Technical Field

[0001] The utility model relates to the technical field of filling and gas-charging equipment, in particular to a reciprocating bottle-feeding mechanism. Background Art

[0002] Filling is a part of industrial production. In the filling production line, the filled bottles need to be transported in an orderly manner. Compared with manual operation, the existing filling system often uses a conveyor belt for transportation, which has a higher degree of automation. For example, the aseptic liquid filling machine with patent application number 201420671011.8 includes a frame, and a conveying mechanism, a filling mechanism, a plugging mechanism and a plugging mechanism are arranged on the frame. The conveying mechanism transports the glass bottles to each station for filling and plugging. It has a high degree of automation, reduces labor intensity, and improves work efficiency. However, it puts forward higher requirements on the positioning accuracy of the conveying, requiring the glass bottles to be transported directly below each station.

[0003] In the aerosol filling process, since there are more workstations to be transported, the traditional linear bottle feeding mechanism cannot position the aerosol cans, and its positioning accuracy is poor, which cannot ensure that the aerosol cans are accurately transported to the bottom of each workstation and facilitate the normal operation of each workstation. Utility Model Content
