[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] like Figure 1 As shown, an embodiment of the present invention provides a metering feeder, which includes: a base 10, a horizontal pivoting power device 20, a first feeding device 30, a second feeding device 40, a metering device 60 and a water replenishing device 50.

[0057] The base 10 is used to integrate other structures of the metering feeder of the present invention, which includes: a hollow column structure 11 or a column structure 11 with a counterweight inside, the bottom of the column structure 11 has a supporting foot 12, reinforcing ribs 13 are connected between the column structure 11 and the supporting foot 12 at the bottom, and the supporting foot 13 is provided with holes for installing and fixing the base 10.

[0058] The horizontal pivoting power device 20 is used to drive the first feeding device 30, the second feeding device 40 and the water replenishing device 50 to pivot as a whole within a plane.

[0059] The horizontal pivoting power device 20 includes: a first housing 21 , a first rotating motor, a first reducer, a primary rotating arm 22 , a second housing 23 , a second rotating motor and a secondary rotating arm 24 .

[0060] The first housing 21 is mounted on the side of the base 10. The first rotating motor is contained in the first housing 21. The output end of the first rotating motor is connected to one end of the first rotating arm 22 through the first reducer. In this way, driven by the first rotating motor, the first rotating arm 22 can be driven to pivot in the horizontal plane. The other end of the first rotating arm 22 is connected to the second housing 23. The second rotating motor is contained in the second housing 23. The output end of the first rotating motor is connected to one end of the second rotating arm 24 through the second reducer. In this way, driven by the second rotating motor, the second rotating arm 24 can be driven to pivot in the horizontal plane. The other end of the second rotating arm 24 is connected to the base 36 where the first feeding device 30 is located.

[0061] The first feeding device 30 is used to store the seasoning to be fed, and to feed the fed seasoning to the moving metering device 60. The first feeding device 30 is separately provided from the second feeding device 40, and can be installed on the top of the base 10. In other embodiments, the first feeding device 30 can also be separately provided from the base 10, and is located within the movement range of the metering device 60.

[0062] like Figure 2 , 3 As shown, the first feeding device 30 includes: a seasoning barrel 31, a barrel fixing seat 32, a circulating pivoting power mechanism 33, a positioning mechanism 34 and a feeding mechanism 35.

[0063] The circular pivoting power mechanism 33 is used to drive each seasoning barrel 31 to perform circular rotational motion.

[0064] Specifically, the cyclic pivoting power mechanism 33 includes: a cyclic pivoting motor 331, an annular rack 332, and a ball clamping structure 333. The cyclic pivoting motor 331 is arranged vertically and mounted on the base 36 through a motor fixing bracket 334. A driving gear 335 is mounted at the output end of the cyclic pivoting motor 331, and the driving gear 335 is arranged horizontally and can be synchronously pivoted with the operation of the cyclic pivoting motor 331.

[0065] In order to cooperate with the assembly of the driving gear 335, the motor fixing frame 334 includes: a U-shaped fixing frame body 3341, a vertical plate 3342 arranged at the top of the U-shaped fixing frame body 3341, and a support 3343 arranged at the bottom of the U-shaped fixing frame body 3341. The U-shaped fixing frame body 3341 is arranged horizontally, the circular pivoting motor is installed at the top of the U-shaped fixing frame body 3341, and the driving gear 335 is accommodated in the space surrounded by the U-shaped fixing frame body 3341.

[0066] The annular rack 332 is located at the periphery of the circulating pivot motor 331, and a plurality of continuously arranged meshing teeth are formed on a side thereof facing the circulating pivot motor 331. The driving gear 335 can mesh with the annular rack 332, so that when the circulating pivot motor 331 is working, the annular rack 332 can be driven to pivot synchronously. In one embodiment, the annular rack 332 is locked and fixed to the inner side surface of the barrel fixing seat 32 by a plurality of pins 3321.

[0067] The ball clamping structure 333 is used to keep the above-mentioned annular rack 332 stable. The ball clamping structure 333 specifically includes: an upper clamping arm 3331 and a lower support 3332. There are a plurality of upper clamping arms 3331, and each upper clamping arm 3331 is circumferentially spaced and distributed on the inner side of the annular rack 332. The lower end of any upper clamping arm 3331 is fixed to the base 36, and an upper ball is arranged on the upper end, and the upper ball can slide relatively along the slide groove on the upper surface of the annular rack 332. The lower support 3332 is correspondingly arranged in an annular shape, which is fixed to the base 36 and is located below the annular rack 332. A plurality of lower balls are arranged circumferentially spaced on the top surface of the lower support 3332, and each lower ball can slide relatively along the slide groove on the lower surface of the annular rack 332. With such an arrangement, under the clamping guidance of the plurality of upper balls and the lower balls, the annular rack 332 can maintain stable pivoting motion within a certain horizontal plane.

[0068] There are multiple seasoning barrels 31, and they perform cyclic rotation under the drive of the cyclic pivoting power mechanism 33. Each seasoning barrel 31 can also be set as a solid barrel and a liquid barrel according to the type of seasoning to be stored, and the solid barrel can be set as a different barrel mechanism according to the size of the solid seasoning particles. In order to cooperate with each seasoning barrel 31 to perform cyclic rotation, the barrel fixing seat 32 is set to a cylindrical shape, and each seasoning barrel 31 is circumferentially mounted on the outer surface of the barrel fixing seat 32. Correspondingly, a hook or a hanging hole is set on the outer surface of the barrel fixing seat 32, and a matching hanging hole or hook is correspondingly set on the back of each seasoning barrel 31.

[0069] The annular rack 332 is fixed to the inner side of the barrel fixing seat 32, so that the first feeding device 30 can perform a cyclic rotation under the drive of the cyclic pivoting power mechanism 33. In addition, in order to cooperate with the feeding of the seasoning in each seasoning barrel 31, a notch 361 is provided on the base 36. In this way, when the corresponding barrel moves to the top of the notch 361 with the rotation of the barrel fixing seat 32, the seasoning stored therein can be discharged and fall through the notch 361. Correspondingly, the notch 361 is also connected to a feeding channel 362.

[0070] like Figure 4 As shown, the seasoning barrel 31 specifically includes: a liquid barrel 310, a first solid barrel 320 and a second solid barrel 330. The number of the above-mentioned seasoning barrels 31 is set according to demand, and they are circumferentially mounted on the outer surface of the barrel fixing seat 32.

[0071] The liquid material barrel 310 is used to store liquid seasonings so as to release the liquid seasonings therein when the liquid seasonings are delivered to the corresponding cooking station. The liquid material barrel 310 comprises: an upper barrel body 311, a lower barrel body 312, a liquid outlet pipe 313, a fixing sleeve 314, a bearing 315, a cam 316, an air pipe, a first valve assembly 318, a second valve assembly 319, an elastic member, a traction rope and an end cover 3191.

[0072] The upper barrel 311 has a cover that can be opened or closed on the top and a liquid outlet on the bottom. The liquid outlet is opened or closed by the first valve assembly 318. The lower barrel 312 is installed at the bottom of the upper barrel 311 and selectively communicates with the upper barrel 311 as the liquid outlet is opened or closed. At the same time, an air pipe is arranged through the upper barrel 311, one end of which extends to the external environment and the other end extends to the lower barrel 312, so as to maintain the balance of air pressure and facilitate the smooth outflow of liquid.

[0073] The first valve assembly 318 includes: a plug cover 3181, a push rod 3182 and a first spring. The plug cover 3181 is sleeved on the upper end of the push rod 3182, and the push rod 3182 is inserted into the liquid outlet of the upper barrel body 311, and its lower end extends into the lower barrel body 312. The above-mentioned first spring is arranged between the lower end of the push rod 3182 and the end surface of the liquid outlet, and the first spring is in a compressed state. In this way, the plug cover 3181 can seal the liquid outlet at the bottom of the upper barrel body 311 through the above-mentioned compression of the first spring. In order to increase the sealing area of ​​the plug cover 3181, the contact surface between the plug cover 3181 and the liquid outlet is an inclined surface.

[0074] The lower barrel 312 has a transversely arranged inner cavity 3121, one end of which is open and the other end is closed. The side wall of the inner cavity 3121 also has an opening 31211. The liquid outlet pipe 313, the bearing 315, the cam 316, and the second valve assembly 319 are integrated in the inner cavity 3121. The liquid outlet pipe 313 is arranged in the inner cavity 3121 along the axial direction, one end of the liquid outlet pipe 313 extends from the inner cavity 3121, and the extended end of the liquid outlet pipe 313 is T-shaped, and the T-shaped pipe head 3131 has one end for liquid discharge and the other end is closed. Such a setting ensures that the residual liquid after the liquid discharge is stored in the closed end of the T-shaped pipe head 3131 to prevent dripping during operation. The opening 31211 at the other end of the liquid outlet pipe 313 is opened or closed by the second valve assembly 319.

[0075] The extended end of the liquid outlet pipe 313 is installed at the open end of the inner cavity 3121 through the fixing sleeve 314. The fixing sleeve 314 includes: a fixing sleeve body 3141 and a clamp 3142 arranged on the outside of the fixing sleeve 314 body. The fixing sleeve 314 is sleeved on the open end of the inner cavity 3121 through its clamp 3142, and can pivot relative to the open end of the inner cavity 3121. The liquid outlet pipe 313 is inserted into the fixing sleeve 314 body. The bearing 315 is sleeved on the liquid outlet pipe 313 to assist the liquid outlet pipe 313 to pivot relative to the inner cavity 3121.

[0076] The cam 316 is sleeved on the liquid outlet pipe 313 and arranged opposite to the opening 31211 on the inner cavity 3121. The lower end of the push rod 3182 of the first valve assembly 318 extends into the opening 31211, and its end face abuts against the cam 316. In this way, when the liquid outlet pipe 313 pivots, the cam 316 thereon pivots synchronously therewith, so that the cam 316 can push the plug cover 3181 open through the push rod 3182, so that it opens with the liquid outlet of the upper barrel body 311 as described above, so that the liquid seasoning stored in the upper barrel body 311 flows into the lower barrel body 312. When the liquid outlet pipe 313 pivots in the opposite direction, the cam 316 returns to the initial position, and the plug cover 3181 closes the liquid outlet at the bottom of the upper barrel body 311 again.

[0077] As described above, the second valve assembly 319 opens or closes the other end of the liquid outlet pipe 313. Specifically, the second valve assembly 319 includes: a first top sleeve 3191, a second top sleeve 3192, a sealing cover 3193 and a second spring 3194. The first top sleeve 3191 is sleeved on the other end of the liquid outlet pipe 313, and the end surface of the first top sleeve 3191 has two convex surfaces arranged symmetrically at the center, and the second top sleeve 3192 has two convex surfaces arranged symmetrically at the center. The first top sleeve 3191 cooperates with the second top sleeve 3192, and the convex surface on the first top sleeve 3191 extends between the convex surfaces on the second top sleeve 3192. A second spring 3194 is also arranged between the second top sleeve 3192 and the closed end of the inner cavity 3121, and the second spring 3194 is in a compressed state. The sealing cover 3193 is accommodated and installed in the second top sleeve 3192, and can seal the opening 31211 at the other end of the above-mentioned liquid outlet pipe 313 under the action of the second spring 3194.

[0078] Thus, when the liquid outlet pipe 313 pivots, the first top sleeve 3191 thereon can pivot synchronously therewith, and at this time, the convex surface on the first top sleeve 3191 can slide along the convex surface on the second top sleeve 3192, thereby pushing the second top sleeve 3192 to move axially, so that the sealing cover 3193 therein is separated from the opening 31211 at the other end of the liquid outlet pipe 313, so that the liquid seasoning flowing into the inner cavity 3121 through the opening 31211 on the inner cavity 3121 can flow into the liquid outlet pipe 313, and further flow out through the liquid outlet of the liquid outlet pipe 313. When the liquid outlet pipe 313 pivots in the opposite direction, the second top sleeve 3192 returns to the initial position, and the sealing cover 3193 closes the opening 31211 at the other end of the liquid outlet pipe 313 again.

[0079] In order to realize the pivoting of the liquid outlet pipe 313, one end of the traction rope is connected to the fixed sleeve 314, so that when a pulling force is applied to the traction rope, the traction rope can further pull the liquid outlet pipe 313 connected to the fixed sleeve 314 to pivot. Thereby, the liquid outlet pipe 313 can drive the first valve assembly 318 and the second valve assembly 319 to open, so as to realize the discharge of liquid seasoning. At the same time, in order to realize the reverse pivoting of the liquid outlet pipe 313, one end of the elastic member is connected to the output end of the liquid outlet pipe 313, and the other end is fixedly connected to the upper barrel body 311. In this way, when the pulling force is stopped on the traction rope, under the action of the reset pulling force of the elastic member, the liquid outlet pipe 313 can pivot in the opposite direction and return to the initial position. In one embodiment, the elastic member is a spring.

[0080] like Figure 5 As shown, the first solid material barrel 320 is used to store small particles or powdered solid seasonings, and includes: a first barrel body 321, a first blowing pipe 322, a first outer gear plate 323, a first stirring mechanism 324, a material dial 325 and a discharging unit 326.

[0081] The first barrel 321 is used to store solid seasonings. A barrel cover 3211 is provided on the top. A material trough is formed around the edges of the bottom. A discharge port is provided on the material trough. A bottom cover 3212 is also fastened to the bottom of the first barrel 321. An opening 31211 is provided on the bottom cover 3212. The opening 31211 is opened or closed by a flap 3213. A feeding port is also provided on the outer wall of the first barrel 321. The feeding port is opened or closed by a material door.

[0082] The first outer gear plate 323 is installed on the top of the barrel cover 3211, and the first outer gear plate 323 is connected to the discharging unit 326 below the first barrel body 321 through an axially penetrating gear shaft 3231. In this way, when the first outer gear plate 323 pivots, it can drive the discharging unit 326 connected thereto to discharge materials.

[0083] The first air blowing pipe 322 is used to blow out the solid seasoning, and it penetrates the gear shaft 3231, and the two ends of the first air blowing pipe 322 extend from the gear shaft 3231. The lower end of the first air blowing pipe 322 can abut against the flap 3213 on the bottom cover 3212. At the same time, an air nozzle 3221 is also installed at the upper end of the first air blowing pipe 322, and a compression spring 3222 is also arranged between the air nozzle 3221 and the first outer gear plate 323. In this way, air can be ventilated into the first air blowing pipe 322 through the above-mentioned air nozzle 3221.

[0084] The first stirring mechanism 324 is used to break up the solid seasoning in the first barrel 321 so that the solid seasoning can be discharged smoothly. The first stirring mechanism 324 includes: a stirring rod 3241 and a plurality of stirring fins 3242 .

[0085] Among them, the stirring rod 3241 is arranged on the outside of the gear shaft 3231 through a frame body 3243. The frame body 3243 includes a circular ring arranged opposite to each other up and down and four connecting rods connecting the two circular rings. There are a plurality of stirring rods 3241, and the plurality of stirring rods 3241 are connected to the circular ring and the connecting rod according to their respective angles, and extend toward the middle stirring shaft. In one embodiment, two central stirring rods 3241 are connected to the upper circular ring, and two connecting rods arranged opposite to each other are respectively connected to a connecting rod, and a stirring rod 3241 inclined downward is respectively provided at the connection between the lower circular ring and the connecting rod.

[0086] Multiple groups of stirring fins 3242 are mounted on the gear shaft 3231 from top to bottom and can be pivoted synchronously with the gear shaft 3231. In one embodiment, the stirring fins 3242 are three groups, wherein the two upper groups of stirring fins 3242 each have three stirring fins, each stirring fin is tilted downward. The stirring fin 3242 of the lowest group has three stirring fins, each stirring fin is tilted upward. Each stirring fin has a cutting edge suitable for cutting into solid seasonings.

[0087] The material-dividing plate 325 is mounted on the lower end of the gear shaft 3231, and includes: a material-dividing plate body 3251 and material-dividing pieces 3252 arranged around the material-dividing plate body 3251. Any material-dividing piece 3252 can move along the material trough at the bottom of the first barrel 321. In this way, when the first outer gear plate 323 drives the gear shaft 3231 to pivot, the material-dividing plate 325 can divert the scattered solid seasoning from the material outlet of the material trough. At the same time, any material-dividing piece 3252 is also provided with a waist-shaped hole.

[0088] The discharging unit 326 includes: an inner gear plate 3261 and a planetary gear 3262. The inner gear plate 3261 is located below the first barrel 321, and has at least one discharge port. The lower end of the gear shaft 3231 is meshed with the inner gear plate 3261 through the planetary gear 3262. In this way, when the first outer gear plate 323 drives the gear shaft 3231 to pivot, there is a speed difference between the material-prying plate 325 and the inner gear plate 3261, so that when the discharge port on the inner gear plate 3261 is aligned with the discharge port of the material trough, the gear shaft 3231 can drive the material-prying plate 325 to push the solid seasoning out of the discharge port and the discharge port. The pushed out solid seasoning falls into the bottom cover 3212 . At this time, when the first air blowing pipe 322 is pressed downward under the action of external force, the flap 3213 can be pushed open, and at the same time, the first air blowing pipe 322 blows air flow to blow out the solid seasoning that falls into the bottom cover 3212 .

[0089] Alternatively, in order to achieve quantitative discharging, in another embodiment, in addition to the first solid material barrel 320 including the similar first barrel body 321 , the first external gear plate 323 , the first stirring mechanism 324 , and the material discharging plate 325 , the discharging unit 326 is improved.

[0090] At this time, if Figure 6As shown, the discharging unit 326 in this embodiment further includes: a transmission gear set 3263, a quantitative discharging tray 3264 and a material chamber 3265. The transmission gear set 3263 and the quantitative discharging tray 3264 are installed in the material chamber 3265, and an opening is provided at the bottom of the first barrel 321 to communicate with the space of the material chamber 3265 where the quantitative discharging tray 3264 is located. The transmission gear set 3263 includes: a first gear 32631 sleeved on the lower end of the gear shaft 3231, a second gear 32632 meshed with the first gear 32631 and pivotally connected to the material chamber 3265, a screw rod 32634 with a third gear 32633 meshed with the second gear 32632 sleeved on one end, and a fourth gear 32635 meshed with the screw rod 32634.

[0091] The quantitative discharging disc 3264 is arranged opposite to the bottom opening of the first barrel 321, and the bottom of the material cavity 3265 is also provided with a drop opening 32651 arranged opposite to the quantitative discharging disc 3264. The quantitative discharging disc 3264 includes: end plates 32641 on both sides, and a paddle 32642 installed between the end plates 32641 on both sides and equally dividing the space between the end plates 32641 on both sides. The fourth gear 32635 is sleeved on the pivot at one end of the quantitative discharging disc 3264. In this way, when the first outer gear disc 323 drives the gear shaft 3231 to pivot, the paddle disc 325 can pivot synchronously, and the solid seasoning in the first barrel 321 is paddled into the material cavity 3265, and fills the space between the two paddles 32642. The transmission gear set 3263 synchronously drives the quantitative discharging tray 3264 . Since the capacities between the paddles 32642 remain consistent, the quantitative discharging tray 3264 discharges the solid seasoning quantitatively through the paddles 32642 thereon.

[0092] Alternatively, in order to adjust the discharge amount of the seasoning, in another embodiment, in addition to the first solid material barrel 320 including a similar first barrel body 321 , a first external gear plate 323 , a first stirring mechanism 324 , and a material switching plate 325 , an improved design of the discharge unit 326 is provided.

[0093] In this embodiment, if Figure 7 As shown, the bottom cover 3212 is screwed to the bottom of the first barrel 321 .

[0094] The discharging unit 326 includes: a spring 3266 , an adjusting plate 3267 , a fixing plate 3268 , a planetary gear 3269 , a material gate 3270 and a material gate cylinder 3271 .

[0095] The fixed disk 3268 is located below the first barrel 321, and has a discharge port. The lower end of the gear shaft 3231 is meshed with the fixed disk 3268 via the planetary gear 3269. The adjustment disk 3267 is arranged below the fixed disk 3268, and the adjustment disk 3267 is provided with a discharge channel 32671 that can extend to the discharge port on the fixed disk 3268 and a guide column 32672 that can be inserted into the fixed disk 3268. The discharge channel 32671 of the adjustment disk 3267 is connected to the material bin of the bottom cover 3212. The spring 3266 is arranged between the adjustment disk 3267 and the fixed disk 3268, and the spring 3266 is in a compressed state. With such arrangement, when the discharge amount needs to be adjusted, the bottom cover 3212 can be rotated to move the bottom cover 3212 away from the fixed disk 3268. At this time, due to the elastic effect of the spring 3266, the adjustment disk 3267 can be closely attached to the bottom cover 3212. Accordingly, the volume between the bins of the bottom cover 3212 is increased, thereby achieving the purpose of adjusting the discharge amount.

[0096] Therefore, when the first outer gear plate 323 drives the gear shaft 3231 to pivot, there is a speed difference between the material-pickup plate 325 and the fixed plate 3268, so that when the discharge port on the fixed plate 3268 is aligned with the discharge port at the bottom of the first barrel, the gear shaft 3231 can drive the material-pickup plate 325 to push the solid seasoning out of the discharge port and the material-pickup port, and enter the silo through the discharge channel 32671. At this time, the material door cylinder 3271 drives the material door 3270 to open the discharge port at the bottom of the silo, so as to realize the quantitative discharge of the solid seasoning.

[0097] The second solid material barrel 330 is used to store large-particle solid seasonings, which can grind the large-particle solid seasonings into small particles or powdered solid seasonings.

[0098] like Figure 8 As shown, the second solid material barrel 330 includes: a second barrel body 331 , a second blowing pipe 332 , a second outer gear plate 333 , a second stirring mechanism 334 and a grinding mechanism 335 .

[0099] The second barrel 331 is used to store large-particle solid seasonings. A barrel cover 3311 is provided on the top and a discharge port is provided at the bottom. The discharge port is opened or closed by a bottom cover 3312. Specifically, the bottom cover 3312 is screwed to the discharge port and has a cover 3313 for opening or closing the discharge port. A feeding port is also provided on the outer wall of the second barrel 331, and the feeding port is opened or closed by a feeding door 3314.

[0100] The second outer gear plate 333 is mounted on the top of the barrel cover 3311, and the second outer gear plate 333 is connected to the grinding mechanism 335 through an axially penetrating gear shaft 336. In this way, when the second outer gear plate 333 pivots, it can drive the grinding mechanism 335 connected thereto to grind.

[0101] The second air blowing pipe 332 is used to blow out the ground solid seasoning, which runs through the gear shaft 336, and the two ends of the second air blowing pipe 332 extend from the gear shaft 336. The lower end of the second air blowing pipe 332 is connected to the cover 3313, so that when the second air blowing pipe 332 is pressed down, the cover 3313 can be driven to move synchronously to open the discharge port closed by it. At the same time, an air nozzle 3321 is also installed at the upper end of the second air blowing pipe 332, and a compression spring 3322 is also arranged between the air nozzle 3321 and the second outer gear plate 333. In this way, air can be ventilated into the second air blowing pipe 332 through the above-mentioned air nozzle 3321. In addition, the surrounding edges of the cover 3313 are set as a slope suitable for closing the discharge port, and a plurality of air outlets are also circumferentially opened on the slope. The plurality of air outlets are respectively connected to the lower end of the second air blowing pipe 332 through the air channel inside the cover 3313.

[0102] The second stirring mechanism 334 is used to break up the solid seasoning in the second barrel 331 so that the solid seasoning can be ground smoothly. The second stirring mechanism 334 includes a stirring rod 3341 and a plurality of stirring fins 3342 .

[0103] Among them, the stirring rod 3341 is arranged on the outside of the gear shaft 336 through a frame body 3343. The frame body 3343 includes a circular ring arranged opposite to each other up and down and four connecting rods connecting the two circular rings. There are a plurality of stirring rods 3341, and the plurality of stirring rods 3341 are connected to the circular ring and the connecting rod according to their respective angles, and extend toward the middle stirring shaft. In one embodiment, two central stirring rods 3341 are connected to the upper circular ring, and two connecting rods arranged opposite to each other are respectively connected to a connecting rod, and a stirring rod 3341 inclined downward is respectively provided at the connection between the lower circular ring and the connecting rod.

[0104] Multiple groups of stirring fins 3342 are mounted on the gear shaft 336 from top to bottom and can be pivoted synchronously with the gear shaft 336. In one embodiment, there are four groups of stirring fins 3342, wherein the upper two groups of stirring fins 3342 each have three stirring fins, each stirring fin is tilted downward. The lower two groups of stirring fins 3342 each have three stirring fins, each stirring wing is tilted upward. The width of the lowermost group of stirring fins is greater than the width of the groups of stirring fins above it. Each stirring wing has a cutting edge suitable for cutting into solid seasonings.

[0105] The grinding mechanism 335 is used to grind large particles of solid seasoning to form small particles or powdered solid seasoning. The grinding mechanism 335 includes: grinding inner teeth 3351 and grinding outer teeth 3352 .

[0106] Among them, the grinding inner teeth 3351 are installed at the lower end of the gear shaft 336. The grinding inner teeth 3351 are roughly in a cone shape, and a plurality of grinding inner teeth 3351 arranged at intervals in the circumferential direction are formed on the conical surface. A feeding trough is formed between the grinding inner teeth 3351. The edges on both sides of any grinding inner teeth 3351 form a first main grinding edge 33511, and the edges around one end of the grinding inner teeth 3351 are also formed with circumferentially arranged first secondary grinding edges 33512. The above-mentioned first main grinding edges 33511 and first secondary grinding edges 33512 are arranged obliquely according to the pivot direction. The grinding outer teeth 3352 are arranged in the above-mentioned bottom cover 3312. Correspondingly, the grinding outer teeth 3352 have second main and secondary grinding edges 33521 and 33522 corresponding to the first main and secondary grinding edges on the grinding inner teeth 3351.

[0107] When the second outer gear plate 333 drives the gear shaft 336 to pivot, the second stirring mechanism 334 breaks up the solid seasoning in the second barrel 331, and the broken up solid seasoning can fall into the grinding mechanism 335 below. At this time, the grinding inner teeth 3351 of the grinding mechanism 335 can pivot with the gear shaft 336, so that the solid seasoning entering between the grinding inner teeth 3351 and the grinding outer teeth 3352 is ground into small particles or powdered solid seasoning. At the same time, the second blowing pipe 332 synchronously opens the cover 3313, and the small particles or powdered solid seasoning is blown out by the airflow.

[0108] In addition, according to actual needs, a barrel for storing viscous substances and / or sauces may also be provided.

[0109] like Fig. 9 , 10 As shown, the feeding mechanism 35 is used to control the first feeding device 30 to feed when the material barrel in the first feeding device 30 moves to the feeding position. The fed seasonings include: a number of liquid seasonings, solid (granular, powder, block, diced, etc.) seasonings, viscous seasonings, sauces, and moist granular (such as ginger) seasonings.

[0110] The unloading mechanism 35 includes a liquid unloading unit 351 and a solid unloading unit 352 .

[0111] The liquid unloading unit 351 includes a push plate 3511 , a connecting frame 3512 , a fixing plate 3513 and a first pivoting motor 3514 .

[0112] Among them, the first pivot motor 3514 is fixed on the base 36, and is connected to one end of the first screw rod 3516 through a transmission belt 3515. The lower end of the connecting frame 3512 is connected to the first screw rod 3516, and the upper end of the connecting frame 3512 is connected to the fixed plate 3513, so that when the first pivot motor 3514 is working, it can drive the fixed plate 3513 to reciprocate through the connecting frame 3512. In other embodiments, the first pivot motor 3514 and the first screw rod 3516 can also be replaced by a cylinder. One end of the push plate 3511 is connected to the fixed plate 3513 and can move synchronously with the fixed plate 3513. The other end of the push plate 3511 is connected to or integrally provided with a curved top plate 35111.

[0113] Thus, when the liquid barrel 310 moves to the unloading position under the drive of the cyclic pivoting power mechanism 33, the first pivoting motor 3514 can drive the push plate 3511 on the fixed plate 3513 to move toward the liquid barrel 310, so that the arc top plate 35111 on the push plate 3511 interacts with the traction rope of the liquid barrel 310, and the traction rope further pulls the liquid outlet pipe 313 connected to the fixed sleeve 314 to pivot. The liquid outlet pipe 313 can drive the first valve assembly 318 and the second valve assembly 319 to open, so as to realize the discharge of liquid seasoning.

[0114] The solid material discharge unit 352 includes: a transmission gear 3521 , a second pivot motor 3522 , a buffer structure 3523 and an air supply structure 3524 .

[0115] The transmission gear 3521 is used to mesh with the outer gear discs 323 and 333 of the first solid material barrel 320 or the second solid material barrel 330, thereby driving the outer gear discs 323 and 333 to pivot, so as to discharge the first solid material barrel 320 or the second solid material barrel 330. The transmission gear 3521 is connected between the fixed plate 3513 and the push plate 3511 through a pivot shaft 35211, and a pulley 35212 is coaxially arranged on the transmission gear 3521, and the second pivot motor 3522 is linked with the pulley 35212 of the transmission gear 3521 through a transmission belt. In this way, when the second pivot motor 3522 is working, the transmission gear 3521 can be driven to pivot synchronously through the transmission belt and the pulley 35212.

[0116] When the first pivot motor 3514 is working, it can also drive the transmission gear 3521 to move toward the outer gear disk 323, 333 of the first solid material barrel 320 or the second solid material barrel 330, so that the transmission gear 3521 is meshed with the corresponding outer gear disk 323, 333. At the same time, in order to facilitate the transmission gear 3521 to smoothly mesh with the outer gear disk 323, 333, the transmission gear 3521 adopts a missing tooth design. Specifically, when the transmission gear 3521 is in the initial position, the meshing teeth on the side facing the outer gear disk 323, 333 are not continuously arranged, that is, there is no meshing tooth between the two meshing teeth arranged at intervals, which is conducive to avoiding the end face of the meshing teeth of the transmission gear 3521 from abutting against the end face of the meshing teeth of the outer gear disk 323, 333 during the meshing process between the transmission gear 3521 and the outer gear disk 323, 333. In addition, the meshing teeth on both sides of the missing tooth position have a length difference, that is, one meshing tooth 35213 is longer and the other meshing tooth 35214 is shorter. This is beneficial for the transmission gear 3521 to smoothly drive the outer gear plates 323 and 333 to pivot after meshing to avoid interference.

[0117] The buffer structure 3523 is used to provide a buffering force when the transmission gear 3521 is meshed with the outer gear plate 323, 333. And the buffer structure 3523 can also provide a fine-tuning force when the transmission gear 3521 is not fully meshed with the outer gear plates 323, 333 so that the two are well matched together. Specifically, the buffer structure 3523 includes: a baffle 35231, a spring 35232 and a baffle 35233. Among them, the baffle 35231 is a U-shaped structure, and its two ends are respectively connected to the two ends of the pivot of the transmission gear 3521. The baffle 35233 is located on one side of the baffle 35231 and is fixed on the push plate 3511. The spring 35232 is arranged between the baffle 35231 and the baffle 35233 and is in a compressed state. In this way, the spring 35232 provides a force for the transmission gear 3521 to achieve the above-mentioned buffering and fine-tuning effects.

[0118] like Fig.11 As shown, the air supply structure 3524 is used to provide a blowing air flow for the above-mentioned air pipe, the first blowing air pipe 322 and the second blowing air pipe 332 .

[0119] Specifically, the air supply structure 3524 includes: an air supply pipe 35241 and a swing assembly 35242. The air supply pipe 35241 is a rigid air pipe, and an air outlet nozzle arranged downward is arranged at its end. The swing assembly 35242 includes: a guide plate 352421 and a pivot mounting seat 352422, and the air supply pipe 35241 is pivotally mounted on the vertical plate 3342 through the pivot mounting seat 352422. The pivot mounting seat 352422 includes: a fixed seat 3524221 and a pivot connection sleeve 3524222. The fixed seat 3524221 is installed on the vertical plate 3342 and is located on one side of the push plate 3511. One end of the pivot connection sleeve 3524222 is sleeved on the air supply pipe 35241, and the other end is pivotally connected to the fixed seat 3524221 through a pin shaft. The guide plate 352421 is fixed to one side of the push plate 3511 and can move synchronously with the movement of the push plate 3511 .

[0120] The guide plate 352421 is provided with a guide groove 3524211 which is inclined downward toward the material discharge position. Meanwhile, the air supply pipe 35241 is also provided with another pivot connection sleeve 3524222. A pin is inserted between one end of the pivot connection sleeve 3524222 and the guide groove, and the pin is initially located at one end of the guide groove near the material discharge position. The other pivot connection sleeve 3524222 is located behind the pivot mounting seat 352422.

[0121] With such a configuration, when the push plate 3511 moves toward the material unloading position, the pin of the air supply pipe 35241 can move from the lower end to the higher end along the guide groove. Accordingly, the guide plate 352421 can press the air outlet of the air supply pipe 35241 downward to communicate with the air pipe, the first air blowing pipe 322 or the air inlet of the second air blowing pipe 332 located at the material unloading position. When the push plate 3511 returns to the initial position, the air supply pipe 35241 can be gradually lifted up and separated from the air pipe, the first air blowing pipe 322 or the air inlet of the second air blowing pipe 332 under the guidance of the guide plate 352421, and the air supply of the air supply pipe 35241 is stopped.

[0122] Again Fig.10 As shown, the positioning mechanism 34 is used to correct the position of each seasoning barrel 31 when it moves to the unloading position, so that the unloading mechanism 35 can drive the corresponding barrel to unload. The positioning mechanism 34 is arranged on the base 36 where the first feeding device 30 is located, and is located on the inner side of the barrel fixing seat 32.

[0123] The positioning mechanism 34 includes a positioning rod 341, which is horizontally arranged, one end of which points to the inner side of the barrel fixing seat 32, and the other end is connected to the connecting frame 3512, so that the positioning rod 341 can move toward or away from the barrel fixing seat 32 with the reciprocating motion of the connecting frame 3512. Correspondingly, a plurality of positioning holes arranged at intervals in the circumferential direction are provided on the inner side of the barrel fixing seat 32, and each positioning hole is arranged opposite to the barrel. In this way, one end of the positioning rod 341 can be inserted into the corresponding positioning hole with the movement of the connecting frame 3512 to calibrate and position the corresponding barrel, so that the unloading mechanism 35 can drive the corresponding barrel to unload. In addition, in order to prevent the positioning rod 341 from shaking during the movement, the positioning mechanism 34 also includes a guide arm 342. The positioning rod 341 is also inserted into the guide hole of the guide arm 342 and can move axially along the guide hole. At the same time, the other end of the first screw rod 3516 which is transmission-connected to the first pivot motor 3514 is pivotally connected to the bottom of the guide arm 342 .

[0124] The seasoning barrel 31 , the barrel fixing seat 32 and the material discharge mechanism 35 are accommodated in a protection cover 37 , and the protection cover 37 provides protection for the seasoning barrel 31 , the barrel fixing seat 32 and the material discharge mechanism 35 therein.

[0125] like Figure 1 As shown, the second feeding device 40 is used to supply consumables with large amount of cooking oil, etc., and it works synchronously or asynchronously with the first feeding device 30. The second feeding device 40 includes a plurality of feeding units 41, and any feeding unit 41 includes: a storage barrel 42 and a pressure storage cylinder 43.

[0126] The storage barrel 42 is connected to the pressure storage barrel 43 through a pipeline. The storage barrel 42 is used to store consumables with a large amount of consumption such as cooking oil. The storage barrel 42 is a hollow barrel body with an interface for pipe connection on the top, which is connected to the inside of the barrel body.

[0127] like Fig.12 As shown, the pressure storage barrel 43 is capable of receiving large-volume consumables such as edible oil from the storage barrel 42, and is used to maintain a quantitative and stable outflow of edible oil under a constant pressure. The pressure storage barrel 43 includes: a barrel body 431, a barrel seat 432, a barrel cover 433, a barrel cover locking hoop 434, a regulating valve 435, a split stop valve 436, an extrusion discharge barrel 437 and a discharge mechanism 438.

[0128] Among them, the cylinder 431 is fixed to the upper layer of the material rack 46 through the cylinder seat 432. The cylinder cover 433 is used to open or close the cylinder 431, which is buckled on the top of the cylinder 431 and locked by the cylinder cover locking hoop 434, and a pipeline interface 4331 is provided on the cylinder cover 433. Considering that the pressure in the cylinder 431 will change with the continuous outflow of edible oil, etc., the cylinder cover 433 is also provided with an external air source interface 4332 and a pressure gauge 4333. In this way, when edible oil, etc. continues to flow out, pressurized gas can be introduced through the external air source interface to compensate for the internal pressure so that the pressure inside the cylinder 431 remains constant. The cylinder cover locking hoop 434 can adopt an existing locking hoop, which has two locking arms pivotally connected at the ends, and the two locking arms can be locked and connected by a latch.

[0129] The bottom of the cylinder is also connected to an outflow pipe, and the regulating valve 435, the split stop valve 436, the extrusion discharge cylinder 437 and the discharge mechanism 438 are installed on the outflow pipe in sequence.

[0130] like Fig.13 As shown, the regulating valve 435 includes: a regulating valve body 4351, a regulating valve stem 4352, a handle 4353 and a regulating tooth plate 4354. The regulating valve body 4351 is vertically and horizontally connected inside, and the regulating valve body 4351 has a pipeline interface connected to the internal transverse pipeline. The regulating valve body 4351 is connected to the outflow pipeline through the pipeline interfaces at both ends, and the pipeline interface and the outflow pipeline are locked by a clamp 4355. The regulating valve stem 4352 is pivotally inserted into the longitudinal pipeline inside the regulating valve body 4351, and the regulating valve stem 4352 is also provided with a valve plate 43521, which is located at the intersection of the longitudinal and transverse pipelines inside the regulating valve body 4351. In this way, when the regulating valve stem 4352 is pivoted, the valve plate on it can realize the adjustment of the opening at the intersection of the longitudinal and transverse pipelines inside the regulating valve body 4351, thereby changing the flow inside the outflow pipeline.

[0131] One end of the handle 4353 is connected to the upper end of the regulating valve stem 4352, and can drive the regulating valve stem 4352 to pivot. At the same time, the end of the handle 4353 connected to the regulating valve stem 4352 is also provided with a latching tooth 43531. The regulating tooth plate 4354 is installed on the end of the handle 4353 connected to the regulating valve stem 4352, and the regulating tooth plate 4354 is provided with circumferentially spaced slots that can cooperate with the latching teeth. In this way, when the handle 4353 drives the regulating valve stem 4352 to pivot to the required angle, the latching tooth 43531 thereon can cooperate with the latching groove at the corresponding angle, so that the position of the regulating valve stem 4352 remains fixed to prevent it from pivoting freely.

[0132] like Fig.14As shown, the split stop valve 436 is used to control the switch of the outflow pipeline, which includes: a split stop valve body 4361, a split stop valve stem 4362 and a valve body cylinder 4363. The split stop valve body 4361 is arranged to be vertically and horizontally connected inside, and the split stop valve body 4361 has two pipeline interfaces connected to the internal transverse pipeline. The split stop valve body 4361 is connected to the outflow pipeline through the two pipeline interfaces, and the pipeline interface and the outflow pipeline are locked by a clamp. In another embodiment, the two pipeline interfaces on the split stop valve body 4361 remain vertical. The split stop valve stem 4362 is inserted into the longitudinal pipeline inside the split stop valve body 4361, and the split stop valve stem 4362 is connected to the valve body cylinder 4363, and can be driven by the valve body cylinder 4363 to perform telescopic movement to open or close the outflow pipeline.

[0133] In order to facilitate the installation and fixation of the valve body cylinder 4363, the valve body cylinder 4363 is installed on the upper end surface of the split stop valve body 4361 through the first column 4365, and a gasket 4366 is also provided between the first column 4365 and the upper end surface of the split stop valve body 4361. In one embodiment, the valve body cylinder 4363 is installed and fixed through two first columns 4365, and the split stop valve rod 4362 is located between the two first columns 4365. In addition, in order to facilitate the maintenance of the inside of the split stop valve body 4361, the split stop valve body 4361 is also provided with an inspection port connected to the internal transverse pipeline, and an inspection cover is screwed on the inspection port.

[0134] like Fig.15 As shown, the extrusion discharge barrel 437 is used to achieve controllable and precise metering discharge, which includes: a measuring barrel body 4371, a piston 4372, a screw stepping motor 4373, a lower cover 4374, a feed pipe 4375 and a discharge pipe 4376.

[0135] The measuring cylinder body 4371 is hollow inside, and the piston 4372 is located in the measuring cylinder body 4371. The edges of the piston 4372 are in contact with the inner wall of the measuring cylinder body 4371, and a sealing ring is provided between the edges of the piston 4372 and the inner wall of the measuring cylinder body 4371. As required, more than one O-ring can be mounted on the piston 4372. The screw stepper motor 4373 is installed on the top of the measuring cylinder body 4371, and its screw 43731 extends into the measuring cylinder body 4371 and is connected to the piston 4372, thereby driving the piston 4372 to perform axial reciprocating motion in the measuring cylinder body 4371.

[0136] The lower cover 4374 is screwed to the opening at the bottom of the measuring cylinder body 4371 to close the bottom opening of the measuring cylinder body 4371. The feed pipe 4375 and the discharge pipe 4376 are connected to the lower cover 4374 and are connected to the inside of the measuring cylinder body 4371. The feed pipe 4375 and the discharge pipe 4376 are further connected to the outflow pipe where they are located, so that edible oil and the like can enter the measuring cylinder body 4371 through the feed pipe 4375 and can flow out through the discharge pipe 4376. At the same time, the connection between the feed pipe 4375 and the discharge pipe 4376 and the outflow pipe is locked by a clamp. Since the screw stepper motor 4373 can control its screw 43731 to pivot according to a set angle, it can push the piston 4372 connected thereto to move according to a set stroke. In this way, the screw stepper motor 4373 can accurately drive the piston 4372 to squeeze the edible oil or the like in the measuring cylinder body 4371 , thereby achieving the purpose of controlling the precise discharge of the extrusion discharge cylinder 437 .

[0137] Again Fig.15 As shown, the discharge mechanism 438 forms an outlet of the discharge pipe, which includes: a discharge stop valve body 4381 , a discharge stop valve stem 4382 , a discharge cylinder 4383 and a discharge nozzle 4384 .

[0138] The discharge stop valve body 4381 is arranged to be vertically and horizontally connected inside, and the discharge stop valve body 4381 has a pipeline interface connected to the internal horizontal pipeline. The discharge stop valve body 4381 is connected to the tail end of the outflow pipeline through its pipeline interface, and the pipeline interface and the outflow pipeline are locked by a clamp. The discharge stop valve stem 4382 is inserted into the longitudinal pipeline inside the discharge stop valve body 4381, and the discharge stop valve stem 4382 is connected to the discharge cylinder 4383, and can be driven by the discharge cylinder 4383 to perform telescopic movement to open or close the outflow pipeline. In order to facilitate the installation and fixation of the discharge cylinder 4383, the discharge cylinder 4383 is installed on the upper end surface of the discharge stop valve body 4381 through the second column, and a gasket is also arranged between the second column and the upper end surface of the discharge stop valve body 4381. In one embodiment, the discharge cylinder 4383 is installed and fixed by two columns, and the discharge stop valve stem 4382 is located between the two columns.

[0139] The discharge nozzle 4384 is connected to the opening at the bottom of the discharge stop valve body 4381, and the opening is connected to the longitudinal pipeline inside the discharge stop valve body 4381. One end of the discharge nozzle 4384 can be connected to the bottom of the discharge stop valve body 4381 by screw connection, and the other end is formed with a nozzle opening.

[0140] In one embodiment, if Fig.16 As shown, the discharge nozzle 4384 includes: a connecting sleeve 43841 and a discharge nozzle body 43842 .

[0141] The connecting sleeve 43841 is provided with an axis through it, and one end of the connecting sleeve 438411 is formed to be screwed to the bottom opening of the discharge stop valve body 4381. The discharge nozzle body 43842 is inserted into the connecting sleeve 43841, and the outer edge of the upper end thereof abuts against the step surface of the threaded sleeve 438411 to achieve axial limitation. At the same time, the lower end of the discharge nozzle body 43842 forms a nozzle opening 438421 and extends out from the connecting sleeve 43841.

[0142] In order to prevent the discharge nozzle 4384 from dripping, the material of the discharge nozzle body 43842 can be silicone material, and the inner diameter and outer diameter of the nozzle opening 438421 gradually decrease along the discharge direction. In this way, when the nozzle opening 438421 is unfolded, due to its own elastic recovery force, it can achieve automatic closure after discharging, so as to prevent the discharge nozzle 4384 from dripping. At the same time, in order to facilitate the opening of the nozzle opening 438421 under a certain pressure, the hardness of the upper part of the discharge nozzle body 43842 is greater than the hardness of the lower part. In this way, when discharging, the lower nozzle opening 438421 opens radially, and when the discharged consumables are all squeezed out, the nozzle opening 438421 can be closed accordingly, so as to achieve the purpose of preventing the discharge nozzle 4384 from dripping. In one embodiment, the nozzle opening 438421 is designed as a conical structure that can be opened.

[0143] According to the different types of consumables fed by the second feeding device 40, the discharge nozzle 4384 can be set to different structural forms.

[0144] For example, when the second feeding device 40 feeds small-particle sauce, Fig.17 As shown, the discharge nozzle 4384 includes: a connecting screw sleeve 43841 and a discharge nozzle body 43842. Among them, the connecting screw sleeve 43841 is mounted on the upper end of the discharge nozzle body 43842, and the material of the connecting screw sleeve 43841 can be stainless steel. The discharge nozzle body 43842 is connected to the bottom of the discharge stop valve body 4381 through the connecting screw sleeve 43841 at its upper end. A nozzle opening 438421 is formed at the lower end of the discharge nozzle body 43842, and the material of the discharge nozzle body 43842 can be silicone material, and the inner diameter and outer diameter of the nozzle opening 438421 are gradually reduced along the discharge direction. In this way, when the nozzle opening 438421 is unfolded, due to its own elastic recovery force, it can be automatically closed after discharging, so as to avoid dripping of the discharge nozzle 4384.

[0145] In one embodiment, the inner side wall of the nozzle opening 438421 includes: a first inner side surface inclined toward the center, a second inner side surface connected to the first inner side surface and extending axially, a third inner side surface connected to the second inner side surface and inclined toward the center, and a fourth inner side surface connected to the third inner side surface and extending in a radial direction to close the nozzle opening 438421.

[0146] The outer wall of the nozzle opening 438421 has a similar structural design to the inner wall of the nozzle opening 438421, which includes: a first outer side surface inclined toward the center, a second outer side surface connected to the first outer side surface and extending axially, a third outer side surface connected to the second outer side surface and inclined toward the center, and an end surface connected to the third outer side surface and extending in the radial direction to close the nozzle opening 438421.

[0147] In addition, in order to further ensure that the nozzle opening 438421 can be automatically closed, the discharge nozzle 4384 also includes a spring clip 43843, which is clamped on the outer side wall opposite to the discharge nozzle 4384. Correspondingly, the outer side wall opposite to the discharge nozzle 4384 is provided with a hole suitable for the spring clip 43843 to pass through. In this way, under the action of the spring clip 43843 and its own elastic recovery, automatic closure after discharging can be achieved.

[0148] For another example, when the second feeding device 40 feeds a liquid or a viscous substance, Fig.18 As shown, the discharge nozzle 4384 includes: a connecting screw sleeve 43841 and a discharge nozzle body 43842. The connecting screw sleeve 43841 is sleeved on the upper end of the discharge nozzle body 43842, and the material of the connecting screw sleeve 43841 can be stainless steel. The discharge nozzle body 43842 is connected to the bottom of the discharge stop valve body 4381 through the connecting screw sleeve 43841 at its upper end. The discharge nozzle body 43842 can be an axially through-set pipeline, which can be integrally formed with the connecting screw sleeve 43841.

[0149] At this time, in order to avoid the problem of dripping, the discharge nozzle 4384 can be deformed. Specifically, the discharge nozzle 4384 includes: a connecting screw sleeve 43841 and a discharge nozzle body 43842. Among them, the connecting screw sleeve 43841 is mounted on the upper end of the discharge nozzle body 43842, and the material of the connecting screw sleeve 43841 can be stainless steel. The discharge nozzle body 43842 is connected to the bottom of the discharge stop valve body 4381 through the connecting screw sleeve 43841 at its upper end. The discharge nozzle body 43842 includes: a first straight pipe section, an S-shaped bend pipe section and a second straight pipe section connected in sequence. In this way, after the discharge is completed, the S-shaped bend pipe section can prevent the liquid or viscous body in the first straight pipe section from flowing into the second straight pipe section, thereby achieving the purpose of preventing the discharge nozzle 4384 from dripping.

[0150] For example, Fig.19As shown, when the second feeding device 40 feeds large-particle sauce, the discharge nozzle 4384 is axially through-set, with a thread formed on the inner side surface of the upper end and a nozzle opening formed on the lower end. The discharge nozzle 4384 can be connected to the bottom of the discharge stop valve body 4381 through the thread at its upper end. In addition, in order to avoid blockage when discharging large-particle sauce, the discharge nozzle 4384 has a cavity 43841 connected to the nozzle opening at the lower end. At this time, the cavity 43841 is a spherical cavity formed at the lower end of the discharge nozzle 4384, and the nozzle opening is opened at the bottom of the above-mentioned spherical cavity.

[0151] Alternatively, in another embodiment of the feeding unit 41, as Fig. 20 As shown, the pressure storage barrel 43 may only include: a barrel 431, a barrel seat 432, a barrel cover 433, a barrel cover locking hoop 434, a regulating valve 435 and a discharging mechanism 438. At this time, the arrangement of the barrel 431, the barrel seat 432, the barrel cover 433, and the barrel cover locking hoop 434 is the same as that in the previous embodiment, and the discharging mechanism 438 is directly connected to the regulating valve 435, and the edible oil and other consumables from the storage barrel 42 are discharged in sequence through the barrel 431, the regulating valve 435 and the discharging mechanism 438. Therefore, the second feeding device 40 may include the feeding unit 41 of one of the above embodiments, or may include the feeding unit 41 of another of the above embodiments, or may include a combination of the feeding units 41 of the above two embodiments.

[0152] As described above, the second feeding device 40 includes a plurality of feeding units 41. Thus, according to actual needs, the required number of feeding units 41 can be set. In one embodiment, the second feeding device 40 includes six groups of feeding units 41. Among them, the storage barrels 42 of the six groups of feeding units 41 are placed side by side on the lower layer of the material rack, and the pressure storage barrels 43 of the six groups of feeding units 41 are correspondingly placed on the upper layer of the material rack.

[0153] The metering device 60 can realize quantitative weighing. It can pivot along with the secondary rotating arm in the horizontal plane, and then receive seasonings etc. from the first feeding device 30 and / or the second feeding device 40 through the pivoting movement, and deliver the received seasonings etc. to the corresponding cooking station.

[0154] like Fig.21 As shown, the metering device 60 includes: a feeding spoon 61 , a displacement mechanism 62 , a pivot mechanism 63 , a balancing mechanism 64 , an upper base plate 65 , a lower base plate 66 , a reset mechanism 67 and a limit mechanism 68 .

[0155] The middle position of the bottom of the upper base plate 65 is pivotally connected to the lower base plate 66, and the two ends of the upper base plate 65 can swing up and down with the pivot axis in the middle of the bottom as a fulcrum. Specifically, a pivot connection foot is provided at the middle position of the bottom of the upper base plate 65, and a corresponding pivot connection frame is provided on the lower base plate 66, and the pivot connection foot is connected to the pivot connection frames on both sides through the above-mentioned pivot axis.

[0156] like Fig. 22 As shown, the feeding spoon 61 includes: a spoon body and a spoon handle connected to the spoon body at one end. The feeding spoon 61 receives seasonings and the like from the first feeding device 30 and / or the second feeding device 40 through its spoon body. The tail end of the spoon handle is detachably connected to the replacement mechanism 62 and is transmission-connected to the pivot mechanism 63, and is then driven by the pivot mechanism 63 to pivot 180°, so that the seasonings and the like in the spoon body can be fed into the pot at the cooking station.

[0157] The replacement mechanism 62 is used to fix the feeding spoon 61 and facilitate the replacement of the feeding spoon 61. The replacement mechanism 62 is fixed to one side of the middle pivot axis of the upper base plate 65, and includes: a replacement seat 621, a limit rod 622, a limit screw 623 and a spring 624.

[0158] The displacement seat 621 has a hole suitable for the end of the spoon handle to be inserted and installed, and the limiting rod 622 is located in the displacement seat 621 and can abut against the spoon handle inserted in the displacement seat 621 to prevent the feeding spoon 61 from falling out of the displacement seat 621. Correspondingly, the portion of the spoon handle located in the displacement seat 621 also has a groove 611 that matches the limiting rod 622. The limiting rod 622 is arranged horizontally in the displacement seat 621 and has a vertical range of motion, and the limiting rod 622 is arranged horizontally and crosswise with the spoon handle. In one embodiment, the groove 611 is formed on the spoon handle. Two annular grooves 611 are arranged side by side, and the limiting rod 622 is arranged vertically and crosswise with the spoon handle and is inserted into the corresponding groove 611.

[0159] In order to enable the limiting rod 622 to continuously press the corresponding groove 611, the spring 624 is located in the replacement seat 621, one end of which can abut the corresponding limiting rod 622, and the other end is limited by the limiting screw 623 screwed in the replacement seat 621. Correspondingly, the limiting screw 623 is screwed in the spring 624 cavity where the spring 624 is located or at the opening of the spring 624 cavity. In this way, when the feeding spoon 61 needs to be replaced, the feeding spoon 61 can be pulled out in the opposite direction to separate it from the replacement seat 621. When a new feeding spoon 61 needs to be installed, since the limiting rod 622 is arranged horizontally and has a vertical movable amount, the new feeding spoon 61 can be inserted into the hole of the replacement seat 621 according to the installation direction. During the insertion process, the corresponding limiting rod 622 can be pushed away. As the feeding spoon 61 is inserted, the limiting rod 622 abuts against the groove 611, and the feeding spoon 61 is assembled in place.

[0160] The pivot mechanism 63 is used to drive the feeding spoon 61 to pivot so as to put the seasoning and the like in the feeding spoon 61 into the pot at the cooking station. The pivot mechanism 63 is located behind the displacement seat 621 and on one side of the pivot axis in the middle of the upper base plate 65. The pivot mechanism 63 includes a rotary cylinder. The output end of the rotary cylinder has a groove that can match the tail end of the feeding spoon 61. In one embodiment, the groove is a hexagonal groove, and the hexagonal protrusion at the tail end of the feeding spoon 61 can be assembled in the corresponding groove. With such a configuration, when the rotary cylinder is working, it can drive the feeding spoon 61 to pivot at the same part.

[0161] The balancing mechanism 64 realizes the quantitative weighing function of the metering device 60 based on the lever principle, and includes: a balancing block 641, a slide 642, a baffle 643, a second screw 644 and a screw motor 645. The balancing block 641 can be driven by the second screw 644 and the screw motor 645 to reciprocate on the other side of the middle pivot axis of the upper base plate 65. In this way, the balancing block 641 can maintain balance with the screw motor 645 at one end of the upper base plate 65, the displacement mechanism 62, the balancing mechanism 64, the feeding spoon 61 and the seasoning in the feeding spoon 61 by moving to a specific position. Since the weight of the screw motor 645, the displacement mechanism 62, the balancing mechanism 64 and the feeding spoon 61 is constant, the weight of the seasoning in the feeding spoon 61 can be weighed.

[0162] Specifically, the screw motor 645 is located on the other side of the middle pivot axis of the upper base plate 65, and is transmission-connected with one end of the second screw 644. The second screw 644 penetrates the balancing block 641 and is threadedly matched with it. The balancing block 641 is slidably arranged on the slideway 642 below the second screw 644. Then, when the screw motor 645 is working, the second screw 644 can drive the balancing block 641 to reciprocate along the slideway 642. The baffle 643 is installed above the slideway 642, and the balancing block 641 is accommodated between the baffle 643 and the slideway 642 to limit the reciprocating motion of the balancing block 641. By adopting a high-precision servo motor as the screw motor 645, the displacement of the balancing block 641 can be controlled, so that the weight of the seasoning in the corresponding feeding spoon 61 can be weighed according to the displacement value of the balancing block 641.

[0163] The balancing mechanism 64 also plays an oscillating role, so as to throw out the seasoning in the feeding spoon 61. Accordingly, the reset mechanism 67 is located at the end position between the upper base plate 65 and the lower base plate 66 to provide a buffering force for the swing of the upper base plate 65, thereby preventing the upper base plate 65 from swinging irregularly. In one embodiment, the reset mechanism 67 is a spring 624 disposed at the two end positions between the upper base plate 65 and the lower base plate 66.

[0164] In order to make the upper substrate 65 reciprocate within a certain angle range, the limiting mechanism 68 is located at the end position between the upper substrate 65 and the lower substrate 66. In one embodiment, the limiting mechanism 68 is a limiting column arranged at a corresponding position. At this time, the lower end of the limiting column is fixed to the lower substrate 66 by screw locking, and the upper end thereof is at a certain distance from the upper substrate 65 located at the initial equilibrium position.

[0165] like Fig.23 As shown, the water replenishing device 50 is used to provide cold water and / or hot water required for cooking. The water replenishing device 50 is integrated at the bottom of the secondary rotating arm, and includes: a cold water supply mechanism 51, a hot water supply mechanism 52, a water purification mechanism, a first outer cover 53 and a second outer cover.

[0166] The cold water supply mechanism 51 and the hot water supply mechanism 52 are arranged below the bottom plate of the frame, and both are accommodated in the first outer cover 53. The cold water supply mechanism 51 includes: a cold water pipe 511 and a first valve 512 arranged on the cold water pipe 511. One end of the cold water pipe 511 extends from the first outer cover 53 and extends to the material discharge position, and the other end is connected to the cold water outlet of the water purification mechanism. The first valve 512 opens or closes the cold water pipe 511. In one embodiment, the first valve 512 can be a solenoid valve. The hot water supply mechanism 52 includes: a hot water pipe 521 and a second valve 522 arranged on the hot water pipe 521. One end of the hot water pipe 521 extends from the first outer cover 53 and extends to the material discharge position, and the other end is connected to the hot water outlet of the water purification mechanism. The second valve 522 opens or closes the hot water pipe 521. In one embodiment, the second valve 522 can be a solenoid valve. The water purification mechanism can be installed on the machine base and accommodated in the second outer cover. The water purification mechanism comprises a plurality of filters which are connected in parallel and / or in series, and the filters assembled together form a whole having a cold water inlet, a hot water inlet, a cold water outlet and a hot water outlet.

[0167] In summary, the metering feeder of the present invention can automatically provide seasonings for each cooking position. By setting the first feeding device and the second feeding device, it can realize the supply of different types of consumables such as seasonings and edible oils, fully meet the actual cooking needs, and facilitate the realization of cooking automation. At the same time, the metering device can realize the quantitative weighing and discharging of seasonings based on the lever principle, and realize the quantitative supply of consumables such as edible oils.
