[0002] The addition of seasonings is a key link in the cooking process. It is necessary to grasp the timing of addition and accurately control the amount to ensure that the cooked dishes taste delicious.

[0003] Most of the existing seasoning feeding devices use a plurality of relatively independent feeding tanks. When feeding is required, each feeding tank performs the feeding operation separately.

[0004] The above-mentioned seasoning delivery device has the following defects: each feeding tank needs to be provided with a driving device for driving the seasoning to be discharged, which increases the cost, occupies a large volume, and is difficult to set up the wiring. The above-mentioned defects also make it difficult to miniaturize the feeding device, and it is inconvenient to use it in the home. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the seasoning feeding device in the prior art that the device is large in size and high in cost, and to provide a solid seasoning feeding device and an automatic cooking machine.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] A solid seasoning feeding device comprises a plurality of feeding devices and a driving mechanism, and is characterized in that: the feeding device can switch between a working state connected to the driving mechanism and a static state in which the transmission is released from the driving mechanism; the solid seasoning feeding device also comprises a selection mechanism, the selection mechanism is connected to the driving mechanism through a one-way transmission mechanism, and can move with the driving mechanism when it moves in a forward direction and release the transmission when it moves in a reverse direction; the selection mechanism passes through selection positions corresponding to a plurality of the feeding devices along the path of the driving mechanism when it moves in the forward direction, and the selection mechanism can switch the feeding device from a static state to a working state when reaching the selection position.

[0008] The specific working mode of the unloading device is as follows:

[0009] S10: The driving mechanism rotates forward, driving the selection mechanism to reach the selection position, and driving the corresponding unloading device to reach the working state;

[0010] S20: The driving mechanism rotates in the reverse direction, the position of the selection mechanism remains unchanged, and the unloading device operates until unloading is completed;

[0011] S30: Repeat steps S10 and S20 until the material unloading is completed.

[0012] The solid seasoning feeding device of the present invention can realize seasoning selection operation and seasoning feeding operation through only one driving mechanism, effectively saving costs and reducing volume. A cooking machine using such a solid seasoning feeding device can be more miniaturized and convenient to use in a home environment.

[0013] Preferably, the working state corresponds to the state of the material discharging device in the working position, the static state corresponds to the state of the material discharging device in the static position, the moving path of the selection mechanism partially overlaps with the multiple material discharging devices in the static position, and the selection mechanism can drive the material discharging device to move from the static position to the working position when reaching the selection position, thereby realizing the selective discharging of the material discharging device.

[0014] Preferably, the solid seasoning feeding device further comprises a reset member, which can apply a biasing force to the feeding device to drive it to move toward a static state. The reset member can drive the feeding device to reset from the working position to the static position after the selection mechanism leaves the selection position, thereby stopping the feeding action of the feeding device and meeting the subsequent cycle operation requirements.

[0015] Preferably, the unloading device is connected to the driving mechanism via a clutch device, the static state corresponds to a state when the clutch device is released, the working state corresponds to a state when the clutch device is connected, and a power-on structure is provided at the selection position. When the selection mechanism reaches the selection position, it can contact the power-on structure to energize the clutch device and switch it to a connected state.

[0016] The static state corresponds to the state when the clutch device is released from connection, and the working state corresponds to the state when the clutch device is connected. An energizing structure is provided at the selection position. When the selection mechanism reaches the selection position, it can contact the energizing structure to energize the clutch device and switch it to the connection state. At this time, the main body is connected to the driven shaft, and the unloading operation can be performed.

[0017] Preferably, the driving mechanism includes a main gear, and a plurality of the feeding devices are arranged on the circumferential side of the main gear and have a driven gear that can mesh with the main gear, and the driven gear is axially offset from the main gear when the feeding device is in a stationary state, and is drivingly meshed with the main gear when the feeding device is in a working state. The use of the above planetary gear-like structure allows the main gear to drive multiple driven gears at the same time and effectively saves horizontal area occupation. The driven gear is arranged to be axially offset from the main gear, and the axial movement of the feeding device can be driven by the selection mechanism to achieve engagement or disengagement with the driving gear. Such an arrangement does not require the feeding device to reserve space for its movement on the horizontal plane, thereby reducing the horizontal area occupation, which is conducive to further reducing the volume of the cooking machine using the solid feeding device.

[0018] Preferably, the driving mechanism further comprises a driving shaft passing through the main gear, the selection mechanism is connected to the driving shaft via a one-way transmission mechanism, and the selection mechanism is provided with an interference portion extending axially toward the direction of the unloading device, the movement path of the interference portion overlaps with a plurality of the unloading devices in a stationary state, and the axial height of the overlapping portion of the interference portion and the unloading device is greater than the axial spacing between the driven gear in a stationary state and the main gear. Therefore, when the interference portion runs through the unloading device, it can push the unloading device to move downward until the driven gear meshes with the main gear, thereby realizing the operation of the unloading device.

[0019] Preferably, the unloading device includes a driven shaft and a main body part, the driven shaft is inserted into the driven gear, the driven gear and the driven shaft can move axially relative to the main body part, one end of the driven shaft can be connected to the main body part to prevent rotation, and the other end is arranged in cooperation with the interference part.

[0020] Such a structure makes it unnecessary for the unloading device to be raised or lowered as a whole, which reduces the number of moving parts and reduces the difficulty of manufacturing on the one hand. On the other hand, since the main part is a relatively static structure, it is convenient to seal the seasoning compartment for storing seasonings to prevent the seasonings from getting damp. In addition, such a setting also reduces the contact area of ​​the unloading device when it slides, which helps to reduce sliding friction and prevent the falling device from getting stuck due to increased friction caused by wear after long-term use.

[0021] Preferably, the driving mechanism includes a closed-loop transmission chain, and a plurality of the unloading devices are arranged along the transmission chain. The unloading device includes a transmission wheel that can cooperate with the transmission chain for transmission, and the transmission wheel is axially offset from the transmission chain when the unloading device is in a stationary state; and is engaged with the transmission chain when the unloading device is in a working state.

[0022] S10: The transmission chain rotates forward to drive the selection module to move along the trajectory to the selection position. At this time, the interference piece on the selection mechanism contacts the unloading device, driving the unloading device to switch from the static state to the working state;

[0023] S20: The transmission chain rotates in the reverse direction, the selection module does not move, and the unloading device operates to perform the unloading operation;

[0024] Repeat the above steps S10 and S20 until all the unloading devices have finished unloading.

[0025] The selection mechanism and driving mechanism of the above solution can also perform selection operations and material removal operations.

[0026] Preferably, the selection mechanism includes a guide rail placed above the transmission chain and with a trajectory overlapping with the transmission chain, a selection module placed on the guide rail, the selection module being connected to the transmission chain via a one-way transmission mechanism, and the selection mechanism being provided with an interference member extending axially toward the direction of the unloading device, the movement path of the interference member overlapping with a plurality of the unloading devices in a stationary state, and the axial height of the overlapping position of the interference member and the unloading device being greater than the axial spacing between the transmission wheel in a stationary state and the transmission chain.

[0027] Preferably, the one-way transmission device comprises a ratchet and a pawl, and the ratchet and the pawl are respectively arranged on the selection mechanism and the driving mechanism, thereby realizing one-way transmission.

[0028] Preferably, the feeding device comprises a grinding quantity control component, and the grinding quantity control component comprises:

[0029] An outer sleeve, wherein the inner circumference of the outer sleeve is formed with a coarse ground thread and a fine ground thread in sequence along the axial direction, and the pitch of the coarse ground thread is greater than the pitch of the fine ground thread;

[0030] A grinding cone, which is arranged inside the outer sleeve; the cone surface of the grinding cone is provided with coarse grinding ribs and fine grinding ribs;

[0031] The conical surface of the grinding cone and the inner circumference of the outer sleeve form a grinding space, and the two ends of the outer sleeve respectively form a feed port and a discharge port. The coarse grinding ribs are close to the feed port, and the fine grinding ribs are close to the discharge port. The distance between the grinding cone and the outer sleeve gradually decreases from the feed port to the discharge port.

[0032] When in use, large-particle seasoning is put into the grinding space from the feed port, and the outer sleeve or grinding cone is rotated. Under the action of the coarse grinding thread and the coarse grinding rib, the large-particle seasoning is squeezed and crushed into small-particle seasoning. As the distance between the grinding cone and the outer sleeve gradually decreases from the feed port to the discharge port, the seasoning particles become smaller and continue to roll and approach the discharge port. When the size of the seasoning particles is small enough to roll into the grinding space composed of the fine grinding thread and the fine grinding rib, the seasoning particles are further squeezed and crushed. When the distance between the fine grinding thread and the fine grinding rib is getting closer and closer, the seasoning particles are further broken and become smaller. When the seasoning particles are small enough, they are discharged from the discharge port, completing the entire feeding process. And when the grinding control component is in operation, each grinding space has seasoning particles of different sizes. Whenever the grinding cone and the outer sleeve rotate relative to each other, the corresponding amount of seasoning will fall from the discharge port.

[0033] Preferably, the coarse grinding ribs and the fine grinding ribs are both arranged obliquely on the conical surface of the grinding cone. The oblique arrangement of the coarse grinding ribs and the fine grinding ribs is conducive to cooperating with the fine grinding thread and the coarse grinding thread to grind the seasoning finely and evenly.

[0034] Preferably, the extension direction of the coarse grinding thread is staggered with the extension direction of the coarse grinding rib; the extension direction of the fine grinding thread is staggered with the extension direction of the fine grinding rib. The extension direction of the fine grinding thread is staggered with the extension direction of the fine grinding rib. In this embodiment, the above-mentioned staggered setting can grind the seasoning finely and evenly, and can also have the effect of squeezing and crushing the seasoning.

[0035] Preferably, the feeding device further comprises a volume control component, comprising:

[0036] A second driven shaft; an upper blanking plate, a quantitative bin and a lower blanking plate which are sequentially arranged and fit together along the axial direction of the second driven shaft, the quantitative bin is axially connected to the second driven shaft, the upper blanking plate is provided with an upper blanking port, the lower blanking plate is provided with a lower blanking port, and the lower blanking port and the upper blanking port do not overlap axially; the quantitative bin is provided with a quantitative hole which penetrates axially;

[0037] The second driven shaft can drive the quantitative bin to rotate;

[0038] Or, the upper blanking plate or the lower blanking plate rotates relative to the quantitative bin;

[0039] The relative motion tracks of the quantitative hole and the upper blanking plate and the lower blanking plate coincide with the upper blanking hole and the lower blanking hole in turn.

[0040] Specifically, the upper drop plate and the lower drop plate are attached to the upper and lower end surfaces of the quantitative bin, and the lower drop port, the upper drop port and the quantitative hole do not overlap axially. When there is a need for unloading, the upper drop plate is rotated to overlap the upper drop port with the quantitative hole of the quantitative bin, so that the seasoning can fall into the quantitative hole. The definition of overlapping the upper drop port with the quantitative hole of the quantitative bin here includes but is not limited to complete overlap and partial overlap, both of which can allow the seasoning to fall into the quantitative hole. At this time, the quantitative bin or the lower drop plate is rotated, and the seasoning in the quantitative hole will separate from the quantitative hole under the action of gravity and fall from the lower drop port to complete the quantitative unloading.

[0041] Preferably, the volume control assembly further comprises a control assembly lock, which is connected to one end of the second driven shaft close to the lower blanking plate, and is used to axially limit the lower blanking plate, the quantitative bin and the upper blanking plate. By arranging the control assembly lock at the lower end of the second driven shaft, the lower blanking plate, the quantitative bin and the upper blanking plate are prevented from falling off.

[0042] Preferably, the control assembly lock head and the second driven shaft are threadedly connected. The threaded connection fixes the control assembly lock head and the second driven shaft together, which has a simple structure and is easy to disassemble. The purpose of fixing and disassembling can be achieved by only tightening or unscrewing the control assembly lock head. In other possible implementations, other connection methods may also be used, such as other structures such as buckles.

[0043] Preferably, the volume control component further includes a boss group, the second driven shaft passes through the boss group, and the boss group is arranged between the volume control component lock head and the lower blanking plate. Specifically, the boss group is arranged to abut the volume control component lock head and the lower blanking plate to prevent the volume control component lock head from becoming tighter or looser due to continuous friction between the lower blanking plate and the volume control component lock head when the volume control component lock head and the second driven shaft are threadedly connected.

[0044] Preferably, the boss group includes a first boss and a second boss that fit each other, the first boss is coaxially slidably connected to the lower blanking plate, and the second boss is connected to the control assembly lock. As above, the friction force on the control assembly lock is further reduced.

[0045] Preferably, the unloading device includes a driven shaft and a main body, the main body includes a seasoning bin, the driven shaft is provided with an elastic part facing one side of the seasoning bin, the seasoning bin is provided with a protruding interference rib, and the elastic part can deform and pass over the interference rib after abutting against the interference rib. Specifically, when the driven shaft rotates, it drives the elastic part to rotate, and the elastic part hits the interference rib on the seasoning bin during the rotation process, and the vibration generated is transmitted to the inside of the seasoning bin, so that the seasoning inside the seasoning bin is vibrated and scattered, thereby avoiding the seasoning from being compacted, and the scattered seasoning is easier to unload, thereby improving the unloading efficiency.

[0046] Preferably, the seasoning bin includes a platform area and a groove area, and the driven shaft is arranged inside the groove area. The driven shaft is arranged in the groove area, that is, a recessed area is arranged on the seasoning bin, and the driven shaft is arranged in this recessed area. Therefore, the elastic part located on the driven shaft is also located in the groove area, and the interference ribs on the seasoning box are also arranged on the inner side wall of the groove area for the elastic part to collide. The above-mentioned structural form can make the overall structure more stable. Compared with setting the rotating part in other positions, such as the inside of the seasoning bin, the above-mentioned structural form also has a simple manufacturing process, reduced volume, and reduced risk of interference between debris and the rotating elastic part.

[0047] Preferably, the surface of the groove area facing the driven shaft is arranged to fit the area swept by the elastic part during rotation. With the above structure, the contact surface of the elastic part and the interference rib is larger, and a stronger impact vibration effect can be obtained.

[0048] The present invention also provides an automatic cooking machine, comprising the solid seasoning feeding device as described in any one of the above.

[0049] The positive and progressive effects of the present invention are:

[0050] The solid seasoning feeding device of the present invention can realize seasoning selection operation and seasoning feeding operation through only one driving mechanism, effectively saving costs and reducing volume. A cooking machine using such a solid seasoning feeding device can be more miniaturized and convenient to use in a home environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0112] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0113] Example 1

[0114] Combination Figure 1 , Figure 2 as well as Figure 3 A solid seasoning feeding device 100 includes multiple feeding devices 100, a driving mechanism 200 and a selection mechanism 300.

[0115] The feeding device 100 can be used to store seasonings and perform a feeding operation after receiving a feeding command. The feeding device 100 can switch between a working state in transmission connection with the driving mechanism 200 and a static state in contact transmission with the driving mechanism 200.

[0116] Combination Figure 4 The selection mechanism 300 is connected to the driving mechanism 200 through a one-way transmission mechanism 310, which can move with the driving mechanism 200 when it moves in the forward direction, and release the transmission when it moves in the reverse direction. Specifically in the present invention, the one-way transmission device includes a ratchet 311 and a pawl 312, which are respectively arranged on the selection mechanism 300 and the driving mechanism 200. The ratchet 311 is provided with a plurality of one-way teeth 313 along the circumferential direction. When the driving mechanism 200 rotates forward, the pawl 312 can be inserted between two adjacent one-way teeth 313 to achieve the locking of the selection mechanism 300 and the driving mechanism 200. When the driving mechanism 200 rotates reversely, the pawl 312 slides over the tooth back of the one-way tooth 313, and the rotation mechanism is released from the driving mechanism 200.

[0117] The selection mechanism 300 moves along the path of the driving mechanism 200 in the forward direction and passes through selection positions corresponding to a plurality of unloading devices 100 . When the selection mechanism 300 reaches the selection position, the unloading device 100 can be switched from a static state to a working state.

[0118] The specific working mode of the unloading device 100 is as follows:

[0119] S10: The driving mechanism 200 rotates forward, driving the selection mechanism 300 to reach the selection position, and driving the corresponding unloading device 100 to reach the working state;

[0120] S20: The driving mechanism 200 rotates in the reverse direction, at which time the position of the selection mechanism 300 remains unchanged, and the unloading device 100 operates until unloading is completed;

[0121] S30: Repeat steps S10 and S20 until all the unloading devices 100 have finished unloading.

[0122] The solid seasoning feeding device 100 of the present invention can realize seasoning selection operation and seasoning feeding operation of multiple feeding devices 100 only through one driving mechanism 200, which effectively saves cost and reduces volume. A cooking machine using such a solid seasoning feeding device 100 can be more miniaturized and convenient to use in a home environment.

[0123] In this embodiment, the selection mechanism 300 drives the unloading device 100 to switch from the static state to the working state in the following manner:

[0124] The working state of the material discharge device 100 corresponds to the state of the material discharge device 100 in the working position, and the static state corresponds to the state of the material discharge device 100 in the static position. The moving path of the selection mechanism 300 partially overlaps with the multiple material discharge devices 100 in the static position. When the selection mechanism 300 reaches the selection position, it can physically contact the material discharge device 100 and drive the material discharge device 100 to move from the static position to the working position. In this way, the selective discharge of the material discharge device 100 is realized.

[0125] In this embodiment, the solid seasoning feeding device 100 further includes a reset member 400, which can apply a biasing force to the feeding device 100 to drive it to move toward the static position. The reset member 400 can drive the feeding device 100 to reset from the working position to the static position after the selection mechanism 300 leaves the selection position, thereby stopping the feeding action of the feeding device 100 and meeting the subsequent cycle operation requirements.

[0126] In some alternatives, the selection mechanism 300 can also drive the unloading device 100 to switch from the static state to the working state in the following manner:

[0127] The unloading device 100 is connected to the driving mechanism 200 via a clutch device, and the clutch device is arranged as follows: the unloading device 100 includes a main body 120 for unloading and a driven shaft 130, the driven shaft 130 is connected to the driving mechanism 200 and keeps rotating, and the main body 120 and the driven shaft 130 are connected via a clutch device. The static state corresponds to the state when the clutch device is disconnected, and the working state corresponds to the state when the clutch device is connected. A power-on structure is provided at the selection position, and the selection mechanism 300 can contact the power-on structure when reaching the selection position to energize the clutch device and switch it to the connection state. At this time, the main body 120 is connected to the driven shaft 130, and the unloading operation can be performed.

[0128] The operation mode of the structure is as follows: when the unloading device 100 is in a stationary state, the clutch is in a disconnected state. When the selection mechanism 300 reaches the selection position, the clutch is energized and switched to a connected state. At this time, the operating part is transmission-connected with the driven shaft 130, and the operating part can perform unloading operations.

[0129] Compared with the previously mentioned mechanical transmission method, this method has a more convenient structural layout, but it increases additional costs. Therefore, the present invention still preferably adopts the solution of using the selection mechanism 300 to mechanically drive the unloading device 100 to switch.

[0130] Combination Figure 1 and Figure 2 In this embodiment, the driving mechanism 200 includes a main gear 210, a driving shaft 220 passing through the main gear 210, and a main motor 221 connected to the driving shaft 220. Thus, the main gear 210 can be driven to rotate by the main motor 221.

[0131] Multiple feeding devices 100 are respectively arranged on the circumferential side of the main gear 210 and have a driven gear 110 that can mesh with the main gear 210. The driven gear 110 is axially offset from the main gear 210 when the feeding device 100 is in a stationary state, and is in driving meshing with the main gear 210 when the feeding device 100 is in a working state. The use of the above planetary gear-like structure allows the main gear 210 to drive multiple driven gears 110 at the same time and effectively saves horizontal area occupation. The driven gear 110 is arranged to be axially offset from the main gear 210, and the axial movement of the feeding device 100 can be driven by the selection mechanism 300 to achieve engagement or disengagement with the driving gear. Such an arrangement does not require the feeding device 100 to reserve space for its movement on the horizontal plane, thereby reducing the horizontal area occupation, which is conducive to further reducing the volume of the cooking machine using the solid seasoning feeding device 100.

[0132] Combination Figure 1 and Figure 3In this embodiment, the selection mechanism 300 includes a rotating disk 320, which is connected to the driving mechanism 200 in a one-way transmission manner through a one-way transmission mechanism 310. The rotating disk 320 has a lower surface facing the plurality of unloading devices 100, and the lower surface is arranged to fluctuate in the axial direction of the rotating disk 320 as the rotating disk 320 rotates. Therefore, during the rotation of the rotating disk 320, the unloading device 100 can generate axial movement as the rotating disk 320 rotates, and move from the static position to the working position.

[0133] Specifically, a raised interference portion 321 is provided on the lower surface of the rotating disk 320, and the movement path of the interference portion 321 overlaps with a plurality of unloading devices 100 in a stationary state, and the axial height of the overlapping portion of the interference portion 321 and the unloading device 100 is greater than the axial spacing between the driven gear 110 and the main gear 210 in a stationary state. Therefore, when the interference portion 321 runs through the unloading device 100, it can push the unloading device 100 to move downward until the driven gear 110 is meshed with the main gear 210, thereby realizing the operation of the unloading device 100.

[0134] In this embodiment, the feeding device 100 includes a driven shaft 130 and a main body 120. The driven shaft 130 is inserted into the driven gear 110. The main body 120 is a relatively static part, which is used to store seasoning and perform feeding operations. The driven shaft 130 can move axially relative to the main body 120, and its bottom end can be connected to the main body 120 for rotation prevention, and its top end can be arranged in cooperation with the interference portion 321. The reset member 400 is a spring sleeved on the driven shaft 130, and is used to apply a biasing force to the driven shaft 130 in a certain direction.

[0135] Thus, when the unloading device 100 is in a stationary state, the driven shaft 130 is lifted up by the reset member 400 to release the contact with the main body 120. When the selection structure runs to the corresponding selection position, it acts on the top of the driven shaft 130 to press it down. At this time, the driven gear 110 on the driven shaft 130 is meshed with the driving gear, and the driven shaft 130 is connected to the main body 120 to prevent rotation. Thus, the power of the driving gear can be transmitted to the main body 120 to drive the unloading device 100 to unload. The use of such a structure makes it unnecessary for the unloading device 100 to be lifted and lowered as a whole. On the one hand, it reduces the number of moving parts and reduces the manufacturing difficulty. On the other hand, since the main body 120 is a relatively static structure, it is convenient to seal the seasoning compartment for storing seasonings to prevent the seasonings from getting damp. In addition, such a setting also reduces the contact area of ​​the unloading device 100 when sliding, which is conducive to reducing the sliding friction and preventing the falling device from getting stuck due to increased friction caused by wear after long-term use.

[0136] Combination Figure 5In order to improve the feeding efficiency and prevent the condiment from being hardened, in this embodiment, the main body 120 includes a condiment bin 121, and the driven shaft 130 has an elastic elastic part 131 on the side facing the condiment bin 121. The condiment bin 121 is provided with a protruding interference rib 122, and the elastic part 131 can deform and pass over the interference rib 122 after contacting the interference rib 122. Specifically, when the driven shaft 130 rotates, it drives the elastic part 131 to rotate, and the elastic part 131 hits the interference rib 122 on the condiment bin 121 during the rotation process, and the vibration generated is transmitted to the inside of the condiment bin 121, so that the condiment inside the condiment bin 121 is vibrated and scattered, thereby preventing the condiment from being hardened, and the scattered condiment is easier to feed, thereby improving the feeding efficiency.

[0137] Among them, the seasoning bin 121 includes a platform area 123 and a groove area 124, and the driven shaft 130 is arranged inside the groove area 124. Specifically, the driven shaft 130 is arranged in the groove area 124, that is, a recessed area is arranged on the seasoning bin 121, and the driven shaft 130 is arranged in this recessed area. Therefore, the elastic part 131 located on the driven shaft 130 is also located in the groove area 124, and the interference rib 122 on the seasoning box is also arranged on the inner side wall of the groove area 124 for the elastic part 131 to collide. The above-mentioned structural form can make the overall structure more stable. Compared with setting the rotating part at other positions, such as the inside of the seasoning bin 121, the above-mentioned structural form also has a simple manufacturing process, reduced volume, and reduced risk of interference between debris and the rotating elastic part 131.

[0138] In this embodiment, the surface of the groove area 124 facing the driven shaft 130 is arranged to fit the area swept by the elastic part 131. With the above structure, the contact surface of the elastic part 131 and the interference rib 122 is larger, and a stronger impact vibration effect can be obtained.

[0139] In this embodiment, the material unloading device 100 is divided into two types, one is a grinding quantity control component 500, and the other is a volume quantity control component 600.

[0140] Combination Figure 6 and Figure 7 The grinding control assembly 500 includes an outer sleeve 510 and a grinding cone 520. The inner circumference of the outer sleeve 510 is formed with a coarse grinding thread 511 and a fine grinding thread 512 in sequence along the axial direction. The pitch of the coarse grinding thread 511 is greater than the pitch of the fine grinding thread 512. The grinding cone 520 is arranged inside the outer sleeve 510. The conical surface of the grinding cone 520 is provided with a coarse grinding rib 521 and a fine grinding rib 522.

[0141] The conical surface of the grinding cone 520 and the inner circumference of the outer sleeve 510 form a grinding space, and the two ends of the outer sleeve 510 respectively form a feed port and a discharge port, the coarse grinding ribs 521 are close to the feed port, and the fine grinding ribs 522 are close to the discharge port; the distance between the grinding cone 520 and the outer sleeve 510 gradually decreases from the feed port to the discharge port.

[0142] When in use, large particles of seasoning are put into the grinding space from the feed inlet, and the outer sleeve 510 or the grinding cone 520 is rotated. Under the action of the coarse grinding thread 511 and the coarse grinding rib 521, the large particles of seasoning are squeezed and crushed into small particles of seasoning. Since the distance between the grinding cone 520 and the outer sleeve 510 gradually decreases from the feed inlet to the discharge port, the seasoning particles continue to roll and approach the discharge port after becoming smaller. When the size of the seasoning particles is small enough to roll into the grinding space formed by the fine grinding thread 512 and the fine grinding rib 522, the seasoning particles are further squeezed and crushed. When the distance between the fine grinding thread 512 and the fine grinding rib 522 becomes closer and closer, the seasoning particles are further broken down and become smaller. When the seasoning particles are small enough, they are discharged from the discharge port, completing the entire feeding process. Furthermore, when the grinding control assembly 500 is in operation, each grinding space has seasoning particles of different sizes. Whenever the grinding cone 520 and the outer sleeve 510 rotate relative to each other, a corresponding amount of seasoning will fall from the discharge port.

[0143] The length of the outer sleeve 510 is equal to the height of the grinding cone 520. Through the above arrangement, the outer sleeve 510 and the grinding cone 520 are effectively utilized.

[0144] In this embodiment, there are multiple coarse grinding ribs 521, and the multiple coarse grinding ribs 521 are evenly arranged along the conical surface of the grinding cone 520; and / or there are multiple fine grinding ribs 522, and the multiple fine grinding ribs 522 are evenly arranged along the conical surface of the grinding cone 520. Through the above configuration, multiple coarse grinding ribs 521 and / or fine grinding ribs 522 are provided, so that the seasoning can be ground more finely during the grinding process.

[0145] In this embodiment, the coarse grinding rib 521 connects the upper bottom surface and the lower bottom surface of the grinding cone 520. In this embodiment, the coarse grinding rib 521 is provided to connect the upper and lower bottom surfaces to prevent large-particle seasoning from being missed during the grinding process, and the large-particle seasoning itself cannot enter the grinding space formed by the fine grinding rib 522 and the fine grinding thread 512, resulting in blocking the grinding and feeding process.

[0146] In this embodiment, the coarse grinding ribs 521 and the fine grinding ribs 522 are both obliquely arranged on the conical surface of the grinding cone 520. In this embodiment, the oblique arrangement of the coarse grinding ribs 521 and the fine grinding ribs 522 is conducive to cooperating with the fine grinding threads 512 and the coarse grinding threads 511 to grind the seasoning finely and evenly.

[0147] In this embodiment, the extension direction of the coarse grinding thread 511 is staggered with the extension direction of the coarse grinding rib 521; the extension direction of the fine grinding thread 512 is staggered with the extension direction of the fine grinding rib 522. In this embodiment, the staggered arrangement can grind the seasoning finely and evenly, and can also have the effect of squeezing and crushing the seasoning.

[0148] In this embodiment, the grinding control assembly 500 further includes a first driven shaft 530. The grinding cone 520 is provided with a connecting through hole 531. The first driven shaft 530 can be connected to the connecting through hole 531 and drive the grinding cone 520 to rotate. In this embodiment, the grinding and unloading is performed by driving the grinding cone 520 to rotate.

[0149] The first driven shaft 530 and the connecting through hole 531 are connected without relative rotation. By limiting the non-relative rotation connection between the first driven shaft 530 and the connecting through hole 531, slippage between the first driven shaft 530 and the connecting through hole 531 is prevented to cause energy loss. Specifically, the connecting through hole 531 can be set to a rectangle, and the cross section of the first driven shaft 530 can be set to a corresponding rectangle.

[0150] In this embodiment, the part for storing seasoning in the grinding control assembly 500 is the first seasoning bin 540, and a storage space is formed inside the first seasoning bin 540, and the storage space is connected to the grinding space. The shell of the first seasoning bin 540 can be arranged to be connected to the grinding space to increase the storage space, and the operator can add seasoning once to meet long-term use.

[0151] In this embodiment, the grinding control component 500 further includes a grinding component lock 550 , which is connected to the lower end of the first driven shaft 530 , and is used to axially limit the grinding cone 520 .

[0152] The grinding assembly lock 550 is threadedly connected to the first driven shaft 530. The threaded connection fixes the grinding assembly lock 550 and the first driven shaft 530 together, which has a simple structure and is easy to disassemble. The purpose of fixing and disassembling can be achieved by only tightening or unscrewing the grinding assembly lock 550. In other embodiments, other connection methods may also be used, such as other structures such as buckles.

[0153] Combination Figure 8 , Fig. 9 and Fig.10 The volume control component 600 specifically includes the following parts:

[0154] It includes a second driven shaft 610; an upper drop plate 620, a dosing bin 630 and a lower drop plate 640 which are sequentially arranged and fit together along the axial direction of the second driven shaft 610, the dosing bin 630 is axially connected to the second driven shaft 610, the upper drop plate 620 is provided with an upper drop opening 621, the lower drop plate 640 is provided with a lower drop opening 641, and the lower drop opening 641 and the upper drop opening 621 do not overlap axially; the dosing bin 630 is provided with an axially penetrating dosing hole 631; the second driven shaft 610 can drive the dosing bin 630 to rotate; or, the upper drop plate 620 or the lower drop plate 640 rotates relative to the dosing bin 630; the relative motion trajectory of the dosing hole 631 and the upper drop plate 620 and the lower drop plate 640 overlaps with the upper drop hole and the lower drop hole in sequence.

[0155] Specifically, the upper drop plate 620 and the lower drop plate 640 are attached to the upper and lower end surfaces of the quantitative bin 630, and the lower drop port 641, the upper drop port 621 and the quantitative hole 631 do not overlap axially. When unloading is needed, the upper drop plate 620 is rotated to overlap the upper drop port 621 with the quantitative hole 631 of the quantitative bin 630, so that the seasoning can fall into the quantitative hole 631. The definition of overlapping the upper drop port 621 with the quantitative hole 631 of the quantitative bin 630 here includes but is not limited to complete overlap and partial overlap, both of which can allow the seasoning to fall into the quantitative hole 631. At this time, the quantitative bin 630 or the lower drop plate 640 is rotated, and the seasoning in the quantitative hole 631 will separate from the quantitative hole 631 under the action of gravity and fall from the lower drop port 641 to complete quantitative unloading.

[0156] The assembly has a simple structure, is easy to assemble and understand, is easy to disassemble and clean, and has an extremely low manufacturing cost. Since the upper and lower material drop plates 620, the lower and lower material drop plates 640, and the quantitative bin 630 are in close contact with each other, the seasoning will not be blocked in the material drop structure, and will not cause problems such as difficulty in dropping the material and deterioration of the seasoning due to the agglomeration of the seasoning.

[0157] In other possible implementations, there may be multiple quantitative holes 631 in the quantitative bin 630, and the multiple quantitative holes 631 are arranged circumferentially along the quantitative bin 630. The purpose of providing multiple quantitative holes 631 here is to improve the efficiency of blanking the quantitative bin 630.

[0158] The volume control component 600 also includes a second seasoning bin 650, which forms a feeding space with the upper and lower feeding plates 620, and the feeding space is used to store seasonings. Specifically, the second seasoning bin 650 is arranged around the upper and lower feeding plates 620 to store seasonings. In other embodiments, the second seasoning bin 650 is funnel-shaped, so that the seasonings are more easily accumulated on the upper and lower feeding plates 620, and the seasonings will not remain in the second seasoning bin 650.

[0159] The second seasoning bin 650 further includes a bearing bracket 651, which is slidably connected to the second driven shaft 610. The bearing bracket 651 formed in the second seasoning bin 650 effectively connects the second seasoning bin 650 to the second driven shaft 610, and does not rotate with the second driven shaft 610, thereby improving the overall structural stability.

[0160] The second seasoning bin 650 is relatively stationary with the upper and lower material drop plates 620 and 640. The second seasoning bin 650 is relatively stationary with the upper and lower material drop plates 620 and 640, that is, only when the second driven shaft 610 rotates, the quantitative bin 630 is driven to rotate, and the seasoning inside the second seasoning bin 650 passes through the upper and lower material drop ports 621, the quantitative holes 631 and the lower and lower material drop ports 641 in sequence to complete the quantitative discharge.

[0161] The volume control assembly 600 further includes a control assembly lock 660, which is connected to one end of the second driven shaft 610 close to the lower drop plate 640, and is used to axially limit the lower drop plate 640, the quantitative bin 630, and the upper drop plate 620. Specifically, by arranging the control assembly lock 660 at the lower end of the second driven shaft 610, the lower drop plate 640, the quantitative bin 630, and the upper drop plate 620 are prevented from falling off.

[0162] The control assembly lock 660 is threadedly connected to the second driven shaft 610. The threaded connection fixes the control assembly lock 660 and the second driven shaft 610 together, which has a simple structure and is easy to disassemble. The purpose of fixing and disassembling can be achieved by only tightening or unscrewing the control assembly lock 660. In other embodiments, other connection methods may be used, such as other structures such as buckles.

[0163] like Figure 1 As shown, the volume control assembly 600 further includes a boss group 670, the second driven shaft 610 passes through the boss group 670, and the boss group 670 is disposed between the volume control assembly lock head 660 and the lower drop plate 640. Specifically, the boss group 670 is disposed to abut against the volume control assembly lock head 660 and the lower drop plate 640, so as to prevent the volume control assembly lock head 660 from becoming tighter or looser due to continuous friction between the lower drop plate 640 and the volume control assembly lock head 660 when the volume control assembly lock head 660 and the second driven shaft 610 are threadedly connected.

[0164] The boss group 670 includes a first boss 671 and a second boss 672 that fit each other, the first boss 671 is coaxially slidably connected to the lower plate 640, and the second boss 672 is connected to the volume control component lock 660. As described above, the friction force on the volume control component lock 660 is further reduced.

[0165] like Figure 1As shown, the quantitative bin 630 is provided with a non-circular connecting hole, and the radial cross section of the second driven shaft 610 is a non-circular cross section corresponding to the connecting hole. With the above structure, the second driven shaft 610 can better transmit power to the quantitative bin 630, avoiding power being wasted due to insufficient friction.

[0166] Example 2

[0167] Combination Fig.11 The solid seasoning feeding device 100 provided in this embodiment has different arrangements of the driving mechanism 200 and the selection mechanism 300, as follows:

[0168] The driving mechanism 200 includes a closed-loop transmission chain 230, and the transmission chain 230 is driven by a driving gear 231. A plurality of unloading devices 100 are arranged along the transmission chain 230, and the unloading device 100 includes a transmission wheel 140 capable of transmission cooperation with the transmission chain 230, and the transmission wheel 140 is axially staggered with the transmission chain 230 when the unloading device 100 is in a stationary state, and is transmission-engaged with the transmission chain 230 when the unloading device 100 is in a working state.

[0169] The selection mechanism 300 includes a guide rail placed above the transmission chain 230 and whose trajectory overlaps with the transmission chain 230, and a selection module placed on the guide rail. The rotation module is connected to the transmission chain 230 through a one-way transmission mechanism 310. The selection mechanism 300 is provided with an interference member 330 extending axially toward the unloading device 100. The movement path of the interference member 330 overlaps with multiple unloading devices 100 in a stationary state. The axial height of the overlapping position of the interference member 330 and the unloading device 100 is greater than the axial spacing between the driven gear 110 and the main gear 210 in a stationary state.

[0170] The above structure works as follows:

[0171] S10: The transmission chain 230 rotates forward to drive the selection module to move along the trajectory to the selection position. At this time, the interference member 330 on the selection mechanism 300 contacts the unloading device 100, driving the unloading device 100 to switch from the static state to the working state;

[0172] S20: The transmission chain 230 rotates in the reverse direction, the selection module does not move at this time, and the unloading device 100 operates to perform the unloading operation;

[0173] S30: Repeat the above steps S10 and S20 until all the unloading devices 100 have finished unloading.

[0174] The selection mechanism 300 and the driving mechanism 200 of the above-mentioned solution can also perform the selection operation and the material feeding operation. However, compared with the solution of Example 1, the solution of Example 2 will occupy a larger volume. Therefore, the present invention still preferably adopts the solution of Example 1.
