Technological Process
Artificial putting bag  Automatic supply, opening and clamping bag Putting exhaust pipe into bag Exhaust
mechanism works to pre discharge air of the bag Automatic feeding by weighing machine The first bag
pumping Holding and shifting bag The second opening , clamping bag and bag pumping Holding and
shifting bag Heat sealing Product output
Main function
1. Weight-lost weigher ( including the feeding screw exhaust mechanism)
It’s suitable for weighing of the powder materials such as starch, milk powder, chemical raw materials, formula and
feed additives etc.
- Single screw feeder driven by the servo motor, and two levels feeding ensure the accuracy.
- Full sealed state is applied to the connection between each part of the machine and the dedusting port reserved.
- Hopper is equipped with forced arch breaking device to prevent the powder overhead.
- Specialized exhaust mechanism is designed to improve the compactness of the material for the special characters of the users’ powder.
- Specialized feeding structure is taken to reduce the material gap.
- Precise control and high accuracy

2. Bag packaging machine
The unit is composed of bag storage, taking and arranging device, feeding manipulator, clamping unload device, bag
holding and shifting device, pocket guide device, vacuum system and control system.
- Suitable for flat plastic bag, paper and plastic syntactic bag
- Detection functions of no bag and entrainment.
- Precision components are sealed design, stable and reliable operation.
- Function of fault self-diagnosis and sound and light alarm. And the door shutdown protection device is also adopted to keep safety.
- Specialized auxiliary exhaust mechanism outside the bag is designed to reduce the opening range of the bag before filling and vent portion air. Reducing the twice mixed chance of powder materials and the air in the bag in the filling process and improving the packaging speed
- Twice exhaust mechanism is designed to improve the pumping speed. When in the second process, patting the bag is taken to avoid the loss of material and the second pollution of the pocket. Save cost and ensure measurement accuracy.
