Operating Process
  • Operators place empty containers onto the mesh conveyor, which can buffer 30-40 empty containers.
  • Jerrycan: The container passes through a turning and air-blowing station. A vacuum suction cup grips the jerrycan and flips it backward. An air nozzle inserts into the container bottom for purging and cleaning.
    Drum: The drum reaches the decapping station. Mechanical positioning aligns the drum. A pneumatic gripper descends, and a servo motor rotates the gripper to loosen the cap. Removed caps are transferred to a cap conveyor.
  • Four empty containers (jerrycans or drums) enter the filling station as one group. Each filling position is equipped with a roller conveyor weighing platform with a maximum capacity of 50kg.
  • A photoelectric sensor detects container positioning. The filling lance descends into the bunghole.
  • The bottom valve opens, followed by the inlet valve. Filling begins with coarse filling, then switches to fine filling. The filling lance gradually rises as the liquid level increases until the preset weight is reached.
  • The filling lance retracts. Filled containers exit the station, and the next batch of four empty containers enters.
  • Jerrycan: Arrives at the capping station where automatic screw capping is completed.
  • Drum: Arrives at the internal cap station. A vision system corrects alignment before internal cap tightening. The drum then proceeds to the external lid pressing station.
  • Four filled containers enter the tilt-type leak inspection station to check for leakage around the opening.
  • A robot palletizes the containers one by one until a full pallet is completed.
  • The finished pallet enters the stretch wrapping station, followed by horizontal and vertical strapping stations.
