[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] according to Figure 1-Figure 4 As shown, it includes a filling cylinder 1, a liquid injection port 11 is provided on the side surface of the filling cylinder 1 near the top, and an inclined surface 12 is provided on the inner wall of the bottom end of the filling cylinder 1 near the edge, a placement groove 13 is provided on the inner wall of the bottom end of the filling cylinder 1 near the middle, and a sealing ring 14 is installed inside the placement groove 13, a mounting cylinder 15 is installed in the middle of the bottom end of the filling cylinder 1, and threaded holes 16 are provided on both sides of the mounting cylinder 15 at the top of the filling cylinder 1.

[0021] The filling head 2 is screwed onto the inside of the mounting barrel 15, and mounting blocks 21 are installed on the side surfaces of the filling head 2 at both ends. A threaded groove is provided on the side surface of the filling head 2 near the top, and the bottom end of the filling head 2 is conical. The tops of the two groups of mounting blocks 21 are fitted with the bottom end of the filling barrel 1, and grooves are provided on both sides of the mounting blocks 21. The interior of the filling head 2 is hollow, and the inner diameter of the filling head 2 is adapted to the inner diameter of the sealing ring 14. The interior of the mounting blocks 21 is movably screwed with a screw 22, and the bottom end of the screw 22 is installed with a mounting disk 23. The outer diameter of the screw 22 is adapted to the inner diameter of the threaded hole 16, and one end of the screw 22 extends into the interior of the threaded hole 16 and is movably screwed therewith. A hand-held rod 24 is installed at the bottom end of the mounting disk 23.

[0022] The top of the filling barrel 1 is mounted with a mounting plate 3, and the inner wall of the top of the mounting plate 3 is mounted with an electric push rod 31. The bottom of the electric push rod 31 is mounted with a connecting rod 32, and the bottom of the connecting rod 32 is mounted with a piston plate 33. The outer diameter of the piston plate 33 is adapted to the inner diameter of the filling barrel 1. The piston plate 33 is positioned inside the filling barrel 1. A through hole is formed in the inner wall of the top of the filling barrel 1 near the connecting rod 32. One end of the connecting rod 32 passes through the through hole and penetrates the inner wall of the top of the filling barrel 1, extending into the interior of the filling barrel 1.

[0023] Before using the filling and sealing machine, it is necessary to install the top of the filling head 2 with the bottom of the filling cylinder 1. The specific operation is as follows: the user can take the mounting block 21 through the grooves on both sides of the mounting block 21 to take the filling head 2. After that, the user can align the top of the filling head 2 with the inside of the mounting cylinder 15 and rotate it, so that the filling head 2 can extend into the inside of the mounting cylinder 15 and be movably screwed therewith, so that the top of the filling head 2 can finally fit with the bottom end of the sealing ring 14, so that the top surfaces of the two sets of mounting blocks 21 can fit with the filling cylinder 1. The bottom ends of the filling heads 2 and 1 are fitted together. After that, the user can rotate the two sets of hand-held rods 24 in sequence, so that the corresponding mounting plates 23 and the corresponding screw rods 22 can rotate accordingly, so that the interior of the corresponding screw rods 22 can extend into the interior of the corresponding threaded holes 16 and be screwed together accordingly, thereby completing the installation between the filling head 2 and the filling barrel 1, so that the top end of the filling head 2 will be connected to the interior of the filling barrel 1. At this time, the setting of the sealing ring 14 can seal the connection between the filling barrel 1 and the filling head 2, thereby preventing the liquid from leaking out during the filling operation.

[0024] After that, the user can inject the medicine liquid into the interior of the filling barrel 1 through the liquid injection port 11. After the injection is completed, the user can start the electric push rod 31, so that under the starting action of the electric push rod 31, the connecting rod 32 can move downward, so that the piston plate 33 can move downward in the interior of the filling barrel 1, so that the medicine liquid in the filling barrel 1 can be filled into the interior of the ampoule bottle through the filling head 2.
