Description

Technical Field

[0001] This utility model relates to the field of tablet press technology, and in particular to an infrared tablet press. Background Technology

[0002] An infrared tablet press is an instrument used by infrared spectrometers to prepare powder sample tablets. In operation, the powder sample is first placed into the mold of the press, and then the press is manually operated to compress the powder into thin tablets. Existing technology, patent number CN202020741091.5, discloses a high-precision infrared tablet press. It uses a limiting assembly to install a lower pressing head and a support plate inside the lower pressing base. The support plate is limited by limiting rods installed at four corners, improving the stability of its movement. Simultaneously, the lower end of the lower pressing head moves within the lower pressing base via a slider and a groove. The slider welded to the lower end of the lower pressing head moves within a groove on the surface of the lower pressing base, further improving the stability of the lower pressing head's movement and increasing the safety of the tablet pressing process. However, after pressing, because the tablet is located in the pressing groove, the lower pressing head needs to be removed and inverted to be tapped to extract the tablet. This removal operation is cumbersome and can easily damage the tablet. Summary of the Invention

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figures 1 to 5As shown, this utility model provides an infrared tablet press, including a base 10, a mold seat 20 on the base 10, multiple sets of columns 11 on the base 10, a top plate 12 on the upper end of the multiple sets of columns 11, a pressing mechanism 30 movably inserted into the top plate 12 at a position corresponding to the mold seat 20, a mold groove 21 opened at the upper end of the mold seat 20, a tablet press 40 detachably installed in the mold groove 21, and the top of the tablet press 40 is located in the mold seat 20. On both opposite sides of the tableting mold 40, there are movable limiting components 50 that can extend into the mold groove 21. The movable limiting components 50 can prevent the tableting mold 40 from moving upward. The tableting mold 40 has a tableting groove 41 inside. The bottom of the tableting mold 40 has a drug dispensing top hole 42 that communicates with the tableting groove 41. A movable base plate 43 is detachably installed in the tableting groove 41. The bottom of the mold base 20 has a drug dispensing mechanism 60 that can push the movable base plate 43 upward out of the tableting groove 41. The size of the drug dispensing top hole 42 should be smaller than the size of the tableting groove 41 so that the bottom of the tableting mold 40 can support the movable base plate 43. The drug powder to be processed is added to the movable base plate 43 in the tableting groove 41.

[0025] See Figure 2 and Figure 4 In a specific embodiment of this application, the dispensing mechanism 60 includes a lifting cylinder 61. The bottom of the mold base 20 has an installation area 22 that communicates with the tableting groove 41. The lifting cylinder 61 is installed within the installation area 22, and its movable end can extend into the dispensing top hole 42. The lifting cylinder 61 is a miniature cylinder; after the tablets are pressed, controlling its lifting position pushes the movable base plate 43 upwards, simultaneously causing the tablets to exit the tableting groove 41.

[0026] See Figure 4 and Figure 5In one specific embodiment of this application, to prevent the dispensing mechanism 60 from pushing the tableting mold 40 out of the mold groove 21, both sets of movable limiting components 50 include wedge-shaped sliders 51. Slide grooves 23 are provided on opposite sides of the top of the tableting mold 40 within the mold base 20. One end of the wedge-shaped slider 51 is movably mounted in the slide groove 23 via a return spring 52, and the other end of the wedge-shaped slider 51 can extend movably into the mold groove 21. Specifically, the wedge-shaped surface of the wedge-shaped slider 51 is positioned above the outward-facing end. The wedge-shaped slider 51 can move laterally along the slide groove 23, retract into the slide groove 23 to insert or remove the tableting mold 40, or extend out of the mold groove 21 to limit the tableting mold 40. When the tableting mold 40 is placed into the mold slot 21, the bottom of the tableting mold 40 contacts the wedge-shaped surface of the wedge-shaped slider 51. The wedge-shaped surface can convert vertical movement into horizontal movement, so the wedge-shaped slider 51 can be pushed back into the slide groove 23 at the same time, and the return spring 52 is compressed, so the tableting mold 40 can be smoothly placed into the mold slot 21. After the tableting mold 40 is placed, the wedge-shaped slider 51 is no longer under force, and the return spring 52 can automatically return and push the wedge-shaped slider 51 outward so that the wedge-shaped slider 51 abuts against the top of the tableting mold 40, limiting the tableting mold 40. When the tableting mold 40 needs to be replaced, the wedge-shaped slider 51 can be manually pushed to both sides to release the limitation and take out the tableting mold 40. For convenient operation, a pull rope can also be set on the tableting mold 40.

[0027] See Figure 1 and Figure 2 The pressing mechanism 30 includes a lead screw 31. A socket 13 is provided on the top plate 12, and a nut is provided inside the socket 13. The lead screw 31 is movably installed inside the nut, and a pressing head 32 is provided on the lower end of the lead screw 31. A handwheel 35 is provided on the upper end of the lead screw 31 to facilitate rotation. Further, the pressing head 32 includes a pressing column 33 and a sealing column 34 that can respectively cooperate with the tableting groove 41 and the mold groove 21. The outer wall of the pressing column 33 can fit against the inner wall of the tableting groove 41 to press the powder inside the tableting groove 41 downwards; simultaneously, the outer wall of the sealing column 34 can fit against the inner wall of the mold groove 21 to seal the interior of the mold groove 21, facilitating pressurization.

[0028] Furthermore, to ensure more uniform tablet compression, the mold base 20 is equipped with an air extraction pipe 24 that connects to the mold groove 21. Moreover, the air extraction pipe 24 can be connected to an external negative pressure device, and a pressure gauge can be installed on the pipe to monitor the pressure inside the mold base 20 and thus determine the tablet forming status.

[0029] This utility model discloses an infrared tablet press. By setting a movable base plate 43 at the bottom of the tablet pressing mold 40 and opening a drug dispensing top hole 42, the drug powder is added into the tablet pressing groove 41 for tableting. After tableting, the drug dispensing mechanism 60 can push the movable base plate 43 upward from the drug dispensing top hole 42, which can push the formed tablet upward out of the tablet pressing groove for easy removal. At the same time, by setting movable limiting components 50 on opposite sides of the top of the tablet pressing mold 40, the tablet pressing mold can be limited to prevent the drug dispensing mechanism 60 from pushing the tablet pressing mold 40 upward, ensuring that the tablet can be smoothly pushed out of the tablet pressing groove 41.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
