1-7, since the lunch box vending machine 100 equipped with the pushing device of the utility model box lunch vending machine has a unique push rod 31, a turntable 60 and a storage box 20 fixed thereon, when in use, The buyer selects and purchases by operating the human-computer interaction device 300. Under the control of the human-computer interaction device 300, the turntable drive mechanism 80 drives the turntable 60 to rotate, and the rotation of the turntable 60 drives the storage box 20 on it to rotate synchronously. When the storage box 200 of the lunch box type selected by the buyer was facing the push rod 31, the rotation of the turntable 60 was stopped, and now the push mechanism 30 drove the push rod 31 to move toward the discharge port 21 (i.e. stretch out), so that the push rod 31 was pushed forward. The rod 31 will gradually approach the lunch box 200 at the bottom of the storage box 20 facing it, and along with the continuous driving of the propulsion mechanism 30, the pushing rod 31 will penetrate into the discharge port 21 of the storage box 20 facing it and connect with the The lunch box 200 conflicts, and under the continued driving of the propulsion mechanism 30, the push rod 31 pushes the box lunch located in the discharge port 21 to the receiving platform 40, so that the buyer can directly take away the box lunch pushed to the receiving platform 40 , or the lunch box on the receiving platform is transmitted to the next process (such as heating, packing, etc.) by the transmission mechanism; The opposite direction of the feed opening 21 makes a horizontal linear motion (i.e. shrinking motion), and the push rod 31 will shrink and withdraw from the discharge opening 21, waiting for the next push to buy the lunch box purchased by the buyer; it can be seen that the whole box lunch purchase process is simple, fast and convenient. There is no need for workers to take the operation, the degree of automation is high, it is clean and hygienic, and the sales efficiency is high; at the same time, due to the use of multiple storage boxes 20 for refrigerated storage of lunch boxes, and each storage box 20 can store multiple lunch boxes, and different storage boxes 20. It can also store different lunch boxes. The storage capacity of the box lunches is large, and all the lunch boxes are refrigerated and kept fresh through the refrigeration device to ensure that the quality of the box lunches is not affected; Different types of lunch boxes to meet the needs of people with different tastes, and when selecting different types of box lunches, no manual operation is required, which is clean and hygienic, and improves sales efficiency, bringing more convenience to people's travel and dining.

As shown in Figures 2-7, preferably, the box lunch vending machine 100 also includes two support mechanisms 90, and the support mechanism 90 includes a second motor 91, a support rod 92, a support block 93, and a first match with each other. Two ball screw rods 94 and a second ball nut 95, the second motor 91 is fixed on the body 10, the second ball nut 95 is fixed on a vertical support rod 92, and the support block 93 Connected to the support rod 92, the output shaft of the second motor 91 is connected to the lower end of the second ball screw 94, and the upper end of the second ball screw 94 passes through the second ball nut 95, The turntable 60 is provided with a through slot 62 for the support block 93 to pass through; preferably, the upper end of the support block 93 is in a concave structure, and the concave structure forms an avoidance channel for the push rod 31 to pass through. 931 (as shown in Figure 6); during work, the rotation of the second motor 91 drives the rotation of the second ball screw 94, because the second ball screw 94 and the second ball nut 95 are mutually matched, and the second ball The nut 95 is fixed on the support rod 92 that is vertically arranged, so the rotation of the second ball screw 94 will drive the support rod 92 to perform linear telescopic movement in the vertical direction through the second ball screw 95, and the support rod 92 will move in a straight line in the vertical direction. The straight-line telescopic movement in the vertical direction will synchronously drive the support block 93 fixed on it to perform linear telescopic movement in the vertical direction; similarly, when the second motor 91 rotates clockwise, the support block 93 will move towards the direction of the through groove 62 Make a straight line motion in the vertical direction (that is: when the second motor 91 rotates clockwise, the support block 93 is stretched out, that is, rises), so that when the second motor 91 rotates counterclockwise, the support block 93 moves toward the through groove 62 The opposite direction of the motor makes a vertical linear motion (that is, when the second motor 91 rotates counterclockwise, the support block 93 makes a shrinking motion, that is, a downward motion), so the rotation of the second motor 91 will drive the support block 93 in the vertical direction. direction, and since the turntable 60 is provided with a through groove 62 for the upper end of the support block 93 to pass through, the support block 93 of the two support mechanisms can The gradual rise supports the bottom of the box lunch above the box lunch being pushed; specifically, in order to make the push rod 31 push the box lunch in the discharge port 21 further steadily and reliably to the receiving platform 40, when the push rod 31 When the lunch box 200 in the discharge port 21 is pushed out less than half, the upper end of the support block 93 of the support mechanism 90 on the right is driven by the second motor 91 to rise upwards and pass through the top of the through groove 62 of the turntable 60 Live at the bottom of the box lunch above the box lunch in the discharge port 21, and as the push rod 31 continues to push the box lunch, when the box meal is pushed out of the discharge port 21 for more than half, the upper end of the support block 93 of the support mechanism 90 on the left Driven by the second motor 91, it rises upwards and passes through the through groove 62 of the rotating disk 60 to withstand the bottom of the box lunch on the box lunch in the discharge port 21. At this time, it is stacked on the box lunch being pushed by the push rod 31. The weight of all lunch boxes is divided by two Supported by the support block 93 of the support mechanism 90, so that the lunch box being pushed by the push rod 31 can be pushed out of the discharge port 21 and sent to the receiving platform 40 more smoothly and reliably; when the lunch box 200 is pushed by the push rod 31 When going out the discharge port 21, two support blocks 93 continue to support all the lunch boxes on the pushed lunch box, and along with the push rod 31 gradually withdraws from the discharge port 21, when the push rod 31 withdraws from the discharge port 21 completely, the two The support block 93 of the support mechanism 90 descends synchronously under the action of the second motor 91 to exit the through groove 62 of the turntable 60, and the lunch box carried on the support block 93 is carried on the turntable 60 by the decline of the support block 93, thereby entering Waiting to push the state of the lunch box purchased by the buyer next time (as shown in FIG. 1 ), therefore, by the two supporting mechanisms 90, other lunch boxes in the storage box 20 can be stably refrigerated during the sale of the lunch box. The support mechanism 90 of the present utility model realizes the linear telescopic movement of the support block 93 in the vertical direction through the matching of the second ball screw 94 and the second ball nut 95, which greatly improves the pushing accuracy of the box lunch 200 and ensures that the box lunch Can be pushed to the receiving station 40 accurately. It should be noted that, as shown in FIG. 7, the second ball screw 94 has the same structure as the first ball screw 33 shown in FIG. 7, and the second ball nut 95 has the same structure as the first ball nut 34 shown in FIG. . The difference between the above two lies only in the installation orientation, and those skilled in the art can interchange the two without any creative work under the premise of the technical solution provided by the utility model, and no further details are given here.
