What is the Fully Automatic Bagging Line?

The auger automatic bagging line is our most complete and highest automation packaging equipment. The whole set of equipment is used to pack powder-type materials, which realizes 100% machine automation, does not require manual participation at all, and provides excellent bagging accuracy and self-detection and correction capabilities, which greatly improves production efficiency and reduces labor costs.

The worker places the pre-formed open-mouth bags at the designated position, and the machine uses the suction cup to automatically put the bag on the outlet of the silo. Then the servo motor controls the vertical auger to feed the material into the bag. When the weight of the bag reaches the preset value, the gripper will send the bag to the automatic sewing machine for sealing, and then enter the steps of shaping, weight detection, metal detection, rejection, etc., and finally palletizing by palletizing robots. The trays are then packed by the pallet wrapping machine, completing the entire packaging process.

The whole bagging system is controlled by the computer program, with simple operation, complete functions, reasonable maintenance, accurate weighing, ensuring material hygiene, greatly improving packaging efficiency, and reducing environmental pollution.

  1. Automatic bagging, bagging, metering, sealing and conveying.
  2. The modular design allows flexible adjustment of the packaging line according to customer requirements.
  3. All machines are equipped with anti-jamming technology and high precision weighing modules for accurate and reliable weighing data.
  4. The entire line can be equipped with weight detection, metal detection and rejection systems to ensure that the products are qualified.
  5. The palletizing process can be carried out by robots in the post-process to improve efficiency.
  6. PLC control, automatic operation, high production efficiency, low failure rate and smooth operation.



The use of parts from internationally renowned brands and adapt common standards increases the stability of the equipment and reduces the risk of not being able to find replacement parts in the future.

Wxtytech does the same, all from the point of view of a good customer experience.
