[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] This invention provides, for example Figure 1-8 The injection dispensing device of the dispensing machine shown includes:

[0027] The base 1 has a cover plate 3 installed at its top, which facilitates the restriction of the top of the medicine bottle.

[0028] The dispensing device 2 is mounted on the base 1. The dispensing device 2 includes an injection storage rack 21 and a dispensing mechanism 22. The injection storage rack 21 is mounted on the base 1, and the dispensing mechanism 22 is located at one end of the injection storage rack 21. The injection storage rack 21 facilitates the carrying of medicine bottles. The dispensing mechanism 22 includes a rotating pushing mechanism 221, a lifting mechanism 222, a limiting mechanism 223, and a flat dispensing mechanism 224. The rotating pushing mechanism 221 is mounted on the bottom of the injection storage rack 21, and one end of the rotating pushing mechanism 221 is connected to the lifting mechanism 224. 2. The limiting mechanism 223 is connected to both sides of the injection storage rack 21. The flat-laying drug delivery mechanism 224 is slidably set between the limiting mechanisms 223. The rotating pushing mechanism 221 drives the lifting mechanism 222 to move upward. With the limiting of the two limiting mechanisms 223, the flat-laying drug delivery mechanism 224 moves upward and flips, falling to the drug receiving platform to complete the drug dispensing. This realizes the automatic dispensing of injection bottles, preventing manual handling from knocking over the bottles. The bottles can also be dispensed in sequence according to the order of their placement under the limiting of the injection storage rack 21.

[0029] The rotary pushing mechanism 221 includes a motor 2211, a crank 2212, and a rocker arm 2213. The output end of the motor 2211 is connected to a main shaft. One end of the main shaft is rotatably connected to one end of the crank 2212, and the other end of the crank 2212 is rotatably connected to one end of the rocker arm 2213. The motor 2211 is fixedly mounted on the lower surface of the base plate 211 by a mounting bracket. The motor 2211 is electrically connected to an external power source through an external switch. The rotation of the main shaft facilitates the rotation of the crank 2212, thereby realizing the swing of the rocker arm 2213 and providing a power source for the vertical movement of the connecting seat 2221.

[0030] The lifting mechanism 222 includes a connecting seat 2221, a sliding shaft 2222, and a third link 2223. The bottom of the connecting seat 2221 is rotatably connected to the other end of the rocker arm 2213. The two ends of the sliding shaft 2222 are inserted and connected to the two sides of the connecting seat 2221. The bottom of the third link 2223 is rotatably inserted and connected to one end of the sliding shaft 2222. The top of the third link 2223 is rotatably inserted and connected to the follower rod 2242. The connecting seat 2221 facilitates the support of the sliding shaft 2222, allowing the connecting seat 2221 to push the sliding shaft 2222 to move vertically under the limit of the linear slide rail 2231. The third link 2223 facilitates the connection and limitation of the position between the sliding shaft 2222 and the follower rod 2242.

[0031] The limiting mechanism 223 includes a linear slide 2231, a drug delivery guide frame 2232, and a guide groove 2233. The two linear slides 2231 are respectively connected to the two side plates 212. The drug delivery guide frame 2232 is installed on one of the linear slides 2231. The guide groove 2233 is opened on the inner side of the drug delivery guide frame 2232. The linear slide 2231 has a vertical through groove, which makes the vertical sliding of the sliding shaft 2222 and the follower rod 2242 more stable. Through the guide groove 2233 on the drug delivery guide frame 2232, the Z-shaped end of the follower rod 2242 is limited, so that after the follower rod 2242 moves up to a certain extent, the upward movement is accompanied by rotation.

[0032] The horizontal medicine delivery mechanism 224 includes a medicine delivery carriage 2241 and a follower rod 2242. The follower rod 2242 is rotatably connected to the bottom of the medicine delivery carriage 2241, so that the medicine delivery carriage 2241 can be supported by the follower rod 2242. After the medicine delivery carriage 2241 moves up to a certain distance, it flips over, and the medicine delivery carriage 2241 can support the medicine bottle.

[0033] The injection storage rack 21 includes a base plate 211 and two side plates 212. The two side plates 212 are respectively connected to the two sides of the upper surface of the base plate 211. The base plate 211 is installed on the base 1. The base plate 211 facilitates the support of injection vials, and the two side plates 212 facilitate the limitation of the two sides of the vials, thus facilitating the limitation of the dispensing of the vials.

[0034] Working principle of this invention:

[0035] In use, the injection or medicine box is first placed inside the injection storage rack 21. Then, the base 1 is installed at an angle on an external shelf, causing the injection or medicine box to slide towards the dispensing mechanism 22 due to gravity. When dispensing the injection or medicine box, the motor 2211 drives the main shaft to rotate, which in turn drives one end of the crank 2212 to rotate. Through the rotational connection between the crank 2212 and the rocker arm 2213, the rotation of the crank 2212 drives the rocker arm 2213 to swing. The rocker arm 2213 drives the connecting seat 2221 to move upward, lifting the connecting seat 2221. Through the connection between the follower rod 2242 and the sliding shaft 2222 via the third connecting rod 2223, the follower rod 2242... 42 and sliding shaft 2222 will move upward under the limitation of the straight slide rails 2231 on both sides. When the movement reaches a certain position, due to the Z-shaped shape of the end of the follower rod 2242, under the simultaneous limitation of the straight slide rail 2231 and the drug delivery guide frame 2232, the straight part of the follower rod 2242 still slides in the inner cavity of the straight slide rail 2231, but the Z-shaped end of the follower rod 2242 will move according to the trajectory of the inner cavity of the guide groove 2233 on the drug delivery guide frame 2232, so that the follower rod 2242 slides in the straight slide rail 2231 while rotating, thereby driving the drug delivery carriage 2241 to rotate. When the drug delivery carriage 2241 rotates to a certain angle, the injection or medicine box will slide forward under the action of weight and fall onto the receiving platform to complete the drug delivery.

[0036] When the crank 2212 rotates 180 degrees, the stroke reaches its highest point. Continued rotation will cause the rocker arm 2213 to swing. The rocker arm 2213 drives the connecting seat 2221 to reset, and the follower rod 2242 drives the drug delivery carriage 2241 to reset. The motor 2211 stops running and returns to the initial position of ready-to-dispense state, thus realizing the automatic dispensing of injection vials.

[0037] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
