Technical Field

[0001] The invention relates to the technical field related to filling, in particular to a variable-diameter star wheel transmission mechanism for a filling machine. Background Art

[0002] Filling is a key process in the production of carbonated beverages. Common filling methods include the typical double filling method and the single filling method, and sometimes a combined filling method is also used.

[0003] Disposable containers and new glass bottles generally do not need to be sterilized, and only need to be sprayed with sterile water for filling. For recycled glass bottles that are used multiple times, they need to be scrubbed and disinfected with special detergents and disinfectants. After washing, the glass bottles must be clean and odorless inside and out, without residual alkali and other detergents, and must pass the microbiological test. The washed bottles are directly dried on the bottle washing machine, or placed on a dripping car to drip out the remaining water in the bottles. Bottle inspection usually uses the naked eye inspection method. Bottles that pass the inspection are sent to the filling machine for filling by a transmission mechanism.

[0004] The transmission mechanism is generally a star-shaped structure, but the outer diameter of the existing star wheel transmission mechanism is fixed, which cannot meet different filling requirements and has a limited scope of application. Summary of the invention
