[0025] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the accompanying drawings of the specification.

[0026] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or selectively exclusive embodiment with other embodiments. The present utility model provides the following embodiments.

[0028] From Figure 1 and Figure 2 As shown, the compression stroke control mechanism for a tablet press includes a housing 1, a containing component 2, a pressing component 3, and a pressing member 4. The pressing component 3 is fixedly installed on the surface of the housing 1. The containing component 2 is slidably installed inside the housing 1. The output end of the pressing component 3 is fixedly installed with the pressing member 4. One side of the inner wall of the housing 1 is fixedly installed with an adjusting mechanism 5. The adjusting mechanism 5 includes a moving end 54 and a release electrode plate 55. The moving end 54 is slidably installed inside the housing 1, and the release electrode plate 55 is fixedly installed on the side of the moving end 54.

[0029] During use, the pharmaceutical powder to be processed is poured into the containing component 2. Then, the containing component 2 is pushed to move the containing component 2 to the target position inside the housing 1. And the corresponding pressing member 4 for pressing the tablet is selected and installed at the bottom end of the pressing component 3. Then, by using the pressing component 3, the pressing member 4 is pushed to move downward to extrude the pharmaceutical powder contained in the containing component 2. And during the movement of the pressing component 3, by using the adjusting mechanism 5, the stroke of the pressing component 3 during operation can be flexibly adjusted. Through the operation of the components inside the adjusting mechanism 5, the position of the moving end 54 itself can be adjusted flexibly and accurately, so that the release electrode plate 55 moves to the target height. When the pressing component 3 pushes the pressing member 4 to move, the components on the side of the pressing component 3 will automatically come into contact with the release electrode plate 55. Once the two come into contact, the existing controller installed inside the housing 1 will stop the operation of the pressing component 3 and reset the pressing component 3 to achieve the control of the overall compression stroke of the device.

[0030] From the attached Figure 2As shown, in this embodiment, the adjusting mechanism 5 further includes a baffle 51, a lead screw 52, a guide rod 53, and a driving motor 56. The baffle 51 is symmetrically and fixedly installed on the inner wall of the outer housing 1. The lead screw 52 is rotatably installed between the baffles 51. The guide rod 53 is fixedly installed between the baffles 51. The lead screw 52 and the guide rod 53 are parallel in position. The lead screw 52 is in threaded engagement with the mobile end 54, and the guide rod 53 is slidably connected to the mobile end 54. The driving motor 56 is fixedly installed at the bottom end of one set of the baffles 51, and the output end of the driving motor 56 is fixedly connected to the end of the lead screw 52.

[0031] During use, by starting the driving motor 56, the output end of the driving motor 56 drives the lead screw 52 to rotate between the baffles 51. When the lead screw 52 rotates, the mobile end 54 will slide along the external thread on the surface of the lead screw 52. According to the rotation direction of the lead screw 52, the mobile end 54 will move in different directions, so as to control the height of the mobile end 54 and release the electrode plate 55. Moreover, by installing the driving motor 56, the number of turns of the rotation of the lead screw 52 can be accurately adjusted, realizing the precise adjustment of the moving distance of the release electrode plate 55, which is convenient for stably pressing and processing medicines with different thicknesses.

[0032] As shown Figure 3 As shown, in this embodiment, the pressing member 4 includes a fixing plate 41, a threaded end 42, and a pressing plate 43. A fixing plate 41 is arranged at the bottom end of the output end of the pressing assembly 3. The threaded end 42 is fixedly installed on the upper surface of the fixing plate 41. The threaded end 42 is in threaded connection with the pressing assembly 3. The pressing plate 43 is fixedly installed at the bottom end of the fixing plate 41.

[0033] During use, by selecting the pressing plate 43 corresponding to the medicine pressing specification required, and then using the threaded end 42, the fixing plate 41 and the pressing plate 43 are fixedly installed at the bottom end of the pressing assembly 3, completing the installation and positioning of the components, which is convenient for quickly pressing medicines of the same batch and the same specification, changing the operation mode of placing the pressing die on the upper surface of the containing assembly 2 when processing medicines now, and simplifying the overall operation steps.

[0034] As shown Figure 4 As shown, in this embodiment, the pressing member 4 further includes a rotating groove 44. The rotating grooves 44 are equidistantly arranged outside the fixing plate 41.

[0035] During use, through the use and arrangement of the rotating groove 44, when the staff rotates the fixing plate 41, the finger part can obtain better support and friction, and the rotation of the entire fixing plate 41 is more relaxed and labor-saving.

[0036] As shown Figure 4As shown, in this embodiment, the pressing assembly 3 includes a top plate 31, an electric push rod 32, a lifting rod 33, and a mounting plate 34. The top plate 31 is fixedly installed on the upper surface of the outer casing 1. The electric push rod 32 is fixedly installed at the top of the top plate 31. The lifting rod 33 is fixedly installed at the output end of the electric push rod 32. The lifting rod 33 is slidably connected to the outer casing 1. The lifting rod 33 passes through the top plate 31 and enters the interior of the outer casing 1. The mounting plate 34 is fixedly installed at the bottom end of the lifting rod 33. The mounting plate 34 is threadedly connected to the threaded end 42.

[0037] During use, by starting the electric push rod 32, the lifting rod 33 moves downward along with the output end of the electric push rod 32, pushing the mounting plate 34 and the pressing member 4 to squeeze downward, squeezing the medicine powder inside the containing assembly 2 to realize the tablet pressing operation of the medicine.

[0038] As shown by the appendix Figure 4 As shown, in this embodiment, the pressing assembly 3 further includes a mating electrode plate 35. The mating electrode plate 35 is fixedly installed on the side surface of the mounting plate 34. The mating electrode plate 35 is located directly above the release electrode plate 55.

[0039] During use, due to the installation of the mating electrode plate 35, when the mounting plate 34 pushes the pressing member 4 to move, the mating electrode plate 35 will move together with the mounting plate 34. When the mating electrode plate 35 moves to the upper end of the release electrode plate 55 and the bottom surface of the mating electrode plate 35 contacts the upper surface of the release electrode plate 55, the electrode plates inside the mating electrode plate 35 and the release electrode plate 55 are attached to each other and the internal circuit is connected. At this time, the existing controller inside the outer casing 1 will receive this signal, immediately stop the operation of the electric push rod 32, and drive the electric push rod 32 to reset, realizing the control of the overall pressing distance and stroke of the pressing assembly 3.

[0040] As shown by the appendix Figure 5 and Figure 6 As shown, in this embodiment, the containing assembly 2 includes a moving plate 21, an outer bin 22, a buffer assembly 23, a containing bin 24, and a limit hook 25. The moving plate 21 is slidably installed on the inner wall of the outer casing 1. The outer bin 22 is arranged on the surface of the moving plate 21. The buffer assembly 23 is slidably installed inside the outer bin 22. The containing bin 24 is slidably installed at the top of the buffer assembly 23. The limit hook 25 is rotatably installed on the side surface of the buffer assembly 23.

[0041] In use, first place the outer bin 22 on the surface of the moving plate 21, then install the buffer assembly 23 inside the outer bin 22, and then place the storage bin 24 on the top of the buffer assembly 23. At this time, pour the drug powder to be processed into the storage bin 24. Then, through the cooperation of the moving plate 21 and the inner wall structure of the outer housing 1, move the positions of the outer bin 22 and the moving plate 21 to move the storage bin 24 directly below the pressing assembly 3, which is convenient for the subsequent pressing assembly 3 to press and process the drug powder inside the storage bin 24. And when the storage bin 24 is being pressed, the buffer assembly 23 will slide inside the outer bin 22. At this time, the limit hook 25 automatically snaps into the column on the side of the outer bin 22 to fix the position of the buffer assembly 23, preventing the entire storage bin 24 from suddenly popping out when the pressing assembly 3 disengages from the surface of the storage bin 24, causing the drugs inside the storage bin 24 to fall off.

[0042] The above content further elaborates on the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model pertains, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, which should all be regarded as falling within the protection scope determined by the claims submitted for the present utility model.
