[0023] The present invention relates to a medicine delivery mechanism. For example, the medicine delivery mechanism includes a tightening assembly, a feeding channel and a discharging channel, the tightening assembly includes a driving member and a rotating wheel, and the rotating wheel is fixed on the output shaft of the driving member. For example, a plurality of conveying grooves are concavely provided on the periphery of the rotating wheel, the feeding channel and the discharging channel are both arranged on the periphery of the rotating wheel, and the central axis of the feeding channel and the central axis of the discharging channel are parallel to each other and arranged at intervals. For example, an arc-shaped guide block is provided at one end of the feeding channel adjacent to the rotating wheel, a concave arc-shaped guide surface is formed on the arc-shaped guide block, and a rotating cylinder is provided at the end edge of the arc-shaped guide block. For example, the rotating cylinder is adjacent to the periphery of the rotating wheel, and the concave arc-shaped guide surface of the arc-shaped guide block is used to guide the medicine bottle into the corresponding conveying groove through the rotating cylinder. For example, an arched spring is convexly provided on the concave arc-shaped guide surface.

[0024] See also Figure 1 and Figure 2 A medicine delivery mechanism for delivering bottled medicine, comprising a tightening assembly 10, a feeding channel 20 and a discharging channel 30, wherein the tightening assembly 10 comprises a driving member 11 and a rotating wheel 12, wherein the rotating wheel 12 is fixed to the output shaft of the driving member 11, wherein the periphery of the rotating wheel 12 is concavely provided with a plurality of conveying grooves 121, wherein the feeding channel 20 and the discharging channel 30 are both arranged at the periphery of the rotating wheel 12, wherein the central axis of the feeding channel 20 is parallel to the central axis of the discharging channel 30. They are parallel to each other and arranged at intervals. An arc-shaped guide block 21 is provided at one end of the feeding channel 20 adjacent to the rotating wheel 12. A concave arc-shaped guide surface 22 is formed on the arc-shaped guide block 21. A rotating cylinder 23 is provided at the end edge of the arc-shaped guide block 21. The rotating cylinder 23 is adjacent to the periphery of the rotating wheel 12. The concave arc-shaped guide surface 22 of the arc-shaped guide block 21 is used to guide the medicine bottle into the corresponding conveying groove 121 through the rotating cylinder 23. An arched spring piece 24 is convexly provided on the concave arc-shaped guide surface 22.

[0025] When the medicine conveying mechanism is in use, multiple medicine bottles are conveyed along the feeding channel 20, so that the multiple medicine bottles are transported to the rotating cylinder 23 in sequence along the concave arc-shaped guide surface 22; the medicine bottles enter the conveying groove 121 of the rotating wheel 12 from the rotating cylinder 23, and the side surfaces of the conveying groove 121 and the circumferential surface of the rotating cylinder 23 define the opposite sides of the medicine bottles; the driving member 11 drives the rotating wheel 12 to rotate, so as to drive the medicine bottles to move laterally into the discharge channel 30; the discharge channel 30 conveys the medicine bottles away from the feeding channel 20; the arched spring piece 24 undergoes elastic deformation to buffer the squeezing force between the subsequent multiple medicine bottles.

[0026] When the medicine bottle is transported into the corresponding conveying groove 121, the side surfaces of the conveying groove 121 and the circumferential surface of the rotating cylinder 23 define the opposite sides of the medicine bottle. Therefore, the rotating cylinder 23 can be used to isolate excess medicine bottles outside the conveying groove 121, and the arched spring 24 can buffer the pressure of subsequent multiple medicine bottles to prevent the medicine bottles from being squeezed or damaged.

[0027] For example, in order to facilitate the conveying of medicine bottles, the feeding channel 20 includes a bottom plate 25, a first side plate 26 and a second side plate 27, and the first side plate 26 and the second side plate 27 are respectively vertically protruded on opposite sides of the bottom plate 25. The width of the feeding channel 20 is greater than the width of the discharging channel 30, the first side plate 26 is adjacent to one side of the rotating wheel disc 12, and the extension line of the second side plate 27 is aligned with the center of the rotating wheel disc 12. The arc guide block 21 is arranged on the first side plate 26, and the distance between the concave arc guide surface 22 and the second side plate 27 gradually decreases in the direction toward the rotating wheel disc 12. By providing the concave arc guide surface 22, the concave arc guide surface 22 gradually extends toward the second side plate 27, and then the width of the feeding channel 20 is gradually reduced, forcing the medicine bottle to move toward the rotating cylinder 23, and then it can smoothly enter the conveying groove 121 of the rotating wheel disc 12.

[0028] For example, in order to facilitate the smooth conveying of the medicine bottle from the feeding channel 20 to the discharging channel 30, the discharging channel 30 includes a base plate 31, a first baffle plate 32 and a second baffle plate 33, and the first baffle plate 32 and the second baffle plate 33 are respectively vertically protruded on opposite sides of the base plate 31. The first baffle plate 32 is adjacent to the first side plate 26, and the second baffle plate 33 is parallel to the first baffle plate 32, and the extension line of the second baffle plate 33 extends toward the center of the rotating wheel disk 12. The second baffle plate 33 is provided with an arc-shaped blocking piece 331 at the periphery of the rotating wheel disk 12, and the arc-shaped blocking piece 331 extends along the periphery of the rotating wheel disk 12. An arc-shaped wrapping piece 321 is provided at the end of the first baffle plate 32, and the arc-shaped wrapping piece 321 extends to the rotating cylinder 23, and an arc-shaped conveying channel 34 is defined between the arc-shaped wrapping piece 321 and the periphery of the rotating wheel disk 12. The two opposite ends of the arc conveying channel 34 are connected to the feeding channel 20 and the discharging channel 30 respectively, and the width of the discharging channel 30 is equal to the outer diameter of the medicine bottle. By providing the arc wrapping sheet 321, the arc conveying channel 34 is defined by the arc wrapping sheet 321, and then the arc conveying channel 34 can be used to transfer the medicine bottle from the feeding channel 20 to the discharging channel 30, thereby preventing the medicine bottle from moving at will and improving the smoothness of the transportation.

[0029] For example, it is especially important to also refer to Figure 3 and Figure 4 In order to facilitate guiding the medicine bottle to smoothly enter the corresponding conveying groove 121, the arc-shaped blocking piece 331 includes a connecting column 3311 and an arc-shaped sheet 3313. The connecting column 3311 is connected to the end of the second baffle 33, and the end edge of the arc-shaped sheet 3313 away from the connecting column 3311 is elastically pressed against the periphery of the rotating wheel 12 to prevent the medicine bottle from following the conveying groove 121 and escaping from the discharge channel 30. For example, a blocking beam 122 is formed between each two adjacent conveying grooves 121, and an air expansion cylinder 123 is arranged on one side of each blocking beam 122. The air expansion cylinder 123 is located on the side of the blocking beam 122 facing the rotating wheel 12. An air expansion cavity is formed in the rotating cylinder 23. A first air pump is also arranged at the bottom of the feeding channel 20, and a second air pump is arranged at the bottom of the rotating wheel 12. The first air pump is connected to the air expansion cavity of the rotating cylinder 23. The first air pump is used to adjust the pressure in the air expansion cavity of the rotating cylinder 23 to adjust the hardness of the peripheral surface of the rotating cylinder 23 and improve the guiding force for different medicine bottles. The second air pump is connected to the inner cavity of the air expansion cylinder 123. The second air pump is used to control the expansion and contraction of the air expansion cylinder 123. When the conveying groove 121 is adjacent to the rotating cylinder 23, the second air pump is used to drive the air expansion cylinder 123 to expand, and the air expansion cylinder 123 is used to assist the blocking beam 122 to push the medicine bottle into the conveying groove 121.

[0030] For example, in order to facilitate lubrication of the peripheral surface of the medicine bottle to prevent the peripheral surface of multiple medicine bottles from being scratched or squeezed, a plurality of overflow mesh holes are provided on the arc-shaped wrapping sheet 321, and the plurality of overflow mesh holes are all circular holes. A through groove is provided on the concave arc-shaped guide surface 22, and the through groove extends to the arc-shaped wrapping sheet 321, and the arched spring piece 24 blocks the through groove. A sponge column 225 is provided in the through groove, and a lubricating oil barrel is connected to the top of the sponge column 225, and the lubricating oil barrel is used to keep the sponge column 225 immersed in lubricating oil at all times. One side of the sponge column 225 abuts against the arc-shaped wrapping sheet 321, and the other side abuts against the arched spring piece 24, and a plurality of oil holes are provided on the arched spring piece 24. When the squeeze of multiple medicine bottles is relatively serious, the arched spring piece undergoes elastic deformation and squeezes the sponge column 225, so that the lubricating oil in the sponge column 225 overflows from the arched spring piece 24 through the plurality of oil holes to lubricate the multiple medicine bottles and prevent the multiple medicine bottles from being squeezed. At the same time, the lubricating oil of the sponge column 225 enters the arc conveying channel 34 through the multiple overflow meshes of the arc-shaped wrapping sheet 321 to lubricate the medicine bottle in the arc conveying channel 34. For example, in order to facilitate the guiding effect of the air expansion cylinder 123 on the medicine bottle, a push assembly 28 is also provided on one side of the second side plate 27, and the push assembly includes a thrust cylinder 281 and an arc-shaped push sheet 283. The thrust cylinder 281 is installed on the side of the second side plate 27 away from the first side plate 26, and the middle part of the arc-shaped push sheet 283 is connected to the output shaft of the thrust cylinder 281. One end of the arc-shaped push sheet 283 is movably abutted on the second side plate 27, and the other end extends in an arc toward the air expansion cylinder 123. The thrust cylinder 281 is used to drive the arc-shaped push sheet 283 to move, so as to use the arc-shaped push sheet 283 to guide the medicine bottle into the conveying groove 121.

[0031] For example, in order to facilitate tightening the bottle cap, the tightening assembly 10 further includes a power disc 13, a plurality of tightening structures 15, a sun gear ring 16 and a guide ring 17, and the power disc 13 is coaxially fixed above the rotating wheel disc 12. The plurality of tightening structures 15 are rotatably and evenly spaced on the periphery of the power disc 13, the sun gear ring 16 is coaxially arranged on the outside of the power disc 13, the axial dimension of the sun gear is 2-3 times the axial dimension of the power disc 13, and the sun gear ring 16 is fixed to the first side plate 26, the second side plate 27 and the first baffle 32 through a plurality of fixing rods 14, so that the sun gear ring 16 is fixed relative to the feeding channel 20 and the discharging channel 30. Multiple tightening structures 15 are all meshed with the inner side of the sun gear ring 16, and the guide ring 17 is coaxially fixed above the sun gear ring 16. An annular guide groove 175 is provided in the guide ring 17. The guide groove 175 includes an ascending section and a descending section. The ascending section and the descending section are connected end to end. The height position of the ascending section is higher than the height position of the descending section. The head and tail connection points of the ascending section and the descending section are respectively aligned with the rotating cylinder 23 and the arc-shaped blocking piece 331. A lifting and lowering inclined section is provided at the head and tail connection points of the ascending section and the descending section. The ascending section is used to guide the tightening structure 15 to raise its position to release the medicine bottle and keep the tightening structure 15 at the height position after raising. The descending section is used to guide the tightening structure 15 to descend to press the medicine bottle, keep the tightening structure 15 at the height position after descending, and make the tightening structure 15 tighten the bottle cap of the medicine bottle. For example, the base plate 31 is located at the bottom of the arc-shaped conveying channel 34 and is formed with a side defect. The bottom edge of the rotating wheel disc 12 is convexly arranged in the side defect of the arc-shaped conveying channel 34. A positioning disc is formed at the bottom of each conveying groove 121. The surface of the positioning disc is flush with the surface of the bottom plate 25 and the surface of the base plate 31. The circumference of the rotating wheel disc 12 is connected with the side of the base plate 31. Specifically, each tightening structure 15 includes a rotating rod 151, a tightening cover 152, a driven gear 153 and a lifting block 154. The rotating rod 151 is rotatably mounted on the periphery of the power disk 13. The tightening cover 152 is fixedly connected to the bottom end of the rotating rod 151 and is aligned with the corresponding conveying groove 121. The tightening cover 152 is located below the power disk 13. The driven gear 153 is fixedly connected to the top of the rotating rod 151 and is located above the power disk 13. The driven gear 153 is meshed with the sun gear ring 16. The lifting block 154 is rotatably connected to the upper center of the driven gear ring through the rotating shaft 1545. The lifting block 154 is located above the power disk 13. A cross bar is protruding from one side of the lifting block 154. A locking bead is provided at the end of the cross bar. The locking bead is slidably set in the guide groove 175 of the guide ring 17 and is set in the guide groove 175 to prevent it from falling off.The medicine bottles transported to the conveying groove 121 by the feeding channel 20 are all covered with bottle caps, and the bottle caps are not tightened; or, the tightening screw cap 152 is provided with a bottle cap; when the driving member 11 drives the rotating wheel 12 to drive the medicine bottle in the conveying groove 121 to move in the arc conveying channel 34, the rotating wheel 12 drives the power disk 13 to rotate synchronously, and the lifting block 154 of the tightening structure 15, which is a part of the periphery of the power disk 13, enters the descending section of the guide groove 175, and then pushes the driven gear 153 to drive the tightening screw cap 152 to descend, so that the tightening The screw cap 152 is pressed against the bottle cap of the corresponding medicine bottle, and at the same time, the multiple driven gears 153 are rotated by the meshing force of the sun gear ring 16, thereby driving the multiple tightening screw caps 152 to rotate, and the bottle cap of the medicine bottle is tightened by the tightening screw cap 152. When the medicine bottle is transported to the arc-shaped blocking piece 331, the rising section of the guide groove 175 of the guide ring 17 drives the tightening structure 15 to rise, thereby making the tightening screw cap 152 detach from the medicine bottle to release the medicine bottle, so that the medicine bottle can be detached from the rotating wheel 12 and enter the discharge channel 30. By setting the tightening assembly 10, the sun gear ring 16 can be used to drive the multiple driven gears 153 to rotate to implement the tightening operation, and the guide ring 17 can play a role of guiding up and down, thereby improving the tightening efficiency. The tightening assembly 10 realizes the automated operation of tightening the bottle cap, and the tightening assembly 10 has a simple structure and a single power, which saves costs. For example, in order to facilitate a certain buffering effect, a plurality of blind grooves are concavely provided on the bottom surface of the power disk 13, and a plurality of rotating rods 151 are inserted into the plurality of blind grooves. A buffer spring is sleeved on each rotating rod 151, and the buffer spring is partially accommodated in the blind groove. One end of the buffer spring abuts against the top surface of the blind groove, and the other end abuts against the top surface of the tightening cover 152. By providing a buffer spring, the stability of the tightening assembly 10 during the tightening operation can be improved.
