[0020] As attached Figure 1 , Attachment Figure 2 The utility model is shown as an automatic feeding device for pharmaceutical use, which includes a base 1 and a vibration device. A horizontal conveying pipeline 2 is installed on the base 1. An inlet sealing plate 3 and an outlet sealing plate 4 for blocking the conveying pipeline 2 are installed at both ends of the conveying pipeline 2. A rotating shaft 5 is installed in the conveying pipeline 2 along the length direction. A spiral conveying blade 6 is connected around the rotating shaft 5. A feeding motor 7 for driving the rotating shaft 5 to rotate is installed on one side of the conveying pipeline 2, so that the conveying blade 6 transfers the material from the inlet sealing plate 3 to the outlet sealing plate 4. A driving pulley is installed at the output end of the feeding motor 7, and a driven pulley is installed on the part of the rotating shaft 5 extending to the outside of the inlet sealing plate 3, and a transmission belt is connected between the driving pulley and the driven pulley. A hopper 8 connected to the conveying pipeline 2 is installed above the side of the conveying pipeline 2 close to the inlet sealing plate 3, and the powdered material is introduced from the hopper 8 into the conveying pipeline 2. A transition pipe 9 connected to the conveying pipeline 2 is installed below one side of the conveying pipeline 2 close to the outlet sealing plate 4 , and the powdered material falls into the transition pipe 9 after being pushed by the conveying blades 6 .

[0021] A detachable outlet pipe 10 is installed at the end of the transition pipe 9. Figure 3 As shown, several spaced screens 11 are installed in the outlet pipe 10 in sequence along the direction of gravity to filter the powdered material, so as to avoid the material being blocked during feeding, the powder condensing into blocks so that the material cannot be discharged, or the large pieces falling off and causing inaccurate dosage. The output end of the vibration device is connected to the outlet pipe 10, and the outlet pipe 10 is vibrated to drive the screen 11 to vibrate, so that the powdered material is looser and the dosage is more accurate, avoiding blockage and affecting the subsequent process. When the vibration force of the vibration device is large enough, it can drive the entire feeding device to vibrate, so that the powdered material remaining in the gap is transferred by vibration, avoiding accumulation and residue, and making the inside of the feeding device cleaner and smoother. The aperture of the upper screen 11 is larger than the aperture of the lower screen 11, so as to facilitate the dispersion of the material layer by layer. When the filtering performance of the screen 11 decreases after long-term work, the outlet pipe 10 can also be removed for cleaning.

[0022] One end of the delivery pipeline 2 close to the outlet sealing plate 4 extends to the outside of the base 1, the outlet pipe 10 is close to the side of the base 1, and the vibration device is installed in the base 1, making the overall structure more compact and occupying less space.

[0023] The transition pipe 9 includes a side portion 91 connected to the conveying pipeline 2 and flush with the outlet sealing plate 4. The side portion 91 is tilted inward to transition to the outlet pipe 10 to prevent the material from being blocked in the conveying channel 2. After being pushed to the end of the conveying pipeline 2 by the conveying blades 6, it all falls along the transition pipe 9 to prevent the material from accumulating and deteriorating.

[0024] A cover body 12 rotatably connected to the hopper 8 is installed on one side of the hopper 8. The cover body 12 includes a closed state that rotates horizontally to cover the opening of the hopper 8 and an open state that rotates away from the hopper 8 to prevent impurities from falling into the hopper 8 when not in use.

[0025] When in use, open the cover 12 to guide the material into the hopper 8. When the feed motor 7 drives the rotating shaft 5 to rotate, the conveying blades 6 push the material from the end close to the inlet sealing plate 3 to the end close to the outlet sealing plate 4 along the conveying pipe 2. The material falls into the outlet pipe 10 from the transition pipe 9. Under the layer-by-layer screening of the screen 11 and the vibration of the vibration device, the material becomes looser, avoiding condensation into agglomerates and causing blockage, thereby improving the conveying process and improving the quality of pharmaceutical manufacturing.

[0026] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
