[0011] Preferably, the section of the pneumatic pipe communicated with the filling pipe is arranged in parallel with the diversion plate, and the lower side of the inner wall of the pneumatic pipe is tangent to the upper surface of the diversion plate.

[0012] Through the above technical solutions, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, a feeding ball is provided at the lower part of the filling pipe. The feeding ball is rotationally and sealingly fitted to the lower part of the filling pipe. When the feeding ball rotates, the moisture-sensitive powder in the feeding groove will be sent out from the material bin. At the same time, a sealed state is always maintained between the outer wall of the feeding ball and the inner wall of the filling pipe, and air cannot enter the material bin, thus preventing the moisture-sensitive powder in the material bin from getting damp.

[0020] In the description of the present utility model, it should also be noted that, unless otherwise clearly defined and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1:

[0023] As Figures 1-5As shown in the figure, a filling device for packaging moisture-sensitive fine powder particles is provided at the lower end of a storage bin 1. It is characterized in that the filling device includes a filling pipe 2 and a feeding ball 3. The filling pipe 2 is vertically arranged and its upper end is connected to the lower end of the storage bin 1. The feeding ball 3 is hermetically and rotationally fitted into the lower part of the filling pipe 2.

[0024] The feeding ball 3 is spherical and a plurality of concave feeding grooves are arranged in an array on its outer wall. The length value of the section of the feeding ball 3 fitted into the filling pipe 2 is greater than the diameter value of the upper end of the feeding groove.

[0025] When the feeding ball 3 rotates, the moisture-sensitive powder in the feeding groove will be sent out from the storage bin 1. At the same time, a sealed state is always maintained between the outer wall of the feeding ball 3 and the inner wall of the filling pipe 2, and air cannot enter the storage bin 1, thus preventing the moisture-sensitive powder in the storage bin 1 from getting damp.

[0026] In order to optimize the product structure, in this embodiment, the filling device further includes a deflector 4. The deflector 4 is fixedly arranged in the filling pipe 2 and above the feeding ball 3. The deflector 4 is inclined, with its upper end connected to the inner wall of the deflector pipe and its lower end facing the middle of the deflector pipe.

[0027] In order to prevent excessive accumulation of moisture-sensitive powder below the deflector 4 from causing blockage, the filling device further includes a return plate 5. The return plate 5 is arranged in parallel and at intervals below the deflector 4, and a number of through holes are evenly distributed on the return plate 5.

[0028] In order to improve the filling rate, the filling device further includes a pneumatic pipe 6.
