[0057] In one embodiment, the third driving member 322 is electrically connected with the controller, and the controller can control the operation of the third driving member 322 according to needs. Specifically, when the controller controls the second driving member 5 to drive the tablet adding assembly 32 to move to the target position, at this time, the tablet through hole on the support table 33 is collinear with the center line of the target digestive tube 12 placed in the digestive tube clamping hole below, the controller controls the third driving member 322 to drive the tablet in the tablet storage cylinder 321 to move, so that it falls into the digestive tube 12 placed in the digestive tube clamping hole below through the tablet through hole.

[0058] In one embodiment, the tablet adding assembly 32 further comprises a pipe 323, the outer diameter of the pipe 323 is matched with the inner diameter of the tablet through hole, and the pipe 323 is clamped in the tablet through hole. In one embodiment, the middle part of the pipe 323 in the height direction is provided with a clamping table abutting against the top surface of the support table 33, for limiting the position of the pipe 323. The side wall of the pipe 323 close to the tablet storage cylinder 321 is provided with a tablet inlet, and the tablet inlet is corresponding to the opening on the tablet storage cylinder 321, that is, the center line of the tablet inlet is collinear with the center line of the opening. The controller controls the third driving member 322 to drive the tablet to leave the tablet storage cylinder 321 through the opening, and then the tablet enters the pipe 323 through the tablet inlet, and falls into the digestive tube 12 under the guidance of the pipe 323, preventing the tablet from deviating during falling.

[0059] In one embodiment, the tablet storage cylinder 321 and the third driving member 322 are both multiple, such as 2, 3, 5, etc. The third driving member 322 drives the tablet in the corresponding tablet storage cylinder 321 to fall into the digestive tube 12 through the tablet through hole, so that the tablet can be continuously added to the digestive tube 12 placed in the digestive tube clamping hole, avoiding long-term interruption.

[0060] In the case that the pipe 323 is clamped in the tablet through hole, the pipe 323 is provided with multiple tablet inlets, and the number of the tablet inlets is greater than or equal to the number of the tablet storage cylinders 321. Each tablet inlet is corresponding to the opening on one tablet storage cylinder 321, and the tablets in different tablet storage cylinders 321 can enter the pipe 323 through the corresponding tablet inlets, and then fall into the digestive tube 12 placed in the digestive tube clamping hole under the guidance of the pipe 323.

[0061] The milk tablet storage cylinder 321 comprises a fixed cylinder 3211, a sealing cylinder and an inner cylinder 3212. The fixed cylinder 3211 is installed on the support table 33, the sealing cylinder is inserted into the fixed cylinder 3211, and the inner cylinder 3212 is inserted into the sealing cylinder. The lower part of the fixed cylinder 3211, the sealing cylinder and the inner cylinder 3212 are all provided with openings, and the third driving end can drive the milk tablets to leave the milk tablet storage cylinder 321 through the openings in sequence. Specifically, the sealing cylinder and the inner cylinder 3212 are fixed on the support table 33 through the fixed cylinder 3211, the sealing cylinder is arranged between the inner cylinder 3212 and the fixed cylinder 3211, and is used for preventing the debris of the milk tablets from entering the fixed cylinder 3211. In the case of needing to clean and store the milk tablets, the sealing cylinder and the inner cylinder 3212 can be taken out alone or simultaneously, which is convenient for repeated use and is also helpful for maintenance.

[0062] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
