[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 This utility model provides a technical solution:

[0023] An antibacterial coating sprayer for the inside of a milk powder can includes a base 1. The interior of the base 1 is a central control structure. Two sliding grooves 11 are symmetrically opened on the top of the base 1 near the left and right sides to limit the movement direction of the slider 16. Both sliding grooves 11 are connected to the interior of the base 1. A placement groove 12 is opened on the top of the base 1 near the middle to place the milk powder can.

[0024] In a preferred embodiment, an adjusting motor 13 is fixedly connected to the inner left side wall of the base 1 by bolts to drive the bidirectional threaded rod 14 to rotate. The output shaft of the adjusting motor 13 is coaxially connected to the bidirectional threaded rod 14, and the other end of the bidirectional threaded rod 14 is rotatably connected to the inner right side wall of the base 1. The bidirectional threaded rod 14 has threads with opposite directions near the left and right sides, so that when the bidirectional threaded rod 14 rotates, the two moving plates 15 can move in opposite directions.

[0025] Specifically, two movable plates 15 are symmetrically threaded near the left and right sides of the bidirectional threaded rod 14 to drive the slider 16 to move. The top of the movable plate 15 is fixedly connected to the slider 16 by bolts. The bottom of the slider 16 is slidably connected to the inner wall of the groove 11 corresponding to its position to drive the movable seat 17 to move.

[0026] Specifically, each of the two sliders 16 has a movable seat 17 fixedly connected to its two sides that are close to each other, which is used to drive the arc-shaped clamp 18 to move. Each of the two movable seats 17 has a mounting groove 171 on its two sides that are close to each other.

[0027] Specifically, an arc-shaped clamp 18 is glued to the inner wall of the mounting groove 171. The arc-shaped clamp 18 is made of rubber and is used to fix the milk powder can.

[0028] It should be added that a U-shaped mounting bracket 19 is fixedly connected to the top of the base 1 by bolts to support and fix the hydraulic cylinder 21.

[0029] Furthermore, a spraying mechanism 2 is provided above the base 1. The spraying mechanism 2 includes a hydraulic cylinder 21, which is used to drive the moving frame 22 to move. The hydraulic cylinder 21 is fixedly connected to the top of the U-shaped mounting frame 19 by bolts. The piston rod end of the hydraulic cylinder 21 slides through the top of the U-shaped mounting frame 19 and is fixedly connected to the moving frame 22, which is used to drive the rotating tube 26 to move.

[0030] Specifically, a drive motor 23 is fixedly connected to the top of the inner wall of the movable frame 22 by bolts, which drives the gear 24 to rotate. The output shaft of the drive motor 23 is vertically downward and coaxially connected to the gear 24, which drives the gear ring 25 to rotate. A gear ring 25 that meshes with the gear 24 is provided on the right side, which drives the rotating tube 26 to rotate.

[0031] Specifically, a rotating tube 26 is welded and fixed to the inner side of the toothed ring 25. The bottom end of the rotating tube 26 extends through to the outer side of the bottom of the movable frame 22 and is rotatably connected to the movable frame 22 through a bearing, which is used to drive the nozzle 27 to rotate.

[0032] Specifically, two nozzles 27 are symmetrically fixedly connected to the left and right sides of the bottom of the rotating tube 26. One end of the liquid inlet pipe of the nozzle 27 passes through the outer wall of the rotating tube 26 and enters the inner cavity of the rotating tube 26, which is used to coat the liquid onto the inner wall of the milk powder can.

[0033] Specifically, a connecting pipe 28 is inserted into the top of the rotating tube 26. The other end of the connecting pipe 28 extends through to the outside of the right end of the movable frame 22 and is connected to a telescopic pipe 29. The other end of the telescopic pipe 29 passes through the top of the U-shaped mounting frame 19 and is fixedly connected to the U-shaped mounting frame 19. It is used to connect to the external antibacterial coating liquid feed pipe. The telescopic pipe 29, the connecting pipe 28, the rotating tube 26 and the nozzle 27 are connected in sequence.

[0034] In practical use, the user first places the milk powder can into the placement slot 12, turns on the adjusting motor 13, and the adjusting motor 13 drives the bidirectional threaded rod 14 to rotate, thereby driving the two moving plates 15 to move closer to the milk powder can, which in turn drives the two sliders 16 to move closer to the milk powder can, which in turn drives the two moving seats 17 to move closer to the milk powder can, which in turn drives the two arc-shaped clamps 18 to move closer to the milk powder can, until the inner surfaces of the two arc-shaped clamps 18 are tightly attached to the outer wall of the milk powder can. At this time, the position of the milk powder can is fixed. After turning off the adjusting motor 13, the antibacterial coating can be applied.

[0035] Next, the hydraulic cylinder 21 is activated to drive the moving frame 22 downwards, so that the bottom of the rotating tube 26 is inserted into the inside of the milk powder can. At this time, the two nozzles 27 are located inside the milk powder can. The drive motor 23 is activated to drive the rotating tube 26 to rotate, so that the two nozzles 27 rotate while spraying antibacterial coating onto the inner wall of the milk powder can. Moreover, the external antibacterial coating liquid inlet pipe connected to the connecting pipe 28 supplies coating liquid to the inside of the rotating tube 26.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
