[0028] See also Figure 1-Figure 3As shown, a feeding mechanism of the utility model includes a silo 1 capable of placing at least one stack of materials, and also includes a material dividing component 2 and a material discharging component 3. A material dropping port (not shown) is provided at the bottom end of the silo 1. The material dividing component 2 and the material discharging component 3 are respectively installed on the outside of the silo 1, and the material dividing component 2 includes a material dividing plug-in and a first driving component for driving the material dividing plug-in to extend and retract laterally, and the material discharging component 3 includes a material discharging plug-in and a second driving component for driving the material discharging plug-in to extend and retract laterally. When the material dividing plug-in is extended, it holds the material above it and separates the material below it, and when the material dividing plug-in is retracted, it puts down the material. The material discharging plug-in is located below the material dividing plug-in, and the distance between the material discharging plug-in and the material dividing plug-in is approximately the height of one material, so that one material can be loaded at a time, but it is not limited to this. In other embodiments, the distance between the material discharging plug-in and the material dividing plug-in can be increased according to actual needs, so that at least two materials can be loaded at a time. The discharge plug-in holds the material placed by the material distribution plug-in or the material separated by the material distribution plug-in when it is extended, and puts down the material separated by the material distribution plug-in when it is retracted, so that the material separated by the material distribution plug-in falls from the drop-out opening of the silo 1.

[0029] In the present embodiment, the first driving member is a material dividing cylinder 22, which is installed on the outer side of the bottom of the silo 1 by a first fixed bracket 4, and its piston rod extends inwardly from the silo 1, and is connected to a material dividing plug-in. The second driving member is a material discharging cylinder 32, which is installed on the outer side of the bottom of the silo 1 by a second fixed bracket 5, and its piston rod extends inwardly from the silo 1, and is connected to a material discharging plug-in. In other embodiments, the material dividing cylinder 22 and the material discharging cylinder 32 are replaced by electric push rods or hydraulic cylinders, etc., respectively, which are equivalent replacements. The bottom of the silo 1 is the base 13 of the silo 1, so the first fixed bracket 4 and the second fixed bracket 5 are respectively installed on the outer side of the base 13. The number of bases 13 is specifically two, and the two bases 13 are arranged oppositely and at intervals, and the spacing between the two bases 13 can be adjusted to adapt to battery end plates of different specifications. In addition to the base 13, the silo 1 also includes four corner columns 14. The cross-section of each corner column 14 is L-shaped, two of which are erected at the two ends of one of the bases, and the remaining two corner columns are erected at the two ends of the other base. The four corner columns correspond to the four corners of the battery end plate. Specifically, the first fixed support 4 is provided with a plurality of first mounting holes 41, which cooperate with screws to achieve the installation and fixation of the first fixed bracket 4. Similarly, the second fixed bracket 5 is provided with a plurality of second mounting holes 51, which cooperate with screws to achieve the installation and fixation of the second fixed bracket 5. The first mounting hole 41 and the second mounting hole 51 are waist-shaped holes extending up and down, respectively, so as to adjust the installation position of the first fixed bracket 4 and the second fixed bracket 5 up and down, thereby adjusting the position of the material dividing cylinder 22 and the material discharging cylinder 32 up and down, so as to adapt to materials of different specifications.

[0030] The material distribution plug-in includes at least one material distribution plug-in rod 21. Specifically, in this embodiment, the material distribution plug-in includes a plurality of material distribution plug-in rods 21, and the plurality of material distribution plug-in rods 21 are arranged in parallel in the horizontal direction. The number of the material distribution plug-in rods 21 is specifically two, but not limited thereto. The two material distribution plug-in rods 21 are fixed on a support rod 23, and the support rod 23 is used to connect the piston rod of the material distribution cylinder 22.

[0031] like Figure 3 As shown, the discharge plug-in is a horizontal discharge plug-in plate 31, and one end of the discharge plug-in plate 31 is connected to the piston rod of the discharge cylinder 32.

[0032] In this embodiment, there are multiple material distribution components 2, which are located on different sides of the outside of the silo 1 and on the same level. Figure 1 As shown, there are two material dividing components 2, and the two material dividing components 2 are respectively installed on the left and right sides of the silo 1, specifically, are respectively installed on the two bases 13 of the silo 1. By providing a plurality of material dividing components 2, and making the material dividing plug-ins (i.e., material dividing plug rods 21) of the two material dividing components 2 extend and retract synchronously to jointly support the material, the pressure on each material dividing component 2 can be reduced, which is beneficial to extending the service life of the material dividing component 2. In addition, the length of the material dividing plug-in can be set shorter to make the overall structure more compact, and it is beneficial to increase the extension and retraction speed of the material dividing plug-in, thereby increasing the material dividing speed. Similarly, there are a plurality of material discharging components 3, and the plurality of material discharging components 3 are located on different sides of the outside of the silo 1 and are on the same level. Specifically, as Figure 1 As shown, there are two discharge components 3 , which are respectively installed on the left and right sides of the silo 1 , and specifically, are respectively installed on the two bases 13 of the silo 1 .

[0033] In this embodiment, a feed port 11 is provided at the top of the silo 1 to facilitate the placement of materials. One or more hollow windows are provided on the side wall of the silo 1, so that the material distribution plug-in and the material discharge plug-in can enter and exit the silo 1 through the hollow windows 12 respectively. Specifically, the four side walls of the silo 1 are respectively provided with hollow windows 12, and the upper end and / or lower end of the hollow windows 12 are provided with openings. The intervals between adjacent corner columns 14 constitute the hollow windows 12. The cross-sectional shape and size of the interior of the silo 1 are adapted to the shape and size of the material, so that the silo 1 can provide guidance for the up and down movement of the material.

[0034] A loading mechanism of the utility model can be used for loading battery end plates 6, but is not limited to this. During operation, a whole stack of battery end plates 6 is manually placed into the silo 1. At this time, the material dividing rod 21 is in a retracted state, and the material discharging plug plate 31 is in an extended state, and supports the whole stack of battery end plates 6. During material dividing, the material dividing cylinder 22 is started, driving the material dividing rod 21 to extend into the silo 1, and supporting the second-to-last layer of battery end plates 6, so that the battery end plates 6 at the bottom layer are separated and supported by the material discharging plug plate 31; then, the material discharging cylinder 32 is started, driving the material discharging plug plate 31 to retract, and the material discharging plug plate 31 puts down the battery end plates 6 at the bottom layer, and makes the battery end plates 6 at the bottom layer fall from the discharging port of the silo 1. Then, the material discharging plug plate 31 is extended again, and the material dividing cylinder 22 is started, driving the material dividing rod 21 to retract, so that the remaining whole stack of battery end plates 6 falls onto the material discharging plug plate 31. This reciprocating cycle is repeated until the silo 1 is emptied. Therefore, the utility model provides a new type of feeding method, which has the characteristics of simple structure, low cost, small space occupation, fast feeding speed, etc.

[0035] See also Figure 1-Figure 4 As shown, a feeding device of the utility model comprises a conveying line 7 for conveying materials and at least one feeding mechanism of the utility model as described above. The base 13 of the silo 1 is installed on the conveying line 7 so that the materials falling from the drop port fall onto the conveying line 7.

[0036] In this embodiment, there are multiple feeding mechanisms, which are distributed along the conveying direction of the conveyor line 7. Specifically, there are three feeding mechanisms, but this is not limited to this. Multiple feeding mechanisms can be arranged close together or separately, and can be set according to actual needs, so as to achieve flexible control of the feeding speed.

[0037] During operation, the battery end plate 6 dropped from the material drop opening of the silo 1 falls onto the conveyor line 7, and the conveyor line 7 conveys the battery end plate 6 to the material position to be taken. After the previous silo 1 is emptied, it switches to the next silo 1 to continue working, and reminds manual refilling, so as to realize non-stop loading.

[0038] The utility model provides a feeding mechanism and a feeding device, and the unrelated parts are the same as the prior art or can be implemented by using the prior art.

[0039] The above embodiments are only used to further illustrate a feeding mechanism and a feeding device of the utility model, but the utility model is not limited to the embodiments.
