The first suction nozzle 1001 and the second suction nozzle 1002 are both connected to the external air pump through a straw. The first suction nozzle 1001 is started to generate an adsorption force to suck the packaging bag. The first rotating head 1004 rotates the first suction nozzle 1001 so that the packaging bag is close to the second suction nozzle 1002. The second suction nozzle 1002 is started to generate an adsorption force to suck the packaging bag. The robotic arm 1003 drives the first suction nozzle 1001 away from the second suction nozzle 1002, thereby pulling the packaging bag open. At this time, the expansion structure starts to work to expand the packaging bag.

[0033] In one embodiment of the present invention, the expansion structure includes a third telescopic rod 1006, a connecting block 1007 and two fourth telescopic rods 1008.

The bag sealing head 901 is used to seal the filled packaging bags, and the clamping device 902 is used to move the filled packaging bags to the bag sealing head 901 for sealing.

[0036] The working principle of a fully automatic bag filling system in the present invention is as follows:

[0037] The staff puts the crops into the dust suction device 6, and the dust suction device 6 cleans the dust and garbage in the crops and then sends them into the discharge hopper 102 of the feed bin 1. The discharge hopper 102 is connected to the bottom of the feed elevator 2. The driving wheel 202 and the driven wheel 203 rotate the synchronous belt 204 and drive the transport hopper 205 to rotate along the base frame 201, and lift the crops at the bottom of the base frame 201 to the top of the base frame 201 for output. The feed elevator 2 can send the crops into the warehouse 3 or the bag filling machine 5 through the pipeline. When the number of crops is large and the bag filling machine 5 cannot be cleaned up in time, the feed elevator 2 can send part of the crops into the warehouse 3 for storage. When the number of crops is small, the feed elevator 2 can send the crops into the bag filling machine 5 through the pipeline for bag filling and sealing operations. At the same time, the discharge elevator 4 can also send the crops stored in the warehouse 3 into the bag filling machine 5 through the conveyor belt 301 for bag filling and sealing operations.

[0038] After the crops enter the bag filling machine 5, the bag-opening device 10 starts to absorb a bag from the bag supply device 11, and the absorption structure and the opening structure cooperate to open the bag. The bag clamping device 7 clamps the opened bag and performs the bag filling operation. After the bag filling is completed, the clamping device 902 clamps the opened bag and moves it to the bag sealing head 901 through the track 802 for bag sealing. After the bag sealing is completed, it is conveyed to the stacking place through the conveying device 8. At this point, the bag filling and sealing work is completed.

[0039] In a fully automatic bag filling system of the present invention, a warehouse 3 is arranged at the output end of a feed elevator 2, and crops that have not been bagged in time can be stored. A conveyor belt 301 and a discharge elevator 4 are arranged to cooperate, and crops stored in the warehouse 3 can be bagged when the workload of the bag filling machine 5 is not large. The feed elevator 2 and the discharge elevator 4 can work at the same time, avoiding the problem that when there are too many crops, they are easily piled up in the elevator and overflow or get stuck in the bag filling machine 5. A large amount of piled crops can also be processed in time, and the crops can be bagged in time to avoid damage caused by being piled up for too long.

[0040] The present invention also provides a bag-holding device 10 and a packaging bag supply device 11 to cooperate, which can automatically absorb the packaging bags and perform bag-holding operations, and transport them to the packaging machine 5 through the track 802 for packaging and sealing operations. The whole process is automated, and the staff only needs to place a large number of packaging bags in the packaging bag supply device 11, which is highly efficient and can save a lot of manpower.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
