Description

Technical Field

[0001] The utility model relates to the field of tablet presses, in particular to a medicine powder conveying mechanism of an azithromycin dispersible tablet press. Background Art

[0002] The existing drug powder conveying mechanism of azithromycin dispersible tablets is complex in structure, inconvenient to maintain, and easily causes powder to scatter. Summary of the invention

[0003] The utility model hopes to provide a medicine powder conveying mechanism for an azithromycin dispersible tablet press, and the specific scheme is as follows:

[0004] A medicine powder conveying mechanism of an azithromycin dispersible tablet press comprises a powder trough and a powder output mechanism, wherein a discharge pipe is arranged at one end of the powder trough, a screw is arranged in the discharge pipe, the discharge pipe and the screw are arranged in cooperation, a motor is arranged at one end of the screw, the motor drives the screw to rotate, a powder opening is arranged at the part of the discharge pipe located in the powder trough, and the discharge pipe is arranged in cooperation with the powder output mechanism.

[0005] The powder delivery mechanism comprises a delivery pipeline, on which a valve is arranged, and the valve is opened once at a certain time, so that a certain amount of powder flows into the tablet slot below.

[0006] An arc-shaped guide plate is provided at one end of the discharge pipe, and the end of the arc-shaped guide plate is located in a straight line with the center of the conveying pipeline. The above design is to ensure that the powder can fall into the center of the conveying pipeline as much as possible.

[0007] The heights of the two sides of the arc-shaped drainage plate are higher than the height of the middle part of the arc-shaped drainage plate. This design is to prevent the powder from sliding out from the two sides and falling on the ground.

[0008] The conveying pipeline includes an open portion, and the designer of the open portion is to prevent the powder from falling on the ground as much as possible.

[0009] The utility model conveys the medicine powder to the powder output mechanism through the screw rod, and the design can ensure the stability of the powder delivery amount as much as possible, and the structure is simple and convenient for maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is a schematic diagram of the structure of the powder conveying mechanism of the azithromycin dispersible tablet press of the utility model. Figure 1 ;

[0011] Figure 2 This is a schematic diagram of the structure of the powder conveying mechanism of the azithromycin dispersible tablet press of the utility model. Figure 2 ;

[0012] The numbers are as follows: 21. powder tank; 22. powder output mechanism; 23. discharge pipe; 24. screw; 25. motor; 26. powder opening; 27. conveying pipeline; 28. valve; 29. ​​arc guide plate; 210. open part. DETAILED DESCRIPTION

[0013] Combine the following Figure 1-2 For further explanation:

[0014] A medicine powder conveying mechanism of an azithromycin dispersible tablet press comprises a powder tank 21 and a powder output mechanism 22, a discharge pipe 23 is provided at one end of the powder tank 21, a screw 24 is provided in the discharge pipe 23, the discharge pipe 23 and the screw 24 are arranged in cooperation, a motor 25 is provided at one end of the screw 24, the motor 25 drives the screw 24 to rotate, a powder opening 26 is provided at the part of the discharge pipe 23 located in the powder tank 21, and the discharge pipe 23 is arranged in cooperation with the powder output mechanism 22. That is, the medicine powder is conveyed to the powder output mechanism 22 by the screw 24, and this design can ensure the stability of the powder conveying amount as much as possible.

[0015] The powder delivery mechanism 22 includes a delivery pipe 27, on which a valve 28 is provided, and the bottom of the delivery pipe 27 is matched with a tablet trough (i.e., a shelf for placing the powder, and after completing the steps of the utility model, the powder will be tableted). The valve 28 will open once at a certain time, so that a certain amount of powder will flow into the tablet trough below.
