Description

Technical Field

[0001] The utility model relates to the field of filling machines, in particular to a turntable lifting mechanism in a large bottle filling machine. Background Art

[0002] In a large bottle filling machine, the filling valves are evenly distributed on the upper turntable on the upper side of the turntable, and the bottle holders are evenly distributed on the lower turntable on the lower side of the turntable. Each bottle holder corresponds to a filling valve up and down. The upper turntable and the lower turntable are connected by a number of vertical rods. The bottle holder is slidably connected to the guide sleeve on the lower turntable through the lower guide rod. A side guide sleeve is also provided on the bottle holder, and the side guide sleeve sliding sleeve is provided on the vertical rod. A cam ring in an inclined state is provided on the outer side of the lower turntable, and a guide wheel is provided on the lower guide rod. The guide wheel is rollingly clamped in the cam ring. When the turntable rotates, it will rotate with the upper turntable and the lower turntable. The bottle holder will rise and fall during the rotation process under the cooperation of the guide wheel and the cam ring. During the rising process of the bottle holder, the bottle on the bottle holder will abut against the corresponding filling valve to push the filling valve open, and the filling valve will fill the bottle. After the filling is completed, it will descend during the rotation process. During the descent process, it will be received by the receiving mechanism to the capping mechanism for capping.

[0003] Since the bottles filled by the large bottle filling machine are relatively large, the bottle will be filled with liquid and will exert a heavy weight on the bottle holder. During the lifting process of the bottle holder, it is easy for the lower guide rod and the guide sleeve, as well as the side guide sleeve and the vertical rod to wear. After the wear occurs, the guiding function of the guide sleeve and the side guide sleeve will be reduced, which will not only easily cause eccentricity between the bottle in the bottle holder and the filling valve, resulting in failure to fill or leakage during filling, but also easily cause the side guide sleeve and the vertical rod to get stuck, resulting in the lifting of the bottle holder. In order to prevent the above problems, it is necessary to replace the side guide sleeve and the guide sleeve regularly. Since the side guide sleeve is connected to the vertical rod, and the vertical rod is an important component that connects the upper turntable and the lower turntable so that the upper turntable and the lower turntable rotate synchronously, when replacing the side guide sleeve, the vertical rod needs to be removed from between the upper turntable and the lower turntable before replacement, which is very inconvenient. Utility Model Content

The upper guide rod 42 is threadedly connected to the upper turntable 1. A wrench protrusion 421 is provided on the upper guide rod 42, and the upper guide rod 42 can be conveniently rotated with a wrench through the wrench protrusion 421. The bottom of the bottle holder 4 is limited and guided by the guiding structure in which the lower guide rod 23 and the copper guide sleeve 22 cooperate. The top of the bottle holder 4 is limited and guided by the guiding structure in which the upper guide rod 42 and the nylon guide sleeve 41 cooperate. After the upper and lower ends of the bottle holder 4 are limited and guided, the bottle holder 4 can be more stably guided.

[0016] When the upper turntable 1 and the lower turntable 2 in the turntable are rotating, the bolt bearing 233 on the lower guide rod 23 moves along the cam ring 31, and the bolt bearing 233, under the guiding action of the cam ring 31, causes the lower guide rod 23 to be lifted and lowered in the copper guide sleeve 22, thereby causing the bottle holder 4 to be lifted and lowered. The bottle holder 4 can be stably lifted and lowered under the guiding action of the upper guide rod 42 and the nylon guide sleeve 41. When the bottle in the bottle holder 4 is matched with the corresponding filling valve 11 for filling, the nylon guide sleeve 41 reduces the shaking of the bottle holder 4 by absorbing energy, thereby reducing the shaking wear between the nylon guide sleeve 41 and the upper guide rod 42, and the copper guide sleeve 22 and the lower guide rod 23, extending the service life and ensuring the guiding accuracy. When the copper guide sleeve 22 is worn, it only needs to be removed from the bottle holder 4 to replace the copper guide sleeve 22. When the nylon guide sleeve 41 is worn, it only needs to be screwed off the upper guide rod 42 from the upper turntable 1 to replace it.

[0017] A connecting rod 5 is arranged on the frame 1, an adjusting seat 51 is sleeved on the connecting rod 5, a first fixing bolt 52 is threadedly connected to the adjusting seat 51, the first fixing bolt 52 abuts against the connecting rod 5 to fix the adjusting seat 51, a connecting shaft 53 is rotatably arranged in the adjusting seat 51, a bottle guard plate 54 is arranged on the connecting shaft 53, a second fixing bolt 55 is threadedly connected to the adjusting seat 51, the second fixing bolt 55 abuts against the connecting shaft 53 to fix the connecting shaft 53, thereby fixing the bottle guard plate 54. 4 is fixed, and the bottle guard plate 54 is tangent to the bottle that is rotated to the highest position and contacts the filling valve 11. In this way, the bottle guard plate 54 can protect the bottle that is located at the highest position and contacts the filling valve 11 to prevent a large shaking amplitude during the filling process, and will not interfere with the rotation of the turntable. During the filling process, the bottle guard plate 54 can indirectly reduce the shaking of the bottle bracket 4 after reducing the shaking of the bottle, thereby effectively reducing the wear between the lower guide rod 23 and the copper guide sleeve 22, and the upper guide rod 42 and the nylon guide sleeve 41. The larger the size of the bottle, the larger the rotation radius, and the smaller the size of the bottle, the smaller the rotation radius. The distance between the bottle guard plate 54 and the turntable can be adjusted by rotating the angle of the adjustment seat 51, so that the bottle guard plate 54 can protect bottles of different sizes. When the bottle guard plate 54 plays a protective role on the bottle, it generally rests on the middle part of the bottle to better protect the bottle. The heights of bottles of different sizes are different, and the middle positions of the bottles are also different. The inclination of the bottle guard plate 54 can be adjusted by rotating the connecting shaft 53, so that the bottle guard plate 54 can rest on the middle parts of bottles of different sizes.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
