[0103] The rotation limiting shell 61 is a cylindrical shell arranged horizontally along the axis, and the opposite side walls of the rotation limiting shell 61 are respectively provided with an upper opening 611 and a lower opening 612. The two ends of the cylindrical shell are fixed with the closing plates 613, and the upper edge of the closing plate 613 is flush with the edge of the upper opening 611.

[0104] The quantitative vane part 62 includes a positioning block 621 and a plurality of vanes 622 fixed in a ring shape on the outer side of the positioning block 621. The positioning block 621 is coaxially arranged with the cylindrical shell, and the middle part of the positioning block 621 is rotationally connected with one of the closing plates 613. The plurality of vanes 622 are fixed on the part of the positioning block 621 inside the cylindrical shell, and the axis of the positioning block 621 is provided with a rotation hole 6211.

[0105] The lead screw 63 is rotationally connected at one end in the rotation hole 6211, and the other end of the lead screw 63 extends to the central space of the plurality of vanes 622. The rod body of the lead screw 63 is threadedly connected with the adjusting nut 65, and the adjusting nut 65 is connected with the positioning block 621 through the first telescopic sleeve 66. The first telescopic sleeve 66 closes the opening of the adjacent vane 622 corresponding to the lead screw 63.

[0106] The baffle 64 is sleeved on the outer side of the plurality of vanes 622, and is provided with a sliding notch 641 for avoiding the plurality of vanes 622. The sliding notch 641 is slidably connected with the plurality of vanes 622, and the middle part of the baffle 64 is fixed with the adjusting nut 65.

[0107] In the embodiment, the discharge port 32 at the bottom of the sub-fan-shaped unit box 33 for containing solid seasoning is a square port, and the edge of the upper opening 611 of the rotation limiting shell 61 is fixedly connected with the square port.

[0108] In order to further optimize the above technical scheme, the second telescopic sleeve 67 is sleeved on the outer side of the plurality of vanes 622, and the two end edges of the second telescopic sleeve 67 are fixedly connected with the baffle 64 and the end of the plurality of vanes 622 away from the positioning block 621.

[0109] In the embodiment, the first telescopic sleeve 66 and the second telescopic sleeve 67 can adopt the structure of a bellows or a multi-stage telescopic sleeve.

[0110] In order to further optimize the above technical scheme, the part of the positioning block 621 outside the cylindrical shell is provided with a horizontal vane rotation slot 6212, the end of the lead screw 63 in the rotation hole 6211 is provided with a lead screw rotation slot 631, and the end faces of the lead screw rotation slot 631 and the vane rotation slot 6212 have an avoiding distance.

[0111] In order to further optimize the above technical solutions, the rotating hole 6211 has an annular limiting groove 6213, and the outer wall of the screw rod 63 has an annular limiting protrusion 632 embedded in the annular limiting groove 6213.

[0112] In order to further optimize the above technical solutions, one side edge of the upper opening 611 of the rotation limiting shell 61 has an auxiliary circular arc top 614 extending upwards along the arc of the rotation limiting shell 61, and the setting position of the auxiliary circular arc top 614 is located on the upper opening 611 edge on the rear side of the rotation direction of the blade 622.

[0113] In order to further optimize the above technical solutions, the adjacent blades 622 form a fan-shaped quantitative cavity 623, and in the static state, the upper fan-shaped quantitative cavity 623 corresponds to the upper opening 611, and the lower fan-shaped quantitative cavity 623 corresponds to the lower opening 612.

[0114] When quantitative adjustment is needed, the screw rod 63 is twisted, and at this time the positioning block 621 on the outer side of the screw rod 63 does not rotate, in order to meet this condition, the rotating friction between the positioning block 621 and the closing plate 613 can be increased, that is, a slight interference fit structure is provided. When the screw rod 63 is rotated, the baffle 64 cannot be rotated due to the limiting relationship of the baffle 64 and the blade 622, therefore, the adjusting nut 65 moves along the length direction of the screw rod 63, thereby adjusting the capacity of the fan-shaped quantitative cavity 623. When discharging is needed, the positioning block 621 is twisted, and the blade 622 is rotated, and the discharge is carried out from the lower opening 612.

[0115] In this embodiment, if the second telescopic sleeve 67 is provided as a three-stage cylindrical telescopic sleeve structure: the cylinder of each stage corresponds to a volume of 0.5g / cm 3 , so there are three layers in total, and two layers can be protruded, one layer can be compressed to a volume of 0.5g / cm 3 , and two layers are out, which can be compressed from the initial maximum volume of 1.5g / cm 3 , to a volume of 1g / cm 3 , to the minimum volume of 0.5g / cm 3 . Of course, through the precision of the screw thread of the screw rod 63 and the number of rotation of the adjusting nut 65, any volume between 1.5g / cm 3 and 0.5g / cm 3 can be adjusted. In addition, due to the existence of friction in reality, the three-layer structure is sequentially out of the ideal situation, and the above content is used as a reference for capacity adjustment. If the three layers act at the same time, the quantitative adjustment will not be affected, and the volume is fixed.

[0116] It can be seen that in the embodiment, three powers are required for driving, i.e. the discharging power source 41 and the adjusting power source 42; the discharging power source 41 includes a solid discharging power 411 for screwing the positioning block 621 and a liquid discharging power 412 for driving the negative pressure suction pump 7; the adjusting power source 42 is used for screwing the lead screw 63.

[0117] Further, the solid discharging power 411 and the liquid discharging power 412 can be coupled with any group of the positioning block 621 and the action end of the negative pressure suction pump 7 at the same time, and the adjusting power source 42 is coupled with the lead screw 63 by position switching with the solid discharging power 411.

[0118] Therefore, the setting angle of the solid discharging power 411 and the liquid discharging power 412 is the same as the angle of the discharging port 32 of the two sub-fan unit boxes 33.

[0119] In the embodiment, the adjustment of the lead screw 63 is limited to adjustment once according to the density of the solid seasoning at the initial time, and subsequent adjustment is not required, and only discharging control is required. After the density of the solid seasoning is determined each time, corresponding quantitative accuracy adjustment is performed. If the solid seasoning is always of one brand, only one adjustment is required. If the solid seasoning is replaced by a different brand, the density of the different brand is adjusted again.

[0120] According to the data of the laboratory of Beijing University of Civil Engineering and Architecture, the bulk density of different solid seasonings is between 0.7-1.1 g / cm 3 , the density of liquid seasoning is between 0.9-1.3 g / cm 3 , and the density of related seasonings is shown in Table 1.

[0121] Table 1 Seasoning density

[0122] Seasoning Density g / cm 3 ]] Haitian brand soy sauce 1.17 Haitian brand soy sauce 1.23 Shuita brand vinegar 1.07 Kitchen brand cooking wine 0.95 Zhongyan brand salt 1.07 Gufu brand white sugar 1.09 Tatao brand chicken essence 0.77 Lianhua brand monosodium glutamate 0.89 Shuangta brand cornstarch 1.05

[0127] In order to further optimize the above technical solution, the inclined surface of the wedge-shaped head 2611 is processed into an outward convex arc surface 2612.

[0128] Referring to the accompanying drawings, Figure 6 The outer circumferential wall surface of the upper driving disc 21 and the lower driving disc 22 is provided with an elastic marble 265, and the inner wall of the outer shell 1 is provided with a limiting groove 266 corresponding to the elastic marble 265.

[0129] In order to further optimize the above technical solution, the bidirectional driving mechanism 23 comprises a bidirectional driving motor 232, the housing of the bidirectional driving motor 232 is fixed to the inner wall of the outer shell 1, and the power output shaft of the bidirectional driving motor 232 is fixed with the driving gear 231.

[0130] In order to further optimize the above technical solutions, the number of the fan-shaped seasoning unit boxes 3 is the same as the number of the elastic wedge-shaped parts 26 arranged on the upper driving disc 21 and the lower driving disc 22, and the plurality of elastic wedge-shaped parts 26 correspond to the plurality of fan-shaped seasoning unit boxes 3 respectively.

[0131] Referring to the accompanying drawings Figure 19 and the accompanying drawings Figure 20 , the solid discharging power 411 includes a solid discharging motor 4111 and a solid discharging linear shaft 4112; the liquid discharging power 412 includes a liquid discharging vibration motor 4121 and a liquid discharging linear shaft 4122; the adjusting power source 42 includes an adjusting motor 421 and an adjusting linear shaft 422. It should be noted that in order to realize size adjustment, the adjusting motor 421 is a bidirectional motor, which can realize rotation in different directions.

[0132] In the embodiment, the bottom center of the upper driving disc 21 is fixed with a center shaft 211, the center of the lower driving disc 22 has a through hole 221 avoiding the center shaft 211, and the driving part 4 is installed at the bottom end of the center shaft 211. The bottom end of the center shaft 211 is rotationally connected with the fixed rod of the seasoning box linear telescopic rod 1331, and the bottom end of the center shaft 211 has three radially extending driving installation rods 2111, on which the solid discharging motor 4111, the liquid discharging vibration motor 4121 and the adjusting motor 421 are respectively installed; the power output end of the solid discharging motor 4111 is connected with the solid discharging linear shaft 4112, the power output end of the liquid discharging vibration motor 4121 is connected with the liquid discharging linear shaft 4122, and the power output end of the adjusting motor 421 is connected with the adjusting linear shaft 422. The setting angles of the three driving installation rods 2111 are shown in Figure 21 and Figure 22 , which can meet the coupling with the positions needing to be driven respectively in the process of rotation. In addition, the three driving installation rods 2111 need to avoid the upper and lower positions to prevent position interference.

[0133] It should be noted that the solid discharging linear shaft 4112 rotates 180° every time to discharge 1g, that is, 0.5g is set in each fan-shaped dosing cavity 623.

[0134] Referring to the accompanying drawings Figure 34 , the liquid inlet pipe 71 of the negative pressure suction pump 7 is connected with the discharging port, the liquid outlet pipe 72 is downward, the power end of the negative pressure suction pump 7 has a liquid outlet linear notch 73, after the liquid discharging linear shaft 4122 is inserted, the liquid discharging vibration motor 4121 discharges liquid by vibration. Each vibration will compress the volume of the dose, and the volume of the liquid discharging each time is calculated as 0.5cm 3 . 3At the same time, the density of the liquid seasoning in the system and the volume of the liquid seasoning required by the user are combined, and the required liquid volume is obtained according to the density formula ρ=m / V. The liquid discharge vibration motor 4121 is vibrated by dividing the required liquid volume by the volume of the gas compressed each time, and the required amount of liquid seasoning is obtained through system control.

[0135] In order to realize the detection of the amount of seasoning in the fan-shaped seasoning unit box 3, the embodiment further adds an ultrasonic sensor 27. A radial detection mounting rod 2112 is arranged on the upper part of the central shaft 211, that is, at a position between the upper driving disc 21 and the lower driving disc 22. The ultrasonic sensor 27 is mounted on the detection mounting rod 2112. The lower driving disc 22 is provided with a detection hole 223 corresponding to the fan-shaped seasoning unit box 3. The detection hole 223 can detect the depth of the seasoning in the fan-shaped seasoning unit box 3 when the fan-shaped seasoning unit box 3 rotates, and further judge whether the fan-shaped seasoning unit box 3 needs to be refilled.

[0136] The wires of the ultrasonic sensor 27 and the motors of the driving part 4 are connected to the circuit board through the inside of the central shaft 211.

[0137] After each seasoning is finished, the lower driving disc 22 rotates to reset, or the system retains the position information of this time to provide a standard for the next start.

[0138] In the embodiment, the intelligent control layer 11 further includes a display screen 111 for displaying an interface and a touch panel 112 for use by an operator.

[0139] In the embodiment, the display screen 111 is used for displaying information, and the touch panel 112 is used for interactive operation by an operator. The circuit board is used for integrating various function control modules, mainly including:

[0140] Central processing unit (CPU): The central processing unit is used for receiving signals and outputting control signals.

[0141] Information storage module: used for storing information of dishes, that is, which seasonings are required for a certain dish, and corresponding seasoning usage according to different number of diners, that is, the standby amount of the dish corresponds to the corresponding seasoning usage. The information storage module can be the information content provided by the factory, or can be input by the user through the interaction of the touch panel 112 and the display screen 111 according to the user's use demand.

[0142] When the operator selects the dish to be made by touching the touchpad 112, the information storage module transmits the corresponding dish information to the central processor, the central processor controls the rotation of the bidirectional drive motor 232, and the bidirectional drive motor 232 controls the rotation of the lower drive disc 22. In this embodiment, the number of rotations of the drive gear 231 is set to correspond to the corresponding position, for example, 5 rotations of the drive gear 231 is 72°, that is, the standard position of each sector-shaped seasoning unit box 3. In this way, by rotating the drive gear 231, the corresponding sector-shaped seasoning unit box 3 that needs to be discharged is adjusted to align with the receiving box 5, and then the corresponding solid discharge motor 4111 and liquid discharge vibration motor 4121 are controlled to start discharging. The solid discharge motor 4111 has a solid discharge linear shaft 4112 that rotates different number of turns to correspond to different grams, and the liquid discharge vibration motor 4121 vibrates different number of times to correspond to different capacities.

[0143] After discharging is completed, the bidirectional drive motor 232 controls the rotation of the lower drive disc 22 to reset. A corresponding infrared sensing element can be provided inside to facilitate resetting. In this embodiment, the information storage module records the position through information input, and finally realizes resetting. The infrared sensing element is a conventional structure, that is, it can be provided between the non-rotating body and the rotating body. In this utility model, it can be provided on any rotating structure inside the shell body 1, which is a conventional structure feature and will not be described here.

[0144] When the seasoning discharging is completed, the receiving box linear track ejection mechanism 141 is started to drive the receiving box ejection door 142 and the receiving box 5 to pop out, which can be taken by the operator. After taking and putting back, the receiving box linear track ejection mechanism 141 drives the receiving box ejection door 142 and the receiving box 5 to retract.

[0145] The information storage module provided in this embodiment is also used to store the seasoning density information described above. When different seasonings are switched, the central processor controls the rotation of the bidirectional drive motor 232, and the bidirectional drive motor 232 controls the rotation of the upper drive disc 21. That is, the central shaft 211 is driven to rotate, and the capacity of the sector-shaped metering cavity 623 is adjusted by adjusting the motor 421 to screw the lead screw 63. It should be noted that before the first time of loading and before the solid and liquid discharging, the solid discharge motor 4111 of the solid discharge part needs to be rotated by 180°, and the liquid discharge vibration motor 4121 needs to be vibrated three times. The operator needs to judge whether the machine discharges normally by whether there is seasoning for compensation in the receiving box 5, and finally dispose of it.

[0146] During the rotation of the lower drive disc 22, the ultrasonic sensor 27 on the mounting rod 2112 detects the depth in the sector-shaped seasoning unit box 3, and then judges whether the internal seasoning is sufficient. If not, it is fed back to the central processor to alarm.

[0147] When the seasoning needs to be added, the seasoning box linear track pop-up mechanism 133 drives the fan-shaped seasoning unit box pop-up door 132 and the fan-shaped seasoning unit box 3 that needs to be supplemented to pop up, and the adding operation can be performed.

[0148] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same or similar parts between various embodiments can be referred to each other.

[0149] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application.
