Description

Technical Field

[0001] The utility model relates to the field of tablet medicine production, in particular to a feeding device. Background Art

[0002] Tablets refer to preparations in the form of sheets or special-shaped sheets compressed from fine powder of medicinal materials or extracts of medicinal materials plus fine powder of medicinal materials or excipients. They can be compressed by a pharmaceutical tablet press and are formed into tablets by pressure and shaping. After the preparation of tablets, they need to be filled and transported.

[0003] In the process of conveying tablets, tablet powder will inevitably remain on the surface of the conveying channel. If these tablet powders are not cleaned in time, when another type of tablet is conveyed, the residual tablet powder will adhere to the surface of other tablets, causing cross contamination to the tablets to be conveyed, thereby affecting the therapeutic effect of the tablet.

[0020] Reference Manual Attached Figure 1-3 A feeding device comprises a feeding frame 2 and a bracket 1 supporting the feeding frame 2, a cleaning frame 3 is movably arranged on the upper end of the feeding frame 2, a rotating shaft 4 is arranged on the inner wall of the cleaning frame 3 for horizontal rotation, and a cleaning brush 5 is evenly arranged on the surface of the rotating shaft 4 located in the inner cavity of the cleaning frame 3, one end of the rotating shaft 4 movably penetrates and extends to the outside of the cleaning frame 3, and a toothed disc 6 is fixedly connected to the outer end of the rotating shaft 4, and a rack 7 movably meshed with the toothed disc 6 is fixedly arranged on the outer wall of the feeding frame 2, a motor 8 driving the other end of the rotating shaft 4 is also fixedly connected to the outer side of the cleaning frame 3, and a cleaning brush 5 is evenly arranged on the inner wall of the cleaning frame 3 for docking with the feeding frame 3. The scraper 9 on the inner wall of the frame 2 and the top of the inner cavity of the cleaning frame 3 are fixedly connected with an exhaust plate 10, and the upper end of the cleaning frame 3 is fixedly provided with an exhaust box 11 connected to the exhaust plate 10, and the outer side of the exhaust box 11 is fixedly provided with an exhaust fan 1101 connected to the inner cavity, and the outer wall of the exhaust box 11 is also connected to the exhaust plate 10 through an exhaust pipe 1102, and the bottom of the exhaust plate 10 is evenly provided with exhaust holes connected to the inner cavity, the outer wall of the feeding frame 2 is fixedly provided with a limit rail 202, and the two ends of the limit rail 202 are fixedly connected to the limit block 203, and the inner wall of the cleaning frame 3 is provided with a limit groove 204 that slides with the limit rail 202.

[0021] Based on the above structure, when the device is in use, the staff starts the motor 8 and the exhaust fan 1101 through the external switch, and the motor 8 drives the rotating shaft 4 at the power end to rotate, and the gear plate 6 at the outer end of the rotating shaft 4 engages with the rack 7 on the outside of the feeding frame 2, and cooperates with the limiting groove 204 on the inner wall of the cleaning frame 3 and the limiting rail 202 on the outer wall of the feeding frame 2. At this time, under the drive of the motor 8, the cleaning frame 3 moves along the direction of the rack 7 on the outside of the feeding frame 2. During the movement of the cleaning frame 3, on the one hand, when the rotating shaft 4 rotates, the cleaning brush 5 on the outer wall will rotate and clean the inner wall of the feeding frame 2, and on the other hand, the scraper 9 on the inner wall of the cleaning frame 3 will scrape the medicine attached to the inner wall of the feeding frame 2, thereby more thoroughly cleaning the medicine dust attached to the inner wall of the feeding frame 2, and then, under the start-up of the external exhaust fan 1101 and in conjunction with the exhaust pipe 1102, the medicine dust enters the inner cavity of the exhaust plate 10 from the exhaust hole, and is finally extracted by the exhaust pipe 1102 to the exhaust box 11 for storage, thereby avoiding cross-contamination between residual powder and the transported tablets, and effectively ensuring the therapeutic effect of the transported tablets.

[0022] Among them, a vibration motor 201 is fixedly connected to the bottom of the feeding frame 2, which can vibrate and lift up the dust attached to the upper end of the feeding frame 2, thereby achieving an auxiliary cleaning effect.

[0023] The contact surfaces of the limiting rail 202 and the limiting groove 204 are both designed with a smooth surface structure, which can reduce sliding friction and facilitate the smooth movement of the cleaning frame 3.
