Description

Technical Field

[0001] This application relates to the technical field of tablet presses, and in particular, to a tablet press for tablet production. Background Art

[0002] A tablet press is a device used in the pharmaceutical industry to compress granular materials into tablets. Its core function is to compress granular materials of medicinal raw materials and excipients into tablets through high pressure.

[0003] However, a potential problem during the tablet pressing process is that a certain amount of particulate dust is generated under the friction and compression of the materials. These dusts may originate from raw materials, excipients, or the tablet pressing process itself, and their generation poses a direct threat to the quality of the tablets.

[0004] Particulate dust adheres to the surface of the formed tablets, increasing the weight of the tablets and causing a deviation between the actual dose and the expected dose, which may affect the efficacy of the drug and even, in extreme cases, result in serious consequences such as overdose or underdose for patients. Summary of the Invention

[0005] In order to reduce the possibility of dust adhering to the tablet surface, this application provides a tablet press for tablet production.

[0006] A tablet press for tablet production provided by this application adopts the following technical solutions: A tablet press for tablet production includes: A box body installed at the discharge port of the tablet press. The box body is provided with a feed trough, an annular cavity, and a discharge trough. The feed trough is used to receive the tablets formed by the tablet press, and the feed trough is connected to the discharge trough through the annular cavity; A rotating member rotatably connected to the box body. There is a gap between the axis of the rotating shaft and the axis of the annular cavity. The rotating member is connected with a plurality of telescopic components, and the telescopic components are distributed circumferentially along the rotating member. The end of the telescopic component away from the rotating member is slidably connected to the annular inner wall of the annular cavity; A dust screening ring is arranged in the annular cavity. A dust screening area is formed between the dust screening ring, the cavity wall of the annular cavity, and the adjacent telescopic components.

[0007] By adopting the above technical solution, the tablets enter the dust screening area from the output end of the tablet press through the feeding chute. When the rotating member rotates, it drives a plurality of telescopic components to rotate around the annular cavity. During the rotation process of the telescopic components, the end away from the rotating member is slidably connected to the annular inner wall of the annular cavity, forming a dynamic isolation barrier. The dynamic change of the telescopic components helps the tablets to be evenly distributed in the annular cavity. At the same time, this dynamic isolation also helps the stability of the tablets during the dust removal process. When the tablets pass through the dust screening area, the dust screening ring can effectively capture and filter the dust and impurities on the surface of the tablets, so that the dust and impurities on the surface of the tablets are removed through the dust screening ring, while the clean tablets continue to move forward and are discharged from the discharge chute, reducing the possibility of dust adhering to the surface of the tablets and improving the quality and production efficiency of the tablets.

[0008] Optionally, the rotating shaft of the rotating member is located at one end of the central axis of the annular cavity away from the feeding chute, and the dust screening ring is slidably connected to the rotating member.

[0009] By adopting the above technical solution, during the process of the tablets feeding from the annular cavity to the discharge, the rotating member rotates and the telescopic components contract, reducing the occupied space of the tablets, thereby promoting the tablets to be distributed and arranged along the direction perpendicular to the telescopic direction of the telescopic components. At the same time, under the sliding rotation of the dust screening ring, the possibility of the dust screening effect being reduced due to the overlapping of the tablets is reduced, thereby improving the dust removal effect of the tablets.

[0010] Optionally, the rotating shaft of the rotating member is located at the bottom of the central axis of the annular cavity.

[0011] By adopting the above technical solution, when the rotating member rotates, the movement path of the tablets in the annular cavity is longer, increasing the contact time between the tablets and the dust screening ring, thereby extending the dust screening stroke, enabling the tablets to have more opportunities to contact the dust screening ring and improving the dust removal effect.

[0012] Optionally, the outer wall of the dust screening ring is provided with a front dust screening groove and a rear dust screening groove penetrating therethrough. The front dust screening groove and the rear dust screening groove are symmetrically arranged along the radial direction of the dust screening ring and are located at the intersection position of the dust screening ring and the telescopic components.

[0013] By adopting the above technical solution, under the rotation of the rotating member, the tablets move on the dust screening ring, so that the tablets move from one telescopic component to the other telescopic component, and the dust falls from the front dust screening groove or the rear dust screening groove, thereby reducing the possibility of dust adhering to the surface of the tablets and improving the quality of the tablets.

[0014] Optionally, the dust screening ring is connected with a sliding rod, the sliding rod is slidably connected to the rotating member, one side of the box body is provided with an annular groove, the annular groove is provided with a corrugated surface, the sliding rod is inserted into the annular groove and is in contact with the corrugated surface, and the corrugated surface is used to make the sliding rod slide on the rotating member.

[0015] By adopting the above technical solution, when the rotating member rotates, it drives the sliding rod to rotate synchronously. The sliding rod rolls on the corrugated surface, so that while the sliding rod rotates, it slides, thereby screening the medicine. And, while screening the medicine, under the action of the telescopic assembly, it is arranged along the direction parallel to the rotation axis of the rotating member, thereby reducing the possibility of tablet stacking and improving the quality of the tablets.

[0016] Optionally, the sliding rod is connected with a positioning block. A positioning groove is formed through the outer wall of the dust screening ring. The positioning block is inserted into the positioning groove. The peripheral wall of the positioning block is attached to the peripheral wall of the positioning groove. The dust screening ring abuts against the sliding rod. A sliding groove is formed on one side of the rotating member. One end of the positioning block away from the sliding rod is inserted into the sliding groove. The sliding rod is slidably connected to the rotating member through the positioning block. The direction in which the positioning block is inserted into the positioning groove is perpendicular to the direction in which the positioning block is inserted into the sliding groove.

[0017] By adopting the above technical solution, under the action of the positioning block, the dust screening ring is positioned on the sliding rod. At the same time, under the action of the positioning block, the sliding rod is slidably connected to the rotating member, which is convenient for the installation and disassembly of the dust screening ring.

[0018] Optionally, a partition member is connected to the wall of the annular cavity. The partition member is obliquely arranged in the dust screening ring. A dust collection cavity is formed on the wall of the annular cavity. A dust collection box is installed in the dust collection cavity. The dust collection box is located at the bottom of the partition member.

[0019] By adopting the above technical solution, the inclined partition member is provided to guide the screened dust, so that the dust falls into the dust collection box, which is convenient for the centralized treatment of the dust and reduces the possibility of the dust falling onto the dust screening ring at the bottom, thereby reducing the possibility of blockage of the dust screening ring.

[0020] Optionally, a plurality of bristles are installed on the bottom wall of the partition member. One end of the bristles away from the partition member is in contact with the inner wall of the dust screening ring.

[0021] By adopting the above technical solution, when the dust screening ring rotates, the bristles brush over the dust screening ring, reducing the possibility of blockage of the dust screening ring, thereby improving the dust screening effect of the dust screening ring.

[0022] Optionally, the telescopic assembly includes a telescopic platform and a rolling wheel. One end of the telescopic platform is connected to the rotating member. There is a gap between the end of the telescopic platform away from the rotating member and the wall of the annular cavity. The rolling wheel is rotatably connected to the end of the telescopic platform away from the rotating member.

[0023] By adopting the above technical solution, a rolling wheel is provided to improve the smooth rotation of the telescopic component along with the rotating member. At the same time, a rotating wheel is provided to create a gap between the telescopic table and the cavity wall of the annular cavity. When the tablets are discharged, the dust falls through the gap between the telescopic table and the cavity wall of the annular cavity, further improving the dust removal effect of the tablets.

[0024] Optionally, the telescopic table includes a plurality of telescopic plates and a sliding plate. The plurality of telescopic plates are arranged in a straight line passing through the center of the rotating member. The telescopic plate at one end is connected to the rotating member, and there is a gap between adjacent telescopic plates. Adjacent telescopic plates are slidably connected by the sliding plate.

[0025] By adopting the above technical solution, when the tablets rotate, they can fall through the gap between adjacent telescopic plates. At the same time, the sliding plate is provided to slidably connect adjacent telescopic plates, reducing the possibility of squeezing and crushing the tablets when the telescopic component shortens, and improving the quality of the tablets.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The tablets enter the dust screening area from the output end of the tablet press through the feeding groove. When the rotating member rotates, it drives multiple sets of telescopic components to rotate around the annular cavity. During the rotation process of the telescopic components, the end far from the rotating member is slidably connected to the annular inner wall of the annular cavity, forming a dynamic isolation barrier. The dynamic change of the telescopic components helps the uniform distribution of the tablets in the annular cavity. At the same time, this dynamic isolation also helps the stability of the tablets during the dust removal process. When the tablets pass through the dust screening area, the dust screening ring can effectively capture and filter the dust and impurities on the surface of the tablets, so that the dust and impurities on the surface of the tablets are removed through the dust screening ring, while the clean tablets continue to move forward and are discharged from the discharging groove, reducing the possibility of dust adhering to the surface of the tablets and improving the quality and production efficiency of the tablets; 2. When the rotating member rotates, the movement path of the tablets in the annular cavity is longer, increasing the contact time between the tablets and the dust screening ring, thereby extending the dust screening stroke, enabling the tablets to have more opportunities to contact the dust screening ring, and improving the dust removal effect; 3. When the tablets rotate, they can fall through the gap between adjacent telescopic plates. At the same time, the sliding plate is provided to slidably connect adjacent telescopic plates, reducing the possibility of squeezing and crushing the tablets when the telescopic component shortens, and improving the quality of the tablets.

[0032] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 drawings.

[0033] The embodiment of the present application discloses a tablet press for tablet production.

[0034] Refer to Figure 1 and Figure 2, A tablet press for tablet production, comprising a box body 1, a rotating member 2 and a dust screening ring 3. The box body 1 is fixedly installed at the discharge port of the tablet press. The box body 1 is provided with a feed trough 111, an annular cavity 112 and a discharge trough 113. The input end of the feed trough 111 is located at the discharge port of the tablet press. The feed trough 111 is used to receive the tablets formed by the tablet press. The feed trough 111 and the discharge trough 113 are connected through the annular cavity 112. The bottom wall of the feed trough 111 is inclined. And the rotating member 2 is located at one end of the output end of the inclined bottom of the feed trough 111. The bottom of the inclined direction of the feed trough 111 is located above the rotation axis of the rotating member 2. So that the tablets slide along the inclined trough of the feed trough 111 into the annular cavity 112. The bottom wall of the discharge trough 113 is inclined. And the rotating member 2 is located at one end of the input end of the inclined top of the discharge trough 113. The top of the inclined direction of the discharge trough 113 is located below the rotation axis of the rotating member 2. So that the tablets slide out of the annular cavity 112 along the inclined trough of the discharge trough 113. The rotation axis of the rotating member 2 is rotatably connected to the inner wall of the box body 1. A driving member 21 is fixedly installed on the outer wall of the box body 1. The output end of the driving member 21 is fixedly connected to the rotation axis of the rotating member 2. So that the rotating member 2 rotates under the driving action of the driving member 21. There is a gap between the axis line of the rotation axis and the axis line of the annular cavity 112. A plurality of telescopic assemblies 4 are fixedly connected to the outer wall of the rotating member 2. The telescopic assemblies 4 are distributed circumferentially along the rotating member 2. The end of the telescopic assembly 4 away from the rotating member 2 is slidably connected to the annular inner wall of the annular cavity 112. The dust screening ring 3 is arranged in the annular cavity 112. A plurality of dust screening holes 31 are formed through the outer wall of the dust screening ring 3. A dust screening area is formed between the dust screening ring 3, the cavity wall of the annular cavity 112 and the adjacent telescopic assemblies 4. So that under the action of the telescopic assemblies 4, the annular cavity 112 is divided into a plurality of dust screening areas.

[0035] The inclined direction of the feed trough 111 is collinear with the inclined direction of the discharge trough 113 and is located at the bottom of the rotation center of the rotating member 2.

[0036] The rotation axis of the rotating member 2 is located at one end of the central axis of the annular cavity 112 away from the feed trough 111. The dust screening ring 3 is slidably connected to the rotating member 2.

[0037] When the tablets are fed from the annular cavity 112 to the discharge, the rotating member 2 rotates and the telescopic assemblies 4 contract, reducing the occupied space of the tablets, thus promoting the tablets to be distributed and arranged perpendicular to the telescopic direction of the telescopic assemblies 4. At the same time, under the sliding rotation of the dust screening ring 3, the possibility of the reduction of the dust screening effect caused by the stacking of the tablets is reduced, thereby improving the dust removal effect of the tablets.

[0038] The rotation axis of the rotating member 2 is located at the bottom of the central axis of the annular cavity 112, so that when the rotating member 2 rotates, the movement path of the tablets in the annular cavity 112 is longer, increasing the contact time between the tablets and the dust screening ring 3, thereby extending the dust screening stroke, enabling the tablets to have more opportunities to contact the dust screening ring 3 and improving the dust removal effect.

[0039] The outer wall of the dust screening ring 3 is provided with a front dust screening groove 32 and a rear dust screening groove 33 in a penetrating manner. The front dust screening groove 32 and the rear dust screening groove 33 are symmetrically arranged along the radial direction of the dust screening ring 3. The front dust screening groove 32 and the rear dust screening groove 33 are in a shape of an eight with a small opening at one end close to the center of the rotation axis. And they are located at the intersection position of the dust screening ring 3 and the telescopic assembly 4. Under the rotation of the rotating part 2, the tablets move on the dust screening ring 3, so that the tablets move from one telescopic assembly 4 to the other telescopic assembly 4 at the other end, and the dust drops from the front dust screening groove 32 or the rear dust screening groove 33, thereby reducing the possibility of dust adhering to the tablet surface and improving the quality of the tablets.

[0040] Furthermore, for facilitating the maintenance or replacement of the internal structure of the box body 1, the box body 1 includes an installation shell 11 and a cover body 12. A channel is opened on one side of the installation shell 11. When the cover body 12 is covered on the installation shell 11, a channel for communicating the feeding groove 111, the annular cavity 112 and the discharging groove 113 is formed. The driving part 21 is fixedly installed on the side of the installation shell 11 away from the cover body 12, and the rotating part 2 is rotatably connected with the installation shell 11. In this embodiment, the cover body 12 is fixed to the installation shell 11 by bolts.

[0041] Refer to Figure 2 and Figure 3 The dust screening ring 3 is detachably connected with a sliding rod 5. The sliding rod 5 is slidably connected with the rotating part 2. An annular groove 121 is opened on the side of the cover body 12 close to the installation shell 11. A corrugated surface is provided in the annular groove 121. The protruding and recessed directions of the corrugated surface are parallel to the extending direction of the rotation axis of the rotating part 2. The sliding rod 5 is inserted into the annular groove 121 and is in fit with the corrugated surface. The corrugated surface is used to make the sliding rod 5 slide on the rotating part 2. One end of the sliding rod 5 away from the corrugated surface is fixedly connected with a spring 52, and one end of the spring 52 away from the sliding rod 5 is fixedly connected with the rotating part 2.

[0042] When the rotating part 2 rotates, it drives the sliding rod 5 to rotate synchronously. The sliding rod 5 rolls on the corrugated surface, so that while the sliding rod 5 rotates, it slides, thereby screening the medicine. And, while screening the medicine, under the action of the telescopic assembly 4, it is arranged along the direction parallel to the rotation axis of the rotating part 2, thereby reducing the possibility of tablet stacking and improving the quality of the tablets.

[0043] The sliding rod 5 is connected with positioning blocks 51. In this embodiment, the number of positioning blocks 51 is two, and they are located at both ends of the sliding rod 5. The outer wall of the dust screening ring 3 is penetrated with positioning grooves 34. The positioning blocks 51 are inserted into the positioning grooves 34. The peripheral wall of the positioning block 51 is in contact with the peripheral wall of the positioning groove 34. The dust screening ring 3 abuts against the sliding rod 5. A sliding groove 22 is formed on one side of the rotating member 2. One end of the positioning block 51 away from the sliding rod 5 is inserted into the sliding groove 22. The sliding rod 5 is slidably connected to the rotating member 2 through the positioning block 51. The direction in which the positioning block 51 is inserted into the positioning groove 34 is perpendicular to the direction in which the positioning block 51 is inserted into the sliding groove 22.

[0044] A partition member 6 is fixedly connected to the wall of the annular cavity 112. The partition member 6 is obliquely arranged in the dust screening ring 3. A dust collecting cavity is formed on the wall of the annular cavity 112. The dust collecting cavity is located at the bottom of the annular cavity 112. An opening is provided on one side of the wall of the dust collecting cavity. A dust collecting box 7 is installed in the dust collecting cavity. The dust collecting box 7 is located at the bottom in the inclined direction of the partition member 6, guiding the screened dust so that the dust drops into the dust collecting box 7, facilitating the centralized treatment of the dust, reducing the possibility of the dust dropping onto the dust screening ring 3 at the bottom, and further reducing the possibility of blockage of the dust screening ring 3. The dust collecting box 7 is installed in the dust collecting cavity through the opening of the dust collecting cavity. The bottom wall of the dust collecting box 7 is in contact with the bottom wall of the dust collecting cavity, facilitating the disassembly and assembly of the dust collecting box 7.

[0045] A plurality of bristles 61 are installed on the bottom wall of the partition member 6. One end of the bristles 61 away from the partition member 6 is in contact with the inner wall of the dust screening ring 3. When the dust screening ring 3 rotates, the bristles 61 brush over the dust screening ring 3, reducing the possibility of blockage of the dust screening ring 3 and further improving the dust screening effect of the dust screening ring 3.

[0046] The telescopic assembly 4 includes a telescopic platform and a rolling wheel 41. One end of the telescopic platform is fixedly connected to the rotating member 2. There is a gap between the other end of the telescopic platform away from the rotating member 2 and the wall of the annular cavity 112. The rolling wheel 41 is rotatably connected to the other end of the telescopic platform away from the rotating member 2. When the tablets are discharged, the dust drops through the gap between the telescopic platform and the wall of the annular cavity 112, further improving the dust removal effect of the tablets.

[0047] The telescopic platform includes a plurality of telescopic plates 42 and a sliding plate. The plurality of telescopic plates 42 are arranged in a straight line passing through the center of the rotating member 2. The telescopic plate 42 at one end is fixedly connected to the rotating member 2. There is a gap between adjacent telescopic plates 42. The adjacent telescopic plates 42 are slidably connected by the sliding plate. When the tablets rotate, they can drop through the gap between adjacent telescopic plates 42. At the same time, the sliding plate is provided to slidably connect the adjacent telescopic plates 42.

[0048] Refer to Figure 4, a baffle 8 is slidably connected to the installation shell 11. The baffle 8 is used to block the opening height of the discharge port. An adjustment groove 81 is formed at one end of the baffle 8 away from the discharge port. An adjustment member 82 is inserted into the adjustment groove 81. The adjustment member 82 slides within the adjustment groove 81. One end of the adjustment member 82 away from the adjustment groove 81 is threadedly connected to the installation shell 11. When adjusting the height of the discharge port, slide the baffle 8 to adjust the height of the discharge port, and then turn the adjustment member 82 to fix the baffle 8 on the installation shell 11.

[0049] The implementation principle of a tablet press in an embodiment of the present application is as follows: The tablets slide from the discharge port of the tablet press to the feed trough 111, and then slide from the feed trough 111 to the dust screening area. The driving member 21 drives the rotating member 2 to rotate, and the tablets move towards the rotating member 2. The rotation of the rotating member 2 drives the telescopic assembly 4 to be compressed, and the telescopic assembly 4 becomes shorter. At the same time, the dust screening ring 3 slides to screen the medicine. When the medicine rotates to the bottom of the rotating shaft of the rotating member 2, under the action of the dust screening ring 3 and the telescopic assembly 4, the tablets are attached to the wall of the annular cavity 112. Adjust the height of the discharge port so that the height of the discharge port is between the height of one tablet and the height of two tablets, so that the tablets are arranged in a direction parallel to the rotating member 2 when discharging, reducing the possibility of the tablets being stacked together and improving the quality and production efficiency of the tablets.

[0050] The above are all the preferred embodiments of the present application. This embodiment is only an explanation of the present application and does not limit the protection scope of the present application in turn. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
