Each of the three feeding components 11 has a station 111 for placing containers. The structure of the feeding component 11 has been disclosed and will not be explained in detail here. Its structure is the same as that of the bowl feeding mechanism in the automatic food adding and bowl recycling device in the background art 2023207793263.

[0040] refer to Figure 2 and Figure 3 As shown, two container receiving drivers 31 are fixedly installed on one side of the frame 1.

The two telescopic actuators 243 are respectively fixedly installed at opposite corners on the upper side of the flip frame plate 242. Two blocking actuators 244 are fixedly installed on the upper side of the flip frame plate 242. The flip frame plate 242 is provided with a through groove 2421. The two blocking actuators 244 are evenly arranged around the through groove 2421. When the two telescopic actuators 243 are activated at the same time, they drive the flip base plate 241 to move away from the flip frame plate 242, increasing the distance between them until the thickness of the container is reached. The output ends of the two blocking actuators 244 extend outward to above the through groove 2421, blocking the container.

[0046] Among them, the telescopic starter 243 is a cylinder.

[0047] Among them, the blocking actuator 244 is a cylinder.

[0048] In this embodiment, after the blocking driver 244 blocks the container, the mounting block 23 drives the flipping frame plate 242 to rotate, and the flipping bottom plate 241 rotates together with the flipping frame plate 242 until the flipping bottom plate 241 is above the flipping frame plate 242, so that the container opening faces downward, and the material in the container falls downward.

[0049] refer to Figure 6 and Figure 7 As shown, a pusher 41 is fixedly installed on one side of the frame 1. A pusher plate 42 is fixedly installed on the output end of the pusher 41. The pusher plate 42 is located on the opposite side of the mounting plate 21 inside the frame 1. The pusher plate 42 has a slot 421 for the container on the side facing the mounting plate 21. The pusher 41 can drive the pusher plate 42 to move towards the mounting plate 21, thereby pushing the container on the receiving plate 32 to move horizontally until it is located in the through slot 2421 on the flip frame plate 242.

[0050] Among them, the push container driver 41 is a linear motor.

[0051] It should be noted that the height of the push plate 42 is greater than the height of the flip frame plate 242, which can push the container on the receiving container plate 32 to move.

[0052] refer to Figure 1 and Figure 8 As shown, a fixed plate 12 is provided at the bottom of the frame 1. A sliding groove 122 is provided on the fixed plate 12. A translation driver 511 is fixedly installed on the lower side of the fixed plate 12. A translation plate 513 is fixedly installed on the upper side of the fixed plate 12. One end of a translation rod 512 is fixedly connected to the output end of the translation driver 511. The other end of the translation rod 512 passes through the sliding groove 122 and is fixedly connected to the translation plate 513. The translation rod 512 is slidably connected in the sliding groove 122.

[0053] Among them, the translation driver 511 drives the translation rod 512 to slide in the slide groove 122, and the translation rod 512 drives the translation plate 513 to move.

[0054] Among them, the translation driver 511 is a motor lead screw drive, and a sliding block is provided on the lead screw. The sliding block is the output end of the translation driver 511, and the translation rod 512 is fixedly connected to the sliding block.

[0055] refer to Figure 3 As shown, a push-out driver 521 is fixedly installed on the translation plate 513, a push-out limiting slide 522 is fixedly installed on the translation plate 513, a push-out plate 523 is slidably connected to the push-out limiting slide 522, the push-out plate 523 is fixedly connected to the output end of the push-out driver 521, and the output end of the push-out driver 521 drives the push-out plate 523 to move.

[0056] Among them, the driver 521 is a linear motor or a motor screw drive, preferably a linear motor.

[0057] refer to Figure 1 As shown, a pull-out driver 531 is fixedly installed on the ejector plate 523, and a pull-out component 532 is fixedly connected to the output end of the pull-out driver 531. The pull-out component 532 is provided with a locking platform 5321, and the pull-out driver 531 drives the pull-out component 532 to move.

[0058] Among them, the pull-out driver 531 is a cylinder.

[0059] refer to Figure 1As shown, a receiving box 6 is fixedly installed on the ejector plate 523. The bottom of the receiving box 6 is open, and a pull plate 61 is slidably connected to the bottom of the receiving box 6. The pull plate 61 is used to open and close the bottom opening of the receiving box 6. One end of the pull plate 61 is provided with a pull table 611. The pull table 611 is provided with a latch 612. The latch 612 is engaged with the latch 5321. The pull-out part 532 drives the pull plate 61 to move through the latch 5321, thereby opening or closing the bottom opening of the receiving box 6.

[0060] It should be noted that the bottom opening of the receiving box 6 is offset from the push plate 523, so that the push plate 523 can drive the receiving box 6 to move to the outside of the frame 1, so that the bottom opening of the receiving box 6 is located on the outside of the frame 1, thereby transferring the material in the receiving box 6 from the outside of the frame 1.

[0061] refer to Figure 1 As shown, the fixed plate 12 is located below the flip frame plate 242 and has a container outlet 121. The containers on the flip frame plate 242 fall downwards and fall into the container collection point from the container outlet 121.

[0062] The working principle of this utility model is as follows:

[0063] A single container is dropped downwards via the feeding assembly 11;

[0064] The container driver 31 pushes the container receiving plate 32 upward until it reaches the container's landing point, smoothly catching the container. Then, the container driver 31 pushes the container receiving plate 32 downward until it is on the same horizontal plane as the flipping frame plate 242 before flipping. When the container receiving plate 32 is far away from the flipping frame plate 242, all the container receiving plates 32 in the middle are pushed by the container driver 31 so that all the container receiving plates 32 are on the same horizontal plane as the flipping frame plate 242 before flipping.

[0065] The pusher 41 drives the pusher 42 to move toward the mounting plate 21, and its direction of movement is perpendicular to the mounting plate 21, pushing the container on the receiving plate 32 to move in the direction of the mounting plate 21 until it is located in the through groove 2421 on the flip frame plate 242.

[0066] When the container is located in the through groove 2421, the two telescopic actuators 243 are activated simultaneously, causing the flip base plate 241 to move away from the flip frame plate 242, increasing the distance between them until the thickness of the container is reached. The output ends of the two blocking actuators 244 extend outward to block the container above the through groove 2421, so that the container is stuck between the flip base plate 241 and the flip frame plate 242 and located in the through groove 2421.

[0067] After the blocking driver 244 blocks the container, the flipping driver 22 drives the mounting block 23 to rotate, the mounting block 23 drives the flipping frame plate 242 to rotate, and the flipping bottom plate 241 rotates together with the flipping frame plate 242 until the flipping bottom plate 241 is above the flipping frame plate 242, so that the container opening faces downward, and the material in the container falls downward.

[0068] The translation driver 511 drives the translation rod 512 to slide in the slide 122. The translation rod 512 drives the translation plate 513 to move. The translation plate 513 drives the receiving box 6 to move until it is directly below the flip frame plate 242, waiting for the material in the container to fall into the receiving box 6.

[0069] When the material falls into the receiving box 6, the translation driver 511 drives the translation rod 512 to slide in the slide groove 122. The translation rod 512 drives the translation plate 513 to move. The translation plate 513 drives the receiving box 6 to move away from the bottom of the flip frame plate 242. The output end of the push driver 521 drives the push plate 523 to move out of the frame 1 until the bottom opening of the receiving box 6 is located outside the frame 1.

[0070] The pull-out driver 531 drives the pull-out piece 532 to move, and the pull-out piece 532 pulls the pull plate 61 to move through the clamp 5321, thereby opening the bottom opening of the receiving box 6 and dropping the material in the receiving box 6 into the material receiving device.

[0071] When the flipping bottom plate 241 is above the flipping frame plate 242 and the material falls into the receiving box 6, after the receiving box 6 moves away from below the flipping frame plate 242, the output ends of the two blocking drivers 244 retract inward until they move away from above the through groove 2421, so that the container is unobstructed and falls downward, falling from the container outlet 121 into the container collection point.

[0072] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
