[0029] like Figures 1 to 3 As shown, in this embodiment, the powder dosing device includes: a container 10, a conduction section 20, a feed tank 30, a connecting pipe 40, a buffer tank 50 and a controller. The first end of the conduction section 20 is connected to the container 10, and the conduction section 20 is provided with a first control valve 21. The feed end of the feed tank 30 is connected to the second end of the conduction section 20, and a first detection device is provided in the feed tank 30. The first end of the connecting pipe 40 is connected to the discharge end of the feed tank 30, and a second control valve 41 is provided on the connecting pipe 40. The buffer tank 50 is arranged downstream of the feed tank 30, the feed end of the buffer tank 50 is connected to the second end of the connecting pipe 40, and a second detection device is provided in the buffer tank 50. The controller is connected to both the first detection device and the second detection device, and controls the opening and closing of the first control valve 21 and the opening and closing of the second control valve 41.

[0030] By applying the technical solution of this embodiment, the first end of the conducting section 20 is connected to the container 10, the second end of the conducting section 20 is connected to the feeding end of the supply tank 30, the conducting section 20 is provided with a first control valve 21, the supply tank 30 is provided with a first detection device, the first end of the connecting pipe 40 is connected to the discharging end of the supply tank 30, the second end of the connecting pipe 40 is connected to the buffer tank 50, the connecting pipe 40 is provided with a second control valve 41, the buffer tank 50 is provided with a second detection device, the controller is connected to both the first detection device and the second detection device and controls the opening and closing of the first control valve 21 and the second control valve 41. Through the above-mentioned arrangement, the powder in the container 10 can enter the supply tank 30 through the conducting section 20, the powder in the supply tank 30 enters the buffer tank 50 through the connecting pipe 40, and then is transported to the filling machine through the buffer tank 50. The first detection device can detect the powder in the feed tank 30, and the second detection device can detect the powder in the buffer tank 50. When the first detection device detects that there is too much powder in the feed tank 30, the controller can control the first control valve 21 to close, so that the powder in the container 10 cannot enter the feed tank 30. When the second detection device detects that there is too much powder in the buffer tank 50, the controller can control the second control valve 41 to close, so that the powder in the feed tank 30 cannot enter the buffer tank 50. In this way, automatic control can be achieved without manual operation, thereby ensuring accuracy and timeliness. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that powder feeding requires manual processing, thereby resulting in low production efficiency of milk powder filling.

[0031] like Figures 1 to 4 As shown, in this embodiment, the powder dosing device further includes a mounting frame 60, the container 10 is detachably mounted on the top of the mounting frame 60, and the conducting section 20 and the supply tank 30 are both connected to the mounting frame 60. The arrangement of the mounting frame 60 can make the positions of the conducting section 20, the supply tank 30 and the container 10 more stable and less prone to shaking or tipping.

[0032] like Figures 1 to 4 As shown, in this embodiment, the powder dosing device further includes a vibrating screen 70, which is disposed on the mounting frame 60 and between the conducting section 20 and the feed tank 30.

[0034] like Figures 5 to 7 As shown, in this embodiment, the cross-sectional area of ​​the base 71 gradually decreases in the direction from the top cover 72 to the base 71. The above arrangement makes it easy for the screened powder to enter the supply tank 30.

[0035] like Figures 1 to 4 As shown, in this embodiment, the mounting frame 60 includes a frame body 61 and a limiting frame 62 disposed on the top of the frame body 61, the limiting frame 62 includes a first vertical frame 621 and a second vertical frame 622 disposed at intervals and a connecting rod 623 connected between the first vertical frame 621 and the second vertical frame 622, and the container 10 is mounted between the first vertical frame 621 and the second vertical frame 622 and is limited by the connecting rod 623. The first vertical frame 621 and the second vertical frame 622 can limit the two sides of the container 10, and the connecting rod 623 can support the container 10 to prevent the container 10 from tipping over.

[0036] like Figures 1 to 4 As shown, in this embodiment, the cross-sectional area of ​​the conducting section 20 gradually decreases in the direction from the container 10 to the supply tank 30. The above arrangement can make the powder flow more easily, that is, more easily enter the vibrating screen 70.

[0037] like Figures 1 to 4 As shown, in this embodiment, the distance a between the first detection device and the bottom of the feed tank 30 and the height b of the feed tank 30 satisfy: 0.3≤a / b≤0.5. The above setting can ensure that there is a certain amount of surplus in the feed tank 30, so that a certain amount of time can be provided to the buffer tank 50, and a certain amount of time can be reserved for the filling shutdown to avoid the problem of failure to fill.

[0038] Specifically, in this embodiment, a / b=0.4. Of course, in other embodiments, a / b may also be 0.35, 0.45 or other ratios.

[0039] like Figures 1 to 4 As shown, in this embodiment, the distance c between the second detection device and the bottom of the buffer tank 50 and the height d of the buffer tank 50 satisfy: 0.4≤c / d≤0.6. The above arrangement can also ensure that there is a certain amount of powder in the buffer tank 50, thereby achieving continuous feeding for a certain period of time.

[0040] According to another aspect of the present application, a milk powder filling system is provided. The milk powder filling system of this embodiment includes a powder adding device, and the powder adding device is the above-mentioned powder adding device.

Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0043] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0044] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
