DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0031] With reference to Figure 1 and Figure 2 , the utility model provides an embodiment: a tablet press for medicine production, including machine body 1, machine body 1 inside fixedly connected with telescopic rod 2, telescopic rod 2 output fixedly connected with upper mold 5, for through exerting pressure to the medicine powder and press;

[0032] The feeding assembly comprises a feeding shell 9, which is slidingly connected inside the guide rail 4, so that the feeding shell 9 can slide smoothly in the guide rail 4, thereby realizing accurate feeding of the medicine powder. The feeding shell 9 is fixedly connected with a feeding pipe 10 at the top, which is used to provide the medicine powder from outside and pour it into the feeding shell 9. The guide rail 4 is provided with a lower mold 3 inside, which is embedded with the upper mold 5, and the medicine powder is pressed into tablets by applying pressure. The reciprocating assembly is arranged on the outer wall of the machine body 1, which can ensure the smooth reciprocating movement of the feeding shell 9 in the guide rail 4, thereby accurately controlling the addition amount and position of the medicine powder. The bottom of the feeding shell 9 is provided with a sealing assembly, which comprises a sealing ring 11 fixedly connected at the bottom of the feeding shell 9, and the bottom of the sealing ring 11 is in close contact with the inner wall of the guide rail 4, so as to prevent the medicine powder from leaking during feeding and discharging, and improve the sealing performance and stability of the feeding system. The reciprocating assembly comprises a motor 6 fixedly connected on one side of the machine body 1, and the output end of the motor 6 is fixedly connected with a rotating disc 7 for driving the connecting rod 8. One end of the connecting rod 8 is rotatably connected to the top of the feeding shell 9, so as to ensure the smooth and accurate reciprocating movement of the feeding shell 9 in the guide rail 4, thereby realizing automatic feeding.

[0033] Specifically, when the tablets are pressed, first, the feeding pipe 10 is connected with the medicine powder source, and the medicine powder is accurately poured into the inside of the feeding shell 9. Then, the output end of the motor 6 drives the rotating disc 7 to start rotating, and the rotating disc 7 drives the feeding shell 9 to slide along the guide rail 4 through the connecting rod 8, thereby realizing uniform feeding of the medicine powder. The feeding shell 9 and the guide rail 4 are tightly sealed by the sealing ring 11, which effectively prevents the medicine powder from leaking and ensures the accurate feeding of the medicine powder. After the medicine powder falls into the lower mold 3, the output end of the telescopic rod 2 is extended, and the upper mold 5 is accurately embedded into the lower mold 3, thereby uniformly compacting the medicine powder and forming tablets. After each feeding, the movement of the feeding shell 9 not only makes the medicine powder be pressed into tablets, but also pushes the tablets to be smoothly discharged from the mold, thereby ensuring the smooth discharge of the tablets.

[0034] Reference Figure 3The body 1 is internally fixedly connected with a limiting column 13, and a sliding block 15 is slidably connected to the outer wall of the limiting column 13. The limiting column 13 can prevent excessive movement of the sliding block 15 and ensure that the sliding block 15 slides within a specified range. The body 1 is also internally fixedly connected with a support rod 12, and a limiting groove 14 is formed in the support rod 12. The limiting groove 14 provides a sliding track for the sliding block 15 and limits the movement direction and position of the sliding block 15, thereby ensuring the accuracy and stability of the system. The top of the sliding block 15 is fixedly connected with a top rod 17, the top rod 17 is slidably connected inside the support rod 12, and the top rod 17 and the sliding block 15 are arranged inside the limiting groove 14. The sliding design of the top rod 17 allows the top rod 17 to move smoothly within the support rod 12, ensuring that the pressure can be accurately controlled during tablet pressing. The top rod 17 is slidably connected inside the lower mold 3, ensuring the coordinated work between the top rod 17 and the lower mold 3, and ensuring that the tablets can be pressed at the correct position. A tension spring 16 is sleeved on the outer wall of the limiting column 13, one end of the tension spring 16 is fixedly connected inside the body 1, and the other end of the tension spring 16 is fixedly connected to the top of the sliding block 15. The tension spring 16 functions as a reset, helping the sliding block 15 and the top rod 17 to return to their original positions during pressing, ensuring the stability and smooth operation of the equipment. At the same time, the tension of the tension spring 16 allows the top rod 17 to rebound in time, ensuring that the shaping process of the tablets is not disturbed.

[0035] Specifically, when the upper mold 5 is lifted during pressing, the lower mold 3 moves downward and stretches the tension spring 16 through the sliding block 15. The tension spring 16 gradually stretches under the action of the lifting force of the upper mold 5 and provides a restoring force. When the upper mold 5 is completely lifted, the top rod 17 starts to move upward relying on the restoring force of the tension spring 16, and the top rod 17 is smoothly ejected from the lower mold 3 through the coordinated action of the sliding block 15 and the tension of the tension spring 16. The upward movement of the top rod 17 pushes the lower mold 3 and the tablets in it to be accurately ejected. The cooperation between the sliding block 15 and the limiting column 13 allows the sliding block 15 to slide accurately within the specified limit range, preventing excessive movement, thereby ensuring that the tablets can be smoothly and cleanly ejected and discharged from the mold.

[0036] Working principle: when using the tablet press for producing medicine, first, the tablets are pressed, the feeding pipe 10 is connected to the medicine powder to make it enter the inside of the feeding shell 9, then the output end of the motor 6 drives the rotating disc 7 to rotate, the rotating disc 7 drives the feeding shell 9 to slide in the guide rail 4 through the connecting rod 8, so that the medicine powder falls into the lower mold 3, the feeding shell 9 and the guide rail 4 are sealed by the sealing ring 11, then the output end of the telescopic rod 2 extends downward to drive the upper mold 5 to embed into the lower mold 3 to press the tablets, and when the feeding shell 9 is reloaded, the tablets are pushed to be discharged, achieving the effect of automatic feeding and discharging;

[0037] When the upper die 5 is lifted and pressed, the lower die 3 is simultaneously pressed and the stretching spring 16 is stretched through the slider 15; when the upper die 5 is lifted, the ejector rod 17 is reset through the pulling force of the stretching spring 16, the stretching spring 16 drives the ejector rod 17 to eject the lower die 3 through the slider 15, and the ejector rod 17 ejects the tablet, the slider 15 is limited through the limiting column 13, and the effect of ejecting the tablet is achieved.

[0038] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
