Description

Technical Field

[0001] The invention relates to a material unloading switching mechanism and a multi-seasoning automatic unloading device. Background Art

[0002] With the accelerated pace of life and the rise of smart kitchens, the market demand for automatic cooking machines is getting higher and higher. However, the functions of automatic cooking machines on the market are relatively simple. Many cooking machines cannot complete a complete cooking process, such as automatically putting in prepared dishes, automatically adding seasonings, and automatically loading dishes. Adding seasonings is a key link, and it is necessary to grasp the timing of adding and accurately control the amount to ensure that the cooked dishes are delicious.

[0003] Since there are many types of seasonings and each seasoning needs to be added in different weights, it is difficult for existing automatic cooking machines to quickly and accurately add multiple seasonings. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the problem in the prior art that it is difficult for automatic cooking machines to quickly and accurately add a variety of seasonings, and to provide a material switching mechanism and a multi-seasoning automatic material feeding device. The mechanism is arranged in the multi-seasoning automatic material feeding device, and can quickly switch among various seasonings and add seasonings with accurate weight.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] The present invention provides a material unloading switching mechanism, which comprises a stepping motor, a linear motor, a ratchet, a pawl, a reset assembly, a driving gear and a driven gear, wherein the upper shaft of the stepping motor is axially connected to the ratchet, and the lower shaft of the stepping motor is connected to the driving gear shaft; the pawl is relatively fixed to the main body of the linear motor; the pawl can be inserted between adjacent one-way teeth of the ratchet, and the reset assembly is connected to the driven gear; the output shaft of the linear motor faces the driven gear, and the driven gear is used to drive the material unloading assembly to unload; the reset assembly provides an upward force to the driven gear; the output shaft of the linear motor can push the driven gear, so that the driven gear and the driving gear are in the same horizontal plane and meshed with each other; when the driven gear is not subjected to the thrust from the output shaft, the driven gear is located above the driving gear.

[0007] In this case, the linear motor is driven to rotate by a stepper motor to select the required seasoning, and the linear motor pushes the driven gear to mesh with the driving gear. At this time, the driving motor rotates in the opposite direction and drives the driving gear to rotate the driving gear and the driven gear. The driven gear drives the unloading assembly to unload the seasoning. When there is a need to unload seasoning, different driven gears can be selected according to the pre-set degree to complete the unloading, so that the cooking machine can quickly switch between various seasonings and add seasonings with accurate weight, which improves convenience and functionality.

[0008] Preferably, the material unloading switching mechanism further comprises a ratchet base and a linear motor bracket, the ratchet pawl is fixed to the ratchet base, the ratchet base is fixed to the linear motor bracket, and the body of the linear motor is fixedly mounted on the linear motor bracket.

[0009] In the present case, by setting up a ratchet base and a linear motor bracket, the linear motor can be supported and fixed, while also preventing the pawl from directly acting on the linear motor. Instead, the pawl is fixed to the ratchet base and the ratchet base is connected to the linear motor bracket to transmit the force from the pawl to the linear motor, effectively reducing the situation where the linear motor is insufficiently supported and subjected to pressure for a long time.

[0010] Preferably, the material unloading switching mechanism also includes an annular support frame, which surrounds the linear motor bracket, and the edge of the linear motor bracket forms a support foot extending downward, and the support foot is supported on the annular support frame.

[0011] In this case, by providing an annular support frame, the linear motor bracket is effectively supported during the rotation process.

[0012] Preferably, the annular support frame is provided with a limiting ring, which protrudes from the upper surface of the annular support frame, and the inner circumference of the limiting ring is used to resist the supporting foot.

[0013] In this case, the limit ring can play a role of radial support for the right angle of the linear motor bracket during its rotation, thereby preventing the linear motor bracket from being thrown away due to the centrifugal force during its rotation.

[0014] Preferably, the material unloading switching mechanism also includes a driven shaft, which is axially connected to the driven gear, and the output shaft of the linear motor is arranged facing the upper end surface of the driven shaft, and the output shaft of the linear motor is used to drive the driven shaft to move axially.

[0015] In this case, a driven shaft is arranged on the driven gear. Compared with the output shaft of the linear motor directly pushing the driven gear, it can avoid the output shaft generating friction on the driven gear when the driven gear rotates.

[0016] Preferably, the material unloading switching mechanism also includes an ejection end head, which is fixed on the output shaft of the linear motor and is provided with a contact surface that contacts the upper end surface of the driven shaft; when the ejection end head contacts the upper end surface of the driven shaft, the contact surface covers the upper end surface of the driven shaft.

[0017] In this case, in order to reduce the difficulty of docking the linear motor output shaft and the driven shaft, a push-out end is provided on the output shaft to make it easier to push the driven shaft.

[0018] Preferably, the material unloading switching mechanism includes a driven gear upper cover and a housing bottom, the driven shaft passes through the driven gear upper cover and the housing bottom, and a bearing is provided between the driven shaft and the driven gear upper cover and the housing bottom.

[0019] In this case, without affecting the rotation of the driven shaft and the driven gear, a driven gear upper cover and a housing bottom are provided to support and protect the driven shaft and the driven gear.

[0020] Preferably, there are multiple driven gears, and the multiple driven gears are distributed in the circumference of the driving gear.

[0021] In this case, a plurality of driven gears are arranged to meet the feeding requirements of a variety of seasonings.

[0022] Preferably, the reset assembly includes a driven gear support frame, a shell bottom and a compression spring, the driven gear support frame is arranged between the bottom of the driven gear and the shell bottom, the driven gear support frame is slidingly connected to the driven gear, the shell bottom is relatively fixed to the driving gear, and the compression spring is arranged between the driven gear support frame and the shell bottom.

[0023] In this case, the compression spring is arranged between the driven gear support frame and the bottom of the housing, which avoids direct contact and friction between the spring and the driven gear, increases the life of the gear and the spring, and also increases the durability of the equipment.

[0024] Preferably, the material unloading switching mechanism further comprises a driven gear upper cover, which is arranged above the driven gear and is used to limit the axial movement of the driven gear.

[0025] In this case, in order to prevent the driven gear from being pushed upward without limit by the spring, a driven gear upper cover is provided to limit the axial movement of the driven gear.

[0026] A multi-seasoning automatic unloading device includes multiple unloading components, which are used to drive the unloading of seasonings; the aforementioned unloading switching mechanism; the number of driven gears of the unloading switching mechanism is multiple, each unloading component corresponds to a driven gear, and the driven gear can drive the corresponding unloading component to unload.

[0027] In this case, the unloading action is completed by setting up multiple unloading components and cooperating with the unloading switching components.

[0028] Preferably, each driven gear is provided with a corresponding driven shaft, which is axially connected to the driven gear; the unloading assembly also includes a screw and a unloading box, the screw is fixedly connected to the driven shaft, and the unloading box is arranged around the screw; the screw rotates under the drive of the driven gear, driving the seasoning in the unloading box to be unloaded.

[0029] In this case, by setting the screw rod to cooperate with the driven shaft, when the driven shaft is driven to rotate by the driven gear, the driven shaft drives the screw rod to rotate, and the screw rod drives the seasoning in the discharge box to complete the discharge action.

[0030] Preferably, an axial hole is provided at the upper end of the screw rod, and the axial hole is used to cooperate with the driven shaft.

[0031] In this case, the axial hole provided in the screw rod allows the driven shaft to be inserted, and when the driven shaft rotates, the screw rod is driven to rotate.

[0032] On the basis of being in accordance with the common sense in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present invention.

[0033] The positive and progressive effects of the present invention are:

[0034] The unloading switching mechanism of the present invention can select different driven gears to rotate, while the other driven gears remain stationary. The unloading device using the unloading switching mechanism can quickly switch among various seasonings and add seasonings with accurate weight. Only two driving components are used to achieve automatic unloading control of a variety of different solid seasonings, and the cost is relatively low. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", "front", "back" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0061] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0062] like Figure 1 and 2 As shown, a multi-seasoning automatic unloading device includes multiple unloading components and an unloading switching mechanism. The unloading components are used to drive the unloading of seasonings; the number of driven gears 6 of the unloading switching mechanism is multiple, each unloading component corresponds to a driven gear 6, and the driven gear 6 can drive the corresponding unloading component to unload. The driven gear 6 can drive the unloading component to unload by rotating.

[0063] Each driven gear 6 is provided with a corresponding driven shaft 12, and the driven shaft 12 is connected to the driven gear 6 by an axis; the unloading assembly also includes a screw 18 and an unloading box 19, the screw 18 is fixedly connected to the driven shaft 12, and the unloading box 19 is arranged around the screw 18; the screw 18 is driven by the driven gear 6 to rotate, driving the seasoning in the unloading box 19 to be unloaded. When the unloading assembly is the screw 18, the screw 18 and the driven shaft 12 are directly fixed, and they can rotate together to achieve the purpose of unloading.

[0064] The upper end of the screw rod 18 is provided with an axial hole, and the axial hole is used to cooperate with the driven shaft 12, thereby providing a cooperation mode between the screw rod 18 and the driven shaft 12.

[0065] When using the present material unloading switching mechanism, the required material is determined first, the upper shaft of the stepper motor 1 rotates, and with the cooperation of the ratchet 3 and the pawl 4, the ratchet base 7 is driven to rotate, the ratchet base 7 drives the linear motor bracket 8 to rotate, and the linear motor bracket 8 drives the linear motor 2 to rotate. When it rotates to the top of the required unloading box 19, the linear motor 2 extends the output shaft 11, and the push-out end 13 located on the output shaft 11 pushes the driven shaft 12 coaxial with the driven gear 6 to overcome the elastic force of the compression spring 17 from the bottom of the driven shaft 12, and pushes the driven gear 6 to the same plane as the driving gear 5. At this time, the driving gear 5 and the driven gear 6 are in the same plane. The gears 6 are meshed, and the stepper motor 1 rotates in the opposite direction. The ratchet 3 on the upper shaft of the stepper motor 1 will not drive the linear motor 2 to rotate due to its own unidirectionality, while the driving gear 5 on the lower shaft of the stepper motor 1 drives the driven gear 6 to rotate, and the driven gear 6 drives the driven shaft 12 coaxial therewith to rotate, and the driven shaft 12 drives the screw 18 located on its lower end face to rotate, and the screw 18 is located in the discharge box 19, driving the seasoning in the discharge box 19 to be discharged. After the discharge is completed, the linear motor 2 retracts its output shaft 11, and the driven gear 6 returns to the initial position under the action of the compression spring 17, forming a complete discharge process.

[0066] like Figures 1 to 5 As shown, a material unloading switching mechanism includes a stepper motor 1, a linear motor 2, a ratchet 3, a pawl 4, a reset assembly, a driving gear 5 and a driven gear 6, wherein the upper shaft of the stepper motor 1 is axially connected to the ratchet 3, and the lower shaft of the stepper motor 1 is axially connected to the driving gear 5; the pawl 4 is relatively fixed to the main body of the linear motor 2; the pawl 4 can be inserted between adjacent one-way teeth of the ratchet 3, and the reset assembly is connected to the driven gear 6; the output shaft 11 of the linear motor 2 faces the driven gear 6, and the driven gear 6 is used to drive the unloading assembly to unload; the reset assembly provides an upward force to the driven gear 6; the output shaft 11 of the linear motor 2 can push the driven gear 6, so that the driven gear 6 and the driving gear 5 are in the same horizontal plane and meshed with each other; when the driven gear 6 is not subjected to the thrust from the output shaft 11, the driven gear 6 is located above the driving gear 5.

[0067] The upper shaft of the stepper motor 1 rotates forward, and the linear motor 2 is rotated to the top of the driven gear 6 through the cooperation of the ratchet 3 and the pawl 4. At this time, the output shaft 11 of the linear motor 2 pushes the driven gear 6 to overcome the force of the reset assembly, and presses the driven gear 6 to the same plane as the driving gear 5. At this time, the driven gear 6 is meshed with the driving gear 5, and the stepper motor 1 rotates in the opposite direction. The ratchet 3 connected to the upper shaft of the stepper motor 1 does not cooperate with the pawl 4 when the stepper motor 1 rotates in the opposite direction. Therefore, the linear motor 2 located above the stepper motor 1 remains stationary, and the driving gear 5 connected to the lower shaft of the stepper motor 1 drives the driven gear 6 meshed therewith to rotate, and the driven gear 6 drives the blanking assembly connected thereto, and the blanking assembly completes the blanking. After the blanking is completed, the linear motor 2 retracts the output shaft 11, and the driven gear 6 loses the pressure from the linear motor 2, and the reset assembly pushes the driven gear 6 to the initial position.

[0068] like Figure 3 and 4 As shown, the material switching mechanism further includes a ratchet base 7 and a linear motor bracket 8, the pawl 4 is fixed to the ratchet base 7, the ratchet base 7 is fixed to the linear motor bracket 8, and the main body of the linear motor 2 is fixedly mounted on the linear motor bracket 8. When the ratchet 3 rotates forward to clamp the pawl 4, because the pawl 4 is fixed to the ratchet base 7, the pawl 4 pushes the ratchet base 7 to rotate, and the ratchet base 7 drives the linear motor bracket 8 to rotate, thereby achieving the purpose of rotating the linear motor 2.

[0069] The material unloading switching mechanism further includes an annular support frame 9, which surrounds the linear motor support 8. The edge of the linear motor support 8 forms a support leg extending downward, and the support leg is supported on the annular support frame 9. The annular support frame 9 is provided for the linear motor support 8 so that the linear motor support 8 has at least two fulcrums to prevent it from falling under the action of gravity.

[0070] The annular support frame 9 is provided with a limiting ring 10, which protrudes from the upper surface of the annular support frame 9, and the inner circumference of the limiting ring 10 is used to resist the support foot. At the same time, a protrusion is provided on the annular support frame 9, so that the support foot of the linear motor bracket 8 also provides a support surface in its radial direction.

[0071] like Figure 1 and 2 As shown, the material switching mechanism further includes a driven shaft 12, which is axially connected to the driven gear 6, and the output shaft 11 of the linear motor 2 is arranged facing the upper end surface of the driven shaft 12, and the output shaft 11 of the linear motor 2 is used to push the driven shaft 12 to move axially. The driven shaft 12 is arranged to pass through the driven gear 6, and the driven shaft 12 cooperates with the output shaft 11 of the linear motor 2, so that the output shaft 11 is prevented from directly contacting the driven gear 6.

[0072] The material switching mechanism further includes a push-out end 13, which is fixed to the output shaft 11 of the linear motor 2 and is provided with a contact surface that contacts the upper end surface of the driven shaft 12; when the push-out end 13 contacts the upper end surface of the driven shaft 12, the contact surface covers the upper end surface of the driven shaft 12. In order to prevent the output shaft 11 of the linear motor 2 from failing to accurately push the driven shaft 12, the push-out end 13 is provided to expand the contact area of ​​the output shaft 11 so that it can better push the driven shaft 12.

[0073] like Figure 5 As shown, the unloading switching mechanism includes a driven gear upper cover 14 and a housing bottom 15, and the driven shaft 12 passes through the driven gear upper cover 14 and the housing bottom 15. A bearing is arranged between the driven shaft 12 and the driven gear upper cover 14 and the housing bottom 15. The driven gear 6 is surrounded to prevent the machine from being damaged by entering the meshing area, and the driven gear 6 will not rotate with the driven gear 6 due to the bearing connection.

[0074] There are multiple driven gears 6, which are distributed around the driving gear 5. When there is a need to discharge multiple spices, multiple driven gears 6 can be installed around the driving gear 5 to achieve the function of automatically discharging multiple spices.

[0075] like Figure 5 As shown, the reset assembly includes a driven gear support frame 16, a housing bottom 15 and a compression spring 17. The driven gear support frame 16 is disposed between the bottom of the driven gear 6 and the housing bottom 15. The driven gear support frame 16 is slidably connected to the driven gear 6. The housing bottom 15 and the driving gear 5 are relatively fixed. The compression spring 17 is disposed between the driven gear support frame 16 and the housing bottom 15. The compression spring 17 is disposed between the bottom of the driven gear support frame 16 below the driven gear 6 and the housing bottom 15. On the one hand, it can still provide an upward force to the driven gear 6, and on the other hand, it avoids direct contact between the driven gear 6 and the compression spring 17.

[0076] like Figure 5 As shown, the material unloading switching mechanism further includes a driven gear upper cover 14, which is disposed above the driven gear 6 and is used to limit the axial movement of the driven gear 6. When the reset assembly provides a continuous upward force, the axial movement of the driven gear 6 is limited to a limited range.

[0077] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
