What is the working principle of the Automatic Big Open Mouth Bag Packaging Machine?

Automatic big open mouth bag Packaging Machine completes the packaging operation through an automated process. First, the empty bag is positioned to the filling station by a conveyor belt or a manipulator. After the sensor detects the position of the bag mouth, the bag clamping device fixes the bag mouth. The material enters the bag through gravity feeding, spiral feeding or vibration feeding, and the weighing system ensures the accurate weight of each bag. After filling, the bag mouth enters the sewing or heat sealing stage. Some models are equipped with automatic folding function to enhance the sealing. Finally, the packaged bag is sent out by the conveyor belt, and the stacking or direct shipment is completed. The whole process does not require manual intervention, which greatly improves production efficiency.

What are the types of Automatic big open mouth bag Packaging Machine?

Automatic big open mouth bag Packaging Machine can be divided into various types according to the degree of automation, functional characteristics and production capacity requirements, suitable for the packaging needs of granular and powder materials in different industries.

Semi-automatic open-mouth bag packaging machine: Suitable for small and medium-sized production enterprises, requires manual bagging, is simple to operate and has low maintenance costs, and has a moderate packaging speed (about 200-400 bags/hour). The basic model costs about $15,000-20,000, which is suitable for budget-limited or low-volume scenarios.

Fully automatic open-mouth bag packaging machine: Integrated automatic bag picking, precision filling, and sealing functions, supports conventional granular materials (such as fertilizers and feed), with an efficiency of 500-800 bags/hour, and a price of about $30,000-50,000. Some models are equipped with a weighing system to improve accuracy.

Servo-driven high-speed packaging machine: It uses servo motor control and is suitable for large-scale production (such as food and chemical industries). The speed is up to 1,000 bags/hour, the error rate is lower, the price is higher ($50,000-80,000), but the long-term capacity return is significant.

Dust-proof packaging machine: designed for dusty powders (such as cement and charcoal powder), equipped with a closed conveying system and dust removal device to prevent material leakage. The price is about US$40,000-60,000, which is suitable for factories with strict environmental protection requirements.
