Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of filling medicine bottle capping, especially to a filling bottle cap screwing device. BACKGROUND

[0002] The medicine bottle needs to be capped after filling with medicine, and the common capping operation is performed by a cap screwing device, which generally comprises a conveying track and a cap screwing assembly.

[0003] The existing cap screwing device generally first arranges the bottle caps by a cap arranging machine, then conveys the bottle caps to the cap screwing assembly through a conveying track, simultaneously conveys the medicine bottles to the cap screwing assembly through another conveying track, and then drops the bottle caps onto the medicine bottles at the end of the conveying track, and finally starts the cap screwing assembly to screw the bottle caps. However, the bottle caps directly fall on the bottle body of the medicine bottle after passing through the conveying track, and at this time, the bottle caps only have a contact relationship with the top end of the medicine bottle. When the center point of the top end of the medicine bottle deviates from the bottle cap, the bottle cap will vibrate and deviate from its position with the movement of the conveying track, resulting in misalignment between the bottle cap and the thread on the bottle body. When the cap screwing device screws the bottle body, the misaligned bottle cap not only cannot seal the bottle body, but also damages the bottle body. Meanwhile, the deviation of the bottle cap position during transportation will cause the failure of the cap screwing work.

[0004] In related technologies, a medical medicine bottle cap screwing device is disclosed in Chinese Patent Publication No. CN111908397A, which reduces the probability of misalignment between the bottle cap and the bottle body by setting components such as a positioning assembly, a supporting assembly, a conveying assembly, a separating assembly, a hydraulic telescopic part, a rotating part, a connecting device, and a cap screwing device.

The pressure tablet (52) is connected to the cap conveying track (2) through a second torsion spring (231). The lower surface of the pressure tablet (52) abuts against the bottle cap and is used to pre-press the bottle cap onto the medicine bottle.

5. A bottle capping device according to claim 4, characterized in that: The tablet (52) has a first inclined surface (521), a second inclined surface (522), and a horizontal surface (523). The first inclined surface (521) is located above the clamp (51) and extends downward at an inclined angle. The first inclined surface (521) and the clamp (51) have the same inclination angle. The bottom end of the first inclined surface (521) is flush with the bottom end of the cap conveying track (2). The second inclined surface (522) is located at the bottom end of the first inclined surface (521) and extends downward at an inclined angle. The inclination angle of the second inclined surface (522) is greater than the inclination angle of the first inclined surface (521). The horizontal surface (523) is located at the bottom end of the second inclined surface (522) and extends horizontally above the rotating disk (32). The distance between the horizontal surface (523) and the rotating disk (32) is greater than the distance between the top of the medicine bottle and the rotating disk (32) and less than the sum of the height between the top of the medicine bottle and the rotating disk (32) and the height of the cap. The capping component (33) is located at the rear end of the second inclined surface (522).

6. A bottle capping device according to claim 3, characterized in that: The rotating disk (32) includes a first rotating disk (321) and a second rotating disk (322). The first rotating disk (321) is coaxially rotatably mounted on the base (31). The second rotating disk (322) is coaxially mounted on the first rotating disk (321) and located between the first rotating disk (321) and the capping component (33). The opening (35) includes a first slot (351) located on the first rotating disk (321) and a second slot (352) located on the second rotating disk (322). The first slot (351) cooperates with the limiting ring (34) to limit the body of the medicine bottle. The second slot (352) corresponds one-to-one with the first slot (351). The second slot (352) is located below the support ring of the neck of the medicine bottle.

7. A bottle capping device according to claim 6, characterized in that: The second turntable (322) is detachably mounted on the first turntable (321) via a connecting component (4).

8. A bottle capping device according to claim 7, characterized in that: The connection component (4) includes: Multiple connecting rods (41) are fixed on the upper surface of the first turntable (321) and extend vertically upward. The lower surface of the second turntable (322) has multiple connecting grooves (323) corresponding to the connecting rods (41). The connecting rods (41) are inserted into the corresponding connecting grooves (323). A connecting plate (42) is sleeved on a plurality of connecting rods (41). When the connecting rods (41) are inserted into the connecting grooves (323), the second turntable (322) abuts against the connecting plate (42). The connecting plate (42) is provided with bolts (421). The bolts (421) pass through the second turntable (322) and are threaded onto the connecting plate (42).
