The bottle body positioning and clamping mechanism 7 is installed on the rotating plate 2 and is used for clamping the filling bottles. The ring track plate 10 is installed on the fixed stand 3 and is used for controlling the filling and lifting of the filling and capping mechanism 9. Teeth matching with the filling and capping mechanism 9 are provided on the circumferential surface of the ring track plate 10.

[0029] Among them, the medicine bottles are transported into the working area below the filling and capping mechanism 9 by a belt conveyor, and the bottle caps are gradually transported to the bottle cap supply mechanism 6 through the loading tray. The belt conveyor and the bottle cap supply mechanism 6 are existing technologies and will not be described in detail here; the lower side of the annular track plate 10 is wavy, and the wavy shape has two convex arc surfaces and two concave arc surfaces. Among the two convex arc surfaces, one is used to control the descending distance of the working end of the filling and capping mechanism 9 for filling, and the other is used to control the descending distance of the filling and capping mechanism 9 to tighten the bottle cap, and the concave arc surface will cause the working end of the filling and capping mechanism 9 to rise and fall off the bottle cap or the filling bottle mouth.

[0030] Specifically, the power device drives the rotating tube 4 to rotate, and the rotating tube 4 drives the rotating plate 2 to rotate. Several filling and capping mechanisms 9 on the rotating plate 2 rotate around the rotating tube 4 along with the rotating plate 2. When the filling and capping mechanism 9 rotates, its working end will move up and down along the wave surface on the lower side of the annular track plate 10, and the wave surface is used to control the working end of the filling and capping mechanism 9 to rise and fall. At the same time, the teeth on the circumferential surface of the annular track plate 10 are used to control the rotation of the working end of the filling and capping mechanism 9 to provide power for the working end to tighten the bottle cap; the medicine bottle being transported is clamped and fixed by the bottle body positioning and clamping mechanism 7 to ensure stability during filling and capping, and the bottle cap is transported to the bottle cap feeding mechanism 8 by the bottle cap supply mechanism 6, and the bottle cap is transported to the bottom of the working end of the filling and capping mechanism 9 by the bottle cap feeding mechanism 8 and positioned, and finally the bottle cap is tightened on the medicine bottle by the working end of the filling and capping mechanism 9.

[0031] In another embodiment of the present invention, the filling and capping mechanism 9 includes a filling fixed plate 91, a lifting slide bar 92, a lifting spring 93, a lifting frame 94, a filling tube 95, a bottle cap clamp 96, a gear 97, a gear ring 98 and a filling head 99. Several lifting slide bars 92 are connected to the filling fixed plate 91 and are slidably connected to the lifting frame 94. The lifting spring 93 is sleeved on the lifting slide bar 92 and is located between the lifting frame 94 and the filling fixed plate 91. The filling tube 95 is movably connected to the lifting frame 94 and the upper and lower ends are respectively connected to the bottle cap clamp 96 and the filling head 99. The gear 97 is movably connected to the lifting frame 94 and meshes with the teeth and gear ring 98 on the circumferential surface of the annular track plate 10. The gear ring 98 is sleeved on the filling tube 95. The lifting frame 94 is equipped with a lifting track wheel 910 that cooperates with the lower side of the annular track plate 10.

[0032] Specifically, when the filling fixed plate 91 is driven to rotate by the rotating plate 2, the lifting frame 94 is synchronously driven to make the lifting track wheel 910 thereon move along the wave surface on the lower side of the annular track plate 10. When the lifting track wheel 910 rolls to the top of the wave surface, the lifting frame 94 will be driven to descend, and the lifting frame 94 drives the gear 97 and the filling tube 95 to descend. When the lifting track wheel 910 rolls to the lower part of the wave surface, the lifting frame 94 rises under the action of the lifting spring 93, so that the gear 97 and the filling tube 95 are driven to rise, and the lifting frame 94 is driven to descend. When the gear 97 moves up and down, it is always in meshing state with the teeth on the side of the annular track plate 10, so that when the lifting frame 94 rotates around the rotating tube 4, the gear 97 will be driven to rotate by the teeth on the side of the static annular track plate 10, and the gear 97 then drives the gear ring 98 to rotate the filling tube 95; in the filling state, the filling tube 95 moves downward to the mouth of the medicine bottle for filling, and in the capping state, the filling tube 95 descends and the filling head 99 on it clamps the main bottle cap, pressing the bottle cap at the bottle mouth, and the rotating filling tube 95 provides torque to tighten the bottle cap.

[0033] In another embodiment of the present invention, the bottle cap feeding mechanism 8 includes a fixed bottle cap conveying device and a dynamic bottle cap conveying device, the fixed bottle cap conveying device is installed on the fixed frame 1, and several of the dynamic bottle cap conveying devices are installed on the rotating plate 2 and cooperate with the corresponding filling and screwing cap mechanism 9, and an arc plate that cooperates with the fixed bottle cap conveying device is connected between adjacent dynamic bottle cap conveying devices; the fixed bottle cap conveying device includes a conveying pipe 81, a spring 83, a positioning ring 84, a feeding block 85, a pushing rod 87, a bottle cap spring 89, a conveying inclined block 810 and a roller 811, and the conveying pipe 81 is connected to the fixed frame 1.

[0034] Specifically, the bottle caps are sequentially conveyed to several movable bottle cap conveying devices by the fixed bottle cap conveying device, and the bottle caps on the fixed bottle cap conveying device are blocked by the arc plate to prevent the bottle caps from being displaced due to the negative pressure of the airflow generated by the operation of the equipment when the next movable bottle cap conveying device is switched after the bottle caps on the fixed bottle cap conveying device are pushed once; the bottle caps are gradually conveyed into the conveying pipe 81 by the bottle cap supply mechanism 6, and the bottle caps after entering are positioned by the cooperation of at least two of the elastic sheets 83, which play a supporting role, and the elastic sheet 83 is fixed by inserting one end of the elastic sheet 83 between the positioning ring 84 and the conveying pipe 81, and then fixed by screws, and The other end of the spring piece 83 passes through the spring hole 82 and enters the conveying tube 81 to support and position the bottle cap. The bottle cap in the conveying tube 81 is gradually driven to rise and enter the conveying groove 86. When the conveying inclined block 810 is driven by the rotating plate 2 to move through the roller 811, the roller 811 will roll along the inclined surface of the conveying inclined block 810, and the roller 811 drives the pushing rod 87 to move. The other end of the pushing rod 87 pushes the bottle cap in the conveying groove 86, and then the bottle cap is pushed into the moving bottle cap conveying device, completing the effect of the fixed bottle cap conveying device rotating the bottle cap conveying device; after the bottle cap completes a single conveying, the roller 811 is driven to reset by the bottle cap spring 89.

[0035] In another embodiment of the present invention, a bottle cap conveying linear bearing 88 is included, and the push rod 87 is connected to the loading block 85 through the bottle cap conveying linear bearing 88; the end of the push rod 87 away from the conveying inclined block 810 is set to be square.

[0036] Specifically, the bottle cap conveying linear bearing 88 is used to ensure the smooth back and forth movement of the push rod 87 to avoid jamming. The end of the push rod 87 away from the conveying inclined block 810 is set to a square shape to prevent the push rod 87 from rotating, and its square part slides back and forth while penetrating the loading block 85.

[0037] In another embodiment of the present invention, the movable bottle cap conveying device includes a slide bar 812 and a bottle cap limiting block 814, the slide bar 812 is installed on the rotating plate 2 and one end is connected to the bottle cap limiting block 814, the slide bar 812 is provided with a slide groove 813 for the bottle cap to slide, the bottle cap limiting block 814 is penetrated by a bottle cap positioning hole 816 that cooperates with the bottle body positioning and clamping mechanism 7, and the bottle cap limiting block 814 is provided with a bottle cap sliding hole 815 connecting the bottle cap positioning hole 816 and the slide groove 813.

[0038] Specifically, after the bottle cap enters the slide groove 813, the bottle cap in the slide groove 813 is pushed into the bottle cap sliding hole 815, and the bottle cap in the bottle cap sliding hole 815 is pushed into the bottle cap positioning hole 816. The bottle cap that falls into the bottle cap positioning hole 816 is stuck by the filling head 99 and driven to rotate to tighten it on the bottle mouth.

[0039] In another embodiment of the present invention, the bottle cap supply mechanism 6 includes a power motor 61, a U-shaped fixing frame 62, a rotating shaft 63, a lower rotating plate 64, an upper rotating plate 65, a triangular track plate 66, a telescopic sliding column 67, a universal wheel 68, a linear bearing 69, a top plate 610 and an L-shaped bottle cap limiting ring 611.

A return spring is sleeved on the telescopic sliding column 67. The two ends of the return spring are respectively connected to the telescopic sliding column 67 and the fixing frame 1.

[0040] Specifically, the power motor 61 drives the rotating shaft 63 to rotate. The rotating shaft 63 drives the lower rotating plate 64 and the upper rotating plate 65 to rotate. The bottle cap is introduced into the bottle cap positioning groove 612 from the feeding groove by the feeding tray and is transmitted by the upper rotating plate 65. At the same time, the position of the bottle cap is limited by the cooperation of the L-shaped bottle cap limiting ring 611 and the bottle cap positioning groove 612, so that the bottle cap can stably rotate and move along with the upper rotating plate 65. When the triangular track plate 66 on the lower rotating plate 64 moves to the universal wheel 68, the universal wheel 68 will roll onto the triangular track plate 66, so that the universal wheel 68 drives the telescopic sliding column 67 to rise.

After the bottle cap completely enters the center of the conveying pipe 81, the spring telescopic rod restores its telescopic state to quickly push the bottle cap into the conveying pipe 81; after the bottle cap is pushed, the universal wheel 68 rolls out of the triangular track plate 66, and at the same time, the return spring and the spring telescopic rod instantaneously rebound to drive the telescopic sliding column 67 to descend and reset.

[0042] Specifically, through the convex and concave parts of the annular track 72, the convex and concave parts are shaped close to or away from the filling and capping mechanism 9. When the track wheel 73 rolls along the annular track 72, the track wheel 73 enters the convex part of the annular track 72, which will cause the track wheel 73 to drive the slide bar 74 to move, and the slide bar 74 drives the connecting plate 79. The connecting plate 79 pushes two symmetrical hinged rods 710. The two symmetrical hinged rods 710 push one end of a clamping plate 712 respectively, and the other ends of the two clamping plates 712 rotate along the hinge, so that the other ends are close to clamp and position the bottle body. Conversely, when the track wheel 73 enters the concave part of the annular track 72, the other ends of the two clamping plates 712 are loosened, thereby achieving the purpose of clamping and positioning the bottle body.

[0043] In another embodiment of the present invention, the bottle cap clamp 96 is slidably connected to the filling tube 95, and a twist cap spring is sleeved on the filling tube 95, one end of the twist cap spring is connected to the filling tube 95 and the other end is connected to the bottle cap clamp 96; the lower side surface of the annular track plate 10 is wavy, and a working stable surface 11 is provided at the wave crest of the wavy shape.

[0044] Specifically, the corresponding bottle cap is clamped by the bottle cap clamp 96, and the bottle cap clamp 96 is designed according to the structure of the bottle cap.
