The other end of the second-stage rotating arm 24 is connected to the base 36 where the precise feeding machine 30 is located.

[0097] As Figure 2 、 3 shown, the precise feeding machine 30 is used to store the seasonings to be dispensed and dispense the required seasonings when moving to the dispensing position. The precise feeding machine 30 includes: a seasoning barrel 31, a barrel fixing seat 32, a circulating pivoting power mechanism 33, a positioning mechanism 34, and a dispensing mechanism 35.

[0098] The circulating pivoting power mechanism 33 is used to drive each seasoning barrel 31 to perform a circulating rotation movement.

[0099] Specifically, the circulating pivoting power mechanism 33 includes: a circulating pivoting motor 331, an annular rack 332, and a ball clamping structure 333. The circulating pivoting motor 331 is vertically arranged and installed on the base 36 through a motor fixing frame 334. A driving gear 335 is installed at the output end of the circulating pivoting motor 331. The driving gear 335 is horizontally arranged and can pivot synchronously with the operation of the circulating pivoting motor 331.

[0100] 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 provided at the top of the U-shaped fixing frame body 3341, and a support 3343 provided at the bottom of the U-shaped fixing frame body 3341. The U-shaped fixing frame body 3341 is horizontally arranged. The circulating pivoting motor is installed on the top of the U-shaped fixing frame body 3341, and the driving gear 335 is housed in the space surrounded by the U-shaped fixing frame body 3341.

[0101] The annular rack 332 is located on the periphery of the circulating pivot motor 331. A number of continuously arranged meshing teeth are formed on the surface facing the circulating pivot motor 331. The driving gear 335 can mesh with the annular rack 332. In this way, when the circulating pivot motor 331 works, it can drive the annular rack 332 to pivot synchronously. In one embodiment, the annular rack 332 is locked and fixed to the inner side surface of the bucket fixing seat 32 by a number of pins 3321.

[0102] 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 bearing platform 3332. There are a number of upper clamping arms 3331, and each upper clamping arm 3331 is circumferentially spaced inside 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 at the upper end, and the upper ball can slide relatively along the chute on the upper surface of the annular rack 332. The lower bearing platform 3332 is correspondingly arranged in a ring shape, fixed to the base 36, and located below the annular rack 332. A number of lower balls are circumferentially spaced on the top surface of the lower bearing platform 3332, and each lower ball can slide relatively along the chute on the lower surface of the annular rack 332. With such a setting, under the clamping and guiding of a number of upper balls and lower balls, the annular rack 332 can maintain a stable pivoting motion within a certain horizontal plane.

[0103] A number of seasoning buckets 31 are provided, and they perform a circulating self-rotation motion driven by the circulating pivot power mechanism 33. Each seasoning bucket 31 can also be set as a solid material bucket and a liquid material bucket according to the types of seasonings to be stored, and the solid material bucket can be set as different bucket mechanisms according to the particle sizes of the solid seasonings. In order to cooperate with the circulating self-rotation motion of each seasoning bucket 31, the bucket fixing seat 32 is set in a cylindrical shape, and the above-mentioned seasoning buckets 31 are circumferentially hung on the outer side surface of the bucket fixing seat 32. Correspondingly, hooks or hanging holes are provided on the outer side surface of the bucket fixing seat 32, and corresponding hanging holes or hooks are provided on the back surfaces of the seasoning buckets 31.

[0104] The annular rack 332 is fixed to the inner side surface of the bucket fixing seat 32. In this way, the precise feeding machine 30 can perform a circulating self-rotation motion driven by the circulating pivot power mechanism 33. In addition, in order to cooperate with the feeding of the seasonings in each seasoning bucket 31, a notch 361 is opened on the base 36. With such a setting, when the corresponding bucket rotates with the rotation of the bucket fixing seat 32 to the position above the notch 361, the stored seasonings can be discharged and fall through the notch 361. Correspondingly, the notch 361 is also connected to a feeding channel 362.

[0105] As Figure 4As shown in the figure, the seasoning bucket 31 specifically includes: a liquid material bucket 310, a first solid material bucket 320, and a second solid material bucket 330. The quantity of each of the above-mentioned seasoning buckets 31 is set according to requirements and is circumferentially mounted on the outer side surface of the bucket fixing seat 32.

The lower barrel body 312 is installed at the bottom of the upper barrel body 311 and is selectively connected to the upper barrel body 311 along with the opening or closing of the liquid outlet. At the same time, the air pipe passes through the upper barrel body 311, one end of which extends into the external environment, and the other end extends into the lower barrel body 312, thus maintaining the air pressure balance and facilitating the smooth outflow of the liquid.

[0108] 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 passes through the liquid outlet of the upper barrel body 311, and its lower end extends into the lower barrel body 312. The first spring is arranged between the lower end of the push rod 3182 and the end face of the liquid outlet, and the first spring is in a compressed state. In this way, by compressing the first spring, the plug cover 3181 can seal the liquid outlet at the bottom of the upper barrel body 311. 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.

[0109] The lower barrel body 312 has a horizontally arranged inner cavity 3121, one end of which is open and the other end is closed. And there is also an opening 31211 on the side wall of the inner cavity 3121.

One end of the liquid outlet pipe 313 extends out of the inner cavity 3121, and the extended end of the liquid outlet pipe 313 is T-shaped. One end of the T-shaped pipe head 3131 discharges liquid, and the other end is closed. Such a setting ensures that the residual liquid after 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.

[0110] The protruding end of the liquid outlet pipe 313 is installed at the open end of the inner cavity 3121 through a fixing sleeve 314. The fixing sleeve 314 includes: a fixing sleeve body 3141 and a clamp 3142 arranged on the outer side 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 passes through the fixing sleeve 314 body. A 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.

[0111] A cam 316 is sleeved on the liquid outlet pipe 313 and is 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. Thus, when the liquid outlet pipe 313 pivots, the cam 316 on it pivots synchronously, so that the cam 316 can push open the plug cover 3181 through the push rod 3182, making the liquid outlet opening at the bottom of the upper barrel body 311 open as described above, and enabling the liquid seasoning stored in the upper barrel body 311 to flow into the lower barrel body 312. When the liquid outlet pipe 313 pivots in the reverse direction, the cam 316 returns to its initial position, and the plug cover 3181 closes the liquid outlet at the bottom of the upper barrel body 311 again.

[0112] 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. The end face of the first top sleeve 3191 has two convex surfaces arranged centrosymmetrically. The second top sleeve 3192 also has two convex surfaces arranged centrosymmetrically. The first top sleeve 3191 cooperates with the second top sleeve 3192, and the convex surfaces on the first top sleeve 3191 extend 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 received and installed in the second top sleeve 3192 and can seal the opening 31211 at the other end of the liquid outlet pipe 313 under the action of the second spring 3194.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] The first blowing pipe 322 is used to blow out the solid condiment. It penetrates through the gear shaft 3231, and both ends of the first blowing pipe 322 extend out of the gear shaft 3231. The lower end of the first 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 blowing pipe 322, and a compression spring 3222 is arranged between the air nozzle 3221 and the first external gear disk 323. In this way, air can be introduced into the first blowing pipe 322 through the air nozzle 3221.

[0119] The first stirring mechanism 324 is used to disperse the solid condiment in the first barrel 321 so that the solid condiment can be discharged smoothly. The first stirring mechanism 324 includes: a stirring rod 3241 and multiple groups of stirring fins 3242.

[0120] Among them, the stirring rod 3241 is arranged outside the gear shaft 3231 through a frame body 3243. The frame body 3243 includes upper and lower relatively arranged rings and four connecting rods connecting the two rings. The number of stirring rods 3241 is several, and several stirring rods 3241 are connected to the rings and the connecting rods at their respective angles and extend towards the central stirring shaft. In one embodiment, two central stirring rods 3241 are connected to the upper ring, and one connecting rod is respectively connected to two relatively arranged connecting rods. A downwardly inclined stirring rod 3241 is respectively arranged at the connection of the lower ring and the connecting rod.

[0121] Multiple groups of stirring fins 3242 are sleeved on the above-mentioned gear shaft 3231 from top to bottom and can pivot synchronously with the gear shaft 3231. In one embodiment, there are three groups of stirring fins 3242. Among them, the upper two groups of stirring fins 3242 respectively have three stirring wings, and each stirring wing is inclined downward. The lowermost group of stirring fins 3242 has three stirring wings, and each stirring wing is inclined upward. And each stirring wing has a blade edge suitable for cutting into the solid condiment.

[0122] The material distributing disk 325 is sleeved on the lower end of the gear shaft 3231. It includes: a material distributing disk body 3251 and material distributing pieces 3252 arranged around the material distributing disk body 3251. Any material distributing piece 3252 can move along the material groove at the bottom of the first barrel 321. In this way, when the first external gear disk 323 drives the gear shaft 3231 to pivot, the material distributing disk 325 can dial out the dispersed solid condiment from the discharge of the material groove. At the same time, a kidney-shaped hole is also opened on any material distributing piece 3252.

[0123] The discharging unit 326 includes an internal gear disk 3261 and planetary gears 3262. The internal gear disk 3261 is located below the first barrel body 321, and at least one discharging opening is provided on the internal gear disk 3261. The lower end of the gear shaft 3231 is engaged with the internal gear disk 3261 through the planetary gears 3262. In this way, when the first external gear disk 323 drives the gear shaft 3231 to pivot, there is a rotational speed difference between the material shifting disk 325 and the internal gear disk 3261. Thus, when the discharging opening on the internal gear disk 3261 is aligned with the discharging opening of the material chute, the gear shaft 3231 can drive the material shifting disk 325 to push the solid condiment out from the discharging opening and the discharging opening. The pushed solid condiment drops into the bottom cover 3212. At this time, when the first air blowing pipe 322 is pressed down under an external force, the flap 3213 can be pushed open, and at the same time, the first air blowing pipe 322 blows air flow, so that the solid condiment dropped into the bottom cover 3212 is blown out.

[0124] Alternatively, in order to achieve quantitative discharging, in another embodiment, in addition to including a similar first barrel body 321, a first external gear disk 323, a first stirring mechanism 324, and a material shifting disk 325, the discharging unit 326 of the first solid material barrel 320 is improved and designed.

[0125] At this time, as Figure 6 shown, the discharging unit 326 in this embodiment further includes a transmission gear set 3263, a quantitative discharging disk 3264, and a material cavity 3265. The transmission gear set 3263 and the quantitative discharging disk 3264 are installed in the material cavity 3265, and an opening communicating with the space of the material cavity 3265 where the quantitative discharging disk 3264 is located is provided at the bottom of the first barrel body 321. The transmission gear set 3263 includes a first gear 32631 sleeved on the lower end of the gear shaft 3231, a second gear 32632 engaged with the first gear 32631 and pivotally connected in the material cavity 3265, a screw rod 32634 with a third gear 32633 engaged with the second gear 32632 sleeved at one end, and a fourth gear 32635 engaged with the screw rod 32634.

[0126] The quantitative discharging tray 3264 is disposed opposite to the bottom opening of the first barrel body 321, and a blanking port 32651 is further formed at the bottom of the material cavity 3265 opposite to the quantitative discharging tray 3264. The quantitative discharging tray 3264 includes end plates 32641 on both sides and paddles 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 tray 3264. Thus, when the first external gear disk 323 drives the gear shaft 3231 to pivot, the feeding tray 325 can pivot synchronously, and the solid seasonings in the first barrel body 321 can be dialed into the material cavity 3265 and fill the space between the two paddles 32642. The transmission gear set 3263 drives the quantitative discharging tray 3264 synchronously. Since the capacity between the paddles 32642 remains the same, the quantitative discharging tray 3264 discharges the solid seasonings quantitatively through the paddles 32642 thereon.

[0127] Alternatively, in order to adjust the discharging amount of the seasonings, in another embodiment, in addition to including a similar first barrel body 321, a first external gear disk 323, a first stirring mechanism 324, and a feeding tray 325, the first solid material barrel 320 improves the design of the discharging unit 326.

[0128] In this embodiment, as Figure 7 shown, the bottom cover 3212 is screwed to the bottom of the first barrel body 321.

[0129] The discharging unit 326 includes a spring 3266, an adjustment disk 3267, a fixed disk 3268, a planetary gear 3269, a material door 3270, and a material door cylinder 3271.

[0130] Among them, the fixed disk 3268 is located below the first barrel body 321, and a discharging port is provided on the fixed disk 3268. The lower end of the gear shaft 3231 is engaged with the fixed disk 3268 through the planetary gear 3269. The adjustment disk 3267 is disposed below the fixed disk 3268, and a discharging channel 32671 that can extend into the discharging port on the fixed disk 3268 and a guide post 32672 that can be inserted into the fixed disk 3268 are provided on the adjustment disk 3267. The discharging channel 32671 of the adjustment disk 3267 is communicated with the storage bin of the bottom cover 3212. The spring 3266 is disposed between the adjustment disk 3267 and the fixed disk 3268, and the spring 3266 is in a compressed state. With such a setting, when it is necessary to adjust the discharging amount, the bottom cover 3212 can be rotated so that the bottom cover 3212 is away from the fixed disk 3268. At this time, due to the elastic action of the spring 3266, the adjustment disk 3267 can be closely attached to the bottom cover 3212. Correspondingly, the volume between the storage bins of the bottom cover 3212 increases, achieving the purpose of adjusting the discharging amount.

[0131] Therefore, when the first outer gear disk 323 drives the gear shaft 3231 to pivot, there is a rotational speed difference between the material feeding disk 325 and the fixed disk 3268. Thus, when the material discharging opening on the fixed disk 3268 aligns with the discharging opening at the bottom of the first material barrel, the gear shaft 3231 can drive the material feeding disk 325 to push the solid condiment out from the discharging opening and the material discharging opening, and enter the material bin through the material discharging channel 32671. At this time, the material door cylinder 3271 drives the material door 3270 to open the discharging opening at the bottom of the material bin, realizing the quantitative discharging of the solid condiment.

[0132] The second solid material barrel 330 is used for storing large-particle solid condiments, and it can grind the large-particle solid condiments to form small-particle or powdered solid condiments.

[0133] As Figure 8 shown, the second solid material barrel 330 includes: a second barrel body 331, a second air blowing pipe 332, a second outer gear disk 333, a second stirring mechanism 334, and a grinding mechanism 335.

[0134] The inside of the second barrel body 331 is used for storing large-particle solid condiments. Its top is provided with a barrel cover 3311, and its bottom is provided with a discharging opening, which is opened or closed by a bottom cover 3312. Specifically, the bottom cover 3312 is screwed to the discharging opening, and it has a sealing cover 3313 for opening or closing the discharging opening. Moreover, a feeding opening is also provided on the outer side wall of the second barrel body 331, and the feeding opening is opened or closed by a material door 3314.

[0135] The second outer gear disk 333 is installed on the top of the barrel cover 3311. The second outer gear disk 333 is in transmission connection with the grinding mechanism 335 through a gear shaft 336 axially penetratingly arranged. In this way, when the second outer gear disk 333 pivots, it can drive the grinding mechanism 335 connected to it in transmission to perform grinding.

[0136] The second air blowing pipe 332 is used for blowing out the ground solid condiments. It penetrates through the gear shaft 336, and both ends of the second air blowing pipe 332 extend out from the gear shaft 336. The lower end of the second air blowing pipe 332 is connected to the sealing cover 3313. Thus, when the second air blowing pipe 332 presses down, it can drive the sealing cover 3313 to move synchronously to open the discharging opening it closes. 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 disk 333. In this way, air can be introduced into the second air blowing pipe 332 through the air nozzle 3321. In addition, the peripheral edge of the sealing cover 3313 is set as a slope suitable for closing the discharging opening, and a plurality of air outlet holes are circumferentially arranged on the slope. The plurality of air outlet holes are respectively communicated with the lower end of the second air blowing pipe 332 through an air passage inside the sealing cover 3313.

[0137] The second stirring mechanism 334 is used to disperse the solid condiments in the second barrel body 331 so that the solid condiments can be smoothly ground. The second stirring mechanism 334 includes: a stirring rod 3341 and multiple groups of stirring fins 3342.

[0138] Among them, the stirring rod 3341 is arranged outside the gear shaft 336 through a frame body 3343. The frame body 3343 includes a circular ring arranged oppositely up and down and four connecting rods connecting the two circular rings. There are several stirring rods 3341, and the several stirring rods 3341 are connected to the circular ring and the connecting rods according to their respective angles and extend towards the central stirring shaft. In one embodiment, two central stirring rods 3341 are connected to the upper circular ring, and one connecting rod is respectively connected to two oppositely arranged connecting rods. A downwardly inclined stirring rod 3341 is respectively arranged at the connection of the lower circular ring and the connecting rod.

[0139] Multiple groups of stirring fins 3342 are sleeved on the above-mentioned gear shaft 336 from top to bottom and can pivot synchronously with the gear shaft 336. In one embodiment, there are four groups of stirring fins 3342. Among them, the upper two groups of stirring fins 3342 respectively have three stirring fins, and each stirring fin is inclined downward. The lower two groups of stirring fins 3342 respectively have three stirring fins, and each stirring fin is inclined upward. And the width of the lowermost group of stirring fins is greater than the width of each group of stirring fins above it. And each stirring fin has a cutting edge suitable for cutting into solid condiments.

[0140] The grinding mechanism 335 is used to grind large-particle solid condiments to form small-particle or powdered solid condiments. The grinding mechanism 335 includes: a grinding inner tooth 3351 and a grinding outer tooth 3352.

[0141] Among them, the grinding inner tooth 3351 is installed at the lower end of the gear shaft 336. The grinding inner tooth 3351 is generally in a conical shape, and a number of circumferentially spaced grinding inner teeth 3351 are formed on its conical surface. A feeding groove is formed between the grinding inner teeth 3351. First main grinding edges 33511 are formed on both side edges of any grinding inner tooth 3351, and circumferentially arranged first secondary grinding edges 33512 are also formed on the four peripheral edges of one end of the grinding inner tooth 3351. The above-mentioned first main grinding edges 33511 and first secondary grinding edges 33512 are inclined according to the pivoting direction. The grinding outer tooth 3352 is arranged in the bottom cover 3312. Correspondingly, the grinding outer tooth 3352 has second main and secondary grinding edges 33521 and 33522 corresponding to the first main and secondary grinding edges on the grinding inner tooth 3351.

[0142] 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.

[0143] In addition, according to actual needs, a barrel for storing viscous substances and / or sauces may also be provided.

[0144] like Figure 9 , 10 As shown, the feeding mechanism 35 is used to control the precise feeding machine 30 to feed when the material barrel in the precise feeding machine 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.

[0145] The unloading mechanism 35 includes a liquid unloading unit 351 and a solid unloading unit 352 .

[0146] The liquid unloading unit 351 includes a push plate 3511 , a connecting frame 3512 , a fixing plate 3513 and a first pivoting motor 3514 .

[0147] Among them, the first pivot motor 3514 is fixed on the base 36, and is connected to one end of the screw rod 3516 through a transmission belt 3515. The lower end of the connecting frame 3512 is connected to the 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 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.

[0148] 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.

[0149] 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 .

[0150] 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.

[0151] 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.

[0152] The buffer structure 3523 is used to provide a buffering force when the driving gear 3521 meshes with the outer gear disc. And the buffer structure 3523 can also provide a fine-tuning force when the driving gear 3521 and the outer gear discs 323 and 333 are not fully meshed, so that the two can be well matched together. Specifically, the buffer structure 3523 includes: a retaining piece 35231, a spring 35232 and a stop block 35233. Among them, the retaining piece 35231 is a U-shaped structure, and its two ends are respectively connected to the two ends of the pivot of the driving gear 3521. The stop block 35233 is located on one side of the retaining piece 35231 and is fixed to the push plate 3511. The spring 35232 is arranged between the retaining piece 35231 and the stop block 35233 and is in a compressed state. In this way, the spring 35232 provides a force for the driving gear 3521 to achieve the above buffering and fine-tuning effects.

[0153] As Figure 11 shown, the air supply structure 3524 is used to provide a blowing air flow for the above-mentioned air pipe, the first blowing pipe 322 and the second blowing pipe 332.

[0154] 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 its end is provided with an air outlet nozzle arranged downward. The swing assembly 35242 includes: a guide plate 352421 and a pivot mounting seat 352422. 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 connecting sleeve 3524222. The fixed seat 3524221 is mounted on the vertical plate 3342 and is located on one side of the push plate 3511. One end of the pivot connecting 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.

[0155] The guide plate 352421 is provided with a guide groove 3524211 that is inclined downward toward the blanking position. At the same time, another pivot connecting sleeve 3524222 is also sleeved on the air supply pipe 35241. A pin is inserted between one end of the pivot connecting sleeve 3524222 and the guide groove, and the pin is initially located at the end of the guide groove close to the blanking position. The other pivot connecting sleeve 3524222 is located behind the pivot mounting seat 352422.

[0156] 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.

[0157] Again Figure 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 precision feeder 30 is located, and is located on the inner side of the barrel fixing seat 32.

[0158] 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 lead screw 3516 which is transmission-connected to the first pivot motor 3514 is pivotally connected to the bottom of the guide arm 342 .

[0159] 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.

[0160] Again Figure 1 As shown, the second feeding device 40 is used to supply consumables with large amounts of cooking oil and the like during cooking, and it works synchronously or asynchronously with the precision feeding machine 30. The second feeding device 40 includes a plurality of feeding units 41, and any feeding unit 41 includes: a storage barrel 42, a pressure storage barrel 43, a metering barrel 44, and a discharge control valve 45.

[0161] Among them, the storage barrel 42, the pressure storage barrel 43, the metering barrel 44, and the discharge control valve 45 are connected in sequence through pipelines. The metering barrel 44 and the discharge control valve 45 are integrated on the secondary rotating arm 24 and are located below the precise feeding machine 30, so as to facilitate pivoting feeding driven by the secondary rotating arm 24. The storage barrel 42 and the pressure storage barrel 43 are separately arranged from the precise feeding machine 30.

[0162] The storage barrel 42 is used to store consumables such as edible oil with a large consumption. The storage barrel 42 is a hollow barrel body, and an interface convenient for pipeline connection is provided at the top thereof, and the interface is in communication with the inside of the barrel body.

[0163] As Figure 12 shown, the pressure storage barrel 43 can receive consumables such as edible oil with a large consumption from the storage barrel 42 and is used to keep the edible oil and the like flowing out quantitatively and stably 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 lock hoop 434, a regulating valve 435, and a dividing cut-off valve 436.

[0164] Among them, the barrel body 431 is fixed to the upper layer of the material rack 46 through the barrel seat 432. The barrel cover 433 is used to open or close the barrel body 431. It is buckled on the top of the barrel body 431 and locked through the barrel cover lock hoop 434, and a pipeline interface 4331 is provided on the barrel cover 433. Considering that the pressure inside the barrel body 431 will change as the edible oil and the like continue to flow out, an external air source interface 4332 and a pressure gauge 4333 are also provided on the barrel cover 433. In this way, when the edible oil and the like continue to flow out, pressure gas can be introduced through the external air source interface to compensate the internal pressure so that the pressure inside the barrel body 431 remains constant. The barrel cover lock hoop 434 can adopt an existing lock hoop. The barrel cover lock hoop 434 has locking arms pivotally connected at both ends, and the two locking arms can be locked and connected through a bolt.

[0165] A flow-out pipeline is connected to the bottom of the barrel body 431, and the regulating valve 435 and the dividing cut-off valve 436 are installed on the flow-out pipeline. As Figure 13As shown in the figure, the regulating valve 435 includes: a regulating valve body 4351, a regulating valve rod 4352, a handle 4353, and a regulating tooth piece 4354. The inside of the regulating valve body 4351 is vertically and horizontally penetrated, and the regulating valve body 4351 has a pipe interface communicating with the internal horizontal pipe. The regulating valve body 4351 is connected to the outflow pipe through the pipe interfaces at both ends. At the same time, the pipe interface and the outflow pipe are locked by a hoop 4355. The regulating valve rod 4352 is pivotally disposed in the internal longitudinal pipe of the regulating valve body 4351, and a valve piece 43521 is further provided on the regulating valve rod 4352. The valve piece 43521 is located at the intersection of the internal vertical and horizontal pipes of the regulating valve body 4351. Thus, when the regulating valve rod 4352 pivots, the opening degree at the intersection of the internal vertical and horizontal pipes of the regulating valve body 4351 can be adjusted through the valve piece thereon, thereby changing the flow rate inside the outflow pipe.

[0166] One end of the handle 4353 is connected to the upper end of the regulating valve rod 4352 and can drive the regulating valve rod 4352 to pivot. At the same time, a locking tooth 43531 is also provided at the end of the handle 4353 connected to the regulating valve rod 4352. The regulating tooth piece 4354 is installed at the end of the handle 4353 connected to the regulating valve rod 4352. The regulating tooth piece 4354 is provided with a circumferentially spaced arrangement of card slots that can cooperate with the locking teeth. With such a setting, when the handle 4353 drives the regulating valve rod 4352 to pivot to the required angle, the locking tooth 43531 thereon can cooperate with the card slot at the corresponding angle to keep the position of the regulating valve rod 4352 fixed and prevent it from freely pivoting.

[0167] As Figure 14 As shown in the figure, the split stop valve 436 is used to control the opening and closing of the outflow pipe, and it includes: a split stop valve body 4361, a split stop valve rod 4362, and a valve body cylinder 4363. The inside of the split stop valve body 4361 is vertically and horizontally penetrated, and the split stop valve body 4361 has two pipe interfaces communicating with the internal horizontal pipe. The split stop valve body 4361 is connected to the outflow pipe through the two pipe interfaces. At the same time, the pipe interface and the outflow pipe are locked by a hoop. In another embodiment, the two pipe interfaces on the split stop valve body 4361 are perpendicular. The split stop valve rod 4362 is disposed in the internal longitudinal pipe of the split stop valve body 4361, and the split stop valve rod 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 pipe where it is located.

[0168] 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 cut-off 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 cut-off valve body 4361. In one embodiment, the valve body cylinder 4363 is installed and fixed through two first columns 4365. At this time, the split cut-off valve rod 4362 is located between the two first columns 4365. In addition, to facilitate the maintenance inside the split cut-off valve body 4361, the split cut-off valve body 4361 is also provided with an inspection opening communicating with the internal horizontal pipeline, and an inspection cover is screwed at the inspection opening.

[0169] The volume of the metering cylinder 44 is smaller than that of the pressure storage cylinder 43. The metering cylinder 44 is used to receive consumables such as edible oil in large quantities from the pressure storage cylinder 43, and together with the pressure storage cylinder 43, it realizes quantitative discharging under a constant pressure. The advantage of setting the metering cylinder 44 to cooperate with the pressure storage cylinder 43 for quantitative discharging is that the volume of a single pressure storage cylinder 43 is relatively large, making it inconvenient to control the precise outflow of consumables such as edible oil stored inside. However, inputting consumables such as edible oil from the pressure storage cylinder 43 into a metering cylinder 44 with a smaller volume is conducive to controlling the precise discharging of consumables such as edible oil in the metering cylinder 44.

[0170] As Figure 15 shown, the metering cylinder 44 includes: a cylinder body 441, a top cover 442, a bottom cover 443, a feed pipe 444, and a discharge pipe 445.

[0171] Among them, the cylinder body 441 is provided in a through manner. Considering that the pressure inside the cylinder body 441 will change with the continuous outflow of consumables such as edible oil, a piston 446 is further provided inside the cylinder body 441. The four peripheral edges of the piston 446 are in contact with the inner wall surface of the cylinder body 441, and a sealing ring is provided between the four peripheral edges of the piston 446 and the inner wall surface of the cylinder body 441. The piston 446 divides the inside of the cylinder body 441 into two independent cavities, the upper cavity being an air cavity and the lower cavity being a storage cavity. With such a setting, by compensating the pressure in the air cavity, the consumables such as edible oil in the storage cavity can be quantitatively discharged under a constant pressure in the air cavity.

[0172] The top cover 442 is screwed onto the top opening of the graduated cylinder body 441 to close the top opening of the graduated cylinder body 441. Correspondingly, in order to introduce external gas into the air chamber to maintain a constant pressure, a gas interface is also provided on the top cover 442, and gas for maintaining a constant pressure can be introduced into the interior of the graduated cylinder body 441 through this gas interface. The bottom cover 443 is screwed onto the bottom opening of the graduated cylinder body 441 to close the bottom opening of the graduated cylinder body 441. The feed pipe 444 and the discharge pipe 445 are connected to the bottom cover 443 and are in communication with the interior of the graduated cylinder body 441. The feed pipe 444 is connected to the pressure storage cylinder 43 through a pipeline, and the discharge pipe 445 is connected to the discharge control valve 45 through a pipeline. In this way, the material from the pressure storage cylinder 43 can enter the storage chamber of the graduated cylinder body 441 through the feed pipe 444 and be discharged quantitatively through the discharge pipe 445.

[0173] As Figure 16 shown below, taking edible oil as an example, when a 4.5L pressure storage cylinder 43 and a 250mL measuring cylinder 44 are used, the principle of quantitative discharge control for the storage barrel 42, the pressure storage cylinder 43, the measuring cylinder 44, and the discharge control valve 45 will be introduced:

[0174] Let the air pressure in the pressure storage cylinder 43 be P1, the volume of the edible oil be V1, and the liquid level height of the edible oil in the pressure storage cylinder 43 be δH;

[0175] Design the air pressure in the measuring cylinder 44 to be P3, the oil pressure to be P2, and the liquid level height of the edible oil in the measuring cylinder 44 to be δh and the volume to be V2;

[0176] Let the distance between the bottom of the pressure storage cylinder 43 and the bottom of the measuring cylinder 44 be H;

[0177] Let the volume of the edible oil in the pipeline connecting the bottom of the pressure storage cylinder 43 and the bottom of the measuring cylinder 44 be δV.

[0178] Since it is known that ρoil = 0.9g / cm 3 = 0.9X10 3 Kg / m 3 , g = 9.8N / Kg, 1bar = 9.8N / cm 2 . When P1 = 4bar = 39.2N / cm 2 , then P2 = P1 + ρ 油 *g*(δH + H - δh).

[0179] When the pressure storage cylinder 43 is filled with oil for the first time, since δH = V1 / πR1 2 , δh = V2 / πR2 2 , the first filling volume V0 of the pressure storage cylinder 43 = V1 + V2 + δV, then δH = (V0 - δhπR2 2-δV) / πR1 2 。

[0180] Since P3 = P2, then P3 = P1 + ρ 油 *g*(δH + H - δh) P3 = P1 + ρ 油 *g*(V0 - δhπR2 2 -δV) / πR1 2 +ρ 油 *g*H - ρ 油 *g*δh。

[0181] It can be seen therefrom that δh = (P3 - P1 - ρ 油 *g*[(V0 - δV) / πR1 2 + H]) / (ρ 油 *g*(1 - πR2 2 / πR1 2 ))。

[0182] Thus, for the quantitative discharging of the edible oil in the measuring cylinder 44, the air pressure P3 in the measuring cylinder 44 can be controlled, so as to control the liquid level height δh of the edible oil in the measuring cylinder 44, so that the measuring cylinder 44 provides the edible oil V2 with the liquid level height of δh each time. The distance H between the bottom of the pressure storage cylinder 43 and the bottom of the measuring cylinder 44 can be positive, negative or zero. Correspondingly, the pressure storage cylinder 43 can be arranged higher than the measuring cylinder 44, lower than the measuring cylinder 44, or at the same height as the measuring cylinder 44.

[0183] As Figure 17 shown, the discharging control valve 45 is used to open or close the discharging pipe 445 of the measuring cylinder 44 connected thereto. The discharging control valve 45 includes: a control valve body 451, a control valve rod 452, a discharging air cylinder 453 and a discharging nozzle 454.

[0184] Wherein, the control valve body 451 has an axially penetrating material passage inside. The control valve rod 452 is pivotally disposed in the material passage inside the control valve body 451, and one end of the control valve rod 452 is connected to the discharging air cylinder 453 and can be driven by the discharging air cylinder 453 to perform axial telescopic movement to open or close the material passage inside the control valve body 451.

[0185] For the convenience of installation and fixation of the discharging air cylinder 453, the discharging air cylinder 453 is installed on the upper end surface of the control valve body 451 through the second column 455, and a gasket 456 is further arranged between the second column 455 and the upper end surface of the control valve body 451. In one embodiment, the discharging air cylinder 453 is installed and fixed through two second columns 455. At this time, the control valve rod 452 is located between the two second columns 455.

[0186] In order to be connected to the discharge pipe 445, a pipe interface communicating with the internal material passage is integrally extended on the control valve body 451. The pipe interface can be connected to the discharge pipe 445 through a bent pipe or a straight pipe 457, and the pipe interface and the discharge pipe 445 can be locked tightly through a hoop 458. The discharge nozzle 454 is screwed to the outlet of the material passage of the control valve body 451, and a sealing ring is also arranged between the discharge nozzle 454 and the control valve body 451.

[0187] As described above, the second feeding device 40 includes a plurality of feeding units 41. Thus, according to actual requirements, 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 arranged side by side at the lower layer of the material rack 46, and the pressure storage cylinders 43 of the six groups of feeding units 41 are arranged side by side at the upper layer of the material rack 46. Since the metering cylinder 44 and the discharge control valve 45 are integrated on the secondary rotating arm 24, in this embodiment, as Figure 18 shown, the metering cylinders 44 of the six groups of feeding units 41 are integrated on the secondary rotating arm 24 through a horizontally arranged seat plate 47, and at the same time, the discharge control valves 45 of the six groups of feeding units 41 are integrated at the end of the secondary rotating arm 24 through a vertically arranged seat plate 48. In the arrangement mode, the metering cylinders 44 of the six groups of feeding units 41 are symmetrically distributed left and right, and the discharge control valves 45 of the six groups of feeding units 41 are correspondingly symmetrically distributed left and right.

[0188] As Figure 19 shown, the water replenishing device 50 is used to provide cold water and / or hot water required during cooking. The water replenishing device 50 is integrated at the bottom of the secondary rotating arm 24, and it includes: a cold water supply mechanism 51, a hot water supply mechanism 52, a water purification mechanism (not shown), and a first outer cover 53 and a second outer cover.
