the position of the rod withdrawing section 752 is more backward than the position of the disk withdrawing section 732, so that the push rod slider 743 enters the rod withdrawing section 752 only after the tray slider 723 passes through and leaves the disk withdrawing section 372, and the push rod 74 is withdrawn only after the tray 72 leaves the box body 8, so that the tray 72 is prevented from dropping when exiting the box body 8, and the material is stopped by the push rod 74 and still stays in the box body 8.

According to the invention, the box body 8 is conveyed by the turntable 3, so that box taking, box opening and box placing are carried out synchronously, the box body 8 is continuously placed on the packaging conveyor belt 6, the tray 72 and the push rod 74 respectively move synchronously to keep alignment with the box body 8, and filling is carried out in the moving process, so that the packaging conveyor belt 6 is not required to be stopped for waiting, continuous operation can be carried out, the mechanical wear of the conveyor belt is less, and the efficiency is extremely high.

It should be understood that the above-mentioned embodiments are merely illustrative of the technical concept and features of the present invention, and are not intended to limit the scope of the present invention, which is defined by the following claims.
