Description

Technical Field

[0001] The present invention relates to the technical field of automatic cooking machines, and more particularly to a rotary material feeding mechanism and an automatic cooking machine. Background Art

[0002] There are a variety of cooking machines on the market currently, but the vast majority of them do not have the function of automatically feeding materials. On the one hand, Chinese dishes are very complex, with great differences in the forms of various materials, the sizes of ingredient portions, and the characteristics of the materials. On the other hand, the frying process of Chinese cuisine is very complex, and during the frying process of different dishes, there are strict requirements for the feeding sequence and feeding time of the materials. Therefore, material feeding has always been a difficult problem in the design of cooking machines, and the design of the material feeding module also needs to consider cleaning during use, especially when the material feeding module is used to feed meat, and the corresponding storage area must be cleaned thoroughly, otherwise a large number of bacteria will breed and generate odors.

[0003] To solve the above problems, the present invention provides a rotary material feeding mechanism and its cooking machine. The structure of this mechanism is simple, the function is reliable, it can accurately feed materials for the frying of most dishes, and the structure is simple and it is also very convenient to clean. Summary of the Invention

[0004] The object of the present invention is to provide a rotary material feeding mechanism that can be adapted to an intelligent cooking machine to accurately feed materials during the frying process.

[0005] The embodiments of the present invention can be implemented as follows:

[0006] The embodiments of the present invention provide a rotary material feeding mechanism, and the rotary material feeding mechanism includes:

[0007] A housing, a material dropping bottom hole is opened on the bottom plate of the housing, and the material to be fed passes through the material dropping bottom hole and freely falls into the frying pan of the intelligent cooking machine. A pipe shaft is also provided inside the housing;

[0008] The rotary material feeding mechanism further includes a rotary feeding barrel,

[0009] A circular tube is provided at the center of the rotary feeding barrel, the central circular tube is sleeved on the pipe shaft inside the housing, the rotary feeding barrel rotates around the pipe shaft inside the housing, and a driving motor assembly is provided outside the rotary feeding barrel. The driving motor assembly is fixed inside the housing and is used to drive the rotary feeding barrel to rotate.

[0010] A vertical upright plate is provided in the rotating feeding barrel, and the vertical upright plate is arranged along the radial direction of the rotating feeding barrel. The vertical upright plate is connected to the barrel wall and the central circular tube of the rotating feeding barrel, and the vertical upright plate divides the rotating feeding barrel into multiple spaces. The vertical upright plate, the barrel wall and the bottom plate of the outer shell form a storage space with a closed bottom surface. The multiple storage spaces are used to store materials. The rotating feeding barrel will drive the vertical upright plate to rotate together, and the bottom plate of the outer shell is stationary, so the multiple storage spaces will also rotate together. The materials in the multiple storage spaces will also rotate with the rotating feeding barrel and pass in sequence above the bottom hole of the material drop on the bottom plate of the outer shell.

[0011] The rotary feeding barrel also includes upper and lower sealing plates, which together with some of the vertical plates form a closed body, a material storage tube is provided in the closed body, corresponding notches are provided in the upper and lower sealing plates, the material storage tube passes through the upper and lower notches and is tightly and fixedly connected to the upper and lower sealing plates, part of the surface area of the closed body is penetrated by the material storage tube, and the material storage tube is also used to store materials.

[0012] The specific feeding principle is as follows:

[0013] The rotary feeding barrel rotates under the drive of the driving motor. As the rotary feeding barrel rotates, the closed body gradually staggers with the bottom hole on the outer shell, and the storage tube in the closed body is rotated to the top of the bottom hole in turn. At this time, the material in the storage tube will pass through the bottom hole in turn and fall into the wok of the cooking machine. As the rotary feeding barrel continues to rotate, the material in the storage space formed between the vertical plates will also be rotated to the top of the bottom hole in turn, and the material in the storage space will also pass through the bottom hole in turn and fall into the wok of the cooking machine, and the rotary feeding barrel continues to rotate. There are multiple position locators on the barrel wall, and corresponding sensors are provided in the outer shell. When each position locator rotates to the position of the sensor in turn, the sensor indirectly measures the relative position relationship between the corresponding storage interval and the bottom hole of the rotary feeding barrel. That is to say, whenever a storage space completely passes above the bottom hole of the feeding, the corresponding position locator just rotates to the position of the sensor. In this way, the system knows that the feeding of this feeding interval has been completed, and the system executes the feeding of the next feeding interval according to the control program. With the intermittent rotation of the rotary feeding barrel, the time-sharing feeding of the materials is completed.

[0014] Next, the rotating material feeding mechanism is further described in detail in conjunction with the engineering drawings. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0032] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0033] In the description of the present invention, it should be noted that if terms such as "upper", "lower", "inner", "outer", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the present invention is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present invention.

[0034] In addition, if terms such as "first", "second", etc. are used only for distinguishing descriptions, they cannot be understood as indicating or implying relative importance.

[0035] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0036] Figure 1 This is a perspective view of an automatic cooking machine 1.0 provided by an embodiment of the present invention. A rotary material feeding mechanism 2.0 is provided above the cooking machine 1.0, and a cooking pot 3.0 is provided below the rotary material feeding mechanism 2.0.

[0037] Figure 2 This is a perspective view of the rotary material feeding mechanism 2.0 provided by an embodiment of the present invention. The rotary material feeding mechanism includes a housing 10 and a rotary feeding barrel 20, as well as a sensor 30 installed on the housing.

[0038] Figure 3 This is an exploded view of the rotary material feeding mechanism provided by an embodiment of the present invention. In the figure, there is a drive motor assembly 40. The drive motor assembly 40 includes a drive wheel 401 and a component support 402. It should be noted that due to the perspective of the figure, the motor itself of the drive motor assembly 40 is not shown. The motor is installed below the drive wheel 401 and is blocked by the component support 402. The drive assembly 40 is fixed to the housing 10 through the component support 402, and the rotary feeding barrel 20 is driven to rotate by the drive wheel 401.

[0039] Combined with Figure 4 、 Figure 5 and Figure 6 , the structure of the rotary feeding barrel will be described:

[0040] The rotary feeding barrel 20 includes a barrel wall 201. A drive gear ring 202 is provided outside the barrel wall 201. The drive gear ring 202 meshes with the drive wheel 401, so that the rotary feeding barrel 20 is driven to rotate. It should be noted that only the direct drive method of gear meshing is provided in this embodiment to drive the feeding barrel to rotate. Of course, the rotary feeding barrel 20 can also be driven to rotate indirectly by using a transmission belt or the like. The drive method is not limited here and is within the protection scope of the present invention.

[0041] A vertical plate is provided inside the rotary feeding barrel 20. The vertical plate is arranged along the radial direction of the rotary feeding barrel. The vertical plate connects the barrel wall of the rotary feeding barrel and the central circular tube. And the vertical plate can be divided into two types: an independent vertical plate 205 and a closed vertical plate 209. The difference between these two types of plates is that the independent plate 205 divides the rotary feeding barrel 20 into different radial storage spaces, such as Figure 6 shown in the figure, dividing out a first separated storage space 212 and a second separated storage space 213. They can both store materials, generally the main materials for cooking.

[0042] The rotary feeding bucket 20 further includes an upper sealing plate 210 and a lower sealing plate 211. The upper sealing plate 210, the lower sealing plate 211, the closed vertical plate 209 and a part of the central cylinder construct a closed body. A material storage pipe is provided on the closed body. Notches are provided on the upper sealing plate 210 and the lower sealing plate 211. The material storage pipe penetrates through the notches and is tightly and fixedly connected to the upper and lower sealing plates. The material storage pipe is also used for storing materials, such as Figure 5 As shown, the material storage pipe includes a first material storage pipe 206, a second material storage pipe 207 and a third material storage pipe 208. The material storage pipe penetrates through the closed body. The surface of the part of the closed body that is not penetrated is represented by a sectional grid. See Figure 7 As shown

[0043] In Figure 7 As shown, the first material storage pipe 206 and the second material storage pipe 207 are closer to each other, and they are farther away from the third material storage pipe, with a relatively large closed area separated in the middle. The expansion angle 200 of the closed area represents the expansion range of this angle

[0044] In Figure 8 the expansion angle of the blanking bottom hole of the outer shell is 100. As can be seen from Figure 8 shown, the expansion angle 200 of the closed area is greater than the expansion angle 100 of the blanking bottom hole, so that when the two areas overlap, the closed area can completely cover the blanking bottom hole to prevent the fumes from entering the interior of the rotary feeding bucket 20 at this time

[0045] It should be emphasized that the number of vertical plates and material storage pipes in the rotary feeding bucket 20 is not limited, that is, the number of separated material storage spaces is also not limited, and their numbers are set completely according to actual needs

[0046] Furthermore, the reason for setting two ways of storing materials, namely the separated material storage space and the material storage pipe, is that the material storage pipe has a regular shape and a small cross-sectional area, which is suitable for storing seasonings such as green onions, ginger, garlic, and chili peppers, and is also suitable for storing meat materials such as meat slices and shredded meat. The outer shape of the material storage pipe is regular and easy to clean, and it can be quickly cleaned with a brush. The separated material storage space has a larger volume, is suitable for storing materials with a larger volume, and is not easily blocked when dropping

[0047] Combined with Figures 8 to 13 the feeding process of the rotary feeding bucket 20 is described as follows

[0048] Figure 8Schematic diagram of the feeding principle of the rotary material feeding mechanism provided by an embodiment of the present invention. As shown in the figure, the rotary feeding barrel 20 rotates counterclockwise under the drive of the drive motor assembly 40, and the closing body expansion angle 200 is greater than the blanking bottom hole expansion angle 100, so that the closing body can completely cover the blanking bottom hole 102 at an appropriate position.

[0049] Figure 9 Plan view of the starting position of the rotary material feeding mechanism provided by an embodiment of the present invention. As shown in the figure, at this time, the closing body completely covers the blanking bottom hole 102. Since the basic steps of stir-frying are to first heat the oil in the wok and start feeding the material after reaching the set oil temperature, this is the starting position for feeding the stir-frying machine. At this time, since the blanking bottom hole is blocked, no material can fall, and the oil fume cannot enter the rotary feeding barrel. At this time, a position locator 203 is at the sensor 30, and the stir-frying machine system records this as the starting position of stir-frying.

[0050] Then the rotary feeding barrel starts to rotate and reaches Figure 10 the position shown. At this time, the first material storage tube 206 rotates above the blanking bottom hole 102, and the material in the first material storage tube 206 falls into the wok 30, and the stir-frying machine starts to stir-fry the seasonings. At this time, another position locator 203 on the barrel wall 201 just rotates to the sensor 30, and at this time the system knows that the first material storage tube 206 has completed the feeding.

[0051] Similarly, referring to Figure 11 and Figure 12 shown, the rotary feeding barrel 20 continues to rotate counterclockwise according to the program control of the stir-frying machine, and sequentially completes the feeding of the materials in the second material storage barrel 207 and the first divided material storage space 212. The other position locators 203 on the barrel wall 201 pass by the sensor 30 one by one, and the stir-frying machine system detects that the above-mentioned material storage spaces have all completed the material feeding. Similarly, the second divided material storage space 213 also completes the material feeding under the program control of the stir-frying machine.

[0052] Figure 13 As shown, finally, a third material storage barrel 208 is provided for feeding materials. Considering that in actual stir-frying, many dishes need to be seasoned and then taken out of the pot finally, a third seasoning barrel 208 is set up to specifically store the final seasonings. If the dishes being stir-fried do not require it, the third material storage barrel 208 can be left without materials, and the system will control the rotary feeding barrel 20 to continue rotating without staying here. Therefore, starting from the actual needs, this material feeding mechanism is as comprehensive as possible in terms of hardware settings, laying a hardware foundation for supporting the software control of the stir-frying machine.

[0053] In summary, the above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims described above.
