Full-automatic boar semen filling machine

The full-automatic boar semen filling machine comprises a base and a packaging bag, a shell is mounted at the top end of the base, a guide groove is formed in the top end of the shell, and a mounting plate is mounted on one side of the top of the shell; in the machining process, when a package penetrates through the space between the two grating assemblies, two shadow blocks at the top end of the packaging bag are scanned through the grating assemblies, and then the packaging bag is positioned; after positioning is completed, a third motor is matched with a third motor shaft to drive two clamping blocks to clamp the two ends of the packaging bag, then a second air cylinder pushes a movable sliding block to synchronously extrude the top end of the packaging bag inwards, at the moment, opening structures on the two sides of a feeding opening are matched, the feeding opening is temporarily expanded, and then a liquid injection pipe is conveniently inserted into the packaging bag; and the processing efficiency is
