Detailed Embodiment

[0015] As Figures 1-3 shown, the present utility model provides a continuous filling device for medicine bottles, which includes a cylindrical chassis 1, a turntable 2 and a support disk 7 coaxially and rotatably arranged on the top of the chassis 1, and a feeding channel 3 and a discharging channel 4 connected to both sides of the chassis 1. The feeding channel 3 and the discharging channel 4 are respectively connected to a medicine bottle conveyor belt. Arc-shaped grooves adapted to the outer diameter of the medicine bottles are evenly arranged on the edge of the turntable 2. A gap for accommodating the medicine bottles is provided between the inner side wall of the arc-shaped groove and the inner side wall of the chassis 1. Nozzles 9 are arranged on the support disk 7 corresponding to the arc-shaped grooves. The nozzles 9 are arranged in parallel through shunt pipes 8 on a shunt disk 5 at the center of the support disk 7. The center of the top of the shunt disk 5 is connected to a liquid inlet pipe 6. The nozzles 9 are provided with a liquid outlet structure when the nozzles 9 rotate towards the discharging channel 4.

[0016] The medicine bottles are conveyed one by one into the chassis 1 through the conveyor belt of the medicine bottles. When the turntable 2 rotates, the medicine bottles enter the arc-shaped grooves. Then the medicine bottles can rotate in the chassis 1 with the turntable 2. At the same time, since the nozzle 9 is directly above the center of the arc-shaped groove and directly above the bottle mouth of the medicine bottle, during the process of driving the turntable 2 to rotate by the driving mechanism at the bottom, because the turntable 2 and the support plate 7 are coaxially fixedly connected through the central column, the medicine bottles and the nozzle 9 rotate synchronously. When the nozzle 9 touches the liquid outlet structure, the nozzle 9 starts to fill the medicine bottles, realizing continuous filling of multiple medicine bottles. According to the liquid outlet speed of the nozzle 9, the rotation speed of the turntable 2 is controlled, which can not only improve the filling speed but also control the filling volume. When the medicine bottles rotate close to the discharge channel 4, the nozzle 9 separates from the liquid outlet structure, the nozzle 9 stops filling, and the turntable 2 keeps rotating, moving the medicine bottles to the discharge channel 4, and the medicine bottles are sent out through the conveyor belt for discharging, realizing continuous filling.

[0017] As Figures 1-3 shown. The liquid outlet structure includes an insertion cylinder 13 with a spindle-shaped shell structure sleeved on the bottom of the nozzle 9. A push-type liquid outlet switch 12 is arranged on the side wall of the bottom end of the nozzle 9. An arc-shaped pressing piece 11 is inclined from the feed channel 3 towards the discharge channel 4. The insertion cylinder 13 is located inside the pressing piece 11 and contacts the bottom surface of the pressing piece 11. During the process of the support plate 7 rotating with the turntable 2, the top end of the insertion cylinder 13 sleeved on the nozzle 9 starts to contact the pressing piece 11. Initially, the insertion cylinder 13 is located below the pressing piece 11 and gradually contacts the pressing piece 11 during the rotation process. The pressing piece 11 presses down the insertion cylinder 13, and the inner side wall of the top of the insertion cylinder 13 presses the liquid outlet switch 12, and the nozzle 9 starts to discharge liquid to fill the medicine bottles. And the bottom end of the insertion cylinder 13 is inserted into the bottle mouth of the medicine bottle to ensure that the liquid medicine will not spill out, and after the nozzle 9 moves out of the pressing piece 11, the filling stops.

[0018] As Figures 2-3 shown. A spring is sleeved on the nozzle 9. The two ends of the spring are respectively fixedly connected to the nozzle 9 and the insertion cylinder 13. And when the top end of the insertion cylinder 13 contacts the middle bottom surface of the pressing piece 11, the spring is in a stretched state. When the nozzle 9 leaves the pressing piece 11, the spring drives the insertion cylinder 13 to reset. The spring pulls the insertion cylinder 13 upwards, so that the liquid outlet switch 12 loses pressure, and then the nozzle 9 is closed, and the nozzle 9 stops discharging liquid for filling. A ring-shaped connection disk 14 is fixedly connected to the top of the insertion cylinder 13, and contacts the pressing piece 11 through the connection disk 14. The pressing piece 11 is supported by the connection piece 15 on the chassis 1 to realize the stable installation of the pressing piece 11.

[0019] As a preferred embodiment of the present utility model. A spiral guide groove is provided on the inner side wall of the bottom end of the insertion cylinder 13, and the outer diameter of the bottom end of the insertion cylinder 13 is smaller than the inner diameter of the medicine bottle mouth. By providing a spiral guide groove in the insertion cylinder 13, the outflowing liquid medicine has a certain rotation direction, which can reduce the impact on the medicine bottle compared with the direct filling form.

[0020] As Figure 1 shown. An arc-shaped lever 10 is fixedly provided on one side of the discharge channel 4, and the thickness of the movable end of the lever 10 is smaller than the thickness of the fixed end. When the medicine bottle is about to move to the discharge channel 4, the medicine bottle contacts the movable end of the lever 10, and the lever 10 guides the medicine bottle so that the medicine bottle can smoothly enter the discharge channel 4; the design of the movable end of the lever 10 enables the lever 10 to have a certain elasticity and can better pick out the medicine bottle from the arc-shaped groove of the turntable 2.
