[0002] In the process of producing and packaging using a penicillin bottle, it is necessary to unpack the penicillin bottle packaging containing empty penicillin bottles, and then move the penicillin bottle group in the packaging to the next processing area. During the movement of the penicillin bottle group, a clamp is generally used to fix the penicillin bottle group. The existing clamp generally inserts an air bag into the bottle, inflates the air bag inside to make it expand and contact the inner wall of the bottle (the air bag cannot be removed from the bottle), and fixes the bottle on the clamp. However, the inflation and expansion of the air bag for fixing has certain limitations. For example, when the air bag is broken, inflation cannot make the air bag expand, which results in that the air bag cannot be used, and reduces the service life of the air bag. SUMMARY

[0025] In this embodiment, as a further optimized scheme, please refer to Figure 6 The inside of the expansion ball 83 is empty, so that the expansion ball 83 can be more easily deformed when the movable sleeve 82 extrudes the expansion ball 83.

[0026] It should be noted that the working mode of the composite bottle group clamping mechanism is that the driving mechanism 2 works to move the mounting frame 3 on the guide rail 1, move the support 5 above the bottle group, and make the bottle expanding assembly 8 above the bottle opening of the bottle group; then the lifting cylinder 4 works to drive the support 5 to move downward, and the bottom end of the guide rod 81 is inserted into the bottle (so that the expansion ball 83 is in the bottle); the lifting cylinder 4 stops working, and the driving part 6 drives the pressing part 7 to move downward, pushes the movable sleeve 82 downward, extrudes the expansion ball 83, makes it deform and contact with the bottle wall, and fixes the bottle on the bottle expanding assembly 8; then the lifting cylinder 4 can move upward with the support 5 and the bottle group, and the mounting frame 3 can be moved horizontally through the driving mechanism 2, so that the fixed bottle group can be moved.

[0027] It should be further noted that the number of the bottle expanding assembly 8 can be adjusted according to the number of the bottle group, and the size of the bottle expanding assembly 8 can also be adjusted according to the specification of the bottle group.

[0028] In this embodiment, as a further optimized scheme, please refer to Figure 4 , the support 5 includes two mounting plates 51 and a support rod 52 mounted between the two mounting plates 51, and the guide rod 81 is mounted at the bottom of the lower mounting plate 51; the pressing part 7 includes a moving plate 71 slidably mounted on the support rod 52, and the bottom of the moving plate 71 is provided with a connecting rod 72, the bottom end of the connecting rod 72 extends to the bottom of the lower mounting plate 51 and is connected with a pressing plate 73, the pressing plate 73 is provided with a through hole for the guide rod 81 to pass through, the bottom of the pressing plate 73 is attached to the top wall of the movable sleeve 82, and the moving end of the driving part 6 is connected with the moving plate 71; when the driving part 6 drives the moving plate 71 to move, the connecting rod 72 will move with the pressing plate 73.

[0029] In this embodiment, as a further optimized scheme, please refer to Figure 4 , the guide rod 81 is detachably mounted on the lower mounting plate 51; the connection between the guide rod 81 and the lower mounting plate 51 can be disconnected, which is used to detach the bottle expanding assembly 8 from the support 5, so that the bottle expanding assembly 8 can be replaced.

[0030] In this embodiment, as a further optimized scheme, please refer to Figure 5 , the base 84 is in the shape of a circular truncated cone, and the diameter of the base 84 gradually decreases from top to bottom; which is convenient for the base 84 to enter the bottle.

[0031] In this embodiment, as a further optimized scheme, please refer to Figure 1 and Figure 3The push plate 10 is arranged on the lower mounting plate 51 and is below the pressing piece 7 (the push plate 10 is below the pressing plate 73), and the push plate 10 is provided with a through hole for the guide rod 81 and the movable sleeve 82 to pass through; when the lifting cylinder 4 is lowered with the bracket 5 and the bottom end of the guide rod 81 is inserted into the bottle, the bottom of the push plate 10 will contact the top of the bottle, so as to limit the lower position of the bracket 5 and ensure the accuracy of the insertion of the guide rod 81 into the bottle.

[0032] In this embodiment, as a further optimized scheme, please refer to Figure 1 and Figure 3 The push plate 10 is provided with a connecting frame 9, the connecting frame 9 is slidingly mounted on the mounting frame 3, and the moving direction of the connecting frame 9 is the same as that of the bracket 5; the bracket 5 is provided with a driving cylinder 11, the moving end of the driving cylinder 11 is provided with a latch 12, the connecting frame 9 is provided with a plug hole 13, the latch 12 is inserted into the plug hole 13, and the push plate 10 is limited and fixed by the latch 12; when the lifting cylinder 4 is raised with the bracket 5 and the bottle expander assembly 8 is moved out of the bottle, the driving cylinder 11 works, the latch 12 is moved out of the plug hole 13, and the push plate 10 is limited; under the action of gravity, the push plate 10 is lowered (the push plate 10 is not raised with the bracket 5), which has a blocking effect and prevents some bottles from being lifted by the bottle expander assembly 8, thereby achieving a safety protection effect.

[0033] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
