Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Persons skilled in the art shall connect the components in this case in sequence. For the specific connection and operation sequence, reference shall be made to the following working principle. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process.

[0021] During the use of a traditional tablet press, powdery medicine is added into the interior of a mold from a feed inlet. After the forming process of the tablets is completed, in order to prevent the medicines from affecting each other, when forming other medicines, it is necessary to clean the powder inside the mold. The traditional cleaning method is to remove the mold from the tablet press and manually clean the interior of the mold. This cleaning method is rather cumbersome, thus reducing the cleaning efficiency of the mold.

[0022] In view of this, the present utility model provides a tablet press mold with a self-cleaning function. The medicine powder is added into the interior of an outer mold from the feed inlet, and the formed tablets are discharged outwards from a discharge port. The interior of the mold is cleaned by a cleaning device, and there is no need to remove the mold from the tablet press. The automatic cleaning of the cleaning brush replaces the original manual cleaning. This cleaning method is rather simple, thus improving the cleaning efficiency of the mold.

[0023] Embodiment 1: As can be seen from Figure 1 、 2 、3 and 4, the tablet press mold with a self-cleaning function includes a first gear 1. The outer wall of the first gear 1 is rotatably connected with a top mold 3. A bottom of the top mold 3 is provided with an outer mold 4. An inner wall of the outer mold 4 is provided with a cylinder 6. An inner wall of the top mold 3 is provided with two feed inlets 8. An inner wall of the outer mold 4 is provided with two limiting rods 9. Outer walls of the two limiting rods 9 are both movably connected with the inner wall of the top mold 3. The top of the top mold 3 is detachably connected with a second servo motor 12. An output end of the second servo motor 12 is detachably connected with a second gear 11. An outer wall of the second gear 11 meshes with an outer wall of the first gear 1. The tablet press mold with a self-cleaning function further includes: a cleaning device 2, installed inside the first gear 1; a demolding device 5, installed inside the outer mold 4; wherein, the cleaning device 2 can prevent subsequent medicines from being contaminated during forming, and the demolding device 5 facilitates demolding of the medicines.

[0024] In the specific implementation process, it is particularly pointed out that the top mold 3 and the outer mold 4 are combined together through the limiting rods 9. The model of the cylinder 6 is SCA2-CB-100B-300-T0H3-D-Y, and the model of the second servo motor 12 is 110ZYT. When the second servo motor 12 works, it drives the first gear 1 to rotate a certain angle through the second gear 11. The powdery medicament is added into the interior of the outer mold 4 from the feed inlet 8. The cleaning device 2 prevents subsequent medicines from being contaminated during tablet pressing, and the demolding device 5 quickly demolds the medicines.

[0025] Furthermore, two extrusion holes 7 are machined at the top of the top mold 3;

[0026] In the specific implementation process, it is particularly worth noting that the extrusion hole 7 facilitates the external tablet pressing device of the tablet press to extrude and form the medicine;

[0027] Specifically, when using the tablet press mold with self-cleaning function, after the top mold 3 and the outer mold 4 are closed through the limit rod 9, when the second servo motor 12 works, it drives the first gear 1 to rotate a certain angle through the second gear 11. At this time, the feed port 8 rotates above the demolding device 5, and the powdery medicine is sent to the designated position. The first gear 1 continues to rotate, aligning the extrusion hole 7 with the demolding device 5. The extrusion device of the tablet press cooperates with the internal structure of the demolding device 5 to extrude the medicine into flakes, and the demolding device 5 quickly demolds the medicine, and the cleaning device 2 is used to clean the internal structure of the demolding device 5.

[0029] In the specific implementation process, it is particularly worth noting that the transmission device 204 is composed of two grooved pulleys and a belt. The model of the first servo motor 202 is 110ZYT. When the tablet press works, it pushes the outer frame 201 downward, the outer frame 201 compresses the first spring 203, and at the same time the outer frame 201 drives the cleaning brush 205 to move downward. When the first servo motor 202 works, it drives the cleaning brush 205 to rotate through the transmission device 204, and the cleaning brush 205 cleans the inside of the demolding device 5;

[0030] Specifically, on the basis of the above-mentioned Example 1, when the tablet press works, it pushes the outer frame 201 downward, the outer frame 201 compresses the first spring 203, and at the same time the outer frame 201 drives the cleaning brush 205 to move to the designated position. The external control panel controls the first servo motor 202 to work. When the first servo motor 202 works, it drives the transmission device 204 to work, and the transmission device 204 drives the cleaning brush 205 to rotate, and the cleaning brush 205 cleans the inside of the demolding device 5.

The outer wall of the inner frame 506 abuts against one ends of the plurality of second springs 504 and is movably connected to the bottoms of the plurality of inner molds 505. The bottom of the inner frame 506 is detachably connected to the output end of the air cylinder 6. Wherein, when the air cylinder 6 works, it drives the inner mold 505 to move through the inner frame 506. Limited by the limiting frame 501, the roller 502 cooperates with the connecting rod 503 to drive the inner mold 505 to move inward, and the inner molds 505 are combined in pairs;

[0032] In the specific implementation process, it is particularly pointed out that when the air cylinder 6 works, it drives the inner frame 506 to move, the inner frame 506 drives the inner mold 505 to move upward, the limiting frame 501 squeezes the roller 502 to drive the connecting rod 503 to move, and when the connecting rod 503 moves, it drives the inner mold 505 to move inward to complete the mold closing of the two inner molds 505;

[0033] Furthermore, two discharge ports 10 are installed on the inner wall of the outer mold 4;

[0034] In the specific implementation process, it is particularly pointed out that the discharge port 10 facilitates the discharge of the formed tablets from the inside of the outer mold 4 to the outside;

[0035] Specifically, on the basis of the above-mentioned Embodiment 1, the external control panel controls the air cylinder 6 to work. When the air cylinder 6 works, it drives the inner frame 506 to move upward, the inner frame 506 drives the inner mold 505 to move upward, the limiting frame 501 squeezes the roller 502 to move, the roller 502 drives the connecting rod 503 to move, the connecting rod 503 drives the inner mold 505 to move upward and inward, and the inner mold 505 moves inward to complete the mold closing. After the inner mold 505 completes the mold closing, the powder inside the inner mold 505 is extruded by the tablet press. When the air cylinder 6 drives the inner frame 506 to move downward, the inner mold 505 is separated to facilitate the taking out of the tablets.
