Automatic big open mouth bag Packaging Machine

What is Automatic big open mouth bag Packaging Machine?

Automatic big open mouth bag Packaging Machines are industrial equipment used for bulk material metering and bagging. They are suitable for filling powdery or granular materials into pre-formed open mouth bags, such as cement, fertilizer, feed, or plastic granules, commonly in 25 kg to 50 kg bag scenarios. During operation, empty bags are manually or via a conveyor to the clamping position. The weighing module feeds the material into the bag in batches according to a set weight. The feeding speed can be adjusted according to the material's flowability to reduce jamming or spillage.

The machine typically consists of a weighing unit, a material conveying structure, a bag clamping mechanism, and a subsequent sewing or heat-sealing device. Some production lines are also connected to palletizing equipment for convenient subsequent stacking and transportation. In some production workshops, these open mouth bag packaging machines can switch between different packaging sizes. The operating interface generally uses a PLC touch screen, making parameter settings intuitive and suitable for switching between different materials.

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

In an automatic large open mouth bag packaging machine for bulk granular materials, the operator places the bag at the discharge port, the clamping mechanism secures the bag opening, and the material enters the weighing hopper and is gradually fed according to the set weight. Once the set weight is reached, feeding stops, and the bag is released and conveyed by the conveyor to the sewing or heat-sealing station to complete the sealing process.

What are the features of the Automatic Big Open Mouth Bag Packaging Machine?

The Automatic Big Open Mouth Bag Packaging Machine can achieve weighing control within ±0.2%–0.5% range, supports bag weight from 10kg to 50kg and can be adjusted as needed. Combined with a continuous feeding filling mechanism, it can improve the bagging speed. It is suitable for use in production lines for cement powder, feed pellets, etc. It can operate fully automatically or switch to semi-automatic operation mode. The stainless steel or carbon steel structure makes it easy to integrate into the packaging production line.

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.

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.

What are the uses of the Automatic Big Open Mouth Bag Packaging Machine?

Automatic big open mouth bag packaging machines are commonly used in grain processing, feed production, and pellet material filling. They can be used for ton bag metering, bagging, and sealing of bulk materials such as rice, flour, and nuts. They are also suitable for quantitative packaging of industrial raw materials such as fertilizers, plastic granules, cement, and tile adhesive powder. They can complete continuous bagging and transfer in building materials, agricultural seeds, and organic fertilizer feeding lines, facilitating warehousing and logistics turnover.

Automatic big open mouth bag Packaging Machine Applicable bag types

Automatic big open mouth bag Packaging Machine is compatible with a variety of large open bags, including woven bags made of PP/PE materials, which are commonly used for fertilizer and feed packaging, paper bags made of multi-layer kraft paper, which are used in food or environmental protection fields, sacks made of natural fibers, suitable for agricultural product storage, and composite bags made of aluminum-plastic or plastic-woven composite materials, which are used for moisture-proof and anti-oxidation material packaging.
