[0038] Reference Figures 1-9 One embodiment of this utility model provides an automatic vending machine shelf that can accommodate bowls of different sizes.

[0039] This utility model provides a vending machine shelf that can accommodate bowls of different sizes, as illustrated in the embodiments, including a base plate 1.

[0040] A limiting mechanism is installed on the base plate 1. The limiting mechanism limits the goods on the base plate 1 through the side baffle 201, the second mounting plate 202 and the limiting plate 302. A conveying mechanism is installed on the base plate 1. The conveying mechanism conveys the goods on the base plate 1 through the conveyor belt 506. The limiting mechanism includes a first mounting plate 2, a side baffle 201, a second mounting plate 202, a third mounting plate 3, a connecting plate 301 and a limiting plate 302. The side baffle 201 is integrally formed on both sides of the first mounting plate 2. The second mounting plate 202 is welded and fixed to one side of the side baffle 201. The third mounting plate 3 is installed on both sides of the top of the base plate 1. The connecting plate 301 is integrally formed on one side of the third mounting plate 3. The limiting plate 302 is integrally formed on one side of the connecting plate 301. The first mounting plate 2 is located at the middle of the top of the base plate 1.

[0041] In this embodiment, a limiting mechanism is used. The side baffle 201 between the first mounting plate 2 and the second mounting plate 202 is installed at an angle, forming a trapezoid between the two mounting plates. The size of the first mounting plate 2 is smaller than that of the second mounting plate 202. The third mounting plate 3, the connecting plate 301, and the limiting plate 302 form a Z-shaped plate. When fixing large bowl-shaped goods, the first mounting plate 2 is located at the top, the second mounting plate 202 is located at the bottom, and the limiting plate 302 is installed away from the center of the bottom plate 1, thus limiting the movement. With the increased space between plate 302 and side baffle 201, when fixing small bowl-shaped goods, the third mounting plate 3 is flipped and reinstalled. At this time, the limiting plate 302 is close to the center of the bottom plate 1. The first mounting plate 2 and the second mounting plate 202 are flipped so that the first mounting plate 2 is at the bottom and the second mounting plate 202 is at the top. This makes the space between the limiting plate 302 and the side baffle 201 smaller, which is convenient for manual adjustment to make the installation space between the limiting plate 302 and the side baffle 201 easier to store two bowl-shaped goods of different sizes.

[0042] In this example, the top of the base plate 1 is divided into two storage channels by the first mounting plate 2, the third mounting plate 3 and the side baffle 201. The limiting plate 302 blocks the other side of the storage channel, and each storage channel is equipped with a conveying mechanism.

[0043] Optionally, the first mounting plate 2 has a plurality of first mounting holes 204, the second mounting plate 202 has a plurality of second mounting holes 205, and the base plate 1 has a plurality of first threaded holes 206 and second threaded holes 207. The first mounting holes 204 and the first threaded holes 206 are positioned corresponding to each other, and the second mounting holes 205 and the second threaded holes 207 are positioned corresponding to each other. Both the first mounting plate 2 and the second mounting plate 202 can be fixedly mounted on the top of the base plate 1 by screws.

[0044] The second mounting plate 202 is U-shaped. Several reinforcing plates 203 are welded and fixed to the inner ring of the second mounting plate 202. The reinforcing plates 203 can be made of stainless steel. The reinforcing plates 203 support the side baffles 201 on both sides of the second mounting plate 202.

[0045] The third mounting plate 3 has several third mounting holes 303 on one side, and the screws that fix the third mounting plate 3 are installed in the third mounting holes 303.

[0046] In one embodiment, the conveying mechanism includes two first mounting frames 4, a first roller 402, a mounting shaft 403, a first insertion frame 404, a support plate 405, a second mounting frame 5, a second insertion frame 501, a heat dissipation mounting cylinder 503, a motor 504, a second roller 505, and a conveyor belt 506. The first mounting frames 4 are mounted on the top of the base plate 1. The first roller 402 is fixedly mounted on the outer wall of the mounting shaft 403. The mounting shaft 403 is rotatably mounted on the inner wall of the first mounting frame 4. The first insertion frame 404 is fixedly mounted on one side of the first mounting frame 4. The support plate 405 is mounted on one side of the first insertion frame 404. 05 engages with the first insertion frame 404, the second insertion frame 501 is fixedly installed on one side of the second mounting frame 5, the second insertion frame 501 is installed on one end of the support plate 405, the second insertion frame 501 engages with one end of the support plate 405, the heat dissipation mounting cylinder 503 is fixedly installed on one side of the inner wall of the second mounting frame 5, the motor 504 is fixedly installed on the inner wall of the heat dissipation mounting cylinder 503, one end of the second roller 505 is rotatably installed on the other side of the inner wall of the second mounting frame 5, the output end of the motor 504 is fixedly installed on one end of the inner wall of the second roller 505, and the conveyor belt 506 is installed on the outer wall of the first roller 402 and the second roller 505.

[0047] In this example, a bearing is provided at the connection between the mounting shaft 403 and the inner wall of the first mounting frame 4, allowing the mounting shaft 403 to rotate more smoothly; the support plate 405 is located on the inner ring of the conveyor belt 506, providing support for the top of the conveyor belt 506; the heat dissipation mounting cylinder 503 can be made of copper; the motor 504 is fixedly mounted on the heat dissipation mounting cylinder 503 with screws; and silicone grease can be filled between the outer wall of the motor 504 and the inner wall of the heat dissipation mounting cylinder 503 to fill the gap between them. The heat dissipation mounting cylinder 503 can conduct heat from the outer shell of the motor 504, increasing the heat dissipation effect of the motor 504. Furthermore, the motor 504 is designed to be hidden inside the second roller 505, which is more aesthetically pleasing and saves installation space compared to placing the motor 504 outside the second mounting frame 5.

[0048] In this example, motor 504 can be a servo motor, and motor 504 is connected to an external power supply in the prior art via wires.

[0049] In this example, the motor 504 starts and drives the second roller 505 to rotate, thereby driving the conveyor belt 506 to move and moving the bowl-shaped goods on it.

[0050] In one embodiment, a plurality of locking plates 401 are fixedly installed at the bottom of the first mounting frame 4, and a plurality of locking holes 103 are opened at the bottom of the base plate 1. The locking plates 401 are locked with the corresponding locking holes 103. A third threaded hole is opened at the bottom of the first mounting frame 4, and a fixing hole 104 is opened at the bottom of the base plate 1. The fixing hole 104 is positioned corresponding to the third threaded hole. A plurality of fixing posts 507 are fixedly installed on one side of the second mounting frame 5, and a fixing plate 105 is fixedly installed on one side of the base plate 1. The fixing plate 105 is provided with locking holes, and the fixing posts 507 are locked with the corresponding locking holes.

[0051] In this example, when installing the first mounting frame 4 and the second mounting frame 5, the first mounting frame 4 and the second mounting frame 5 are connected together by the support plate 405. The fixing post 507 on one side of the second mounting frame 5 is inserted into the corresponding engagement hole on the fixing plate 105, and the first mounting frame 4 on the other side is pressed down so that the locking plate 401 at the bottom of the first mounting frame 4 engages with the corresponding engagement hole 103. The first mounting frame 4 is further fixed by screws, so that the first mounting frame 4 and the second mounting frame 5 can be fixed to the base plate 1 more quickly, which facilitates the assembly and disassembly of the first mounting frame 4 and the second mounting frame 5.

[0052] In this example, the pallet 401 can be a feeding plate, and a triangular buckle can be provided at one end of the pallet 401. The buckle passes through the corresponding snap-fit ​​hole 103 and is snapped at the bottom of the base plate 1.

[0053] In this example, the first plug-in frame 404 and the second plug-in frame 501 can be fixed to both ends of the support plate 405 with screws.

[0054] In this example, several snap-fit ​​frames 101 are fixedly installed on the bottom of the base plate 1, and side plates 102 are fixedly installed on both sides of the base plate 1 by screws. The base plate 1 is set on the upper and lower partitions inside the vending machine cabinet. Several protrusions can be set on the partitions, and the snap-fit ​​frames 101 at the bottom of the base plate 1 snap onto the corresponding protrusions on the partitions.

[0055] In this example, the inner walls of the second mounting frame 5 are integrally formed with fixed cylinders 508 on both sides. The inner walls of the fixed cylinders 508 are rotatably mounted with limiting posts 509. The limiting posts 509 are located on one side of the outer wall of the conveyor belt 506. The bottom of the second insertion frame 501 is provided with a through hole. The conveyor belt 506 passes through the through hole at the bottom of the second insertion frame 501. The limiting posts 509 press the surface of the conveyor belt 506 so that the conveyor belt 506 can be tightly attached to the second roller 505.

[0056] Note: The first mounting plate 2 and the second mounting plate 202 can be installed by flipping up and down on the top of the base plate 1, and the third mounting plate 3 can be installed by flipping left and right on one side of the top of the base plate 1. By manually adjusting the installation of the first mounting plate 2, the second mounting plate 202 and the third mounting plate 3, the storage space between the limiting plate 302 and the side baffle 201 can be adjusted to two positions.
