automatic bagging machine
Due to the different occasions, industries, weighing ranges, and accuracy requirements, automatic bag machine have their own specificity. Different types of auto bagging system have their own unique structures to suit certain specific requirements.
- According application: feed bagging machine, wood pellet bagging machine, sawdust bagging machine, corn bagging machine, grain packing machine, flour bagging machine, etc.
- Feeding forms include funnel type, double cylinder screw type, single cylinder double speed screw type, scraper type, belt type, etc.;
- The form of bag clamping is similar, and pneumatic actuators are generally used to complete various actions.
Users who use auto bagging machines generally produce pellets or ordinary powdered feed for livestock, aquatic products, and pets, or manufacturers of iodized salt, washing powder, white sugar, monosodium glutamate, seeds, rice and other products. Spiral or scraper feeding is easy to break the particles and have pulsation. Funnel feeding is easy to cause the powder with poor fluidity to form arches, resulting in uneven material flow and affecting the feeding speed and accuracy. Therefore, most manufacturers use a belt feeder that can achieve high-speed and stable feeding.
Features of automatic bagger
At present, automatic bagging machine has been widely used in feed and other industries. Compared with manual weighing and packaging, automatic bagger has the characteristics of fast weighing speed, high weighing accuracy, labor saving, labor saving, simple operation and convenient maintenance, which can greatly improve the reputation and economic benefits of feed companies.
- Fast and slow feeding and quantitative, bag clamping and bag unloading are all controlled by PLC program, and can also be directly controlled by microcomputer intelligently.
- Microcomputer intelligent control instrument can realize the setting of parameters such as fast and slow feeding amount, out-of-tolerance and overload alarm display, and can be equipped with print output;
- The automatic bagging machine has the characteristics of simple structure, convenient matching and moderate price. Its weighing range is within 10-50 kg, and the discharge speed and accuracy are high. For example, for the packaging of pelleted livestock feed, calculated in 40 kg bags, the discharge speed can be as high as 6 to 8 bags/min, and the accuracy is within the range of +(-) 0.2% (less than the standard accuracy of 0.5), so accepted by most feed manufacturers.
- The automated bagging machine can change the feeding form according to the physical characteristics of different materials to achieve the required packaging speed and accuracy.
- Fast weighing speed and high precision; digital display, intuitive and easy to read, stable and reliable, and easy to maintain.
- Can adopt corresponding application technology according to different materials. If there are waterproof type, fragile object type, easy loose object type, mixed weighing, quantity weighing, etc., it can be applied to various needs;
The main factors we consider when designing automatic weighing and bagging machine are the particle size, bulk density, scatterability, fluidity, hygroscopicity, adhesion and other properties of the materials being weighed, which determine the diversity of bagging machine structures.
The classification of automatic packing machine is also often distinguished according to its structural form, that is, according to the adaptability of materials. In addition, they are also classified according to the size of the packaging. Because of different packaging volumes, the selection of sensors, bag clamping mechanisms and packaging forms are different.

structure of automatic bagging machine
The auto bagging machine is mainly composed of a belt feeder, a self-unloading scale hopper, a bag receiving hopper, and an electric control device.
The belt feeder is composed of material layer gate, conveyor belt, switch gate, etc. The conveyor belt is driven by a two-speed motor, and the material layer gate and the opening and closing gate are driven by air cylinders. The feeding amount is controlled by changing the conveying speed of the conveyor belt and controlling the height of the material layer at the discharge port through the two-speed motor. Each weighing process is composed of large and small feeds.
First, the large feed is fed, and then the small feed is fed, and the small feed has a stable process of 1 to 2 seconds to ensure the accuracy of the weighing. Referring to the application of the same type of automatic bagging machine at home and abroad, RICHI designed a belt feeder with a feeding amount of 50 t/h and 5 t/h respectively, that is, the ratio of large feeding amount to small feeding amount is at most 50 t/h and 5 t/h, and can be adjusted according to actual production needs.

Taking the weighing of 40 kg/bag as an example, choose a feeding ratio of 7:1, that is, the large feeding is 35 kg, the small feeding is 5 kg, and the weighing process is completed within 6 s. A switch gate is also set at the outlet of the feeder, which can cut off the material flow in time at the end of feeding to ensure the accuracy of measurement.
Dump scale bucket
The scale bucket and the weighing sensor are connected through a joint bearing or a cylindrical pin, so that the quality of the scale bucket and the material contained can be accurately displayed on the weighing instrument. The discharge door at the bottom of the scale bucket is driven by a single cylinder, and the two doors can move symmetrically with a link mechanism, so that the scale bucket can maintain relative balance during the whole working process of auto bagging system; The material of the bucket is concentrated in the middle of the bottom, which is beneficial to keep the balance of the weighing bucket.
The mouth of the bag is made into a round or oval shape, which can ensure the airtightness after the bag is clamped. Equipped with at least 2 front and rear clamping arms, used to clamp the bag at the mouth of the clamping bag. The outlet is also an exhaust port, so that the dust generated during charging and the air in the bag can be discharged in time, which greatly improves the air environment of the operating surface.

Electronic control device
The key component of this part is the weighing controller. In addition to the functions of coarse measurement, fine measurement, overshoot compensation and discharge control, it also has a high conversion rate (more than 50 times/s), out-of-tolerance detection and Functions such as preset ingredient amount power-off protection.
With the development of the feed industry, the degree of automation of feed mills is getting higher and higher, and the number of feed mills that use manual weighing and packaging has gradually decreased. Instead, microcomputer-controlled automatic bagging machines are used for weighing and packaging, which greatly improves The work efficiency is reduced, the labor intensity is reduced, the weighing accuracy is ensured, and the manual operating environment is improved.
Working principle of automatic bagging machine
—— RICHI MACHINERY ——
When the automatic industrial bagging machine enters the automatic operation state, the weighing control system opens the feeding door and starts feeding. The feeding device adopts the fast and slow two-stage feeding mode; when the material weight reaches the fast feeding set value, the fast feeding is stopped, keep feeding slowly; when the weight of the material reaches the final set value, close the feeding door to complete the dynamic weighing process.
At this time, the system detects whether the bag clamping device is in a predetermined state, and when the packaging bag is clamped, the system sends out The control signal opens the discharge door of the weighing hopper, the material enters the packaging bag, and the discharge door of the weighing hopper is automatically closed after the material is discharged; after the material is unloaded, the bag clamping device is released, and the packaging bag automatically falls; The bag is sewn and transported to the next station, and the cycle runs automatically.
