Questions (FAQ)
1. What types of bags can be used with this machine?
The system is designed for pre-made, open-mouth bags, such as woven polypropylene (PP) bags, paper bags, and poly-lined bags.
2. How is the machine operated? Is it fully automatic?
This is a semi-automatic machine, which offers a great balance of speed and control. The operator simply places an empty bag on the filling spout; the machine then automatically weighs the material, fills the bag, and conveys it to the sewing station for an automated stitched closure.
3. Can the packing weight be easily changed?
Yes, the target weight can be changed quickly and easily through the digital controller's user-friendly interface. The machine supports a wide weighing range from 5kg to 50kg.
4. What is included with the machine purchase?
The standard package includes the main packing scale with its hopper and controls, an industrial bag sewing machine head mounted on a column, and a 2.2-meter screw-type lifting conveyor for filled bags.
5. What kind of maintenance is required?
Routine maintenance is minimal and includes regular cleaning, checking pneumatic connections, and ensuring the sewing machine is properly oiled and threaded. We provide a full manual with detailed maintenance schedules.
