DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figure 1-5 A drug preparation dust removal device comprises a shell 6, a mounting bucket 13 is fixedly installed on the outer side of the bottom end of the shell 6 through a plurality of supporting members, a rotating platform 5 is arranged above the mounting bucket 13, and a mounting column 8 is rotatably installed at the top center of the rotating platform 5, a scraping plate 10 is fixed to one end of the outer wall of the mounting column 8, and a baffle 4 is fixed to the other end of the outer wall of the mounting column 8, one end of the baffle 4 and the scraping plate 10 are welded to the inner wall of the shell 6, two air jets 9 are embedded in the scraping plate 10, a servo motor 12 is installed at the bottom end of the mounting bucket 13, and the output end of the servo motor 12 is fixed to the bottom center of the rotating platform 5. The top of the rotating table 5 is provided with a plurality of tablet pressing grooves 11 at equal angles, and the inside of the rotating table 5 is provided with a plurality of empty grooves 23, and a plurality of moving bars 24 are slidably installed inside the empty grooves 23, and a plurality of return spring rods 26 are fixed to the top of the moving bars 24 and the top of the inside of the empty grooves 23, and a movable rod 25 is fixed to the inner wall of the movable bar 24, and the top of the movable rod 25 extends to the inside of the tablet pressing groove 11 and is installed with a push plate 22, and the bottom end of the movable rod 25 extends to the bottom of the rotating table 5 and is installed with a fixed ball 20, and a circular arc-shaped support bar 21 is fixed to the bottom end of the inside of the installation bucket 13, and both ends of the support bar 21 are designed with inclined surfaces;

[0023] The bottom end of the scraping plate 10 and the top end of the rotating table 5 are on the same plane, and the distance between the bottom end of the baffle 4 and the top end of the rotating table 5 is 0.3 cm;

[0024] An annular plate is fixed to the inner wall of the installation bucket 13, and a plurality of balls are embedded at equal intervals on the top of the annular plate;

[0025] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the servo motor 12 is started to drive the rotating table 5 to rotate regularly. When the movable rod 25 moves to the vicinity of the support bar 21, the fixed ball 20 contacts the inclined surface of the support bar 21 and is squeezed upward, thereby causing the movable bar 24 to overcome the movement of the return spring rod 26, causing the push plate 22 to move up to a position where the top is flush with the top of the tablet pressing groove 11, so that the tablets inside the corresponding hole can be pushed out. As the rotating table 5 continues to rotate, the scraping plate 10 sweeps the tablets and medicine ash on the surface of the rotating table 5 and makes them fall into the inside of the shell 6. At this time, the air nozzle 9 can also blow out a slight airflow to assist in sweeping the ash.

[0026] A base 7 is provided below the housing 6, and vertical plates 1 are fixed on both sides of the top of the base 7, and a fixing plate 3 is installed on one side of the vertical plate 1, and one side of the fixing plate 3 is welded to the outer wall of the housing 6;

[0027] Two electric push rods 17 are installed at the top of the base 7, and a fixed platform 18 is installed at the top of the two electric push rods 17. A receiving bucket 19 is arranged above the fixed platform 18, and a screening box 16 is arranged inside the receiving bucket 19. The tops of the receiving bucket 19 and the screening box 16 are on the same horizontal plane as the bottom of the shell 6. A plurality of supporting blocks are arranged below the screening box 16, and the supporting blocks are all welded to the inner wall of the receiving bucket 19.

[0028] A plurality of limiting holes 2 are vertically penetrated inside the fixing plate 3, and fixing blocks 15 are fixed on both sides of the receiving bucket 19, and limiting columns 14 matching the limiting holes 2 are fixed on the top of the fixing blocks 15, and the tops of the limiting columns 14 penetrate to the top of the limiting holes 2;

[0029] The top of the fixed platform 18 is provided with a plurality of slide grooves, and one end of each slide groove extends to one end of the fixed platform 18. The bottom of the receiving bucket 19 is provided with a plurality of matching slide blocks, and the receiving bucket 19 is slidably connected with the fixed platform 18 through the cooperation between the slide blocks and the slide grooves.

[0030] Specifically, Figure 1 and Figure 2 As shown, the tablets and powders that fall into the shell 6 enter the screening box 16 under the guidance of the inner wall of the shell 6. The powders with smaller particles pass through the screening box 16 and enter the receiving bucket 19, while the tablets with larger particles remain in the screening box 16. At this time, the electric push rod 17 can be started to drive the fixed platform 18 to move downward, so that the limiting column 14 is separated from the limiting hole 2, so that the sliding of the receiving bucket 19 above the fixed platform 18 is no longer restricted. The tablets and powders can be taken out by pulling the receiving bucket 19 out from above the fixed platform 18 and then pulling the screening box 16 upward out of the receiving bucket 19.

[0031] Working principle: This device is attached to a tablet press to work. In this device, only the dust cleaning part of the tablet press in the prior art is disclosed, and the basic working principle of the tablet press is not fully drawn. In the tablet press in the prior art, a mechanism for injecting powder and a mechanism for tablet pressing are also provided above the rotating table 5. The mounting column 8 of the device can be fixedly connected with related equipment to ensure stability;

[0032] When the device is working, the tablet press injects medicine powder into the leftmost tablet pressing groove 11 above the rotating table 5 and performs tablet pressing operation. For the convenience of understanding, this hole position is referred to as A hole here. During this process, the servo motor 12 drives the rotating table 5 to rotate regularly. When the internal A hole passes through the baffle 4, the movable rod 25 corresponding to the hole position moves to the vicinity of the support bar 21, and the fixed ball 20 contacts the inclined surface of the support bar 21 and is squeezed upward, thereby causing the movable bar 24 to overcome the movement of the reset spring rod 26, causing the push plate 22 to move up to a position where the top end is flush with the top end of the tablet pressing groove 11, so that the tablet inside the A hole is pushed out;

[0033] Most of the medicine dust generated during the tableting process is gathered at the top of the rotating table 5. Due to the existence of the support bar 21, the tableting groove 11 at the larger angle between the baffle plate 4 and the scraper plate 10 is blocked by the push plate 22, so there is no internal space at this time. Therefore, as the rotating table 5 continues to rotate, the scraper plate 10 sweeps the tablets and medicine dust on the surface of the rotating table 5 and makes them fall into the inside of the shell 6. At this time, the air nozzle 9 can also blow out a slight airflow to assist in sweeping the dust. The existence of the baffle plate 4 can prevent the tablets from moving back to the tableting working area.

[0034] After the hole A passes through the scraping plate 10, it has been cleaned, and the fixed ball 20 has also left the support bar 21. Therefore, under the rebound of the reset spring rod 26, the push plate 22 is also smoothly reset, which is convenient for a new round of tablet pressing operation.

[0035] The tablets and powders that fall into the shell 6 enter the screening box 16 under the guidance of the inner wall of the shell 6. The powders with smaller particles pass through the screening box 16 and enter the receiving bucket 19, while the tablets with larger particles remain in the screening box 16. Subsequently, the electric push rod 17 can be started to drive the fixed platform 18 to move downward, so that the limiting column 14 is separated from the limiting hole 2. Subsequently, the receiving bucket 19 is pulled out from above the fixed platform 18, and then the screening box 16 and the receiving bucket 19 are separated, so that the tablets and powders can be taken.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
