Description

Technical Field

[0001] This utility model belongs to the field of vending machine technology, and specifically relates to a beverage vending machine with a grinding mechanism. Background Technology

[0002] Consumers typically obtain freshly ground beverages (mainly coffee, but also including soy milk, sesame paste, etc.) through two channels: physical stores (hand-ground and prepared) and vending machines. Currently, people live fast-paced lives, and to save time, most choose vending machines that process beverages more quickly.

[0003] Existing vending machines cannot automatically clean the raw materials adhering to the grinding system during the grinding process, resulting in unstable raw material content in beverages and insufficient taste and flavor.

[0004] Therefore, there is an urgent need for a beverage vending machine with a grinding mechanism to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: A beverage vending machine with a grinding mechanism, comprising a vending machine body, movably mounted on the ground, and further comprising a fixing component, a grinding mechanism, and a vibration mechanism, including a mounting frame and a limiting cover. The mounting frame is fixed to the inner wall of the vending machine body, and the limiting cover is fixed to the mounting frame. The grinding mechanism includes a lower grinding disc and an upper grinding disc, both of which are rotatably mounted within the mounting frame, with the upper grinding disc located on the lower grinding disc. The upper grinding disc has a feeding hole at its center, and the lower grinding disc has multiple discharging holes around its edge. The vibration mechanism includes a rotating component, with an annular space between the lower and upper grinding discs. The rotating component is rotatably mounted within the annular space, and one end of the rotating component intermittently contacts the peripheral walls of the lower and upper grinding discs.

[0006] As a further improvement of this utility model, the bottom of the upper grinding disc is configured as a concave conical surface, the top of the lower grinding disc is configured as a convex conical surface, and a grinding channel is formed between the concave conical surface of the upper grinding disc and the convex conical surface of the lower grinding disc. The size of the grinding channel gradually decreases from the center to the edge, and the grinding channel is connected to multiple discharge holes.

[0007] As a further improvement of this utility model, it also includes a drive assembly, including a servo motor, a rotating shaft, a first gear and a second gear. The servo motor is fixedly installed on the upper end of the limiting cover, the rotating shaft is fixed to the output end of the servo motor, and the rotating shaft rotates through the inner wall of the limiting cover. The first gear is fixed on the rotating shaft, and the second gear is fixed on the outer peripheral wall of the lower grinding disc. The first gear meshes with the second gear, and the second gear is rotatably mounted on the inner wall of the limiting cover.

[0008] As a further improvement of this utility model, the drive assembly further includes gear three, gear four and gear five. Gear three is fixed on the rotating shaft, gear four is rotatably mounted inside the limiting cover, gear five is fixed on the outer peripheral wall of the lower grinding disc, and gear five is rotatably mounted on the inner wall of the limiting cover. Gear three meshes with gear four, and gear four meshes with gear five.

[0009] As a further improvement of this utility model, it also includes a transmission component, specifically including a worm gear and a rotating shaft. The input end of the worm gear is fixed on the rotating shaft, and the output end of the worm gear is rotatably mounted inside the limiting cover. One end of the rotating shaft is fixed to the output end of the worm gear, and the other end rotatably passes through the limiting cover and is rotatably mounted in the annular space. The rotating component is fixed on the rotating shaft.

[0010] As a further improvement of this utility model, the rotating component includes a connecting rod, a striking rod, and a spring. The connecting rod is fixed on the rotating shaft, the striking rod is slidably mounted on the connecting rod, and the spring is connected between the striking rod and the connecting rod.

[0011] As a further improvement of this utility model, it also includes a storage box, which is fixed on the inner wall of the vending machine body. The bottom of the storage box is provided with multiple distributing hoppers, and the lower ends of the multiple distributing hoppers are connected to a mixing box. The bottom of the mixing box is fixed with a guide pipe, and the guide pipe is connected to the feed hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By using a vibration mechanism, during the grinding process, the rotating part rotates in an annular space. The rotating part can alternately impact the peripheral walls of the lower and upper grinding discs, thereby generating a vibration effect between the lower and upper grinding discs. As a result, the material adhering to the upper and lower grinding discs can be detached under the action of vibration. On the one hand, this avoids the blockage of materials during the grinding process and improves the smoothness of grinding. On the other hand, it ensures that the material can completely enter the next process after each grinding, ensuring the stability of the raw material content in the beverage and thus avoiding the situation of insufficient flavor in the beverage.

[0014] 2. By using the drive and transmission components in synergy, a single motor can drive the upper and lower grinding discs to rotate in opposite directions to achieve grinding, and at the same time drive the striking rod to alternately strike the upper and lower grinding discs to achieve vibration discharge. This achieves multiple uses in one machine, reduces investment costs, and improves the practicality of the device. Attached Figure Description

[0021] See Figures 1 to 5 As shown, a beverage vending machine with a grinding mechanism includes a vending machine body 1, which is movably mounted on the ground. It also includes a fixing component, a grinding mechanism 2, and a vibration mechanism. The fixing component includes a mounting frame 11 and a limiting cover 12. The mounting frame 11 is fixed to the inner wall of the vending machine body 1, and the limiting cover 12 is fixed to the mounting frame 11. The grinding mechanism 2 includes a lower grinding disc 21 and an upper grinding disc 22, both rotatably mounted within the mounting frame 11. The upper grinding disc 22 is located on the lower grinding disc 21. The upper grinding disc 22 has a feed hole 221 at its center, and the lower grinding disc 21 has multiple discharge holes 211 around its edge. The vibration mechanism includes a rotating component 31. An annular space 32 is provided between the lower grinding disc 21 and the upper grinding disc 22. The rotating component 31 is rotatably mounted within the annular space 32, and one end of the rotating component 31 intermittently contacts the peripheral walls of the lower grinding disc 21 and the upper grinding disc 22.

[0022] It should be explained that, under the action of external force, when the lower grinding disc 21 rotates clockwise, the upper grinding disc 22 rotates counterclockwise, so that the upper grinding disc 22 and the lower grinding disc 21 can grind the material between them.

[0023] Specifically, during the grinding process, the rotating part 31 rotates within the annular space 32. The rotating part 31 can alternately impact the peripheral walls of the lower grinding disc 21 and the upper grinding disc 22, thereby generating a vibration effect between the lower grinding disc 21 and the upper grinding disc 22. Consequently, the material adhering to the upper grinding disc 21 and the lower grinding disc 22 can be detached under the vibration. Therefore, on the one hand, it avoids the blockage of materials during the grinding process and improves the smoothness of grinding. On the other hand, it ensures that the material can completely enter the next process after each grinding, ensuring the stability of the raw material content in the beverage and thus avoiding insufficient taste and flavor in the beverage.

[0024] In a preferred embodiment, the bottom of the upper grinding disc 22 is configured as a concave conical surface, and the top of the lower grinding disc 21 is configured as a convex conical surface. The concave conical surface of the upper grinding disc 22 and the convex conical surface of the lower grinding disc 21 form a grinding channel 4. The size of the grinding channel 4 gradually decreases from the center to the edge, and the grinding channel 4 is connected to a plurality of discharge holes 211.

[0025] In other words, the material to be ground enters the grinding channel 4 through the feed hole 221. After being ground by the upper grinding disc 22 and the lower grinding disc 21, the material will be gradually ground to the target particle size and finally enter the next process through multiple discharge holes 211.

[0026] It should be explained that the lower grinding disc 21 can exert a certain centrifugal force on the material in the grinding channel 4 during rotation, which facilitates the overall movement of the material from the center to the edge.

[0027] In a preferred embodiment, a drive assembly is also included, comprising a servo motor 51, a rotating shaft 52, a first gear 53, and a second gear 54. The servo motor 51 is fixedly mounted on the upper end of the limiting cover 12. The rotating shaft 52 is fixed to the output end of the servo motor 51 and rotates through the inner wall of the limiting cover 12. The first gear 53 is fixed on the rotating shaft 52, and the second gear 54 is fixed on the outer peripheral wall of the lower grinding disc 21. The first gear 53 meshes with the second gear 54, and the second gear 54 is rotatably mounted on the inner wall of the limiting cover 12.

[0028] When the servo motor 51 starts, it can drive the rotating shaft 52 to rotate. The rotating shaft 52 will drive the gear 1 53 to mesh with the gear 2 54, thereby driving the upper grinding disc 22 to rotate.

[0029] In a preferred embodiment, the drive assembly further includes gear three 55, gear four 56, and gear five 57. Gear three 55 is fixed on the rotating shaft 52. Gear four 56 is rotatably mounted inside the limiting cover 12. Gear five 57 is fixed on the outer peripheral wall of the lower grinding disc 21 and is rotatably mounted on the inner wall of the limiting cover 12. Gear three 55 meshes with gear four 56, and gear four 56 meshes with gear five 57.

[0030] When the servo motor 51 starts, it drives the rotating shaft 52 to rotate. The rotating shaft 52 drives gear 3 55 to mesh with gear 4 56, and gear 4 56 to mesh with gear 5 57, thereby driving the lower grinding disc 21 to rotate. Moreover, when the rotating shaft 52 rotates clockwise, the upper grinding disc 22 rotates counterclockwise, and the lower grinding disc 21 rotates clockwise. That is, the upper grinding disc 22 and the lower grinding disc 21 rotate in opposite directions, which can realize the grinding action.

[0031] In addition, it should be noted that the upper grinding disc 22 and the lower grinding disc 21 are respectively limited by gear 2 54 and gear 5 57 through the inner wall of the limiting cover 12, ensuring that the upper grinding disc 22 and the lower grinding disc 21 only have circumferential rotational movement.

[0032] In a preferred embodiment, a transmission assembly is also included, specifically including a worm gear 61 and a rotating shaft 62. The input end (worm) of the worm gear 61 is fixed on the rotating shaft 52, and the output end (worm gear) of the worm gear 61 is rotatably mounted inside the limiting cover 12. One end of the rotating shaft 62 is fixed to the output end of the worm gear 61, and the other end rotatably passes through the limiting cover 12 and is rotatably mounted inside the annular space 32. The rotating component 31 is fixed on the rotating shaft 62.

[0033] In other words, the rotation of the shaft 52 will drive the input end of the worm gear 61 to rotate. After the worm and worm wheel mesh, the worm wheel will drive the rotating shaft 62 to rotate, and the rotating shaft 62 will drive the rotating component 31 to rotate. Therefore, the rotating component 31 can alternately strike the upper grinding disc 22 and the lower grinding disc 21.

[0034] In a preferred embodiment, the rotating component 31 includes a connecting rod 321, a striking rod 322, and a spring 323. The connecting rod 321 is fixed on the rotating shaft 62, the striking rod 322 is slidably mounted on the connecting rod 321, and the spring 323 is connected between the striking rod 322 and the connecting rod 321.

[0035] In detail, when the connecting rod 321 rotates synchronously with the rotating shaft 62, the spring 323 will contract to a certain length when the striking rod 322 touches the upper grinding plate 22 or the lower grinding plate 21, thereby ensuring that the striking rod 322 can smoothly pass over the upper grinding plate 22 or the lower grinding plate 21 under the premise of collision, and avoid jamming.

[0036] Furthermore, in summary, this application only requires one motor to drive the upper grinding disc 22 and the lower grinding disc 21 to rotate in opposite directions to achieve material grinding, and at the same time drive the striking rod 322 to alternately strike the upper grinding disc 22 and the lower grinding disc 21 to complete vibration discharge, thus achieving multiple uses in one machine, reducing investment costs, and improving the practicality of the device.

[0037] In a preferred embodiment, a storage box 71 is also included, which is fixed on the inner wall of the vending machine body 1. The bottom of the storage box 71 is provided with a plurality of distributing hoppers 72, and the lower ends of the plurality of distributing hoppers 72 are connected to a mixing box 73. The bottom of the mixing box 73 is fixed with a guide pipe 74, which is connected to the feed hole 221.

[0038] It should be noted that the storage box 71 is equipped with a partition, and different kinds of beverage ingredients are stored in the storage box 71. The mixing box 73 is equipped with a stirring device, which can fully mix the different kinds of ingredients released from the storage box 71. The mixed material will enter the grinding mechanism 2 through the feed pipe 74 for grinding.

[0039] Specifically, when it is necessary to grind beverage raw materials, the required material is first quantitatively released into the feed hole 221, the servo motor 51 is started, and under the transmission action of the drive component, the upper grinding disc 22 and the lower grinding disc 21 rotate in opposite directions to achieve gradual grinding. During this process, under the action of the transmission component, the striking rod 322 alternately strikes the upper grinding disc 22 and the lower grinding disc 21 to achieve complete material discharge, thus completing one grinding process.

[0040] 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 primarily defined by the scope of the claims.
