It should be noted that the above arrangement is such that the lower end 255 serves as the lateral axis of the dosing blade 251 so that the dosing blade 251 can pivot downward about the lateral axis.

The first food adding device 20 works as follows: s1, after the user selects the dish to be purchased on the user operation panel, the bowl falling to the bowl falling station 2 is pushed to the bowl placing plate 242 of the rotating frame 24 by the bowl pushing piece 50 and is also positioned right below the quantitative blanking device 25, and then the controller controls the bowl pushing piece 50 to retreat so as to avoid blocking the bowl and prevent the bowl from rotating together with the rotating frame 24; s2, the controller controls the frame motor 240 to start, the frame motor 240 drives the rotating frame 24 to rotate, so that the quantitative pallet 251 moves to the bottleneck at the lower end of a specific food storage bottle 23 along with the rotation of the rotating frame 24, and the controller turns off the frame motor 240; s3, correspondingly, the controller also controls the turntable motor 211 to start, the turntable motor 211 drives the rotation shaft 213 to rotate so as to drive the rotation disc 214 to rotate, so that the capping motor 210 moves to the transmission gears 230 of the food storage bottle 23 (it should be explained that the capping motor 210 will idle the transmission gears 230 to a certain extent when passing through other transmission gears 230), and then the controller stops the turntable motor 211; s4, under a normal state, the quantitative supporting plate 251 blocks the through hole 244; the controller controls the connecting rod motor 250 to drive the quantitative supporting plate 251 to descend so as to form the quantitative discharging space, and controls the cap screwing motor 210 to drive the transmission gear 230 to drive the threaded rod 234 to rotate, the threaded rod 234 stirs the food in the food tube to be loose before blanking (or stirs the food in the food storage bottle while blanking), then the food in the food tube can fall into the quantitative discharging space under the action of self gravity, and then the controller stops the cap screwing motor 210 and the connecting rod motor 250; s5, the controller starts the rack motor 240 again, the rack motor 240 drives the rotating rack 24 to rotate so as to drive the quantitative pallet 251 to move to a position not corresponding to the discharge hole of the food storage bottle 23 (the sharp edge 243 is used to cut off the food between the quantitative discharge space and the food storage bottle 23 in the process), no food falls into the quantitative discharge space after the quantitative pallet 251 is moved away, and the controller stops the rack motor 240; s6, the controller starts the connecting rod motor 250 again to enable the quantitative supporting plate 251 to turn 90 degrees downwards, food in the quantitative discharging space falls into a bowl of the bowl placing plate 242, and then the connecting rod motor 250 rotates reversely to drive the quantitative supporting plate 251 to reset to be horizontal and move upwards until the quantitative supporting plate 251 is embedded in a through hole 244 of the bottle bottom supporting plate 241; since the length of the vertical groove 258 is fixed, the descending distance of the quantitative support plate 251 is fixed, and the capacity of the quantitative discharging space is also fixed. S7, the controller starts the rack motor 240 to drive the rotating rack 24 to rotate, the bowl is driven to rotate back to the food adding station 3, and then the controller stops the rack motor 240 and controls the bowl pushing piece 50 to push the bowl located at the food adding station 3 to the sauce adding station 4. It should be noted that the rotating frame 24 in this embodiment is a moving frame that rotates horizontally, but instead, it may move horizontally and linearly, and the food storage bottles are pressed on the end surface of the moving frame in a horizontal and linear arrangement.

A sauce adding device 30 (prior art) adds sauce to the bowl positioned at the sauce adding station 4 under the control of the controller, wherein the sauce comprises sauce and powdery seasonings; after the controller controls the sauce adding device 30 to add sauce to the bowl, the controller controls the bowl pushing part 50 to push the bowl positioned at the food adding station 3 to the second food adding station 3, the second food adding device 20 and the first food adding device 20 are completely the same in structure and working principle, the second food adding device 20 adds cold dishes selected by a user on a user operation panel into the bowl positioned at the second food adding station 3, and then the controller controls the bowl pushing part 50 to push the bowl positioned at the second food adding station 3 to the bowl cover falling station 5. It should be noted that the reason for providing two identical food adding devices 20 is: there are various kinds of cold dishes, if the food storage bottles 23 containing different cold dishes are all installed on one food adding device 20, the diameter of the food adding device 20 is large (as can be seen from the operation of the food adding device 20 described above, the food storage bottles 23 must be arranged in the circumferential direction of the food adding device 20, and thus the diameter of the food adding device 20 is large as the number of the food storage bottles 23 is large), so that the volume difference between the food adding device 20 and other devices (such as the bowl dropping device 10 and the sauce adding device 30) in the cold dish vending machine is too large, which results in too large floor space and not compact internal structure of the cold dish vending machine.

As shown in fig. 4, the bowl is pushed from the second food adding station 3 to the bowl cover dropping station 5 by the bowl pushing member 50 and then supported by the dish discharging bracket 70, and the controller controls the stirring device 60 to stir the cold dish contained in the bowl located at the bowl cover dropping station 5.
