[0068] As Figures 1 to 5 As shown in Figures 1 to 5 , an embodiment of the present application provides a milk powder dispenser 1, including a powder discharging device 200. The powder discharging device 200 includes a powder discharging port 210, a clamping member 220, and a clamping motor assembly 230. The clamping member 220 includes a first clamping arm 221 and a second clamping arm 222 that can relatively open and close to cover the powder discharging port 210, and the clamping motor assembly 230 is connected to the clamping member 220. Among them, the first clamping arm 221 and the second clamping arm 222 of the clamping member 220 are respectively disposed near the powder discharging port 210. When the first clamping arm 221 and the second clamping arm 222 are closed, the powder discharging port 210 is clamped, and when the first clamping arm 221 and the second clamping arm 222 are opened, the powder discharging port 210 is released. The first clamping arm 221 and the second clamping arm 222 are disposed on both sides of the powder discharging port 210 in the horizontal direction. After the powder discharging device 200 finishes discharging powder, the clamping motor assembly 230 drives the first clamping arm 221 and the second clamping arm 222 to repeatedly open and close, so that the powder discharging port 210 is repeatedly clamped and released by the clamping member 220, thereby shaking off the attached milk powder.

[0069] In some possible implementation manners, the powder discharging port 210 is made of flexible silica gel material, and can be pressed and clamped by the first clamping arm 221 and the second clamping arm 222 of the clamping member 220 when the clamping member 220 is closed, so as to achieve a sealing effect and prevent the milk powder in the milk powder bin 250 connected above the powder discharging port 210 from getting damp.

[0070] In some possible implementation manners, the powder discharging device 200 further includes a jetting assembly (not shown in the figure). The airflow jetted by the jetting assembly can blow off the remaining milk powder at the powder discharging port 210. Specifically, the jetting assembly can be disposed in the hollow first clamping arm 221 and second clamping arm 222, or can be independently disposed near the powder discharging port 210 or inside the powder discharging port 210.

[0071] In some possible implementation manners, the clamping motor assembly 230 is connected to the first clamping arm 221 through a cam mechanism 240. The cam mechanism 240 includes a disk cam 241, a second roller 242, and a follower rod 243. The disk cam 241 is axially connected to the output end of the clamping motor assembly 230. One end of the follower rod 243 is provided with the second roller 242, and the other end is connected to the rotating end 221a of the first clamping arm. AsFigure 6 and Figure 7 As shown in Figure 7 , the disc cam 241 has a structure with one end protruding horizontally. When the clamping motor assembly 230 drives the disc cam 241 to rotate, when the protruding portion of the disc cam 241 rotates to abut against the driven rod 243, the driven rod 243 opens a certain angle relative to the second clamping arm 221. Further, the driven rod 243 drives the first clamping arm 221 to rotate closer to the second clamping arm 222, so that the powder outlet 210 is clamped by the first clamping arm 221 and the second clamping arm 222. A return spring 244 is also horizontally arranged on the driven rod 243. When the protruding portion of the disc cam 241 rotates away from the driven rod 243, under the traction of the return spring 244, the driven rod 243 can close a certain angle relative to the second clamping arm 221, and the driven rod 243 drives the first clamping arm 221 to rotate away from the second clamping arm 222, so that the powder outlet 210 is released by the first clamping arm 221 and the second clamping arm 222. The second roller 242 rotatably connected to the driven rod 243 abuts against the disc cam 241, which can reduce the resistance during the transmission between the driven rod 243 and the disc cam 241 and reduce the noise during the transmission process. The driven rod 243 is arranged in the tangential direction of the disc cam 241, and the tangential direction of the contour line of the disc cam 241 determines the speed and acceleration of the driven rod 243. The design that the driven rod 243 is tangent to the disc cam 241 makes the movement of the driven rod 243 stable and can reduce impact and vibration.

[0072] In some possible embodiments, a second driving gear 221b is provided at the rotating end 221a of the first clamping arm, and a first clamping plate 221c is provided at the clamping end. A second driven gear 222b is provided at the rotating end 222a of the second clamping arm, and a second clamping plate 222c is provided at the clamping end. The first clamping arm 221 and the second clamping arm 222 are meshed and connected through the second driving gear 221b and the second driven gear 222b. Through the meshing connection of the gears, driving a single driven rod 243 can drive the first clamping arm 221 and the second clamping arm 222 to open or close simultaneously, with a compact structure and reduced space occupation. Since the first clamping arm 221 and the second clamping arm 222 only need to be able to clamp or release the powder outlet 210, both the second driving gear 221b and the second driven gear 222b are set as incomplete gear structures, and the number of teeth of the second driving gear 221b and the second driven gear 222b is the same. The incomplete gear structure can limit the opening angle of the clamping member 220, prevent the opening angle from being too large and causing detachment, improve stability, and the arc length of the number of teeth of the incomplete gear structure can be set to be equivalent to the radius of the powder outlet 210, so that when the first clamping arm 221 and the second clamping arm 222 are relatively closed to clamp the powder outlet 210, each presses half of the powder outlet 210, balancing the acting forces of the first clamping arm 221 and the second clamping arm 222 on the powder outlet 210 respectively, and the deformation degrees of the two side walls of the powder outlet 210 being clamped are roughly the same, so that the remaining milk powder in the powder outlet 210 directly falls into the milk bottle 170.

[0073] In some possible embodiments, the butt-joint portions of the first clamping arm 221 and the second clamping arm 222 are both set as lower step structures 223. The main bodies of the first clamping arm 221 and the second clamping arm 222 sink synchronously to form a groove structure. The clamping end of the first clamping arm 221 includes a first clamping section 221d, and the first clamping section 221d is arranged between the first clamping plate 221c and the second driving gear 221b. The sinking depth of the first clamping plate 221c is greater than the sinking depth of the first clamping section 221d; the clamping end of the second clamping arm 222 includes a second clamping section 222d, and the second clamping section 222d is arranged between the second clamping plate 222c and the second driven gear 222b. The sinking depth of the second clamping plate 222c is greater than the sinking depth of the second clamping section 222d. The main body parts of the first clamping arm 221 and the second clamping arm 222 are in a two-stage sinking groove structure. The first clamping section 221d and the second clamping section 222d of this downward-sinking groove structure improve the rigidity strength of the first clamping arm 221 and the second clamping arm 222, and the first clamping plate 221c and the second clamping plate 222c with a greater sinking depth can be closer to the end of the powder outlet 210 while improving the rigidity strength, and can make the milk powder attached to the powder outlet 210 easier to be shaken off.

[0074] In some possible embodiments, the clamping motor assembly 230 includes a bottom plate 231, a clamping drive motor 232, and a top plate 233. The clamping drive motor 232 is mounted on the top plate 233. The cam mechanism 240, the second driving gear 221b, and the second driven gear 222b are horizontally mounted between the top plate 233 and the bottom plate 231. As shown in Figure 3 , the output shaft of the clamping drive motor 232 passes through the top plate 233 from above the top plate 233 and is axially connected to the disc cam 241. The first clamping arm 221 and the second clamping arm 222 are respectively rotatably connected between the top plate 233 and the bottom plate 231, restricting the swaying of the first clamping arm 221 and the second clamping arm 222 in the height direction and improving the stability of the transmission.

[0075] As shown in Figures 6 to 12 , the milk powder making machine 1 provided by the embodiment of the present application further includes a milk bottle holder 150, a milk bottle lifting mechanism 100, and a milk bottle detection mechanism (not shown in the figure) provided at the powder outlet 210. The milk bottle holder 150 is used to fix the milk bottle 170. The milk bottle lifting mechanism 100 is used to lift the milk bottle holder 150 to the powder outlet 210 or lower it to the original position. The milk bottle detection mechanism is used to detect the milk bottle 170 in the milk bottle holder 150.

[0076] In some possible embodiments, the milk bottle lifting mechanism 100 includes a lifting motor assembly 130 and a groove cam kinematic pair 110 or a screw rod lifting kinematic pair 121 connected to the lifting motor assembly 130.

[0077] In some possible embodiments, the milk bottle lifting mechanism 100 further includes a lifting part 180 with a hollow structure arranged along the height direction. The lifting part 180 is connected to the head of the screw rod lifting kinematic pair 121. The milk shaking mechanism 300 is arranged in the hollow structure inside the lifting part 180. As shown in Figures 9 to 11 , the screw rod lifting kinematic pair 121 has a lifting member 1211 (i.e., the head of the screw rod lifting kinematic pair 121) rigidly connected to the lifting part 180. The screw rod lifting kinematic pair 121 is a mechanical device that uses the screw-nut screw pair to convert the rotational motion into a linear motion. The lifting member 1211 of the screw rod lifting kinematic pair 121 is rigidly connected to the lifting part 180, so that when the screw rod lifting kinematic pair 121 drives the lifting member 1211 to lift or lower by rotation, it drives the lifting part 180 to rise or fall.

[0078] In some possible embodiments, the outer wall of the lifting portion 180 is provided with a first protrusion 181, which is fixedly connected to the lifting member 1211. The screw lifting joint 121 also includes a rotating screw 1212 arranged in the height direction, the rotating screw 1212 being axially connected to the second lifting motor 133, and a lifting member 1211 having an internal threaded hole, and the lifting member 1211 is sleeved on the rotating screw 1212 through the internal threaded hole. The first protrusion 181 provided on the outer wall of the lifting portion 180 is used to be fixedly connected to the lifting member 1211 and load the lifting portion 180 to rise or fall. The rotating screw 1212 is arranged in the height direction, so that when the second lifting motor 133 drives the rotating screw 1212 to rotate, the lifting member 1211 rises or falls along the rotating screw 1212. Lifting member 1211 includes a mounting plate 1211a with an internally threaded hole. A first protrusion 181 is secured to mounting plate 1211a, enhancing the rigidity between the lifting member 1211 and first protrusion 181 and preventing them from falling off. The portion where mounting plate 1211a interfaces with lifting member 180 is designed as a cut surface, creating a more compact structure between rotating screw 1212 and lifting member 180. Lifting member 1211 also includes an internally threaded post 1211b extending downward from the internally threaded hole in mounting plate 1211a. This increases the length of the threaded connection between lifting member 1211 and rotating screw 1212, enhancing transmission stability.

[0079] In some possible embodiments, the mounting base 190 further includes at least one guide rod 197 arranged along the height direction. The outer side wall of the lifting portion 180 is further provided with at least one second protrusion 182, and at least one guide rod 197 is fixed to the mounting base 190 through the second protrusion 182. The guide rod 197 arranged along the height direction makes the lifting portion 180 more stable during the lifting process. The number of guide rods 197 and second protrusions 182 can be set to multiple to achieve a better balancing effect. A limiting ring 183 is also provided between the guide rod 197 and the second protrusion 182 to limit the displacement of the guide rod 197 in the second protrusion 182 and improve the stability of the lifting portion 180.

[0080] In some possible embodiments, the mounting base 190 includes a cylinder 191 sleeved outside the lifting part 180, a partition 192 disposed near the bottom of the cylinder 191, and an upper plate 193 disposed at the top of the cylinder 191. The second lifting motor 133 is disposed below the partition 192. The top end of the rotating screw 1212 is rotatably fixed to the upper plate 193, and the bottom end passes through the partition 192 and is axially connected to the second lifting motor 133. The partition 192 fixedly connected to the bottom of the cylinder 191 and the upper plate 193 disposed at the top fix the rotating screw 1212 in the height direction and play a protective role. The partition 192 is also provided with a motor mounting hole 1921. The second lifting motor 133 is fixedly mounted on the bottom of the partition 192 through the motor mounting hole 1921, making the structure compact. The first convex part 181 is disposed at the bottom of the cylinder 191 to increase the maximum rising height of the lifting part 180, so as to adapt to more milk bottles 170 of different heights. And the second convex part 182 can also be disposed at the bottom of the cylinder 191 to balance the load distributed to the first convex part 181 and the second convex part 182 by the lifting part 180.

[0081] In some possible embodiments, at least one set of limiting holes 194 opposite to each other in the height direction are further provided on the partition 192 and the upper plate 193. Each set of limiting holes 194 can accommodate a rotating screw 1212 or a guide rod 197. The limiting holes 194 can limit the horizontal movement of the rotating screw 1212 or the guide rod 197, preventing the lifting part 180 from shaking during the lifting process. The limiting holes 194 protrude from the lower surface of the upper plate 193 / the upper surface of the partition 192, increasing the height of the limiting holes 194 and strengthening the limiting effect. A reinforcing rib 195 is further provided between the limiting holes 194 and the inner wall of the cylinder 191 to enhance the strength of the limiting holes 194.

[0082] In some possible embodiments, a third convex part 196 is further provided on the outer side wall of the mounting base 190. A pin (not shown in the figure) fixedly connected to the outer side wall of the mounting base 190 can be installed in the third convex part 196, so that the side wall of the mounting base 190 can be opened along the third convex part 196, facilitating installation and disassembly.

[0083] In some possible embodiments, the groove cam pair 110 includes a cylindrical cam 111 with a hollow structure arranged in the height direction, and the milk shaking mechanism 300 is arranged in the hollow structure of the cylindrical cam 111. The groove cam pair 110 includes a sleeved cylindrical cam 111 and a driven lifting cylinder 112. Transmission teeth forming a first driven gear 1111 are arranged on the surface of the cylindrical cam 111. The lifting motor assembly 130 is meshed with the first driven gear 1111 through a first driving gear 131 connected axially. The groove on the groove cam pair 110 is connected to the driven lifting cylinder 112. The lifting motor assembly 130 drives the first driving gear 131 to drive the first driven gear 1111 to rotate, so that when the cylindrical cam 111 rotates, it drives the driven lifting cylinder 112 to rise or fall. By converting the rotational motion of the cylindrical cam 111 into the linear motion of the driven lifting cylinder 112 in the height direction, the function of lifting and lowering the milk bottle 150 in the milk bottle holder 150 is realized. When the milk bottle lifting mechanism 100 is arranged below the powder outlet 210 of the milk powder machine 1, milk bottles 150 at different heights can rise to the powder outlet 210, preventing milk powder from spilling.

[0084] In some possible embodiments, a motor mounting bracket 142 with a height equivalent to that of the first driving gear 131 is arranged on the base 140. The output shaft of the first lifting motor 132 is installed downward on the upper side of the motor mounting bracket 142, and the first driving gear 131 is horizontally installed on the lower side of the motor mounting bracket 142 and axially connected to the output shaft. As Figure 4 shown, the motor mounting bracket 142 is set as a suspended plate structure, and the first driving gear 131 is fixedly rotatably connected to the base 140, improving the stability of the lifting rotation drive and making the structure of the lifting motor assembly 130 more compact. Correspondingly, the first driven gear 1111 is arranged at the bottom end of the cylindrical cam 111. The transmission radius of the first driving gear 131 is set to be equivalent to the radius of the first lifting motor 132, making the structure more compact.

[0085] In some possible embodiments, the first driving gear 131 is a complete gear structure, and the first driven gear 1111 is an incomplete structure, wherein the transmission radius of the first driving gear 131 is equivalent to the radius of the first lifting motor 132. Since the lifting height converted by the groove cam pair 110 is related to the circumference of the rotation of the cylindrical cam 111, that is, the arc length of the rotation of the first driven gear 1111. In the embodiments of the present application, the transmission radius of the milk bottle lifting mechanism 100 sleeved outside the milk bottle is relatively large compared with the size of the milk bottle and the height to be raised. Therefore, in order to save materials and facilitate production, the first driven gear 1111 is set as a section of driven rack along the circumferential direction of the outer wall of the cylindrical cam 111. As Figure 5As shown in the figure, an arc-shaped flange 1112 is further provided on the side wall surface of the cylindrical cam 111. The arc-shaped flange 1112 and the first driven gear 1111 of the incomplete gear structure are connected end to end to form a circular shape. The arc-shaped flange 1112 protrudes horizontally relative to the side wall of the cylindrical cam 111. The height of the protrusion of the arc-shaped flange 1112 should not be less than the tooth height of the first driven gear 1111 to prevent the first driven gear 1111 from directly contacting the housing, playing a role in protecting the first driven gear 1111.

[0086] In some possible embodiments, multiple curved grooves 1113 are provided on the surface of the cylindrical cam 111. The multiple curved grooves 1113 are symmetrically distributed along the axis of the cylindrical cam 111. At least one first roller 1121 extending into the curved groove 1113 is provided on the surface of the driven lifting cylinder 112. The curved groove 1113 extends upward along the circumferential direction of the cylindrical cam 111. The multiple symmetric curved grooves 1113 can balance the force, making the transmission of the milk bottle lifting mechanism 100 more stable. The first roller 1121 can reduce the friction force during movement in the curved groove 1113, improve the transmission efficiency, and reduce the power consumption of the motor. The first roller 1121 is arranged close to the bottom end of the curved groove 1113, which can increase the maximum height of the driven lifting cylinder 112 to move up and down, so that the milk bottle lifting mechanism 100 can adapt to more milk bottles of different sizes. The arc length of the first driven gear 1111 of the incomplete gear structure is not less than the length of the positive projection of a single curved groove 1113 on the horizontal plane. During the operation of the milk bottle lifting mechanism 100, the horizontal distance that the first roller 1121 moves along the curved groove 1113 is equal to the arc length of the rotation of the first driven gear 1111. Therefore, in order to improve the utilization rate of the curved groove 1113, the arc length of the first driven gear 1111 should not be less than the length of the positive projection of the curved groove 1113 on the horizontal plane.

[0087] In some possible embodiments, the milk bottle lifting mechanism 100 further includes a guiding part connected to the driven lifting cylinder 112. The milk bottle lifting mechanism 100 further includes a protective cover 160 extending upward from the outer edge of the base 140 to above the cylindrical cam 111. Further, the guiding part includes at least one rib 1122 provided on the outer surface of the driven lifting cylinder 112 in the height direction and at least a pair of guide rails 1411 provided on the guide rail mounting frame 141. The rib 1122 can slide up and down into the guide rail 1411. As Figure 5As shown, the guide rail 1411 and the rib 1122 are both arranged in the height direction to limit the lateral movement of the driven lifting cylinder 112, so that it can smoothly lift along the guide rail 1411. To enhance the strength of the guide rail 1411, the guide rail mounting bracket 141 includes at least one guide rail mounting plate 1412 extending upward from the base 140 and a guide rail fixing ring 1413 provided at the top of the at least one guide rail mounting plate 1412, and the guide rail 1411 can be arranged between the side walls of the cylindrical cam 111 and the driven lifting cylinder 112, making the structure compact. The guide rail mounting plate 1412 can enhance the strength of the guide rail 1411. When multiple guide rails 1411 are provided for balanced guiding, multiple guide rail mounting plates 1412 are also correspondingly provided. The guide rail fixing ring 1413 can prevent multiple guide rails 1411 from shaking and improve the stability of guiding.
