Description

Technical Field

[0001] The invention relates to the field of household appliances, and in particular to a feeding and turning device and cooking equipment. Background Art

[0002] With the development of society and the advancement of technology, the automation of household appliances has become a trend of future development. At present, in the field of food processing, the automation of food processing equipment such as dough mixers, noodle presses and dumpling makers has been widely used. In the field of cooking, household appliances such as automatic stir-fry machines, which have a large number of materials and relatively complex cooking processes, are also gradually being promoted and used. There are many structures of automatic stir-fry machines on the market, but for fully automatic stir-fry machines, it is generally necessary to set up multiple feeding boxes. The feeding mechanism puts the raw materials in different feeding boxes into the wok at different times according to the predetermined cooking program. This requires the feeding mechanism to be able to clamp the feeding box after the feeding box reaches the predetermined position, put the raw materials in the feeding box into the wok, and then send the feeding box back to its original position.

[0003] In the existing automatic stir-frying machines, there are two main ways to feed the material in the feeding box. One is to use an electromagnet to adsorb and flip the material in the feeding box to put it into the wok. In this way, the adsorption of the electromagnet is unreliable and slow; further, the power cord of the electromagnet is prone to poor contact or breakage during repeated flipping. The other is to use a mechanical arm to grab, which is expensive and occupies a large space, greatly increasing the manufacturing cost of the automatic stir-frying machine. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a feeding and turning device and a cooking device with fast feeding speed and simple structure.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a feeding and flipping device, which includes a driving motor, a rotating shaft and a locking assembly. The rotating shaft is connected to the driving motor and rotates under the action of the driving motor. The locking assembly includes a connecting member, a locking member and a releasing member. The connecting member is fixedly connected to the rotating shaft. The locking member includes a main body, a locking hook formed at one end of the main body, and a releasing triggering member formed at the other end of the main body. The main body is rotatably connected to the connecting member and a rotating fulcrum is formed at the connection. The locking hook and the releasing triggering member rotate around the rotating fulcrum; when feeding, the locking hook is locked with the card slot on the feeding box. The releasing member is arranged opposite to the releasing triggering member, and after the feeding is completed, it abuts against the releasing triggering member to make the locking member rotate around the rotating fulcrum, and the locking hook is separated from the card slot on the feeding box.

[0006] According to one embodiment of the present invention, the locking hook portion protrudes from the main body portion, and a limiting step is formed at the connection between the locking hook portion and the main body portion. In the locked state, the limiting step abuts against the inner side wall of the slot of the feeding box close to the feeding and flipping device, and the surface of the locking hook portion has an inclined guide surface along the direction of extending into the slot on the feeding box.

[0007] According to one embodiment of the present invention, the unlocking piece and the unlocking trigger part are fixed correspondingly thereunder. After the feeding is completed, the rotating shaft drives the locking piece and the feeding box to rotate in the direction opposite to the feeding direction. The unlocking trigger part abuts against the unlocking piece to make the locking piece rotate around the rotating fulcrum, and the locking hook part is separated from the slot on the feeding box.

[0008] According to an embodiment of the present invention, the unfastening trigger portion includes a connecting section and a trigger section, the connecting section is connected to the main body and extends to the side where the unfastening piece is located, and the trigger section is arranged on the connecting section.

[0009] According to one embodiment of the present invention, the trigger segment is fixed to the connecting segment or is integrally formed with the connecting segment, the cross-sectional profile of the trigger segment is a circular arc or an elliptical arc, and the release member has a curved surface corresponding to the outer profile of the trigger segment. As the rotating shaft rotates, the trigger segment slides relative to the surface of the release member and is squeezed by the release member to rotate around the rotating fulcrum.

[0010] According to an embodiment of the present invention, the trigger section is rotatably connected to the connecting section. As the rotating shaft rotates, the trigger section rolls relative to the surface of the unlocking member and is squeezed by the unlocking member to rotate around the rotation fulcrum.

[0011] According to one embodiment of the present invention, the unfastening member and the unfastening trigger part are fixed correspondingly thereunder and are a retractable structure. After the feeding is completed, the rotating shaft rotates to the initial position, the unfastening member is extended to abut against the unfastening trigger part and make it rotate around the rotating fulcrum, and the locking hook part is separated from the slot on the feeding box.

[0012] According to one embodiment of the present invention, the feeding and turning device also includes at least one positioning member fixedly connected to the rotating shaft, and the discharge box has a positioning hole arranged corresponding to the at least one positioning member. When feeding, each positioning member penetrates the corresponding positioning hole.

[0013] According to one embodiment of the present invention, the feeding and flipping device also includes a flip plate fixed to a rotating shaft and at least one flexible buffer column fixed to the flip plate, the connecting piece is fixed to the flip plate and is located on one side of the at least one flexible buffer column, when feeding, the feeding box squeezes at least one flexible buffer column under the action of external thrust and locks with the locking hook part; when unlocking, at least one flexible buffer column resets and pushes the feeding box out of the locking hook part.

[0014] Correspondingly, the present invention also provides a cooking device, which includes the above-mentioned material feeding and turning device.

[0015] In summary, in the feeding and flipping device and cooking equipment provided by the present invention, the locking member is connected to the rotating shaft through a connecting member and rotates with the rotating shaft, and the locking member is provided with a locking hook portion. After the locking hook portion is clamped with the card slot on the feeding box, the feeding box is driven to rotate with the rotating shaft, so that the material in the feeding box is fed into the pot. After the feeding is completed, the rotating shaft drives the locking member and the feeding box to rotate in the opposite direction. At this time, the unlocking member abuts against the unlocking trigger portion to make the locking member rotate around the rotating fulcrum on the main body, and the locking hook portion tilts up and disengages from the feeding box. In the feeding and flipping device provided by the present invention, the setting of the rotating shaft and the locking hook portion enables the feeding box to rotate with the rotating shaft to realize feeding, and the setting of the unlocking trigger portion and the unlocking member realizes the separation of the feeding box and the locking hook portion after the feeding is completed to carry out the next feeding. The entire feeding and turning device has a compact structure and can realize the unlocking of the lock hook and the feeding box during the rotation and resetting process after the feeding is completed. The two are carried out synchronously, which greatly improves the turning and feeding rate. The locking component with a fully mechanical structure greatly improves the safety and reliability of the entire device.

[0026] Embodiment 1

[0027] like Figure 1 As shown, the feeding and flipping device 10 provided in this embodiment includes a driving motor 1, a rotating shaft 2 and a locking assembly 3. The rotating shaft 2 is connected to the driving motor 1 and rotates under the action of the driving motor 1. The locking assembly 3 includes a connecting member 31, a locking member 32 and a releasing member 33. The connecting member 31 is fixedly connected to the rotating shaft 2. The locking member 32 includes a main body 321, a locking hook portion 322 formed at one end of the main body 321, and a releasing trigger portion 323 formed at the other end of the main body 321. The main body 321 is rotatably connected to the connecting member 31 and a rotating fulcrum A is formed at the connection. The locking hook portion 322 and the releasing trigger portion 323 rotate around the rotating fulcrum; when feeding, the locking hook portion 322 is locked with the card slot 201 on the feeding box 20. The release member 33 is arranged opposite to the release trigger portion 323 . After the feeding is completed, the release trigger portion 323 abuts against the lock member 32 to rotate around the rotation fulcrum, and the lock hook portion 322 is separated from the slot 201 on the feeding box.

[0028] In this embodiment, if Figure 1 and Figure 3 As shown, the middle of the main body 321 has a mounting portion protruding toward the side where the connecting member 31 is located, and the mounting portion is rotatably connected to the connecting member 31 through a pin shaft and a torsion spring sleeved on the pin shaft. However, the present invention does not make any limitation to this.

[0029] like Figures 3 to 5 As shown, the lock hook portion 322 protrudes from the main body 321, and the connection between the lock hook portion 322 and the main body 321 forms a limiting step 3221. In the locked state, the limiting step 3221 abuts against the inner side wall of the slot 201 of the feeding box close to the feeding and turning device. Further, along the direction of extending into the slot 201 on the feeding box, the surface of the lock hook portion 322 has an inclined guide surface 3222. The setting of the guide surface 3222 makes it possible for the feeding box to move along the guide surface 3222 and press down the lock hook portion 322 when an external force pushes the feeding box. When the slot 201 at the bottom of the feeding box is opposite to the lock hook portion 322, the lock hook portion 322 is clamped into the slot 201 to clamp the feeding box 20. However, the present invention does not impose any limitation on the structure of the lock hook portion. In other embodiments, the lock hook portion may not be provided with a guide surface. In this structure, when the feeding box is pushed close to the lock hook, the lock member abuts against the unlocking trigger to make the lock hook tilt up. When the feeding box is pushed into place, the lock hook is locked with the slot thereon. Figure 4 and Figure 4A As shown, the bottom of the feeding box is also provided with a guide groove 203.

[0030] In this embodiment, if Figure 1 and Figure 6 As shown, the release member 33 and the release trigger part 323 are fixed correspondingly below it. After the feeding is completed, the rotating shaft 31 drives the lock member 32 and the feeding box 20 to rotate in the direction opposite to the feeding direction. During the rotation process, the release trigger part 323 abuts against the release member 33 to make the lock member 32 rotate around the rotation fulcrum A, and the lock hook part 322 is separated from the card slot 201 on the feeding box, and the feeding box falls into the recovery tank under the action of its own gravity. In this structure, the release of the feeding box is completed during the process of its falling recovery. The fusion of the two processes greatly saves the efficiency of feeding, especially when the flip feeding device provided by this embodiment is applied to the feeding of multiple materials or multiple woks, the increase in the feeding rate can meet the feeding time requirements, which not only greatly improves the efficiency of the automatic cooking machine, but also greatly reduces the volume and cost of the entire equipment when multiple woks share one flip feeding device.

[0031] However, the present invention does not make any limitation to this. In other embodiments, a release member and a release trigger portion may be fixed correspondingly thereunder and may be a retractable structure. After the feeding is completed, the rotating shaft rotates to the initial position, the release member extends to abut against the release trigger portion and causes it to rotate around the rotation fulcrum, and the lock hook portion is separated from the card slot on the feeding box, and then the feeding box can be taken away by a robot.

[0032] like Figure 1 and Figure 2 As shown, the feeding and turning device further comprises a turning plate 4 fixed to the rotating shaft 1 and at least one flexible buffer column 5 fixed to the turning plate, and the connecting member 31 is fixed to the turning plate 4 and is located on one side of the at least one flexible buffer column 5. In this embodiment, the number of the flexible buffer columns 5 is two and they are respectively located on both sides of the connecting member 31. However, the present invention does not make any limitation to this. In other embodiments, the number of the flexible buffer columns may be one or more than three.

[0033] When feeding, the feeding box squeezes the two flexible buffer columns 5 under the action of external thrust, and the flexible buffer columns 5 buffer and shrink due to being squeezed. When unfastening, when the lock hook portion 322 is separated from the slot 201 on the feeding box, the flexible buffer column 5 is reset and the reset generates an outward thrust and acts on the feeding box, so that the feeding box can quickly separate from the lock hook portion, further improving the feeding speed.

[0034] like Figure 1 and Figure 3As shown, the unfastening trigger part 323 includes a connecting section 3231 and a trigger section 3232. The connecting section is connected to the main body 322 and extends to the side where the unfastening member 33 is located. The trigger section 3232 is arranged on the connecting section 3231. In this embodiment, the trigger section 3232 and the connecting section 3231 are integrally formed. The cross-sectional profile of the trigger section 3232 is a circular arc or an elliptical arc. The unfastening member 33 has a curved surface corresponding to the outer contour of the trigger section. With the rotation of the rotating shaft, the trigger section 3232 slides relative to the surface of the unfastening member 33 and is squeezed by the unfastening member to rotate around the rotation fulcrum A. The cross-sectional profile of the trigger section 3232 and the curved surface profile of the unfastening member 33 enable the trigger section 3232 to slide smoothly along the surface of the unfastening member 33 when abutting against the unfastening. This setting not only makes the unfastening smooth and free of jamming, but also the smooth sliding of the curved surface can reduce the wear between the two to increase the service life of the locking member 32 and the unfastening member 33.

[0035] In this embodiment, the feeding and turning device also includes two positioning members 6 fixed on the turning plate 4. The discharge box 20 has positioning holes 202 corresponding to the two positioning members 6. When feeding, each positioning member 6 penetrates the corresponding positioning hole. The setting of the positioning members 6 enables the feeding box to accurately cooperate with the locking hook portion 322 when moving, and this positioning method is very simple and accurate. Furthermore, in this embodiment, in order to achieve the disengagement of the locking hook portion and the recovery of the feeding box, a rotation space needs to be configured on the side of the locking hook portion close to the feeding box. At this time, the positioning member 6 provides a track for the movement of the feeding box while achieving positioning, and there is no need to set a moving track for the feeding box separately, which greatly simplifies the structure of the device. However, the present invention does not make any limitation to this.

[0036] Correspondingly, this embodiment further provides a cooking device, which includes the above-mentioned material feeding and turning device 10 and at least one cooking pot 30 arranged on one side of the material feeding and turning device 10.

[0037] In this embodiment, the cooking device is an automatic cooking machine and the automatic cooking machine only includes a cooking pot 30. However, the present invention does not make any limitation to this. In other embodiments, any cooking device that needs to feed can use the feeding turning device provided in this embodiment.

[0038] Embodiment 2

[0039] This embodiment is basically the same as the first embodiment and its variations, except that: Figure 8As shown, the trigger section 3232 is rotatably connected to the connecting section 3231 via the rotating shaft 324. As the rotating shaft 2 rotates, the trigger section 3232 gradually approaches the unlocking member 31. After the trigger section 3232 abuts against the unlocking member 31, it rolls relative to the surface of the unlocking member 31 and is squeezed by the unlocking member 31 to rotate around the rotating fulcrum A. In this structure, when unlocking, the trigger section 3232 and the unlocking member 31 are in rolling contact, and rolling friction is generated between the two. Not only is the friction force smaller, the unlocking is smoother and faster, but also the friction loss between the two will be smaller, further improving the service life of the two.

[0040] In summary, in the feeding and flipping device and cooking equipment provided by the present invention, the locking member is connected to the rotating shaft through a connecting member and rotates with the rotating shaft, and the locking member is provided with a locking hook portion. After the locking hook portion is clamped with the card slot on the feeding box, the feeding box is driven to rotate with the rotating shaft, so that the material in the feeding box is fed into the pot. After the feeding is completed, the rotating shaft drives the locking member and the feeding box to rotate in the opposite direction. At this time, the unlocking member abuts against the unlocking trigger portion to make the locking member rotate around the rotating fulcrum on the main body, and the locking hook portion tilts up and disengages from the feeding box. In the feeding and flipping device provided by the present invention, the setting of the rotating shaft and the locking hook portion enables the feeding box to rotate with the rotating shaft to realize feeding, and the setting of the unlocking trigger portion and the unlocking member realizes the separation of the feeding box and the locking hook portion after the feeding is completed to carry out the next feeding. The entire feeding and turning device has a compact structure and can realize the unlocking of the lock hook and the feeding box during the rotation and resetting process after the feeding is completed. The two are carried out synchronously, which greatly improves the turning and feeding rate. The locking component with a fully mechanical structure greatly improves the safety and reliability of the entire device.

[0041] Although the present invention has been disclosed as above by the preferred embodiment, it is not intended to limit the present invention. Anyone familiar with this technology can make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection required by the claims.
