[0027] As described in the background art, in the production of pharmaceuticals, after grinding raw materials into powder, it is necessary to mix multiple raw materials in a certain proportion, and preliminary raw material mixing mostly uses a screw mixer. The screw mixer drives the screw blades in the shell to rotate through a motor, thereby mixing multiple raw materials in the shell. However, the existing screw mixers require a long time to achieve uniform mixing of multiple raw materials, with relatively low mixing efficiency, and it is inconvenient to discharge the mixed materials.

[0028] Based on this, the inventor created a multi-raw material powder screw mixer for pharmaceuticals in this application to solve the above technical problems.

[0029] The features and performance of the present utility model will be further described in detail below with reference to the embodiments.

[0030] Please refer to Figures 1 to 3, A multi-material powder screw mixer for pharmaceutical use, comprising a main body 10 having a motor 11, screw blades 12 and a housing 13. Here, the part of the screw blade 12 located outside the housing 13 is a shaft, and the motor 11 drives the screw blade 12 by connecting to the shaft.

[0031] The screw mixer further includes a gas supply assembly 20, a base 30 and a telescopic assembly 40. A lower part of one end of the housing 13 away from the motor 11 is provided with an openable and closable discharge door 131. An upper part of the housing 13 is provided with an exhaust port 14, and a filter screen 141 is arranged at the exhaust port 14. For example, the discharge door 131 can be rotated to open and close, or can be detachably connected to the housing 13 to open the discharge door 131. The present invention is not limited thereto. Here, the exhaust port 14 is used to discharge the gas ejected from the jet head 121, and the raw materials are blocked by the filter screen 141.

[0032] A plurality of jet heads 121 are arranged on the surface of the screw blade 12. A gas supply channel is arranged inside the screw blade 12. A joint 122 is arranged on the screw blade 12 located outside the housing 13. The joint 122 is communicated with the plurality of jet heads 121 through the gas supply channel, and the gas supply assembly 20 is communicated with the joint 122. For example, the gas supply assembly 20 can be an air pump. One end of the main body 10 is rotatably connected to the base 30, the other end of the main body 10 is rotatably connected to the driving end of the telescopic assembly 40, the fixed end of the telescopic assembly 40 is rotatably connected to the base 30, and the telescopic assembly 40 is adapted to lift one end of the housing 13 close to the motor 11. For example, the telescopic assembly 40 can be a cylinder or a hydraulic cylinder, which can be selected according to the weight of the raw materials carried in the housing 13.

[0033] The screw mixer of the present invention includes a main body 10, a gas supply assembly 20, a base 30 and a telescopic assembly 40. During operation, a variety of raw materials to be mixed are poured into the housing 13. The gas supply assembly 20 is connected to the joint 122 of the screw blade 12. The pressurized gas provided by the gas supply assembly 20 sequentially passes through the joint 122 and the gas supply channel, and is ejected from the jet head 121. Then, driven by the motor 11, the screw blade 12 rotates. The rotation of the screw blade 12 mixes the variety of raw materials. The gas ejected from the jet head 121 causes the raw materials to form bubbles, which can make the variety of raw materials mix more evenly, and shorten the mixing time required, effectively improving the mixing efficiency. When the mixing is completed, the driving end of the telescopic assembly 40 is extended to lift the main body 10, so that the main body 10 tilts towards the discharge port at a certain angle, and opening the discharge door 131 can discharge the materials under the action of gravity, and the discharging is simple.

[0034] In another embodiment, the jet head 121 is disposed on a side of the spiral blade 12 away from the inner wall of the housing 13. Such an arrangement can avoid friction between the jet head 121 and the inner wall of the housing 13, and also facilitate cleaning and maintenance of the jet head 121. Preferably, the plurality of jet heads 121 are embedded in the surface of the spiral blade 12. Such an arrangement avoids protrusion and is not easily worn. Preferably, the jet direction of the jet head 121 is located in the radial direction of the spiral blade 12 and faces the center of the circle. In this way, the raw materials can be bubbled towards the central axis of the spiral blade 12, further improving the mixing uniformity.

[0035] In another embodiment, the discharge door 131 is fan-shaped and its center of the circle is located on the central axis of the spiral blade 12.

[0036] In another embodiment, a clamping block 31 is provided at the top of the base 30. When the housing 13 is kept horizontal, the housing 13 is clamped on the clamping block 31. In this way, when the main body 10 is in the mixing operation, the whole main body 10 is in a more stable state, and at the same time, the telescopic assembly 40 is protected.

[0037] The above are only the preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, and improvements made by those skilled in the art within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
