[0002] In order to prevent and treat animal diseases, it is necessary to compress the corresponding medicine powder into tablets for storage and animal consumption. At present, the production of tablets is generally completed by extrusion of an upper die and a lower die. For example, there is a utility model pharmaceutical tablet pressing device, the announcement number of which is CN221365999U.

[0003] The above technical solution still has the following deficiencies when used:

[0004] 1. The above technical solution is completed by extrusion cooperation between the upper die and the lower die when pressing the tablets. However, after the extrusion is completed, the staff needs to take out the tablets and add powder to facilitate the subsequent tableting, which not only increases the work intensity of the staff, but also seriously affects the efficiency of drug manufacturing;

[0005] 2. In the pharmaceutical process, tablet compression may fail, resulting in defective products. After these defective products are mixed with good products, they need to be separated in the subsequent process;

[0006] 3. When pressing tablets, the dosage of the tablets cannot be adjusted as needed due to the size limitation of the medicine box;

DETAILED DESCRIPTION

[0053] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0054] Example 1

[0055] Reference Figure 1 , Figure 2 and Figure 4 The tablet press is used in the field of veterinary drug processing equipment, and mainly includes a frame 1, and a fixed plate 2 is fixed to one side of the frame 1. A rotating die 3 is rotatably connected to the fixed plate 2 through a bearing, and a plurality of die grooves 12 are designed inside the rotating die 3 for containing the drug powder to be pressed.

[0056] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A rotating plate 5 is provided above the rotating die 3. A plurality of upper die heads 7 are slidably inserted into the rotating plate 5. These upper die heads 7 cooperate with the die groove 12 and are used to contact the medicine powder in the die groove 12 during the pressing process. Below the fixed plate 2, a lifting plate 13 is slidably connected to the inner wall of one side of the frame 1, and a plurality of lower die heads 14 are placed on the top of the lifting plate 13. The top ends of these lower die heads 14 can slide and extend into the die groove 12, and cooperate with the upper die head 7 and the die groove 12 to complete the pressing of the tablets.

[0057] Reference Figure 1 and Fig. 9In addition, a collecting box 33 is fixedly provided on one side of the frame 1 for collecting the compressed tablets. An inclined screen plate 34 is slidably provided in the collecting box 33, and the inclined screen plate 34 can screen good and bad tablets.

[0058] Reference Figure 1-Figure 4 The tablet pressing structure mainly includes a rotating shaft 4 rotatably arranged on the inner wall of the top of the frame 1, and a driving motor 6 fixed on the top of the frame 1. The output shaft of the driving motor 6 is fixedly connected to the top of the rotating shaft 4 through a coupling, thereby driving the rotating shaft 4 to rotate. The rotating disk 5 and the rotating mold 3 are both fixedly sleeved on the outer wall of the rotating shaft 4 and rotate with it.

[0059] Reference Figure 1 , Figure 3 and Figure 4 The outer walls of the plurality of upper die heads 7 are sleeved with first springs 8, the bottom ends of the first springs 8 are fixedly connected to the top of the rotating disk 5, and the top ends are fixedly connected to the outer walls of the upper die heads 7. In this way, when the upper die heads 7 contact the first arc-shaped inclined surface 11 on the first arc-shaped plate 10, they are squeezed and move downward until they are inserted into the die groove 12. At the same time, a second arc-shaped plate 17 is provided on the top of the lifting plate 13, and the second arc-shaped inclined surface 18 thereon cooperates with the lower die head 14 to drive the lower die head 14 to move upward to eject the medicine in the die groove 12.

[0060] Specifically, as the rotating mold 3 and the rotating disk 5 rotate, the upper die head 7 extends downward under the action of the first arc-shaped inclined surface 11 and is inserted into the die groove 12, and the top of the lower die head 14 also extends into the die groove 12 synchronously. At this time, the upper die head 7, the lower die head 14 and the die groove 12 cooperate to press the powder in the die groove 12 into tablets. Subsequently, the rotating shaft 4 continues to drive the rotating mold 3 and the rotating disk 5 to rotate, and the upper die head 7 is separated from the first arc-shaped plate 10, and moves up and resets under the action of the first spring 8. At the same time, the lower die head 14 continues to move up under the cooperation of the second arc-shaped inclined surface 18, and ejects the tablets in the die groove 12 to the top of the rotating mold 3.

[0061] Reference Figure 4 and Fig. 9 The screening structure is mainly composed of a plurality of arc-shaped protrusions 29 fixed to the bottom of the rotating mold 3, and the tops of these arc-shaped protrusions 29 are slidably connected to the bottom of the fixed plate 2. In addition, a transverse rod 36 is slidably penetrated on one side of the collection box 33, one end of which extends to the bottom of the fixed plate 2 and cooperates with the arc-shaped protrusions 29, and the other end extends into the collection box 33 and touches the bottom of the inclined screen plate 34. The outer wall of the transverse rod 36 is sleeved with a tension spring 37 fixedly connected to the inner wall of one side of the collection box 33, which is used to drive the transverse rod 36 to reset. An arc-shaped material guide plate 32 is fixed on the top of the rotating mold 3 to discharge the ejected tablets into the collection box 33.

[0062] Specifically, when the rotating mold 3 rotates, the arc-shaped protrusion 29 will continuously contact the transverse rod 36 and push it to move outward, while the tension spring 37 continuously drives the transverse rod 36 to reset inward. In this way, the reciprocating movement of the transverse rod 36 will drive the inclined screen plate 34 to vibrate up and down in the collection box 33, thereby realizing the screening of tablets. Good tablets will be discharged to the outside through the discharge port 35 along the inclined surface of the inclined screen plate 34 for collection, while defective tablets will be left in the collection box 33 for subsequent processing.

[0063] Reference Figure 2 , Figure 6 and Figure 7 The drug feeding structure is mainly composed of an arc-shaped drug injection box 23 arranged on the top of the rotating mold 3, whose bottom touches the top of the rotating mold 3 and is used to inject drug powder into the mold groove 12. The arc-shaped drug injection box 23 reciprocates in the fixed plate 2 to ensure that the drug powder can be evenly and fully added to each mold groove 12.

[0064] Reference Figure 2 , Figure 6 and Figure 7 The dosing structure further includes a rectangular hole 26 provided in the fixed plate 2. The size and shape of the rectangular hole 26 must be precisely designed to ensure that the push plate 27 can slide smoothly therein. An arc block 28 is fixed to one side of the push plate 27. The arc block 28 is located below the fixed plate 2 and is designed with a profile that matches the arc convex block 29 on the rotating mold 3. When the rotating mold 3 rotates with the rotating shaft 4, the arc convex block 29 will periodically contact the arc block 28, thereby driving the push plate 27 to move outward.

[0065] Reference Figure 2 , Figure 6 and Figure 7 , a push rod 24 is inserted into the push plate 27, one end of the push rod 24 passes through the inner wall of one side of the frame 1, and the other end is fixedly connected to the arc-shaped injection box 23. A second spring 25 is sleeved on the outer wall of the push rod 24, one end of the spring is fixedly connected to the inner wall of one side of the frame 1, and the other end is fixedly connected to the outer wall of the push rod 24. When the arc-shaped protrusion 29 contacts the arc-shaped block 28 and pushes the push plate 27 to move outward, the push rod 24 will move accordingly and compress the second spring 25. When the arc-shaped protrusion 29 separates from the arc-shaped block 28, the elastic force of the second spring 25 will drive the push rod 24 and the arc-shaped injection box 23 to reset.

[0066] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7The medicine storage box 21 is fixed to one side of the frame 1, and its bottom is connected to the top of the arc-shaped medicine injection box 23 through the medicine discharge hose 22. When the driving motor 6 drives the rotating mold 3 and the rotating disk 5 to rotate simultaneously through the rotating shaft 4, the mold groove 12 on the rotating mold 3 will move to the bottom of the arc-shaped medicine injection box 23 in sequence. At this time, due to the reciprocating movement of the push rod 24 and the arc-shaped medicine injection box 23, the medicine powder in the medicine storage box 21 will be accurately injected into the mold groove 12 through the medicine discharge hose 22, preparing for the subsequent tablet pressing.

[0067] Reference Figure 1 , Figure 2 and Figure 5 The control structure includes a support plate 19 fixed on the inner wall of one side of the frame 1, and the support plate 19 is located below the lifting plate 13. The internal thread of the support plate 19 passes through a screw rod 20, and the top end of the screw rod 20 is rotatably connected to the bottom of the lifting plate 13. In this way, by rotating the screw rod 20, the lifting height of the lifting plate 13 can be controlled. The top of the lifting plate 13 is provided with an arc groove 15, and the arc groove 15 is slidably matched with the second arc plate 17 to ensure that the second arc plate 17 can maintain a stable motion trajectory during the lifting process of the lifting plate 13. At the same time, a fixed rod 16 is slidably passed through the inner wall of the bottom of the arc groove 15, and the top end of the fixed rod 16 is fixedly connected to the bottom of the second arc plate 17, and the bottom end is fixedly connected to the top of the support plate 19. In this way, no matter how the lifting plate 13 is lifted or lowered, the second arc plate 17 will remain at the same height so as to cooperate with the lower die head 14 to discharge the tablets from the die groove 12.

[0068] Specifically, by adjusting the rotation amount of the screw 20, the lifting height of the lifting plate 13 can be controlled, thereby controlling the dosage of the medicine powder placed in the die groove 12. This design is flexible and accurate, and can meet the pressing requirements of tablets of different specifications.

[0069] Reference Figure 8 A through hole 30 is provided at the top of the arc-shaped medicine injection box 23, and a scraper 31 is fixed to the inner wall of one side of the through hole 30. The top of the scraper 31 is designed to fit the bottom of the upper die head 7 so as to scrape off the medicine powder attached to the bottom of the upper die head 7 when the upper die head 7 rotates and passes by. In this way, the waste of medicine powder can be avoided, and the medicine powder at the bottom of the upper die head 7 can be prevented from affecting the subsequent tablet pressing.

[0070] Specifically, when the rotating disk 5 drives the upper die head 7 to rotate, the bottom end of the upper die head 7 will pass through the scraper 31 on the top of the arc-shaped medicine injection box 23 in sequence. At this time, the scraper 31 will scrape the medicine powder at its bottom into the through hole 30, and then return it to the medicine storage box 21 through the medicine discharge hose 22 or undergo other treatments. This design is simple and effective, and can significantly improve the production efficiency and product quality of the high-speed tablet press for veterinary tablets.

[0071] Reference Figure 4 and Figure 5 In the design of the high-speed tablet press for veterinary tablets, the lifting plate 13 is one of the key components, and a circular hole is specially designed on the top of the lifting plate 13. The position and size of this circular hole are precisely calculated to ensure that the bottom end of the rotating shaft 4 can smoothly and stably extend into the inside. This design not only significantly enhances the stability of the rotating shaft 4 during high-speed operation and reduces the risk of failure due to vibration or deviation, but also provides the necessary space for the lifting plate 13 to move up and down, ensuring the smooth progress of the entire tableting process.

[0072] In order to precisely control the up and down movement range of the upper die head 7 and prevent it from excessively moving upward and affecting subsequent operations, a limit ring 9 is fixedly sleeved on the outer wall of the upper die head 7. The limit ring 9 is located below the rotating disk 5, and its position and size are precisely calculated to ensure that when the first spring 8 pushes the upper die head 7 to move upward and reset, the limit ring 9 can limit the upper die head 7 in a timely and effective manner. This design ensures the stability of the upper die head 7 during the reset process, and also facilitates the subsequent operation of the scraper 31, so that the scraper 31 can easily and thoroughly scrape off the powder attached to the bottom of the upper die head 7, thereby ensuring the purity and consistency of the tablets.

[0073] Through the above embodiments, the present invention provides a high-speed tablet press for veterinary tablets that is compact in structure, easy to operate, efficient and reliable, and can significantly improve the production efficiency and product quality of veterinary tablets.

[0074] Example 2

[0075] refer to Fig.10 and Fig.11 , improved on the basis of Example 1: In order to further improve the filling effect of the powder in the die groove 12, we designed a groove 38 at the bottom of the rotating mold 3, and fixed a plurality of arc-shaped paddles 39 on the inner wall of the top thereof. At the same time, a vertical plate 40 is fixed on the top of the lifting plate 13, and the top of the vertical plate 40 extends into the groove 38. At the top of the vertical plate 40, we slidably connect a knocking rod 41, and the bottom of the knocking rod 41 is slidably penetrated by a guide rod 42 through the base, and one end of the guide rod 42 is fixedly connected to one side of the vertical plate 40. On the outer wall of the guide rod 42, we sleeve a third spring 43, one end of which is fixedly connected to the vertical plate 40, and the other end is fixedly connected to the base. In addition, a pin 44 is also fixed on the top of the knocking rod 41, and the pin 44 cooperates with the arc-shaped paddle 39 to drive the knocking rod 41 to move inward when the rotating mold 3 rotates.

[0076] Specifically, when the rotating mold 3 rotates with the main shaft, the plurality of arc-shaped paddles 39 will contact the pins 44 in sequence and push the knocking rod 41 to move toward the middle. When the pins 44 and the arc-shaped paddles 39 are out of contact, the knocking rod 41 moves rapidly outward under the pulling force of the third spring 43 and knocks the inner wall of the groove 38. This intermittent knocking action can effectively vibrate the powder in the mold groove 12, so that it is more tightly and evenly filled in the mold groove 12. This design significantly improves the filling efficiency and filling quality of the powder, and avoids the problem of inaccurate tablet dosage caused by insufficient powder filling.

[0077] A method for using a high-speed tablet press for veterinary tablets comprises the following steps:

[0078] S1. When making medicine, the medicine storage box 21 puts the medicine powder into the arc-shaped medicine injection box 23 through the medicine discharge hose 22, and the driving motor 6 drives the rotating mold 3 and the rotating disk 5 to rotate through the rotating shaft 4 at the same time. The rotating mold 3 synchronously drives the arc-shaped protrusion 29 to rotate. The arc-shaped protrusion 29 cooperates with the arc-shaped block 28 and the second spring 25 to intermittently drive the push rod 24 and the arc-shaped medicine injection box 23 to reciprocate. Therefore, when the rotating mold 3 rotates, the mold groove 12 moves into the arc-shaped medicine injection box 23. The reciprocating movement of the arc-shaped medicine injection box 23 can inject the medicine powder into the mold groove 12, which is convenient for the compression of tablets in the later stage;

[0079] S2. With the rotation of the rotating mold 3 and the rotating disk 5, the upper die head 7 extends into the die groove 12 under the action of the first arc-shaped inclined surface 11 on one side of the first arc-shaped plate 10, and the top of the lower die head 14 extends into the die groove 12. At this time, the cooperation between the lower die head 14, the upper die head 7 and the die groove 12 can press the powder in the die groove 12 into tablets. The rotating shaft 4 continues to drive the rotating mold 3 and the rotating disk 5 to rotate. The upper die head 7 is separated from the first arc-shaped plate 10 and moves up and resets under the action of the first spring 8. The lower die head 14 moves up under the cooperation of the second arc-shaped inclined surface 18 at the top of the second arc-shaped plate 17. The lower die head 14 pushes the tablets in the die groove 12 to the top of the rotating mold 3 to discharge the tablets.

[0080] S3. In addition, when the rotating die 3 rotates, the tablets are discharged onto the inclined screen plate 34 along the arc-shaped guide plate 32 under the action of centrifugal force. In addition, the cooperation of the arc-shaped protrusion 29, the transverse rod 36 and the tension spring 37 continuously drives the inclined screen plate 34 to slide up and down in the collection box 33, so the inclined screen plate 34 can drive the tablets to vibrate, which is used to screen good tablets and bad tablets, and the good tablets are discharged to the outside through the discharge port 35 along the inclined surface of the inclined screen plate 34 for collection, while the bad tablets are collected in the collection box 33, which is convenient for later crushing and recycling;

[0081] S4, when the rotating shaft 4 drives the rotating die 3 and the rotating disk 5 to rotate, the rotating disk 5 drives the upper die head 7 to rotate, and at this time, the scraper 31 on the top of the arc-shaped medicine injection box 23 just touches the bottom end of the upper die head 7, which is used to scrape the medicine powder at the bottom end of the upper die head 7 into the through hole 30, so as to avoid the waste of medicine powder and prevent the medicine powder at the bottom end of the upper die head 7 from affecting the subsequent tablet pressing;

[0082] S5. When the dosage of the compressed tablet needs to be adjusted, the screw 20 only needs to be rotated to control the lifting and lowering of the lifting plate 13 through the screw 20, thereby controlling the dosage of the medicine powder placed in the die groove 12, and the second curved plate 17 maintains a constant height under the action of the fixing rod 16, so the cooperation between the second curved plate 17 and the lower die head 14 can still discharge the tablet from the die groove 12;

[0083] S6. In addition, during the process of injecting medicine powder into the mold groove 12 by the arc-shaped medicine injection box 23, the rotating mold 3 synchronously drives the multiple arc-shaped paddles 39 to rotate, and the cooperation between the arc-shaped paddles 39 and the pin 44 drives the knocking rod 41 to move toward the middle. When the pin 44 and the arc-shaped paddles 39 are out of contact, the knocking rod 41 moves outward under the pulling force of the third spring 43 to knock the inner wall of the groove 38, so that when injecting medicine powder into the mold groove 12, the medicine powder can be fully filled into the mold groove 12, thereby avoiding insufficient filling of medicine powder in the mold groove 12 and causing inaccurate dosage of tablets.

[0084] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 6 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0085] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
