Description

Technical Field

[0001] The utility model relates to the technical field of tablet presses, and particularly to a full-automatic high-speed rotary tablet press. Background Art

[0002] Tablet presses for pharmaceutical use are mainly used to press pharmaceutical powders or granular substances into tablets through molds. Such tablet presses can make the medicines into tablets with uniform specifications and neat appearances, thereby improving the quality of the medicines and facilitating the storage and use of the medicines.

[0003] For example, the Chinese utility model patent disclosed with the publication number CN215243138U: Rotary Tablet Press. This application improves the feeding device by dividing the existing feeding device into a material cylinder and a blanking cylinder, and arranging a distributor between the feeding cylinder and the blanking cylinder, so that the feeding cylinder is detachably connected to the distributor. It can not only ensure the uniformity of powders with poor fluidity and improve the quality of the products pressed by the pressing die device. However, when the powder is discharged through the rotating separation disk in this application, the powder will enter the rotating disk through the blanking cylinder. On the one hand, this kind of blanking method is a non-contact blanking method, and the single blanking amount cannot be accurately controlled, so that some powders will spill out, resulting in waste. On the other hand, the overall efficiency of the blanking method in this application is relatively low, and simply using the high-speed rotation of the separation disk to achieve the uniform distribution of particles or powders cannot solve the problem of blockage during material separation and blanking.

DETAILED DESCRIPTION OF THE EMBODIMENTS

A feeding hopper 4 is fixedly installed on the chassis 1 above the rotary tablet pressing mechanism 3. Two material distributing mechanisms 5 are arranged between the rotary tablet pressing mechanism 3 and the feeding hopper 4. The material distributing mechanism 5 includes a material distributing box 6. A plurality of spreading impellers 7 are movably installed on the inner top of the material distributing box 6. A guide pipe 8 is fixedly installed on one side of the top of the material distributing box 6. A displacement rod 10 is movably installed inside the guide pipe 8. A connecting hopper 9 is fixedly installed on the top of the guide pipe 8. The top of the connecting hopper 9 is fixedly installed on one of the discharge pipes at the bottom of the feeding hopper 4.

[0023] As Figures 1-2 shown, a toothed ring 27 is fixedly installed on the outside of the rotary tablet pressing mechanism 3;

[0024] As Figure 1 、 Figures 3-4 shown, a gear box 11 is also fixedly installed on the material distributing box 6 on one side of the guide pipe 8. A first transmission gear 14 is rotatably installed inside the gear box 11. A plurality of driven gears 15 are rotatably installed inside the gear box 11 on one side of the first transmission gear 14. The first transmission gear 14 is meshed and connected with one of the driven gears 15, and the plurality of driven gears 15 are meshed and connected with each other. A top cover 12 is fixedly installed on the top of the gear box 11. A fixed seat 16 is fixedly installed on one side of the top of the top cover 12. A bushing 17 is fixedly installed on the top of the fixed seat 16. A rotating shaft 18 is rotatably installed inside the bushing 17. The bottom of the rotating shaft 18 is inserted and installed inside the first transmission gear 14. A second transmission gear 19 is fixedly installed on the rotating shaft 18 above the bushing 17. The second transmission gear 19 is meshed and connected with the toothed ring 27. When the rotary tablet pressing mechanism 3 is driven by the driving motor 2 to rotate and press tablets, the toothed ring 27 can cooperate with the second transmission gear 19, the rotating shaft 18, and the first transmission gear 14 to drive the plurality of driven gears 15 to rotate synchronously. The center position of the spreading impeller 7 is fixedly installed on the connecting shaft at the bottom of the corresponding driven gear 15. A bottom cover 13 is fixedly installed on the bottom of the material distributing box 6. A blanking through groove 20 is opened on one side of the inner bottom of the bottom cover 13. The bottom cover 13 is also fixedly installed on one side of the top of the chassis 1, and the blanking through groove 20 is placed above the tablet pressing powder groove of the rotary tablet pressing mechanism 3. With the transmission of the toothed ring 27, the second transmission gear 19, the rotating shaft 18, the first transmission gear 14, and the driven gears 15, it is convenient to spread the material distributed from the feeding hopper 4 and the connecting hopper 9, so that the material can continuously be conveyed into the tablet pressing powder groove of the rotary tablet pressing mechanism 3 through the blanking through groove 20;

[0025] As Figures 3-5As shown, a first fixing ring 21 is fixedly installed at the lower inner position of the material guiding pipe 8. At the central position inside the first fixing ring 21, an installation sleeve 22 is provided. A plurality of connecting rods 23 are fixedly connected between the installation sleeve 22 and the first fixing ring 21. The displacement rod 10 is inserted and installed inside the installation sleeve 22. A second fixing ring 24 is fixedly installed on the displacement rod 10 located inside the installation sleeve 22. A compression spring 26 is sleeved on the displacement rod 10 between the second fixing ring 24 and the inner top diameter of the installation sleeve 22. An impact piece 25 is fixedly installed at the top of the displacement rod 10. The bottom of the displacement rod 10 is in an arc-shaped block structure and extends into the corresponding paving impeller 7. The displacement rod 10 is inserted and installed inside the installation sleeve 22 through the second fixing ring 24 and the compression spring 26, and in cooperation with the paving impeller 7, the displacement rod 10 can drive the impact piece 25 to move up and down reciprocally inside the material guiding pipe 8, thereby preventing the powder from clogging.

[0026] It should be noted that the present utility model is a fully automatic high-speed rotary tablet press. When performing tablet pressing on the medicinal powder, the medicinal powder can be continuously conveyed into the connecting hopper 9 through the feeding hopper 4. Then, the medicinal powder in the connecting hopper 9 enters the cavity between the material distributing box 6 and the bottom cover 13 through the material guiding pipe 8. At the same time, the rotary tablet pressing mechanism 3 runs rotationally through the driving motor 2 and the transmission mechanism. That is, the toothed ring 27 outside the rotary tablet pressing mechanism 3 is meshed and connected with the second transmission gear 19 to drive the second transmission gear 19 to rotate. Then, the second transmission gear 19 drives the rotating shaft 18 to rotate inside the shaft sleeve 17, and the bottom of the rotating shaft 18 drives the first transmission gear 14 to rotate. Since the first transmission gear 14 is meshed and connected with one of the driven gears 15, multiple driven gears 15 are meshed and connected to rotate with each other. Thus, three of the driven gears 15 drive the corresponding paving impellers 7 to rotate through the connecting shafts, and the three paving impellers 7 can continuously convey the medicinal powder between the material distributing box 6 and the bottom cover 13 towards the blanking through groove 20. That is, when the powder pressing groove inside the rotary tablet pressing mechanism 3 moves to the position below the blanking through groove 20, the powder enters through the blanking through groove 20, thereby completing the injection of the medicinal powder. At the same time, when one of the paving impellers 7 rotates, it will simply use the arc-shaped block structure at the bottom of the displacement rod 10 to push up the displacement rod 10. Then, the displacement rod 10 moves upward inside the installation sleeve 22, and the second fixing ring 24 compresses the compression spring 26 towards the inner top of the installation sleeve 22. At the same time, the impact piece 25 at the top of the displacement rod 10 impacts and disperses the medicinal powder inside the material guiding pipe 8. When the blade of the paving impeller 7 disengages from the displacement rod 10, the displacement rod 10 moves downward and resets by virtue of the elastic force of the compression spring 26 rebounding. The above actions are repeated later.

Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments.
