As shown in fig. 6, the stirring unit 31 is used to stir the solid seasoning stored in the upper space, so as to disperse the solid seasoning for easy discharge. The stirring unit 31 includes: a stirring rod 310, a stirring rod 311, a stirring blade 312, a holder 313 and a gear set 314.

The gear set 314 includes: a first driven gear 3140 and a second driven gear 3141.

Wherein, the first driven gear 3140 and the second driven gear 3141 are pivotally connected to the top of the cover plate 33 and are engaged with each other. Meanwhile, by providing a driving gear, it can be engaged with the first driven gear 3140. When the driving gear works, the first driven gear 3140 in transmission connection with the driving gear can be driven to synchronously pivot. Thus, the first driven gear 3140 can further drive the second driven gear 3141 to rotate.

The lower end of the gear shaft of the second driven gear 3141 forms a drive connection end that passes through the top cover and extends into the first housing 30. In order to be connected with the molding block at the upper end of the stirring rod 310 in a transmission manner, a groove 31410 capable of being matched with the molding block is further formed on the end face of the transmission connecting end. Thus, when the second driven gear 3141 rotates, the stirring rod 310 is driven to rotate synchronously.

Meanwhile, in order to limit the second driven gear 3141 in the radial direction, a gasket 315 is further sleeved on the gear shaft, and the gaskets 315 are distributed on the upper side and the lower side of the cover plate 33. Correspondingly, the gear shaft is also provided with an annular groove suitable for sleeving the gasket 315. In addition, a protective cover 37 is disposed on the cover plate 33, the first driven gear 3140 and the second driven gear 3141 are accommodated in the protective cover 37, and the first driven gear 3140 at least partially protrudes from the protective cover 37.

As described above, the first driven gear 3140 and the second driven gear 3141 are mounted on the cover plate 33. In this manner, the second driven gear 3141 may be disengaged from the agitator arm 311 when the cover 33 is opened. Therefore, in order to allow the second driven gear 3141 to be re-engaged with the stirring rod 310 when the cover plate 33 is engaged, the second driven gear 3141 is provided with a hexagonal adjustment hole 31411 at the center thereof, and a tool is inserted into the hexagonal adjustment hole 31411 to control the rotation of the second driven gear 3141, thereby aligning the second driven gear 3141 with the stirring rod 310. Correspondingly, the protective cover 37 is provided with a hole 370 exposing the hexagonal adjusting hole 31411.

The holder 313 is used for fixing the agitating bar 310 in the first housing 30, and includes: an outer frame 3130 and an inner hub 3131. The four corners of the outer frame are respectively locked to the corresponding connecting columns inside the first casing 30 through bolts. The inner bushing 3131 is positioned inside the outer frame 3130, and the inner bushing 3131 is integrally connected to the outer frame 3130 by a connection rib 3132. Meanwhile, the inner bush 3131 is further fitted over the upper portion of the agitating bar 310 to fix the agitating bar 310 in the first housing 30. The upper and lower sides of the holder 313 are also provided with backing plates corresponding to the shape thereof. Further, the lower end of the stirring rod 310 is pivotally connected to a spindle provided on the partition 301, and the spindle is maintained coaxially with the inner hub 3131. Thus, the stirring rod 310 can rotate around its own axis by the gear set 314.

The stirring rods 311 are multiple, the stirring rods 311 are movably inserted in the stirring rod 310 in a transverse direction, and the stirring rods 311 are arranged at intervals from top to bottom. Correspondingly, the stirring rod 310 is provided with through holes which are arranged at intervals from top to bottom and are suitable for the insertion of the stirring rods 311. Thus, when the stirring rod 310 rotates, the stirring rods 311 thereon are driven to rotate synchronously, and the solid seasonings stored in the upper space are scattered. Meanwhile, as the plurality of stirring rods 311 are movably arranged, the length of the stirring rods 311 penetrating through the stirring rod 310 can be adjusted according to needs, so that the stirring requirement of different types of solid seasonings can be met.

Furthermore, the stirring rod 310 is further provided with bolt holes 3100 arranged adjacent to the through holes at intervals from top to bottom, and any through hole is communicated with one bolt hole 3100. Therefore, the through-hole stirring rod 311 can be locked and fixed through the bolt, so that the stirring rod 311 can be fixed after the through-length is adjusted. In addition, a protrusion 3110 having a size larger than the diameter of the stirring rod 311 is further provided at an end of any one of the stirring rods 311. Thus, any stirring rod 311 has a larger contact area with the solid seasoning, thereby being beneficial to fully scattering the solid seasoning. And the shape and size of the projections on each stirring rod 311 may be the same or different. In one embodiment, the protrusion is a ball disposed at an end of the stirring rod 311.

The stirring blade 312 includes: at least two blade bodies and a lantern ring connecting each blade body. The stirring blade 312 is mounted to the lower end of the stirring rod 310 through a collar thereof, so that the bottom of the solid seasoning stored in the upper space can be agitated and scattered. In order to realize the transmission between the stirring blades 312 and the stirring rod 310, a polygonal assembly hole is formed in the middle of the lantern ring.

As shown in fig. 7, the first discharging unit 32 is used to control the discharge of the solid seasoning above. The first discharging unit 32 includes: at least one magazine 320. The magazine 320 is drawably disposed in the lower space of the first casing 30, and receives the solid seasoning stored in the upper space and discharges the solid seasoning while being drawn out. Accordingly, the lower space of the first housing 30 has front and rear oppositely disposed openings communicated to the outside.

Wherein the rear end of the magazine 320 protrudes from the lower space thereof. And magazine 320 has a plurality of silos 3200 that link up the setting from top to bottom, and a plurality of silos 3200 are arranged according to magazine 320's pull direction interval. Therefore, the pulling distance of the material box 320 can be controlled according to the gram of the solid seasoning required, so that the material grooves 3200 with corresponding quantity leak the material. For example, if 1g of solid seasonings can be stored in one trough 3200, when 3g of solid seasonings are needed, the distance of pulling out the magazine 320 can be controlled to expose three troughs 3200, so as to obtain 3g of solid seasonings.

In order to facilitate each trough 3200 to receive the solid seasonings stored in the upper space, a discharge hole 3010 is formed in the partition 301 inside the first housing 30. When the magazine 320 is initially located in the lower space of the first housing 30, the trough 3200 thereon is disposed opposite to the discharge port 3010 of the partition 301. Thus, the solid seasoning can drop into the trough 3200 through the discharge hole 3010. In addition, the stirring blade 312 is also convenient for the solid seasonings to fall down and fill the material grooves 3200 below through stirring the solid seasonings.

In order to facilitate the drawing action of the magazine 320, the lower portion of the first housing 30 is further provided with a slide between the front and rear openings. This slide includes: an upper ramp plate 321 and a lower ramp plate 322. The upper sliding plate 321 is mounted at the bottom of the partition plate 301, and has a hollow area opposite to the discharge hole 3010. One end of the lower chute plate 322 is connected to the bottom of the front opening of the first casing 30, and the other end is connected to the protrusion extending from the bottom of the partition 301. Thus, the upper and

lower slide plates

321 and 322 form the slide between them, which is suitable for the magazine 320 to slide.

In order to further ensure the stability of the magazine 320 during drawing, the bottom of the magazine 320 is further connected to a guiding rail 3201, and correspondingly, the first housing 30 is further provided with a guiding chute matching with the guiding rail 3201. Thus, when the magazine 320 slides along the slide, the guide rail 3201 at the bottom thereof is guided along the guide slide groove in synchronization.

As described above, the material leaking from the material trough 3200 can be controlled in a corresponding amount according to the gram quantity of the required solid seasoning. When a larger number of grams of solid seasoning is desired, a plurality of pods 320 may be provided. In one embodiment, there are three magazines 320. At this time, the three magazines 320 are circumferentially arranged in the lower space of the first housing 30, and the adjacent magazines 320 have the same included angle. Thus, the chassis can drive the solid seasoning storage mechanism 300 to pivot, so that the corresponding magazine 320 moves to the blanking position.

Accordingly, spout 414 is connected to spout 412 and spout 415 by a tee 419, and the volume inside bladder 416 is at least greater than the sum of the volumes of spout 415 and spout 414, so as to prevent liquid from flowing back into the bladder. In order to fix the air bag 416, the first tube clamp 4111 is provided with a third cavity for accommodating and clamping the air bag 416.

In addition, in order to squeeze the air bag 416, a pressing block 420 is further pivotally connected to the first tube clamp 4111, and the pressing block 420 is located above the air bag 416 and can squeeze the cavity through its own pivot, so that the gas in the cavity is discharged, and further the residual liquid in the liquid outlet nozzle 414 is blown out. Correspondingly, the liquid seasoning storage mechanism is also provided with a swinging block which can be driven by a motor through a speed reducer to pivot. Thus, when the swing block swings pivotally, the pressing block 420 can be driven to pivot, and the air bag 416 is squeezed to blow air.

As shown in fig. 13 and 14, the discharging driving mechanism 50 realizes the discharging of the solid seasoning by driving the pulling of the cartridge in the solid seasoning storing mechanism 300, and realizes the discharging of the liquid seasoning by driving the pulling of the piston 413 in the liquid seasoning storing mechanism 400. This ejection of compact actuating mechanism 50 includes: a pull rod 51, a first laser sensor 52, a stepping motor 53, a speed reducer 54, a first driving wheel 55, a second driving wheel 56, a third driving wheel 57 and a driving belt 58.

Wherein, one end of the pull rod 51 is provided with a projection 510, and the projection 510 can be matched with the extending tail end of the magazine and the extending tail end of the piston 413, so as to control the drawing of the magazine and the piston 413. The position of the pull rod 51 thus defines the blanking position. Accordingly, the rear end of the magazine 320 and the rear end of the piston 413 are provided with downwardly arranged

catches

3202, 4130 capable of cooperating with the projection 510. The other end of the pull rod 51 is in transmission connection with a power structure formed by a stepping motor 53, a speed reducer 54, a first transmission wheel 55, a second transmission wheel 56 and a transmission belt 58, and the power structure can drive the pull rod 51 to move forward or backward.

Thus, when the bump 510 is accommodated in the corresponding material box or the bayonet at the tail end of the piston 413, the transmission structure drives the pull rod 51 to move forward, so that the solid seasoning in the material box can be discharged; when the transmission structure drives the pull rod 51 to retreat, the piston 413 can suck liquid seasoning, and when the transmission structure drives the pull rod 51 to reset, the sucked liquid seasoning can be discharged. Accordingly, the bayonets of the cartridges and the piston 413 are distributed on a circular track, and the extension line of the pull rod 51 in the length direction passes through the center of the circular track. Meanwhile, when each cartridge and the piston 413 are located at the blanking position, the extension line thereof in the drawing direction can overlap with the pull rod 51.

The first laser sensor 52 is installed at one end of the pull rod 51 and is disposed near the protrusion 510 on one end of the pull rod 51, and is used to detect whether the cartridge or the piston 413 is smoothly engaged with the protrusion 510 on the pull rod 51, and whether the cartridge is mounted on the solid seasoning storage mechanism 300 and the piston 413 is mounted on the liquid seasoning storage mechanism 400.

The first laser sensor 52 has a slot 520, and the slot 520 forms a correlation optical path therein. Accordingly, a

stop

3203, 4131 is provided at the rear end of each magazine 320 and piston 413, respectively. When the solid seasoning storage mechanism 300 or the liquid seasoning storage mechanism 400 is discharged, if the opposite light path is blocked, it indicates that the seasoning storage mechanism is equipped with the magazine 320 or the piston 413, and the protrusion 510 of the pull rod 51 is smoothly matched with the

bayonets

3202, 4130. This facilitates the subsequent operation of the pull rod 51.

As described above, the power structure can drive the pull rod 51 to advance or retreat. Specifically, the first driving wheel 55 and the second driving wheel 56 are arranged at intervals along the moving direction of the pull rod 51, and a bearing is further arranged between the wheel axle of each driving wheel and the fixed seat where the wheel axle is located.

The third transmission wheel 57 is located above the first transmission wheel 55 and the second transmission wheel 56, and the three transmission wheels are linked through a transmission belt 58, and the three transmission wheels keep the transmission belt 58 in a tensioned state. The stepping motor 53 is in transmission connection with a third transmission wheel 57 through a speed reducer 54. The belt 58 generally forms a triangle, depending on the arrangement of the three drive wheels. At this time, the pull rod 51 is connected to the belt 58 between the first and second driving wheels. In this way, when the stepping motor 53 drives the third transmission wheel 57 to pivot through the speed reducer 54, the transmission belt 58 can drive the pull rod 51 to move forward or backward.

In order to make the pull rod 51 perform stable linear reciprocating motion, the discharging driving mechanism 50 further includes: a slide 59 and a guide 591. At this time, the guide rail 591 is located at one side of the pull rod 51. The pull rod 51 is connected to the drive belt 58 by means of a slide 59, and the slide 59 is at the same time able to slide along the guide rail 591. In this way, the slider 59 can be guided and slid along the guide rail 591 while the pull rod 51 is advanced or retracted.

In addition, the third transmission wheel 57 can be adjusted up and down, so that the distance between the third transmission wheel 57 and the first transmission wheel 55 and the second transmission wheel 56 below the third transmission wheel can be adjusted, and further the continuous tensioning of the transmission belt 58 can be realized by the aid of the three transmission wheels. Accordingly, the stepping motor 53 and the reducer 54 are integrally adjustably mounted to the housing 593 through a connecting plate 592. Wherein, the machine base 593 is provided with a waist-shaped adjusting hole and an adjusting groove. The connecting plate 592 is locked to the housing 593 by a bolt passing through a kidney-shaped adjustment hole, and the slider 59 on the connecting plate 592 is capable of guided sliding along the adjustment groove while the connecting plate 592 is adjusted up and down. In one embodiment, the waist-shaped adjusting holes are respectively opened at both sides of the upper portion of the machine base 593, and the adjusting groove is opened at the area between the waist-shaped adjusting holes at both sides.

Although the stepping motor 53 can control the movement of the pull rod 51 by a certain stroke, the precise movement of the pull rod 51 by the stepping motor 53 cannot be realized. Therefore, precise movement of the pull rod 51 by means of the stroke control mechanism 60 is required.

The stroke control mechanism 60 is used to control the distance that the pull rod 51 advances or retreats to achieve accurate discharge of the solid seasoning and the liquid seasoning. This arrangement takes into account that the movement travel of the cartridge and therefore of the piston 413 drawn is linked to the quantity of seasoning discharged. For example, when the material box moves a certain distance to pull out a trough on the material box, the discharging of solid seasoning of one trough by weight is correspondingly realized; when the piston moves a certain distance and a certain volume of liquid seasoning flows out, the discharging of the liquid seasoning with corresponding volume parts is realized. Therefore, the accurate quantitative discharging of the solid seasoning and the liquid seasoning can be realized by accurately controlling the movement distance of the pull rod 51.

The stroke control mechanism 60 is located on one side of the discharge drive mechanism 50, and includes: a second laser sensor 61, a shutter 62, a position sensing switch 63, and a grating ruler 64.

The grid ruler 64 is located at one side of the pull rod 51, and has a plurality of grids closely arranged along the linear motion direction of the pull rod 51, and the grids cover the motion stroke of the pull rod 51. The second laser sensor 61 is connected to the belt 58 between the first transmission wheel 55 and the second transmission wheel 56. Thus, the second laser sensor 61 can move synchronously with the advance or retreat of the draw bar 51. Meanwhile, the second laser sensor 61 has a notch in which a correlation optical path is formed. The notches of the second laser sensor 61 extend to the bars of the grid ruler 64.

Thus, when the stepping motor 53 is operated, it can drive the second laser sensor 61 to move synchronously with the pull rod 51, and make its notch move relatively along the bars of the grating ruler 64. Because gaps are formed among the plurality of grids, when the notch moves along the plurality of grids relatively, the correlation light path in the notch is periodically shielded and communicated, and the communication of the correlation light path is performed every two times, which indicates that the second laser sensor 61 moves by a distance of one grid width. Therefore, the distance of the second laser sensor 61 moving along with the pull rod 51 can be accurately fed back according to the times of the shielding and the communication of the correlation light path.

When solid and liquid seasonings are discharged, the material box moves for a certain distance to correspondingly discharge the solid seasonings in parts by weight in the material groove, and the piston moves for a certain distance to correspondingly discharge the liquid seasonings in parts by volume. Therefore, according to the required amount of the seasoning, the displacement of the pull rod 51 required to move can be correspondingly obtained. As described above, the second laser sensor 61 and the grid ruler 64 can be used for precisely controlling the moving distance of the pull rod 51, so that the moving distance of the pull rod 51 can be controlled by the second laser sensor 61 and the grid ruler 64, thereby realizing precise discharging of solid and liquid seasonings and further meeting the requirement of actual dish cooking.

The material box 320 and the piston 413 are pushed correspondingly by the forward movement of the pull rod 51 to discharge materials, and the piston is pulled correspondingly by the backward movement of the pull rod 51 to suck materials. Therefore, the initial position of the pull rod 51 is needed to be calibrated as the origin, and the two extreme positions of the movement of the pull rod 51 are simultaneously calibrated, so that the magazine 320 and the piston 413 can move within a certain range.

In order to achieve the above purpose, the position sensing switches 63 are divided into front, middle and rear positions along the moving direction of the pull rod 51 and are respectively arranged on one side of the pull rod 51, the middle position sensing switch 63 corresponds to the original position of the pull rod 51, the front position sensing switch 63 corresponds to the limit position of the forward movement of the pull rod 51, and the rear position sensing switch 63 corresponds to the limit position of the backward movement of the pull rod 51.

The blocking piece 62 is used for being matched with the position sensing switch 63, and when the blocking piece 62 and the position sensing switch 63 are arranged oppositely, the position sensing switch 63 can sense the position of the blocking piece 62. Accordingly, the flap 62 is fixed to the slider 59 on which the pull rod 51 is located, so that the flap 62 can move synchronously with the advance or retreat of the pull rod 51. Meanwhile, when the pull rod 51 is located at the initial position, the blocking piece 62 is arranged opposite to the middle position sensing switch 63.

When the solid seasoning is discharged, whether the pull rod 51 is located at the initial position is judged through the middle position induction switch 63, and when the pull rod 51 is located at the initial position, the stepping motor 53 drives the material box to advance through the pull rod 51. According to the gram number of the needed solid seasoning, the accurate discharge of the solid seasoning is realized under the accurate control of the second laser sensor 61 and the grating ruler 64. After the discharging is completed, the stepping motor 53 drives the pull rod 51 to return to the initial position again.

In addition, during the process of the solid seasoning coming out, if the blocking piece 62 moves along with the pull rod 51 to be opposite to the front position sensing switch 63, indicating that the pull rod 51 has moved to the extreme position, the front position sensing switch 63 can feed back a signal to stop the operation of the stepping motor 53.

When the liquid seasoning is discharged, it is first determined whether the pull rod 51 is located at the initial position by the intermediate position sensing switch 63. When the pull rod 51 is located at the initial position, the stepping motor 53 drives the piston to retreat through the pull rod 51 under the precise control of the second laser sensor 61 and the grid ruler 64 according to the amount of the required liquid seasoning, so as to realize the suction of the liquid seasoning. Then, the stepping motor 53 drives the piston to advance through the pull rod 51 to discharge the liquid flavoring, and meanwhile, the pull rod 51 returns to the initial position again.

In addition, during the process of the liquid seasoning, if the blocking piece 62 moves along with the pull rod 51 to be opposite to the position sensing switch 63 at the front and rear part, which indicates that the pull rod 51 has moved to the extreme position, the position sensing switch 63 at the rear part can feed back a signal to stop the operation of the stepping motor 53.

In conclusion, the seasoning quantitative discharge control device provided by the utility model drives the pull rod to move forward or backward through the power structure formed by the stepping motor, the speed reducer, the transmission wheel and the transmission belt, and the pull rod further drives the material box and the piston to act, so that the automatic discharge of solid and liquid seasonings is realized, and the requirement of automatic cooking is met.
