[0026] Example

[0027] For easier understanding, see Figures 1 to 4The utility model provides an embodiment of an automatic feeding device for standard solution production, comprising a shell 1, a rotating groove is opened at the top of the shell 1, and a stirring assembly is arranged at the top of the shell 1; the stirring assembly comprises a rotating cylinder 5, a mounting cylinder 7, a mounting shaft 9, a plurality of movable grooves 10, a connecting plate 11, a plurality of first stirring rods 12 and a second stirring rod 13, the rotating cylinder 5 is rotatably mounted on the wall of the rotating groove, the mounting cylinder 7 is slidably mounted on the inner wall of the rotating cylinder 5, the mounting shaft 9 is fixedly mounted on the bottom end of the mounting cylinder 7, a plurality of movable grooves 10 are opened on the outer wall of the mounting shaft 9, the connecting plate 11 is slidably mounted on the inner wall of the mounting shaft 9, a plurality of first stirring rods 12 are rotatably mounted on the outer wall of the connecting plate 11, the second stirring rod 13 is rotatably mounted on one end of the first stirring rod 12, and the other end of the second stirring rod 13 is rotatably mounted on the bottom end of the groove wall of the corresponding movable groove 10.

[0028] It should be noted that the first stirring rod 12 and the second stirring rod 13 in the stirring assembly can extend or retract into the mounting shaft 9. When the first stirring rod 12 and the second stirring rod 13 are retracted into the mounting shaft 9, it is convenient to pull out the rotating cylinder 5, making it easier to disassemble the stirring assembly and to clean the stirring assembly. The stirring assembly is installed by setting the rotating cylinder 5 and the mounting cylinder 7, and the first stirring rod 12 and the second stirring rod 13 are controlled to open and retract by setting the connecting plate 11 inside the mounting shaft 9. The solution in the outer shell 1 is stirred and mixed by setting the first stirring rod 12 and the second stirring rod 13.

[0029] In some embodiments, as Figure 2 As shown, the position of the first stirring rod 12 corresponds to the movable groove 10, the first stirring rod 12 passes through the movable groove 10 and extends to the outside of the mounting shaft 9, a plurality of slots 6 are provided on the inner wall of the rotating cylinder 5, and a plurality of protrusions are integrally formed at the bottom end of the mounting cylinder 7, the protrusions are engaged with the corresponding slots 6, and the mounting cylinder 7 is fixed to the top of the rotating cylinder 5 by screws.

[0030] It should be noted that, in this example, two movable grooves 10 can be set, and the two movable grooves 10 are relatively arranged on the outer wall of the mounting shaft 9. When the electric push rod 8 is started, it drives the connecting plate 11 to move. When the connecting plate 11 moves downward, it drives the first stirring rod 12 and the second stirring rod 13 to rotate, so that the first stirring rod 12 and the second stirring rod 13 are expanded in a triangular shape. When the connecting plate 11 moves upward, the first stirring rod 12 and the second stirring rod 13 rotate until they are linearly retracted into the inside of the mounting shaft 9.

By setting the gear 16 and the gear ring 17 to drive the mounting cylinder 7 to rotate, the disassembly of the stirring assembly is not affected.

[0033] In some embodiments, as Figure 2 As shown, a number of mounting plates 2 are fixedly installed on the top of the outer wall of the shell 1, a container 3 is provided on the top of the mounting plate 2, a connecting pipe is fixedly installed on the top of the container 3, one end of the connecting pipe extends to the inside of the shell 1, a number of pump bodies 4 are fixedly installed on the inner wall of the shell 1, one end of the connecting pipe is connected to the inlet of the corresponding pump body 4, a delivery pipe 18 is fixedly installed on the bottom end of the inner wall of the shell 1, the bottom end of the delivery pipe 18 extends to the outside of the bottom end of the shell 1, and a solenoid valve 19 is fixedly installed on the bottom end of the delivery pipe 18.

[0034] It should be noted that the container 3 can be filled with a solution from the top opening, and the solution is transported to the inside of the housing 1 through the pump body 4. After the solution is mixed, the solenoid valve 19 is opened for loading.

[0035] The motor 15 and the electric push rod 8 in the present invention are well-known components and will not be described in detail here.

[0036] Working principle: When installing the stirring assembly, the electric push rod 8 starts to drive the connecting plate 11 to move.
