[0047] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0048] like Figures 1-9 As shown, this utility model provides a liquid medicine filling device with a clamping structure, including a chassis 1; a controller 14 is installed on the upper side of the chassis 1, a column 3 is welded to the upper side of the chassis 1, and a support seat 2 is welded to the top of the column 3; a fence bend 16 is welded to the upper side of the support seat 2, a reduction motor 17 is bolted to the center of the lower side of the support seat 2, a turntable 6 is installed on the motor shaft of the reduction motor 17, a baffle 5 is bolted to the upper side of the turntable 6; a medicine bottle 4 is placed on the upper side of the turntable 6; and a support frame 7 is also included. The system includes a compression spring 10, a insert plate 18, an adjusting rod 19, a support plate 20, and a return spring 21. The upright frame 7 is welded to the insert plate 18. A base plate 1 is bolted to the lower side of the upright frame 7. Two sets of protruding plates are arranged from top to bottom on the rear side of the upright frame 7. Each set of protruding plates has a through hole. A threaded rod 13 is rotatably connected to the through holes of the two sets of protruding plates of the upright frame 7. A sliding plate 12 is meshed with the outer side of the threaded rod 13. A support frame 9 is bolted to the front side of the sliding plate 12. A through hole is provided on the upper side of the support frame 9, and an injection nozzle 8 is inserted into the through hole of the support frame 9. The liquid outlet at the bottom of the injection nozzle 8 is screwed with a jet needle tube 11. A lifting motor 15 is bolted to the lower side of the lower convex plate of the support frame 7, and a threaded rod 13 is mounted on the motor shaft of the lifting motor 15. A sealing cap 24 is welded to the bottom of the compression spring 10, and the injection nozzle 8 is welded to the top of the compression spring 10. A support plate 20 is welded to the front end of the return spring 21, and a clamping block 23 is welded to the rear end of the return spring 21. The support plate 20 is welded to the support frame 7, and a long, through-slot is provided on the upper side of the support plate 20, serving as a guide. The front and rear ends of the support rod 22 are welded to the front and rear ends of the through groove of the support plate 20, respectively; the controller 14 is connected to the lifting motor 15 through a wire, and the controller 14 is connected to the reduction motor 17 through a wire; the adjusting rod 19 includes a push rod 1901, a threaded adjusting rod 1902 and an adjusting knob 1903; the outer side of the threaded adjusting rod 1902 is engaged with the push rod 1901, and the top end of the threaded adjusting rod 1902 is welded to the adjusting knob 1903; the insert plate 18 is provided with a through hole, and the push rod 1901 is inserted into the through hole of the insert plate 18.

[0049] In this invention, when filling the medicine bottle 4, if the bottle height is high, the adjusting knob 1903 is manually turned. The adjusting knob 1903 drives the threaded adjusting rod 1902 to rotate, extending the threaded adjusting rod 1902 out of the cylindrical structure of the pushing rod 1901, increasing the length of the adjusting rod 19, so that the sliding plate 12 contacts the adjusting rod 19 earlier to perform the pushing action of the clamping block 23. If the bottle height is low, the length of the adjusting rod 19 is shortened, so that the sliding plate 12 contacts the adjusting rod 19 later to perform the pushing action of the clamping block 23. Then, the external medicine delivery hose is screwed onto the liquid inlet end of the filling nozzle 8, and the controller 14 controls the deceleration motor. When machine 17 rotates, the reduction motor 17 drives the turntable 6 to rotate. The groove of the turntable 6 moves the medicine bottle 4 inside the curved guardrail 16 to directly below the dispensing nozzle 8. Then, the controller 14 controls the lifting motor 15 to drive the threaded rod 13 to rotate. Since the thread on the outer side of the threaded rod 13 meshes with the protruding threaded through hole of the sliding plate 12, the threaded rod 13 drives the sliding plate 12 to move downward along the through groove of the upright 7. The sliding plate 12 drives the support frame 9 to move downward. The support frame 9 drives the spray needle tube 11 screwed to the bottom of the dispensing nozzle 8 to move downward. The spray needle tube 11 passes through the mouth of the medicine bottle 4 and gradually penetrates into the inside of the medicine bottle 4. At this time, the sliding plate 12 presses the adjustment knob 190. The adjusting pressure rod 19, welded to the bottom end, pushes the push rod 1901 downward along the through hole of the insert plate 18. The bottom end of the push rod 1901 moves along the 45-degree inclined surface of the clamping block 23. The push rod 1901 pushes the clamping block 23 forward along the guide support rod 22 until the arc groove on the front side of the clamping block 23 contacts the outer side of the medicine bottle 4. At this time, the push rod 1901 moves to the lowest end of the inclined surface of the clamping block 23. The clamping block 23 and the baffle 5 clamp the medicine bottle 4. At this time, the injection needle tube 11 penetrates into the medicine bottle 4. The silicone gasket on the lower side of the sealing cap 24 adheres to the mouth of the medicine bottle 4 under the elastic force of the compression spring 10 to cover it and prevent... To prevent the medicine from splashing onto the outside of the medicine bottle 4, the filling nozzle 8 injects the medicine into the medicine bottle 4 through the spray needle tube 11. The air in the medicine bottle 4 is discharged from the small through hole of the sealing cap 24. After the medicine is filled, the lifting motor 15 drives the sliding plate 12 to rise through the threaded rod 13. At this time, the filling nozzle 8 and the spray needle tube 11 rise synchronously, the spray needle tube 11 and the sealing cap 24 are separated from the medicine bottle 4, and the sliding plate 12 is separated from the adjusting pressure rod 19. At this time, the return spring 21 pulls the clamping block 23 to move backward along the guide support rod 22. The clamping block 23 drives the adjusting pressure rod 19 to move upward through the 45-degree inclined plane. The clamping block 23 releases the medicine bottle 4, completing the filling work of the medicine bottle 4.
