Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.
[0032] like Figure 1-Figure 6 As shown:
[0033] The crucible charging device provided in one embodiment of the application comprises a support 1, on which a hopper 2 is fixedly mounted, a lower end of the hopper 2 is fixedly connected to a feeding pipe 3, and a lower end of the feeding pipe 3 is fixedly connected to a telescopic pipe 4. Specifically, the telescopic pipe 4 is a rubber bellows.
[0034] In this embodiment, a feeding port (not shown) is set at the top of the hopper 2.
[0035] The lower end of the telescopic tube 4 is fixedly connected with a compacting device 5 which can load and compact the crucible 7 .
[0036] The compacting device 5 is connected to a lifting device which can drive it to move up and down.
[0037] When in use, the crucible 7 is first transferred to the bottom of the compacting device 5, and then the compacting device 5 is moved down to the inside of the crucible 7, and the negative electrode material in the hopper 2 is filled into the crucible 7 through the compacting device 5. When the crucible 7 is filled with a certain amount of negative electrode material, the loading work is stopped, and the compacting device 5 is moved down. The lower end of the compacting device 5 compacts the negative electrode material. After the compaction is completed, the compacting device 5 is moved up a certain distance. After the compacting device 5 continues to fill a certain amount of negative electrode material into the crucible 7, the loading work is stopped again, and the compacting device 5 is moved down to compact the negative electrode material again. In this way, the loading work of the crucible 7 can be completed through multiple small-scale loading and compacting operations.
[0038] The crucible charging device provided in the present embodiment has a hopper 2 installed on a bracket 1, the lower end of the hopper 2 is connected to a feeding pipe 3, the lower end of the feeding pipe 3 is connected to a telescopic tube 4, the lower end of the telescopic tube 4 is connected to a compacting device 5 capable of charging and pressing the crucible 7, the compacting device 5 is connected to a lifting device capable of driving it to move up and down, so that when the crucible 7 is charged, the negative electrode material can be compacted in sections through multiple small amounts of charging and compacting operations, which not only improves the uniformity of the compaction of the negative electrode material and the compaction effect, but also can increase the charging amount of each crucible 7.
[0039] In some embodiments of the present application, the compacting device 5 includes a pressing plate 51, a material guide tube 52 is fixed at the middle of the upper end of the pressing plate 51, and a plurality of material discharge ports 53 are formed on the pressing plate 51 and are distributed in an annular shape and are located in the material guide tube 52. Specifically, the material discharge ports 53 are fan-shaped structures. A material blocking structure 54 that can open or close the material discharge ports 53 is provided at the lower end of the pressing plate 51.
[0040] The upper end of the material guiding tube 52 is fixedly connected to the lower end of the telescopic tube 4 , and the lifting device is connected to the pressing plate 51 .
[0041] When in use, when the crucible 7 is located below the pressing plate 51, the lifting device drives the pressing plate 51 to move down into the crucible 7, and then the blocking structure 54 is operated to open all the discharge ports 53, and the negative electrode material in the hopper 2 passes through the discharge pipe 3, the telescopic tube 4, the guide pipe 52 and the discharge port 53 and falls into the crucible 7 in turn. When the crucible 7 is filled with a certain amount of negative electrode material, the blocking structure 54 is operated, and the blocking structure 54 closes all the discharge ports 53, stops the loading work, and then continues to move the pressing plate 51 down. After the pressing plate 51 moves down, the pressing plate 51 and the blocking structure 54 apply pressure to the negative electrode material in the crucible 7 to compact the negative electrode material. After the compaction is completed, the pressing plate 51 is moved up a certain distance, and then the discharge port 53 is opened again for loading. After a certain amount of negative electrode material is filled into the crucible 7 again, the pressing plate 51 is moved down again for compaction. This cyclic operation completes the loading work of the crucible 7.
[0042] In some embodiments of the present application, the material guide tube 52 is a truncated cone structure, the large diameter end of the material guide tube 52 is fixedly connected to the pressure plate 51, and the small diameter end of the material guide tube 52 is fixedly connected to the telescopic tube 4, thereby increasing the size of the discharge port 53 to improve the loading efficiency.

Specifically, the material blocking plate 541 is located at the lower end of the pressing plate 51, and the upper end of the material blocking plate 541 contacts the lower end of the pressing plate 51. The material blocking plate 541 is connected to a driving device 55 capable of driving the same to rotate.
[0044] When in use, after rotating the baffle plate 541, when each discharge hole 542 overlaps with the corresponding discharge port 53, the discharge port 53 is in an open state; when the discharge hole 542 moves to the side of the discharge port 53 and does not overlap with the discharge hole 542, the discharge port 53 is in a closed state.

Then, after the material baffle plate 541 moves up and down with the pressing plate 51, the reduction motor 551 fixed on the upper end of the hopper 2 can smoothly drive the material baffle plate 541 to rotate. Moreover, after the telescopic shaft 552 rotates, the discharge port of the hopper 2 and the feeding tube 3 can be prevented from being blocked.

The upper end of the second shaft body 554 is fixedly connected to the output shaft of the reduction motor 551. The lower end of the first shaft body 553 is fixed with a connecting shaft 555 of a cylindrical structure. The connecting shaft 555 penetrates the pressing plate 51 and is rotatably connected to the pressing plate 51 through a bearing. The connecting shaft 555 is fixedly connected to the upper end of the material blocking plate 541.

[0048] Furthermore, a mounting sleeve is fixedly mounted on the hydraulic cylinder, and the mounting sleeve is fixedly connected to the outer wall of the feeding pipe 3 .
[0049] When in use, the two hydraulic cylinders extend and retract synchronously. When the hydraulic cylinders extend, the pressing plate 51 moves downward; when the hydraulic cylinders shorten, the pressing plate 51 moves upward.
