The driving mechanism 221 of the stirring assembly 22 is provided with a long spiral structure 222, and the long spiral structure 222 is rotationally fed in a pipeline channel between the upper degassing part 27 and the lower discharging part 23 through the driving mechanism 221.

After the powder of the vertical feeding component 20 is temporarily stored in the blanking bin 21, the precise feeding is carried out through the stirring component 22 and the long spiral structure 222 with variable screw pitch, and the outlet at the tail end is provided with a leakage-proof mechanism. Including but not limited to a foot valve drive member 25, a sliding sleeve 24, and a leak-proof foot valve 26. The sliding sleeve 24 is mounted on the bottom valve driving part 25 for follow-up, and the leakage-proof bottom valve 26 is mounted at the bottom of the lower discharging part 23 and adopts a detachable anti-loosening structure, thereby replacing the existing structure which is mounted at the bottom of the long spiral structure 222 and is rotated with the long spiral structure and is easy to loosen.

The bottom valve sealing material is of a split type design, easily-damaged parts can be replaced, and the use cost of a user is saved.

Preferably, the bag hanging mechanism assembly 50 includes a plurality of high precision weighing modules 51 (e.g., C10 high precision weighing modules), a lift bag hanging rack 52, a weighing rack 53, a plurality of hanger modules 54, an airbag bag clamping assembly 55, a bag clamping airbag swing mechanism 56, and a plurality of hanger swing arm mechanisms 57.

Wherein the high-precision weighing module 51 is mounted on the lifting bag hanging rack 52. The weighing bracket 53 is installed on the high-precision weighing module 51, and the hook module 54 is installed on the weighing bracket 53 for realizing high-precision weighing.

One end of the hook module 54 is connected to the bag lifting and hanging frame 52, and the other end is connected to and follows the corresponding hook swing arm mechanism 57, so that the hook module 54 swings to one side.

The bag hanging mechanism assembly 50 is configured in a swinging type, so that an operator of the operation surface can perform a bag hanging function in situ after the mechanism swings to a proper position, for example, the operation distance between two adjacent hook swinging arm mechanisms is reduced from about 1400mm to about 450mm, and is variable in the range. This avoids the need for personnel to run onto the ton bag conveyor 61 for operation and thereby create a constant or increased risk of accident.

Further, the lifting driving assembly 40 comprises a driving part 41 and a lifting part 42, the driving part 41 is installed on the maintenance platform 11, and the lifting part 42 is connected with the bag hanging mechanism assembly 50 to meet the packaging requirements of different bag heights.

In addition, a self-centering lock pin 28 is arranged at the joint of the bottom feed opening of the blanking bin 21 and the upper degassing part 27, and the self-centering lock pin 28 prevents rotation and locking.

The materials are stirred uniformly by the stirring component 22 in the blanking bin 21 to prepare blanking. The system starts the blanking process, the bottom valve driving part 25 drives the sliding sleeve 24 to slide upwards, so that the sliding sleeve 24 is separated from the leakage-proof bottom valve 26 to form a discharge hole (shown in fig. 6). The long spiral 222 starts and rotates and material is discharged by the spiral and is degassed by the upper degassing section 27, while the self-centering locking pin 28 keeps the upper degassing section 27 from following the long spiral 222. The material enters the lower discharging part 23 along with the long spiral structure 222 after being degassed, and finally falls into a packaging bag through a discharging hole opened between the sliding sleeve 24 and the leakage-proof bottom valve 26. After the packaging amount reaches the target value, the long spiral structure 222 stops rotating, and the bottom valve driving part 25 drives the sliding sleeve 24 to slide downwards, so that the sliding sleeve 24 and the leakage-proof bottom valve 26 are closed, and the system is ensured not to leak after being closed.

When the equipment starts to work after being started, the hook module 54 and the air bag clamping assembly 55 swing to a manual operation position, and the packaging is started after the bag is hung manually. The mechanism resets, and the gasbag presss from both sides the bag and starts simultaneously, and the sack seals.

The stirring component 22 and the long spiral structure 222 in the lower bin 21 are sequentially started, the bottom valve driving part 25 drives the sliding sleeve 24, and the leakage-proof bottom valve 26 is opened for feeding. The lifting drive assembly 40 descends to the ton bag conveyor 61 according to the material feeding condition, and the system starts the vibration platform 62 to tap. After the vertical feed assembly 20 is fed and metered, the lift drive assembly 40 is lowered and the ton bag is lowered onto the ton bag conveyor 61. The hook module 54 and the air bag clamping assembly 55 swing to a manual operation position, meanwhile, the air bag clamping is exhausted and reset, and the ton bag 70 is taken down manually to be hung and the bag mouth is tightened. The ton bag conveyor 61 is started to convey the finished ton bags out of the equipment after packaging.
