[0034] According to some embodiments of the present application, please refer to Figures 1 to 5 , this embodiment relates to an automatic filling mechanism for packaging a special binder for battery cells, including a feeding device 1, a conveying device 2, and a weighing device 3. The feeding device 1 includes a vibrating feeder 11, a vibrating motor 12, a feeding pipe 13, a lifting cylinder 14, a gland 15, and a flap valve 16. The vibrating feeder 11 is electrically connected to the vibrating motor 12. The vibrating feeder 11 is provided with a feeding port for feeding. The feeding pipe 13 is connected to the vibrating feeder 11. The lifting cylinder 14 is installed inside the feeding pipe 13. The gland 15 is located at the bottom of the feeding pipe 13. The gland 15 is connected to the lifting cylinder 14. The flap valve 16 is located at the bottom of the lifting cylinder 14. The flap valve 16 is used to open or close the material conveying channel. The conveying device 2 is located below the feeding device 1. The conveying device 2 includes a conveying table 21, an empty barrel 22, and a motor 23. The motor 23 is located inside the conveying table 21. The conveying table 21 is electrically connected to the motor 23. The conveying table 21 is used to convey the empty barrel 22. The empty barrel 22 is used to dock with the gland 15 and receive the material. The weighing module 37 is located inside the conveying table 21. The weighing module 37 is used to weigh the material inside the empty barrel 22.

[0035] During use, the conveying table 21 is driven by the motor 23 to transport the empty barrel 22 to the designated position. At the same time, the lifting cylinder 14 drives the capping head 15 to extend. When filling, the flap valve 16 is opened, and the material falls through the feeding port to the vibrating feeder 11. The vibrating feeder 11 vibrates the material to the blanking pipe 13 and finally transports it into the empty barrel 22. During the filling process, the vibration frequency of the vibrating feeder 11 can be adjusted by setting the weight range through the PLC to achieve fast filling, medium filling, and slow filling when almost full. During transportation, the weighing module 37 will be calibrated. After reaching the fixed quantity, the PLC gives a signal indicating that the filling is completed, and the process ends.

[0036] According to some embodiments of the present application, optionally, a corrugated flexible connection 17 is provided around the lifting cylinder 14, and the bottom of the corrugated flexible connection 17 is connected to the top of the capping head 15.

[0037] In this way, it is convenient for the lifting cylinder 14 to expand and contract, driving the capping head 15 to move up and down. The corrugated flexible connection 17 is installed around the lifting cylinder 14. When the lifting cylinder 14 expands and contracts in the vertical direction, the corrugated flexible connection 17 provides a buffering force, making the expansion and contraction of the lifting cylinder 14 smoother.

[0038] According to some embodiments of the present application, optionally, the blanking device 1 further includes a buffer bin 18. The buffer bin 18 is located above the vibrating feeder 11. A blanking port 181 is provided at the bottom of the buffer bin 18, and the blanking port 181 is connected to the feeding port.

[0039] In this way, the material can be stored in the buffer bin 18 and enter the vibrating feeder 11 through the blanking port 181 at the bottom of the buffer bin 18. The vibrating motor 12 drives the vibrating feeder 11 to discharge the material. The buffer bin 18 has a certain storage space, and at the same time, the blanking port 181 of the buffer bin 18 matches the feeding port of the vibrating feeder 11, realizing the automation of putting the material into the vibrating feeder 11 and reducing manual operation.

[0040] In some embodiments, the buffer bin 18 is funnel-shaped, with a large upper part and a small lower part. The blanking port 181 at the bottom is the funnel opening. A feeding port is provided at the top of the buffer bin 18, and the staff adds materials from the top of the buffer bin 18. The funnel shape causes the material to accumulate at the blanking port 181 under the action of gravity, facilitating the transfer of the material to the vibrating feeder 11. In some embodiments, the buffer bin 18 is movably connected to the vibrating feeder 11, and the staff can select buffer bins 18 of different specifications according to requirements to appropriately store corresponding amounts of materials.

[0041] According to some embodiments of the present application, optionally, a level gauge 182 is provided at the top of the buffer bin 18, and the level gauge 182 is used to measure the height of the material in the buffer bin 18.

[0042] In this way, it is convenient to measure the height of the material in the buffer bin 18 by observing the value of the level gauge 182. When the level gauge 182 indicates that the height of the material in the buffer bin 18 is low, the staff immediately adds material to the buffer bin 18 to prevent the interruption of material discharging and improve the material discharging efficiency.

[0043] According to some embodiments of the present application, optionally, a vibrator 183 is provided on the buffer bin 18, and the vibrator 183 is electrically connected to the vibration motor 12.

[0044] In this way, the vibrator 183 can make the material in the buffer bin 18 obtain a certain form and magnitude of vibration, thereby accelerating the vibration of the material and enabling the material to enter the vibrating feeder 11 from the buffer bin 18 more efficiently.

[0045] According to some embodiments of the present application, optionally, the weighing device 3 includes a first roller 31, a second roller 32, a cylinder 33, a connecting plate 34, and a weighing module 37. The cylinder 33 is located at the bottom of the connecting plate 34, the weighing module 37 is installed on the connecting plate 34, the weighing module 37 is used to weigh the empty barrel 22, the first roller 31 and the second roller 32 are installed on both sides of the connecting plate 34, and the cylinder 33 is used to drive the weighing module 37 and the empty barrel 22 to move up and down.

[0046] In this way, when the empty barrel 22 reaches the designated position, the cylinder 33 drives the weighing module 37, the first roller 31, the second roller 32, and the connecting plate 34 to descend as a whole. At this time, the bottom of the empty barrel 22 leaves the surface of the roller, the weighing module 37 measures the tare weight of the empty barrel 22 and resets to zero after peeling. After adding materials, the materials in the empty barrel 22 are weighed.

[0047] According to some embodiments of the present application, optionally, the weighing module 37 further includes a weighing module support 36 and an empty barrel plate 35. The weighing module support 36 is installed below the weighing module 37, the weighing module support 36 is used to fix the weighing module 37, the empty barrel plate 35 is located above the weighing module 37, and the empty barrel plate 35 is used to receive the empty barrel 22.

[0048] In this way, it is convenient to fix the weighing module 37 on the weighing module support 36. The empty barrel 22 is placed on the empty barrel plate 35, and the weighing module 37 weighs the empty barrel 22.

[0049] According to some embodiments of the present application, optionally, the conveying table 21 includes a roller conveyor belt 211, a position inductor 212, and a stopper 213. The motor 23 is electrically connected to the roller conveyor belt 211. The position inductor 212 and the stopper 213 are provided on the roller conveyor belt 211. The position inductor 212 is electrically connected to the motor 23, the stopper 213 is electrically connected to the position inductor 212, and the stopper 213 is installed on one side of the first roller 31.

[0050] In this way, it is convenient to transport the empty barrel 22 through the roller conveyor belt 211. When the in-place sensor 212 senses that the empty barrel 22 is transported to the designated position, the stopper 213 rises to limit the empty barrel 22 in a certain position, facilitating blanking and weighing.

[0051] The empty barrel 22 is placed on the roller conveyor belt 211. When the in-place detection switch detects that the empty barrel 22 is in place, the stopper 213 rises, and the empty barrel 22 reaches the filling position. The motor 23 stops rotating, and the cylinder 33 descends to drive the roller motor 23 to descend as a whole. At this time, the bottom of the empty barrel 22 leaves the roller surface and sits on the barrel receiving plate. The capping 15 cylinder 33 extends to drive the capping 15 to press onto the barrel mouth. The weighing module 37 measures the tare weight at this time, and the PLC automatically controls the weighing module 37 to tare and zero. The flap valve 16 opens, and the vibration motor 12 starts to work. The material enters the vibrating feeder 11 through the blanking port 181. The PLC controls the vibration frequency of the vibration motor 12 to achieve fast feeding, medium feeding, and slow feeding. When the target filling value is reached, the PLC controls the following: the lifting cylinder 14 retracts to drive the capping 15 to leave the barrel surface, the cylinder 33 rises to drive the roller back to the bottom of the barrel, the stopper 213 descends, the motor 23 starts to rotate, and the roller drives the barrel to leave the filling position, and the filling is completed.

The feeding device 1 realizes fast feeding, medium feeding, and slow feeding through the vibration frequency of the vibrating feeder 11. The lifting cylinder 14 is provided in the feeding pipe 13. The feeding device 1 is driven to descend by the lifting cylinder 14 to open the flap valve 16, so that the empty barrel 22 can be hermetically docked with the feeding device 1 to prevent powder leakage and avoid material extrusion at the same time.
