[0002] At present, there are two main ways of packaging bottle caps in China: bulk and arranged in boxes. Among them, the bulk packaging method is very likely to cause the bottle caps to be deformed and damaged due to mutual squeezing, and the packaging space utilization rate is low; in addition, most of the production lines used in the arranged box method adopt the method of vibration sorting and integrated boxing, that is, the bottle caps are randomly stacked on the conveying device, and the bottle caps are vibrated and arranged by the vibration device. In this process, the bottle caps are very likely to be deformed and damaged due to collision, the sorting efficiency is low, and material accumulation is easy to occur.
