[0021] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0022] Example:
[0023] Please refer to Figures 1-7 As shown.
[0024] This application provides a stackable canned food feeding device, including a storage cabinet, wherein cat food cans 318 are stored inside the storage cabinet; The storage cabinet is equipped with a turntable transport system 2, which includes several spirally distributed transport and storage layers. The bottom of the turntable transport system 2 is equipped with a heat preservation and heating outlet system 4. The turntable transport system 2 is equipped with a low-temperature transmission power system 3 at its center. The cat food cans 318 are stacked in the transport and preservation layer and spirally arranged along the extension direction of the transport and preservation layer. The low-temperature transmission power system 3 is used to drive the cat food cans 318 to slide along the transport and preservation layer toward the heat preservation and heating outlet system 4.
[0025] Currently, there are significant limitations in the field of pet feeding, as wet pet food is prone to spoilage at room temperature. Therefore, it generally needs to be stored in a low-temperature environment, such as a refrigerator. Existing technologies typically stack wet food cans to save internal storage space when using a refrigerator to preserve wet pet food. However, this does not enable automatic feeding. Even with a smart transport vehicle 7 to load and unload the cans and a smart feeding turret 8 to open them, the stacked wet food cans still pose a significant risk of tipping over, causing the cans to scatter and affecting normal storage and feeding.
[0026] If pet food cans are not stacked in a pile manner, a lot of storage space will be wasted. Furthermore, if pet food cans stored in a single layer occupy a large area inside the refrigerator, it will be inconvenient to take them out. Therefore, how to make reasonable use of the low-temperature storage space inside the refrigerator to increase the storage capacity of cat food cans 318 and facilitate the taking out of cat food cans 318 has become an urgent problem to be solved in the field of pet wet food feeding equipment technology.
[0027] In this embodiment, by setting several spirally distributed transport and storage layers inside the storage cabinet, the cat food cans 318 can be stacked in a spiral arrangement within the transport and storage layers, thereby increasing the storage capacity of the cat food cans 318 inside the storage cabinet. Furthermore, the spiral stacking arrangement allows for the removal of all cat food cans 318 while maintaining only one outlet. Therefore, this embodiment includes a heat-insulating and heating outlet system 4 for removing all cat food cans 318. This system ensures smooth removal of the cat food cans 318 while effectively preventing the loss of cold air inside the storage cabinet, thus maintaining a low-temperature storage environment. Additionally, it heats the cat food cans 318 during removal, thereby protecting the pet's health.
[0028] In this embodiment, the turntable transport system 2 is used to drive the spirally stacked cat food cans with external force, thereby ensuring that the cat food cans 318 can be taken out one by one from the heat preservation and heating outlet system 4 in a spiral distribution.
[0029] The transport and preservation layer includes a track box 320, with an inlet spiral plate at the top and an outlet spiral plate at the bottom. A rotating track is provided inside the track box 320, and both the inlet spiral plate and the outlet spiral plate extend to the upper surface of the rotating track. The inlet spiral plate is connected to the outlet spiral plate of the upper transport and preservation layer, and the outlet spiral plate is connected to the inlet spiral plate of the lower transport and preservation layer. The cryogenic power transmission system 3 drives the rotating track to rotate horizontally.
[0030] In this embodiment, the track box 320 is used to accommodate the cat food can 318. The inlet spiral plate is connected to the upper transport and storage layer in a spiral distribution, and the outlet spiral plate is connected to the lower transport and storage layer in a spiral distribution. The rotating track can effectively move the cat food can 318 from the position of the inlet spiral plate to the position of the outlet spiral plate through its rotation, thereby realizing the transfer and transportation of the cat food can 318 from the upper transport and storage layer to the lower transport and storage layer.
[0031] The cryogenic transmission power system 3 is used to drive the rotating track to rotate, thereby driving the cat food can 318 mounted on the rotating track to move. Some external teeth can also be provided on the track housing 320, and a toothed ring that meshes with the external teeth is provided on the cat food can 318. The movement direction of the cat food can 318 is guided by the arrangement of the external teeth, which can effectively avoid the problem of the cat food can 318 being arranged chaotically when moving on the rotating track.
[0032] The rotating track includes a disc transport gear 33, and a disc transport bracket 34 is provided at the bottom of the disc transport gear 33. The disc transport bracket 34 is rotatably connected to the top of the next layer of transport and preservation layer. The cryogenic power transmission system can drive the disc transport gear 33 to rotate; The disc transport gear 33 is fixed with a mounting track, and the cat food can 318 is placed in the mounting track.
[0033] In this embodiment, the cryogenic power system 3 can drive the disc transport gear 33 to rotate, and the disc transport gear 33 is rotatably connected to the next transport and preservation layer through the disc transport bracket 34, thereby ensuring that the disc transport gear 33 can rotate relatively independently, while the disc transport bracket 34 can provide sufficient rotation space for the disc transport gear 33 to avoid negative impacts between adjacent transport and preservation layers.
[0034] The mounting track on the disc transport gear 33 can effectively accommodate the cat food can 318. The rotation of the disc transport gear 33 drives the rotation of the mounting track. When the mounting track rotates, the cat food can 318 can move from the position of the inlet spiral plate to the position of the outlet spiral plate by circumferential rotation. This allows the cat food can 318 to be transferred from the upper transport and preservation layer to the lower transport and preservation layer. In the further transfer process, it can be effectively transported into the heat preservation and heating outlet system 4, so that the cat food can 318 can be taken out to complete the feeding.
[0035] A silent ball bearing 319 is provided between the disc transport support 34 and the top of the next transport and storage layer; In the two adjacent transport and storage layers, the disc transport support 34 of the upper layer is rotatably connected to the top of the transport and storage layer of the lower layer via the silent ball bearing 319.
[0036] In this embodiment, in order to reduce the noise of mechanical operation from interfering with the pet and to avoid stress reactions in the pet, this embodiment effectively improves the smoothness of rotation and reduces the noise of mechanical operation by setting silent ball bearings 319 between the disc transport bracket 34 and the top of the next layer of transport and storage layer. This protects the pet to a certain extent and prevents the pet from being stressed by noise.
[0037] The side of the storage cabinet is equipped with an automatic electric door system 6, and the automatic electric door system 6 is equipped with an automatic lid opening system 5 that can open the cat food can 318. The automatic lid opening system 5 is connected to the heat preservation and heating outlet system 4.
[0038] In this embodiment, the automatic electric door system 6 completes the opening and closing of the storage cabinet, effectively reducing the loss of cold air inside the storage cabinet. The automatic lid opening system 5 can facilitate feeding by opening the cat food can, and can avoid the problem of the cat food can 318 expanding and deforming due to the heating operation at the heat preservation and heating outlet system 4.
[0039] In this embodiment, both the automatic power switch system 6 and the automatic cover opening system 5 are models that can be configured on a large scale in the prior art, which facilitates the mass production of this embodiment.
[0040] The low-temperature transmission power system 3 includes a rotating drive base. The refrigerator insulation layer 317 is provided inside the storage cabinet. The rotating drive base is located outside the refrigerator insulation layer 317. The rotating drive base extends into the refrigerator insulation layer 317 and is connected to a limiting power shaft 311. A main long shaft gear 35 is connected to the limiting power shaft 311. One end of the main long shaft gear 35 is connected to the limiting power shaft 311, and the other end is connected to several secondary long shaft gears 32. The main long shaft gear 35 corresponds to the bottom transport and storage layer, and each secondary long shaft gear 32 corresponds to one transport and storage layer: both the main long shaft gear 35 and the secondary long shaft gear 32 can drive the cat food can 318 in the transport and storage layer to slide.
[0041] In this embodiment, the rotating drive base is located outside the refrigerator insulation layer 317. Therefore, during the rotation process, the rotating drive base can effectively prevent the heat generated by mechanical energy from entering the refrigerator insulation layer 317. The rotating drive base, through the connection of the limiting power shaft 311, can effectively transmit the rotational power to the main long shaft gear 35 and the secondary long shaft gear 32, so that the main long shaft gear 35 and the secondary long shaft gear 32 can effectively rotate and drive the cat food can 318 in the transport preservation layer for transportation.
[0042] Each of the secondary long shaft gears 32 corresponds to a transport and storage layer, so that each transport and storage layer can be driven by the corresponding secondary long shaft gear 32 or the main long shaft gear 35, avoiding interruption in the intermediate transport process and avoiding mutual interference between the transport and storage layers.
[0043] In this embodiment, the limiting power shaft 311 can transmit the rotational driving force of the rotational drive base through rotation, and can ensure the stability of rotational transmission by limiting its own position, so as to achieve the purpose of stably and effectively transmitting the rotational driving force outside the refrigerator insulation layer 317 to the refrigerator insulation layer.
[0044] The secondary long shaft gear 32 is fitted with a combined bearing 31, and the secondary long shaft gear 32 is connected to the transport and preservation layer through the combined bearing 31. The main long shaft gear 35 and the secondary long shaft gear 32 are connected by a small deep groove ball bearing 316. The adjacent secondary long shaft gears 32 are also connected by small deep groove ball bearings 316.
[0045] In this embodiment, the combined bearing 31 is used to support the rotation of the secondary long shaft gear 32. A small deep groove ball bearing 316 is provided between the main long shaft gear 35 and the secondary long shaft gear 32. Since there are interlayer gaps between the secondary long shaft gear 32 and the main long shaft gear 35, and between adjacent secondary long shaft gears 32, in order to avoid the rotation of the main long shaft gear 35 and the secondary long shaft gear 32 affecting the transport and storage layer, the main long shaft gear 35 and the secondary long shaft gear 32 are connected sequentially by the small deep groove ball bearing 316. This can ensure the transmission of rotational driving force between the main long shaft gear 35 and the secondary long shaft gear 32, and also avoid the rotational influence of the main long shaft gear 35 and the secondary long shaft gear 32 on the outside world.
[0046] A lower limit heat insulation plate 38 is provided between the rotating drive base and the refrigerator insulation layer 317. The lower limit heat insulation plate 38 is attached to the refrigerator insulation layer 317. An upper limit heat insulation plate 37 is provided inside the refrigerator insulation layer 317. The upper limit heat insulation plate 37 and the lower limit heat insulation plate 38 are symmetrically distributed about the refrigerator insulation layer 317. The upper limit heat insulation plate 37 is attached to the refrigerator insulation layer 317.
[0047] In this embodiment, the lower limiting heat insulation plate 38 can limit the position of the limiting power shaft 311 and ensure that excessive heat loss occurs at the rotational connection position, thus limiting and preventing external heat sources from entering the refrigerator insulation layer 317. The upper limiting heat insulation plate 37 can limit the position of the limiting power shaft 311 and ensure that excessive heat loss occurs at the rotational connection position, thus limiting and preventing the loss of cold air from the refrigerator insulation layer 317. Under the combined action of the upper limiting heat insulation plate 37 and the lower limiting heat insulation plate 38, the position of the limiting power shaft 311 can be effectively restricted, and the low temperature environment inside the refrigerator insulation layer 317 can be effectively maintained.
[0048] The rotation drive base includes an AC synchronous motor 312, a motor gear 310 connected to the AC synchronous motor 312, and a drive gear 315 provided on the side of the motor gear 310. The motor gear 310 and the drive gear 315 mesh. A drive shaft 39 is fixed on the drive gear 315. The drive shaft 39 extends toward the refrigerator insulation layer 317 and is connected to the limiting drive shaft 311. The limiting drive shaft 311 is embedded in the refrigerator insulation layer 317. An embedded thrust bearing 321 is provided on the outer sleeve of the limiting drive shaft 311. The embedded thrust bearing 321 is fixed to the refrigerator insulation layer 317.
[0049] In this embodiment, the power source is provided by an AC synchronous motor 312. The motor gear 310 transmits driving force through meshing with the active force gear 315. The active force gear 315 transmits the driving force to the active force shaft 39, and the rotational driving force is transmitted to the limiting power shaft 311 through the rotation of the active force shaft 39, thereby realizing the driving of the limiting power shaft 311.
[0050] In this embodiment, by setting an embedded thrust bearing 321, the limiting power shaft 311 is prevented from affecting the refrigerator insulation layer 317 when it rotates.
[0051] The bottom of the main drive shaft 39 is provided with a base shell, and the bottom of the base shell is provided with a bottom thrust bearing 313, which is connected to the end of the main drive shaft 39. The base shell is also provided with a deep groove ball bearing 314, which is sleeved on the main drive shaft 39 and movably connected to the base shell.
[0052] In this embodiment, the base shell at the bottom of the active power shaft 39 can effectively bear the rotation of the active power shaft 39, and the bottom thrust bearing 313 can effectively support the rotation of the active power shaft 39. The active power shaft 39 and the base shell are movably connected through the deep groove ball bearing 314, thereby achieving the purpose of the active power shaft 39 rotating freely within the base shell.
[0053] In practical application, an automatic recycling system 1 is provided at the top of the storage cabinet in this embodiment. The automatic recycling system 1 in this embodiment can effectively recycle empty cat food cans 318, thereby avoiding the cat food cans 318 with residue in the room temperature environment from developing an odor.
[0054] In this embodiment, the storage cabinet contains cat food cans 318. When the pet owner sets a feeding time, the turntable transport system 2, powered by the low-temperature transmission power system 3, starts operating, transporting the pet food cans to the transport and storage layer at the bottom of the storage cabinet. The insulated heating outlet system 4 then activates, the automatic door system 6 opens, and the automatic lid opening system 5 opens the cat food cans 318. The cans slide into the insulated heating outlet system 4, where they are heated to bring them back to a temperature suitable for feeding. Once warmed, the insulated heating outlet system 4 moves the room-temperature cat food cans 318 to the intelligent transport vehicle 7, which then transports the opened cans to the intelligent feeding cradle 8. After the food is eaten... Then, the intelligent transport vehicle 7 transports the leftover cat food cans 318 to the automatic recycling system 1, which then transports them from the bottom to the top of the storage cabinet and puts them back inside. This completes the feeding process.
[0055] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
