[0043] Combine Figures 1 to 4 As shown, according to a specific embodiment of the present application, a feeding device is provided.

[0044] Specifically, the feeding device includes: a box body 10, a spiral conveying mechanism 20, and a powder accumulation prevention shell 70. The box body 10 has a accommodating chamber 11, a feed port 12, and a discharge port 13. The spiral conveying mechanism 20 is located within the accommodating chamber 11, and a material space is formed between the spiral conveying mechanism 20 and the side wall of the accommodating chamber 11. The discharge port 13 is connected to the material space. The spiral conveying mechanism 20 is capable of rotating about its own central axis to transport the material in the material space to the discharge port 13 along the axial direction of the spiral conveying mechanism 20. The powder accumulation prevention shell 70 is located within the accommodating chamber 11, between the box body 10 and the spiral conveying mechanism 20, and has a feed channel 71 therein. The first end of the feed channel 71 is connected to the feed port 12, and the second end of the feed channel 71 is connected to the material space.

[0045] In an embodiment of the present application, the feeding device includes a box body 10, a spiral conveying mechanism 20 and an anti-powder accumulation shell 70. The box body 10 has a accommodating chamber 11, a feed port 12 and a discharge port 13. The spiral conveying mechanism 20 is located in the accommodating chamber 11, and forms a material space between the spiral conveying mechanism 20 and the side wall of the accommodating chamber 11, and the discharge port 13 is connected to the material space. The spiral conveying mechanism 20 can rotate around its own central axis to transport the material axially to the discharge port 13. The anti-powder accumulation shell 70 is located between the box body 10 and the spiral conveying mechanism 20, and has a feed channel 71 inside. The first end of the feed channel 71 is connected to the feed port 12, and the second end is connected to the material space. When the material enters the box body 10 from the feed port 12, the spiral conveying mechanism 20 starts to rotate and transports the material axially to the discharge port 13. The anti-powder accumulation shell 70 can prevent the accumulation and accumulation of materials and ensure smooth flow of materials. The design of the feeding device effectively reduces the accumulation and blockage of materials, ensuring that the materials are smoothly conveyed to the discharge port 13. While improving production efficiency, it also ensures the stability and continuity of material conveying.

[0046] In an exemplary embodiment of the present application, the anti-powder accumulation shell 70 is arranged in the accommodating cavity 11 along the height direction of the box body 10. The anti-powder accumulation shell 70 has a through hole inside, which is extended along the height direction of the box body 10 to form a feeding channel 71.

[0047] Specifically, in this feeding device, a powder accumulation prevention housing 70 is located within the box body 10 and is arranged along the height direction of the box body. The housing 70 has through-holes extending along the height direction of the box body, forming a feeding channel 71. When material enters the box body 10 from the feed inlet 12, some of the material will pass through these through-holes into the housing 70, continue to flow downward along the direction of the through-holes, and eventually enter the material space of the screw conveyor mechanism 20. This design effectively guides and diverts material, prevents material accumulation and blockage, and improves the operating efficiency and stability of the entire feeding device.

[0048] Furthermore, the cross-sectional area of ​​the material delivery channel 71 is gradually increased from the first end of the material delivery channel 71 to the second end of the material delivery channel 71 .

[0049] Specifically, the cross-sectional area of ​​feed channel 71 gradually increases from its first end to its second end. When material enters the first end of feed channel 71 from feed inlet 12, the channel's cross-sectional area is relatively small, which helps control and guide the flow of the material. As the material moves along the feed channel toward the second end, the channel's cross-sectional area gradually increases, providing more space for the material to pass more smoothly and reducing the possibility of blockage and accumulation. This gradually increasing cross-sectional area effectively optimizes the material flow path and improves the conveying efficiency and stability of the entire feeding device.

[0050] Furthermore, an end of the powder accumulation prevention shell 70 close to the feed port 12 is provided with a flange structure 72 folded toward the side of the spiral conveying mechanism 20 .

[0051] Specifically, flange structure 72 is located at one end of powder accumulation prevention housing 70 near feed inlet 12, folded toward one side of screw conveyor mechanism 20. When material enters powder accumulation prevention housing 70 from feed inlet 12, flange structure 72 guides the material to the correct location, preventing it from accumulating or stagnating at feed inlet 12. The provision of flange structure 72 allows for better control of material flow, ensuring smooth entry into the screw conveyor mechanism for transport, thereby improving the operating efficiency and stability of the entire feeding device.

[0052] Furthermore, each side wall of the anti-powder accumulation housing 70 is set at an angle A with respect to the height direction of the anti-powder accumulation housing 70 , wherein 15°≥A≥5°.

[0053] Specifically, the angle A causes the sidewalls of the powder-prevention housing 70 to tilt inward, creating a gradually narrowing channel as the material flows. This design helps guide and control the flow of material, preventing accumulation within the powder-prevention housing 70. Furthermore, the tilted sidewalls reduce friction between the material and the housing, improving material flow efficiency.

[0054] Furthermore, at least one sidewall of the powder-prevention housing 70 is provided with a guide groove extending along the length of the sidewall. This guide groove allows material to flow along a specific path along the sidewall, preventing it from moving or accumulating within the powder-prevention housing 70. The extended length of the guide groove provides a longer guide path, ensuring smooth material flow without blockage or accumulation. Furthermore, the guide groove helps reduce friction between the material and the sidewall, improving material flow efficiency.

[0055] Furthermore, the feed port 12 is provided at the top of the box body 10 , and the discharge port 13 is provided at the bottom of the box body 10 .

[0056] In another exemplary embodiment of the present application, the spiral conveying mechanism 20 has a first end close to the discharge port 13, and the spiral conveying mechanism 20 has a second end away from the discharge port 13, and the outer diameter of at least part of the spiral conveying mechanism 20 is gradually reduced along the direction from the second end to the first end.

[0057] Specifically, the outer diameter of the screw conveyor mechanism 20 gradually decreases from its second end, distal to the discharge port 13, toward its first end, proximal to the discharge port 13. This design allows the screw pitch of the screw conveyor mechanism 20 to gradually decrease, thereby gradually increasing the density and compression of the material during the conveying process. This gradually decreasing outer diameter design helps improve the fluidity of the material during conveying, reduces friction and resistance between the materials, and improves the efficiency of the entire conveying process.

[0058] Furthermore, the spiral conveying mechanism 20 includes a first conveying section 21 and a second conveying section 22. The first conveying section 21 is located on the side of the accommodating chamber 11 away from the discharge port 13. The first conveying section 21 is rotatably connected to the box body 10. One end of the second conveying section 22 is connected to the first conveying section 21, and the other end of the second conveying section 22 extends into the discharge port 13. The outer diameter of the first conveying section 21 remains unchanged along the direction from the second end to the first end, and the outer diameter of the second conveying section 22 is gradually reduced along the direction from the second end to the first end.

[0059] Specifically, the first conveying section 21 is responsible for conveying the material from the side away from the discharge port 13 to the second conveying section 22, while the second conveying section 22 is responsible for smoothly conveying the material to the discharge port 13. Because the outer diameter of the second conveying section 22 gradually decreases along the conveying direction, the density and compressibility of the material are gradually increased, thereby improving the fluidity and efficiency of the material during the conveying process. This achieves more precise control of the material conveying process, avoiding problems such as blockage and accumulation. This ensures smooth material conveyance from the feed port 12 to the discharge port 13, improving the operating efficiency and stability of the entire device.

[0060] Furthermore, along the direction from the second end to the first end, the heights of the bottom planes of the box body 10 at positions corresponding to the first conveying section 21 are gradually increased.

[0061] Specifically, as the box body 10 moves from the second end to the first end, the height of the bottom plane at the position corresponding to the first conveying section 21 gradually increases. This gradually increasing height design allows the material to gradually tilt downward during the conveying process, facilitating the natural flow of the material to the first conveying section 21 and preventing the material from getting stuck or accumulating during the conveying process.

[0062] Furthermore, the discharge port 13 is protrudingly provided on a side wall of the box body 10 , and a discharge channel is formed inside the discharge port 13 , and one end of the spiral conveying mechanism 20 close to the discharge port 13 extends into the discharge channel.

[0063] Specifically, the discharge port 13 protrudes from the side wall of the box body 10, forming a channel that allows the material to flow out smoothly. The discharge channel formed within the discharge port 13 helps control the flow direction of the material, preventing blockage and accumulation. At the same time, the end of the spiral conveying mechanism 20 near the discharge port 13 extends into the discharge channel, ensuring that the material is smoothly conveyed to the discharge port 13, improving the efficiency and stability of material transportation.

[0064] Furthermore, the screw conveying mechanism 20 includes: a screw 23 rotatably connected to the box body 10 ; and blades 24 , which are spirally arranged on the outer peripheral surface of the screw 23 along the axial direction of the screw 23 .

[0065] Specifically, screw 23 is connected to housing 10 and, through rotation, conveys material from feed port 12 to discharge port 13. Blades 24 are helically arranged on the outer circumference of screw 23 along its axial direction, promoting and conveying the material. As screw 23 rotates, blades 24 form a helical structure on its outer surface, pushing and conveying the material along the axial direction of screw 23 to discharge port 13. The coordinated operation of screw 23 and blades 24 ensures smooth material transfer and maintains stability during the conveying process, improving production efficiency and operational stability.

[0066] Furthermore, the screw 23 is a hollow rod-shaped structure with a through hole on its inner side. A plurality of ribs are arranged on the inner side wall of the screw 23 at intervals along the circumferential direction, and the extending direction of the ribs is parallel to the axial direction of the screw 23 .

[0067] Specifically, the interior of screw 23 is hollow and has through-holes, allowing material to be conveyed through it. Multiple ribs are equally spaced along the inner sidewall of screw 23, oriented parallel to the axis of screw 23. This design increases the rigidity and strength of screw 23, improving its stability and durability during conveying. Furthermore, the parallel arrangement of the ribs ensures smoother and more stable material conveyance within screw 23, preventing blockage or obstruction during conveying.

[0068] Furthermore, the feeding device also includes an end cover 30. A mounting hole is provided on the other side wall of the box body 10 opposite to the side wall where the discharge port 13 is located. Part of the end cover 30 is located in the mounting hole, and the end cover 30 is detachably connected to the box body 10.

[0069] Specifically, the end cap 30 is located on the other side wall of the box body 10, opposite the side wall where the discharge port 13 is located. This side wall is provided with a mounting hole, into which a portion of the end cap 30 can be installed, thereby connecting to the box body 10. The end cap 30 and the box body 10 are connected in a detachable manner. The installation of the end cap 30 effectively seals the feeding device structure, preventing material from spilling or falling from the side and ensuring smooth flow of material to the discharge port.

[0070] Furthermore, a sealing groove is provided on the outer peripheral surface of the portion of the end cover 30 located in the mounting hole, and a sealed space is formed between the hole wall of the mounting hole and the sealing groove, and a sealing member 80 is provided in the sealed space.

[0071] Specifically, a sealing groove is provided on the outer circumference of the partial end cap 30, forming a sealed space between the sealing groove and the wall of the mounting hole. A sealing member 80 is positioned within this sealed space to fill the space and ensure a good seal. When the partial end cap 30 is installed in the mounting hole, the sealing space between the sealing groove and the wall of the mounting hole is filled by the sealing member 80, effectively preventing material or other impurities from penetrating or leaking through the hole wall.

[0072] Furthermore, the screw 23 is passed through the mounting hole and is located inside the end cover 30 . The feeding device further includes a limiting ring 40 . Along the radial direction of the screw 23 , the limiting ring 40 is located between the screw 23 and the end cover 30 .

[0073] Specifically, a portion of the screw 23 is located on the inner side of the end cover 30. The limiting ring 40 is arranged along the radial direction of the screw 23 and is located between the outer side of the screw 23 and the end cover 30. The function of the limiting ring 40 is to limit the movement range of the screw 23 in the axial direction to prevent the screw 23 from deviating or detaching from the device during operation. By setting the limiting ring 40, it can be ensured that the screw 23 operates in the appropriate position, ensuring the normal operation of the feeding device. The design of the screw 23 passing through the end cover 30 forms a seal between the screw 23 and the end cover 30, preventing material leakage or external substances from entering.

[0074] Furthermore, a connecting portion is provided inside the end cover 30 , in which a magnetic body 50 is installed. The magnetic body 50 is in an adsorbed state with another magnetic structure on the installation base, so that the feeding device is connected to the installation base.

[0075] Specifically, a magnetic body 50 in an adsorbed state is installed in the connection part. When the feeding device needs to be installed or fixed in a specific position, the magnetic body 50 can be adsorbed on the magnetic structure of the installation base, achieving a quick and convenient connection. This magnetic adsorption connection method has strong stability and reliability, and is also easy to disassemble and move.

[0076] Furthermore, the feeding device further includes: a driving part, which is connected to the screw conveying mechanism 20, and the driving part has a starting state to drive the screw conveying mechanism 20 to rotate along its own axis.

[0077] Specifically, when the drive unit is activated, the power or energy it provides is transferred to the screw conveyor mechanism 20, causing the screw conveyor mechanism 20 to rotate along its own axis. This rotational motion enables the screw conveyor mechanism 20 to effectively convey material from the feed inlet 12 to the discharge outlet 13. Through the action of the drive unit, the screw conveyor mechanism 20 of the feeding device can smoothly carry out its conveying work, improving the material conveying efficiency.

[0078] Furthermore, the feeding device also includes a discharge nozzle assembly 60, which is detachably connected to the discharge port 13. The discharge nozzle assembly 60 is used to feed the material discharged through the discharge port 13 to a target location.

[0079] Specifically, the discharge nozzle assembly 60 is used to process material discharged from the discharge port 13. It is detachably connected to the discharge port 13. The design and installation of the discharge nozzle assembly 60 ensure smooth material delivery from the discharge port 13, avoiding blockage or leakage. This detachable connection makes installation and maintenance of the discharge nozzle assembly 60 more convenient and quicker.

[0080] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, an automatic cooking robot is provided, and the automatic cooking robot includes a feeding device, and the feeding device is the feeding device mentioned above.
