Detailed Implementation

[0025] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings. Example 1

[0026] Please see Figures 1 to 8 The present invention preferably provides a technical solution: a powder quantitative dispensing turntable device, comprising: a body 111; a feeding bin 112, a dispensing disc assembly, and a discharging bin 113 arranged sequentially from top to bottom on the body 111 and interconnected with each other, for the quantitative dispensing of powder; wherein, the dispensing disc assembly includes a transmission disc 211 installed in the middle of the body 111 and rotating intermittently, the transmission disc 211 having dispensing slots 212 evenly spaced and arranged in a ring inside, a push plate 214 slidably installed inside each dispensing slot 212 for adjusting the storage volume of the dispensing slot 212; and a discharge port 1131 opened in the middle of the discharging bin 113, wherein when the transmission disc 211 rotates, the dispensing slot 212 rotated to the lower part of the feeding bin 112 is used for the quantitative feeding of powder, and the dispensing slot 212 rotated to the discharging bin 113 and aligned with the discharge port 1131 is used for the discharging of powder.

[0027] like Figure 1-6 As shown, the feeding hopper 112, the dispensing tray assembly, and the discharging hopper 113 are distributed and interconnected from top to bottom. When the medicine powder is poured into the discharging hopper 113, as the transmission disc 211 where the dispensing tray assembly is located rotates intermittently, several dispensing slots 212 collect the medicine powder in equal amounts at the feeding hopper 112 position and discharge the medicine powder one by one from the discharging hopper 113 position.

[0028] The push plate 214 inside each dispensing slot 212 can be adjusted in position, such as... Figure 6 As shown, this allows for adjustment of the powder storage volume outside the corresponding dispensing tank 212, thereby adjusting the amount of powder dispensed and meeting different powder dispensing requirements.

[0029] Furthermore, the transmission disc 211 includes a central disc body and side shells fixed to both sides of the disc body. A plurality of dispensing slots 212 are equidistantly opened on the outer periphery of the disc body, and a scale is arranged in a ring on the disc body and corresponds one-to-one with the plurality of dispensing slots 212 for precise measurement of the volume of the plurality of dispensing slots 212.

[0030] The two side shells fixed on both sides of the disc body are preferably transparent shells, which facilitates observation of the operation of the dispensing disc assembly and the scale corresponding to each dispensing slot 212, thereby improving dispensing accuracy.

[0031] It is worth noting that the scale here is recessed to ensure the seal between the disc and the transparent shell.

[0032] Furthermore, a mounting bracket 220 is provided on the front side of the body 111, and a drive motor 221 is provided on the mounting bracket 220. A gear 222 is fixed to the output end of the drive motor 221; and a transmission ring 223 is fixed to the front side of the transmission disc 211. The outer circumference of the transmission ring 223 is fixed with arc-shaped teeth 224, wherein the gear 222 meshes with the arc-shaped teeth 224, and the meshing transmission distance between the two is equal to the distance between two adjacent sub-packing slots 212.

[0033] like Figure 3 As shown, since the transmission distance of gear 222 meshing with arc-shaped teeth 224 is equal to the distance between two adjacent sub-packing slots 212, when the drive motor 221 drives gear 222 to rotate one revolution, it is used for equidistant switching of the positions of several sub-packing slots 212. Example 2

[0034] In another embodiment of this utility model, each dispensing slot 212 is further provided with a transmission push sleeve structure; and a cam drive element fixed to the body 111 and extending to the middle of several transmission push sleeve structures. Under the action of the rotation of the transmission disc 211, several transmission push sleeve structures distributed in a ring rotate around the cam drive element and perform telescopic movement; each transmission push sleeve structure includes an assembly plate 213 fixed to the inner side of the dispensing slot 212, and a telescopic sleeve 215 is provided in the through hole opened in the middle of the assembly plate 213. The telescopic sleeve 215 has a telescopic push rod structure that is slidably installed with it and connected to the push plate 214 at one end. The other end of the cam drive element is provided with a roller 219 that contacts the cam drive element; and a first connecting ring 217 fixed in the middle of the telescopic sleeve 215. A first spring 218 is connected between the first connecting ring 217 and the outer wall of the telescopic sleeve 215 between the first connecting ring 217 and the assembly plate 213. Further, the cam drive element includes a horizontal bar 225 fixed on the back side of the machine body 111. A mounting post 226 is fixed in the middle of the horizontal bar 225. The end of the mounting post 226 away from the horizontal bar 225 is fixed with a cam body 227 that contacts a plurality of rollers 219. The cam body 227 has its convex end facing down and is aligned with the discharge port 1131 opened in the middle of the discharge bin 113.

[0035] like Figure 3 , 5 As shown in Figure 6, several transmission push sleeve structures are assembled inside several sub-packing slots 212. Specifically, the assembly plate 213 where a single transmission push sleeve structure is located is fixed to the inner side of the corresponding sub-packing slot 212. The telescopic sleeve 215, which is telescopically installed in the middle of the assembly plate 213, has a telescopic push rod structure inside one end that is fixed to the push plate 214. The roller 219 at the other end contacts the outer periphery of the cam body 227 where the cam drive element is located. Because the cam body 227 is fixedly installed while the transmission disc 211 is movably installed, when the transmission disc 211 rotates, the telescopic sleeves 215 where several transmission push sleeve structures are located roll and telescopically move along the outer periphery of the cam body 227 through the roller 219. And because the convex end of the cam body 227 faces downward and is aligned with the discharge port 1131 opened in the middle of the discharge bin 113, as shown in Figure 6, the telescopic sleeves 215 where several transmission push sleeve structures are located roll along the outer periphery of the cam body 227 through the roller 219. Figure 3 , 4 As shown in Figures 5 and 6, the transmission pusher structure that moves to the outlet 1131 pushes the push plate 214 downward and completes the discharge of the powder. The transmission pusher structure that moves to the feed hopper 112 is reset to the set position by the first spring 218 to adjust the dispensing hopper 212 to the set volume.

[0036] For example, when several rollers 219 such Figure 6During clockwise rotation, the cam body 227 causes several downward-moving telescopic sleeves 215 to gradually move into the dispensing groove 212, while several upward-moving telescopic sleeves 215 are reset. Since the machine body 111 closes the outside of the dispensing groove 212, the gradually upward-moving telescopic sleeves 215 are reset by the first spring 218, and when they reach the feed hopper 112, the dispensing groove 212 is reset to its initial volume. Meanwhile, the gradually downward-moving telescopic sleeves 215 extend into the dispensing groove 212 and compress the first spring 218. When the gradually downward-moving telescopic sleeves 215 reach the discharge port 1131, the cam body 227 pushes the telescopic sleeves 215 to the deepest part of the dispensing groove 212, at which point the push plate 214 pushes the powder out through the discharge port 1131.

[0037] Furthermore, a rubber ring is fixed to the outer periphery of each pusher plate 214 to improve the cleanliness of the powder pushed by the pusher plate 214. Example 3

[0038] In another embodiment of this utility model, each telescopic push rod structure includes a telescopic column 216 installed inside the telescopic sleeve 215. One end of the telescopic column 216 extends out of the telescopic sleeve 215 and is fixed to the side wall of the push plate 214. A bolt assembly is provided between the other end of the telescopic column 216 and the telescopic sleeve 215 for adjusting the degree of extension of the telescopic column 216 relative to the telescopic sleeve 215, so as to adjust the initial volume of the dispensing slot 212. Further, each bolt assembly includes a rectangular groove formed on the side of the telescopic sleeve 215 near the roller 219. The rectangular groove is provided with a rectangular frame 311; and a transmission rod 312, wherein one end of the transmission rod 312 is fixed to the end of the telescopic column 216 away from the push plate 214, and the other end is provided with a screw hole; it also includes a bolt body 313, and a stop block 314 fixed to the middle of the bolt body 313, and the diameter of the stop block 314 is larger than the transverse diameter of the transmission rod 312. When the bolt body 313 is threadedly connected to the screw hole at the end of the transmission rod 312, the stop block 314 abuts against the transmission rod 312 for locking after the position of the telescopic column 216 is adjusted.

[0039] like Figure 4 , 7 As shown in Figure 8, one end of the telescopic column 216 extends out of the telescopic sleeve 215 and is fixed to the push plate 214. The transmission rod 312 fixed at the other end can be connected to the bolt body 313 to clamp the abutment block 314 and the rectangular frame 311, thereby locking the position of the telescopic column 216 and adjusting the degree of extension of the telescopic column 216 relative to the telescopic sleeve 215 to meet the flexible adjustment of the dispensing amount. Example 4

[0040] As another embodiment of this utility model, the machine body 111 is also provided with a vibration assembly for accelerating the feeding and discharging of the powder; the vibration assembly includes a vibration motor 119 installed on the side wall of the feeding hopper 112; and columns 115 respectively fixed on both sides of the bottom of the machine body 111, wherein a second connecting ring 116 is fixed in the middle of each column 115, and a sleeve 114 is sleeved on its bottom end, and a second spring 117 is connected between the sleeve 114 and the second connecting ring 116 on the outer wall of the column 115; and also includes a foot pad 118 fixed on the bottom end of each sleeve 114.

[0041] like Figure 1 , 2 As shown in Figures 3 and 4, the vibration motor 119 here is a mature existing technology. Its principle is to install a set of adjustable eccentric blocks at each end of the rotor shaft, and use the centrifugal force generated by the high-speed rotation of the shaft and eccentric blocks to obtain the excitation force.

[0042] This application uses a vibration motor 119 mounted on the side wall of the feeding hopper 112 to accelerate the entry of the powder inside the feeding hopper 112 into the upper dispensing tank 212 and reduce the gaps in the powder inside the upper dispensing tank 212, thereby improving the dispensing accuracy. On the other hand, it reduces the amount of powder adhering inside the lower dispensing tank 212, thereby further improving the dispensing accuracy.

[0043] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "fixation" and other terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.

[0044] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
