[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0050] like Figure 2 As shown, the utility model provides a feeding device, comprising: a storage container 1 and a feeding mechanism 2, wherein the storage container 1 has a accommodating cavity 11, and at least one group of nozzle groups 12 located in the accommodating cavity 11, the nozzle group 12 has a plurality of nozzles 121 arranged at intervals along the length direction F of the storage container 1, the nozzle 121 includes an inlet 1211 located in the accommodating cavity 11, and a discharge port 1212 located outside the accommodating cavity 11; the feeding mechanism 2 has a rotating shaft 21 and a plurality of material picking structures 22 connected to the rotating shaft 21 at intervals, the rotating shaft 21 is rotatably connected to the storage container 1; wherein the plurality of the material picking structures 22 have a plurality of material picking spoons with different rotation radii.

[0051] The inventors found that if Figure 1 As shown, if the materials to be added include materials 10 with significantly different particle sizes, the proportion of each material in the added product may be different from the original proportion. Through further analysis and research, it was found that the reason is that various granular materials have a stacking problem, that is, the materials 10 with different particle sizes in the storage container 1 are arranged in layers along the height direction of the storage container 1, resulting in uneven addition of the materials 10.

[0052] The utility model provides a feeding device, which can effectively solve the problem of accumulation of different materials 10 with various particle sizes in a storage container 1, and can solve the problem of uniform addition of materials 10 with various particle sizes.

[0053] Specifically, the storage container 1 has a receiving chamber 11, which is used to store granular materials such as chocolate beans, fruit grains, marshmallows, whole grains, etc., and can also store fluid materials such as liquid materials or slurry materials. The utility model does not limit the type of material 10.

[0054] The nozzle group 12 is located in the accommodating chamber 11. In the present invention, multiple nozzle groups 12 can be provided according to the total amount of material put in and the efficiency of putting in; Figure 3 As shown, for example, two nozzle groups 12 are arranged in the accommodating cavity 11, and the two nozzle groups 12 are arranged at intervals along the width direction E of the storage container 1; of course, if the width of the storage container 1 is wide enough, three or more nozzle groups 12 can also be arranged in the accommodating cavity 11, and there is no limitation here.

[0055] The multiple nozzles 121 in each nozzle group 12 are arranged at intervals at the bottom of the accommodating cavity 11 along the length direction F of the storage container 1, and each nozzle 121 includes an inlet 1211 and an outlet 1212, wherein the inlet 1211 is located in the accommodating cavity 11, and the outlet 1212 is located outside the accommodating cavity 11.

[0056] The feeding mechanism 2 is a structure for feeding materials into each nozzle group 12, and its rotating shaft 21 is rotatably provided through the two side walls of the material storage container 1. In one embodiment, the material storage container 1 has a first side wall 13 and a second side wall 14 arranged opposite to each other, and the rotating shaft 21 has a first end 211 and a second end 212. The first end 211 of the rotating shaft 21 is provided through the first side wall 13 of the material storage container 1, and the second end 212 of the rotating shaft 21 is provided through the second side wall 14 of the material storage container 1, so that the rotating shaft 21 is accommodated in the accommodating cavity 11 of the material storage container 1, and the extending direction of the rotating shaft 21 is consistent with the length direction F of the material storage container 1.

[0057] The multiple material taking structures 22 of the feeding mechanism 2 are connected to the rotating shaft 21 at intervals. When the rotating shaft 21 rotates, each material taking structure 22 rotates, so that the material in the storage container 1 can be turned over, scooped, and placed into each material nozzle 121. In the utility model, the multiple material taking structures 22 have multiple material taking spoons with different rotation radii, so that the material at different depths in the accommodating cavity 11 of the storage container 1 can be scooped, effectively solving the problem of uneven addition caused by material accumulation.

[0058] In a feasible embodiment of the present utility model, as Figure 4As shown, the material picking structure 22 is a material picking spoon 221, and multiple material picking spoons 221 are spirally arranged along the length direction of the rotating shaft 21, and the rotation radius of multiple material picking spoons 221 decreases successively from one end of the rotating shaft 21 to the other end of the rotating shaft 21.

[0059] The multiple material picking spoons 221 distributed along the rotating shaft 21 in a spiral shape have different rotation radii, that is, the lengths of the material picking spoons 221 are different, so that the materials 10 at different depths in the accommodating cavity 11 of the storage container 1 can be scooped, effectively solving the problem of uneven addition caused by the accumulation of materials 10; further, only one material picking spoon 221 of these material picking spoons 221 is in the material picking position in every 360-degree spiral cycle, which effectively reduces the power of the driving motor 5 that drives the rotating shaft 21 to rotate, reduces energy consumption, and at the same time, the driving motor 5 can select a smaller volume, effectively saving installation space.

[0060] In this embodiment, the nozzle group 12 is a group, and in order to cooperate with each material spoon 221 to smoothly lower the material into each nozzle 121, each nozzle 121 in the nozzle group 12 is arranged inwardly along the width direction E of the storage container 1 from the first side wall 13 to the second side wall 14; of course, in other embodiments, each nozzle 121 in the nozzle group 12 can also be arranged at intervals along a direction parallel to the length direction F of the storage container 1, and it is only necessary to extend the material inlet 1211 of each nozzle 121 to the rotation path of the corresponding material spoon 221.

[0061] In this embodiment, the material dropped from the multiple nozzles 121 in the nozzle group 12 can be collected to achieve the problem of uniform addition of the material.

[0062] In another feasible embodiment of the present invention, as Figure 5 and Figure 6 As shown, each of the material taking structures 22 has at least a first material taking spoon 222 and a second material taking spoon 223 which are arranged at intervals along the circumferential direction of the rotating shaft 21 , and the rotation radius of the first material taking spoon 222 is greater than the rotation radius of the second material taking spoon 223 .

[0063] Each material picking structure 22 is designed to have a first material picking spoon 222 and a second material picking spoon 223 with different rotation radii, and the first material picking spoon 222 and the second material picking spoon 223 are spaced apart along the circumferential direction of the rotating shaft 21, that is, the first material picking spoon 222 and the second material picking spoon 223 have different lengths, thereby achieving the purpose of scooping materials 10 at different depths in the accommodating cavity 11 of the storage container 1, and effectively solving the problem of uneven addition caused by the accumulation of materials 10.

[0064] In this embodiment, the material nozzle 121 corresponding to each material picking structure 22 includes a first collecting trough 122 and a second collecting trough 123 arranged on the rotation path of the first material picking scoop 222 and the second material picking scoop 223, and the first collecting trough 122 and the second collecting trough 123 are connected to the feed port 1211.

[0065] Specifically, the nozzle group 12 can be a group, and the feed inlet 1211 of each nozzle 121 in the nozzle group 12 is connected to two collecting grooves, that is, the first collecting groove 122 and the second collecting groove 123. After the first material scoop 222 and the second material scoop 223 rotate along the rotating shaft 21 to dig out the material, they can be put into the first collecting groove 122 and the second collecting groove 123 respectively, and then the material 10 falls into the corresponding nozzle 121 through the first collecting groove 122 and the second collecting groove 123, so as to achieve the purpose of uniformly adding materials; of course, in other embodiments, In the embodiment, each of the material picking structures 22 may also include three material picking spoons spaced apart along the circumferential direction of the rotating shaft 21, namely, a first material picking spoon 222, a second material picking spoon 223 and a third material picking spoon 224. Correspondingly, three collecting troughs are connected above the material nozzle 121, namely, a first collecting trough 122, a second collecting trough 123 and a third collecting trough 124. The utility model does not limit the number of material picking spoons and the number of collecting troughs of the material picking structure 22, as long as the number of material picking spoons and the number of collecting troughs of each material picking structure 22 are the same.

[0066] Further, in a preferred embodiment, Figure 7 As shown, the first collecting trough 122 and the second collecting trough 123 are respectively arranged adjacent to the first material taking scoop 222 and the second material taking scoop 223. Specifically, the first collecting trough 122 and the second collecting trough 123 rotate synchronously with the rotation of the first material taking scoop 222 and the second material taking scoop 223. The first collecting trough 122 and the second collecting trough 123 can be connected with the inlet 1211 of the nozzle 121 through an external pipe, so as to achieve the purpose of dropping the material inside into the nozzle 121.

[0067] By placing the collecting trough close to the material taking spoon, the problem of material scattering that may occur during the rotation of the material taking spoon can be effectively solved, thereby ensuring the accuracy of the material addition amount.

[0068] In another feasible embodiment of the present utility model, as Figure 5 and Figure 7 As shown, the bottom of the accommodating cavity 11 is a semi-arc structure.

[0069] By adopting the holding chamber 11 with a semi-arc bottom structure, when the material taking spoon rotates to take materials, after scooping the material in the upper middle part of the holding chamber 11, the material in other parts of the holding chamber 11 will automatically move or flow to the middle part of the holding chamber 11, thereby increasing the fluidity of the material in the holding chamber 11 and avoiding the problem of uneven material addition caused by the accumulation of material 10.

[0070] According to one embodiment of the present utility model, Figure 8 and Fig. 9 As shown, the feeding device further comprises a hopper 3 located above the material storage container 1 , a material adding port 31 is provided at the lower end of the hopper 3 , and a switch valve 32 capable of adjusting the opening size thereof is provided at the material adding port 31 .

[0071] Specifically, the extension length of the hopper 3 is adapted to the length direction F of the storage container 1. By adding materials into the hopper 3, the materials can be transported to the storage container 1 through the material adding port 31 of the hopper 3 to replenish the materials. Furthermore, in this embodiment, the material adding port 31 can be staggered with the feed ports 1211 of each nozzle 121 of the nozzle group 12 in the storage container 1 to prevent the materials from directly falling into the feed ports 1211 of the multiple nozzles 121 through the material adding port 31.

[0072] In this embodiment, the switch valve 32 is a switch baffle, which is arranged adjacent to the material addition port 31, and the switch baffle can periodically open and close the material addition port 31. The switch baffle can be connected to a driving unit (not shown in the figure), which is connected to the driving unit through a controller, and the driving unit can be controlled to periodically open and close the material addition port 31. Among them, the frequency of the controller controlling the driving unit to drive the switch baffle to open and close the material addition port 31 can be selected and adjusted according to actual needs, and the utility model does not limit it. The controller controls the driving unit to periodically open and close the material addition port 31, which is conducive to the regular and quantitative replenishment of materials into the accommodating chamber 11.

[0073] In one embodiment of the present invention, a stirring structure (not shown in the figure) is provided in the hopper 3, and the stirring structure includes a stirring shaft rotatably connected to the hopper 3, and stirring blades connected to the stirring shaft.

[0074] By designing the stirring structure, the material poured into the hopper 3 can be disturbed to prevent the material from being blocked during the process of falling from the material adding port 31 into the material storage container 1, thereby affecting the efficiency of material adding.
